The State of Nature Update #29

In this edition of Nature Signals, we explore some of the latest stories shaping our understanding of biodiversity, wildlife and conservation around the world.

The episode begins with the wandering glider dragonfly, also known as the globe skimmer, which can cross oceans and travel up to 18,000 kilometers (11,000 miles) across multiple generations—making it the longest-known insect migration. We then examine how climate change is fueling bigger and hotter wildfires across the western United States, transforming local forests. But intentionally set prescribed burns may help protect fire-adapted ecosystems and giant sequoias, counteracting some of the devastating effects of warming temperatures.

The episode also looks at how animals are evolving in response to human environments, from changes in urban birds and lizards to declining aggression in raccoons. Another story considers whether animal cultures and learned behaviors should play a greater role in wildlife conservation and Endangered Species Act decisions.

Finally, we report on an ambitious bird flu vaccination program for little penguins in Australia, highlighting the growing conservation challenges facing wildlife.
