Experimentally Testing the Hypothesis That Hybrid Fitness Can Increase Evolutionarily: An Example in Spadefoot Toads

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Low hybrid fitness is often generated by “genetic incompatibilities” that arise between the parental species' genomes. Our study provides experimental evidence that selection against such incompatibilities might result in the evolutionary increase of hybrid fitness over time.

Hormone Profiles After Planned Low Energy Availability Exposure in Naturally Menstruating and Hormonal Contraceptive Using Physique Athletes

European Journal of Sport Science, Volume 25, Issue 12, December 2025.
ABSTRACT This observational study investigated the potential influence of hormonal contraceptive (HC) use on selected hormonal biomarkers (estradiol, total testosterone, IGF‐1, cortisol, triiodothyronine, and leptin) that respond to diet and physical training–induced low energy availability (LEA).

The Transgenerational Link: Breeder Gut Microbiota and Broiler Progeny Development

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
The breeder hen gut microbiome, shaped by maternal factors and targeted nutrition, drives reproductive performance and transmits beneficial microbes that programme gut health, immunity, and growth in progeny. Microbiome‐focused interventions can optimise egg quality, hatchability, progeny performance, and sustainability in poultry production.

Ovarian Aging: Mechanisms, Age‐Related Disorders, and Therapeutic Interventions

MedComm, Volume 6, Issue 12, December 2025.
A comprehensive overview of the molecular mechanisms underlying ovarian aging, its association with age‐related diseases, and potential therapeutic interventions. Ovarian aging involves DNA damage, mitochondrial dysfunction, oxidative stress, telomere attrition, and follicular depletion, driving age‐related infertility, menopause, and multiple systemic
