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 ...
Population Dynamics of Heritable Symbionts when Accounting for the Life History Complexity of their Host
I developed theory and experiments to understand how complex life cycles of a host affect the dynamics of their heritable symbionts, important ecological and evolutionary agents. With symbiont persistence and prevalence ...
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 ...
Evolutionary responses to global change: an experimental test of the effect of altered precipitation on hybridization rates in sunflower (Helianthus)
Climate change is rapidly altering natural ecosystems. Plastic and adaptive responses to climate change (i.e., range shifts and phenology) have been widely noted across taxa. However, the effects of climate change on ...
