Research Interests

The role of parasitism in host-host interactions, community structure and the outcome of biological invasions

Pond dipping

The role of parasitism in host-host interactions and community structure

Parasites have detrimental effects on the host individuals and populations. However, the outcome for communities is more complex. By mediating interactions between hosts, parasites may act as keystone species within a community. Currently we are focusing on trait mediated indirect effects of parasites and their outcome for host-host interactions such as competition and predation

   

Biological invasions

Changing habitats and anthropogenic introductions of non- native species are a threat to native biodiversity. We are working with the Environment Agency and Tarmac to investigate the use of ARK sites in the conservation of native species and to develop protocols the restoration of quarries for aquatic conservation.
 
Biological invasions pose a major threat to biodiversity and economics. The spread of new parasites can devastate native biota, whilst escape from parasites may benefit an invader. On the other hand, parasites may slow the process of invasions and maintain native biodiversity. Recently we have demonstrated that parasites can mediate predation between native and invading species, and influence the success of an invasion. Currently we are using theoretical and empirical approaches to study the role of parasites in invasion success and the outcome for community structure. 

 

 
The evolution of sexual strategies
Parasitic sex ratio distorters are widespread in arthropod hosts and have been implicated in speciation and the evolution of novel mechanisms of sex determination. Sex ratio distorters are vertically transmitted from host mother to offspring. By distorting host sex ratios towards females, these parasites increase their spread. We are interested in the evolution of vertical transmission and feminisation in the Microspora (a phylum of eukaryotic parasites). Phylogenetic analyses reveal that vertical transmission occurs in all major lineages and that feminisation has arisen more than once. Currently we are using in situ hybridisation to map parasite distribution in host embryos and investigate the mechanism of feminization.
