The landscape of Mengsong, southwest China, was biologically diverse until recently due to historical biogeographical processes overlain by the swidden-cultivation practices of the Hani who migrated there several centuries ago.  Our research sought to understand how the Hani adjusted their livelihoods to new policies, markets, and technologies, and the consequences for biodiversity conservation.  We combined landscape, plot, and household surveys, interviews, and reviews of secondary documents, to reconstruct the major changes and responses to challenges in the social&amp;#8211;ecological system over previous decades.  Significant changes from closed to open canopy of secondary-forest vegetation took place between 1965&amp;#8211;1993 and from open-canopy...

Finding a place for public participation in the policies and practices of European river basin management planning is a challenge for the authorities in the participating countries and territories. Understanding the relation between national culture, the historical and political differences in the respective countries, and their practical experience with participation is considered important to support the implementation of the EU Water Framework Directive. Knowledge and understanding of this relation is important to provide a context and basis from which new participatory practices can be designed and experiences evaluated and to identify conditions necessary for social learning. Within the context of the HarmoniCOP project, such a study was undertaken in...

Toda a problematica envolvendo a producao de borracha no Pais pode ser sumarizada em tres pontos basicos: pequena area plantada, baixos indices de producao e produtividade dos plantios nessas areas e altos custos de producao. A estes dois ultimos apectos estariam associados, entre outros: deficiencias de metodos de plantio, manejo e nutricao, efeitos depressivos no desenvolvimento da seringueira pelo ataque de pragas e doencas, pouca eficiencia das tecnicas de controle fitossanitario, pequeno numero de clones disponiveis para plantio e falta de condicoes para controle e certificacao da borracha produzida. Esse conjunto de problemas exigiu naturalmente um programa de acao coordenado, capaz de interpretar melhor o comportamento de cada fator e estabelecer...

Management of oyster and mussel culture
Provedor de dados: 5
Autores: Heral, Maurice; Drinkwaard, A.; Bohle, B.; Figueras, Antonio; Lavoie, R.; Maurer, Daniele.
The world aquaculture production (fresh and marine waters) achieved 11.1 million tonnes in 1986 (FAO, 1989). The molluscs represented 21 % of the total production. Marine aquaculture with 5.45 million tonnes reached 49% of the total production. The marine cultivated mollusc production was 2.25 million tonnes due mainly to oysters (36%), mussels (34%), clams (16%), and scallops (6%).  As the aquaculture production is clearly identified in the statistics only since 1984, the evolution of the production of oysters and mussels for the last 15 years has been analyzed with the FAO data for the total catch (fisheries and culture). By comparison of the two statistics for the same year (1986), the fisheries represented only 17% for oysters and 16% for mussels. Fig....

Autores: Byrne, Nathalie.
Since the discovery of oceanic hydrothermal vents, microbial diversity of this extreme environment was studied using both cultivation and molecular approaches. In this study the microbial diversity of active chimney from both TAG and Lucky Strike sites (Mid Atlantic Ridge) was investigated using both molecular survey and continuous enrichment culture in a bioreactor. To reproduce as close as possible environmental conditions the cultures were performed in oligotrophic conditions, in the presence of hydrogen and carbondioxide in the gas sweeping mix or using in situ sampled fluid/sea water mix as culture medium. The effect of environmental changes such as temperature and the absence or presence of sulphur was also investigated. Archaeal and Bacterial...

Traditional oyster culture in France
Provedor de dados: 5
Autores: Heral, Maurice.
The indigenous oyster of mainland France, the fiat oyster, Ostrea edulis has been part of the human diet for centuries. The Romans collected them and exported them to Rome. Although tanks for holding oysters after harvesting were in use at that time (GreIon 1978) it seems that true culture was not developed along the coast contrary to the records of Pliny the Older. It appears that oysters were already being captured on hoards off the Italian coast. The exploitation of natural stocks continued through the Middle Ages and the Renaissance. However, it was not until the 17th century that oyster culture began, first in the pools of the salt marshes of the Atlantic coast and then in specially managed ponds. Papy (1941) repeats a good description given in 1688...

