Effects of temperature on persistence times of native and invasive gammarid species in the stomachs of Cottus gobio
Abstract:Gastric lavage was used to investigate the effects of temperature on persistence time of two amphipod species, one native Gammarus pulex and one invasive Gammarus roeseli, in the stomachs of bullhead Cottus gobio. Persistence time was strongly influenced by temperature and prey type, such that G. pulex species degraded faster than G. roeseli.
