Mitochondrial Cytochrome Oxidase Subunit I DNA sequences are a good discriminative marker for phylogenetic studies in crustaceans and especially in amphipoda. In the present study, molecular and morphological data were analyzed to test whether Gammarus lobifer authority and Gammarus balutchi authority which one or two geographically separated but morphologically similar species. The analyses pr...

First records of peracarid crustaceans obtained from the Cayo Matías Ocean Blue Hole, southwestern Cuba, are documented. In addition, two new species of isopod and amphipod are herein described. Gnathia micheli n. sp. (Isopoda, Gnathiidae) and Boca normae n. sp. (Amphipoda, Aristiidae) were associated with filamentous algae at a depth of 20 m. Both represent the first report for a blue hole and...

The genus Paracallisoma (Crustacea: Amphipoda) is revised and the type species, Paracallisoma alberti is redescribed based on holotype material supplemented with new material from the region of the type locality. This revision results in the establishment of two new genera, Pseudocallisoma gen. nov. and Haptocallisoma gen. nov., and the description of a new species of Haptocallisoma and a new s...

The presence of diverse biological substrates adds complexity to coastal landscapes and increases the number of ecological niches that can be used by the mobile epifauna. Studies on the influence of structural complexity have focused mainly on algal host species, but there is little information about the influence of intraspecific structural variation on the associated mobile epifauna. In this ...

A response is given to criticisms in a recent paper of the validity of the amphipod suborder Senticaudata. The tacitly assumed status of truth implied in some molecular higher phylogenies is called in to question.

An accoiMt of the past 50 years of research carried out on Amphipoda by the Central Marine Fisheries Research Institute and most relevant works carried out on the topic from the Indian seas are presented. The paper highlights the qualitative and quantitative composition, distribution in space and time and the taxonomy of planktonic :imphipods of neritic and oceanic waters of Indian region as we...

The collection of zooplankton swimmers and sinkers in time-series sediment traps provides unique insight into year-round interannual trends population dynamics. These samples are particularly valuable remote difficult to access areas such as the Arctic Ocean, where from ice-covered season rare. In present study, we investigated composition based on collected by at water depths 180–280, 800–1320...
