Public support for protected areas depends, in part, upon clear demonstrations of the importance of the ecosystem services provided by these areas. However, only a limited number of studies have examined the value of protected areas in providing these services, and even less work has assessed how equitably these benefits are distributed across society. We used on-site surveys to characterize people who derived recreational benefit from a set of areas in the United Kingdom that were originally protected for their conservation value. We found that an unrepresentative subset of society enjoyed this benefit. Site visitor populations were biased towards older people and men, and minority groups were starkly underrepresented, comprising only 1% of overall...

Understanding cultural dimensions of human/environment relationships is now widely seen as key to effective management, yet characterizing these dimensions remains a challenge. We report on an approach for considering the nonmaterial values associated with ecosystems, i.e., cultural ecosystem services. We applied the approach in Kona, Hawai&amp;#8216;i, using 30 semistructured interviews and 205 in-person surveys, striving to balance pragmatism and depth. We found spirituality, heritage, and identity-related values to be particularly salient, with expression of some of these values varying among respondents by ethnicity and duration of residence in Hawai&amp;#8216;i. Although people of various backgrounds reported strong spirituality and heritage-related...

SRo112: an improved mapmaking approach to reduce large-scale systematic effects in the Planck High Frequency Instrument legacy maps
Provedor de dados: 5
Autores: Delouis, Jean Marc; Pagano, L.; Mottet, S.; Puget, J-l; Vibert, L.
This paper describes an improved map making approach with respect to the one used for the Planck High Frequency Instrument 2018 Legacy release. The algorithm SRo112 better corrects the known instrumental effects that still affected mostly the polarized large-angular-scale data by distorting the signal, and/or leaving residuals observable in null tests. The main systematic effect is the nonlinear response of the onboard analog-to-digital convertors that was cleaned in the Planck HFI Legacy release as an empirical time-varying linear detector chain response which is the first-order effect. The SRo112 method fits the model parameters for higher-order effects and corrects the full distortion of the signal. The model parameters are fitted using the redundancies...

La pêche aux petits metiers en Languedoc-Roussillon en 2000 - 2001
Provedor de dados: 5
Autores: Guillou, Alain; Lespagnol, Patrick; Ruchon, François.
"Small trades" refers to the body of fishing boats, excepting the trawlers, which have a trawling license and the tuna/sardine boats, which have a pelagic fishing license. The ships that fish for small pelagic fish by using a lamp are only included for the other trades they ply, if applicable. Whereas certain "small trades" work offshore, the majority of them exploit the lagoons and coastal area. The importance of the coastal areas in general, where a large number of biological and ecological processes are being developed, need no longer be demonstrated: A large part of primary and secondary production takes place in these areas, which host moreover many reproduction and nursery sites for a great many species. "Small trade" fishing is one of the main...

Shedding light on the river and sea lamprey in western European marine waters
Provedor de dados: 5
Autores: Elliott, Sam; Deleys, Noemie; Rivot, E; Acou, A; Réveillac, E; Beaulaton, L.
Lampreys are ancestral jawless vertebrates with particularly complex life histories. Population declines resulting from increased anthropogenic pressure have been observed. For semelparous diadromous lampreys, the marine phase remains largely a black box, making targeted management and conservation measures difficult to implement. Here, we collated a database of 168904 hauls from both fisheries-dependent and fisheries-independent surveys between 1965 and 2019. Lampreys were observed in only 254 hauls (&lt;1% lamprey presence); 421 sea lamprey Petromyzon marinus and 300 European river lamprey Lampetra fluviatilis were identified. Sizes ranged from 13 to 92 cm and from 14 to 42 cm, respectively. The majority of lampreys (61%) were caught by mobile demersal...

Observatoires sismiques sur le fond de la mer
Provedor de dados: 5
Autores: Avedik, Felix.
Detecting and localizing nuclear blasts was an essential stimulus of the actions undertaken in the 1960's to emplace seismological observatories on the seafloor. The plate-tectonic theory, in which the oceanic areas play a major role, greatly accelerated the evolution of modern oceanology. The contribution of Ifremer's department of Marine Geosciences, in helping to advance this area of research, has been significant since 1972. The need for refraction studies to explore the deep structure of the margins and ocean-continent transition zones led us to design a deep-sea Ocean Bottom Seismograph (OBS) MK I in 1975, rated to 6,000 metres depth. This system introduced, for the first time, the concept of "isolated seismic sensors". This principle was adopted...

