The delimitation of the spatial equivalent of isolated populations or interacting sets of local populations is crucial for conservation management. In Amphibia, spatial organization in metapopulations requires knowledge on the individual variation of

The natterjack toad ( Bufo calamita) is an endangered species in Britain and has been legally protected since 1975. This amphibian suffered a major decline during the first half of the twentieth century, due partly to habitat destruction but mostly t

The significance of predation and aquatic habitat structures to the survivorship of natterjack toad Bufo calamita larvae was investigated by manipulating predator numbers and pond characteristics in a series of replicated semi-natural pools over thre

Two congeneric anurans with highly overlapping geographical ranges, Bufo bufo and B. calamita, were investigated with respect to isolating mechanisms during the terrestrial phase of life in the three habitat types in which both species occur in Brita

Abstract. The behaviour of male and female natterjack toads in an isolated population of about 100 adults in Hampshire, U.K. was investigated over a period of 5 years. Virtually all animals were individually identifiable (by toe-clipping and throat-s

Abstract We have investigated the dynamics of an isolated population of natterjack toads (Bufo calamita) over the period 1972-1991. During this time the habitat was manipulated by clearance of scrub woodland and by creation and restoration of ponds.

We have investigated methods for finding natterjack toads (Bufo calamita) outside the breeding season at a range of sites in England. Success in locating toads in burrows or in other natural refugia was very variable between sites, depending on the n

The population densities of adult natterjack toads (Bufo calamita, Laurenti) were found to vary over an order of magnitude between different localities for this species in Britain. Adult toad population density correlated positively with average toad
