A study looked at heat stress in bumblebees and how that might affect their nests. Warming temperatures could be responsible for a worldwide bumblebee decline, a new analysis finds and the damage may rise as temperatures soar because of climate change. Published in Frontiers in Bee Science, the study looked at heat stress in bumblebees, reviewing 180 years worth of literature to determine the optimal temperature of bumblebees brood nests. The hundreds of species of bumblebee function best when their brood nest remains between 82.4 and 89.6 Fahrenheit, scientists conclude a range that, though narrow, has remarkable uniformity.
