The diversity of amphipods in the continental shelf sediments of the southeast coast of India is dealt in the paper. Samples for the study were collected onboard FORV Sagar Sampada during Cruise Nos. 260, 275 and 290 conducted in December 2008, May 2010 and October 2011 respectively. Samples were collected at various depths (30 m, 50 m, 75 m, 100 m, 150 m and 200 m) along 6 transects namely Sin...

Epibiota were sampled on nine small jetties in the tidal, urban canals of south-east Queensland, Australia, to determine if the small fishes that are associated with these jetties prey on the epibiota on the pilings of the jetties and whether these fishes depend on the epibiota as a source of food. Epibiota was dominated by barnacles, filamentous and foliose algae and ranged in thickness from 4...

Circular rep-encoding ssDNA (CRESS-DNA) viruses are common constituents of invertebrate viral consortia. Despite their ubiquity and sequence diversity, the effects of CRESS-DNA viruses on invertebrate biology and ecology remain largely unknown. This study assessed the relationship between the transcriptional profile of benthic amphipods of genus Diporeia and the presence of the CRESS-DNA virus,...

Hyalella pauperocavae n. sp. from Huancayo, Perú, is described. Five other epigean freshwater amphipods have been described from Peru (excluding Lake Titicaca), but the lack of type material and poor descriptions do not allow the assignment of the species described here to any of the names known for the area.

The aim of this study was to assess the invasion risk of freshwater habitats and determine the environmental variables that are most favorable for the establishment of alien amphipods, isopods, gastropods, and bivalves. A total of 981 sites located in streams and rivers in Germany. Therefore we analyzed presence-absence data of alien and indigenous amphipods, isopods, gastropods, and bivalves f...

Abstract This study aimed to experimentally examine how riverbed drying and different rates of water level reduction influenced the vertical movement amphipods various sizes into subsurface sediment compositions. Using columns (mesocosms) filled with sized transparent substrates, we explored varying speeds drawdown affected stranding individuals. We hypothesised that: (1) larger individuals wou...
