The hunting and trade of bushmeat is a significant issue. The sharing of marine bushmeat between Australian Torres Strait Islanders and their mainland urban diaspora was documented from a diaspora perspective by collecting quantitative and qualitative data from communities in three mainland cities. Motivations for sharing dugong and turtle meat were almost exclusively cultural and mostly occurred when a diaspora member visited Torres Strait, when Torres Strait Islanders visited their mainland family, during Islander ceremonies, or when goods were exchanged as gifts. Each respondent consumed relatively little dugong and turtle meat (<1–2% of annual meat consumption, or < 1 kg per person per annum). Sharing bushmeat strengthened social capital and reinforced cultural identity. Harnessing the social capital generated from the sharing of bushmeat to engage the urban diaspora in dugong and turtle management activities in the Torres Strait could enhance the legitimacy and effectiveness of such initiatives. 相似文献

In this study, 10% of all registered fishermen in the coastal towns of Navachiste in Sinaloa, in northwestern Mexico, answered a survey designed to collect data on their perceptions of the following topics: the impact of turtle meat consumption; human health; bycatch; illegal turtle fishing; the illegal sea turtle market; the local economy; pollution; environmental education; the success of protective legislation; and sea turtle‐based ecotourism. Perceptions were analyzed using the fuzzy logic method through classification into 5 fuzzy membership sets: VL, very low; L, low; M, moderate; H, high; VH, very high. The 9 topics generated decision areas upon applying fuzzy inference that revealed the membership level of the answers in each fuzzy set. The economic potential of sea turtle‐based ecotourism and the economic profitability of the illegal turtle meat market were perceived as VL. Conservation legislation was perceived as H, although inefficiently applied due to corruption. Ecotourism and impacts on sea turtles were perceived as VL, because they were deemed unprofitable activities at the individual and community levels. Environmental education was perceived as L, because it centers on nesting, hatching and releasing turtles and is directed at elementary and middle‐school students. While fishers perceive a serious negative impact of fishing activities on sea turtles in the San Ignacio‐Navachiste‐Macapule area, they do not see themselves individually as part of the problem. Achieving sea turtle conservation in this region requires: suitable ecotourism infrastructure, government investments in promotion, and studies to estimate the minimum number of tourists needed to assure profitability. 相似文献

Considerable research has been conducted analyzing how demographic characteristics influence the public’s attitudes toward wildlife; however, less research of this type has been conducted in locations having long-standing species conservation efforts. Questionnaires were completed by residents living adjacent to such a location, the Archie Carr National Wildlife Refuge (ACNWR), to investigate which demographics explained residents’ knowledge of, attitudes toward, willingness to act for, and participation in sea turtle conservation. Residents who had a non-governmental organization (NGO) or government agency as their sea turtle information source had stronger positive attitudes toward sea turtles. Residents who possessed strong positive attitudes were more willing to engage in pro–sea turtle conservation behaviors. Overall, this research demonstrated that ACNWR residents’ source of sea turtle information being an NGO or government agency played a significant role in increasing residents’ knowledge of, attitudes toward, willingness to volunteer for, and participation in sea turtle conservation. 相似文献

This paper analyzes rancher participation in conservation programs in the context of a social-ecological framework for adaptive rangeland decision-making. We argue that conservation programs are best understood as one of many strategies of adaptively managing rangelands in ways that sustain livelihoods and ecosystem services. The framework hypothesizes four categories of variables affecting conservation program participation: operation/operator characteristics, time horizon, social network connections, and social values. Based on a mail survey of California ranchers, multinomial logit models are used to estimate the impact of these variables on different levels of rancher involvement in conservation programs. The findings suggest that ranchers with larger amounts of land, an orientation towards the future, and who are opinion leaders with access to conservation information, are more likely to participate in conservation programs. 相似文献

Evidence suggests that religion is an important driver of peoples’ attitudes toward nature, but the link between religion and carnivore conservation is poorly understood. We examined peoples’ attitudes in Buddhist (n = 83) and Muslim communities (n = 111) toward snow leopards (Panthera uncia) and wolves (Canis lupus) in Ladakh, India. We found that the effect of religion on attitudes was statistically nonsignificant, and was tempered by gender, education, and awareness of wildlife laws. Even though religion by itself was not an indication of an individual’s attitude toward large carnivores, the extent to which he/she practiced it (i.e., religiosity) had a positive correlation with pro-carnivore attitudes in the case of Buddhist but not Muslim communities. Our findings indicate that it may be useful to integrate locally relevant religious philosophies into conservation practice. However, the emphasis of conservation messaging should vary, stressing environmental stewardship in the case of Islam, and human–wildlife interdependence in the case of Buddhism. 相似文献

