Global Diversification Rates of Ferns Across Spatial and Climatic Gradients

Advanced Science, Volume 13, Issue 3, 14 January 2026.
Diversification rates of fern genera across the phylogeny. Abstract Geographic patterns of diversity in any group of plants are the result of the interplay of environmental conditions and the evolutionary dynamics of the respective plant group. Here, the geographic distribution of current mean diversification rates (MDR) is explored at the genus level ...

Does the abiotic environment influence the distribution of flower and fruit colors?

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

A Decade of Post‐Fire Succession Amplifies the Effect of Wildfire on the Surface Radiation Balance and Permafrost Thaw in Subarctic Peatlands

Permafrost and Periglacial Processes, Volume 37, Issue 1, Page 124-142, January/March 2026.
ABSTRACT Increasing wildfire activity is driving permafrost thaw in subarctic peatlands across the southern Northwest Territories, but the key mechanisms and progression of thaw following fire remain poorly understood. In response, 10 years (2015–2024) of near‐continuous surface (four‐component radiation, wind, and snow) and subsurface measurements ...

Under‐Ice Ecological and Biogeochemical Dynamics at the Onset of Spring Thaw in Four Arsenic‐Contaminated Subarctic Lakes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Interactions between aquatic organisms and contaminants in under‐ice lake environments are poorly characterized relative to ice‐free seasons. Here, we compared under‐ice arsenic biogeochemical processes and plankton community composition in four subarctic lakes spanning an arsenic contamination gradient.

Arctic geese in newly colonised, colder breeding areas have higher spring body mass and breed earlier relative to the onset of spring

Journal of Animal Ecology, Volume 95, Issue 1, Page 97-114, January 2026.
Moving to colder areas allows arctic geese to reduce the negative effects of climate change (trophic mismatch), but this comes at a price for parents as they face harsher nesting conditions (snow cover), which only parents capable of large investments can cope with: climate change effects differ between individuals within populations.
