Amphipod ( Gammarus minus ) responses to predators and predator impact on amphipod density

Oecologia, 1998
Recent theoretical work suggests that predator impact on local prey density will be the result of interactions between prey emigration responses to predators and predator consumption of prey. Whether prey increase or decrease their movement rates in response to predators will greatly influence the impact that predators have on prey density.

Lipids of Antarctic Ocean Amphipods: Food Chain Interactions and the Occurrence of Novel Biomarkers

Marine Chemistry, 2001
Antarctic hyperiid (Themisto gaudichaudi, Hyperia macrocephalus, and Primno macropa) and gammarid amphipods (Eusirus perdentatus and Orchomene rossi) were collected near Elephant Island, located in the South Shetland Islands, during January and February ...

Integumental Pigments of the Amphipod, Jassa

Nature, 1970
THE integumental pigments of the isopod Crustacea are ommochromes1,2, but by contrast the effectively similar colour of the amphipod Gammarus is due to carotenoids3, probably in the form of carotenoproteins. The implication of these findings was that this constitutes a general distinction between these rather closely related orders.

The integumental organs of amphipods

Journal of the Marine Biological Association of the United Kingdom, 1975
Some integumental organs of Amphipoda have been briefly described by Bate & Westwood (1863). Their diagrams are extremely small and, in some cases, inaccurate. Fleminger (1973) described the integumental organs of calanoid copepods of the genus Eucalanus. He shows that these are distributed over the body in a pattern peculiar to each species. Bate &

The Higher Classification in Amphipods

Crustaceana, 1975
Bousfield's recent book "Shallow-water Gammaridean Amphipoda of New England' ' advances that faunal element into sharp focus with excellent illustrations, workable keys and extensive descriptions. Within its faunal province, the value of this work is uncontested.

Luminescence in Marine Amphipods

Nature, 1967
ALTHOUGH bioluminescence is a common phenomenon among many marine Crustacea1,2, records of its occurrence among the Amphipoda are few. Of those records that exist, all the actual observations of light production (except perhaps that of Bowman on Parapronoe, as cited in ref.

Amphipods in the Surf Plankton

Journal of the Marine Biological Association of the United Kingdom, 1970
The study of diurnal vertical movements of macro-plankton (Russell, 1925) showed that many organisms, including amphipods migrated to the surface of the sea at night. Since this work there have been several papers reporting vertical movements in intertidal waters.
