Quaternary Climatic Changes and Biogeographic Barriers Drove Codiversification in the Obligate Mutualism Between Camponotus laevigatus and Its Endosymbiont Blochmanniella

Ecology and Evolution, Volume 16, Issue 7, July 2026.
In this study, we examined the codiversification and phylogeography of Camponotus laevigatus and its obligate endosymbiont Blochmanniella using a population genomic approach. Using whole‐genome sequencing, we identified three phylogeographic clusters with congruent host‐endosymbiont phylogenies, significant isolation‐by‐distance, and Pleistocene ...

Bioinformatics‐Driven Design and Evaluation of Recombinant Multi‐Epitope Immunogens Derived From Snake Venom Toxins as Potential Antivenom Candidates

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 7, Page 1403-1426, July 2026.
ABSTRACT Snakebite envenomation is a major public health concern, particularly in low‐ and middle‐income regions where access to safe and effective antivenoms is limited. Traditional antivenoms, derived from immunization with crude venom, often trigger adverse reactions and lack specificity against key venom components.

Assessing the Evolutionary Potential of Endangered Populations Using Genomic Analyses of Selection in Ecologically Important Gene Regions

Molecular Ecology, Volume 35, Issue 14, July 2026.
ABSTRACT Evolutionary potential, the capacity to evolve in response to environmental change, is important for the persistence of threatened species. This potential is diminished by genetic drift in small populations, causing the loss of genetic diversity and reduced efficiency of selection.

When the Cover Burns: Behavioral and Morphological Responses of Western Fence Lizards (Sceloporus occidentalis) to Increased Openness in Post‐Fire Environments

Ecology and Evolution, Volume 16, Issue 6, June 2026.
We found that Western Fence Lizards experience higher detectability in burned areas but do not consistently darken or adjust perch use to enhance background matching, despite showing improved camouflage on darker substrates. These results suggest that lizards may face behavioral trade‐offs in post‐fire landscapes that could influence success.

Generalist With a Narrow Niche Breadth: Feeding Ecology and Seed Germination Effectiveness of a Large Canid Within a Silvicultural Matrix

Austral Ecology, Volume 51, Issue 6, June 2026.
Diet: The generalist canid exhibits a narrow niche breadth (0.12), consuming native plants (100% frequency) and animals (85%). Birds dominate animal prey (74%), peaking in the dry season, while Solanaceae plants dominate plant food (100%), peaking in the rainy season.
