Tanaidáceos (Crustacea: Peracarida) de los litorales de Guerrero y Oaxaca, México Littoral tanaidaceans (Crustacea: Peracarida) from Guerrero and Oaxaca, Mexico

open access: yesRevista Mexicana de Biodiversidad, 2010
Los tanaidáceos son componentes esenciales de las cadenas tróficas del bentos marino, son fuente de alimento para especies de relevancia comercial y para otros organismos marinos. A pesar de su importancia, el conocimiento del grupo se ha rezagado debido

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

open access: yesMolecular 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

open access: yesJournal 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

open access: yesBiological 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.

Depth and latitudinal gradients of diversity in seamount benthic communities

open access: yesJournal of Biogeography, Volume 49, Issue 5, Page 904-915, May 2022., 2022
Abstract Aim Latitudinal and bathymetric species diversity gradients in the deep sea have been identified, but studies have rarely considered these gradients across hard substratum habitats, such as seamount and oceanic island margins. This study aimed to identify whether the current understanding of latitudinal and bathymetric gradients in α‐diversity

7.2: Taxon Group: Crustacea - Peracarida v1

open access: yes, 2023
This is part of the collection "DToL Taxon-specific Standard Operating Procedures (SOPs) for Marine Metazoa", lead by the Other Metazoa Working Group. The SOP collection contains guidance on how to process the various marine Metazoa species within the scope of the Darwin Tree of Life project.

The urosome of the Pan- and Peracarida [PDF]

open access: yesContributions 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.

Recent speciation and hybridization in Icelandic deep‐sea isopods: An integrative approach using genomics and proteomics

open access: yesMolecular Ecology, Volume 31, Issue 1, Page 313-330, January 2022., 2022
Abstract The crustacean marine isopod species Haploniscus bicuspis (Sars, 1877) shows circum‐Icelandic distribution in a wide range of environmental conditions and along well‐known geographic barriers, such as the Greenland‐Iceland‐Faroe (GIF) Ridge. We wanted to explore population genetics, phylogeography and cryptic speciation as well as investigate ...

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

open access: yesJournal 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 ...
