摘要: AbstractKnowledge of home ranges (HRs) helps conservationists understand movement patterns and can aid management including avoidance of human‐wildlife conflicts. This study examined the African savannah elephant seasonal HRs and space use using telemetry data in Mana Pools National Park, Zimbabwe. The objectives were to (i) compare the HR sizes and (ii) construct utilization distribution of African savannah elephants using the minimum convex polygon (MCP) method and the time‐local convex hull (T‐LoCoH). The results revealed that the dry, transitional, and wet season HR sizes estimated by the MCP method were significantly larger than those of the T‐LoCoH method. Significant differences were observed between core T‐LoCoH home‐range distributions for the wet, transition, and dry seasons. T‐LoCoH more accurately represented the HR size and nuances of repeated movements and internal spaces than the MCP method. The findings show larger‐scale movements in the transition season, which would enhance the potential for human–elephant conflicts.

摘要: Nest predation critically influences avian reproduction, with concealed nests typically assumed to be safer from nest predators. However, the expected positive relationship between nest concealment and survival has not been consistently observed across species. A hypothesis proposed by Skutch provides a possible explanation that parental care may increase nest predation risk by attracting predators. To test this hypothesis, we conducted a field experiment in the White‐bellied Redstarts (Luscinia phaenicuroides), which experience high predation rates despite highly concealed nests. Compared with active nests (with parental care), the same inactive nests after breeding had finished (without parental care) exhibited significantly higher daily survival rates and lower nest predation rates. Our findings support Skutch's hypothesis, and we presume that parental care provides cues for nest predators while the species' small body size limits nest defense. These findings provide insights into how parental behavior interacts with nest site selection to shape effective antipredator strategies.

摘要: AbstractSea turtle fibropapillomatosis (FP) is an emerging transboundary contagious disease that affected concomitantly two different marine hot spots in the Northern Atlantic Ocean and in the South China Sea at the beginning of the twentieth century. FP reached a panzootic status in the 1990s in green turtle (Chelonia mydas) populations, with increased risks of emergence and spread of the disease which have been correlated with climate induced terrestrial and oceanic physical and chemical changes. During 2023–2024, scientific experts performed a bibliographic review and recommend the consensus definition of sea turtle fibropapillomatosis. FP is an emerging transboundary viral terrestrial and aquatic contagious neoplastic syndrome involving cancerous molecular transmission pathways, which may affect all species of sea turtles at all life stages. The diagnosis of the most common verrucous form of FP is pathognomonic by visual examination of a sea turtle. We summarize the main clinical characteristics of FP, moderated by a degree of confidence of research findings adapted from the Intergovernmental Panel on Climate Change (IPCC) assessment reports. We recommend the implementation of a universal and transparent monitoring strategy of sea turtle fibropapillomatosis in sentinel bays, under the governance of the World Organisation for Animal Health.

摘要: AbstractAlthough sea turtle flipper tagging is a tenet field technique generating irreplaceable scientific data worldwide since the inception of sea turtle conservation in 1920s along the Great Barrier Reef, the procedure was reported to trigger outbreaks of sea turtle fibropapillomatosis (FP) in 2018. This global environmental impact assessment performed during 2020–2023 meta‐analyzed three impacts on sea turtles health and conservation of the presence of visible flipper tags: a risk of clinical expression of FP lesions at the tag insertion point, a deterrent effect of the presence of flipper tags on sea turtle fishing, and a risk of entanglement of sea turtles in fishing gears. This essay concluded that the risk of expression of a FP lesion at the flipper tag insertion point is most probably correlated to a direct inoculation of ChHV5 via infected tagging equipment, and that the risk of entanglement in fishing gears can be mitigated by the choice of metallic flipper tags over plastic flipper tags. This essay also strongly recalls the sea turtle flipper tagging technique represents a remedy to knowledge gaps relevant to climate velocity research and can be a deterrent on sea turtle fishing in a frame of strong partnerships with indigenous people, independently of communities' socio‐cultural backgrounds.

