Areas of Interest
I am based in the Centre for Research in Ecological Impacts of Coastal Cities. My personal research interests could be summarised as the ecology of defence, particularly inducible defences which are mobilised by the threat of an attack or the attack itself. Predator-prey relationships are often considered a key part of ecosystem processes. I am interested in fundamental questions such as what constitutes a signal between a predator and its food items and how the signal receiver, as well as the emitter, should respond to these signals. As many induced defences incur a cost in either energy expended or lost feeding opportunities, a prey/food organism should only activate defences when needed. It is important to identify these, as yet unknown, signals in an ecological setting before trying to establish general patterns. Responses to these signals can be behavioural, such as hiding from predators; physiological, such as increasing the level of noxious chemicals in the tissues of potential food/prey organisms; or they can be structural such as growing a thicker shell. The organisms I have used in developing experimental tests of hypotheses developed from these ideas include barnacles, limpets and seaweeds.
My other interests are marine conservation and human impacts on the intertidal. Sarah Carless, my PhD student at Plymouth, has discovered that recreational use of rocky shores does indeed reduce feeding by an ecologically important predator (the oystercatcher Haematopus ostralegus), but these birds recover very quickly. So less frequent human activities on the shore are unlikely to mean these birds are deprived of food. Recreational fishing may also have an indirect effect on the marine environment. In the UK, there is a recently developed informal fishery for moulting Carcinus maenas (an intertidal crab which is invasive here in Australia) for use as bait by anglers. Emma Sheehan (another of my PhD students at Plymouth) is currently trying to understand the impact of this fishery on crab populations, the benthic infauna of estuaries and on feeding birds. Initial results show that estuaries which are fished for C. maenas seem to have higher densities of these crabs. Closing marine fisheries is a well established tool for marine conservation all over the world, but the success or otherwise of these closures is often justified in terms of fishery benefits or in terms of conservation value, a less tangible output. It is often difficult to persuade legislators and the general public of the need to conserve an environment they haven't seen or can fully engage in. With colleagues in Plymouth, I am attempting to put conservation of marine habitats such as seagrass beds and rocky subtidal reefs into a socio-economic framework by developing costed ecological goods and services (as well as fisheries benefits, the economic benefits derived from no-take angling, divers and the tourism infrastructure which that support them can be fully costed) in monetary terms. This will better inform stakeholders and enable less contentious decision making.
