Thermal plasticity of Laminaria digitata - seasonal growth; recruitment; ther...
We investigated effects of temperature during ontogeny of the kelp Laminaria digitata across haploid gametophyte and diploid sporophyte life cycle stages in 5 distinct genetic... -
Seawater carbonate chemistry and effects of ocean acidification on different ...
In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Lavigne and Gattuso, 2011) was used to compute a complete and consistent... -
Crustaceans and fish abundances and species at and around artificially introd...
The study area is situated 400 m north of a small rocky island (Helgoland, 54°11'N, 07°52'E) in the southern North Sea. Fish and crustacean abundances were sampled using SCUBA... -

In the coming decades, artificial defence structures will increase in importance worldwide for the protection of coasts against the impacts of global warming. However, the... -
Crustaceans and fish abundances and species at and around artificially introd...
The micro-scale spatial distribution patterns of a demersal fish and decapod crustacean assemblage were assessed in a hard-bottom kelp environment in the southern North Sea.... -
Effects of ocean acidification on different life-cycle stages of the kelp Lam...
Our objective for this study was to evaluate the influence of preindustrial and expected future atmospheric CO2 concentrations (280 µatm and 700 µatm pCO2, respectively) on... -

Historic macrozoobenthos data from Heligoland, 1963 to 1974
Between 1950 and 1974, Erich Ziegelmeier regularly collected macrozoobenthos samples around the Island of Heligoland. Only few of these samples were evaluated (Ziegelmeier 1978)... -
