Whipped and Mixed Warm Clouds in the Deep Sea

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Turbulence is indispensable to redistribute nutrients for all life forms larger than microbial, on land and in the ocean. Yet, the development of deep‐sea turbulence was not studied in three dimensions to date. As a disproportionate laboratory, an array of nearly 3,000 high‐resolution temperature sensors had been installed for three years on ...

Smart Ungulates: What Sheep and Goats' Performances in a Reversed‐Reward Contingency Task Tell Us About the Evolution of Cognitive Flexibility

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
This study shows that young goats outperform sheep in the reversed‐reward contingency task, which is a cognitive test requiring both inhibitory control and cognitive flexibility. The results highlight the importance of cognitive flexibility when solving this type of task, and suggest that the differences between both species may reflect social and ...

Comprehensive Analysis of PAPPA2 Expression and Genetic Variants in Sheep and Their Association With Litter Size

open access: yesVeterinary Medicine and Science, Volume 12, Issue 1, January 2026.
ABSTRACT Background The PAPPA2 gene encodes a metalloproteinase critical for regulating insulin‐like growth factor (IGF) bioavailability through cleavage of insulin‐like growth factor‐binding protein 5 (IGFBP5). While its role in human and murine reproduction is documented, its function in sheep reproductive traits remains underexplored. Objective This

Preattentive texture discrimination with early vision mechanisms [PDF]

open access: yes, 1990
We present a model of human preattentive texture perception. This model consists of three stages: (1) convolution of the image with a bank of even-symmetric linear filters followed by half-wave rectification to give a set of responses modeling outputs of

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

open access: yesJournal 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.

At‐sea distribution of seals on the Northwest European Shelf: Towards transboundary conservation and management

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
This study provides the first comprehensive, regionally scalable distribution estimates for pinnipeds across the NWES and its constituent countries. The modelling framework is adaptable to other central‐place and migratory species, supporting transboundary biodiversity assessments and international conservation policy. We discuss common limitations and
