7 p, 1.1 MB Gephyrocapsa huxleyi ( Emiliania huxleyi ) as a model system for coccolithophore biology / Wheeler, Glen (The Marine Biological Association of the United Kingdom) ; Sturm, Daniela (School of Ocean and Earth Science University of Southampton Southampton UK) ; Langer, Gerald (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Coccolithophores are the most abundant calcifying organisms in modern oceans and are important primary producers in many marine ecosystems. Their ability to generate a cellular covering of calcium carbonate plates (coccoliths) plays a major role in marine biogeochemistry and the global carbon cycle. [...]

5 p, 522.5 KB Novel combination coccospheres from Helicosphaera spp indicate complex relationships between species / Sturm, Daniela (The Marine Biological Association of the United Kingdom) ; Langer, Gerald (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Wheeler, Glen (The Marine Biological Association of the United Kingdom)
Coccolithophores play an important role in global biogeochemical cycling, but many aspects of their ecology remain poorly understood, including their heteromorphic haplo-diplontic life cycle. The presence of combination coccospheres in environmental samples, which represent a transition between the lightly calcified haploid (HOL) and heavily calcified diploid (HET) life phases, provides crucial evidence linking the two life cycle phases of a particular species.

16 p, 1.6 MB Nutritional response of a coccolithophore to changing pH and temperature / Johnson, R. (Universitat Autònoma de Barcelona.

Department of Biological and Environmental Sciences and Technologies) ; Ziveri, Patrizia (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Coccolithophores are a calcifying unicellular phytoplankton group that are at the base of the marine food web, and their lipid content provides a source of energy to consumers. Coccolithophores are vulnerable to ocean acidification and warming, therefore it is critical to establish the effects of climate change on these significant marine primary producers, and determine potential consequences that these changes can have on their consumers.

18 p, 2.2 MB Temperature effects on sinking velocity of different Emiliania huxleyi strains / Rosas Navarro, Anaid (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Langer, Gerald (The Marine Biological Association of the United Kingdom) ; Ziveri, Patrizia (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
The sinking properties of three strains of Emiliania huxleyi in response to temperature changes were examined. We used a recently proposed approach to calculate sinking velocities from coccosphere architecture, which has the advantage to be applicable not only to culture samples, but also to field samples including fossil material.

(Alfred-Wegener-Institut für Polar- und Meeresforschung) ; Langer, Gerald (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
The oxygen isotopic composition (δ18¦O) of calcium carbonate of planktonic calcifying organisms is a key tool for reconstructing both past seawater temperature and salinity. The calibration of paloeceanographic proxies relies in general on empirical relationships derived from field experiments on extant species. [...]
