What do We Mean by Environmental Heterogeneity? Toward A Mechanistically Explicit and Scale‐Dependent Framework

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
We synthesized 360 studies on environmental heterogeneity (EH) across taxa, regions, and disciplines. Only 10% of studies explicitly defined EH, and definitions were predominantly descriptive. We identify four operational interpretations of EH and propose a Research Roadmap linking EH metrics to five mechanistic hypotheses with testable predictions ...

Sexual Dimorphism as a Potential Driver of Trophic Specialisation in a Sedentary Synanthropic Bat Species

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Female common serotine bats (Cnephaeus serotinus) are consistently larger than males in forearm length, wing area and mandibular dimensions related to bite force. Wing dimorphism reflects isometric size scaling rather than shape divergence, suggesting compensation for pregnancy‐related mass increases.

Epigenetic and Brain Structure Covariation Patterns in Typical and Atypical Development

open access: yesHuman Brain Mapping, Volume 47, Issue 11, 01 August 2026.
We present a map linking DNA methylation to brain structure in childhood. Genes in which methylation was linked to brain anatomy are highly enriched for those implicated in psychiatric and neurodevelopmental disorders, highlighting potential epigenetic targets for understanding both typical and atypical brain development.

Role of ClpX and MsrA/B in the Oxidative and Cell Wall Stress Response in Bacillus anthracis Sterne

open access: yesMicrobiologyOpen, Volume 15, Issue 4, August 2026.
Methionine sulfoxide reductase (msrA/B) is an oxidative response enzyme that reduces oxidized methionine residues to maintain protein function. Surprisingly, loss of MsrA/B does not increase sensitivity to hydrogen peroxide or paraquat‐induced oxidative stress in Bacillus anthracis Sterne.
