The amount of habitable area available to American black bears has been drastically reduced, especially in the southeastern United States, causing some populations to face possible extirpation. Nonetheless, some Black Bear populations have begun to recover and recolonize portions of historic Black Bear range, despite human-dominated landscapes. The relationship between Black Bear population expansion and human development is especially apparent in Alabama. Our study makes predictions of the potential for population range expansion of black bears in Alabama. We created resource selection models for black bears via a Geographic Information System and location data from GPS-collared black bears. Our models suggested that there are areas of Alabama that could provide opportunities for population growth, allowing bear populations to expand toward their historic distribution. Understanding potential bear population expansion in Alabama could help to inform wildlife managers who are seeking to enhance bear populations and prepare for potential bear population growth in the state and elsewhere in the United States.</p>","PeriodicalId":50157,"journal":{"name":"Journal of Mammalogy","volume":"106 4","pages":"965-975"},"PeriodicalIF":1.6,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12341860/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144849540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wild pigs (<i>Sus scrofa</i>) are a highly detrimental invasive species in North America, directly and indirectly affecting native species. Co-occurrence of wild pigs and native species may lead to interspecific interactions that alter ecological communities. Accordingly, we investigated spatial and temporal factors influencing detection and occupancy of Eurasian Wild Pig and Nine-banded Armadillo (<i>Dasypus novemcinctus</i>) before examining interspecific effects. We analyzed camera-trap data collected from August to September 2021 using a hierarchical modeling framework to estimate detection and occupancy of both species individually (single-species analyses) and concurrently (conditional co-occurrence analyses). We observed higher Wild Pig detection rates and space use in late summer and in areas with greater riparian cover, respectively. Armadillo detection increased linearly throughout our sampling season and in response to precipitation. Moreover, armadillo detection was 3.5 to 5.1× higher at sites used by wild pigs, regardless of whether wild pigs were detected during a survey period. Occupancy of armadillo was best explained by a quadratic trend in site elevation but did not depend on the presence of wild pigs. Our results indicate that wild pigs may influence armadillo detection (or site-use intensity), but not occupancy, therefore revealing nuanced interspecific interactions. Between species, we observed high overlap in diel activity but significantly different activity peaks, with armadillos being strictly nocturnal and wild pigs being crepuscular but with more cathemeral activity, suggesting that fine-scale temporal partitioning may have occurred. Our results provide insights into the influence of a large-bodied and destructive invasive species (Wild Pig) on a smaller, ecologically important native species (Nine-banded Armadillo).</p>","PeriodicalId":50157,"journal":{"name":"Journal of Mammalogy","volume":"106 4","pages":"976-988"},"PeriodicalIF":1.6,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12341870/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144849539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

African leopards (<i>Panthera pardus</i>) are listed as vulnerable, with declining populations. However, population size estimates are rare for much of their range. Here, we provide population size estimates for leopards in the Limpopo (LNP) and Banhine (BNP) national parks and the Lebombo Conservancy (LC), in western Mozambique. We estimate population sizes using SNP-based CMR models derived from genetic information acquired noninvasively from scats collected across the sites.

We estimate populations of 87, 15, and 13 leopards in LNP, BNP, and LC, respectively. Population size estimates derived from trophic scaling suggest that leopards are limited by bottom-up prey resources in LNP and LC, but there is evidence for top-down regulation in BNP.

This divergence appears to occur when subadult males are approaching adulthood. However, no difference in body weight or total body length was observed between the sexes. Using these data, we established approximate size ranges for wombats of all age cohorts to underpin future research on the impacts of rainfall and drought on body condition, breeding, recruitment, and survival in this semiarid dwelling species.
