Wild animals experience different challenges and opportunities as they mature, and this
variety of experiences can lead to different levels of welfare characterizing the day‐to‐day …

Background The vertebrate gut microbiome (GM) can vary substantially across individuals
within the same natural population. Although there is evidence linking the GM to health in …

Telomeres have been advocated to be important markers of biological age in evolutionary
and ecological studies. Telomeres usually shorten with age and shortening is frequently …

Chronic, low‐intensity parasite infections can reduce host fitness through negative impacts
on reproduction and survival, even if they produce few overt symptoms. As a result, these …

Simple Summary Avian haemoproteids are prevalent parasites known to induce pathology
or mortality in birds. Culicoides biting midges act as vectors for these parasites. Despite the …

Understanding where genetic variation exists, and how it influences fitness within
populations is important from an evolutionary and conservation perspective. Signatures of …

Aim The role of migratory birds in the spread of parasites is poorly known, in part because
migratory strategies and behaviours potentially affecting transmission are not easy to study …

Prevalence responses to anthropic factors differ across hosts and parasite species. We here
analyzed the spatiotemporal variation of avian haemosporidian prevalence in bird …

Senescence is defined as the general deterioration of the organism (ie physiology,
morphology, reproduction), and is associated with increasing mortality and decreasing …

Background The prevalence of avian haemosporidian parasites and the factors influencing
infection in the Colorado Rocky Mountains are largely unknown. With climate change …
