Over the past decade, a significant increase in the circulation of infectious agents was
observed. With the spread and emergence of epizootics, zoonoses, and epidemics, the risks …

Conservation physiology proposes that measures of physiological stress (glucocorticoid
levels) can be used to assess the status and future fate of natural populations. Increases in …

Trade-offs and constraints are inherent to life, and studies of these phenomena play a
central role in both organismal and evolutionary biology. Trade-offs can be defined …

Abstract Evaluation of physiological stress in the tiger (Panthera tigris) using faecal cortisol
metabolite (FCM) enzyme immunoassays (EIAs) provides a powerful conservation …

Humans have always been plagued by epidemics caused primarily by infectious diseases
that originated from animals, especially wildlife (1). The establishment of sustained …

The dynamics of infectious diseases can be affected by genetic diversity within host
populations, species diversity within host communities, and diversity among communities. In …

Reptiles are ectothermic amniotes, providing the key link between ectothermic anamniotic
fishes and amphibians, and endothermic amniotic birds and mammals. A greater …

The field of stress physiology has rapidly expanded, particularly in those fields interested in
identifying chronic stress in wild animals. Despite this expansion, stress remains difficult to …

Environmental change has negatively affected most biological systems on our planet and is
becoming of increasing concern for the well-being and survival of many species. At an …

Human‐induced landscape change associated with habitat loss and fragmentation places
wildlife populations at risk. One issue in these landscapes is a change in the prevalence of …
