Dominant deer mice show the importance of abundance in competition

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract Detecting competitive interactions is important for predicting species responses to environmental change but remains challenging, especially over large scales. Modern coexistence theory predicts that reduced ecological trait overlap promotes coexistence through stabilizing mechanisms, while fitness differences generate competitive asymmetries.

Alpha diversity patterns are unmatched by beta diversity across productivity gradients of the subarctic

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract The mechanisms linking productivity to patterns of species richness, species prevalence, and beta diversity remain contested and may be scale‐dependent. We address productivity–diversity relationships in arthropod communities across two subarctic landscapes.

Temperature controls bryophyte‐associated nitrogen fixation in super‐humid temperate forests in New Zealand

Ecology, Volume 107, Issue 3, March 2026.
Abstract Nitrogen (N) fixation performed by certain prokaryotes (diazotrophs) is a key source of new N in pristine ecosystems. Diazotrophs associate with various plants, including bryophytes—the dominant plant group in northern ecosystems such as boreal forests. There, bryophyte‐associated N2 fixation contribute half of total ecosystem N input. However,

Volatile Organic Compound Release During Litter Decomposition in the Arctic

Global Change Biology Communications, Volume 1, Issue 1, March 2026.
Volatile organic compound (VOC) emissions from Arctic litter decomposition decline over time and differ strongly between Cassiope tetragona and Salix arctica. The inter‐species differences and changes over time are greater than the effects of climate change treatments on litter VOC emissions.

The Importance of Spatial Variability in Estimating Evapotranspiration From a Subalpine Wetland

Hydrological Processes, Volume 40, Issue 3, March 2026.
Spatial trends in evapotranspiration were quantified in a sub‐alpine wetland, with higher rates occurring in the wetlands' western portion. This spatial variability suggests care must be taken when estimating evapotranspiration via point measurements. The METRIC approach to modelling evapotranspiration performed reasonably well and should be explored ...
