Retrogressive Thaw Slumps Produce a Changing Disturbance Regime for Arctic Stream Invertebrates

open access: yesGlobal Change Biology, Volume 32, Issue 3, March 2026.
Climate change is causing permafrost to thaw, resulting in the formation of large craters in the ground called thaw slumps, which deposit sediments and nutrients into rivers and continually impact stream ecosystems over time. We returned to slump impacted streams 10 years after an initial sample period and found that slumps permanently change streams ...

Diversification and Evolutionary Dynamics in Tropical Montane Regions

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 3, March 2026.
ABSTRACT Aim The evolution of montane species provides critical insights into the drivers of adaptation and diversification. Topographic complexity, a defining feature of many mountainous landscapes, promotes ecological and geographic isolation, often accelerating speciation rates.

Assessment and Prediction of the Effects of Flooding on Road Infrastructure Using a GIS‐Ensemble Modeling Approach: A Case Study of Mai Mahiu‐Narok Road, Kenya

open access: yesJournal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT Roads are ecologically sensitive infrastructure that are highly susceptible to flooding, which can impair their functionality, serviceability, and durability. Existing assessment methods are often subjective or lack the ability to incorporate domain‐specific knowledge. Therefore, approaches that integrate expert‐driven prioritization with data‐

Pleistocene Smoothing and Resurfacing of Appalachian Ridgelines by Periglaciation

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Pleistocene cold periods created widespread periglacial conditions across mid‐latitudes, but isolating their geomorphic impact from modern climate, tectonics, and rock strength is challenging. We studied Appalachian (Eastern U.S.) ridgelines across a paleoclimate gradient, controlling for bedrock and structure, to test if colder periglacial ...
