Hydrothermal activity lowers trophic diversity in Antarctic sedimented hydrothermal vents [PDF]

open access: yes, 2016
Sedimented hydrothermal vents are those in which hydrothermal fluid vents through sediment and are among the least studied deep-sea ecosystems. We present a combination of microbial and biochemical data to assess trophodynamics between and within ...

Molecular Phylogeny and Biogeography of the Genus Pseudomma (Peracarida: Mysida) [PDF]

open access: yesJournal of Crustacean Biology, 2004
Abstract We used DNA sequences from 18S rDNA (808 bp) and COI mtDNA (599 bp) to infer evolutionary history of northern groups of the deep-sea mysid genus Pseudomma. The V4–V7 regions of 18S show an average of 1.31% sequence divergence between species.

Unexpected pathway for intercontinental movement into the Nearctic revealed by phylogenetic analyses

open access: yesZoologica Scripta, Volume 54, Issue 4, Page 562-574, July 2025.
Abstract Much of North America's freshwater biodiversity is derived from Palearctic lineages. Isopods of the Holarctic family Asellidae are among the most widespread and diverse freshwater crustaceans, but Nearctic species are poorly studied. We examined the evolutionary history of the family, utilizing Sanger sequencing of mitochondrial and nuclear ...

Crab‐associated amphipods from the Falkland Islands (Crustacea, Peracarida) [PDF]

open access: yesJournal of Natural History, 2005
Four species of associated amphipods were collected from the lithodid crab Paralomis granulosa in the Falkland Islands: Jassa kjetilanna n. sp. (Ischyroceridae), Gammaropsis monodi (Schellenberg, 1931) (Photidae), Aora karibu n. sp. (Aoridae), and Paramoera falklandica n. sp. (Eusiridae s.l.). The Gammaropsis was also found on the majid crab Eurypodius
