Comparison of biodiversity on four different hard substrate types in the intertidal zone in the Wadden Sea on Sylt, Germany (including a species’ list)
Marine intertidal hard substrates provide an ecologically important habitat for many sessile or semi-sessile organisms. As shelter, food source, nursery or living space, they are of central importance in marine ecosy- stems ...
Filtration rates in three different Scandinavian ascidians: quantification of the influence of salinity on feeding efficiency
Ascidians are marine filter-feeding organisms, which feed on phytoplankton and organic detritus. We examined the influence of salinity on absolute and individual filtration rates of three Scandinavian ascidian species ...
Biomassen-Spektrum im Gullmarfjord – Eine Methode, zur Analyse eines strandnahen pelagischen Ökosystems
A useful appliance in the analysis of the structure of ecosystems is seen in the biomass spectra. It allows a general approach to monitor interactions and changes in a biocenosis. As anthropogenic influences conti- nuously ...
Habitat preferences of Pomatoschistus minutus (Gobiidae) under laboratory conditions
Pomatoschistus minutus (Pallas, 1770) is a small camouflaged gobiid fish that lives in the shallow subtidal. While predation has been shown to be important for population structure in sand gobies evidence for active habitat ...
Morphological investigations of selected echinoids
Echinoids have a radial pattern that is formed by sceletal plates which are fused to each other and form rows that run from the oral to the aboral surface. These plates can be divided into ambulacral and interambulacral ...
