Nemátodos entomopatógenos procedentes de la rizosfera de suelos maiceros infestados con la gallina ciega Phyllophaga polyphylla Bates.
Provedor de dados: 32
Autores: Negrete García, Román.
Las gallinas ciegas se encuentran entre las plagas de suelo de mayor importancia económica en el mundo, incluyendo México. Considerando que el suelo es el ambiente más favorable para los nematodos entomopatógenos (NEP), es posible recuperar aislamientos de NEP que puedan tener el potencial para ser desarrollados como agentes de control biológico de esta plaga. Por esta razón se llevó a cabo un muestreo en el estado de Guanajuato, una de las regiones agrícolas más importantes de México. La colecta de nematodos se realizó utilizando larvas de Galleria mellonella como cebo en lugares con grandes poblaciones de gallina ciega. Los nematodos obtenidos se identificaron utilizando métodos morfológicos y moleculares. Después, la susceptibilidad de la gallina ciega...

An interdisciplinary field trip to a remote marine lab joined graduate students from fine arts and natural resource science departments to think creatively about the topic of climate change and science communication. We followed a learning cycle framework to allow the students to explore marine ecosystems and participate in scientific lectures, group discussions, and an artist-led project making abstract collages representing climate change processes. Students subsequently worked in small groups to develop environmental communication material for public visitors. We assessed the learning activity and the communication product using pre- and post-field trip participant surveys, focus group discussions, and critiques by art and communication experts of the...

Autores: Tolvanen, Anne; Finnish Forest Research Institute; anne.tolvanen@metla.fi; Kauppila, Pekka; University of Oulu; pekka.kauppila@oulu.fi.
The opinions and perceptions of local communities are central issues in the sustainable management of conservation areas. During 2002 and 2003, we studied the opinions of local people about nature conservation and the development of tourism to investigate whether these opinions were influenced by socioeconomic and demographic factors. Data were collected via a survey of local residents in six areas with different histories of land use, land ownership, conservation, and tourism development. We classified respondents by cluster analysis into three different groups according to their opinions about nature conservation and tourism development: (1) sympathetic to nature conservation, but quite neutral to tourism development (57.7%); (2) critical of nature...

Seabirds as a subsistence and cultural resource in two remote Alaskan communities
Provedor de dados: 7
Autores: Young, Rebecca C.; Department of Biology and Wildlife, Institute of Arctic Biology, University of Alaska Fairbanks; rcyoung@alaska.edu; Kitaysky, Alexander S.; Department of Biology and Wildlife, Institute of Arctic Biology, University of Alaska Fairbanks; askitaysky@alaska.edu; Carothers, Courtney; School of Fisheries and Ocean Sciences, University of Alaska Fairbanks; clcarothers@alaska.edu; Dorresteijn, Ine; Department of Biology and Wildlife, Institute of Arctic Biology, University of Alaska Fairbanks; ine.dorresteijn@gmail.com.
Small rural Alaskan communities face many challenges surrounding rapid social and ecological change.  The role of local subsistence resources may change over time because of changes in social perception, economic need, and cultural patterns of use.  We look at the Bering Sea&amp;#8217;s Pribilof Islands, comprising two very small communities, and investigate the relationship between the local residents and seabirds as a natural resource.  Seabirds may strengthen ties to older ways of life and have potential for future economic opportunities, or modernization may direct interest away from seabirds as a cultural and economic resource.  We conducted a survey and interviews of residents of the two Pribilof Island communities, St. Paul and St. George, to assess...

Joint knowledge production for climate change adaptation: what is in it for science?
Provedor de dados: 7
Autores: Hegger, Dries; Environmental Governance, Copernicus Institute of Sustainable Development, Utrecht University; d.l.t.hegger@uu.nl; Dieperink, Carel; Environmental Governance, Copernicus Institute of Sustainable Development, Utrecht University; c.dieperink@uu.nl.
Both in literature and in practice, it is claimed that joint knowledge production (JKP) by researchers, policy makers, and other societal actors is necessary to make science relevant for addressing climate adaptation. Although recent assessments of JKP projects have provided some arguments in favor of their societal merit, much less is known about their scientific merit. We explored the latter by developing a conceptual framework addressing characteristics of doing JKP as well as hypotheses on potential merits and pitfalls in terms of its process, output, and impact for science. Semistructured interviews with six environmental science research leaders as well as discussions with five researchers involved in past JKP projects were used to start...

Scientific Research or Advocacy? Emotive Labels and Selection Bias Confound Survey Results
Provedor de dados: 7
Autores: Vanclay, Jerome K; Southern Cross University; jvanclay@scu.edu.au.
Robert Costanza presents four compelling visions of the future, but the language he uses to describe them is emotive and value-laden and may bias the survey results. The descriptions and analogies used may evoke responses from the survey participants that reveal more about their reactions to the description than their attitudes toward a given scenario. It is hypothesized that the use of more neutral language may lead to more support for the scenario involving "self-limited consumption with ample resources" that Costanza calls "Big Government." If this hypothesis is correct, then the skeptic's policy that Costanza appears to prefer has the additional advantage of always leading to the favored outcome, regardless of the state of the world.

A 3-year survey was made of several biological markers in mussels (Mytilus edulis) exposed in situ to the oil that came ashore after the wreck of the "Erika" tanker on the Brittany (France) coast in December 1999. The mussel response was assessed using a set of 7 biomarkers, most of them related to the metabolism of organic contaminants. After a series of validation tests, data was evaluated for only 5 biomarkers: acety1cholinesterase (AChE), glutathione S-transferase (GST), catalase (CAT), malondialdehyde (MDA) and deoxyribonucleic acid (DNA) adducts. No significant reductions in GST or CAT levels were observed, levels of DNA adducts and MDA were high during the 6 months immediately following the accident and levels of AChE were significantly lower during...

Les campagnes d'évaluation du stock de coquilles Saint-Jacques en Manche orientale : méthodologie et estimation des indices d'abondance
Provedor de dados: 5
Autores: Vigneau, Joel; Fifas, Spyros; Foucher, Eric.
The methodology used for obtaining absolute abundance indices for Eastern Channel scallop is described in this paper. For the survey (COMOR), stratified multi-stage random sampling is used. The number of sampled units is computed based on variance estimates from the last survey. Knowledge of gear (Brittany dredge with a diving plate) selectivity and efficiency parameters is required for estimating total exploitable biomass and absolute abundance indices by age and strata. Details of the mathematical development of all estimators are given. A non parametric bootstrap provides confidence intervals for all estimates.

The French sardine fishery
Provedor de dados: 5
Autores: Duhamel, Erwan.
This approach of the French sardine fishery shows mainly that pelagic trawlers are targeting less and less sardine, year after year. In an assessment approach, it would be necessary to define an estimation of fishing effort, but it will be very difficult. We are able to compt the number of fishing days, but not the time of fishing (or number of shoots for example for purse seiners) or time of searching schools. So, accessibility and catchability could be certainly more accurate than the fishing effort for assesment purposes.