The use of high rate algal ponds for the treatment of marine effluent from a recirculating fish rearing system
Provedor de dados: 5
Autores: Pagand, Pascal; Blancheton, Jean-paul; Lemoalle, J; Casellas, C.
A high rate algal pond (HRAP) system was used to treat effluent from a recirculating sea water aquaculture system in southern France. Dicentrarchus labrax L. were farmed at a high density, with effluents containing an average of 10 mg L-1 dissolved inorganic nitrogen (DIN) and 1.3 mg L-1 reactive phosphorus (RP). On a yearly basis, the algal pond removed 59% of the dissolved nitrogen and 56% of the phosphorus input, which was converted into 3.3 kg DW m(-2) algae. Green macroalgae were dominant throughout the year and the algal biomass mirrored the seasonal changes in daily irradiance and temperature. This first year study supports the possibility of treating marine aquaculture wastes using HPAPs, although conditions will have to be found to mitigate the...

Cultivating the uncultured: limits, advances and future challenges
Provedor de dados: 5
Autores: Alain, Karine; Querellou, Joel.
Since the invention of the Petri dish, there have been continuous efforts to improve efficiency in microbial cultivation. These efforts were devoted to the attainment for diverse growth conditions, simulation of in situ conditions and achievement of high-throughput rates. As a result, prokaryotes catalysing novel redox reactions as well as representatives of abundant, but not-yet cultured taxa, were isolated. Significant insights into microbial physiology have been made by studying the small number of prokaryotes already cultured. However, despite these numerous breakthroughs, microbial cultivation is still a low-throughput process. The main hindrance to cultivation is likely due to the prevailing lack of knowledge on targeted species. In this review, we...

Autores: Nival, Paul; Malara, G.
Choosing the best conditions for the cultivation of plankton in tanks is a difficult deal, which is generally solved by means of subjective estimations. A better way of looking for these conditions is the use of a mathematical model. _ We have tried to built a model that accounts for the physical and bio­logical characteristics of the tanks. The data concerning the physiological characteristics of the different group of organisms encountered are too scarce to allow all of them to be taken into account. The system studied here is composed of nutrients, phytoplankton, herbivorous copepods and rotifers to which benthic algae have been added. With the hypothesis of 3 elements (phyto - zooplankton - nutrients) it can be showed that when an equilibrium is...

Note préliminaire sur la mytiliculture dans la région Nord/Pas-de-Calais
Provedor de dados: 5
Autores: Lamolet, J.; Morell, M.
Actuellement, les principaux centres mytilicoles français se trouvent sur le littoral du Cotentin, en Baie du Mont St-Michel, dans le sud de la Bretagne, en Charente et dans l'étang de Thau ; les mollusques y sont cultivés le plus souvent sur bouchots, mais parfois aussi en suspension ou à plat. Cette production est néanmoins très insuffisante ; depuis 1976 par exemple, la France a importé (principalement des Pays-Bas), selon les années, entre 28 et 46% des moules vendues à la consommation : 26 230 T en 1976, 34 510 T en 1977 et 23 600 T en 1979. Jusqu'à présent, le littoral boulonnais ne permet de commercialiser que de faibles tonnages.

Ostreopsis cf. ovata produces palytoxin analogues including ovatoxins (OVTXs) and a putative palytoxin (p-PLTX), which can accumulate in marine organisms and may possibly lead to food intoxication. However, purified ovatoxins are not widely available and their toxicities are still unknown. The aim of this study was to improve understanding of the ecophysiology of Ostreopsis cf. ovata and its toxin production as well as to optimize the purification process for ovatoxin. During Ostreopsis blooms in 2011 and 2012 in Villefranche-sur-Mer (France, NW Mediterranean Sea), microalgae epiphytic cells and marine organisms were collected and analyzed both by LC-MS/MS and hemolysis assay. Results obtained with these two methods were comparable, suggesting ovatoxins...

