Abstract Headwater catchments provide essential water and nutrients to downstream ecosystems. The timing and evolution of their transport is shaped in part by the “invisible” subsurface structure but have been largely unexplored at the watershed scale.

Sympatry Increases Predation Risk for an Endangered Ungulate
We characterized predation risk for Peninsular bighorn sheep and southern mule deer across their ranges to understand how topography, habitat, forage, and prey habitat suitability affect where pumas are likely to predate both species. The presence of the second ungulate species increased predation risk for both species but had the greatest effect on ...

A primer on forest structure measurement with lidar for ecologists
Abstract Light detection and ranging (lidar) technology has fundamentally advanced the way we measure forest structure, facilitating new insights into ecological processes. Lidar for forest ecology applications is deployed on multiple types of platforms that operate from the ground, air, or space, and each has associated strengths and limitations ...

Land cover and elevation are shown to influence the proportion of stream source waters across glacial and non‐glacial streams. Groundwater makes up a large proportion of both early season and late season flow in most glacial and non‐glacial streams, while the timing of snow and ice melt is driven by the presence or absence of a glacier within the ...