Bonamiosis, favoured by change of temperature and stress, causes mortalities in the adult flat oyster Ostrea edulis in the majority of European oyster farmers. The life cycle of this Haplosporidia protozoan Bonamia ostreae is unknown, it is not dttectable during the five mon th latent period. Because of the Jack of sensibility of reference techniques, histology and tissue smear, further use of PCR assays or HCM-CC, in particular, is recommended. Analysis of data collected in France from 1989 to 2004 shows the absence of simple prediction methods and an apparent cyclicity of the disease. Transfer restriction and control of boat hulls can protect uninfected areas. Reducing stress and density, commercialising earlier can limit losses in infected areas. The...

Optimization of a survey using spatially balanced sampling: a single-year application of clam monitoring in the Arcachon Bay (SW France)
Provedor de dados: 5
Autores: Kermorvant, Claire; Caill-milly, Nathalie; D'Amico, Frank; Bru, Noelle; Sanchez, Florence; Lissardy, Muriel; Brown, Jennifer.
Bivalves are important components of benthic marine and freshwater ecosystems throughout the world. One of the most exploited bivalves used for human consumption is manila clam (Venerupis philippinarum). In Arcachon Bay (SW France), commercial fishers and scientists have developed a monitoring survey to estimate clam stocks to assist in implementing a sustainable management strategy. The survey design that is currently used is based on standard stratified random sampling (StRS). The survey has been undertaken every 2 years since 2006. Each survey costs approximately (sic) 50 000, with funding provided by similar to 20% of the commercial fishers. The survey is quite expensive, given that this resource is managed mostly at a regional level. In 2016 for...

Bilan des perturbations phytoplanctoniques observées sur les côtes françaises en 1986
Provedor de dados: 5
Autores: Belin, Catherine; Berthome, Jean-paul.
In 1986, 23 discolored waters were observed ; dinoflagellates often were the cause of them. Many developments of Prorocentrum minimum occured ; two of them were associated with shel1fishes mortalities. At contrary, other species which are suspected to be toxic for shellfishes, as Gyrodinium aureolum and Gyrodinium spirale, have not been associated with mortalities, although they have been observed in several areas.  The developments of Dinophysis (cf. acuminata or sacculus) caused provisional prohibitions of shellfishes selling, especially in the south of Brittany. Another specie was also implicated in toxicities : Prorocentrum lima. Human intoxications and economic consequences were rather important.

Nutrients levels of marine water along the North of France coastline are growing-up. They have a good chance to become a problem in the future. Since 1992, a network of three radial lines is sampled at regular interval to supervise on long term : 1. Parameters levels that show the environment quality (temperature, salinity, turbidity,total suspended matters, organic suspended matters, chlorophyll, phaeopigments, phytoplankton). 2. Nutrients concentrations ( ammonia, nitrite, nitrate, phosphate, silicate) that enrich the environment , and may be responsable of its deterioration. The report shows the results of the first three years survey. I t strikes a correlation between the tested parameters and takes stock of the present situation.

The French anchovy fishery
Provedor de dados: 5
Autores: Duhamel, Erwan; Biseau, Alain; Masse, Jacques; Villalobos, Hector.
The french fishery of anchovy is divided in two groups defined by gears : purse seine and pelagic trawl. The average length of these vessels is about 20m. This fleet is very opportunistic : all trawlers are using several trawls during the year, to catch sometimes bass, tuna, hake, or scampi, and purse seine are mainly fishing sardine. Each year, the main anchovy catches are provided by pair trawlers. Purse seiners operate often in coastal areas (&lt;10 nautical miles); trawlers may operate until 50 nautical miles offshore but are banned inside the three miles coastal zone. The pair trawlers may operate from Basque country to western Channel according to fish availability. Purse seiners usually stay around their home harbour.

The research programme developed within in the framework of the project study of the Paluel site allowed us to highlight, near the drainage channel of the Durdent, a sea trout fishery using fixed nets in the area of the swaying of the tides. This activity, very much in use in the eastern English Channel and along the southern shoreline of the North Sea, not only for catching certain amphibiotic species but also species that are strictly of the sea, represents a sizeable cause of the mortality rate for salmonid populations during their coastal migrations. The studies begun on this fishery in 1980 have as their goal to assess the size of the salmonid catches near the site, especially of sea trout, and to acquire more complete knowledge of the catch, biology...

The study undertaken during the 1994-1998 planning contract on the Breton fishing fleet made it possible to underscore the size of the economic activity in regional territorial waters: More than 85% of the ships work there. This space, which is a matter of national sovereignty, is mainly managed at the regional level. To clarify the paths that may need to be taken, it seemed opportune to us to identify spatially the coastal fisheries, as well as the main current problems of planning.  The fishing zones were mapped. This work required special surveys of the local fishing committees, because it could not be done from existing fishing statistics. The surveys allowed us to approach the localization of the various trades' fishing zones on maps at 1/50,000, as...

Whatever their geographical or political point of view, Sea and coastal strategies highlight an “abyssal need” for knowledge and frequently call for a reinforcement and a better valorization of research in Marine Sciences and Technologies (MST). But, when a French public research resources inventory is needed, in the perspective of constructing a consistent action plan, we lack a framework to define thematic and disciplinary perimeter to be taken into account, to identify available data, to choose practical evaluation or estimation methods. The following study is a proposal to answer these questions. The methodology is mainly based on data collected by French High Council for Evaluation of Research and Higher Education (Hcéres) and completed by an inquiry....

Evaluation directe du stock de praires Venus verrucosa en rade de Brest
Provedor de dados: 5
Autores: Pitel, Mathilde; Fifas, Spyros; Berthou, Patrick.
In the 1960s, with a drop in the king scallop stock, the clam became a substitution resource with productions of over 400 tonnes. The drop in the production until the disruption of the fishery in the 1980s is the combined consequence of the increase of the fishing capacities with an unfavourable populating demographic strategy. Large deposits are fairly rare. In 7 years, only one age group, born in 1971, withstood the fishery. Many age groups of satisfactory abundance, from the end of the 80s on, combined with a total disruption of the fishery for a few years, lead to a recovery of the stock with fishing levels equivalent (today) to those of the 1950s. The clam, though less iconic than the king scallop in the local context, has now been for a number of...

Autores: Trenkel, Verena; Pinnegar, John; Rochet, Marie-joelle; Rackham, Brian.
Choice of sampling method and survey period can have an important impact on the perception of the structure and dynamics of an ecological community. For the Celtic Sea fish assemblage we compared data obtained by three different trawl surveys: an autumn groundfish survey with a GOV trawl, and a spring and an autumn groundfish survey, both carried out with a Portuguese high-headline trawl. Time-series of abundance estimates were not consistent among surveys for all species and were generally very noisy. An analysis of variance components showed that the sampling method contributed more to the variance in abundance estimates compared to survey period, interannual variability, or even sampling variance. Overall community assessments based on indicators such...

INTRODUCTION:  The Dover Strait (Figure 1) connects the North Sea to the English Channel. Here, northern France and South-East England are at their closest. This narrow corridor, one of the world's busiest straits for maritime shipping, is a key economic area for numerous activities, such as leisure and tourism, international ports and shipping, plus the exploitation of living or abiotic marine resources. This area is a significant resource for fisheries because many commercial fish species are abundant there, but also because of the presence of nursery and spawning areas and migratory routes linked to specific environmental characteristics. The vulnerability of these resources, which are subjected to strong anthropogenic pressures, has brought together...