AIM: To describe the microscopic and immunohistochemical findings in a case of pulmonary hyalohyphomycosis in a Kemp's ridley sea turtle (Lepidochelys kempi). METHODS: Samples of lung, liver and kidney from a stranded, dead Kemp's ridley sea turtle were routinely processed for histopathological studies. Two monoclonal antibodies that reacted specifically with antigens of Aspergillus spp and the Mucorales (Zygomycetes) group, and a panel of polyclonal antibodies raised against Aspergillus fumigatus, Candida albicans, Geotrichum candidum, Fusarium solani, and Scedosporium apiospermum were used for immunohistochemical or immunofluorescence staining. RESULTS: Histologically, a severe multifocal granulomatous pneumonia associated with fungal infection was diagnosed. All hyphae were identified as Fusarium spp because a strong and uniform reactivity was obtained only with a heterologously-absorbed polyclonal antibody raised against somatic antigens of Fusarium solani. CONCLUSIONS: Fusarium spp should be included in the differential diagnosis of mycotic pneumonia in Kemp's ridley sea turtles. CLINICAL RELEVANCE: This is the first report of a pulmonary mycotic infection in a sea turtle diagnosed using immunohistochemistry. Wildlife rehabilitators and pathologists should be aware of the availability of immunohistochemical techniques for identifying fungi in sea turtles. 相似文献

Wild dogs contribute to a range of negative impacts in Australian peri-urban regions. We identified and prioritized 13 behaviors that peri-urban residents could engage in to reduce the impacts of wild dogs in their communities. Key-informant interviews and stakeholder focus groups were used to develop a list of wild dog-management behaviors. On-line surveys with wild dog experts (n = 10) and peri-urban residents (n = 302) were used to create a Behavior Prioritization Matrix (BPM), which ranked the behaviors in terms of projected impact, based on: (a) expert estimates of effectiveness, (b) current adoption levels (penetration), and (c) likelihood of future adoption. BPM analysis indicated that increasing community reporting of wild dogs and their impacts would produce the greatest overall benefits for wild dog management. Behaviors rated as highly effective by experts (e.g., baiting and trapping) had low projected impact given that they were unlikely to be adopted by most residents. 相似文献

Background: Plasma biochemical and hematologic variables are important in the management of endangered sea turtles, such as loggerheads. However, studies on blood biochemistry and hematology of loggerheads are limited, and different concentrations according to variable criteria have been reported. Objective: The purpose of this study was to establish and compare baseline plasma chemistry and hematology values in Eastern Atlantic juvenile and adult nesting loggerhead sea turtles (Caretta caretta). Methods: Blood samples were collected from 69 healthy juvenile loggerhead sea turtles after their rehabilitation in captivity, and from 34 adult nesting loggerheads after oviposition. Fresh blood was used for leukocyte differential count and PCV determination. Heparinized blood was used for RBC and WBC counts. Plasma biochemical concentrations were measured using an automated biochemical analyzer. For the comparative study, nonparametric statistical analysis was done using the Mann–Whitney U‐test. Results: Minimum, maximum, and median concentrations were obtained for 14 hematologic and 15 plasma chemistry variables. Statistically significant differences between juvenile and adult turtles were found for PCV; RBC, WBC, and leukocyte differential counts; total protein, albumin, globulins, calcium, triglycerides, glucose, total cholesterol and urea concentrations; and lactate dehydrogenase activity. Conclusions: Age, size, and reproductive status cause important variations in the hematologic and plasma biochemical results of loggerheads. The reference values obtained in this study may be used as a standard profile, useful for veterinary surgeons involved in sea turtle conservation. 相似文献

Salmonellae are Gram‐negative zoonotic bacteria that are frequently part of the normal reptilian gastrointestinal flora. The main objective of this project was to estimate the prevalence of non‐typhoidal Salmonella enterica in the nesting and foraging populations of sea turtles on St. Kitts and in sand from known nesting beaches. Results suggest a higher prevalence of Salmonella in nesting leatherback sea turtles compared with foraging green and hawksbill sea turtles. Salmonella was cultured from 2/9 and identified by molecular diagnostic methods in 3/9 leatherback sea turtle samples. Salmonella DNA was detected in one hawksbill turtle, but viable isolates were not recovered from any hawksbill sea turtles. No Salmonella was detected in green sea turtles. In samples collected from nesting beaches, Salmonella was only recovered from a single dry sand sample. All recovered isolates were positive for the wzx gene, consistent with the O:7 serogroup. Further serotyping characterized serovars Montevideo and Newport present in cloacal and sand samples. Repetitive‐element palindromic PCR (rep‐PCR) fingerprint analysis and pulsed‐field gel electrophoresis of the 2014 isolates from turtles and sand as well as archived Salmonella isolates recovered from leatherback sea turtles in 2012 and 2013, identified two distinct genotypes and four different pulsotypes, respectively. The genotyping and serotyping were directly correlated. To determine the persistence of representative strains of each serotype/genotype in these environments, laboratory‐controlled microcosm studies were performed in water and sand (dry and wet) incubated at 25 or 35°C. Isolates persisted for at least 32 days in most microcosms, although there were significant decreases in culturable bacteria in several microcosms, with the greatest reduction in dry sand incubated at 35°C. This information provides a better understanding of the epizootiology of Salmonella in free‐ranging marine reptiles and the potential public health risks associated with human interactions with these animals in the Caribbean. 相似文献

