Species history, population genetics, and behavioral reproductive isolating mechanisms of two Chihuahuan desert katydids (Orthoptera: Tettigoniidae)
(2015-05)
Understanding the mechanisms and evolutionary processes that lead to reproductive isolation between populations is the major goal of speciation research. Here, I integrated approaches from phylogenetics, population genetics, ...
Effects and associations of the production of the biofuel crop Brassica napus on wild invertebrate pollinator communities in the South Central United States
(2015-12)
The addition of biofuel crops to the agricultural landscape is drastically changing habitats around the world with unknown environmental consequences. Agricultural conversion of land negatively affects pollinators which ...
Possible sexual selection in pre-reproductive hatchling collared lizards (Crotaphytus collaris)
(2015-07)
We studied the possible adaptive significance of precocial sexual signaling in collared lizard hatchlings. Male hatchlings display intense dorsolateral orange bars at hatching or within the first weeks of life. Hatchling ...
