| The infection of the estuarine teleost fishes Mugil gaimardianus Desmarest, 1831 (Mugilidae), Arius phrygiatus Valenciennes, 1839 (Ariidae), Conodon nobilis Linnaeus, 1759 (Haemulidae), Cetengraulis edentulus Cuvier, 1829 (Engraulidae), and Anableps anableps Linnaeus, 1758 (Anablepidae) by praniza larvae of Gnathiidae (Crustacea, Isopoda) was studied in specimens fished off the Atlantic Ocean in Northeast of Pará State, near Bragança, Brazil. The highest infection prevalence value was found in Anableps anableps (42.3%) and the lowest in Conodon nobilis (9.1%). The mean intensity varied from 1 parasitein Conodon nobilis to 19.5 in Arius phrygiatus. A description of the larvae is provided. The morphology of the mouthparts is related to the blood sucking... |

| 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... |

| Terrestrial isopods of the Ooijpolder: part 1. distribution (Crustacea: Isopoda: Oniscidea) The distributions and habitats of woodlice were investigated in ‘the Ooijpolder’, also named ‘the Ooij’. The area of approximately 41 square kilometers is located along the river Waal, east of Nijmegen, Province of Gelderland, The Netherlands (fig. 2). In total 1464 squares of 100 x 100 m (utm) (fig. 9) were sampled by hand from 1991 up to 1998 (Table 1). On a recording form (fig. 5) five first order habitats were distinguished (Table 2): 1. The river foreland is flooded on average for a few weeks once every winter or spring, and is bounded by a winterdyke. 2. The sandy river dunes in the flood plains are inundated only very occasionally. Three old brickstone... |

| The interstitial crustacean isopods of the genus Microcharon (Microparasellidae) are relatively well-diversified and widely distributed in Morocco. A new species, M. boutini, is described. The 5-dentate mandibular pars incisiva, the elongated inner lobe of the exopodite, and the reduced armature of the first male pleopod characterize the species. M. boutini n. sp. belongs to the monophyletic messoulii group of species, the most primitive representatives of the genus. The distribution of M. boutini n. sp. covers both the northwestern part of the Jbilet and the nearest adjacent plain, as well as the High Atlas of the Marrakech piedmont. From a historical biogeographic point of view, interstitial ancestral marine populations would have been left in... |

| Asellus aquaticus is present in 19 of about 100 Turkish groundwater stations prospected during biospeleological explorations. All specimens of these stygophilic populations remain oculate, even though their integumental pigmentation is more or less reduced. Proasellus lykaonicus Argano & Pesce, 1978 has been found again in a second cave, nearby the type locality. A large and endemic, stygobiont species, Proasellus pisidicus n. sp., from phreatic groundwater, Vilâyet Burdur, and the minute Proasellus pamphylicus n. sp. from interstitial waters of the eastern part of Vilâyet Antalya are described. The stygobiont proasellids of Asia Minor, P. lykaonicus and P. pisidicus n. sp. belong to the same phylogenetic strain of Proasellus as those of Transcaucasia,... |

| Several species of “philosciid” Oniscidea are known from Brazil, most of them were found in the southern and eastern parts of this country. The genera Atlantoscia Ferrara & Taiti, 1981, Benthana Budde-Lund, 1908 and Balloniscus Budde-Lund, 1908, the latter considered to represent a separate family Balloniscidae Vandel, 1963, are considered the only neotropical philosciids bearing respiratory areas on their pleopods. Therefore, representatives of these genera are re-examined to shed new light on the question whether these species can be considered to be a monophylum with the autapomorphy “respiratory areas present”, The phytogeny of the above-mentioned genera is discussed under morphological and biogeographical aspects. Furthermore, a remarkable new... |

| 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... |
