Abstract In south Florida, white‐tailed deer (Odocoileus virginianus) are the primary prey of the endangered Florida panther (Puma concolor coryi). Deer populations in some regions of south Florida have declined in recent years, and the role of fawn survival and recruitment in these declines is unknown. Determining known‐fate survival of fawns is c...

Fine‐scale monitoring of neonate mammals can provide important data about survival rates and cause‐specific mortality. However, the VHF transmitters and collars frequently used to monitor neonate mammals necessitate logistically intensive field efforts, often requiring personnel to check on collared animals several times a day. We adapted technolog...

Adult, free-ranging cougars (Puma concolor) were sampled in three regions of Utah, US, from 2018 to 2021. A total of 68% (23/34) of the sampled cougars had antibodies to feline parvovirus, 15% (5/33) to canine distemper virus, 18% (6/34) to calicivirus, and 22% (8/37) to Yersinia pestis. Forty-one percent (13/32) had IgG antibodies to Toxoplasma go...

Large carnivore restoration programs are often promoted as capable of providing ecosystem services. However, these programs rarely measure effects of successful restoration on other economically and ecologically important species. In South Florida, while the endangered Florida panther Puma concolor coryi population has increased in recent years due...

Conservation and management efforts have resulted in population increases and range expansions for some apex predators, potentially changing trophic cascades and foraging behavior. Changes in sympatric carnivore and dominant scavenger populations provide opportunities to assess how carnivores affect one another. Cougars (Puma concolor) were the ape...

Understanding the factors influencing recruitment in animal populations is an important objective of many research and conservation programmes. However, evaluating hypotheses is challenging because recruitment is the outcome of birth and survival processes that are difficult to directly observe. Capture–recapture is the most general framework for e...

Although theory suggests that hybrid zones can move or change structure over time, studies supported by direct empirical evidence for these changes are relatively limited. We present a spatiotemporal genetic study of a hybrid zone between Pseudacris nigrita and P. fouquettei across the Pearl River between Louisiana and Mississippi. This hybrid zone...
