Climate and weather Biodiversity Technology for environmental change Natural disasters Anthropogenic disasters Public outreach Enviornmental policy Environmental news and activism.

This assignment is designed to have you explore environmental science and biology in the news. This is a recurring weekly assignment that will require you to look up different articles each week Please go online and search for a recent scientific article on any subject within environmental science. These can be articles about recent discoveries, current research or environmental concerns (just to name a few) Subjects include but are not limited to: Climate and weather Biodiversity Technology for environmental change Natural disasters Anthropogenic disasters Public outreach Enviornmental policy Environmental news and activism These articles must have been published within six months or so (nothing older than December 2019). These articles must also be from reputable scientific news outlets such as scientific magazines or online scientific news sites. Reputable scientific magazines include: Science News Scientific American National Geographic Time Reputable online scientific news sites include: Science Daily (?? ???? ?????.) IFL Science – Environment (?? ???? ?????.) VICE News – Environment (?? ???? ?????.) Please note that this example is about historic climate change and paleontology. An article about paleontology would not recieve full credit on your assignment Title: Woolly Rhinos Died Out Due To Climate Change, Not Overhunting Online Source: IFL Science https://www.iflscience.com/plants-and-animals/woolly-rhinos-died-out-due-to-climate-change-not-overhunting/ (?? ???? ?????.) Peer-reviewed journal: Current Biology; Pre-extinction Demographic Stability and Genomic Signatures of Adaptation in the Woolly Rhinoceros New research indicates that the woolly rhinoceros went extinct as a result of climate change, specifically a burst of temperature increase towards the end of the last Ice Age. Researchers used genomic evidence complied from samples of tissue from 14 wooly rhinoceroses to examine the population size and genetic diversity found within Siberia. Based on the genomic evidence, it seems that woolly rhinoceros populations were fairly stable long after the first appearance of humans in Siberia. This discovery directly counters the idea that the species went extinct due to direct human impact in the form of hunting and overharvest. According to researcher Love Dalen, there may have actually been a bit of a population increase during the first appearance of humans in Siberia. The genomic samples also show evidence that certain mutations were present that helped the rhinoceroses adapt to climate changes, although it might have ultimately been some of these mutations that lead to the species extinction during the Bølling-Allerød interstadial period. Researchers say the next step to untangling the cause of the woolly rhinoceros extinction is to get more genomic samples from individuals between 18,000 and 14,000 years old, which would put them very close to the date of extinction. Using samples that are this old could indicate the point of population decline and may give further insight to the study. This study is significant in that it sheds light on the cause of prehistoric megafaunal declines that are non-anthropogenic in nature. It also provides evidence for genetic adaptation of cold-climate species to climate change and warming, which could provide numerous implications for the current environmental crises and a broad picture of overall adaptability.
