Yale Environment 360: “As temperatures rise in northern regions, migrating species are seeing less benefit from migrating north for the summer months, according to scientists who reviewed 25 recent studies. In the warm months, birds, mammals, and insects head north to access food, escape predators, and avoid diseases made worse by summer heat. But with climate change, many species are seeing shrinking food supplies and encountering new parasites and pathogens in the Arctic. This has stunted reproduction and increased mortality among migrating species, the scientists write in the journal Trends in Ecology & Evolution…”