Autores: Desaunay, Yves; Guerault, Daniel.
A beam trawl survey of the Bay of Vilaine was conducted from 1981 to 1997. Changes in the commercial fish community were analyzed by comparing the characteristics at the year and decadal scales. The community structure and nursery function of the Bay were steady during the period. However, specific richness, assiduity and distribution indices demonstrated a reduction in the second decade. The global abundance fell from 105.8 ind.ha-1 to 31.3 ind.ha-1. This trend was less marked for the external more marine stratum, which exhibited the lowest densities. The results are discussed in terms of ecological meaning of such a community, compared with the overall demersal fish community. The reasons of the decrease are questioned regarding nursery habitat, local...

Autores: Kermorvant, Claire; Coube, Sébastien; D’amico, Frank; Bru, Noëlle; Caill-milly, Nathalie.
Issues on sampling procedure definition led numerous study results to be biased and object of controversy. Choosing relevant sampling design and number of samples is a difficult task when wanted to set up or optimize a survey. The survey design choice is very important to avoid bias and increase the survey cost-efficiency. It can have a strong effect on the sample size needed to achieve some targeted accuracy on results. And on the final cost of the procedure. The sequential process we expose here melt design based and model based sampling theories. Its objectives is helping practitioners defining a sampling design and a number of samples for their survey when inference to the whole population is wanted. The main idea is to mathematically reconstruct the...

A fisrt survey designed to estimate the impact of the fishery on the multispecific population of the slope has been carried out from June 26th to July 20th 1996 on board of the French R/V Thalassa. This survey took place West of Scotland, between 55 degrees and 57 degrees of latitude North, on an area from where data before exploitation were available and where fishing activity was intensive since the 90's. On this area, the analysis of the species composition by haul only showed that the fish assemblage was structured according to depth. Such a conclusion was not new. However, the positioning of the hauls on two smaller sectors characterized by different slopes and bottoms, and probably by a lesser fishing intensity on the one with rougher bottom did not...

Sardine series in PELGAS surveys : PELGAS 2000 to 2005
Provedor de dados: 5
Autores: Masse, Jacques; Duhamel, Erwan; Delaunay, Damien.
Survey data from 2000 to 2004 were used to analyse whether sardine show a preferential distribution in relation to bottom depth and/or latitude. For this analysis, four strata were considered; North or South of latitude 46°N (separating VIIIa and VIIIb) and bottom depths deeper or shallower than 110m. Sardine length distributions are plotted as the proportion of small (&lt; 18.5 cm) or big (larger than 18.5 cm) fish on the samples over the years. This division was chosen to take into account the bimodal structure of sardine length distributions (usually with a "valley" at 18.5 cm fish length). Small fish (mainly 1 year old) are generally found close to the coast and preferentially in the southern part. The year 2003 is different to the others but this year...

Trophic level (TL)-based indicators have been widely used to examine fishing impacts in aquatic ecosystems and the induced biodiversity changes. However, much debate has ensued regarding discrepancies and challenges arising from the use of landings data from commercial fisheries to calculate TL indicators. Subsequent studies have started to examine survey-based and model-based indicators. In this paper, we undertake an extensive evaluation of a variety of TL indicators across 9 well-studied marine ecosystems by making use of model- as well as surveyand catch-based TL indicators. Using detailed regional information and data on fishing history, fishing intensity, and environmental conditions, we evaluate how well TL indicators are capturing fishing effects...

An acoustic survey was carried out in the bay of Biscay from May 3rd  to June 1st  on board the French research vessel Thalassa. The objective of PELGAS05 survey was to study the abundance and distribution of pelagic fish in the Bay of Biscay. The target species were mainly anchovy and sardine and were considered in a multi-specific context. The results have to be used during ICES working groups in charge of the assessment of sardine, anchovy, mackerel and horse mackerel and in the frame of the Ifremer fisheries ecology program "resources variability".

The annual activity calendars of the 2,000 Breton fishing boats registered in the national POP file (with the exception of seafaring ships: 35 ocean-going tuna boats and 2 ships from Saint-Malo) were reconstituted for the year 1994 through surveys of the owners of these ships. Resorting to this method was necessary to overcome the weak statistical coverage of coastal fishing activity that is practiced within the 12 miles of territorial waters. This collection of information made it possible to build a database that contains, for each boat, the various trades practiced during the year 1994 and, if applicable, the periods of inactivity. By "trade", we mean the putting to use of a fishing vessel in order to catch one or several target species, in a given...

Provedor de dados: 82
Autores: Barcellos,Aline; Schmidt,Letícia S.; Brailovsky,Harry.
The coreoid fauna from Neotropics is poorly known, especially in terms of community studies. Aiming at contributing to this knowledge, a two-year study was carried out at Parque Estadual do Turvo, Municipality of Derrubadas, state of Rio Grande do Sul, Brazil, to evaluate the composition, abundance and species richness of Coreoidea. Samplings were conducted in the springs of 2003 and 2004 (October), and autumns of 2004 and 2005 (May), using beating tray method, along two trails of the park. Sampling effort (hours X collectors) totaled 153h. A total of 282 individuals of Coreoidea were collected, distributed in 28 species of Alydidae, Coreidae and Rhopalidae. The most abundant species was the coreid Cebrenis supina Brailovsky, representing 16% of the...

An improved bait method for collecting hymenoptera, especially social wasps (Vespidae: Polistinae)
Provedor de dados: 82
Autores: Noll,Fernando B; Gomes,Bruno.
In this work, an alternative method for the capture of neotropical social wasps is described, which may supplement or replace the procedures commonly used in wasp surveys. The method was tested in a seasonal semideciduous forest in the northwest of São Paulo State, collecting a larger number of species and a greater abundance of social wasps and of other Hymenoptera than other methods also used in the same area, namely Malaise traps, bottle traps and meat baits. The proposed method was adapted from Wille (1962) who used an attractive solution based on water and honey for bee attraction. In here, the attractive solution was based on water, salt and crystal sugar, and was effective in attracting bees and solitary wasps, but mainly social wasps, which is the...

Insecticide resistance in populations of the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), from the state of Pernambuco, Brazil
Provedor de dados: 82
Autores: Santos,VC; Siqueira,HAA de; Silva,JE da; Farias,MJDC de.
The diamondback moth Plutella xylostella (L.) has a great economic importance in Brassicaceae crops in many parts of the world. Recurrent infestations of this pest in growing areas of Pernambuco state, Brazil, have led farmers to frequently spray their crops with insecticides. However, control failures by several insecticides have been alleged by farmers. The objective of this study was to check whether resistance to insecticides could explain these control failures in P. xylostella. Populations of P. xylostella from Pernambuco were collected between January and April 2009. The resistance ratios of P. xylostella populations were compared among five different active ingredients: abamectin, methomyl, lufenuron, indoxacarb, and diafenthiuron by leaf dipping...

