CAPRELLIDS FROM THE CARIBBEAN COAST OF COLOMBIA, WITH DESCRIPTION OF THREE NEW SPECIES AND A KEY FOR SPECIES IDENTIFICATION Boletín de Investigaciones
Guerra-García,José M.; Krapp-Schickel,Traudl; Müller,Hans G..
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...

Use of the burrowing amphipod Tiburonella viscana as a tool in marine sediments contamination assessment BABT
Abessa,Denis M.S.; Sousa,Eduinety C.P.M.; Rachid,Bauer R.F.; Mastroti,Ricardo R..
The acute toxicity of sediment samples from Santos Estuary was evaluated by using sediment toxicity tests with the burrowing amphipod Tiburonella viscana. Survival of amphipods acclimated for 2 and 15 days was also analyzed. The sensitivity of this species was evaluated by 48h-exposure tests using potassium dichromate (K2Cr2O7) as a reference substance. The sediment samples from Gonzaga Beach, Prainha and Paranapuã Beach were not toxic to T. viscana, whereas the samples collected at Santos Channel and São Vicente Bay were toxic. The acclimation period did not affect survival significantly, in spite of the higher mortality within the 15-day acclimated group. The estimated 48-h LC50 to K2Cr2O7 was 6.029 mg/L (3.27-11.12). Toxicity tests using T. viscana were...

Life Cycle Observations on Amphilocus neapolitanus (Della Valle, 1853) (Crustacea, Amphipoda) Associated with Sargassum cymosum C. Agardh, 1820 in Ubatuba, (SP), Brazil BABT
Leite,Fosca Pedini Pereira.
Day and night densities, reproductive biology and life cycle of Amphilocus neapolitanus (Della Valle, 1853), associated with Sargassum cymosum C. Agardh, 1820, were studied during 13 months. The density of juveniles, males and females was higher in night samples than in day samples. Sex ratio was strongly favorable toward the females. Ovigerous females were present in similar densities in both the periods while the non-ovigerous females were predominant at night. The egg number was not correlated with the size of the females. Breeding occurred throughout the year.

Locked in the icehouse: evolution of an endemic Epimeria (Amphipoda, Crustacea) species flock on the Antarctic shelf ArchiMer
Verheye, Marie L.; Backeljau, Thierry; D'Acoz, Cedric D'Udekem.
The Antarctic shelf’s marine biodiversity has been greatly influenced by the climatic and glacial history of the region. Extreme temperature changes led to the extinction of some lineages, while others adapted and flourished. The amphipod genus Epimeria is an example of the latter, being particularly diverse in the Antarctic region. By reconstructing a time-calibrated phylogeny based on mitochondrial (COI) and nuclear (28S and H3) markers and including Epimeria species from all oceans, this study provides a temporal and geographical framework for the evolution of Antarctic Epimeria. The monophyly of this genus is not supported by Bayesian Inference, as Antarctic and non-Antarctic Epimeria form two distinct well-supported clades, with Antarctic Epimeria...

Possible effects of global environmental changes on Antarctic benthos: a synthesis across five major taxa ArchiMer
Ingels, Jeroen; Vanreusel, Ann; Brandt, Angelika; Catarino, Ana I.; David, Bruno; De Ridder, Chantal; Dubois, Philippe; Gooday, Andrew J.; Martin, Patrick; Pasotti, Francesca; Robert, Henri.
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...

Epimeria of the Southern Ocean with notes on their relatives (Crustacea, Amphipoda, Eusiroidea) ArchiMer
D'Udekem D'Acoz, Cedric; Verheye, Marie L..
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...

Interesting records of whale epizoic crustaceans from the Dutch North Sea coast (Cirripedia, Amphipoda) Naturalis
Holthuis, L.B.; Fransen, C.H.J.M..
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...

Nieuwe en minder bekende vlokreeftjes van sublitorale harde bodems in het Deltagebied (Crustacea: Amphipoda: Gammaridea) Naturalis
Faasse, M.A.; Moorsel, G.W.N.M. van.
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...

Nieuwe vindplaatsen van het in Nederland uitgestorven gewaande vlokreeftje Echinogammarus stoerensis (Crustacea: Amphipoda: Gammaridea) Naturalis
Faasse, M.A..
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.

Cladistic analysis of the family Stenothoidae (Amphipoda, Crustacea) Naturalis
Krapp-Schickel, T.; Koenemann, S..
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...

Coexistence of surface and cave amphipods in an ecotone environment Naturalis
Luštrik, R.; Turjak, M.; Kralj-Fišer, S.; Fišer, C..
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...