Growing populations of American alligators (Alligator mississippiensis) in human-dominated landscapes present a challenge to wildlife managers concerned with promoting coexistence between humans and alligators. Where structural fixes such as direct removal of animals are not viable options, cognitive fixes such as conservation education programs should be considered. We evaluated the effectiveness of two conservation education programs (classroom-based program, field excursion) on three outcome variables that help define wildlife acceptance capacity for American alligators: beliefs and attitudes, perceived risk, and potential for coexistence. We found respondents who took part in both education programs had more positive beliefs and attitudes toward alligators, and believed in a greater potential for coexistence than individuals in a control group who did not undergo either intervention. Control group respondents also perceived higher risk from alligators. These data suggest that conservation education programs can impact stakeholder beliefs, attitudes, and perceptions, ultimately influencing acceptance capacity for predators. 相似文献

Volunteers can contribute to wildlife conservation by protecting and restoring habitat, or by collecting citizen science data. Much remains unknown about how citizen scientists contribute to conservation beyond data collection, or the extent that volunteering with citizen science or habitat conservation is associated with increased participation in other forms of conservation. We surveyed citizen science and habitat volunteers from monarch butterfly (Danaus plexippus) programs. Both types of volunteers conducted conservation outreach and created and managed monarch habitat. Habitat volunteers were more likely to create new habitat for monarchs in urban or suburban areas, whereas citizen scientists were more likely to maintain existing habitat in rural areas. Most volunteers increased their participation in conservation after joining a formal monarch project. Our results provide information about the capacity for habitat volunteers to engage in conservation, as well as evidence of an unexplored benefit of citizen science, the creation and protection of habitat. 相似文献

Objective The Leatherback sea turtle is the largest extant reptile and the sole member of the family Dermochelyidae. Here, the eye of this critically endangered marine turtle was investigated to determine the anatomy, optics, and optical sensitivity. Animals studied Three Leatherback sea turtles, Dermochelys coriacea. Results The eye is small in proportion to body size of the adult compared to other vertebrates, with prominence of the retractor bulbi and pyramidalis muscles. The nictitans shows extensive folding of the bulbar conjunctiva as an apparent mechanism to increase the surface area for mucus secretion. The intraocular anatomy is consistent with an eye adapted to aquatic vision with minimal curvature of the cornea, a near‐spherical lens, deep ciliary cleft and highly vascularized ciliary body. The optical sensitivity, a measure of the sensitivity to light of a given optical system, is higher than in other marine turtles studied but lower than those found in teleost fish that share a habitat with the Leatherback sea turtle. Conclusions The Leatherback sea turtle shows ocular features that are characteristic of Chelonians with similarities to aquatic mammals. The calculated optical sensitivity suggests that compared to pelagic fishes, for instance, the Leatherback sea turtle eye is not particularly well adapted for vision in dim light even though this species is known to venture into deep, dark waters, and might feed at night. 相似文献

Bird watchers (birders) are stakeholders in wildlife conservation; yet, few federal programs provide formal mechanisms for birders to contribute economically to conservation. One exception is the Migratory Bird Hunting and Conservation Stamp (duck stamp), a unique conservation tool historically aimed at waterfowl hunters that generates revenue to acquire and protect wetland habitat. This article examined duck stamp purchasing behavior among birders participating in the National Audubon Society’s annual citizen science project, the Christmas Bird Count (CBC) (n = 3,072). Twenty percent of CBC participants had purchased a duck stamp between 2013 and 2015, and about 40% of those purchasers were also hunters. Birding specialization was a key predictor of duck stamp purchasing behavior, with highly specialized nonhunting birders purchasing stamps at rates approximately equal to hunters. Future research should continue to explore reasons birders buy (or do not buy) duck stamps and the broader implications on wildlife conservation. 相似文献

