Topic: The role of native and invasive amphipods in freshwater systems
B.Sc. 1st class (Hons),
Zoology, Queens University of Belfast (1994-1998)
I have a wide range
of research interests; my thesis work focused on the importance of the
functional trophic role of aquatic amphipods in driving patterns in freshwater
invertebrate and fish communities at a range of spatial scales. In particular,
I am interested in the role of predation as a direct and indirect mechanism,
and also, how the balance of a dual detritivore/ predator role may drive
impacts of non-indigenous versus native amphipods.
More recently my focus has shifted to the utility of riverine amphipod invasions as models of energy flow in stream ecosystems. By displacing native amphipods and other invertebrate species, and by differing in resource use and/ or assimilation efficiency, non-indigenous amphipods have the potential to alter the flux of energy in a system, particularly if they impact functionally important native species.
As the rate of species
invasions increase globally, it is essential probe the origins and pathways
that have facilitated their range expansions. This information provides
for a comprehensive understanding of associated vectors and benefits management
of invasions through risk assessment and prevention. Accurate identification
of source populations also enables the formation and testing of hypotheses
related to many fundamental tenets of invasion ecology. For example, the
importance of genetic diversity, hybridisation and enemy release as mechanisms
underlying invasion success. In many cases, invading species undergo major
habitat transitions and so understanding genetic and phenotypic responses
can shed new light on the ability of colonising species to evolve rapidly
during range expansions. Given the widespread native ranges of many invertebrate
species, coupled with the difficulty involved using traditional taxonomy
in their identification, phylogeographic studies can be of benefit in tackling
many of the above problems. I am currently studying the phylogeography
of a native N. American estuarine invertebrate that has invaded freshwater
habitats in Europe and North America. My goal is to assess invasion sources
and pathways and the processes that have facilitated adaptation to freshwater.
