What is a copepod? These small aquatic crustaceans are very diverse and are the most numerous metazoans in the water community. Copepod habitats range from fresh water to hypersaline conditions, from subterranean caves to water collected in bromeliad leaves or leaf litter on the ground and from streams, rivers, and lakes to the sediment layer in the open ocean. Ecologically the planktonic copepods are important links in the aquatic food chain linking microscopic algal cells to juvenile fish to whales. Copepods also have the potential to act as control mechanisms for malaria by consuming mosquito larvae, and contrariwise are intermediate hosts of many human and animal parasites. Although they belong to a separate class of crustaceans, Branchiura (commonly referred to as fish lice) are dealt with here along with the Copepoda, since many copepod researchers also study these external parasites of fish and amphibians. Together the Copepoda and Bracnhiura comprise over 250 described families; 2,600 genera and over 21,000 described species (both valid and invalid, including senior and junior synonyms). The bibliographic database was developed and is maintained by staff of the C.B. Wilson Copepod library, and contains all the known literature for copepods and branchiurans. At present over 53,700 bibliographic entries on copepods are in the database. ... [Information of the supplier, modified]
This is a database of systematic literature on the Decapoda, compiled by the Assembling the Tree of Life: Decapoda project. You can search references online, or download the entire library as an Endnote-compatible reference library. In many cases, we are able to make the full text of the papers available as PDF files. The online references search will also give information on PDF availability. ... [Information of the supplier]
PenBase provides comprehensive information about penaeidin properties, function, diversity and nomenclature. PenBase contains a Database section that lists all known penaeidins by subgroup or shrimp species. (...) Antimicrobial peptides are major components of innate immunity that have been conserved in evolution and found in different phyla of the plant and animal kingdom. Antimicrobial peptides are often small cationic molecules widely distributed in the whole living kingdom where they participate to host defence reactions against invading microorganisms. They are known to be involved in the innate immune response of vertebrate, invertebrate and plant species, and they are thought to be essential in organisms which lack adaptive immunity. Penaeidins are members of a family of antimicrobial peptides, originally isolated from the shrimp Litopenaeus vannamei, which present both Gram-positive antibacterial and antifungal activities (Destoumieux et al, 1997). Penaeidins appear to be a family of antimicrobial peptides ubiquitous among penaeid shrimps where they are major actors of the immune response (Bachère et al., 2004). ...

GBIF Evertebrata III stellt ein Teilprojekt (oder sog. "Knoten") der Initiative Global Biodiversity Information Facility (= GBIF) Deutschland dar und erfasst als Teilknoten vor allem die Gruppe der marinen Evertebraten. GBIF hat sich zum Ziel gesetzt, alle Informationen zur biologischen Vielfalt, die in Deutschland verfügbar sind, unter einem Dach zu bündeln und über ihre Einstiegsseiten zu erschließen. Die Webseite verweist vor allem auf die Teilprojekte verschiedener Forschungsinstitute wie z.B. das Forschungsinstitut Senckenberg und zahlreiche Typensammlungen anderer Einrichtungen. ...

Assembling the Tree of Life (AToL) is a large research effort sponsored by the National Science Foundation. Its goal is to reconstruct the evolutionary origins of all living things. This AToL: Decapoda project is aimed at clarifying the evolutionary history of the decapods (both fossil and extant), including the shrimp, crabs, crayfish, and lobsters. Our group is comprised of five principal investigators and a host of other collaborators at multiple institutions across the globe. ... [Information of the supplier]
Crustacea.net is a website which publishes electronic monographs (interactive identification and information retrieval systems) on crustaceans at any taxonomic level. These monographs are prepared using the DELTA system and include illustrated, interactive keys to each group, plus diagnoses, descriptions and illustrations of each taxon in the group. ...

The British Myriapod and Isopod Group (BMIG) aims to promote the study of myriapods (Myriapoda) and isopods (Isopoda; woodlice and water-slaters). As from 2001 the Journal Bulletin of the British Myriapod Group and the Journal Isopoda are combined to become the Bulletin of the British Myriapod and Isopod Group. Tables of contents of all three periodicals are available. Additionally the society produces a newsletter, which is downloadable. Besides this web site gives hinds how to collect woodlice. Checklists of the British Myriapods and Isopods are also provided. The lists of the millipeds (Diplopoda) and isopods are linked with the database of the National Biodiversity Network (NBN) therefore it is possible to map the distribution of these groups. ...

Diese Webseite liefert Informationen über limnische Wirbellose. Die Darstellungen beschränken sich auf Crustacea (Krebstiere) und Gastropoda (Schnecken). Für diese stehen eine Artendatenbank sowie einzelne Artikel zur Verfügung. Einträge in der Artendatenbank geben Auskunft über mehrere Aspekte der Arten (z.B. Morphologie, Ernährung und Verbreitung). In einzelnen Artikeln finden sich weiterführende Informationen (z.B. zur Biologie und Bestimmung). ... [Redaktion vifabio]
On this page you will find photos of several crabs (Brachyura) and other armored animals (land hermit crabs, crayfish, shrimp, mussels, snails, "dragons" and snakes), and especially a lot of information about keeping, sexing and reproduction. The true crabs are sorted by super families, families and genera. As well you get information about the natural habitats. ... [Information of the supplier, modified]
