Fitness results from an optimal balance between survival, mating success and fecundity. The
interactions between these three components of fitness vary depending on the selective …

Climate change and land‐use change are leading drivers of biodiversity decline, affecting
demographic parameters that are important for population persistence. For example …

Reptiles are in decline globally, and one-third of turtle species are considered endangered
or vulnerable. Conservation of turtles presents special challenges, as turtles are long-lived …

Roads impact wildlife in a variety of direct and indirect ways. Roads may act as barriers to
dispersal, lead to decreasing population size and genetic diversity, change animal behavior …

Turtles are in decline world-wide, and few studies have collected the long-term, age-specific
demographic data needed to identify species-specific life history stages critical to population …

Body size is an ecologically important variable in animals. The geographical size variation of
most snakes and some lizards counters Bergmann's rule in that, among related taxa, the …

The body condition of an animal reflects its energetic state such that an animal in good
condition has greater energy reserves than one that is in poor condition. Body condition in …

Matrix models and perturbation analyses provide a useful framework for evaluating
demographic vital rates crucial to maintaining population growth. Determining which vital …

Geographic variation in life‐history traits among populations of wide‐ranging species is
influenced by both spatial and temporal aspects of the environment. Rarely, however, are …

Wood turtles (Glyptemys insculpta) have been suffering range-wide population declines
since the 1900s. Most monitoring efforts of these turtles involve population surveys to assess …
