Communicating change in a ‘land of extremes’ In Aurora MacRae-Crerar’s Penn Global Seminar, students are grappling with the impacts of a shifting and unpredictable climate in Mongolia. Yurts, known as gers in Mongolia, were the dwelling of choice during Aurora MacCrae-Crerar s biology doctoral studies there. Now an instructor in the Critical Writing Program, MacRae-Crerar was inspired to craft a Penn Global Seminar focused on how climate change is affecting the country. (Image: Peter Petraitis)

Two new species of endangered screech owls identified from Brazil
by Liz Kimbrough on 1 April 2021
Two new species of tiny screech owls from the Amazon and Atlantic rainforests in Brazil have been described by science.
Prior to the discovery, the new owl species were grouped together with two other South American species, but by closely examining their calls, DNA, and appearance, scientists determined that there were enough differences to classify two new species.
Although the owls are new to science, they are at risk of extinction, and will likely be classified as critically endangered.
