Mechanisms underlying the costs and benefits in grass-fungal endophyte symbioses
Nearly all plants have developed symbiotic associations with microbes above- and belowground. These symbionts often alter the ecology of their hosts by enhancing nutrient uptake, increasing stress tolerance, or providing ...
The Consequences of Plant Species Diversity and Genetic Diversity for Populations, Communities, and Ecosystems
Plant species diversity plays an important role in structuring communities and mediating ecosystem processes. Experiments have shown increasing plant species richness increases primary productivity, arthropod species ...
Kinship and the evolution of altruism in social amoebae and A model for the evolution of kin-limited interactions
For decades, social amoebae have served as a model supporting broader theories of social behavior. Owing to their peculiar aggregative life cycle, it has seemed reasonable altruism in social amoebae is possible because ...
VARIATION IN SPECIES INTERACTIONS AND THEIR EVOLUTIONARY CONSEQUENCES
Species interactions restrict or promote population growth, structure communities, and contribute to evolution of diverse taxa. I seek to understand how multiple species interactions are maintained, how human altered species ...
Examining competitive interaction between Rasberry crazy ants (Paratrechina sp.nr. pubens) and red imported fire ants (Solenopsis invicta) using laboratory and field studies
Studying nonnative species soon after their introduction is critical to understanding their risk of becoming widely invasive and determining effective methods of control. I conducted laboratory and field experiments on the ...
Anoplolepis gracilipes invasion of the Samoan Archipelago: Can mutualisms with native species amplify ecological consequences?
Integrating mutualism into the study of ecological communities is likely to be critical to understanding community dynamics and to predict the consequences of anthropogenic changes to ecosystems. Invasive species are among ...
