Diversity of and biogeographic insights into the Atlantic Eocuma (Cumacea: Peracarida)

The European Zoological Journal, 2022
The Gulf of Guinea is characterised by a complex hydrology and supports a high species diversity. A recent study has indicated that the area can be considered a refuge for rare taxa. Intensive sampling off the coast of Ghana (Gulf of Guinea) in 2012 on board the R/V F.

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

Zoologica 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 ...

The phylogenetic position of the Isopoda in the Peracarida (Crustacea: Malacostraca) [PDF]

Arthropod Systematics & Phylogeny, 2009
The sister group to the isopod crustaceans remains a controversial proposition. Previous studies have used idealised composite taxa or few exemplars, resulting in confl icting assertions about the placement of the Isopoda among the Malacostraca. A recent morphological study argued for an Amphipoda-Isopoda clade, whereas a molecular study using SSU rDNA

Phylogeny of the fascinating and frustrating Peracarida: the past, the present and the future [PDF]

Arthropod Systematics & Phylogeny
Peracarida (Arthropoda: Crustacea) is one of Earth’s most strikingly diverse animal groups. Often compared with their relatives, the decapods (crabs, shrimp, and lobsters), a better comparison would be with the hyperdiverse insects: small bodies ...

Assessing the Complex Effects of the Invasive Amphipod Dikerogammarus villosus on Leaf Litter Breakdown in Rivers

Freshwater Biology, Volume 70, Issue 2, February 2025.
ABSTRACT Allochthonous organic matter is an essential resource of aquatic food webs, and freshwater amphipods, particularly species of the genus Gammarus, play a significant role in leaf litter decomposition. However, this important ecological function may be affected by the invasion of alien amphipods such as Dikerogammarus villosus, which has been ...

A replacement name for Dayus Gerken, 2001 (Crustacea, Peracarida, Cumacea), preoccupied by Dayus Mahmood, 1967 (Insecta, Hemiptera, Cicadellidae)

ZooKeys, 2014
A replacement name is proposed for genus Dayus Gerken, 2001 (Crustacea: Peracarida: Cumacea), preoccupied by Dayus Mahmood, 1967 (Insecta: Hemiptera: Cicadellidae). The following changes are proposed: Jennidayus new replacement name = Dayus Gerken, 2001 (
