Energy intake is a critical determinant of reproductive performance in small mammals, particularly during energetically demanding periods such as lactation. Recent investigations have revealed that ...

A new article in Ecological and Evolutionary Physiology examines how the immune system and reproduction interact in female mammals, especially during pregnancy, from mating to birth. Lauren E.

The new embryo enters embryonic diapause until the new-born offspring leaves the pouch nine months later. Thus, when the embryonic diapause is included, females are continuously pregnant throughout ...

xplores the various methods of animal reproduction, highlighting the dependency of young animals on their parents, particularly in mammals, birds, and amphibians. It explains both asexual reproduction ...

With a remaining population of two females worldwide, the Northern White Rhinoceros is acutely threatened with extinction. A research team wants to prevent the worlds’ rarest large living mammal from ...

The kisspeptin system is increasingly recognised as a central regulator of reproductive physiology in fish. Unlike mammals, teleosts often harbour two or more kisspeptin genes (e.g. Kiss1 and Kiss2) ...
