This article aims to evaluate the influence of the desiccation of the Ciénaga de Aguablanca on regional climate. The periodization of the desiccation and urban growth of Cali was reconstructed under the theoretical contributions of environmental history. As complementary sources, maps, aerial photographs, and diagrams of the city were obtained from 1944 to 2020, with which the hydromorphological changes in the Ciénaga de Aguablanca were represented. Data from six hydroclimatological stations were statistically analyzed with Pettitt’s test, trend analysis, and Rclimdex. The results indicate a reduction of 99% in the area of the wetlands, from 19.2 km2 in 1944 to 0.2 km2 by 2020. Additionally, a break point was observed in 1970, preceded by the process of wetland desiccation and waterproofing of the eastern part of Cali, along with significant differences between temperature series inside and outside the urban perimeter. Another break point was detected in 1985 in the flow series, associated with the construction of the La Salvajina dam. Monthly rainfall showed a tendency to increase, but its temporal distribution was uneven, given that rainfall volume showed a tendency to increase over short times. Regional climate changes can occur at a much faster rate than global variations due to the anthropogenic actions of wetland intervention.","PeriodicalId":49118,"journal":{"name":"Tropical Conservation Science","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/19400829211007075","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49253600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Toucans (Ramphastidae) and parrots (Psittacidae) are large-bodied primary consumers and among the most representative birds in Neotropical forests. They are highly sensitive to habitat loss; nevertheless, their response to fragmentation has been poorly assessed leading to contradictory results. Here, we evaluate the influence of landscape structure on toucans and parrots in the tropical forest of Los Tuxtlas, Mexico. Methods: We censused birds in 12 landscapes of Los Tuxtlas and used a multi-scale landscape approach to assess the influence of landscape composition and configuration on the number of individuals of toucans and parrots. Results: We found that the most important and positive predictor of toucans and parrots was the amount of primary forest cover in the landscape. Forest fragmentation had positive effects on the number of toucan individuals, whereas parrots had negative responses to patch density but positive responses to edge density in the landscape. Conclusion: Our results suggest that primary forest loss is the main threat for toucans and parrots in Los Tuxtlas. Implications for conservation: Future conservation and land management must consider the protection of large and small remnants of primary forest and avoid additional forest loss in order to preserve toucan and parrots and their functional roles in human-modified Neotropical landscapes.","PeriodicalId":49118,"journal":{"name":"Tropical Conservation Science","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49410062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing demand for pangolin fuels widespread unsustainable extraction and an illicit international trade that is threatening pangolin populations worldwide. Vietnam is an important transit country in this trafficking network and a significant consumer country, particularly due to their longstanding tradition of consuming wildlife products as traditional medicine. We conducted 51 semi-structured, questionnaire-based interviews with traditional Vietnamese medicine practitioners in Hanoi, Vietnam to explore the factors influencing their prescription of pangolin. The results show that traditional Vietnamese medicine practitioners are important drivers of pangolin use and that prescription continues despite prohibitive legislation. The main influencing factors were money, illegality (as a deterrent) and supply. Wealthier patients were more likely to use pangolin as medicine and patients generally trusted a doctor’s prescription. Awareness of regulations related to pangolin use in traditional medicine was low and pangolin use continued without fear of the law. Lactation, abscesses and circulation were the most prescribed uses for pangolin scales. All respondents believed that pangolin can be substituted, however, a belief remained that substitutes are inferior to pangolin. This study provides a unique perspective of pangolin use in one of the main pangolin consumption countries in the world. The results suggest that the law is not being implemented effectively and that increased enforcement efforts are necessary. Furthermore, these insights serve to inform future demand-reduction campaigns whereby the most common uses and substitutes for pangolin scales may be targeted.","PeriodicalId":49118,"journal":{"name":"Tropical Conservation Science","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/1940082920985755","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44510553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we used Zimbabwe as a case study to assess how different forms of media are being utilised to access information of the COVID-19 disease (across age, educational level, and employment status). We investigated people’s perceptions of the origins of COVID-19, its implication on the continued consumption of meat from wildlife species by humans, and management strategies of wildlife species that harbour the coronavirus. We gathered 139 responses using an online structured questionnaire survey. Social media platforms were used to acquire information on the COVID-19 pandemic when compared to traditional sources (television, radio, and newspapers). Most respondents thought that the COVID-19 virus was created by humans (n = 55, mostly the young and middle-aged) while others believed that it originated from animals (n = 54, mostly middle-aged with postgraduate qualifications). The majority (73%) of respondents who cited COVID-19 origin as