rethinking trophic niches: speed and body mass colimit prey space of mammalian predators.realized trophic niches of predators are often characterized along a one-dimensional range in predator-prey body mass ratios. this prey range is constrained by an "energy limit" and a "subdue limit" toward small and large prey, respectively. besides these body mass ratios, maximum speed is an additional key component in most predator-prey interactions.here, we extend the concept of a one-dimensional prey range to a two-dimensional prey space by incorporating a hump-shaped speed-body mass relatio ...202032760514
estimating prevalence and test accuracy in disease ecology: how bayesian latent class analysis can boost or bias imperfect test results.obtaining accurate estimates of disease prevalence is crucial for the monitoring and management of wildlife populations but can be difficult if different diagnostic tests yield conflicting results and if the accuracy of each diagnostic test is unknown. bayesian latent class analysis (blca) modeling offers a potential solution, providing estimates of prevalence levels and diagnostic test accuracy under the realistic assumption that no diagnostic test is perfect.in typical applications of this app ...202032760523
toxoplasma gondii infection in european mouflons (ovis musimon) and captive wild felines from puebla, méxico.the presence of toxoplasma gondii in zoos is cause of alert because many susceptible species kept in captivity die of clinical toxoplasmosis. moreover, excretion of t. gondii oocysts by infected captive wild felines into the facilities could pose a risk to workers. herbivores in wild collections can serve as sentinels of local transmission, since they get infected by the consumption of oocysts present in ground or water. both herbivores and felids may reveal the parasite variants which are circu ...202032760649
intergroup food transfers in wild golden lion tamarins (leontopithecus rosalia).the transfer of food between adults is uncommon in primates. although golden lion tamarins (leontopithecus rosalia) are unique among primates in the extent to which they transfer food, reports of food transfers between adults have so far been restricted to captive or reintroduced individuals. here, i report the first recorded events of adult-adult food transfers in golden lion tamarins between individuals belonging to different groups in the wild. given that individuals emigrate from their natal ...202032767132
artificial eyespots on cattle reduce predation by large carnivores.eyespots evolved independently in many taxa as anti-predator signals. there remains debate regarding whether eyespots function as diversion targets, predator mimics, conspicuous startling signals, deceptive detection, or a combination. although eye patterns and gaze modify human behaviour, anti-predator eyespots do not occur naturally in contemporary mammals. here we show that eyespots painted on cattle rumps were associated with reduced attacks by ambush carnivores (lions and leopards). cattle ...202032770111
first report on bartonella henselae in dromedary camels (camelus dromedarius).bartonellosis is one of the clinically underdiagnosed emerging bacterial diseases among domestic livestock, particularly in camels. until now, the natural infection of camels with bartonella species was not investigated in tunisia. in the attempt of filling this gap in knowledge, a total of 412 dromedary camels (camelus dromedarius) as well as 300 associated ticks (hyalomma dromedarii (160; 53.4%), h. impeltatum (131; 43.6%) and h. excavatum (9; 3%) were screened for the presence of bartonella s ...202032777455
surviving in steep terrain: a lab-to-field assessment of locomotor costs for wild mountain lions (puma concolor).under current scenarios of climate change and habitat loss, many wild animals, especially large predators, are moving into novel energetically challenging environments. consequently, changes in terrain associated with such moves may heighten energetic costs and effect the decline of populations in new localities.202032782806
ecological drivers of female lion (panthera leo) reproduction in the kruger national park.the role of social cues in the reproduction of social mammals, particularly carnivores, has been thoroughly studied and documented in literature. however, environmental cues such as resources of water, food, and shelter have been identified to a lesser extent. pregnant lions (panthera leo) are notoriously secretive during the final stages of pregnancy and postpartum. behavioral indicators depicted by movement patterns obtained by remote detection of collared female lions in the kruger national p ...202032788956

sylvatic canine morbillivirus in captive panthera highlights viral promiscuity and the need for better prevention strategies.canine distemper virus (cdv) is a multi-host morbillivirus that infects virtually all carnivora and a few non-human primates. here we describe a cdv outbreak in an exotic felid rescue center that led to the death of eight felids in the genus panthera. similar to domestic dogs and in contrast to previously described cdv cases in panthera, severe pneumonia was the primary lesion and no viral antigens or cdv-like lesions were detected in the central nervous system. four tigers succumbed to opportun ...202133946447
respiratory tract explant infection dynamics of influenza a virus in california sea lions, northern elephant seals, and rhesus macaques.to understand susceptibility of wild california sea lions and northern elephant seals to influenza a virus (iav), we developed an ex vivo respiratory explant model and used it to compare infection kinetics for multiple iav subtypes. we first established the approach using explants from colonized rhesus macaques, a model for human iav. trachea, bronchi, and lungs from 11 california sea lions, 2 northern elephant seals, and 10 rhesus macaques were inoculated within 24 h postmortem with 6 strains r ...202134037419
activation of nf-κb and induction of proinflammatory cytokine expressions mediated by orf7a protein of sars-cov-2.severe acute respiratory syndrome coronavirus 2 (sars-cov-2) is the causative agent for coronavirus disease 2019 (covid-19) that emerged in human populations recently. severely ill covid-19 patients exhibit the elevation of proinflammatory cytokines, and such an unbalanced production of proinflammatory cytokines is linked to acute respiratory distress syndrome with high mortality in covid-19 patients. our study provides evidence that the orf3a, m, orf7a, and n proteins of sars-cov-2 were nf-κb a ...202134188167
covid-19 suppression of human mobility releases mountain lions from a landscape of fear.humans have outsized effects on ecosystems, in part by initiating trophic cascades that impact all levels of the food chain.1,2 theory suggests that disease outbreaks can reverse these impacts by modifying human behavior,3,4 but this has not yet been tested. the covid-19 pandemic provided a natural experiment to test whether a virus could subordinate humans to an intermediate link in the trophic chain, releasing a top carnivore from a landscape of fear. shelter-in-place orders in the bay area of ...202134197728
in vitro characterization of fitness and convalescent antibody neutralization of sars-cov-2 cluster 5 variant emerging in mink at danish farms.in addition to humans, severe acute respiratory syndrome coronavirus 2 (sars-cov-2) can transmit to animals that include hamsters, cats, dogs, mink, ferrets, tigers, lions, cynomolgus macaques, rhesus macaques, and treeshrew. among these, mink are particularly susceptible. indeed, 10 countries in europe and north america reported sars-cov-2 infection among mink on fur farms. in denmark, sars-cov-2 spread rapidly among mink farms and spilled-over back into humans, acquiring mutations/deletions wi ...202134248922