Autores: Abreu,Raimunda; Ronchi-Teles,Beatriz; Monné,Miguel; Vianez,Basílio.
The occurrence of Cerambycidae (Lamiinae) was evaluated in trunk and branch samples of cardeiro (Scleronema micranthum), a forest species from the Central Amazon. Samples were exposed to biodegradation for 24 months on the forest soil, during which adults and larvae were collected and their attack was evaluated. From a total of 643 cerambycids collected, 606 were immatures and 37 were adults. Two species of Acanthoderini, Psapharochrus longispinis (Bates) (17 specimens) and Steirastoma melanogenys White (17 specimens) were collected, as well as one species of Onciderini, Jamesia globifera (Fabricius) (three specimens). Most larvae were found in the bark of trunks and branches, while pupae and adults were mainly found in the sapwood.

Surveying neotropical social wasps: an evaluation of methods in the "Ferreira Penna" research station (ECFPn), in Caxiuanã, PA, Brazil (Hym., Vespidae, Polistinae)
Provedor de dados: 84
Autores: Silveira,Orlando Tobias.
A survey of social wasps was made in the area of the "Ferreira Penna" Research Station (ECFPn) in Caxiuanã, PA, Brazil. Traditional collecting methods as the use of Malaise traps and the search for individuals and colonies of wasps along trails in the forest and by river margins, were applied in a more systematized fashion. Seventy-nine species belonging to 18 genera were discovered within a discontinuous period of 52 days of collecting. Angiopolybia pallens, Polybia liliacea, and several Agelaia species were the most frequently collected species. Active search for wasps in the forest and by river margins was far more efficient than Malaise traps regarding the discovery of polistine species.

ABSTRACT To test resistance status of Phalaris minor (littleseed canary grass) to fenoxaprop-P-ethyl in Pakistan, a field survey was conducted during 2014. Uncontrolled P. minor plants were selected for seed collection from wheat fields where fenoxaprop-P-ethyl was used to control P. minor. Seeds were collected from eight different locations near Fasialabad, Pakistan. Susceptible plants were also selected near Faisalabad having no history of fenoxaprop-P-ethyluse for comparison. These seeds were grown in pots for resistance confirmation using completely randomized design with factorial arrangement having four replicates. Four doses of fenoxaprop-P-ethylcontrol (0X), 46.9 (0.5X), 93.7 (1X) and 187 (2X) g a.i. ha-1 were sprayed at 3 to 4 leaf stage of P....

It has been a long time since we have seen a cost of production study for horticultural crops, notably processing vegetable crops, in New York State; however, research in this arena is completed in many other states and continues to offer useful information to industry stakeholders. This type of information is especially important in the processing vegetable sector in New York State as it has seen substantial acreage decreases in recent years. Here we develop a survey to collect data from processing vegetable growers in New York State and use it to calculate costs and net returns of producing snap beans and green peas. Our results indicate that the average cost of producing snap beans in New York State is $568 per acre and is $563 per acre for green peas;...

Vulnerability to risk among small farmers in Tajikistan: results of a 2011 survey
Provedor de dados: 31
Autores: Lerman,   Zvi; Wolfgramm,   Bettina.
Tajikistan is judged to be highly vulnerable to risk, including food insecurity risks and climate change risks. By some vulnerability measures it is the most vulnerable among all 28 countries in the World Bank’s Europe and Central Asia Region – ECA (World Bank 2009). The rural population, with its relatively high incidence of poverty, is particularly vulnerable. The Pilot Program for Climate Resilience (PPCR) in Tajikistan (2011) provided an opportunity to conduct a farm-level survey with the objective of assessing various dimensions of rural population’s vulnerability to risk and their perception of constraints to farming operations and livelihoods. The survey should be accordingly referred to as the 2011 PPCR survey. The rural population in Tajikistan is...

An understanding of the responsiveness of food demand to price changes is critical to decision making in the area of food policy. The estimation of these elasticities is difficult in developing countries, such as Fiji, due to a lack of reliable data. We review the existing data on food demand elasticities in Fiji and examine alternative approaches to their estimation given the data constraints present. We use a stated preference approach to provide a new set of estimates of food demand elasticities for Fiji using cross section data.

More Americans are eating hamburgers more well-done than in the past, according to national surveys. This change reduced the risk of E. coli O157:H7 infection by an estimated 4.6 percent and reduced associated medical costs and productivity losses by an estimated $7.4 million annually. In a 1996 survey, respondents who were more concerned about the risk of foodborne illness cooked and ordered hamburgers more well-done than those who were less concerned. However, respondents who strongly preferred hamburgers less well-done cooked and ordered them that way, even after accounting for their concern about the risk of illness.

The concept of food insecurity at the household and individual levels has been an area of extensive research in the late 1980s by individual researchers and public agencies. This work culminated in the development of the US Food Security Survey Module (FSSM), which is now seem to be the  standard methodology of determining household food’s security status, at least in countries with developed economies. One of the purposes of this study is to adapt the FSSM in the context of a less developed economy, and thereby assess the prevalence of food insecurity and hunger. The module was administered as a pilot in a household survey of 110 low-income families in the Dominican Republic. This study found that 93% of the respondent were food-insecure, some more so...

The Implications of Skewed Risk Perception for a Dutch Coastal Land Market: Insights from an Agent-Based Computational Economics Model
Provedor de dados: 31
Autores: Filatova,   Tatiana; Parker,   Dawn Cassandra; van der Veen,   Anne.
Dutch coastal land markets are characterized by high amenity values but are threatened by potential coastal hazards, leading to high potential damage costs from flooding. Yet, Dutch residents generally perceive low or no flood risk. Using an agent-based land market model and Dutch survey data on risk perceptions and location preferences, this paper explores the patterns of land development and land rents produced by buyers with low, highly skewed risk perceptions. We find that, compared to representative agent and uniform risk perception models, the skewed risk perception distribution produces substantially more, high-valued development in risky coastal zones, potentially creating economically significant risks triggered by the current Dutch flood...

A multinomial logit is utilized to model the choice of whether to purchase yield or revenue insurance using subjectively elicited survey data. Our results indicate that the demand for crop insurance is inelastic (-0.40), consistent with most earlier yield elasticity estimates, but the elasticity for choices between yield and revenue insurance is found to be relatively more elastic (-0.88).

The 1998 Survey of Small Business Finances provides robust information on the financing of small businesses including an overview of their firm's organization, financial characteristics, and credit use.  Information from the survey is used in this study to compare the financial characteristics of urban and rural small businesses.  Overall, rural small businesses have very similar financial characteristics, access to technology and financial services, sources of financial capital, and creditworthiness when compared to urban small businesses.  Nonparametric rank order statistical methods were required when comparing dollar values of urban and rural small businesses because normality assumptions were violated due to the high concentration of small firms.

Corporate Social Responsibility in Agribusiness: Empirical Findings from Germany
Provedor de dados: 31
Autores: Heyder,   Matthias; Theuvsen,   Ludwig.
The social responsibility of businesses has developed into a highly debated issue in recent years. Especially in agribusiness, recent scandals as well as information asymmetries concerning food production have led to high external pressure on firms from the wider public. Being confronted with a variety of stakeholder goals and relationships, it could be particularly advantageous for enterprises in agribusiness to pursue a corporate social responsibility (CSR) strategy. Based on a literature review, we introduce a conceptual framework that provides insights into the determinants of CSR and its effects, in particular, on the legitimacy and reputation, and finally, the performance of enterprises in agribusiness. This contingency-theoretic approach allows a...

