The urosome of the Pan- and Peracarida [PDF]

Contributions to Zoology, 2006
We have examined the caudal regions of diverse peracarid and pancarid malacostracans using light and scanning electronic microscopy. The traditional view of malacostracan posterior anatomy is not sustainable, viz., that the free telson, when present, bears the anus near the base.

Gaps and Data Ambiguities in DNA Reference Libraries: A Limiting Factor for Molecular-Based Biodiversity Assessments Using Annelids as a Case Study. [PDF]

Ecol Evol
Regional DNA reference libraries are crucial for molecular biodiversity assessments, yet they remain incomplete, limiting their effectiveness. Using annelids from the Arabian Peninsula as a case study, we identified considerable gaps in species coverage and minimal representation in public databases.

Diversity and distribution of the Isopoda (Crustacea, Peracarida) of Kuwait, with an updated checklist. [PDF]

Zookeys, 2022
Thirty-eight species of Isopoda, belonging to 13 families and 29 genera, are listed from Kuwait based on previous literature records (of 17 species) and collections carried out along Kuwait’s coastal and subtidal zones during the present study. The majority of species belongs to the suborder Cymothoida (23), followed by Sphaeromatidea (9), Oniscidea (3)

Food intake of early juvenile western Baltic cod (Gadus morhua) during settlement transition. [PDF]

J Fish Biol
Abstract This study examines the gut contents of 203 early juvenile Atlantic cod [17–101 mm ± 18.48 mm standard deviation (SD)] from the Western Baltic Sea (ICES Subdivision 22) collected between 2020 and 2022. According to the observed prey (proportion of pelagic, intermediate and benthic items) in the cod guts, settlement transition from a pelagic to

Taking eDNA underground: Factors affecting eDNA detection of subterranean fauna in groundwater

Molecular Ecology Resources, Volume 23, Issue 6, Page 1257-1274, August 2023., 2023
Abstract Stygofauna are aquatic fauna that have evolved to live underground. The impacts of anthropogenic climate change, extraction and pollution on groundwater pose major threats to groundwater health, prompting the need for efficient and reliable means to detect and monitor stygofaunal communities.

Neurochemical diversity in the central olfactory pathway of the crustacean Parhyale hawaiensis (Amphipoda): evolutionary implications

Journal of Comparative Neurology, Volume 531, Issue 10, Page 1032-1056, July 2023., 2023
Neurochemical diversity in the central olfactory pathway of Parhyale hawaiensis Abstract In mandibulate arthropods, the primary olfactory centers, termed olfactory lobes in crustaceans, are typically organized in distinct fields of dense synaptic neuropils called olfactory glomeruli.

Sexual selection and predation drive the repeated evolution of stridulation in Heteroptera and other arthropods

Biological Reviews, Volume 98, Issue 3, Page 942-981, June 2023., 2023
ABSTRACT Acoustic and substrate‐borne vibrations are among the most widely used signalling modalities in animals. Arthropods display a staggering diversity of vibroacoustic organs generating acoustic sound and/or substrate‐borne vibrations, and are fundamental to our broader understanding of the evolution of animal signalling.

MITOCHONDRIAL GENES AND ISOPOD PHYLOGENY (PERACARIDA: ISOPODA) [PDF]

Journal of Crustacean Biology, 2002
Abstract Molecular data are used to test whether (1) Phreatoicidea are the earliest derived living isopods, and (2) the long-tailed isopod morphology is the derived condition within the Isopoda. Small and large subunits of the mitochondrial ribosomal genes (12S- and 16S rDNA), and cytochrome oxidase c subunit I (COI) are used as a case study for ...

Crustacea: Malacostraca — Syncarida, Peracarida: Isopoda, Tanaidacea, Mictacea, Thermosbaenacea, Spelaeogriphacea Crustacea: Malacostraca — Peracarida Amphipoda, Cumacea, Mysidacea [PDF]

Crustaceana, 2009
The second genus and species of Spelaeogriphacea, Potiicoara brasiliensis, is described (type-locality: Brazil, Mato Grosso do Sul, Bonito, Gruta Azul). The specimens were found swimming in a lake 50 m inside the cave entrance. The new genus is distinguished from Spelaeogriphus Gordon by having a shorter carapace, mandibular palp three-segmented ...
