Summary: For some species, roadkill does not occur in hotspots but is instead dispersed along the roads. Traditional management measures may not be effective for mitigating the number of roadkill incidents, so temporary mitigation actions like traffic calming could be implemented. This study tested the feasibility of predicting seasonal peaks of roadkill using data from a 3-year monitoring in Brazil. The results suggest that it is possible to forecast periods of higher probability of roadkill incidents, providing valuable information for seasonal management actions.

Summary: Our study reveals that inbreeding depression severely impacts multiple life-history stages of the Guam kingfisher, directly affecting population viability under different management options. Simulations incorporating our inbreeding depression estimates show rapid population decline, emphasizing the importance of considering this factor in conservation decisions to prevent species extinction and support wild releases. Incorporating inbreeding depression across life-history stages can significantly influence demographic outcomes and inform effective conservation management strategies.

Summary: This study introduced a framework to quantify the impact of roadkill on terrestrial mammals globally. It identified populations of threatened species that require special attention and revealed regions where vulnerable species are at risk due to high road densities, particularly in South Africa, central and Southeast Asia, and the Andes.

Summary: This study examines the genomic consequences of an extreme bottleneck and subsequent translocation in the Chatham Island black robin. The results show a decline in heterozygosity and an increase in inbreeding in modern genomes compared to historical genomes. The translocation had only small effects on the frequency of deleterious alleles, with most detrimental variation being shared between populations.

Summary: This article investigates the influence of purging on the establishment of a minimum viable population (MVP) for long-term survival. Computer simulations were used to study extinction times and loss of genetic diversity for different effective population sizes. The results indicate that purging can reduce the MVP needed for a population to persist in the long term, especially for species with higher reproductive rates.

Summary: Human-driven habitat fragmentation and loss have resulted in small and isolated plant and animal populations facing high risk of extinction, mainly due to inbreeding depression. While the traditional approach for managing these populations involves maintaining high genetic diversity, recent research suggests that minimizing strongly deleterious variation may be more important in reducing extinction risk.

Summary: Conservation genetics aims to evaluate population health and extinction risk based on genetic diversity levels, but neutral genetic diversity is not the only factor affecting species extinction risk. A deeper understanding of functional genetic diversity, demographic history, and ecological relationships is necessary for developing effective conservation genetic strategies.

Summary: The use of genomic data allows for more accurate assessment of inbreeding level and depression. Genome-based inbreeding coefficients show stronger correlations with pedigree-based inbreeding coefficients, particularly those based on runs of homozygosity (ROH) segments and heterozygosity by descent segments (HBD). Genome-based inbreeding coefficients have more significant effects on reproductive traits compared to pedigree-based inbreeding coefficients.

Summary: Rapid environmental change poses a significant challenge to natural populations, and evolutionary rescue can prevent extinction by enabling rapid adaptation. This study found that the demographic history of populations plays a crucial role in evolutionary rescue. Populations without a history of bottleneck avoided extinction entirely, whereas more than 20% of populations with an intermediate or strong bottleneck went extinct. These results emphasize the importance of considering population history when making conservation decisions and management strategies to address environmental change.

Summary: This article explores the influence of genetic problems on the estimation of minimum viable population size, and proposes corresponding methods and models. The study finds that the interaction of genetic problems significantly affects the size of minimum viable population, and the size changes rapidly with increasing mutation rates or number of loci. Further empirical studies are needed to reveal the interaction of different genetic processes in the genome.

Summary: By combining data from CALIPSO and MERRA-2, the study characterized aerosol cross-boundary transport in the Edmonton-Calgary Corridor from 2011 to 2017. Results indicated that the western and norther boundaries were the main aerosol importing gateways, while the eastern boundary tended to export aerosols. In summer, the southern boundary showed more efficient aerosol importing, contributing to the outbreak of wildfires in the Pacific Northwest.

Summary: This study investigates the genomic consequences of long-term isolation and small population size in the Svalbard reindeer, an endemic subspecies that has adapted to the High Arctic. The results show that long-term isolation and high inbreeding levels have led to a reduction in deleterious variation. However, the study also suggests that severely bottlenecked populations can still retain evolutionary potential.

Summary: Projections about the future condition of a species, generated using population viability analysis (PVA) or other analytical techniques, are important for conservation decisions. The three Rs (resiliency, redundancy, and representation) are used to evaluate these projections for listing decisions under the US Endangered Species Act. However, explicit linkage of PVA outcomes to the three Rs is rare.

Summary: This study analyzed a section in the Junggar Basin of northwest China and proposed a link between the end-Triassic mass extinction and the eruption of the Central Atlantic Magmatic Province (CAMP), as well as wildfires. The results suggest that widespread deforestation caused by CAMP-derived acid rain may have led to the rapid and large-scale demise of vegetation, providing fuel for wildfires.

Summary: Firebrands are commonly observed in wildland fires, capable of traveling long distances and igniting spot fires in the wildland-urban interface. The minimum sound pressure required to extinguish the firebrand flame decreases significantly as the velocity of the firebrand increases.

Summary: The study investigated the impact of new records on the potential distribution of Histiotus velatus over decades, finding that the predicted area expanded and retracted with the addition of new occurrences. The accuracy of models improved with time, despite most records being located in the southeastern region of Brazil.

Summary: Restingas are coastal ecosystems in the Atlantic forest characterized by diverse sandy soil vegetation. Human activities have had a negative impact on these areas, resulting in loss or degradation. However, our knowledge of bat species and their conservation status in restingas is limited. In this study, we examined bat community composition and geographic distance among 17 restingas in Brazil. The results showed no correlation between geographic distance and species composition similarity among restingas. Despite some attention, restingas have been undersampled, leading to a lack of understanding of their biological importance.

Summary: Diet plays an important role in a species' vulnerability to extinction. Primates with high diet diversity and disparity are less prone to extinction. The degree of dietary specialization of a species can guide studies on extinction risk and threats, and be useful in species assessments.