The Use of Brands in Food Marketing - Results from a Survey of Danish Food Industry Firms
Provedor de dados: 31
Autores: Baltzer,   Kenneth; Baker,   Derek; Moller,   Anja S.
The paper tests a number of hypotheses concerning branding behaviour of the food industry found in the literature. Based on a survey of 109 Danish food industry firms conducted in 2004, three aspects of branding strategies are analysed, i) the number of brands owned by the firm, ii) the number of brands introduced by the firm during the past year and iii) the percentage of sales obtained from production under private labels. Firms' branding behaviour is related to structural variables including firm size, degree of vertical integration, value added as well as firms' views on food chain organisation and competitiveness.

Firm characteristics and managers' attitudes and opinions about pesticide safety were used to classify lawn care and landscape management firms into four categories and compare them using the logit procedure.  Survey data obtained from 223 firms was used in the empirical investigation of the adoption of the IPM techniques.  Results showed the need for continued transfer of new technology to independently owned firms, multidisciplinary assessment of IPM methods before their transfer to ascertain the economic viability of proposed methods, public investment in programs training workers in knowledge-based pesticide applications, possible assistance in obtaining capital, and investment in consumer education.

Autores: Watt,   Jean.
New Zealand has a long history of producing official statistics on agricultural, horticultural, and forestry production. Having a good population or survey frame is a key factor enabling the collection and production of quality statistics. Several population frames have been used over time for agricultural production censuses and surveys. These include land based frames, administrative registers, farmer and grower lists, and combinations of these. This paper discusses the frame currently used and earlier frames and associated challenges, including: the transition from a land based to administrative frame, coverage issues, frame updating, and issues when comparing statistics based on different frames. The paper discusses frames used for the production of...

HUNGARIAN LAND OWNERSHIP PATTERNS AND POSSIBLE FUTURE SOLUTIONS ACCORDING TO THE STAKEHOLDERS' VIEW

Autores: Feher,   Istvan; Madarasz,   Istvan.
Following the rent free land use by large-scale farms under the communist regime, it was hoped that the restoration of private ownership of land and land-auctions would revive the land market and that the market would establish real land prices and farm rents in Central and Eastern Europe. In the majority of the former socialist countries of Central Europe the primary land privatization method was restitution to pre-war owners. In Hungary, a mixture of (i) restitution, (ii) division of cooperatively farmed land among cooperatives’ workers and the (iii) sale of land to individuals were applied in land privatization.  In lack of a well-functioning land market and realistic land prices (i.e. prices set by the marketable values of a given parcel), prohibition...

The earthquake that hit Haiti in the beginning of 2010 led to tremendous international solidarity in the recovery effort. Despite the tons of aid sent to Haiti, relatively little is known about the effectiveness of the aid or about the continuing needs of the Haitians. Using data collected from in-person surveys with over 1,000 Haitians, we sought to quantify some of the impacts of the earthquake while determining people’s relative preferences for food and other basic needs in the aftermath of the Haiti’s earthquake. The results indicate that almost two-thirds of Haitians lost a friend in the earthquake, and nearly half lost a family member.  People report spending more on food in the aftermath of the earthquake, and the level of food aid received does not...

The role that information technology plays in today’s business activities has led to an  increase in firms using and/or deploying e-markets online. This development undoubtedly affects the agri-food sector, since a large number of agricultural firms are demonstrating or are expected to demonstrate e-commerce activities. This paper aims to provide an overview of the current status of agricultural e-markets in Greece, by presenting results from an analysis of 100 cases. Results indicate that Greek e-markets may  still have a rather low degree of sophistication, but they demonstrate a strong B2B orientation, as well as an outreach for international customer bases.

Autores: Pieniadz,   Agata; Renner,   Swetlana; Rathmann,   Christoph; Glauben,   Thomas; Loy,   Jens-Peter.
During recent years, the number of farms able to generate satisfactory income from agricultural production has continuously decreased in advanced economies. The main reasons are the implementation of the Common Agricultural Policy of 1992 and the increasing capitalization of the primary sector. The relevance of income diversification and interest in various development paths of rural households have, therefore, been renewed in political-economic debates in those countries. The aim of this study is to identify factors that determine income diversification in Germany. An econometric model has been estimated based on a comprehensive survey’s data. The results show that the main economic incentive for farm diversification is the expected income increase or...

A survey of 139 men and 123 women in four communities bordering Los Haitises National Park in the Dominican Republic took place in late 1992.  The survey followed a presidential decree ordering the army to clear the forest of people and cattle and to resettle a number of villages.  The survey found that people admitted using the forest for firewood and cash crop cultivation.  However, they were aware of the need to conserve the forest and expressed willingness to compromise on its use.  They were less aware of park boundaries and did not understand the concept of a national park.  Villagers welcomed rapid population growth, and women favor (and have) large families despite high rates of sterilization.  Nearly everyone opposed resettlement and favored...

Traceability Adoption by Specialty Crop Producers in California
Provedor de dados: 31
Autores: Stuller,   Zachary J.; Rickard,   Bradley J.
Surveys were sent to specialty crop producers in California, predominantly grower-packer-shippers, during the first half of 2006 to better understand the motives for traceability adoption. The questions in our survey allowed respondents to consider the benefits of tracing. A representative tracing system for melons was developed and costs for the system were collected from industry sources. Values were assigned to the benefits of traceability based on the cost of the representative system, responses collected in our survey, and using Borda’s rule. Results suggest that litigation concerns and firm reputation are the key drivers for maintaining traceability.

The Ancillary Carbon Benefits of SO2 Reductions from a Small-Boiler Policy in Taiyuan, PRC
Provedor de dados: 31

To reduce carbon emissions worldwide, it makes sense to consider the possibility of developed countries paying for carbon reductions in developing countries. Developing countries may be interested in such activities if the ancillary air pollution benefits are large. This paper reports on an RFF survey of the emissions benefits (and costs) of reducing sulfur dioxide (SO2) emissions from small, coal-burning boilers in Taiyuan, an industrial, northern Chinese city that recently banned uncontrolled coal combustion in certain small boilers in the downtown area. We find significant carbon benefits in percentage terms-on the order of 50% to 95% reduction-associated with this SO2 control policy, with large reduction potential elsewhere in Taiyuan and China.

In this paper we report on the results of a telephone survey conducted in Southern California during August and September 1996. The purpose of the survey was to inform respondents about a set of rather complex pricing policies designed to reduce motor vehicle emissions and to estimate respondent support for those policies. After receiving extensive information about these policies, respondents were polled on whether they would support, i.e., vote for, any or all of these options. The pollution fee survey elicited support for a plan that levied a fee on vehicles in the region, depending on the vehicle's emissions per mile and on the miles driven. The sample was then split in two, with half the respondents being told that a portion of the revenues would be...

