First record of <i>Synidotea laevidorsalis</i> (Miers, 1881) (Crustacea: Isopoda) in Europe (Gironde estuary, France) OMA
Mees, J.; Fockedey, N..
This note reports on the presence of a well established population of the isopod <i>Synidotea laevidorsalis</i> (Miers) in the Gironde estuary (southwestern France). This species is new for the European fauna. <i>S. laevidorsalis</i> is a nonendemic cool-temperate to subtropical, shallow-water species which was probably introduced into the study area from Asia. In the salinity range of 1 to 10 g l<sup>-1</sup> of the Gironde the species constitutes an important component of the brackish-water hyperbenthic community. The population was already present in 1975 when it was misidentified as the native species <i>Idotea emarginata</i> (Fabricius).

Aberrant individuals of <i>Neomysis integer</i> and other Mysidacea: intersexuality and variable telson morphology OMA
Mees, J.; Fockedey, N.; Dewicke, A.; Janssen, C.R.; Sorbe, J.-C..
Intersexuality in the mysid <i>Neomysis integer</i> is described from samples collected in the Elbe (north Germany), Eems-Dollard (north Netherlands), Westerschelde (south-west Netherlands) and Gironde (south-west France) estuaries. Individuals which had an irregularly shaped or nearly symmetrically rounded telson, rather than a typically truncated one, were also recorded from the four populations studied. A culture experiment with damaged specimens revealed that all types of abnormal telson morphology found in the field can result from regeneration of damaged parts. It is concluded that both intersexuality and aberrant telson morphology are widespread phenomena among estuarine <i>N. integer</i> populations. Both abnormalities seem...

Comparative study of the hyperbenthos of three European estuaries OMA
Mees, J.; Fockedey, N.; Hamerlynck, O..
The hyperbenthic fauna of the subtidal channels of the Eems (N. Netherlands), Westerschelde (S.W. Netherlands), and Gironde (S.W. France) estuaries was sampled within a 15-day period in summer 1991. In each estuary, quantitative samples were taken at regularly spaced stations covering the entire salinity gradient from marine conditions at the mouth to nearly freshwater conditions upstream. The diversity of the samples and the distribution of the species along the main estuarine gradients were assessed. Hyperbenthic communities were identified using different multivariate statistical techniques. The species composition and the density and biomass of the dominant species of each community were compared among communities.

Feeding of the hyperbenthic mysid <i>Neomysis integer</i> in the maximum turbidity zone of the Elbe, Westerschelde and Gironde estuaries OMA
Fockedey, N.; Mees, J..
The diet of the mysid <i>Neomysis integer</i>in the maximum turbidity zone (MTZ) of three European estuaries (Elbe, Westerschelde and Gironde) was investigated in spring 1993. The quality and quantity of the diet were assessed through measurement of the stomach fullness and microscopical analysis of the stomach content combined with image analyses. <i>N. integer</i> was found to be an omnivore which mainly utilizes mesozooplankton and detritus carbon pools. The quality of the diet did not differ between the sexes or between different developmental stages, although smaller individuals consumed fewer items. In all three estuaries the diet was dominated by Copepoda Calanoida (5-10 <i>Eurytemora affinis</i>...
