​Evolutionary Ecology of Small Mammals
I am an evolutionary ecologist interested in how small mammals allocate resources towards reproduction in terms of time and energy as well as mating decisions.   As reproduction and nutrition are intertwined my research also often includes consideration of animal diets. 


​I am delighted to announce that I have joined the Department of Biology at  New Mexico State University.

We are the BEBOP Lab:
Behavioral Ecology and Bat Organismal Physiology.

I  am looking for enthusiastic students (MS or PhD) as well as undergraduates.  For more information click HERE.

​
​What I spend my time thinking about....

Evolutionary Physiological Ecology

• What constitutes a reproductive delay and why might this physiology evolve?
• What is female sperm storage and how did it evolve?
• What are the costs and trade-offs associated with reproduction?
• Why might reproductive delays have evolved?
• What are the consequences of specialised reproductive modes (delays)?

Sexual
​Selection

• How do female reproductive physiologies impact sexual selection?
• Do bats exhibit sexual conflict?
• Do males co-evolve in the context of female reproductive strategies?
•What evidence of sexual selection do we see in bat genitalia?

Nutritional
Ecology

​• What do animals eat in extreme environments?
• How do animals navigate toxins in their foods?
• How does diet change in relation to reproduction?
•How does ecology impact the composition of milk in different mammals?

Mentoring
Future ​Biologists

•What is the role of reproductive pigmentation?  (Jen Delmore-Silva- published this year!)
•How does creosote tolerance differ between woodrat populations? (KayLene Yamada)
•How do specialist kangaroo rats shift their diets with range land encroachment?  (Sydney Stephens)
• Do females evolve morphologies to defray the costs of harmful male genitalia?  (Jennifer Wen)
• What do lactating and pregnant frugivorous bats eat?  (Caitlin Sanchez)