A morphologic classification based on the cytochemical characteristics of blood cells of 35 juvenile loggerhead sea turtles (Caretta caretta) is described. Cytochemical stains included benzidine peroxidase, chloroacetate esterase, alpha-naphthyl butyrate esterase (with and without sodium fluoride), acid phosphatase (with and without tartaric acid), Sudan black B, periodic acid-Schiff, and toluidine blue. The morphologic characteristics of erythrocytes were similar to those reported in green turtles. Six types of white blood cells were identified: heterophils, eosinophils, basophils, lymphocytes, monocytes and thrombocytes. Except for the basophils, the rest of the white blood cells from loggerhead turtles had different cytochemical characteristics compared to blood cells from other sea turtle species. The leukocyte differential count was different from that reported for other sea turtle species. Heterophils were the most numerous leukocytes from these loggerhead turtles, followed by lymphocytes, eosinophils, monocytes and basophils. This paper provides a morphologic classification of blood cells of loggerhead sea turtles that is useful for veterinary surgeons involved in sea turtle conservation. 相似文献

Stated preferences of llama keeping functions in Bolivia 总被引：1，自引：0，他引：1

Bolivia accounts for approximately 63% of the South American llama population. Llamas keep playing an important role in the subsistence of smallholdings in the Andean regions fulfilling various functions in the productive, social and cultural life of the people. The present study evaluates functions of llama keeping as a prerequisite to the formulation of a community-driven breeding programme. A ranking approach was applied with 75 farmers in 6 villages. Sampling considered the factors gender and central versus remote communities. The different functions were presented visually. Each farmer was asked to arrange the illustrations according to his preference order. In total, 10 functions were suggested, covering the categories transport, sale or use of products, integration of animals in cultural events and herd size as capital asset. Ranking frequencies of stated preferences were calculated. A rank-based t-test was applied for multiple pair-wise comparisons within ranking groups gender and community provenance, respectively. Between-group comparison was performed by non-parametric Wilcoxon rank-sum test. The capital function was most important (14.6% of total ranking frequency) followed by the transport function to cultivated areas (13.7%) and the transport function for other purposes in third place (10.8%). All pair-wise comparison analysis indicated a significant difference for the two highest ranked functions. Functions ranked from 3rd to 9th position showed poor separation due to similar means with high variance. Bottom ranked function with significant separation for all ranking groups was the ‘Integration of animals in cultural events or rituals’. Women appreciated the dung of the animals more than men (p = 0.0376), whereas men put higher value on the sale of live animals for cash generation in case of emergency (p = 0.0006) and for cash availability (p = 0.0371). It is concluded that traditionally important functions of llamas like wealth accumulation and the close integration of the animals in mixed farming systems prevail. Breeding policies and breeding decisions will be more suitable when taking into account farmers' preferences and gender-specific perceptions. 相似文献

Jaguars and pumas are threatened species in Brazil’s Atlantic Forest, especially at the borders of protected areas. This article assessed the influence of emotions, attitudes, existence value, and agency credibility on acceptability of big cats among rural residents living adjacent to two protected areas in this forest. Data from self-administrated questionnaires (n = 326) indicated those with positive attitudes toward big cats (β = .28, p < .001), those who valued the existence of big cats (β = .14, p < .05), those who would feel sorrow if big cats disappeared (β = .21, p < .001), and those who considered the managing agency as credible (β = .16, p = .002) were more accepting of big cats. The model provided theoretical and practical insights into large carnivore conservation. For example, given the significance of agency credibility, a positive relationship between park authorities and residents is crucial for big cat conservation. 相似文献

OBJECTIVE: To compare blood biochemical values obtained from a handheld analyzer, 2 tabletop analyzers, and 2 diagnostic laboratories by use of replicate samples of sea turtle blood. DESIGN: Validation study. ANIMALS: 22 captive juvenile sea turtles. PROCEDURES: Sea turtles (18 loggerhead turtles [Caretta caretta], 3 green turtles [Chelonia mydas], and 1 Kemp's ridley turtle [Lepidochelys kempii]) were manually restrained, and a single blood sample was obtained from each turtle and divided for analysis by use of the 5 analyzers. Hematocrit and concentrations or activities of aspartate aminotransferase, creatine kinase, glucose, total protein, albumin, BUN, uric acid, P, Ca, K, Na, Cl, lactate dehydrogenase, and alkaline phosphatase were determined. Median values for each analyte were compared among the analyzers. RESULTS: Significant differences were found among the analyzers for most values; however, data obtained from the 2 diagnostic laboratories were similar for all analytes. The magnitude of difference between the diagnostic laboratories and in-house units was > or = 10% for 10 of the 15 analytes. CONCLUSIONS AND CLINICAL RELEVANCE: Variance in the results could be attributed in part to differences in analyzer methodology. It is important to identify the specific methodology used when reporting and interpreting biochemical data. Depending on the variable and specific case, this magnitude of difference could conceivably influence patient management. 相似文献
