Most mammals do not wander: few species escape continental endemism

Ecography, EarlyView.
Terrestrial mammals are found nearly everywhere on Earth. Yet, most taxa are endemic to a single continent; geological, evolutionary, ecological, or physiological filters constrain geographic distributions. Here, we synthesize data on geography, taxonomy, lineage age, dispersal, body size, and diet for > 4000 terrestrial mammals prior to detectable ...

Ecography, EarlyView.
Habitat is a key aspect of any species' niche and can affect populations at multiple spatial scales. Basic ecology and effective conservation thus require an understanding of which habitats matter and at what scales. Yet, habitat studies are rarely scale‐optimized, and what determines the scale(s) at which populations are affected by surrounding ...
