Factors associated with the reproductive performance of ewes inseminated laparoscopically in England and Wales: A longitudinal study

Veterinary Record, EarlyView.
Abstract Background Laparoscopic intrauterine artificial insemination (Lap‐AI) is used in sheep genetic improvement programmes. However, the lambing rate (LR) (i.e., the proportion of inseminated ewes that lamb) following Lap‐AI is variable. Previously, one small UK study investigated factors associated with LR, but it did not adjust for dependencies ...

Quantification of steroid hormones in free‐ranging Apennine wolf Canis lupus italicus hair samples collected post‐mortem

Wildlife Biology, EarlyView.
After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.

Tradeoffs between brain and digestive tissues across elevations in Typhlomys daloushanensis: evidence for sexual dimorphism

Wildlife Biology, EarlyView.
To cope with highly stochastic and/or heterogeneous environmental conditions, animals must balance energy resource allocation across physiological processes. The digestive tract and brain exhibit structural variations under strong developmental and selective pressures that vary across environmental gradients both between and within species.

Beyond the enclosure: a decade of monitoring reveals altered traits in a European ground squirrel colony with implications for a recovery program

Wildlife Biology, EarlyView.
Effective integrated conservation programs critically depend on high‐quality animals from ex situ breeding, specifically those that are genetically diverse and physically healthy, yet insufficient scientific rigor in husbandry protocols can lead to unintended, detrimental consequences that compromise reintroduction success.

Demographic buffering in natural populations: A multi‐level perspective

Journal of Animal Ecology, EarlyView.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Advancing fetal autopsy in cases of maceration: Underwater dissection technique and its forensic relevance

Journal of Forensic Sciences, EarlyView.
Abstract Fetal autopsy remains essential for determining the cause of intrauterine death and for supporting clinical, genetic, and forensic evaluations. However, in cases of advanced maceration, autolysis severely compromises tissue integrity, often preventing adequate identification of anatomical structures and limiting the diagnostic and medico‐legal