IMPACTS OF POLICY REFORM ON HILL FARM INCOMES IN UK
Provedor de dados: 31
Autores: Acs,   Szvetlana; Dallimer,   Martin; Hanley,   Nick; Armsworth,   Paul R.
Hill farming in UK is experiencing very difficult economic circumstances and many farmers rely on subsidies provided by the government for a large fraction of their income. The Peak District National Park is used as a case study to examine how farmers might respond to current policy changes – in particular, the move from area- and headage-based payments to the Single Farm Payment. The objective of this paper is thus to develop production models that predict how farmers will respond to changing policy framework conditions. For this purpose socio-economic surveys were carried out on 44 sample farms. Based on these surveys six representative farm linear programming models was developed, which represent typical farm types in the uplands in the Peak District....

Characteristics of environmentally conscious production behaviour in agricultural waste management
Provedor de dados: 31
Autores: Kormosne-Koch,   Krisztina.
When measuring environmentally conscious behaviour and determining its variables, focus often lies only on consumers, but environmental conservation requires not only the consumers’ but also the producers’ input. After defining environmentally conscious behaviour, I utilized the market research method to determine how participating in agri-environmental programs and subsidies affects producers’ environmental consciousness and waste management behaviour. The research result indicates that participation in agri-environmental programs develops producers’ environmental sensitivity, and improves their environmentally conscious behaviour, and this even holds true for waste management, which is not directly not subsidized by the programs.

Key point of the survey is represented by the fact that Hungarian agricultural products had to face turbulent market conditions, heavy concurrency and sharp import competition in the European Union. A possible way of keeping or strengthening market positions is to acquaint the values of native, traditional and region-specific products (Hungaricums). Present survey focuses on analyzing the marketing possibilities of Hungarian Grey cattle and Mangalica pig along with their products. Representatives of companies producing, processing and trading mangalica and grey cattle products were interviewed and in order to define the consumers’ preferences focus group interviews were taken.

Autores: Roe,   Brian E.; Batte,   Marvin T.; Diekmann,   Florian.
Results of a nationally representative survey of US farmers link previously validated survey measures of risk aversion and interpersonal trust to farmers’ intended use of online venues for transacting used equipment.  Other factors affecting online purchase propensity includes the quality of farmers’ relationships with local equipment dealerships.  Understanding the factors that impact farmers’ use of internet market venues is crucial as rural internet penetration deepens, farm equipment needs grow more specialized and local offline markets thin.  These results may also help explain past observations of severe discounting of used farm equipment sold in online venues.

On the basis of a household typology distinguishing between net sellers, net buyers and self sufficient, the Net Benefit Ratio (NBR), defined by Deaton (1989), is used to approximate households' first order welfare variations when price change. In this paper, we discuss both the typology's criteria and the classic formula of NBR, since they are based a) on produced and consumed quantities rather than real marketed volumes and b) on a unique selling and buying price for all surveyed households. We propose another definition of a net seller and a new NBR expression allowing the analyst to take into account market failures (MF) and price seasonality (PS), which are two constancies in developing countries. We use two sets of data (from Mexico and Mali), to...

FINANCIAL ANALYSIS OF SMALL FOOD MANUFACTURING AND RETAILING BUSINESSES
Provedor de dados: 31
Autores: Gustafson,   Cole R.
The 1998 Survey of Small Business Finances provides robust information on the financing of small businesses including an overview of their firm's organization, financial characteristics, and credit use.  Information from the survey is used in this study to compare the financial characteristics of food manufacturing and retailing small businesses.  On average, both food manufacturing and food retailing small businesses had positive financial characteristics.  Although they were only marginally profitable and liquid, they were highly solvent.  Accounts receivable and inventory comprise nearly half of food manufacturers' total assets and a third of food retailers' assets.  By most financial measures, food retailers were statistically smaller than food...

What are ‘true’ loyal consumers in the food sector? Insights from an empirical study
Provedor de dados: 31
Autores: Wettstein,   Nadine; Hanf,   Jon Henrich.
Because loyal consumers are less likely to switch to competitors and because they are more tolerant to increases in price than non-loyal consumers, one of the main aims of firms is the “generation” of loyal consumers. But what is consumer loyalty? The marketing literature emphasises that for “true loyalty” it is important to consider both consumers' purchasing pattern (i.e. repurchases) as well as the underlying attitudes of the consumers. Thus, true loyalty includes both a behavioural (purchase) component, which results in repeated purchases, and an attitudinal component, which results in a dispositional commitment to a product, a brand, or a company, and associates a unique value to it. However, considering the characteristics of food products and the...

Grower perceptions of the impact of protein premiums and discounts for wheat
Provedor de dados: 31
Autores: Petersen,   Elizabeth H.; Fraser,   Rob W.
This paper presents results of a survey of Western Australian wheat growers designed to elicit perceptions of the impact of protein premiums and discounts for wheat on income, utility and off-farm risk management. The results indicate that a grower’s perception of the scheme’s impact on expected income and utility depends on that grower’s expected protein level. Additionally, growers do not perceive protein premiums and discounts to have affected the variance of income, or their willingness-to-pay for a forward contract. These latter findings are contrary to previous studies of actual rather than perceived effects. However, the perceptions of growers are understandable given that the scheme’s effect on the variance of income is small relative to its effect...

Consumer Perception of Traceability in the Meat Chain
Provedor de dados: 31
Autores: Gellynck,   Xavier; Verbeke,   Wim.
Despite growing interest in meat traceability systems, very little research has been done on consumer needs and perception of traceability. This gap is partly filled by the present study of consumer perception of meat traceability in Belgium, based on cross-sectional data collected in June 2001. Respondents are segmented, based on their subjective perception of meat quality, and differences in the perceived need for traceability systems between the various segments are investigated. Functional traceability attributes, such as organizational efficiency, chain monitoring and individual responsibility, are important to all consumers. Extensions with respect to process attributes, such as production methods, are less relevant to the general population, being...

Zusammenfassung: Der vorliegende Bericht untersucht die mittelfristigen Veränderungen in der Milchproduktion in Schweden. Im Rahmen einer web-basierten Umfrage zwischen Dezember 2009 und März 2010 wurden 273 schwedische Milcherzeuger zu künftigen Entwicklungstrends in ihrer Region und Entwicklungsperspektiven auf ihrem Betrieb befragt. Die befragten Milcherzeuger erwarten insgesamt einen weiteren Rückgang der Milchproduktion in Schweden, insbesondere in Nordschweden. Den insgesamt eher rückläufigen Erwartungen stehen die künftigen Wachstumspläne der teilnehmenden Milcherzeuger gegenüber, die sich insgesamt gut aufgestellt sehen. Da jedoch überwiegend größere und zukunftsorientierte Betriebe befragt wurden, ist diese Diskrepanz nachvollziehbar. Neben einer...

Staple Food Consumption Patterns in Urban Zambia: Results from the 2007/2008 Urban Consumption Survey
Provedor de dados: 31
Autores: Mason,   Nicole M.; Jayne,   Thomas S.
After two decades of de-urbanization, Zambia is again becoming increasingly urban. While the urban share of the population fell to 35% in 2000 due primarily to the decline of the copper industry, over half of Zambia’s people will be residing in urban areas by 2040. Given this urbanization trajectory, to be effective, policies to promote smallholder agriculture and improved urban food marketing system performance in Zambia will need to take into consideration the demand patterns of urban food consumers. Urban consumption patterns will increasingly determine the opportunities available to small-scale farmers. Accurate information on urban consumer preferences can also help identify key leverage points and investment priorities to improve the performance of...

