The potential for using acoustic tracking to monitor the movement of the West Coast rock lobster Jasus lalandii
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: LJ Atkinson S Mayfield AC CockcroftAlthough acoustic tracking has been used to study the movement of several species of clawed and spiny lobsters, only recent technological advances have provided sufficiently small transmitters to examine the utility of using acoustic tracking as a means to analyse... -
Sea level changes at Ascension Island in the last half century
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: PL Woodworth --- National Oceanography Centre, UK PR Foden --- National Oceanography Centre, UK DS Jones --- National Oceanography Centre, UK J Pugh --- National Oceanography Centre, UK SJ Holgate --- National Oceanography Centre, UK A Hibbert --- National Oceanography Centre, UK DL Blackman --- National Oceanography Centre, UK CR Bellingham --- National Oceanography Centre, UK VM Roussenov --- School of Environmental Sciences, UK RG Williams --- School of Environmental Sciences, UKAn exercise in ‘data archaeology’ at Ascension Island has provided an estimate of sea level change between 1955 and 2001.5 (the mid-point of a recent dataset spanning 1993–2009).

Joint Distributions for Movements of Elements in Sattolo's and the Fisher-Yates Algorithm
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Guy Louchard Helmut Prodinger Stephan WagnerSattolo's algorithm creates a random cyclic permutation by interchanging pairs of elements in an appropriate manner; the Fisher-Yates algorithm produces random (not necessarily cyclic) permutations in a very similar way. The distributions of the movements of the elements in these... -

Movements and home range of the gaboon adder, Bitis gabonica gabonica, in Zululand, South Africa
Item type: Journal Article • Journal: African Zoology • Authors: I. J. Linn --- School of Biological and Conservation Sciences, University of KwaZulu-Natal, South Africa M. R. Perrin --- School of Biological and Conservation Sciences, University of KwaZulu-Natal, South Africa T. Bodbijl --- School of Biological and Conservation Sciences, University of KwaZulu-Natal, South AfricaGaboon adders are active throughout the year, but are largely sedentary. In their prime habitat of forest–thicket–grassland mosaic in Zululand their normal foraging movements are short range, punctuated by long periods of inactivity. Occasional long distance movements suggest changes in... -
