Unveiling the Evolutionary History of European Vipers and Their Venoms From a Multi‐Omic Approach

open access: yesMolecular Ecology, Volume 34, Issue 21, November 2025.
ABSTRACT Snake genomes attract significant attention from multiple disciplines, including medicine, drug bioprospection, and evolutionary biology. However, genomic research within the Viperidae family has mostly focused on the subfamily Crotalinae, while the true vipers (Viperinae) have largely been overlooked.

ppgm: an R package for integrating neontological, palaeontological, and climate data in a phylogenetic comparative framework

open access: yesPalaeontology, Volume 68, Issue 6, November/December 2025.
Abstract Understanding how changes in climate affect habitat availability for species through time is critical for macroevolutionary, ecological, and conservation research. When combined with palaeoclimate reconstructions, the fossil record provides insights into how species' geographic distributions have responded to past climate shifts, including ...

The Proteome of African Spitting and Non‐Spitting Cobra Venoms and Cytotoxicity Against Pancreatic Cancer Cells

open access: yesJournal of Applied Toxicology, Volume 45, Issue 10, Page 2055-2067, October 2025.
ABSTRACT African cobra (Naja spp.) venom contains toxins dominated by proteins and peptides with inter‐ and intra‐specific variations. There are several FDA‐approved drugs from snake venom toxins from other regions, including South America and Asia. Profiling the proteomes of medically important African cobra venoms from different locations will aid in

A call to integrate non‐visual functions of pigments and their interactions with visual functions to understand global change impacts on visual systems

open access: yesFunctional Ecology, Volume 39, Issue 10, Page 2588-2600, October 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animal coloration serves a variety of visually related functions in nature (e.g. mate choice, aposematism and camouflage) but the pigments in integumentary tissues such as skin, scales and feathers may also serve functions unrelated to the visual environment (e.g ...

Host species and age‐specific variation on Hepatozoon prevalence and its effect on body condition in two Neotropical crocodiles

open access: yesWildlife Biology, Volume 2025, Issue 5, September 2025.
Many populations of species belonging to the order Crocodilia are threatened due to illegal trafficking, indiscriminate hunting, and habitat loss and degradation affecting crocodilian health and parasitic load. Although several studies have revealed that crocodiles, caimans, and alligators are frequently infected by Hepatozoon spp., the results from ...
