Can Herbivore Feeding Preferences Reinforce the Female‐Biased Sex Ratio in an Alpine Willow?

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Sex‐biased herbivory can vary among co‐occurring herbivores and across the season. Sequential herbivory by species with different feeding preferences may influence the population dynamics of dioecious plants, particularly if early‐season herbivory alters plant traits that affect subsequent foraging decisions.

A Worldwide Review of Snowy Owl Feeding Ecology: The Importance of Lemmings and Voles in a Changing Climate

Birds
We compared Snowy Owl feeding ecology from 15 breeding season studies throughout Nearctic and Palearctic circumpolar regions. We used raw data and information theory to assess the owls’ feeding niche.

Whole System Ecohydrological Change Following Natural Flood Management and a Five‐Year Beaver Reintroduction Trial

Ecohydrology, Volume 19, Issue 4, June 2026.
ABSTRACT Once‐common beavers have been absent from the British landscape for centuries, but wild beaver populations have returned in recent years as part of reintroduction schemes, including releases into monitored enclosures. In North Yorkshire, such a release of Eurasian beavers took place in 2019.

Habitat and Body Condition of Small Mammals in a Country at Mid-Latitude

Land
The relationship between the body condition of different small mammal species and the habitat they occupy is poorly analyzed. We analyzed the body condition index, BCI, of 18 small mammal species trapped in forest, shrub, wetland, meadow, riparian, mixed

Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra

Ecography, Volume 2026, Issue 6, June 2026.
Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.

Extreme Body Condition Index Values in Small Mammals

Life
The body condition index (BCI) values in small mammals are important in understanding their survival and reproduction. The upper values could be related to the Chitty effect (presence of very heavy individuals), while the minimum ones are little known ...

Individual characteristics, experience, and environmental conditions shape large‐scale patterns of animal activity timing

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract The timing of an animal's activity affects its survival and reproduction because timing determines the nature of every interaction an organism has with its environment. Although the timing of activity may depend on aspects of the individual (e.g., body mass, reproductive status, experience) or the nature of the environment (e.g., temperature ...

Effects of Fluorescence‐Activated Cell Sorting on Boar Sperm Motility Subpopulations and In Vitro Embryo Development

Molecular Reproduction and Development, Volume 93, Issue 6, June 2026.
Effects of fluorescence‐activated sperm sorting on IVF outcomes and motility subpopulations. Distinct boar ejaculates were either used directly for in vitro fertilization (IVF; control, unsorted) or processed by fluorescence‐activated cell sorting to generate a sorted sperm population.

Shedding light on the dark: Does artificial illumination affect mammal activity at waterholes in sub‐Saharan Africa?

Conservation Science and Practice, Volume 8, Issue 6, June 2026.
We experimentally evaluated the effects of artificial lighting on mammal visitation patterns at waterholes in north‐central Namibia using motion‐activated camera traps across two dry seasons. Lighting had minimal effects on most species, although gemsboks increased use of artificially lit waterholes and lions reduced nocturnal activity at illuminated ...

Nonapeptide molecular evolution during the adaptive radiation of Tanganyika cichlids

Journal of Neuroendocrinology, Volume 38, Issue 6, June 2026.
Abstract Oxytocin (OT) and vasotocin (VT) are evolutionarily conserved nonapeptides that regulate a wide range of physiological and behavioral processes in vertebrates. Their receptor families have undergone gene duplications that facilitated functional diversification throughout vertebrate evolution.
