Fruit, nectar, bugs and blood: How bat teeth and jaws evolved for a diverse dinnertime
There are more than 200 species of noctilionoid bats, mostly in the American tropics. And despite being close relatives, their jaws evolved in wildly divergent shapes and sizes to exploit different food sources. A paper published Aug. 22 in Nature Communications shows those adaptations include dramatic, but also consistent, modifications to tooth number, size, shape and position. For example, bats with short snouts lack certain teeth, presumably due to a lack of space. Species with longer jaws have room for more teeth — and, like humans, their total tooth complement is closer to what the ancestor of placental mammals had.

Bats are everywhere, but they get special attention around Halloween
These nocturnal flying mammals live in cities and rural areas and in most climates around the world – and maybe even in your own backyard.
Sharlene Santana, a University of Washington professor of biology and curator of mammals at the Burke Museum, explains that there are over 1,400 species of bats spanning an incredible diversity.

Bats evolved diverse skull shapes due to echolocation, diet
In a paper published May 2 in Nature Communications, a University of Washington team reports that two major forces have shaped bat skulls over their evolutionary history — echolocation and diet — generating a huge diversity of skull shapes across 1,300 bat species today.

Scientists to create digital encyclopedia of 3-D vertebrate specimens
A $2.5 million National Science Foundation grant will daylight thousands of specimens from their museum shelves by CT scanning 20,000 vertebrates and making these data-rich, 3-D images available online to researchers, educators, students and the public. The University of Washington is a partner institution contributing most of the fish and bat scans.

Skull specializations allow bats to feast on their fellow vertebrates
Over their 52-million-year history, a few bats have evolved a taste for their fellow vertebrates. Now biologists at the University of Washington and the Burke Museum of History and Culture are shedding light on how these so-called “carnivorous bats” adapted to the daunting task of chowing down their backboned prey.

Grant will help Native American undergraduates attend first scientific meeting
Two professors from the University of Washington and Oklahoma State University have been awarded a grant from the National Science Foundation to bring six Native American undergraduate students to their first scientific meeting. The students will attend the Jan. 2016 annual meeting of the Society for Integrative and Comparative Biology in Portland, Oregon. Known commonly…
