Scientists studied water fleas to reveal how natural selection subtly operates in stable environments, offering insights into ...

The study of genetic variation and growth traits in tree species is crucial for understanding the mechanisms that underpin forest productivity, resilience and adaptation. Recent advances in molecular ...

One of the curious things in the world of birds is why most species come in only one color form, while others come in many. We can start with the western tanager. Adult males all look the same. Adult ...
