Obese super athletes: fat-fueled migration in birds and bats
CG Guglielmo - Journal of Experimental Biology, 2018 - journals.biologists.com
Migratory birds are physiologically specialized to accumulate massive fat stores (up to 50–
60% of body mass), and to transport and oxidize fatty acids at very high rates to sustain flight …

Ecology and evolutionary biology of fishing bats
O Aizpurua, A Alberdi - Mammal Review, 2018 - Wiley Online Library
A few of the> 1300 bat species recognised worldwide are known to consume fish to various

Chitinase genes (CHIAs) provide genomic footprints of a post-Cretaceous dietary radiation in placental mammals
The end-Cretaceous extinction led to a massive faunal turnover, with placental mammals
radiating in the wake of nonavian dinosaurs. Fossils indicate that Cretaceous stem …
