Biotic interactions present a challenge in determining whether species distributions will track
climate change. Interactions with competitors, consumers, mutualists, and facilitators can …

Aim The factors that set species range limits underlie many patterns in ecology, evolution,
biogeography and conservation. These factors have been the subject of several reviews, but …

Determining how ecological and evolutionary processes produce spatial variation in local
species richness remains an unresolved challenge. Using mountains as a model system, we …

Extinction rates are predicted to rise exponentially under climate warming, but many of these
predictions ignore physiological and behavioral plasticity that might buffer species from …

Biodiversity is spatially organized by climatic gradients across elevation and latitude. But do
other gradients exist that might drive biogeographic patterns? Here, we show that …

Aim The scale of environmental data is often defined by their extent (spatial area, temporal
duration) and resolution (grain size, temporal interval). Although describing climate data …

Aim Species living on steep environmental gradients are expected to be especially sensitive
to global climate change, but little is known about the factors influencing their responses to …

Mountains create steep environmental gradients that are sensitive barometers of climate
change. We calibrated 10 statistical models to formulate ensemble ecological niche models …

Tropical mountains contain some of the world's richest animal communities as a result of
high turnover of species along elevational gradients. We describe an approach to study the …

Environmental gradients are instrumental in shaping the distribution and local abundance of
species because at the most fundamental level, an organism's performance is constrained …
