Invasive grasses get help from fire, and a global map of ant diversity

Invasive grasses get help from fire, and a global map of ant diversity

On this week’s show: A special issue on grass, and revealing hot spots of ant diversity This week’s special issue on grasses mainly focuses on the importance of these plants in climate change, in ecosystems, on land, and in the water. But for the podcast, Contributing Correspondent Warren Cornwall joins host Sarah Crespi to talk about their dark side: invasive grasses that feed fires and transform ecosystems. Also this week on the show, Evan Economo, a professor in the biodiversity and biocomplexity unit at the Okinawa Institute of Science and Technology, joins Sarah to discuss his Science Advances paper on creating a worldwide map of ant diversity. Such maps help us better understand where vertebrate and invertebrate diversity do and don’t overlap and what this means for conservation. If you want to explore the data, you can see them at antmaps.org. This week’s episode was produced with help from Podigy.
