Transient shifts in Bering Sea shelf phytoplankton size structure in response to wind‐induced mixing
Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.Abstract Phytoplankton community size structure is a key attribute that influences pelagic trophic energy transfer and the vertical flux of organic matter to benthic food webs. To capture the ephemeral scale of phytoplankton population size spectra we developed an approach, combining long‐term survey datasets, machine learning modeling and 3 yr of high‐

Biome Specialisation in Squirrels: Phylogenetic and Geographic Patterns
Journal of Biogeography, Volume 53, Issue 1, January 2026.ABSTRACT Aim Habitat breadth shapes species' responses to environmental change and influences large‐scale biodiversity patterns. According to Vrba's resource‐use hypothesis, biome specialists (inhabiting a single biome) exhibit higher speciation rates than generalists due to increased population isolation during habitat fragmentation, generally ...

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract Sudden stratospheric warmings (SSWs) can alter the North Atlantic circulation on subseasonal‐to‐seasonal timescales, typically leading to an equatorward shift of the eddy‐driven jet. However, this response is highly variable and can be modulated by other sources of climate variability.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 12, December 2025.ABSTRACT The neotropical otter Lontra longicaudis (Olfers, 1818) is a semi‐aquatic carnivore from the Mustelidae family with a piscivorous habit that interacts with riverine populations because of fishing resources, and this relationship is often negative, especially in the Amazon where fishing represents an important activity for several communities ...