Análise do grau de restritividade de exigências técnicas às exportações brasileiras
Provedor de dados: 31
Autores: Faria,   Rosane Nunes de; Burnquist,   Heloisa Lee.
The objective of this investigation was to evaluate to what degree technical requirements restrict Brazilian exports, based on a survey applied to 77 firms. The variables represented six types of technical measures that are usually imposed upon exported products. To facilitate the interpretation of the results, factorial analysis was used to reduce the number of variables involved. This allowed the construction of two indicators of the degree of restrictiveness of the technical barriers focused by the study. These were an indicator of requirements of technical specification (ITS) and an indicator for information and label requirements (IIL). Descriptive statistics and paired t test showed that the firms surveyed considered the ITS more restrictive to their...

NON-TARIFF TRADE BARRIERS IN AGRICULTURE
Provedor de dados: 31
Autores: Mattson,   Jeremy W.; Koo,   Won W.; Taylor,   Richard D.
As trade agreements lower tariff rates throughout the world, other barriers to trade emerge.  These non-tariff barriers can be just as troublesome for exporting companies.  Non-tariff barriers include technical measures, customs rules and procedures, transport regulations or costs, lack of knowledge of regional markets, and import policies.  The objective of this study is to identify non-tariff barriers faced by U.S., and more specifically North Dakota, exporting businesses, especially those involved in agriculture, and to identify difficulties involved in exporting products.  A survey of North Dakota businesses is conducted to identify important trade barriers.  Phytosanitary regulations and railroad problems are two frustrating issues that create...

Provedor de dados: 89
Autores: Fiorentin,L; Mores,MAZ; Trevisol,IM; Antunes,SC; Costa,JLA; Soncini,RA; Vieira,ND.
There is a need for a better understanding of the epidemiology of Mycoplasma synoviae (MS) infection in broiler breeders in Brazil. Many features of the infection remain unrecognizable, because there are no clinical signs of the disease. A detailed testing was performed at each 6 to 8 weeks in three MS-free flocks introduced in farms with endemic MS infection for a follow-up epidemiological study. Every flock was monitored by polymerase chain reaction (PCR), by serum plate agglutination (SPA) and hemagglutination inhibition (HI) for serology studies, and isolation of mycoplasmas from tracheal swabs. PCR was found to be the most sensitive test, detecting early MS infection. Serology was positive in less than 50% of the sera and MS was isolated only between...

Bait traps remain attractive to euglossine bees even after two weeks: a report from Brazilian Atlantic forest
Provedor de dados: 92
Autores: Coswosk,Judson Albino; Soares,Elaine Della Giustina; Faria,Luiz R.R.
ABSTRACT Bait traps are effective and commonly used method in the studies of orchid bees. Important questions in the context of this method, including those related to bait dispersion, how long baits remain attractive, the distance from which males are supposed to be attracted to lures and so on, are still open subjects. Data on the attractiveness of bait traps that have remained in the field during two weeks in a large Atlantic forest preserve are presented. Four main results emerge from the data: (i) the abundance of specimens collected per day decreased in all the attractants as the traps were left on the field; (ii) despite this decrease, the absolute number of individuals collected after eight and fifteen days is remarkably, mostly in eugenol and...

ABSTRACT Carlos Botelho State Park (PECB) is a large remnant of Atlantic Forest in Southeastern Brazil, with more than 37,000 ha. As its bat fauna is still unknown, we performed the first bat survey on PECB, to provide data on the distribution, natural history and taxonomy of the species. Fieldwork was conducted monthly, from October 2016 to September 2017. Captures were made using ground-level mist-nets (39600 m2.h), canopy mist-nets (2017.5 m2.h) and searches for roosts (42 hours).We captured 412 bats from 34 species of Phyllostomidae, Molossidae and Vespertilionidae. A total of 11 species were captured only in ground-level mist-nets, five in canopy mist-nets, and seven in roosts. Dermanura cinerea Gervais, 1856, Eptesicus taddeii Miranda, Bernardi &amp;...

How much effort should be employed for surveying a low-diversity Amazonian mammal assemblage using line-transects?
Provedor de dados: 103
Autores: Mourthé,Ítalo.
Line-transect surveys are commonly used for sampling large mammals, but estimates of the effort needed to reliably surveying low-diversity assemblages of mammals are scarce. Using data from line-transects and species accumulation curves, I examined whether or not a sampling effort previously suggested to survey mammals elsewhere (ca. 85-100 km) would be satisfactory for surveying a low-diversity assemblage of large mammals in the Rio Negro basin in northern Amazonia. In total, 14 mammals were recorded after an accumulated effort of 690 km walked. The desired threshold of completeness was only achieved in one of six transects after an average effort of 115 km surveyed. Considering the entire landscape (all transects pooled), survey completeness was reached...

Selective breeding of Arabian and Thoroughbred racehorses in Algeria: perceptions, objectives and practices of owners-breeders
Provedor de dados: 96
Autores: Tennah,Safia; Farnir,Frédéric; Kafidi,Nacerredine; Nsangou,Ibrahim Njikam; Leroy,Pascal; Antoine-Moussiaux,Nicolas.
This survey, conducted with 461 racehorse owners-breeders in Algeria between 2009 and 2011, investigates their perceptions, objectives and practices regarding selective breeding. Racehorse breeding is a full-time professional activity for a third of interviewees. The holdings are small-sized with 77% owning one or two mares. The regular practice of mating is here used to categorize breeders according to their degree of professionalization (38.4% professional vs. 61.6% occasional breeders). Experience in the sector was also used to classify breeders, considering as "junior" the breeders under 10 years experience (38.8%) and as "senior" those above 10 years (61.2%). More than professionalization, experience shows a significant impact on practices and...

ABSTRACT The objective of this study was to develop a feedlot beef cattle calculation model and production cost analysis and, from the results obtained, devise a production cost index. A case study was conducted to understand the characteristics of the productive processes of a commercial feedlot. Then, based on the Economic Theory, cost items of the farm under analysis were identified and transferred to a spreadsheet. The survey included ten feedlot farmers from the state of São Paulo and other nine from the state of Goiás and was carried out to determine representative properties, and prices of items used were monitored. Production costs of each farm were calculated, and theoretical concepts of index numbers were used to devise the feedlot cattle...

The aim of this study was to investigate consumers' decision-making process, attitudes and values towards organic food throughout the employment of the Theory of Planned Behaviour, adapting the methodology from a European project. 450 consumers were interviewed at supermarkets and farmers' markets in Porto Alegre, Brazil. Results indicate a high penetration level and very positive attitude towards organic products. Organics are believed to be healthier, tastier, more natural and environmental friendly, although being less attractive and more expensive than conventional food. Respondents from the farmers' market represent a specific segment whose values are more oriented toward society. The findings showed an alignment between positive attitude and...

