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... |

Com o objetivo de elucidar alguns aspectos da biologia reprodutiva de Ligia exotica Roux, 1828, duas populações que habitam o Estuário da Lagoa dos Patos (Molhe Oeste da Barra de Rio Grande e Ilha do Leonídeo) foram analisadas. A amostragem foi realizada quinzenalmente entre o verão/2003 e o inverno/2004. Os animais foram coletados manualmente durante uma hora. O período reprodutivo da espécie foi registrado para os meses de outubro a junho. Nenhuma fêmea ovígera foi observada de julho a setembro. No Molhe Oeste da Barra de Rio Grande, 5.376 indivíduos foram capturados (1.494 juvenis, 1.748 machos e 2.134 fêmeas, das quais 245 eram ovígeras). A proporção sexual estimada foi 0,78 (M:F). Para a análise da fecundidade, 178 fêmeas ovígeras com o marsúpio... |

The mineralized tergite cuticle of four terrestrial isopods (Oniscoidea) (Ligia oceanica, Oniscus asellus, Porcellio scaber and Armadillidium vulgare ) and of the marine isopod Sphaeroma serratum shows a general organization comparable to the fundamental plan of the decapod sclerite cuticle. Moreover, as in decapods, the procuticular layers are not tanned and mineralization rates, from 60 to 80% of the total cuticular dry weight, are of the same importance. However, the chitin protein microfibril distribution according to a homogeneous system in the mineralized procuticular proximal layer in all isopod species so far studied does not allow any comparison of this layer with the non-mineralized membranous layer. |

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... |

Over a 7-year period, parasites have been collected from 28 species of groupers (Serranidae, Epinephelinae) in the waters off New Caledonia Host-parasite and parasite-host lists are provided, with a total of 337 host-parasite combinations, including 146 parasite identifications at the species level Results are included for isopods (5 species), copepods (19) monogeneans (56), digeneans (28), cestodes (12) and nematodes (12) When results are restricted to those 14 fish species for which more than five specimens were examined and to parasites identified at the species level, 109 host-parasite combinations were recorded, with 63 different species, of which monogeneans account for half (32 species), and an average of 4 5 parasite species per fish species... |

Cylisticus convexus, a rare synanthropic woodlouse in The Netherlands (Crustacea: Isopoda: Cylisticidae) Until recently, the occurrence of Cylisticus convexus (De Geer, 1778) in the Netherlands was uncertain. The only certain old record dates from March 1927, when the species was collected at the coal-shed of the Zoological Museum at Amsterdam. During the last years, two specimens have been collected on semi-natural sites. Both were found on a dike, one near Everdingen, in the province of Gelderland, and one near Ritthem, in the province of Zeeland. These are the first records of C. convexus in the field. Yet the species certainly is very rare in The Netherlands. The most important morphological characteristics of the species are described and... |

De provincie Limburg is relatief goed onderzocht op het voorkomen van landpissebedden. De vele onderzoeken hebben in een lijst van 25 soorten geresulteerd, waaronder een aantal dat grotendeels tot deze provincie beperkt is. De brede pissebed komt onder natuurlijke omstandigheden alleen in Zuid-Limburg voor en is in de rest van het land verspreid in tropische kassen en soms in huis aan te treffen. Sinds de oprichting van de EIS-werkgroep Bodemfauna in 1990 werd ze ondanks goed zoeken niet meer vrijlevend in Limburg waargenomen. De laatste waarneming dateerde alweer van 1981. Daar is nu verandering in gekomen. In materiaal verzameld in kalkgraslanden in Zuid-Limburg in de zomer en herfst van 2005 werd P. dilatatus gevonden. Daarna is ze ook op andere... |

During an expedition with RV Victor Hensen (1994) and the RV Polarstern (1996) Isopoda Sphaeromatidae were collected in and off the eastern entrance of the Beagle Channel. The species found, Caecocassidias patagonica Kussakin, 1967, Cassidinopsis emarginata (Guérin-Méneville, 1843) and Moruloidea darwinii (Cunningham, 1871), were previously all poorly or insufficiently described; therefore a redescription is presented herein. Exosphaeroma gigas (Leach, 1818) was also collected frequently, but it was already redescribed earlier and thus only the localities are presented. Moreover, a new species, Cymodopsis beageli, n.sp., which is most closely allied to Cymodopsis sphyracephalata Hurley & Janssen, 1977, is described from the Beagle Channel. |

Three species of Amphipoda are recorded from interstices of a marine beach on the island of Santiago, Cape Verde Archipelago: Cabogidiella littoralis n. gen., n. sp. (Bogidiellidae), Psammogammarus spinosus n. sp. (Melitidae), and Idunella sketi Karaman, 1980 (Liljeborgiidae). The latter, widely distributed species (West Indies, Canary Islands), is new to the Cape Verde Islands. Furthermore, an isopod is described from the same locality, Caecostenetroides mixtum n. sp. (Gnathostenetroididae). |
