Boom‐Bust Dynamics Drive Community‐Wide Dietary Structuring in Desert‐Dwelling Raptors

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We investigated how boom‐bust productivity dynamics affected dietary structuring within raptor communities of an arid bioregion. We found that higher productivity was associated with high dietary overlap, lower niche breadth and greater foraging on small mammals; however, raptors that were nomadic exhibited greater specialisation regardless of ...

The many dimeric faces of Lys49 PLA2‐like proteins: Conformational plasticity and membrane binding drive functional dimer states

open access: yesProtein Science, Volume 35, Issue 2, February 2026.
Abstract Lys49 secreted phospholipase A2‐like proteins (sPLA2s) are major myotoxins in viperid snake venoms, causing rapid muscle damage in envenomation. Beyond their clinical relevance, these small non‐catalytic proteins provide a model to study how quaternary structure and conformational dynamics enable catalysis‐independent membrane disruption ...

Advances in Bioinspired Interfacial Adhesion with Frictional Enhancement: From Fundamental Research to Biomimetic Applications

open access: yesSmall Structures, Volume 7, Issue 2, February 2026.
Biological models in nature reveal remarkable friction‐adhesion mechanisms, driven by intermolecular forces and suction. Researchers leverage these principles to design advanced materials with enhanced adhesion properties. By optimizing these materials under stimuli like light and electricity, new solutions emerge for regulating interface interactions ...

The Importance of Environmental Heterogeneity in Evaluating the Conservation Status of Two Frog Species in a Changing Amazonian Interfluve

open access: yesAnimal Conservation, Volume 29, Issue 1, Page 60-70, February 2026.
Identifying the most effective criterion to assess the conservation status of vulnerable species in threatened tropical regions is crucial to evaluate recovery plans. We investigated the influence of environmental heterogeneity on the extent of occurrence (EOO), area of occupied habitat (AOH), and density variation of two Amazonian riparian frog ...

Models of cardiomyocyte–non‐myocyte electrical interactions

open access: yesThe Journal of Physiology, Volume 604, Issue 4, Page 1607-1628, 15 February 2026.
Abstract figure legend Cardiomyocyte–non‐myocyte (CM–NM) electrotonic coupling. Left: conceptual contact‐based interactions between CM and other NM via connexin (Cx) proteins. Three basic scenarios are proposed: (i) ‘zero‐sided coupling’ where there are no electrical connections between CM and NM, (ii) ‘single‐sided coupling’ where NM are connected to ...

Structural characterization, antioxidant and antitumor properties of an acidic polysaccharide from toad venom

open access: yesChemical and Biological Technologies in Agriculture
Background As a valuable agricultural product derived primarily from cultivated toads, toad venom has been widely used for its significant antitumor properties in pharmacological formulations. However, the structural and biological characteristics of its
