Microbial Contributions to Primate Reproduction

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 1, March 2026.
ABSTRACT Reproduction is a complex process, and microbes play a far greater role than previously imagined. This review explores the ways that microbiomes influence the rich tapestry of reproductive processes and outcomes within the primate lineage, including pre‐copulatory and post‐copulatory mechanisms.

Effects of 17α‐Ethinylestradiol on Development and Gonadal Differentiation in the Estuarine Mummichog, Fundulus heteroclitus

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 2, Page 148-161, March 2026.
ABSTRACT In fish, sex determination and gonadal development are controlled by various genetic and environmental factors. In this study, experiments were conducted on the estuarine mummichog (Fundulus heteroclitus) to investigate gonadal differentiation following exposure to the synthetic estrogen, 17α‐ethinylestradiol (EE2).

Chromatin Accessibility in Cancer: Biological Functions, Mechanisms, Therapeutic Potential, and Future Directions

MedComm, Volume 7, Issue 3, March 2026.
Cancer remains the leading cause of mortality worldwide, and drug resistance further underscores the urgent need for innovative therapeutic strategies. Chromatin, a stable yet highly dynamic nucleoprotein complex, serves as the primary carrier of genetic material in eukaryotic cells.

Seasonal body mass dynamics mediate life‐history trade‐offs in a hibernating mammal

Journal of Animal Ecology, Volume 95, Issue 3, Page 383-396, March 2026.
We tested a suite of ecological hypotheses to explain variation in seasonal body mass dynamics of a fat‐storing mammalian hibernator. We further demonstrated that pre‐hibernation mass gain in ground squirrels mediates an annual allocation trade‐off between current and future reproduction as the squirrels forage and rear young under predation risk ...

Immunostaining of P450c17, Aromatase and Oestrogen Receptor Alpha in Germ and Somatic Cells During Gonadal Development in Greater Rhea

Anatomia, Histologia, Embryologia, Volume 55, Issue 2, March 2026.
ABSTRACT The greater rhea (Rhea americana), the largest bird species in South America, has significant economic value due to its meat, eggs, leather, feathers and oil. However, its lack of external sexual dimorphism poses challenges for reproductive management and breeding programmes.
