Functional Components of Ant Wings

Very little is known about how reproductive ants use their wings for flight. They are widely considered “poor fliers”. My current work examins basic feartures for flight across a variety of species. (MTK)

Bat Wing Shape

Digit placement helps bats modulate wing shape during flight. I’m interested in how the placement of wing anatomy facilitate differnt flight modes, and how wing shape is generated over disparate taxa with convergent flight modes. (MTK)

Red Bats in the Caribbean

Red Bats are widely distributed and speciated throughout the Americas, but how these populations vary over their range have interesting biographical implications. (MTK)

Egg Morphology

The movement, stability and viability of avian eggs rely heavily on their morphology. My current work examines the relationship between geometric properties of Auk eggs and their nesting stratagies.

US Western Bats: A (VISUAL) Dichotomous Key

I'm currently working on a visual dichotomous key for bats found in the Western United States, to pair with the US Eastern Bat key, in the link below. Like the Eastern key, the visual diagrams and example images will help professionals to identify species in-hand.