animals also supported a ban on consumption of meat from the species. The middle-aged respondents (in comparison to the young and older respondents) and those who were employed (compared to the unemployed) were more likely to support the ban in wildlife trade. The likelihood of visiting wildlife centres given the consequences of COVID-19 was significantly lower in the old-aged respondents when compared to the young and the middle-aged respondents. Our results emphasize the need for science to penetrate social media circles to provide appropriate information. The observed perceptions about visiting wildlife centres could negatively impact conservation funding.","PeriodicalId":49118,"journal":{"name":"Tropical Conservation Science","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/19400829211008088","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43318142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mae Wong National Park in Thailand was once a haven for banteng due to its abundance of preferred habitat, but the species was extirpated in the 1970s due to logging and hunting, before park designation. Mae Wong is connected with Huai Kha Khaeng Wildlife Sanctuary (HKK), which retains the largest banteng population remaining in Thailand. In 2019, Mae Wong park rangers reported suspected banteng footprints near HKK. We used camera traps to verify the presence of banteng and determine their population structure and activity pattern. We observed at least nine individual bantengs (range 1–7 each month) during the 15-month survey, including three adult males, two adult females, three juveniles, and 1 calf. Solitary males and herds (up to five animals) were observed, reflecting typical social structure. Banteng were detected throughout the survey and across all seasons, suggesting a resident population. Our research confirms the return of banteng to Mae Wong after an absence of over 40 years. The banteng likely dispersed from HKK, emphasizing the importance of landscape connectivity and source sites for recovery of endangered species. Though still small, the Mae Wong population is breeding, which is significant for future population recovery. Protection, community outreach, and habitat management can help secure this population. As banteng is the preferred food of tigers, their recovery will benefit tiger conservation in Mae Wong as well.","PeriodicalId":49118,"journal":{"name":"Tropical Conservation Science","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45444312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the potential relationship between the trans-specific genetic diversity (or genetic diversity across tree species) and the diversity of tree species in a tropical subdeciduous forest. The nucleotide variation of the concatenated regions ITS 1 and ITS 3 (ITS1-3) was used to determine the trans-specific genetic diversity of 19 species of trees in five local communities at El Ocote Biosphere Reserve (REBISO), Chiapas, Mexico. Tree diversity was obtained by counting individual trees within 0.1 ha circular plots in each locality. The relationship between trans-specific genetic diversity and species diversity was established through simple linear regressions between genetic diversity parameters and community diversity. A correlation matrix was built with genetic distances (Kimura’s two-parameter model) and differences in species diversity between communities. A significant relationship was observed between nucleotide diversity (π) and species richness (Sp), and a negative association between haplotype diversity and gamma diversity (γ). Our results show species-rich and genetically diverse tree communities and a weak association between trans-specific genetic variation and species diversity in tree communities at REBISO. This research suggests a possible ecological and genetic relationship within each community. Genetic diversity values may provide an important degree of variation upon which environmental selection pressures could operate, which may be helpful to face the current environmental modifications associated with climatic change.","PeriodicalId":49118,"journal":{"name":"Tropical Conservation Science","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/1940082920978143","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47387437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In French Guiana, Black Curassows are heavily hunted, although basic knowledge of the ecological and demographical traits of the species remains limited. Such a gap prevents any attempt to assess the impact of hunting and to help stakeholders to develop proposals ensuring hunting sustainability. The spatial relationship between animals and their habitat is important for conservation management, being related to population densities through complex patterns. Here, we report on a radio-tracking study of Black Curassows in tropical primary rainforest, in Nouragues National Reserve, French Guiana. The aims of the study were to estimate home range size and its variation across seasons, and to quantify movement patterns of the birds. We captured and fitted VHF tags to four adults, and tracked them for 10 to 21.5 months. Daily movements were recorded, and home ranges estimated using the Kernel Density method, for two consecutive wet seasons and one dry season. Using 95% and 50% Kernel densities, the average annual home range and core area were 96.3± 32.6 ha (SE) and 22.8 ± 2.8 ha respectively. Home ranges appeared spatially stable over the two years, and overlapped between neighbouring groups. During the dry season, Black Curassows did not migrate but tended to enlarge their home range, with greater daily movements and higher home range overlap. Although additional data are still needed, our results can help to improve the knowledge and management of this poorly studied species.","PeriodicalId":49118,"journal":{"name":"Tropical Conservation Science","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48215524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
