Effect of increased CO2 and dissolved iron on primary productivity and inorganic carbon uptake during a bloom of the coccolithophore Emiliania huxleyi
Íñiguez Moreno, Concepción; Lorenzo, M. Rosario; Segovia-Azcorra, María
(2014-07-03)
Net primary production (NPP) and inorganic carbon uptake were analysed during a bloom of Emiliania huxleyi in mesocosms. The experiment lasted 25 days and was carried out in the Raunefjord off Bergen (Norway, June 2012) ... -
High-CO2 Levels Rather than Acidification Restrict Emiliania huxleyi Growth and Performance
Vázquez Manzanares, Víctor; León Díaz, Pablo Ignacio; López-Gordillo, Francisco Javier; Jiménez, Carlos; Íñiguez Moreno, Concepción; MacKenzie, Kevin; Bresnan, Eileen; Segovia-Azcorra, María[et al.] (Springer, 2022-05-27)
The coccolithophore Emiliania huxleyi shows a variety of responses to ocean acidification (OA) and to high-CO2 concentrations, but there is still controversy on differentiating between these two factors when using different ... -
Interactive effects of increased CO2 levels and iron availability on the marine pelagic food web during a mesocosm experiment
Segovia-Azcorra, María (2014-07-03)
A mesocosm experiment was carried out in the Raunefjord, off Bergen, Norway (June 2012) to investigate the interactive effects of increased CO2 and iron availability on the pelagic food web. Twelve mesocosms (11m3) covered ... -
Resilience to UV radiation and high PAR in the marine Chlorophyte Dunaliella tertiolecta and the interaction of increased CO2 in the context of global change
(Universidad de Málaga, Servicio de Publicaciones y Divulgación Científica, 2014)UVR is considered a prime factor able to cause detrimental effects on phytoplankton (Vincent & Roy 1993). It is particularly relevant when considering the increase in ultraviolet-B radiation reaching the ocean surface due ... -
Response of the coccolithophore Emiliania huxleyi to increased CO2 and Fe availability within the plankton food web
(UMA Editorial, 2016)Ocean acidification due to increased CO2 emissions derived from anthropogenic activities is affecting marine ecosystems at an unprecedented rate (IPCC 2013). Ocean acidification has the potential to affect the physiological ... -
The effects of ocean acidification and siderophore additions on trace-metal dynamics during an Emiliania Huxleyi- dominated bloom in a coastal mesocosm experiment
Lorenzo, M. Rosario; Maldonado, Maria T.; Lázaro, Francisco J.; Cullen, Jay T.; Segovia-Azcorra, María (2014-07-03)
The combined impacts of high CO2 and changes in trace metal availability on plankton remain largely unknown. A 22 days mesocosm experiment was carried out in the Raunefjord, off Bergen, Norway (June 2012) to investigate ... -
Trace-metaldynamics in response of increase CO<sub>2</sub> and iron availability in a coastal mesocosm experiment
Lorenzo, M. Rosario; Maldonado, Maria T.; Lázaro, Francisco J.; Cullen, Jay T.; Segovia-Azcorra, María (2015-04-14)
A mesocosm experiment was performed in the Raunefjord (Norway) to study changes in dissolved Cu (dCu) and Fe (dFe), and in the elemental composition of particles during an <em>Emiliania huxleyi</em> dominated bloom. The ...