Evolution of oyster aquaculture : problems and perspectives
Provedor de dados: 5
Autores: Heral, Maurice.
The total marine molluscs produced by aquaculture had increased from 1984 to 1990 by 1 000 000 tons going from 1 993 985 tons to 2 964 688 tons. The oyster production remained constant with 870 000 tons. Crassostrea gigas, the Japanese oyster, represented more than 80 % of the oyster production but high mortalities appeared in different countries connected to end of winter and summer mortalities and development of new diseases. The cultivation of Crassostrea virginica, the American oyster, was limited (80 000 tons) by the spreading of two diseases (MSX and dermo) destruction of habitat and over-exploitation. Production of the fiat oyster Ostrea eduIis was still very limited by the presence of the Bonamia diseases in a11 the countries except on...

Cyanobacterial populations that build 'kopara' microbial mats in Rangiroa, Tuamotu Archipelago, French Polynesia
Provedor de dados: 5
Autores: Richert, Laurent; Golubic, Stjepko; Le Guedes, Roland; Herve, Annie; Payr, Claude.
Cyanobacterial populations, the primary producers and builders of 'kopara' microbial mats were studied in four selected ponds along the rim of the Rangiroa Atoll, French Polynesia using a polyphasic approach. Seven isolates were maintained in uni-cyanobacterial cultures, characterized morphotypically and phylogenetically by evaluating sequences of the 16S rRNA gene of about 620 base pairs in length. Cyanobacteria in natural populations were analyzed microscopically, characterized morphotypically, and compared with cultured strains.

Ecotron - Embiez 7 - Evolution qualitative et quantitative du zooplancton dans les bassins de culture
Provedor de dados: 5
Autores: Gaudy, R.
The qualitative and quantitative evolution of a zooplanktonic population growing in a concrete tank after enrichment and production of a phytoplanktonic bloom has been followed during a time exceeding six weeks. After an initial unsteady period and a temporary peak of rotiferas, a progressive increase of organism abundance was observed, with a corresponding re­duction of their specific diversity. During the last phase of the experiment, the zooplankton community was qualitatively similar with the populations described in harbour waters or other semi-closed or closed marine spaces characterized by eutrophy and pollution. It was chiefly composed of copepods from Acartia, Tisbe and Oithona generas. The numerical density of organisms was,to a great...

Autores: Tavares-Dias,Marcos; Monteiro,Adriana Maria de Castro; Affonso,Elizabeth Gusmão; Amaral,Kárlia Dalla Santa.
Farming of native carnivore fish species has drawn attention due to their promising use in aquaculture. Among these species, tucunaré of the genus Cichla stand out, them being of high economical interest for sport fishing and Amazon's industry of ornamental fish. The present study describes the weight-length relationship (WLR), relative condition factor (Kn), red blood cell parameters, thrombocytes and leukocytes count of Cichla temensis Humboldt, 1821, farmed in central Amazon. Fish that underwent food training during fingerling culture received extruded ration containing 45% of crude protein during fattening, and had Kn with values from 0.925-1.199, which indicated good health condition during the culture. The equation obtained from the WLR was W =...

Agrifood Certification Schemes in an Intercultural Context: Theoretical Reasoning and Empirical Findings
Provedor de dados: 31
Autores: Gawron,   Jana-Christina; Theuvsen,   Ludwig.
The need for adequate systems to guarantee the quality of food products has become more and more obvious in recent years. As a consequence, not only in Germany but throughout the world, the number of certification schemes has been increasing for nearly a decade. Due to the implementation of these standards in various countries, a considerable number of contingency factors exist that may influence the effectiveness and efficiency of such schemes. These factors include the diverse political, economic and social conditions in the different countries. Numerous studies attribute a decisive role in the successful implementation of management instruments to cultural influences. Cultural conditions may differ considerably from region to region around the world....

The Right Amount of Trust
Provedor de dados: 31
Autores: Butler,   Jeffrey; Giuliano,   Paola; Guiso,   Luigi.
We investigate the relationship between individual trust and individual economic performance. We find that individual income is hump-shaped in a measure of intensity of trust beliefs. Heterogeneity of trust beliefs in the population, coupled with the tendency of individuals to extrapolate beliefs about others from their own levels of trustworthiness, could generate this non-monotonic relationship: highly trustworthy individuals tend to form overly optimistic beliefs, to assume too much social risk and to be cheated more often, ultimately performing less well than those with a belief close to the mean trustworthiness of the population. On the other hand, less trustworthy individuals form overly pessimistic beliefs and avoid being cheated, but give up...

