Using magneto-resistive sensors to monitor animal behaviour: a case study using limpets.
Magnetic sensors have existed for many years and are widely used in different applications such as navigation systems, automation, position detection and current detection (amongst others). In this paper we explore a unique application of underwater magnetic sensing using a magneto-resistive sensor to monitor animal behaviour.
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 raised international [...]
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 has declined [...]
