Recently, marine researchers have developed a new technique of baleen research in which they are able to take baleen from dead whales in order to look back in time at the whale’s history. Scientists are able to use chemical analysis in order to learn about a whale’s hormone levels, reproduction rates, and eating habits within the last decade. By studying the stress levels of the whale, researchers can determine what is causing the whale stress, such as fishing nets or lack of food, and use that information to repopulate the dying species. Similarly, scientists can use the baleen from the dead whales to test for pregnancies to predict why there has been a decrease in whale calves. The marine researchers hope to be able to use the method of testing to look even farther back in time and see the changes in the whale species from decades ago.
I think the new practice of baleen research is extremely beneficial to the whale species because it can help researchers pin point exactly what is causing the decline of whale population and get to the root of the problem immediately. The article however did not address what further precautions the researchers plan on taking and what further actions they can do to prevent the endangered species from becoming extinct. The article exemplifies how with growing technologies scientists are able to understand certain species better and use it to prevent future deaths from these animals.
