However, bats are the exception to the rule, displaying small body sizes in both hot and cold regions. A ƽÌØÎå²»ÖÐ-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.</p> Thu, 21 Jul 2022 16:33:35 +0000 frederique.mazerolle@mcgill.ca 288261 at /newsroom /newsroom/channels/news/puffins-stay-cool-thanks-their-large-beak-302883 <p>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.</p> <p>In a new <a href="https://jeb.biologists.org/content/222/21/jeb212563.full">study</a> published in the <em>Journal of </em><i>Experimental Biology</i>, researchers from ƽÌØÎå²»ÖÐ 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.</p> Tue, 26 Nov 2019 21:18:23 +0000 justin.dupuis@mcgill.ca 189310 at /newsroom
