The Caprellidae (Crustacea: Amphipoda) of shallow waters of the Caribbean coast of Colombia, South America, are investigated. This is the first study dealing with the caprellidean fauna of this area. A total of 45 stations from Punta Brava to Punta Cañaveral, at Santa Marta region, Colombia, was selected, and samples of algae, coral rubble, sponges, hydroids, bryozoans and sediments were collected from the intertidal zone to 30 m depth. Ten species in seven genera were found (three of which are new to science): Aciconula sp., Caprella cf. penantis Leach, 1814, Caprella danilevskii Czerniavskii, 1868, Deutella caribensis n.sp., D. incerta (Mayer, 1903), D. mayeri Stebbing, 1895, Hemiaegina minuta Mayer, 1890, Paracaprella pusilla Mayer, 1890, Pseudaeginella... |

La fauna de crustáceos malacostráceos limnéticos, en el territorio de Chile continental, está compuesta por seis especies de camarones, i.e., cinco parastácidos de los géneros Parastacus, Samastacus y Virilastacus y un palemónido del género Cryphiops, 18 especies de anomuros del género Aegla, siete especies de anfípodos gamarídeos del género Hyallela y una especie de isópodo aselotano del género Heterias. La distribución conjunta abarca desde Arica a Punta Arenas, pero la mayor parte de las especies tiene rango geográfico restringido. La mayor densidad de taxa ocurre entre las regiones VIII y X, donde el número de taxa por Región varía entre 11 y 15, siendo la X Región la que tiene el número mayor. Índices derivados de un estudio sobre relaciones... |

Los crustáceos peracáridos comprenden un diverso grupo de invertebrados, comunes en ambientes terrestres, acuáticos dulceacuícolas y marinos. En este trabajo se revisa la diversidad de especies de los órdenes Amphipoda, Cumacea, Isopoda, y Tanaidacea, actualmente reportada para Chile. Otros grupos taxonómicos comúnmente incluidos en Peracarida no han sido citados aún para Chile. Presentamos en este trabajo una lista sistemática de los taxa de peracáridos y su distribución geográfica en Chile desde los 18°S hasta los 56°S, incluyendo el Archipiélago de Juan Fernández e Isla de Pascua. En un análisis preliminar, la distribución de las especies registradas para Chile sugiere que la diversidad de especies aumenta de norte a sur. El hecho que aún existen... |

Because of the unique conditions that exist around the Antarctic continent, Southern Ocean (SO) ecosystems are very susceptible to the growing impact of global climate change and other anthropogenic influences. Consequently, there is an urgent need to understand how SO marine life will cope with expected future changes in the environment. Studies of Antarctic organisms have shown that individual species and higher taxa display different degrees of sensitivity to environmental shifts, making it difficult to predict overall community or ecosystem responses. This emphasizes the need for an improved understanding of the Antarctic benthic ecosystem response to global climate change using a multitaxon approach with consideration of different levels of biological... |

The present monograph includes general systematic considerations on the family Epimeriidae, a revision of the genus Epimeria Costa in Hope, 1851 in the Southern Ocean, and a shorter account on putatively related eusiroid taxa occurring in Antarctic and sub-Antarctic seas. The former epimeriid genera Actinacanthus Stebbing, 1888 and Paramphithoe Bruzelius, 1859 are transferred to other families, respectively to the Acanthonotozomellidae Coleman & J.L. Barnard, 1991 and the herein re-established Paramphithoidae G.O. Sars, 1883, so that only Epimeria and Uschakoviella Gurjanova, 1955 are retained within the Epimeriidae Boeck, 1871. The genera Apherusa Walker, 1891 and Halirages Boeck, 1891, which are phylogenetically close to Paramphithoe, are also... |

Interessante waarnemingen van epizoïsche kreeftachtigen op zeezoogdieren langs de Nederlandse kust (Cirripedia, Amphipoda) In de tweede helft van 2003 spoelden twee juveniele bultruggen Megaptera novaeangliae (Borowski, 1781) aan op de Nederlands kust, de eerste op 7 oktober op de Maasvlakte net ten zuiden van de ingang tot de haven van Rotterdam, de tweede op 20 december nabij Katwijk, Zuid Holland. Deze soort was nog niet eerder gemeld van de Nederlandse kust. Op de bultruggen werden vier soorten kreeftachtigen gevonden: Conchoderma auritum, Coronula diadema, C. reginae en Cyamus boopis. De laatste drie soorten zijn nieuw voor de Nederlandse fauna. Exemplaren van de parasieten zijn opgenomen in de collectie van het Nationaal Natuurhistorisch... |

New and lesser-known amphipods of hard substrates in the Delta area of the Netherlands (Crustacea: Amphipoda: Gammaridea) The distribution of 27 new and lesser-known amphipod species of sublittoral hard substrates in the Delta area in the southwest of The Netherlands is described. Data from literature on these species are scarce and/or not readily available. They are supplemented with results from recent investigations of mainly sublittoral hard substrates. Of the 22 marine species only nine occur offshore as well as inshore. The others seem to be restricted to inshore man-made coastline protections. This probably reflects the scarcity of hard substrates further offshore. Four invasive species were recorded in the brackish and freshwater part of the Delta... |

The amphipod Echinogammarus stoerensis not extinct in The Netherlands (Crustacea: Amphipoda: Gammaridea) The gammaridean amphipod Echinogammarus stoerensis has never been a common species in the Netherlands, due to the scarcity of suitable habitats. It is typically found under boulders on a gravelly substrate, where a freshwater flow occurs over the littoral zone. As a result of reinforcement of sea dykes, the typical habitat disappeared from The Netherlands. However, E. stoerensis proves to survive in less suited substrates with more silt, and freshwater supply only from rain. |

The amphipod family Stenothoidae contains more than 200 species in about 40 genera; these genera are at present often defined not by the presence, but by the absence of synapomorphies, thus defining grades rather than clades. Our phylogenetic analyses yielded 4 groups of stenothoids: a basic proboloidid clade; an advanced and always clearly separated Austral-Antarctic thaumatelsonid clade, with a possibly related Arctic mesometopid clade; and finally a poorly resolved group, the stenothoids sensu stricto, including the large and probably polyphyletic genera Stenothoe and Metopa, each with more than 50 species. It is proposed to study and analyse these groups separately in future, based on better redescriptions of the individual species. Our analyses... |

Interspecific interactions between surface and subterranean species may be a key determinant for species distributions. Until now, the existence of competition (including predation) between these groups has not been tested. To assess the coexistence and potential role of interspecific interactions between surface Gammarus fossarum and subterranean Niphargus timavi, and to determine their micro distributions, we conducted a series of field and laboratory observations. We aimed to determine: (1) species substrate preference, (2) whether the presence of G. fossarum influences the habitat choice of N. timavi, and (3) possible predation effects on micro habitat choice of small juveniles. Throughout a small river in SW Slovenia, N. timavi was predominantly found... |
