A Seismically Active Shear Zone in the Uppermost Mantle Beneath the Canadian Rockies

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Continental mantle earthquakes are uncommon but hold important clues for understanding lithospheric rheology. Few of these earthquakes (<10) have been documented in western North America, though it is likely more exist owing to difficulties in resolving focal depth for small earthquakes.

Life on the Edge: Ecosystem Features of Lakes Across a Mountain–Prairie Elevation Gradient in Western Canada

open access: yesEcohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT Ecological transition zones such as mountain elevation gradients can influence the function and productivity of lakes through changes in climatic characteristics and catchment composition (i.e., land use/land cover). However, surveys of limnological features along such ecological transition zones show variable patterns, making it difficult to ...

Effects of emergency winter supplemental feeding on survival of mule deer

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 1, January 2026.
Abstract Ungulates in temperate regions can experience high mortality during severe winters, which poses significant ecological and economic challenges for wildlife managers. To mitigate these effects, emergency winter‐feeding programs are often implemented, although their effectiveness remains uncertain.

Plant conservation in a changing Mediterranean world

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 49-72, January 2026.
The Mediterranean is one of five climatic regions on the planet characterised by a prolonged summer drought, exceptional plant diversity and high rates of endemism. We provide a framework to link the ecology of plant species conservation in the context of rapid and extreme climate deregulation to a philosophical typology of temporal attitudes (i.e ...

Inverse effects of soil moisture and litter quality on litter decomposition along a gradient from hyper‐arid to temperate climate

open access: yesJournal of Ecology, Volume 114, Issue 1, January 2026.
We hypothesized that litter decomposition (H1) and litter quality (H2) increase with increasing soil humidity, therefore litter from the wetter sites to have the highest litter quality and decompose fastest in each site, and fastest on the wet end of the gradient (H3).
