Dispersal of bacterivorous protozoa affects pitcher plant bacterial communities
Not all predators disperse at the same rate. Predator dispersal regimes can structure the composition, diversity and assembly process of predators but also of their prey. We investigated the differences in dispersal regimes of bacterivorous protozoans inhabiting the leaves of the purple pitcher plant (Sarracenia purpurea). Come see my talk at ESA!

Competitive context evolution of bacterivorous protozoa and its influences on bacterial communities - with T.E. Miller and O. Mason.
Rapid evolution and ecological processes can co-occur with important consequences for local and regional diversity patterns. We set out to uncover the role of evolution in community context and its consequences for trophic dynamics.

Sources of colonists: species pools driving crab-associated microbial communities
How do different species pools interact with habitat filters? Ecological theory suggests that species pool size and composition will have important effects on local communities. This study investigated how bacteria from different types of bacteria colonize habitats within species of crabs (Uca sp).

Isopod behavioral ecology
Animal behaviour is a critical aspect for survival. Dispersal is a critical aspect of behaviour that may impact meta-population and -community patterns. Dispersal is the outcome of integrating behavioural aspects like orientation, movement and conspecific attraction. We explored the interaction between these behavioural mechanisms and environmental cues in driving marine isopod behaviour.

Bacteria in marsh sediment is driven by fiddler crabs
Bacterial communities in the forest sediments drive nutrient turnover. However, fiddler crabs and other detritivores are instrumental in altering sediment biochemistry. Here, we show that fiddler crabs consume bacteria reducing richness but also serve as a refuge for certain species.