IFREMER instrumentation, strategy and calculations used during echo sur veys are  described in details and criticized. Five acouslic sur veys carried o t in the Bay of Biscay between 1983 and 1987 show that several species are generally mixed , and lheir identification is very oflen biased by behaviour phenomena. A new way of classi fying echotraces and interpretating data has been applied to these surveys. The results are summarized in tables and maps. Whenever multispecies structures are concerned, it seems at present impossible to assess absolute biomasses based on acoustic survey method. ln such a situation, acoustic surveys...

Results of the IODE Priority Survey (polled 17 September – 11 October 2004)
Provedor de dados: 20
In view of the ongoing review of IODE, the planned development of an IOC data management strategy and the preparations of the JCOMM strategy it is important that the IODE data and information management community thinks about the prioritization of IODE activities and projects. There are currently a significant number of global and regional projects. Some of these are funded through donors but many require IOC funding. As the funding for IODE for the UNESCO regular programme is not likely to increase it is necessary to reflect on which projects IODE can afford to continue and which ones may need to end. Through the survey all IODE data managers and information managers were given an opportunity to express their opinion.

Evaluation of the Status of the Namibian Hake Resource (Merluccius spp.) Using Statistical Catch-at-Age Analysis
Provedor de dados: 20
Autores: Kirchner, Carola; Kainge, Paul; Kathena, Johannes.
Namibian hake is the most important fish resource in Namibia. This monograph is a compilation of all the hake data, historic and recent, that has been used to inform stock assessment and management since the late 1970s. It presents the statistical catch-at-age analysis used to evaluate the state of the Namibian hake resource under different assumptions. This analysis treats the two hakes, Merluccius paradoxus and M. capensis, as a single stock. The data and modeling show that the stock has not as yet recovered to its maximum sustainable yield level, despite foreign fishing effort having been removed in 1990. Best estimates suggest the current stock to be roughly 20% of pre-exploitation levels; however this figure is sensitive to model assumptions. Signs...

The data belong to the demersal fishery research cruise H-13/94. Stratification used for research surveys from the catches values was tested, both for the northern area, Argentine-Uruguayan Common Fishing Zone (AUCFZ) located between 34° and 39°S, and the southern area situated between 38°30' and 41°30'S (El Rincón, Buenos Aires Prov., Argentina). The variables considered were: croaker and striped weak fish densities and depth. Discriminant factor analysis indicates the formation of two and six strata for the southern and northern areas respectively. The adequate confidential limits of the estimated biomass for each strata obtained for different species, indicate that the criteria for stratification is satisfactory. The number of catches by strata was...

Oceanographic and faunistic structures across an Angola Current intrusion into northern Namibia waters.
Provedor de dados: 20
Autores: John, H.C.H.; Mohrholz, V.; Lutjeharms, J.R.E.
It is thought that the penetration of Angolan waters through the Angola–Benguela Frontal Zone (ABFZ) into the much cooler Benguela regime may come about by a poleward slope undercurrent as well as by cross-frontal filaments. To test this hypothesis, two zonal transects off the northern Namibian coast were surveyed by CTD casts, current measurements and ichthyoplankton samples during April 1999. Simultaneous sea-surface temperature (SST), chlorophyll-a concentration, and wind data were obtained from satellite. The multidisciplinary results are described.An intense intrusion of the Angola Current into northern Namibian waters occurred with distinct signals of high temperatures and salinities, low chlorophyll-a concentration, and Angolan fish larvae of both...

In Spring 2005 and Fall 2009 consumer surveys were collected in several Metropolitan 4 cities in Indiana and Illinois to explore differences based on psychographic and behavioral 5 characteristics of farmers’ market consumers. Consumer intercept surveys were conducted in: 6 South Bend, IN; Bloomington, IN; Springfield, IL and Peoria, IL. Likert scale questions were 7 analyzed using factor and hierarchical cluster analysis to identify clusters of consumers based on 8 several farmers’ market characteristics. Survey results show that of the 164 Metropolitan 9 surveys analyzed, 85.3% of respondents were Caucasian, 71.9% were between the ages of 35 and 10 64 and 78% were female. Data analysis showed that four clusters were formed: Recreational 11 (42%),...

In-Store Evaluation of Consumer Willingness to Pay for “Farm-Raised” Pre-Cooked Roast Beef: A Case Study
Provedor de dados: 31
Autores: Nalley,   Lawton Lanier; Hudson,   Darren; Rogers,   Robert W.; Martin,   James M.; Herring,   Joshua L.
A choice-based conjoint experiment was used to examine consumer willingness to pay for a farm-raised pre-cooked roast beef product. Consumers were contacted in a grocery store and provided a sample of the pre-cooked product. Findings indicate there is a small, but statistically significant willingness-to-pay premium for the farm-raised product, suggesting that some product differentiation may result in higher prices for these products. The study outlines an approach to marketing research.

