Heat Changes Insect Call, but It Still Works


Sounds they produce. We can't hear take tiny insects called tree hoppers. They communicate through vibrations when a male tree hopper is hunting for a mate mate. He vibrates his body to produce a special love song. They sound like Ooh Book Casey Fowler. Finn is an assistant professor of biology at Saint Louis University University. She says if a female tree hopper is interested. She'll vibrate back to the Mayo basically her way of saying hey there fowler fin wondered if tree hopper mating songs might change at different temperatures which could affect whether the species survives as the climate changes so she and Grad student Dillwyn Hawks in built custom custom incubators using plywood and Kia shelves plus a special leaser that helps them listen to tree hoppers. The laser receives information about these tiny vibrations actions on the plant stem which we then amplify and process into sounds that we can hear turns out the tree huggers do sound different when the temperature changes. Here's a male singing at sixty five degrees and another at ninety seven degrees but that's not all the team recorded these songs and played them for females to see if they still find them attractive so essentially we're having a conversation with the insect because we can play back a bunch of different signals to females and ask her how much she likes. Each one as male tree hopper love songs changed across temperatures females still recognize ignites them saying Yep. I'm interested in meeting with you hawks and says that was exciting. I think when we saw that we were just like wow this is awesome. The study appeared appeared in the Journal of evolutionary biology. She says this is just one piece of the puzzle but it gives her some hope that tree hoppers and other similar insect species will keep things steamy even as the climate warms for scientific