摘要: AbstractDespite intensified media campaigns and heightened emphasis on classroom instruction, recent international research has reported that young people are still failing to acknowledge biodiversity conservation as an issue of high priority. This study assessed students' knowledge, perception, and attitude toward biodiversity conservation in three Federal Universities offering Wildlife Management course in Southwestern Nigeria. A total of 159 respondents (15% sampling intensity) were surveyed using a structured questionnaire between July and December 2021. The findings revealed that most students had low knowledge of biodiversity conservation. This result is quite shocking given that they were enrolled in wildlife management courses. On the other hand, they had favorable attitudes and perceptions. The result further revealed that students in University of Ibadan had better attitude and perception. We concluded that there is a need to develop and teach programs and curricula that encourage and sustain the interests of wildlife students in biodiversity conservation.

摘要: AbstractHuman‐gray wolf conflict over livestock depredation and absence of mitigation measures is a key threat leading to the decline of wolf populations in Pakistan, where gray wolves are endangered. In this study, we collected data from January 2019 to September 2021, and human–wolf conflict and mitigation measures were investigated by interviews with 200 shepherds that were randomly selected from 43 different human settlements. We used binary logistic GLM models to predict landscape features related to gray wolf conflict patterns. Over the 3 years of the study, the gray wolf was responsible for 963 livestock losses and 244.50 million rupees (1,381,388.14 USD) in economic loss in summer, and 798 livestock losses along with 169.31 million rupees (956,608.1356 USD) economic loss in winter for the same 200 shepherds in Shigar valley. Our questionnaires revealed that shepherds hold negative attitudes toward the species when there is inadequate compensation by the several government department.

摘要: AbstractTo evaluate the genetic quality and provide available management strategies for Blue‐crowned laughingthrush (BCLT), fifteen polymorphic microsatellite loci were developed and applied. The genetic diversity of wild individuals was indicated to be higher than the two captive populations. The average number of alleles (5.50 ± 0.317), the number of effective alleles (3.417 ± 0.222), observed heterozygosity (0.828 ± 0.04), and genetic differentiation index (0.028 ± 0.007) of 64 wild individuals showed high genetic diversity despite drastic bottleneck and low genetic differentiation. The number of effective migrants (22.737 ± 8.318) indicated the intriguing wintering grounds may be surrounded by the breeding sites where the syncheimadia occurred in Wuyuan. Efficient conservation, winter flocking, and cooperative breeding may facilitate gene exchange and inclusive fitness. We recommend that monitoring concentrated distribution areas for BCLT should be strengthened, and geographical barriers, interference types, and the inner mechanism of distribution patterns should be further explored.

摘要: AbstractThe Chinese pangolin (Manis pentadactyla Linnaeus) is a critically endangered species that feeds on ants and termites. In 2022–2024, we observed two rescued pangolins being attacked by Solenopsis invicta Buren while in captivity. Clusters of pustules and erythema were found on the face, abdomen and limbs of the pangolin. Histopathological examination of the blistered tissue showed epithelial hyperplasia and hyperkeratosis of the skin tissue with surface crusting. In addition, we found remnants of S. invicta heads in the faeces of stung pangolins, suggesting that pangolins would feed on S. invicta. Currently, most of southern China has been invaded by S. invicta, so we conducted two S. invicta invasion surveys in pangolin habitats in Guangdong, and the results indicated that pangolin habitats in China have been invaded by S. invicta. Therefore, we suggest that S. invicta should be taken into account when developing conservation strategies for pangolins.

摘要: AbstractFlorida Fish and Wildlife Conservation Commission's Wildlife Assistance Biologists (WABs) receive calls from the public experiencing a wildlife conflict and provide guidance on how to coexist with native wildlife. This analysis considered how the number of calls and nature of calls received by WABs were impacted by COVID‐19 pandemic protective measures in Florida. Total calls to WABs decreased during COVID‐19 protective measures but did not vary significantly from the previous year. There was a significant decrease in the average weekly number of “Sick/Injured” wildlife calls and “Property Damage” calls when protective measures were in place. This analysis provides insight into how widespread changes in human mobility may impact reports of human‐wildlife conflict.
