Spillover of viruses from bats to other animals may be associated with increased contact between them, as well shedding by bats. Here, we tested the prediction that little brown (Myotis lucifugus) co-infected M. lucifugus coronavirus (Myl-CoV) and Pseudogymnoascus destructans (Pd), fungus causes bat white-nose syndrome (WNS), exhibit different disease severity, viral molecular responses than infected only Myl-CoV or P. destructans. We took advantage natural persistence in were experimentally...
Understanding how context (e.g., host species, environmental conditions) drives disease susceptibility is an essential goal of ecology. We hypothesized that in bat white-nose syndrome (WNS), species-specific host–pathogen interactions may partly explain varying outcomes among species. characterized and pathogen transcriptomes paired samples lesion-positive lesion-negative wing tissue from bats infected with Pseudogymnoascus destructans three parallel experiments. The first two experiments...
Little is known about skin microbiota in the context of disease white-nose syndrome (WNS), caused by fungus Pseudogymnoascus destructans (Pd), that has enormous declines hibernating North American bats over past decade. Interestingly, some species, such as big brown bat (Eptesicus fuscus), appear resistant to and their could play a role. However, comprehensive analysis E. fuscus Pd not been done. In January 2017, we captured fuscus, sampled microbiota, inoculated them with or sham inoculum....
Dive characteristics and dive shape are often used to infer foraging success in pinnipeds. However, these inferences have not been directly validated the field with video, it remains unclear if this method can be applied benthic animals. This study assessed ability of from time-depth recorders (TDR) predict attempted prey capture events (APC) that were observed on animal-borne video Australian fur seals (Arctocephalus pusillus doriferus, n=11). The most parsimonious model predicting...
Abstract White-nose syndrome (WNS) is an emergent wildlife fungal disease of cave-dwelling, hibernating bats that has led to unprecedented mortalities throughout North America. A primary factor in WNS-associated bat mortality includes increased arousals from torpor and premature fat depletion during winter months. Details species sex-specific changes lipid metabolism WNS are poorly understood may play important role the pathophysiology disease. Given likely fact liver plays a crucial fatty...
Knowledge of the factors shaping foraging behaviour species is central to understanding their ecosystem role and predicting response environmental variability. To maximise survival reproduction, strategies must balance costs benefits related energy needed pursue, manipulate, consume prey with nutritional reward obtained. While such information vital for how changes in assemblages may affect predators, determining these components inherently difficult cryptic predators. The present study used...
White-nose syndrome (WNS)-positive little brown bats (Myotis lucifugus) may exhibit immune responses including increased cytokine and pro-inflammatory mediator gene levels. Bioactive lipid mediators (oxylipins) formed by enzymatic oxidation of polyunsaturated fatty acids can contribute to these responses, but have not been investigated in WNS pathophysiology. Nonenzymatic conversion also occur due reactive oxygen species, however, enantiomeric isomers will lack the same signaling properties....
