Freshwater Gammarus species from Europe, North Africa and adjacent regions of Asia (Crustacea-Amphipoda). Part II. Gammarus roeseli-group and related species
TLDR
The Gammarus pulex-group is revised, based on rich material from Europe, North Africa, Asia minor and adjacent areas, and certain stable characters can be distinguished within some taxa, such as the structure of the mandibular palp.
Drastic changes in the amphipod fauna (Crustacea) of Dutch inland waters during the last 25 years
TLDR
Electrophoretic tests give evidence that a second invasion of Gammarus tigrinus, this time from Germany, is taking place.
On members of the Gammarus pulex-group (Crustacea- Amphipoda) from western Europe
La variabilite morphologique des Gammares du groupe pulex et la confusion concernant la position systematique des differentes formes de ce groupe, deja demontrees par l’auteur en 1970, l’ont conduit
The problem of European freshwater populations of Gammarus duebeni Liljeborg, 1852
TLDR
It is shown that significant morphometrical differences exist between the two forms, and it is probable, that G. duebeni was the oldest freshwater species in that area (presumably originating from mixohaline or marine ancestors in one of the earlier interglacial periods), and thatG.
The Echinogammarus berilloni-group, a number of predominantly Iberian Amphipod species (Crustacea)
The morphological diversity within the species Echinogammarus berilloni (Catta, 1878), stressed by Spandl (1926), Margalef (1956) and Pinkster (1969) was a motive to sample systematically in drainage

  • 1 December 1975
TLDR
If G. tigrinus tends to occupy the same habitats as the originalGammarus species and it is subjected to the same density controlling factors then its greater reproductive capacity will enable this species to outnumber and gradually replace the three indigenous species.
Upstream and downstream migrations in relation to the reproductive cycle and to environmental factors in the amphipod, Gammarus zaddachi
1. The real identity has been studied of juvenile gammarids, that were found in the fresh-water tidal region of the River Slack (France), 3 to 4 km inland of the mouth of its estuary. At the outset,
Western European species of the presumed Baikal-genus Eulimnogammarus (Crustacea – Amphipoda), with description of a new species from Spain
Plus de 150 echantillons de Gammaridae ont ete collectionnes dans la region septentrionale de l’Espagne pendant l’ete de 1969. Des representants du genre Eulimnogammarus furent trouves dans cinq
