Condition‐Dependent Responses to Risk in a Small Mammal

open access: yesEthology, Volume 132, Issue 1, Page 55-66, January 2026.
Responses to a predation risk gradient vary as a function of the resource environment and individual condition in a small mammal. ABSTRACT Animal responses to risky situations are shaped by both environmental (external) cues and internal states such as body condition.

Mystery of the Disappearing Dogfish: Transboundary Analyses Reveal Steep Population Declines Across the Northeast Pacific With Little Evidence for Regional Redistribution

open access: yesFish and Fisheries, Volume 27, Issue 1, Page 1-12, January 2026.
ABSTRACT Quantifying broad‐scale population trends and distribution change is critical for effective management and conservation of marine species, particularly under climate change. However, fragmented regional survey data often hinder such efforts for transboundary populations. A prime example is Pacific Spiny Dogfish (Squalus suckleyi, Squalidae), a

Breeding habitat preferences and niche partitioning of insectivorous songbirds in Alpine grasslands

open access: yesIbis, Volume 168, Issue 1, Page 329-344, January 2026.
Alpine grasslands are increasingly facing pressures of climate and land‐use changes. Higher temperatures and pastoral abandonment lead to treeline shift and to bush encroachment, while agricultural intensification causes soil eutrophication and landscape homogenization. Alpine grasslands in Europe host important populations of mountain specialists that

Chromosomal Diversity as a Predictor of Lineage Diversification in Ants Across Phylogenetic and Geographic Gradients

open access: yesJournal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim To investigate macroevolutionary and biogeographic patterns of chromosome number variation in ants (Formicidae), and to test whether chromosomal diversity is taxonomically structured, associated with species richness, varies with latitude, and accumulates over evolutionary time. Location Global.

Repeated Independent Formation of Triploid Lineages Contributes to Clonal Diversity in Heteronotia binoei Parthenogens

open access: yesMolecular Ecology, Volume 35, Issue 2, January 2026.
ABSTRACT Parthenogenesis, or all‐female clonal reproduction, is rare among vertebrates. This is often attributed to the selective disadvantages of assumed reduction of genetic diversity in the absence of sex. However, parthenogenetic vertebrates have highly complex evolutionary histories, with most arising through hybridisation and many being polyploid.
