The Appalachia + Mid-South Newsroom presents: Signal Species
A “signal” or “indicator” species is an organism that can tell us about changes occurring in an ecosystem.
We’re talking bears encountering humans more frequently, armadillos moving farther north, invasive vines like kudzu growing at accelerated rates and bat populations dwindling.
These are all examples of species sending us signals about our changing world and climate — but are we paying attention? And if we are, is there a way to contribute to scientific findings? (Spoiler alert: Yes! iNaturalist will be entering the chat.)
The Appalachia + Mid-South Newsroom and our partner stations in Tennessee, Kentucky and West Virginia are bringing you answers through a series of features all about wildlife. We'll publish a new story each Monday in June, with full episodes of WPLN's This Is Nashville dedicated to the series airing on June 2 and June 23.
