Complete mitochondrial genome (mitogenome) sequences can provide useful and varied information for evolutionary phylogenetic studies. We report the first complete mitogenome sequence of bumblebee shrimp (Gnathophyllum americanum). The is 15,842 bp in length contains 13 protein-encoding genes, 2 ribosomal RNA 22 transfer genes. nucleotide composition was as follows: A,36.72%; T,29.62%; C,21.0%; ...

Aim We conduct the first model-based assessment of biogeographical subdivision Eurasian Arctic seas to (1) delineate spatial distribution and boundaries macrobenthic communities on a seascape level; (2) assess significance environmental drivers community structures; (3) compare our modelling results historical classifications; (4) couple model climate scenarios changes project potential shifts ...

BACKGROUND The Ice krill, Euphausia crystallorophias is one of the species at the base of the Southern Ocean food chain. Given their significant contribution to the biomass of the Southern Ocean, it is vitally important to gain a better understanding of their physiology and, in particular, anticipate their responses to climate change effects in the warming seas around Antarctica.

Abstract The “ Iberobathynella group”, or Iberobathynellini tribe, is a complex of six genera consisting 33 nominal species and several cryptic with an amphiatlantic distribution (in Europe, North Africa America). A modern systematic revision this group subterranean crustaceans presented here. phylogenetic biogeographic study using morphological molecular data (mitocondrial coi nuclear 18S) was...

—A new species of leptostracan crustacean, Nebalia gerkenae, is described from Bennett Slough, Monterey County, California. The species is similar to N. hessleri from deeper waters off La Jolla, California. It differs from N. hessleri in the shape and color of the pigmented region of the eyes, armature of the antennule and antenna, the degree that the carapace covers the abdominal somites, dent...
