pdf 05. Feral Xenopus laevis in South Wales


Open Access


Authors: G. John Measey And Richard C. Tinsley

Abstract: Despite its prominence as the "standard laboratory amphibian", the ecology of the African clawed frog, Xenopus laevis, has been neglected. Feral populations have been documented in several countries with Mediterranean climates, but established populations are also known from the UK. Long term studies of individually-marked X. laevis in South Wales reveal large demographic fluctuations and the ability to migrate overland. Maximum longevity recorded from recapture of marked individuals was 14 years. Diet analysis demonstrates a major reliance on benthic invertebrates and zooplankton components of the pond fauna. Skeletochronological studies of growth rings in bone showed that lines of arrested growth are formed annually and allow calculation of age. Data on population age structure indicate successful recruitment is infrequent, with dominant cohorts originating in perhaps only four summers during the past 20 years.
