Seawater carbonate chemistry and grazing and diet preference in Littorina lit...
Ocean acidification and eutrophication have direct, positive effects on the growth of many marine macroalgae, potentially resulting in macroalgal blooms and shifts in ecosystem... -
Seawater carbonate chemistry and elemental ratios in biogenic marine calcium ...
Elemental ratios in biogenic marine calcium carbonates are widely used in geobiology, environmental science, and paleoenvironmental reconstructions. It is generally accepted... -
Seawater carbonate chemistry and respiration rate of Skagerrak invertebrates ...
Coastal hypoxia is a problem that is predicted to increase rapidly in the future. At the same time, we are facing rising atmospheric CO2 concentrations, which are increasing the... -
Regional adaptation defines sensitivity to future ocean acidification
Physiological responses to temperature are known to be a major determinant of species distributions and can dictate the sensitivity of populations to global warming. In... -
Seawater carbonate chemistry and energy status in the periwinkle Littorina li...
In the future, marine organisms will face the challenge of coping with multiple environmental changes associated with increased levels of atmospheric Pco2, such as ocean warming... -
Seawater carbonate chemistry, calcification and dissolution response, and ske...
Increasing atmospheric pCO2 reduces the saturation state of seawater with respect to the aragonite, high-Mg calcite (Mg/Ca > 0.04), and low-Mg calcite (Mg/Ca < 0.04)... -
Seawater carbonate chemistry and biological processes during experiments with...
Anthropogenic elevation of atmospheric carbon dioxide (pCO2) is making the oceans more acidic, thereby reducing their degree of saturation with respect to calcium carbonate... -
Seawater carbonate chemistry during experiments with Littorina littorea, 2007
We demonstrate that acidified seawater can have indirect biological effects by disrupting the capability of organisms to express induced defences, hence, increasing their... -
Abundance and biomass in Kiel Outdoor Benthocosms at the end of the heat wave...
The experiment consisted of three treatments: 0HW = no heat wave; 1HW = one single summer heat wave; and 3HW = three subsequent heat waves. In all three treatments, working with... -
Zoobenthos and sediments time series at List Reede, Sylt, Germany: pilot samp...
In preparation for a forthcoming monitoring project, a shallow subtidal area in the northern Wadden Sea was studied for macrozoobenthos >1 mm sieve size. Using a Reineck-type... -

Environmental variables Semi-exposed (erosion rates of gypsum blocks reaches 0.14 g/h; de Kluijver, 1991). Mostly relative natural red sandstone; gently sloping substratra;... -
Exp. III: cercarial infectivity in mussels and Exp. IV: susceptibility of acc...
The infectivity of H. elongata cercariae was investigated by counting metacercariae in M. edulis, after a standardized exposure to cercariae acclimated at different temperatures... -
Exp. II: cercarial activity and survival
For cercarial activity and survival infected periwinkles were acclimated for three weeks under the different treatments (n=10 individuals per treatment) and incubated to allow... -
Exp. I: cercarial emergence from periwinkles
Cercarial emergence was assessed by counting all cercariae that emerged from single periwinkles exposed to the different treatments. Periwinkles were collected in Årøsund,... -
Macrozoobenthos mapped in the Königshafen (North Sea) tidal flats in August 1989
The intertidal area of "Königshafen" (4.5 km²) near the Island of Sylt was subdivided in to squares of 100x100 m each (n=450) and every second one was studied for... -