Through a survey of scientists from the International Maize and Wheat Improvement Center (CIMMYT) in 2004, this study assessed the extent to which participatory methods had been used by the center, how they were perceived by the scientists, and how participatory research could be applied more effectively by CIMMYT and partners. Results for 19 CIMMYT projects suggest among other things that participatory approaches at the center were largely “functional”—that is, aimed at improving the efficiency and relevance of research—and had in fact added value to the research efforts. The authors suggest that CIMMYT should (1) create a more conducive environment for scientists to share experiences on such approaches and (2) better document their impacts on farmers’...

The Importance Of Indigenous Biodiversity On Waikato Farms
Provedor de dados: 31
Autores: Trinh,   Phuong Khanh; Kaval,   Pamela.
In this paper, we studied the importance of indigenous biodiversity (native bush) on farm properties in the Waikato Region. To do this, we surveyed both real estate agents and farmers. We discovered that opinions of native bush between the two groups were very different. A small percentage of real estate agents believed that indigenous biodiversity on farms mattered; type of farm sold and age of respondent influenced this belief. While approximately half of Waikato farmers believed that native bush was important; this was influenced by age, income, education level, number of farm owners and sex. Farmers suggested that rates rebates, as well as subsidized planting and subsidized fencing would motivate them to plant more native bush on their lands.

Status and management of the sea cucumber fishery of La Grande Terre, New Caledonia.
Provedor de dados: 31
Autores: Purcell,   Steven W.; Gossuin,   Hugues; Agudo,   Natacha N.
From October 2006 to May 2008, The WorldFish Center coordinated a ZoNéCo project to provide support to the Southern and Northern Provinces for decisions about how best to manage the sea cucumber fishery around La Grande Terre. We collected data during underwater population surveys, questionnaire-based interviews with fishers and processors, and landing catch surveys. A core aim was to furnish the Provinces with ‘ballpark’ estimates of the abundance and density of commercially important sea cucumbers on 50 lagoon and barrier reefs. Analysis and synthesis of the ecological and sociological data provide the basis for informed recommendations for fisheries management. Counts of trochus and giant clams on the reefs allow us to also describe the general status...

Invasion of North American beaver (Castor canadensis) in the province of Magallanes, southern Chile: comparison between dating sites through interviews with the local community and dendrochronology
Provedor de dados: 97
Autores: Graells,Giorgia; Corcoran,Derek; Aravena,Juan Carlos.
BACKGROUND: Twenty beavers Castor canadensis (Castoridae) were initially introduced in the Argentinean portion of Tierra del Fuego Island, from where they have occupied most of the Fuegian Archipelago and even reached the continent. This invasion is causing great damage to the subantarctic forest ecosystems, and it is not known how fast the species is spreading. While there is an estimation of this advance using interviews, it is not known how reliable these are and they cannot be made in remote areas. On the mainland, where beavers were present, their date of arrival was estimated using interviews and dendrochronology, and the dates obtained by both methods were compared for each site. RESULTS: Differences were found among the groups of respondents,...

Provedor de dados: 49
Autores: Boff,Samuel; Araujo,Andréa Cardoso; Pott,Arnildo.
This is the first systematic survey of bees in the Pantanal wetland, Brazil. We recorded bee species and their floral resources within grassland and natural forest edge habitats in the Pantanal. Surveys were conducted during two to four-days per month, for a total of 12 months. Overall, we recorded 56 bee species visiting a total of 63 flowering plants. Asteraceae and Fabaceae presented the highest number of visited species, however Hyptis suaveolens (Lamiaceae) was the plant most visited by different bee species (18). The most generalist native bee was Trigona fuscipennis visiting a total of 17 flowering plant species. Apis mellifera, an exotic bee, visited 27 species. We also report the overlap (37.5%) in the use of floral resources between the exotic...

Provedor de dados: 56
Autores: Galduróz,J.C.F.; Noto,A.R.; Nappo,S.A.; Carlini,E.A.
The consumption of psychotropic drugs among Brazilian secondary school students was examined by comparing data from four surveys using a questionnaire adapted from the WHO's Program on Research and Reporting on the Epidemiology of Drug Dependence. Students filled out the form in their classrooms without the presence of teachers. The target population consisted of 10-18-year-old students (on average, 15,000 students responded to each survey) in Brazil's ten largest state capitals: Belém, Belo Horizonte, Brasília, Curitiba, Fortaleza, Porto Alegre, Recife, Rio de Janeiro, Salvador, and São Paulo. Among the legal drugs, lifetime use (use at least once during life) of tobacco was increased in seven cities (the exceptions were Brasília, Porto Alegre and Rio de...
