Intra-specific predation and survivorship of Gammarus pulex (Crustacea: Amphipoda) within aquatic karstic habitats
Little, Sally, Tom Haslehurst And Paul J. Wood.
Abstract:
Population characteristics (abundance of individuals, body size and body mass index) of the stygophilic freshwater shrimp, Gammarus pulex (Crustacea: Amphipoda), and resource availability (particulate organic matter) within karstic subterranean, spring and riverine habitats in the English Peak District (Derbyshire) were examined. Field experiments were subsequently undertaken to characterize the intra-specific predatory behaviour (cannibalism) of the different populations. The results indicate that the natural abundance of G. pulex was lower in subterranean habitats compared to epigean habitats, although there was a similar body size range of individuals present within each habitat. Subterranean and spring populations had a lower body mass index compared to riverine populations. Experiments assessing intraspecific predation of G. pulex indicated that survivorship was significantly lower at subterranean sites compared to epigean spring and riverine sites. The results are discussed with reference to intra-specific predation within Gammarus spp. populations and resource limitation within aquatic subterranean habitats.
