Record phenological responses to climate change in three sympatric penguin species

Journal of Animal Ecology, Volume 95, Issue 3, Page 455-469, March 2026.
This paper is impressive because we managed to monitor extensively a really difficult place to reach and operate in. We deployed 77 cameras across Antarctica and the Sub Antarctic islands to monitor three different species of penguins. We found that they are the fastest advancing vertebrates with respect to their timing of breeding.

Animal–Plant Interactions Under Defaunation: Consequences for Amazonian Trees of Commercial Interest

Biotropica, Volume 58, Issue 2, March 2026.
We experimentally investigated the effects of medium‐ and large‐sized mammal defaunation on the removal and fate of seeds from economically important forest species in Amazonian forests. Our results show that mammal exclusion significantly reduced seed removal, although the magnitude of this effect varied among plant species.

Mechanism of ITGB2 in Osteoclast Differentiation in Osteoarthritis

Cell Proliferation, Volume 59, Issue 3, March 2026.
In osteoclast precursors, higher ITGB1 than ITGB2 expression increases ITGA2‐ITGB1 integrin. In OA, extracellular signals upregulate ITGB2 and downregulate ITGB1, enhancing ITGA2‐ITGB2 integrin. This activates Rac1 to Rac‐GTP, driving osteoclast differentiation. Hyperactive subchondral osteoclasts accelerate OA progression.

Fine‐Scale Genomic Divergence in the Amazonian Pirarucu (Arapaima gigas) Highlights the Need for Local Management Strategies

Freshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Freshwater habitats face significant human disturbances globally, impacting food security and ecosystems. Protected areas can mitigate biodiversity loss, but limited data on population connectivity hinders conservation management. This study examines pirarucu (Arapaima gigas), a heavily exploited and threatened Amazonian fish, using genomic ...
