The breeding behaviour of Gammarus duebeni

Abstract

The breeding behaviour of a population of Gammarus duebeni is investigated. The breeding system includes a precopulatory guarding phase by a male of a female and the length of this phase varies markedly over the season. Large size is not of as great advantage in reproductive competition between males as in a stream population of G. pulex. In the spring of 1981 oligochete worms, Nais elinguis, were found in the brood pouches of some females; eggs were seldom present with the worms but rather amorphous debris. The occurrence of the worms and the debris in the females' pouches coincided with the pattern of abundance of the worms previously reported.
