Approximately 25% of mammals are currently threatened with extinction, a risk that is
amplified under climate change. Species persistence under climate change is determined …

The demography of a population is often reduced to the apparent (or local) survival of
individuals and their realised fecundity within a study area defined according to logistical …

Untangling the spatial and temporal processes that influence population dynamics of
migratory species is challenging, because changes in abundance are shaped by variation in …

Contemporary climate change is expected to affect the distributions of most species, but the
nature, tempo, and mechanics of contemporary range shifts are still largely speculative …

Biotic responses to climate change will vary among taxa and across latitudes, elevational
gradients, and degrees of insularity. However, due to factors such as phenotypic plasticity …

Gene flow in natural populations may be strongly influenced by landscape features. The
integration of landscape characteristics in population genetic studies may thus improve our …

The American pika (Ochotona princeps) inhabits talus slopes on isolated mountaintops in
the Great Basin, where the species is susceptible to localized extirpations. Previous studies …

Classical ecological theory predicts that environmental stochasticity increases extinction risk
by reducing the average per-capita growth rate of populations. For sedentary populations in …

Although climate acts as a fundamental constraint on the distribution of organisms,
understanding how this relationship between climate and distribution varies over a species' …

1. Demographic analysis is essential in order to determine which factors, such as survival,
fertility and other life-history characteristics, have the greatest influence on a population's …
