Summary: The study found that lethal removal of wild pigs via trapping can significantly reduce pig density at some sites, with a qualitative reduction observed at other sites. There was little evidence of shifts in pig home-ranging behavior following removal, but a nuanced response in movement behavior was observed at a fine-scale level. This research provides insights into the impact of trapping on wild pig movement and its management implications, demonstrating how targeted trapping can temporarily alleviate the pressure on species sensitive to wild pig consumption.

Summary: Understanding the home range, spatial patterns, and habitat use of wild boar is crucial for effectively managing their population. This study examined the impact of crop harvesting on habitat selection of wild boar in an agricultural landscape in Poland. The results showed that wild boar exhibited monthly dynamics in their preference for arable land, pastures, forests, and mosaics. The preference for arable land decreased significantly in August, likely due to the impact of harvesting. Intensive agriculture was found to significantly affect the frequency of wild boar in different habitats, while forest habitats remained their main daytime refuge. Extensive farming, on the other hand, had a neutral effect on the abundance of wild boar in habitats.

Summary: This study compared cortisol levels in wild boars caught in corral-style traps with those killed during other hunting methods and found that cortisol levels were higher in wild boars killed in traps. Wild boars caught in larger groups showed lower cortisol levels, indicating reduced stress. To minimize stress, it is recommended to minimize the time spent inside the trap and to capture larger groups of animals. However, additional data from behavioral analyses and pathological examinations are necessary for a comprehensive assessment of animal welfare in live-trapping wild boars.

Summary: Quantifying feral pig movements and understanding their preferences for specific habitat features are crucial for optimizing pest management programs. In this study, we tracked 59 GPS-collared feral pigs in eastern Australia and analyzed their activity patterns and habitat use. We found that male pigs traveled significantly longer distances than females and were active throughout the night, while female activity was concentrated during dusk and dawn. The selection of highly visited sites was influenced by proximity to water sources, cultivated areas, and certain vegetation types. Quantifying feral pig activity and habitat preferences can greatly improve management strategies by allowing more targeted control measures.

Summary: This study evaluated the imputation of ancient Sus scrofa genomes and found that the accuracy of imputation is affected by factors such as genetic architecture and divergence in the reference panel. Despite achieving high genotype concordance, the imputed genotypes did not fully capture the diversity present in the original genomes, leading to biases in downstream analyses.

Summary: This study found that giant anteaters reduce displacement and increase forest use with decreasing environmental temperature, likely due to their low heat production. Forest habitats provide warmer conditions and shelter from rain and wind. Decreasing movement is a strategy to reduce energy costs, but it may also limit food access and fitness.

Summary: Territoriality is common in the animal kingdom, but the evolutionary origins of movement patterns related to it remain less understood. Previous studies identified four competing strategies for movement patterns in territorial animals: Cautious, Common-sense, Paradoxical, and Daring. Contrary to previous literature, it was found that the Cautious strategy was evolutionarily stable in terms of winning resources and invading populations of other strategies.

Summary: Small felids, including Leopardus guttulus, can have a direct influence on the organization of small Neotropical vertebrate communities. This study found that the southern tiger cat's diet consists of a high diversity of different prey species, consumed per their availability, and selected according to mass and accessibility. In the area devoid of other felid competitors and with abundant prey, the S-tiger cat seems to consume prey species within a relatively narrow mass spectrum.

Summary: The niche of a species is determined by ecological and evolutionary factors. Species that are closely related may either retain ancestral ecological characteristics or differentiate themselves to reduce niche overlap and facilitate coexistence. In this study, we investigated the niche of two closely related reef fish species in southern Brazil, finding differences in thermal distribution and abundance but not in microhabitat preferences. Despite considerable niche overlap, the two species are successfully coexisting, possibly due to their evolutionary history.

Summary: The study examined the feasibility of using a fixed-wing UAS equipped with a thermal infrared sensor for estimating the population density of wild white-tailed deer in Minnesota, USA. Comparisons were made between UAS density estimates and those derived from faecal pellet-group counts. The results showed that UAS yielded similar results to pellet-group counts for estimating population densities of wild ungulates, with the added benefit of being more efficient and able to be conducted at multiple times throughout the winter.

Summary: This study developed a new approach to estimate capybara roadkill hotspots in the big city of Campo Grande, Brazil, and investigated driving factors correlated with roadkill occurrences. The analysis revealed hotspots around large green areas and water bodies where capybara habitat and physiological requirements are likely met. The predictive map identified latent hotspots that have the necessary characteristics for capybaras to live but where observed deaths have not occurred. Speed reduction tools around parks are recommended to mitigate the risk. Reducing capybara roadkills could have a positive impact on human population welfare and material damage caused by collisions.

Summary: Current methods for predicting isotopic variation at regional scales lack consideration of the underlying distribution of isotopic substrates. Traditional kriging methods also ignore potential influences of environmental grouping factors, resulting in higher prediction error. In this study, we aimed to improve isoscape modeling techniques by accounting for isotopic substrate abundances and implementing a mixed-effects, regression kriging approach. Our findings demonstrate how field-collected data, geospatial information, and novel interpolation techniques can enhance the accuracy of isotopic landscape estimation.
