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 ...
Overstory-derived surface fuels mediate plant species diversity in frequently burned longleaf pine forests
(2017)
Frequently burned low-latitude coniferous forests maintain a high-diversity understory. Longleaf pine (Pinus palustris Mill.) forests and woodlands have exceptionally high diversity at fine scales and very frequent fire ...
Interaction Diversity Maintains Resiliency in a Frequently Disturbed Ecosystem
(2019)
Frequently disturbed ecosystems are characterized by resilience to ecological disturbances. Longleaf pine ecosystems are not only resilient to frequent fire disturbance, but this feature sustains biodiversity. We examined ...
Global weather and local butterflies: variable responses to a large-scale climate pattern along an elevational gradient
(2015)
Understanding the spatial and temporal scales at which environmental variation affects populations of plants and animals is an important goal for modern population biology, especially in the context of shifting climatic ...
Trait-mediated trophic cascade creates enemy-free space for nesting hummingbirds
(2015)
The indirect effects of predators on nonadjacent trophic levels, mediated through traits of intervening species, are collectively known as trait-mediated trophic cascades. Although birds are important predators in terrestrial ...
Phytochemical diversity drives plant-insect community diversity
(2015)
What are the ecological causes and consequences of variation in phytochemical diversity within and between plant taxa? Despite decades of natural products discovery by organic chemists and research by chemical ecologists, ...
Simulated tri-trophic networks reveal complex relationships between species diversity and interaction diversity
(2018)
Most of earth's biodiversity is comprised of interactions among species, yet it is unclear what causes variation in interaction diversity across space and time. We define interaction diversity as the richness and relative ...
Changing interactions among persistent species as the major driver of seasonal turnover in plant-caterpillar interactions
(2018)
beta diversity of herbivorous insects in the tropics is usually very high, and there is often strong dissimilarity in herbivore species composition across different spatial scales and different abiotic gradients. Similarly, ...
Across Multiple Species, Phytochemical Diversity and Herbivore Diet Breadth Have Cascading Effects on Herbivore Immunity and Parasitism in a Tropical Model System
(2018)
Terrestrial tri-trophic interactions account for a large part of biodiversity, with approximately 75% represented in plant-insect-parasitoid interactions. Herbivore diet breadth is an important factor mediating these ...
