Intraspecific phytochemical variation shapes community and population structure for specialist caterpillars
(2016)
Chemically mediated plant-herbivore interactions contribute to the diversity of terrestrial communities and the diversification of plants and insects. While our understanding of the processes affecting community structure ...
The soil mosaic hypothesis: a synthesis of multi-trophic diversification via soil heterogeneity
(2017)
Myriad unexplored mechanisms potentially drive ecological speciation and could help explain global variation in diversity. Here, we develop a novel hypothesis focused on variation in biotic, chemical, and physical properties ...
The genetic legacy of 50 years of desert bighorn sheep translocations
(2019)
Conservation biologists have increasingly used translocations to mitigate population declines and restore locally extirpated populations. Genetic data can guide the selection of source populations for translocations and ...
Absence of population structure across elevational gradients despite large phenotypic variation in mountain chickadees (Poecile gambeli)
(2017)
Montane habitats are characterized by predictably rapid heterogeneity along elevational gradients and are useful for investigating the consequences of environmental heterogeneity for local adaptation and population genetic ...
The Many Dimensions of Diet Breadth: Phytochemical, Genetic, Behavioral, and Physiological Perspectives on the Interaction between a Native Herbivore and an Exotic Host
(2016)
From the perspective of an herbivorous insect, conspecific host plants are not identical, and intraspecific variation in host nutritional quality or defensive capacity might mediate spatially variable outcomes in plant-insect ...
Fine-scale genetic structure among greater sage-grouse leks in central Nevada
(2016)
Mating systems that reduce dispersal and lead to non-random mating might increase the potential for genetic structure to arise at fine geographic scales. Greater sage-grouse (Centrocercus urophasianus) have a lek-based ...
A biogeographic perspective on the evolution of fire syndromes in pine trees (Pinus: Pinaceae)
(2018)
Our goals were to explore the relationship between biogeography and the evolution of fire-adaptive syndromes in the genus Pinus. We used a previously published time-calibrated phylogeny and conducted ancestral trait ...
