Effects of two acanthocephalan parasites on the fecundity and pairing status of female Gammarus pulex (Crustacea: Amphipoda).

Acanthocephalan parasites are known to alter the reproductive biology and physiology of their hosts in various ways. In this study we investigated the influence of two acanthocephalan parasites, Pomphorhynchus laevis and Polymorphus minutus, on the fecundity and pairing success of female Gammarus pulex. The results show that P. laevis and P. minutus affect female intermediate host reproduction ...

Evolutionary study on two closed Gammarus (Crustacea, Amphipoda) species from Zagros Mountains (IRAN) using molecular methods

Mitochondrial Cytochrome Oxidase Subunit I DNA sequences are a good discriminative marker for phylogenetic studies in crustaceans and especially in amphipoda. In the present study, molecular and morphological data were analyzed to test whether Gammarus lobifer authority and Gammarus balutchi authority which one or two geographically separated but morphologically similar species. The analyses pr...

Persistence of Herbicide Residues in Gammarus Lacustris (crustacea: Amphipoda) in Prairie Wetlands

Tandem mass spectrometry (MS) was used to detect herbicide residues in wild populations of amphipods collected from microcosms spiked with a single pulse of either Avadext-BW (triallate) or HoeGrasst (diclofop-methyl) at three different concentrations (1.0, 10.0, and 100.0 mg·L21). Independent confirmations of both herbicides were obtained by spiking amphipod tissues with 50 pg of authentic sta...
