Experiment on sensitivities of the macroalgal Fucus vesiculosus germlings to ocean warming, ocean acidification, nutrient enrichment and hypoxia: survival and growth ...

Paired (male and female) Fucus vesiculosus from Kiel Bight were made to release gametes which after fertilization were allowed to settle onto sand-stone cubes. The offspring of one parental pair represented a "sibling group". Replicates of each sibling groups were distributed among the var...

Description
Summary:Paired (male and female) Fucus vesiculosus from Kiel Bight were made to release gametes which after fertilization were allowed to settle onto sand-stone cubes. The offspring of one parental pair represented a "sibling group". Replicates of each sibling groups were distributed among the various treatments in the Kiel Outdoor Benthocosms (KOB, Wahl et al. 2015). As fitness proxies we measured (i) growth and (ii) survival of the germlings. The independent treatments were ocean warming OW (delta of 5°C over ambient conditions), ocean acidification OA (delta of 700 µatm CO2 over ambient condition), combined OAW, nutrient addition (double than ambient) or hypoxia associated with a provoked upwelling of deep water). Sensitivity was quantified for each replicate of a given sibling group as Log Response Ratio of the metric (survival, growth) under a given treatment relative to the same metric under ambient conditions. The experiment ran intermittently from spring 2013 to autumn 2014. ... : Kiel Outdoor BenthocosmsTreatments:OA: delta of 700 µatm CO2 over ambient conditionOW: delta of 5°C over ambient conditionsOAW: combination of OA and OWNutrients: double than ambientHypoxia ...
