    A comprehensive synthesis of the information available on Isopods within Britain and Ireland (40 species of woodlice & 4 species of waterlice). Presents the results of the Non-marine Isopod Recording Scheme to the end of Species accounts provide details on identification and distribution, habitat and associated species. Phreatoicidean isopods are ancient members of Australia's fauna. In fact, fossil evidence shows that these crustaceans have been living in fresh water longer than Australia has been a separate continent. Phreatoicidean isopods require permanent sources of water, so they are limited to the areas of Australia where water never disappears.

    Asellota is a large taxon of freshwater and marine isopods. The uropods are terminal and biramous. The posterior four abdominal segments and telson are fused to form the pleotelson. The male, and sometimes female, first pereopods are subchelate. A new species of freshwater isopod, Heterias petrensis (Family Janiridae, tribe Asellota) is described. The species is found in Lake Crescent, Tasmania. A revised description is given of Cited by: 2.

    Isopoda is an order of crustaceans that includes woodlice and their relatives. Isopods live in the sea, in fresh water, or on land. All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in s brood their young in a pouch under their : Malacostraca. The Asellidae are a family of isopod crustaceans, one of the largest families of freshwater isopods, living in both epigean and hypogean habitats in North America and Europe. The family includes these genera: [3]Class: Malacostraca.

They have radiated widely, with some re-emerging into shallower water, while others occur in freshwater habitats including caves and Cited by: 6.

Introduction. Isopods are generally small crustaceans, usually with seven pairs of legs that range in size from micrometres (Microcerberidae) to nearly 50 centimetres (Bathynomus).Their name, meaning "like-foot" or similar (iso) and foot (pod), probably comes from early zoologists' familiarity with the common terrestrial "slaters" or "woodlice" (other names: cloportes.

The suborder Phreatoicidea has the largest number of endemic genera.

Other primary freshwater taxa have small numbers of described species, although more species are being discovered, especially in the southern by: About this book.

4 species of waterlice and 40 species of woodlice occur outdoors in Britain and Ireland. A further 12 introduced 'alien' species occur in artificial climates such as glasshouses. This new atlas presents the results of the Non-marine Isopod Recording Scheme to.

The biodiversity of freshwater isopods is derived from my research on the Phreatoicidea and Asellota, and from the online ‘‘World List of Isopoda’’ (Kensley et al., ). The classification is derived from that list (not as in Banerescu, ), but.

Aquatic isopods, like many other freshwater invertebrates, are used for gauging water quality. Biologists conduct censuses of the organisms living in streams. Based on relative numbers of different species, they can determine if pollutants, siltation, and other factors are.

The isopod crustaceans are diverse both morphologically and in described species numbers. Nearly described species (∼9% of all isopods) live in.

The Freshwater Isopods of the Genus Lirceus (Asellota, Asellidae) Leslie Hubricht Main St., Danville, Virginia J. Mackin Texas A & M Research Foundation, Grande Isle, Louisiana In the genus Asellus we have, in the first and second pleopoda of the male, characters which can be relied upon to distinguish the species, but in Lirceus.

Both Isopoda and Mysidacea have numerous freshwater representatives. Isopods (Figure ), sometimes called aquatic sowbugs, comprise about described freshwater species, and almost rival amphipods in diversity, ecological importance, and geographic reach (Wilson, ).Most freshwater isopods are detritivorous, but some are carnivores and scavengers.

INTRODUCTION Although the isopod family, Janiridae, contains a predominance of entirely marine genera, freshwater genera have been described from South Africa (Barnard Asellota is a suborder of isopod crustaceans found in marine and freshwater environments.

Roughly one-quarter of all marine isopods belong to this suborder. Members of this suborder are readily distinguished from other isopods by their complex copulatory : Malacostraca.

Heterais exul, previously known from Brazil and Argentina, was collected from a number of lakes and streams in the Lakes Region of Chile (between Valdivia and Puerto Montt). It was found in a wide variety of habitats: on leaf litter, detritus, algae, rotting wood, emergent vegetation, and clean sandy bottoms.
