Bats as Habitats for Their Ectoparasites
Ectoparasites of Paraguayan Bats
Host Characters and Ectoparasite Abundance
Ectoparasite Assemblage Structure
Co-occurrence of Ectoparasites
Host-parasite systems are excellent models to explore questions about factors that affect community and assemblage structure at both evolutionary and ecological scales. Data derived from host-parasite systems may powerfully address ecological questions because they provide a great number of replicates in conjunction with great variation in host or parasite characteristics, which can be used to explore predictions of contemporary (e.g., nestedness, Neutral Theory) and traditional (e.g., Island Biogeography, More Individuals Hypothesis, species-area relationships) ecological and evolutionary theories. Traditionally, these systems have been under-utilized; however, the amount of published research using host-parasite data is increasing quickly. In part, because these systems provide a great deal of flexibility, but also because data can be collected in conjunction with other projects and a great amount of data can be collected quickly and inexpensively. I am currently working on manuscripts involving analysis of effects of host abundance and host size on ectoparasite abundance, richness and diversity. In addition, for some host-ectoparasite relationships I am analyzing patterns of nestedness and co-occurence in an attempt to understand how interspecific interactions effect changes in assemblage structure at multiple scales (i.e., with focus on the host individual, host population, and host meta-population).
