'Mayor Pete' and the Climate / Beyond the Headlines / Fearsome Bull Elephant Musth / Science Note: Can Plants Hear? / Pesticide Risks Ignored at Trump Interior Dept. / BirdNote®: Sage Grouse Lek and Grasslands / The Sage Hen and the Sage Brush / Greater Peril for the Greater Sage Grouse Pete Buttigieg, the 37-year-old mayor of South Bend, Indiana, is making climate change a focal point of his forward-looking campaign.
