Many mammal species living in cold climates tend to have large bodies and short limbs to reduce heat loss – a general pattern known as Bergmann’s rule. However, bats are the exception to the rule, displaying small body sizes in both hot and cold regions. A McGill-led team of researchers is shedding light on this long-standing debate over bats’ body sizes and focus on why bats are seemingly non-conforming to ecogeographical patterns found in other mammals. Their findings offer a new method for investigating complex macroecology across bat species.

Tufted puffins regulate their body temperature thanks to their large bills, an evolutionary trait that might explain their capacity to fly for long periods in search for food.
In a new published in the Journal of Experimental Biology, researchers from Ï㽶ÊÓƵ and the University of California, Davis, used thermal imaging cameras to measure heat dissipation off the bodies and beaks of wild tufted puffins in the minutes after flying.