The influence of cultural identity on willingness to pay values in contingent valuation surveys
Provedor de dados: 31
Autores: Awatere,   Shaun.
Current New Zealand resource management legislation requires local government actively recognise and take into account Māori values in resource management planning. This means the decision process and participants must interact with evidence based on Māori epistemologies. The Māori world-view is holistic in nature in that it embodies historical, environmental, and spiritual values, as well as modern experiences. Concerns arise for Māori communities when planners and developers utilise economic tools such as willingness to pay surveys to determine the total value of a proposed project. Other concerns are caused by surveys that ask a participant “are you Māori” and fail to recognise the diverse realities that exist for Māori. This paper draws from a survey...

The Racial Saving Gap Enigma: Unraveling the  Role of Institutions
Provedor de dados: 31
Autores: Belton,   Willie; Uwaifo Oyelere,   Ruth.
It has been well documented in the literature that ethnicity matters significantly in the determination of savings. In particular, African-American savings lag far behind that of other ethnic groups. Similarly, the literature also provides evidence of the long-lived nature of institutions and the link between institutions and culture. In this paper, we provide an explanation for the savings gap that still exists between African-Americans and White Americans even after accounting for appropriate factors that can lead to savings differentials. We initially provide evidence that the savings gap exists and persist after including several control variables in a  regression analysis. We then provide evidence that the persistent gap can not be attributed solely...

Autores: Runge,   C. Ford; Bagnara,   Gian Luca; Jackson,   Lee Ann.
This paper provides an overview of the historical and cultural factors that have contributed to divergent U.S. and European views on GMOs, and to resulting different national regulatory approaches for these products, specifically labelling policy. Within the context of the international trading system, these national policy choices will have impacts that will spill over national borders. Dialogue may be difficult to achieve, given widely divergent views concerning GMOs; however, without dialogue potential global social benefits of policy harmonization will be forfeited.

Culture and values - their relevance for marketing strategies
Provedor de dados: 31
Autores: Rewerts,   Astrid Lucie; Hanf,   Jon Henrich.
Research on consumer behaviour has revealed that the prospect of reaching a personal value is the virtual buying motive. Bearing this in mind, the researcher, as well as the marketer, is not only able to observe whether one product is preferred to another, but also to understand why this product is preferred. Hence, identifying consumers' personal values contributes to explaining consumer preferences and buying motives, which is of great importance for marketing practice. Personal values that are developed during the process of socialisation are part of a culture and differ depending on one's cultural background. Therefore, culture- specific values result in specific consumer behaviour. The aim of our paper is to combine research about buying motives...

Adversities, generally, have the capacity to generate behaviors that aggregate people. The objective of this work is to propose an analytical structure, using approaches such as social entrepreneurship, culture, knowledge and cooperation, to treat systematically the competitiveness dilemma that agricultural cooperatives face. The premise of this structure is that the social entrepreneurship that supports organizations such as agricultural cooperatives brings together culture, knowledge and a cooperative stance, which tend to influence the performance of the organization through their presence in its other internal factors. The basic concept of a cooperative organization is its most important differentiating factor because it presupposes that the purpose of...

Experiments were carried out in order to test the efficiency of additions of secondary sewage as a culture medium for Chaetoceros gracilis and Thalassiosira sp (Chrysophyceae) under laboratory conditions. These algae were cultivated in sea water with concentrations of 10%, 20%, 30% and 40% of wastewater. The results were compared with those obtained by the nutritive medium f2 of Guillard (1975). The best results in terms of cellular densities were observed at 40% additions. There were significant differences (significance levels of 5%) between the nutritive medium f2 and the 40% additions for both the species. Maximum cellular densities observed for all additions tested were, 4,125.00 x 10³ cells/ml for Chaetoceros gracilis on the ninth day and 834.00 x...

