Unraveling the role of environmental and anthropogenic drivers in shaping global patterns in mammal diversity

open access: yesEcography, EarlyView.
Patterns in functional and phylogenetic diversity reflect ecological and evolutionary relationships among taxa, and thus can offer key insights into the mechanisms underlying species distributions. However, disentangling the relative influence of proximate environmental drivers versus biogeographic evolutionary history can be a challenge.

Patterns and drivers of biotic disturbance hotspots in western United States coniferous forests

open access: yesEcography, EarlyView.
Globally, forest disturbances caused by herbivorous insects and plant pathogens (i.e. biotic disturbances) have increased since the 1990s, a trend linked in part to climate warming. With increases in biotic disturbance activity, an emerging ecological phenomenon has been documented: biotic disturbance ‘hotspots', or areas where two or more biotic ...

Living in the edge: demographic responses driven by density‐dependence and pulsed resources in a hibernating mammal

open access: yesEcography, EarlyView.
Populations at the edge of a species' distribution often encounter more challenging environmental conditions than those at the core, requiring unique adaptations and strategies. However, the demographic processes driving these populations remain poorly understood.

A test of the abundant‐center hypothesis for stream fishes

open access: yesEcography, EarlyView.
The abundant‐center hypothesis (ACH) provides a conceptual model for predicting range‐wide distributions of species abundance, suggesting that abundance peaks in the center of the geographic range and declines towards range edges. Empirical studies testing the ACH and its subsequent derivations predominantly occurred in terrestrial systems and reported
