Telomere Length Is Determined by Intrinsic Factors and Is Shortened During Drought Years in Gallotia galloti

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Telomere dynamics in ectotherms remain poorly understood relative to endotherms, yet are increasingly relevant in the context of climate change. Here, we used model‐averaged GLMMs and hierarchical partitioning to disentangle intrinsic and extrinsic drivers of relative telomere length in the Western‐Canaries Lizard (Gallotia galloti) across a 10‐year ...

Social Organisation Predicts Lifespan in Mammals

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Using Bayesian phylogenetic analyses of 1436 mammal species, we show that pair‐living and group‐living species have longer maximum lifespans than solitary species after accounting for body mass and phylogeny. Differences between pair‐ and group‐living species were small, and activity period showed weak associations.

Body Size Trade‐Offs Underpin Reproductive Success and Thermal Stress Tolerance in an Invasive Pest, the Small Hive Beetle

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Body size differences have widely been observed in adult small hive beetles (Aethina tumida Murray, SHBs), an invasive pest of honey bee colonies. We hypothesized that parental body size influences reproductive performance, progeny fitness, and stress tolerance in SHBs.

Transcriptomic and DNA Methylation Profiles of Alternative Aphid Morphs and Genotypes

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Graph showing the correlation between differentially expressed genes and differentially methylated genes. There is no correlation between gene expression and DNA methylation level in pea aphid polyphenism. ABSTRACT Pea aphids can develop alternative morphs when exposed to stressful conditions, showing differences between genotypes in their stress ...

Contrasted habitat selection among Eurasian curlew populations according to landscape heterogeneity and breeding stage

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
This study aimed to quantify the spatio‐temporal use of breeding environments by the Eurasian curlew in 5 contrasting agricultural landscapes. To this end, 64 individuals were tagged with GPS devices to assess their space use according to their breeding stages and define their foraging habitat selection.

Morphometric Analysis of the Pituitary Gland and Sella Turcica Using Computed Tomography Images in Hamdani Sheep: Evaluation of Sexual Dimorphism

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
In this study, computed tomography was employed to assess the morphometry of the pituitary gland and sella turcica in Hamdani sheep. Analysis demonstrated distinct sexual dimorphism, with males exhibiting significantly higher values across all volumetric and osteometric parameters.

Seroprevalence and Risk Analysis of Toxoplasma Gondii in Wild Birds of District Lahore Punjab, Pakistan

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
This study found that over 10% of wild birds in Lahore, Pakistan, carry antibodies for Toxoplasma gondii, a parasite that can cause serious illness in humans and animals. Birds like lapwings and silver bills showed especially high antibody rates. Improved monitoring is needed to better understand risk dynamics in Pakistan.

The Red Queen unveils the sexual and mating strategies of flowers

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.
