Scientists solve Killer Whales menopause mystery

Scientists solve killer whales’ menopause mystery

Benefits of grandmothering may have played a major role in the success of older female orcas (killer whales) but the costs of being outcompeted by their daughters apparently play a role in the emergence of their menopause, a new study suggested.

According to the study, published in the journal Current Biology, younger females are more likely to mate and reproduce than their older counterparts. They found that this trend puts off mother orcas from reproduction, which in turn make them more focused on raising their younger members of their families instead.

Cheetahs Face Extinction Risk as Number in the Wild drops to 7,100

Cheetahs Face Extinction Risk as Number in the Wild drops to 7,100

Cheetahs in the wild have declined and conservationists have alarmed authorities about the risk of extinction the species faces. The results of a major worldwide survey released last week has suggested that the number of cheetahs in the wild could be around 7,100. At the start of last century, the number of cheetahs in the wild was over 100,000. The loss of population has mainly happened due to loss of natural habitat for cheetahs. The fastest animal on the earth is sprinting towards extinction, the research team involved with the counting of cheetahs informed.

Bats Communicate in Different Ways and Vocalize a lot during Information Exchange: Research

Bats communicate and share information in more ways than earlier known to scientists, as per a new research conducted at the Bat Lab for Neuro-Ecology at Tel Aviv University. During their analysis of bat squeaking, the research team found different tones for calls related to food, sleep or mating. The research team said that they still need to decipher many of the signals but they are sure that there are lot of different signals that bats use for communication.

Conservationists want cheetahs to be defined as “endangered” species

The fastest running animal on land is facing high risk of extinction as the number in the wild has reduced to nearly 7,100. There were more than 100,000 cheetahs in Africa in the start of last century. The research paper published in the Proceedings of the National Academy of Sciences has urged for status of cheetah to be converted to 'endangered'. Amid persistently shrinking populations of cheetah across Africa and other historic habitats around the world, conservationists have sounded alarm bells for the fastest animal on land.
