Unlocking the Secrets of Female Common Dolphin Reproduction in New Zealand

Understanding the life history of organisms helps us learn how they grow and develop traits that help them survive in their environment. It also reveals how vulnerable a population can be if certain behaviors and traits put them at risk of extinction. In our rapidly changing world, studying a species’ life history is important to […]

Scientists can now use the DNA of dolphins to know their age

One of the most fundamental pieces of information about individuals (including dolphins) is their age. In biology studies, scientists need to know how old an animal is to understand many aspects of its life history and, for example, to estimate the viability of a population. But estimating an animal’s age is no easy feat when