Lupus vulgaris is the most common form of cutaneous tuberculosis which usually occurs in patients previously sensitized to Mycobacterium tuberculosis. We present a case of a 10-year-old boy who was diagnosed as lupus vulgaris clinically and histopathologically. He had well demarcated, irregularly bordered, pink, infiltrated plaques on his left cheek showing apple-jelly appearance on diascopy. The histopathological examination showed tuberculoid granulomas with Langhans type giant cells. The Mantoux reactivity was in normal limits, and no acid-fast bacilli was found in the lesion, either by direct stained smears or by culture. The lesions showed marked improvement on anti-tuberculosis treatment. We want to emphasize that histopathological examination has...

Streptococcus agalactiae or group B Streptococcus (GBS) is one of the most important causal agents of serious neonatal infections. Numerous assays have been evaluated for GBS screening in order to validate a fast and efficient method. The aim of this study was to compare the culture technique (established as the gold standard) with the molecular method of polymerase chain reaction (PCR) with specific primers (atr gene).

The objective of this study was to determine the effects of GDF-9, IGF-I, and GH alone or combined on preantral follicle survival, activation and development after 1 and 7 days of in vitro culture. Either fresh (non-cultured) or cultured ovarian tissue was processed for histological and fluorescence analysis. For all media tested, the percent of normal follicles was greater when compared to minimum essential medium supplemented (MEM+) alone, except when ovarian tissue was cultured with GDF-9/IGF-I or GDF-9/GH (P &lt; 0.05). Fluorescence analysis showed that the percent of viable follicles after 7 days of culture was similar for non-cultured tissue and for all treatments tested. The percent of primordial follicles was reduced (P &lt; 0.05) and there was a...

Isolation of leptospira Serovars Canicola and Copenhageni from cattle urine in the state of Paraná, Brazil
Provedor de dados: 58
Autores: Zacarias,Francielle Gibson da Silva; Vasconcellos,Silvio Arruda; Anzai,Eleine Kuroki; Giraldi,Nilson; Freitas,Julio Cesar de; Hartskeerl,Rudy.
In 2001, 698 urine samples were randomly collected from cattle at a slaughterhouse in the State of Paraná, Brazil. Direct examination using dark field microscopy was carried out immediately after collection. Five putative positive samples were cultured in modified EMJH medium, yielding two positive cultures (LO-14 and LO-10). Typing with monoclonal antibodies revealed that the two isolates were similar to Canicola (LO-14) and Copenhageni (LO-10). Microscopic agglutination test results show that Hardjo is the most common serovar in cattle in Brazil. Rats and dogs are the common maintenance hosts of serovars Copenhageni and Canicola. The excretion of highly pathogenic serovars such as Copenhageni and Canicola by cattle can represent an increasing risk for...

Helicobacter pylori infects nearly 50% of the world's population. This microorganism is accepted as the most important agent of gastritis and as a risk factor for peptic ulcer disease and gastric adenocarcinoma. Currently many diagnostic methods exist for detecting H. pylori, however they all have limitations, thus it is recommend a combination of at least two methods. The aim of this study was to evaluate diagnostic methods, such as in-house urease test, culture and Polymerase Chain Reaction (PCR), for the detection of the H. pylori in gastric biopsy specimens of 144 dyspeptic patients, using as gold standard the association between histology and rapid urease test. According to the gold standard used in this study, 48 (33.3%) patients were infected with...

Autores: Monteiro,Paulo Henrique Tasso; Martins,Maria Conceição; Ueki,Suely Yoko Mizuka; Giampaglia,Carmen Maria Saraiva; Telles,Maria Alice da Silva.
The identification of Mycobacterium tuberculosis complex (MT), using non-molecular methods, is time-consuming. The objective of this study was to evaluate a screening test for the presumptive identification of MT, which could potentially decrease laboratory turn-around time for reporting preliminary results. From January 1998 to December 1999, 3056 cultures were analysed at the Mycobacterial Laboratory, Instituto Adolfo Lutz, São Paulo, Brasil. The screening test consisted of observation of colony morphology on Löwenstein Jensen medium and evaluation of cord formation on smear microscopy from those positive cultures. After the screening test, the cultures identified as non-tuberculous mycobacteria were identified to species by conventional methods (growth...
