Predators vs. alien: differential biotic resistance to an invasive species by two resident predators [PDF]

open access: yes, 2013
The success of invading species can be restricted by interspecific interactions such as competition and predation (i.e. biotic resistance) from resident species, which may be natives or previous invaders.

Contrasting sensitivities to toxicants of the freshwater amphipods Gammarus pulex and G. fossarum

open access: yes, 2010
Amphipods are an important component of freshwater ecosystems. They are very often used in ecotoxicology, particularly the freshwater amphipod Gammarus pulex.

Living on the dark side? Investigations into under-ice light climate and sympagic amphipods [PDF]

open access: yes, 2022
The manuscripts of the dissertation presented here encompass several aspects of adaptations in ice-associated amphipods, focussing mainly on their ability to cope with increased light levels, including the ultraviolet radiation (UVR), under thinner or ...

An Amphipod Invasion [PDF]

open access: yesNature, 1913
MANY specimens of a small amphipod crustacean, Euthemisto compressa, Goes, have been forwarded to me by Mr. T. H. Nelson, of Redcar. On May 23 and 24 these were washed ashore in incredible numbers on the coast of Yorkshire, where they lay from Saltburn to Teesmouth—a distance of ten miles in drifts several inches deep.

Invasive Ponto-Caspian amphipods and fish increase the distribution range of the acanthocephalan Pomphorhynchus tereticollis in the river Rhine

open access: yes, 2012
Non-indigenous species that become invasive are one of the main drivers of biodiversity loss worldwide. In various freshwater systems in Europe, populations of native amphipods and fish are progressively displaced by highly adaptive non-indigenous ...

Swarms of Amphipods [PDF]

open access: yesNature, 1893
ONCE last winter on entering the laboratory here after it had been shut up for a few days, we found the floor, tables, shelves, window-ledges, and even dishes on the highest shelves, covered with great numbers of dead amphipods. These were found to be Orchestia gammarellus (the shore-hopper).

Species identification and connectivity of marine amphipods in Canada’s three oceans

open access: yesPLoS ONE, 2018
Monitoring the distribution of marine biodiversity is a crucial step to better assess the impacts of global changes. Arctic marine fauna is dominated by amphipods in terms of abundance and biomass.
