Wild animals provide a unique challenge for physiologists because they are difficult to capture and monitor in their natural habitats. As a result, scientists are increasingly learning about organisms ...

A mega-study of 117 mammal species reveals that limiting reproduction increases life expectancy by up to 10 percent.

Microglia (immune cells) and the RANK protein are essential for triggering puberty and maintaining fertility in the brain.

The University of Ottawa's Department of Biology made a significant contribution to the comprehensive 2024 Amphibian Conservation Action Plan (ACAP). Professor Vance L. Trudeau's work is featured in ...

I probably don't need to tell you that, although they're among our most basic biological functions as human beings, conception and pregnancy are basically the closest any of us are ever going to get ...

The adoption of individual-cow monitoring technology has created the ability to customize reproductive decisions based on the potential of each cow to respond to a specific breeding strategy.

Animal reproduction science focuses on dogs, pigs, ruminants and horses. Research on ruminant reproduction (female reproduction) has focused on three research lines: The use of the GnRH hormone for ...

Here are 10 animals that have some of the highest levels of testosterone and the impact it has on their behavior and characteristics.
