Comparative analysis of the 16S rRNA gene and fluorescent in situ hybridization (FISH) was used to identify epibiotic filamentous bacteria living on the marine amphipod crustacean Urothoe poseidonis. The epibionts belong to the gamma proteobacteria and represent a novel marine phylotype within the genus Thiothrix. FISH and denaturing gradient gel electrophoresis revealed that the Thiothrix fila...

Four species of amphipods from the families Aoridae and Maeridae were collected from Thai Waters in 2011. Three species, Grandidierella phetraensis sp. nov., Ceradocus andamanensis sp. nov. and Parelasmopus siamensis sp. nov. are new to science and Bemlos quadrimanus (Sivaprakasam, 1970) has not been previously reported from Thai Waters. Their characters are described and illustrated. All speci...

Abstract Dramatic genome size variation exists across the Tree of Life. Some crustacean groups, such as amphipods, have sizes that correlate with body size, temperature, and water depth, indicating may be constrained due to physiological pressures. This indicate a general “genome-temperature-size” rule in ectotherms, which body-size latitude predictive size. We examined relationship between rep...

Holopelagic animals were long assumed to have widespread geographic distributions due the failure recognize hydrographic species' barriers in open ocean. As molecular genetic tools are more commonly used study ocean's inhabitants, diversity is found be substantially higher than when inferred from morphological taxonomies alone. Here, we investigate and of hyperiid amphipods within genus Paraphr...

Numerous specimens of poorly known pleustid amphipod Pleusymtes japonica (Gurjanova, 1938) (Crustacea: Amphipoda: Pleustidae: Pleusymtinae) were found in association with large hermit crab Pagurus ochotensis Brandt, 1851 (Crustacea: Decapoda: Paguridae) near Furugelma Island in the Sea of Japan. This is the first report of the species in association with hermit crabs. Amphipods were found livin...

Hyporheic interstitials are ecologically dynamic and often neglected aquatic environments. In this study, groundwater amphipods (Niphargidae, Pseudoniphargidae Crangonyctidae) were sampled in hyporheic throughout Luxembourg The Greater Region specimens analyzed by DNA barcoding. Sites characterized gravel or coarse sand high flow velocities of incoming water the most species- specimen-rich. A t...