Boll weevil within season and off-season activity monitored using a pheromone-and-glue reusable tube trap
Provedor de dados: 63
Autores: Neves,Robério Carlos dos Santos; Torres,Jorge Braz; Barros,Eduardo Moreira; Vivan,Lúcia Madalena.
ABSTRACT: The boll weevil colonizes cotton fields as early as cotton squaring, causing significant losses due to feeding and protected development inside fruiting structures throughout crop phenology. Successful control depends on control of adults and their accurate detection when they colonize the crops. The commercial trap and boll weevil attract-and-control tubes (BWACT) are the only available tools to monitor and attract-and-kill boll weevil, despite limitation in efficacy, and insecticide in BWACT is not allowed in organic production. A grandlure-and-glue reusable and insecticide-free tube (GGT) made with polyvinyl chloride tube, smeared with entomological glue, and lured with pheromone was tested to detect boll weevil activity across various...

Survey and evaluation on rice seed quality in Mae Hong Son Province were conducted during 2009-2010. The survey aimed to investigate farmer’s practices on rice seed production and uses, seed demand and problems as well as to monitor farmers after using good seed. Three groups of people were interviewed consisted of seed producers and  sellers, farmers who used their own seed and farmers who used good seed. The result showed that most of the seed samples were unqualified as compared to the Rice Department seed standard. The major problems found were seed impurity and mixed of foreign materials. There was only one group of farmers producing and selling rice seed in Mae Hong Son and they were faced with problems on revolving fund and group management. The...

Thrips tabaci Lind.: é realmente uma praga do algodoeiro no Brasil?
Provedor de dados: 44
Autores: Monteiro,Renata C.; Zucchi,Roberto A.; Mound,Laurence A.
The occurence of Thrips tabaci Lind. on cotton (Gossypium hirsutum L.) was investigated. In the Brazilian literature T. tabaci has been mentioned as a common early season phytophagous pest of cotton. However, there are no references to collections (voucher specimens) or to identification methods that can clarify these records. In contrast, among many samples of thrips collected between 1992 and 1996 (mostly in 1995) on cotton, in 30 counties from five states and four geographic regions, not a single specimen was found. If T. tabaci occurs commonly on this crop in Brazil, even at relatively low populations, then at least some individuals should have been collected in this survey. Most of the thrips specimens taken from cotton were Frankliniella schultzei...

Autores: Calaça,Analice; Fachi,Marluci; Silva,Diego Afonso; Oliveira,Seixas Rezende; Melo,Fabiano Rodrigues de.
Abstract: Habitat fragmentation is one of the principal causes of the decline of species worldwide, and the Brazilian Atlantic Forest and Cerrado savanna biomes are among the most severely affected by this process. While highly fragmented, remnants of Atlantic Forest can still be found within the Cerrado domain of southern Goiás, where previous studies have revealed high levels of biodiversity. To inventory the mammalian species that occur in the region, two fragments of semideciduous Atlantic Forest were sampled between 2011 and 2016, using line transect surveys and camera trapping. A total of 1016 records were obtained of 30 mammal species, of which eleven are under some threat of extinction. The species richness recorded on this study was similar to or...

Autores: Raimundi,Erikcsen Augusto; Salles,Frederico Falcão; Souza-Franco,Gilza Maria de.
The first studies of Leptophlebiidae in the Santa Catarina State, Southern Brazil, dated from 1920. Since then, not much is known about the family (even to the Order Ephemeroptera) to the State. The main goal of this study was to survey fauna of Leptophlebiidae in the Santa Catarina State based on nymphs. The material was obtained from the collection deposited at the Laboratório de Pesquisa em Ecologia e Química of the Universidade Comunitária da Região de Chapecó, besides additional specimens collected between 2008 and 2009. Occurrences were plotted in the hydrograph map of Santa Catarina State, with one map for each genus. The Leptophlebiidae nymphs were recorded in 26 aquatic environments that included small streams and rivers. We identified 24...

We present data on species composition, relative abundance and estimated densities for leaf-litter anuran amphibians from an Atlantic Forest area within the Parque Estadual do Desengano, in the state of Rio de Janeiro, Brazil, based on results of a short-term survey carried out during the winter at altitudes of 1000-1500 m. Three sampling methods were used: plot sampling, visual encounter surveys (VES; performed during the day, at the twilight, and at night), and pitfall traps. We recorded 13 species, with the direct-developer Ischnocnema parva (Girard, 1853) being the most abundant. Most frogs (ca. 90% of all individuals) sampled by VES were captured during the crepuscular and nocturnal periods. The estimated density of the local leaf-litter frog...

Autores: Magnusson,William E.; Lima,Albertina P.; Luizão,Regina; Luizão,Flávio; Costa,Flávia R. C.; Castilho,Carolina Volkmer de; Kinupp,V. F.
Our objectives were to develop a method that would be appropriate for long-term ecological studies, but that would permit rapid surveys to evaluate biotic complementarity and land-use planning in Amazonia. The Amazon basin covers about 7 million km². Therefore, even a sparse coverage, with one sample site per 10.000 km², would require about 700 sampling sites. Financial considerations limit the number of sites and investment at each site, but incomplete coverage makes evaluation of biotic complementarity difficult or impossible (Reddy &amp;amp; Dávalos 2003). Our next challenge is to install similar systems throughout Amazonia. The cost, based on modification of Al Gentry's original design is moderate (less than US$ 50.000 per site if it is not necessary...

Abstract: The Ribeirão Frutal basin is located within the upper Rio Paraná system, in the Frutal municipality, Minas Gerais State, Southeastern Brazil. Until now, there was no complete ichthyological survey published for this small basin. Therefore, here we provided a list of fish species from the Ribeirão Frutal and some of its tributaries. We found 31 species of fishes representing five orders and ten families. We identify a likely undescribed and five non-native species in the Frutal basin. Lastly, we recommend new surveys of fishes in small hydrographic basins within upper Rio Paraná system.

Autores: Silva,Cassius Schnell Palhano; Neves,Elizabeth de Souza; Benchimol,Eliezer Israel; Moraes,Danielle Ribeiro de.
Infection caused by Toxoplasma gondii, toxoplasmosis, is one of the most frequent zoonoses in the world; it normally affects both genders equally. Humans are one of several possible intermediate hosts, and the disease is oligosymptomatic in most cases. Vertical transmission is an important cause of fetal malformation and sequels in newborns. Approximately 10% of postnatal cases present multiple manifestations, ranging from low fever and mild lymphadenopathy to severe encephalitis. In moderate cases, lesions such as retinochoroiditis may emerge during acute infection or even years later. We analyzed 313 cases of toxoplasmosis from 1992 to 2004, including 261 acute cases. Most patients were women (68.1%), and 39% of these were pregnant. Among acute infection...

Autores: Landini,Fernando; Bianqui,Vanina.
In order to design and implement public policies in the context of rural development, information tends to be gathered about family farming in different Latin American countries. In contrast, scarce attention has been given to the description of rural extensionists, who are the ones supporting family farming in the field. A cross-sectional investigation was conducted between 2010 and 2012 including surveys to rural extensions working in 10 different Latin American countries, this allowing for a preliminary description of the socio-demographic profile of the respondents. The samples were incidental ranging from 19 (Bolivia) to 220 (Argentina) subjects, this implying that they were not representative. Significant statistical differences were found with...
