The macrofauna and its distribution in the sheltered, rocky intertidal zone of Helgoland (North Sea) was studied at 9 vertically and/or morphologically different stations from March to September in 1984. Seasonal variations in the communities were described based on each species' “conspicuousness”. A total of 172 species was found. The macrofauna shows a zoned pattern, but also the different substrata, for example, affect its distribution. The number of species increases from the upper… Expand
The macrofauna and macroflora associated withLaminaria digitata andL. hyperborea at the island of Helgoland (German Bight, North Sea)
TLDR
The macroflora and macrofauna associated with two bull kelp species, Laminaria hyperborea and L. digitata, at the island of Helgoland, North Sea are described, showing an association of encrusting bryozoan and hydrozoan colonies. Expand
Community composition of the rocky intertidal at Helgoland (German Bight, North Sea)
At the rocky island of Helgoland (North Sea), the distribution and abundances of intertidal communities were assessed and the effects of wave exposure and tidal height on the spatial distributionExpand
Seasonal occurrence and abundance of caridean shrimp larvae at Helgoland, German Bight
TLDR
Plankton samples were collected from January 1985 to January 1986 to study seasonal occurrence and abundance of caridean shrimp larvae and C. allmanni was observed to have the highest density of all species with approximately 8 larvae per m3. Expand
The macrofauna of a stony sand area in the German Bight (North Sea)
The sublittoral macrofauna of the Steingrund, a stony area east-northeast of Helgoland, was investigated from May till October 1991 using a van Veen grab and a small dredge. The diverse endo- andExpand
The rocky intertidal biotopes of Helgoland: present and past
TLDR
The presence of 4 intertidal biotopes (20%) considered rare or scarce in Britain supports the recognition of Helgoland as a site of special conservation in a regional and international context. Expand
Decapod fauna of the Helgoland trench (Crustacea) a long-term study in a biodiversity hotspot
Thirty-seven species of decapod Crustaceans were collected from the Helgoland Trench during a long-term study through the periods 1982-1992 and 2000-2013. This brings up the decapod species knownExpand
Changes in the macrozoobenthos of the intertidal zone at Helgoland (German Bight, North Sea): a survey of 1984 repeated in 2002
TLDR
Range-related community shifts, introductions of non-indigenous species and the input of pollutants, are considered to explain long-term ecological changes in the invertebrate community at Helgoland. Expand
Larvae of uncommon caridean decapods in the German Bight: Species composition, distribution and abundance
TLDR
It is concluded that developmental stages of ten non-crangonid species, as well as representatives of Palaemonidae, can be expected to occur in the plankton of the German Bight. Expand
Biological interactions and their role in community structure in the rocky intertidal of Helgoland (German Bight, North Sea)

TLDR
The community organization and maintenance in the mid and lower intertidal is influenced to a high degree by biological interactions, whereas both the relatively important herbivory by L. littorea and competition for space between mussels and macroalgae dominate in theMid intert tidal, predation reaches its highest relative degree of importance for community structure in the lower interTidal.

Long-term changes in the macrozoobenthos around the rocky island of Helgoland (German Bight, North Sea)
TLDR
The paper briefly summarizes what is known about long-term changes in the macrozoobenthos of intertidal and subtidal hard-bottom communities around the island of Helgoland and considers southern species which may be considered as indicators of a warming trend. Expand

Algal Zonation in the New England Rocky Intertidal Community: An Experimental Analysis
TLDR
Experimental investigations of the factors affecting zonation of macroscopic, benthic algae in the New England rocky intertidal region demonstrated that biological factors set the lower limits of these plants, and it is suggested that biogeographic ranges of some species may be similarly affected by biotic factors.
