Approximately 2.5× 106 square kilometers of the Amazon forest are currently degraded by
fire, edge effects, timber extraction, and/or extreme drought, representing 38% of all …

As temperatures increase, there is growing evidence that species across much of the tree of
life are getting smaller. These climate change-driven size reductions are often interpreted as …

As the climate has warmed, many birds have advanced their breeding timing. However, as
climate change also changes temperature distributions, breeding earlier might increase …

Species sensitivity to forest fragmentation varies latitudinally, peaking in the tropics. A
prominent explanation for this pattern is that historical landscape disturbance at higher …

Body-size reductions are a pervasive response to climate change, and body size is a central
trait linking together multiple axes of ecology, physiology and life history. Using a …

Quantifying environment–morphology relationships is important not only for understanding
the fundamental processes driving phenotypic diversity within and among species but also …

Variation in evolutionary rates among species is a defining characteristic of the tree of life
and may be an important predictor of species' capacities to adapt to rapid environmental …

Mammals play important ecological roles in terrestrial ecosystems, with their particular
niches and their impacts on energy flow and nutrient cycling being strongly influenced by …

Insectivores of the tropical rainforest floor are consistently among the most vulnerable birds
to forest clearing and fragmentation. Several hypotheses attempt to explain this pattern …

Climate change is a global phenomenon, yet impacts on resource availability to predators
may be spatially and temporally diverse and asynchronous. As capital breeders, whales are …
