A review of the reproductive bionomics of aquatic gammaridean amphipods: variation of life history lifespan of females) for 302 populations of aquatic gammaridean amphipods, representing 214 species in 16 superfamilies, were reviewed. The variation of these traits, of lifetime potential fecundity (i.e. the number of embryos produced per female lifespan) and of reproductive potential (i.e. the num

Ingestion of live filamentous diatoms by the Great Lakes amphipod, , sp.: a case study of the limitest that earlier studies of pontoporeiid gut contents may seriously underestimate the importance of algal components in the amphipod’s diet and imply that . sp. growth and production may be more closely linked to primary production than previously thought.

MANIA

Is the oostegite structure of amphipods determined by their phylogeny or is it an adaptation to thegs than those with narrow oostegites. It is concluded that following the evolution of the major amphipod groups, the oostegites were modified as egg sizes have changed as part of the reproductive strategies of the species within these groups.
