Preserving deep-sea natural heritage: Emerging issues in offshore conservation and management


Andrew J. Davies, J. Murray Roberts, Jason Hall-Spencer Published in Biological Conservation (2007) Human activity in the deep sea is extending ever deeper, with recent research showing that this environment is more sensitive to human and natural impacts than previously thought. Some deep-water fish stocks have collapsed and fishing methods such as bottom trawling have [...]

Limpet grazing and loss of Ascophyllum nodosum canopies on decadal time scales


Andrew J. Davies, Mark P. Johnson, Christine A. Maggs Published in Marine Ecology-Progress Series (2007) The role of limpet grazing in preventing the development of algal canopies is a recurrent theme in intertidal ecology. Less is known about interactions of limpets with the long-term dynamics of established canopies. Aerial photographs indicate that intertidal canopy cover [...]

Coastline configuration disrupts large-scale climatic forcing, leading to divergent temporal trends in wave exposure


Andrew J. Davies and Mark P. Johnson Published in Estuarine, Coastal and Shelf Science (2006) Both climate change and the North Atlantic Oscillation (NAO) may influence coastal systems by altering wave exposure. The effects of such climatic forcing are often coherent over relatively large geographic areas. Temporal trends in wave exposure at any particular shore [...]
