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.

Depth and latitudinal gradients of diversity in seamount benthic communities
Journal 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

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 ...

On the origin and evolution of Antarctic Peracarida (Crustacea, Malacostraca)
Scientia Marina, 1999 The early separation of Gondwana and the subsequent isolation of Antarctica caused a long evolutionary history of its fauna. Both, long environmental stability over millions of years and habitat heterogeneity, due to an abundance of sessile suspension ...
