- Title
Evolutionary biology: Sperm signals.
- Abstract
The article reports on a study conducted by Fabrice Helfenstein and his team at the University of Bern in Switzerland which confirms that male birds that are more colorful can better protect their sperm from oxidative stress. It states that the researchers followed a breeding population of great tits (Parus major), and strengthened the workload of the bird by making two nestlings to each brood. The result shows that sperm motility decreased and their is more lipid damage in less colorful males.
