Host species that can independently maintain a pathogen in host community and contribute to infection other are important targets for disease management. However, the potential of is not fixed over time, an challenge understanding how within- across-season variability maintenance affects persistence longer time scales relevant management (e.g., years). Here, we sought understand causes consequences seasonal dynamics leopard frogs (Rana sphenocephala Rana pipiens) infected with fungal...
Accurately predicting the impacts of climate change on wildlife health requires a deeper understanding seasonal rhythms in host-pathogen interactions. The amphibian pathogen, Batrachochytrium dendrobatidis (Bd), exhibits seasonality incidence; however, role that biological host defences play defining this pattern remains largely unknown. aim study was to examine whether immune and microbiome against Bd correspond with infection risk fluctuations temperature humidity. Over course year, five...
Abstract Climate change is increasing variability in precipitation patterns many parts of the globe. Unpredictable changes water availability can be particularly challenging for organisms that rely on precipitation‐fed sources completing their life cycle, such as amphibian species. Although developmental plasticity mitigate impacts changing environments some species, this strategy come at a cost to other fitness‐linked traits, immune function. We investigated localized variation capacity...
Antimicrobial peptides (AMPs) play a fundamental role in the innate defense against microbial pathogens, as well other immune and non-immune functions. Their amphibian skin pathogenic fungus Batrachochytrium dendrobatidis (Bd) is exemplified by experiments which depletion of host's stored AMPs increases mortality from infection. Yet, question remains whether there are generalizable patterns negative or positive correlations between AMP defenses probability infection intensity across...
Biological systems are likely to be constrained by trade-offs among robustness, resilience, and performance. A better understanding of these is important for basic biology, as well applications where biological can designed different goals. We focus on redundancy plasticity mechanisms governing some types trade-offs, but mention others well. Whether due resource constraints or "design" (i.e., structure nodes links within a network) will also affect the that important. Identifying common...
Hosts may limit exposure to pathogens through changes in behaviour, such as avoiding infected individuals or contaminated areas. Here, we tested for a behavioural response ranavirus infection juvenile wood frogs ( Rana sylvatica ) because the majority of dispersal between populations occurs during this life stage. We hypothesized that if infections are transmissible and detectable at stage, then susceptibles would display avoidance behaviours when introduced an conspecific. Despite no...
Detecting and quantifying pathogens with quick, cost-efficient sensitive methods is needed across disease systems for addressing pertinent epidemiological questions. Typical rely on extracting DNA from collected samples.
