The brown shrimp Crangon crangon is an opportunistic feeder that is widely distributed in the Atlantic Ocean. It has a large pray spectrum and uses ambush tactics while hunting. To explore the possibility of memory and ...

In the present study we examined the homing behavior, distribution and locality-preferences of two groups of Gastropods, Patellidae and Trochidae, in the Eulittoral of the rocky shore at Le Cabellou, Brittany/France. By ...

In the Wadden sea of Sylt Littorina littorea constitutes a wide spreaded species of snails. Since L. littorea possesses no defence mechanisms against settling by epibionts such as chemical barricades, the periwinkles are ...

During a survey in September 2010 in Tjärnö, Sweden, we examined differences in the occurrence of the barnacle Semibalanus balanoides at rocky shores. We sought to proof whether there were differences in the density of S. ...

Two deterministic reaction-diffusion models are introduced to simulate a general molecular mechanism, which can produce a variety of different pigmentation patterns on the shells of molluscs. We focused on the reconstruction ...

Between 26.03.06 and 05.04.06 we examined the settlement preferences of the bryozoan Flustrellidra hispida on the brown alga Fucus serratus in the rocky intertidal of Le Cabellou in France. In field experiments we ...

Aktinien gelten als überwiegend sessile Tiere, führen aber durchaus bei Änderung der Umweltbedingungen Bewegungen aus, um ihren Standort zu ändern. Im Felswatt von Concarneau haben wir beobachet, ob Aktinien verschiedener ...

Anthropogenic disturbance is known to be highly influential on ecosystems. Sensitive systems with a high ratio of specialized Fauna and Flora are often more affected than those inhabited with generalists. An example of a ...

The green crab Carcinus maenas is a common littoral crab and belongs to the most invasive species on earth. Due to human transport systems across the oceans, this species had the opportunity to spread worldwide. But for ...

The composition of organisms in the interstitial depends on various abiotic factors of the habitat, e.g. grain size, water content and depth of the oxidationhorizon in the sediment. In this study, we compared the presence ...
