Application and reassessment of the reduced species list index for macroalgae to assess the ecological status under the Water Framework Directive in the Atlantic coast of Southern Spain
(Elsevier, 2012)According to the Water Framework Directive (WFD) macroalgae are one of the Biological Quality Elements proposed to assess the ecological status of coastal water bodies. In the case of the North East Atlantic coastal shores, ... -
Biochemical composition of temperate and Arctic populations of Saccharina latissima after exposure to increased pCO2 and temperature reveals ecotypic variation
(Springer, 2014)Previous research suggested that the polar and temperate populations of the kelp Saccharina latissima represent different ecotypes. The ecotypic differentiation might also be reflected in their biochemical composition (BC) ... -
Carbon assimilation in upper subtidal macroalgae is determined by an inverse correlation between Rubisco carboxylation efficiency and CO2 concentrating mechanism effectiveness
(Wiley, 2023)Seaweeds have a wide ecophysiological and phylogenetic diversity with species expressing different Rubisco forms that frequently coexist with biophysical CO2 concentrating mechanisms (CCMs), an adaptation that overcomes ... -
Increased CO2 modifies the carbon balance and the photosynthetic yield of two common Arctic brown seaweeds: Desmarestia aculeata and Alaria esculenta
(Springer, 2015-06-05)Ocean acidification affects with special intensity Arctic ecosystems, being marine photosynthetic organisms a primary target, although the consequences of this process in the carbon fluxes of Arctic algae are still unknown. ... -
Increased temperature and CO2 alleviate photoinhibition in Desmarestia anceps: from transcriptomics to carbon utilization
(Oxford University Press, 2017)Ocean acidification and warming are affecting polar regions with particular intensity. Rocky shores of the Antarctic Peninsula are dominated by canopy-forming Desmarestiales. This study investigates the physiological and ... -
Map kinases mediate the response of arctic macroalgae to temperature and uv radiation stress
(2014-04-10)Mitogen-activated protein kinases (MAPKs) are a group of cytoplasmic phosphoproteins that constitute the central core of the signalling network to respond to stress in most organisms. Their role in stress response in micro- ... -
Rubisco carboxylation kinetics and inorganic carbon utilization in polar versus cold-temperate seaweeds
(Oxford University Press, 2019)Despite the high productivity and ecological importance of seaweeds in polar coastal regions, little is known about their carbon utilization mechanisms, especially the kinetics of the CO2-fixing enzyme Rubisco. We analyzed ... -
Screening for New Cosmeceuticals from Brown Algae Fucus vesiculosus with Antioxidant and Photo-Protecting Properties
(IOAP-MPDI, 2022-10-31)Phlorotannins play a role in biological functions to protect the cells against UV and oxidative damage in brown algae. We hypothesized that these compounds can function as photo-protectors and antioxidants in skin care ... -
Seasonal changes in photosynthesis and biochemical composition in Arctic macroalgae undergoing a climatic transition
(2021-11-02)Seasonal physiology of the algal community in Kongsfjorden sublittoral ecosystem is expected to be affected by Global Climate Change. We characterized the photosynthetic performance (by means of chlorophyll a fluorescence, ... -
Seasonal changes in photosynthesis and biochemical composition in Arctic macroalgae undergoing a climatic transition.
(2023)Seasonal physiology of algal community in Kongsfjorden ecosystem is expected to be affected by Global Climate Change. We characterized the photosynthetic performance and biochemical composition of five common macroalgal ... -
Seasonal variation in the biochemical composition of Arctic macroalgae: Effect of warming and photoperiod
(2021-11-02)The effect of temperature and photoperiod along the year on the composition of 5 macroalgal species representative of the sublittoral system of Kongsfjorden was studied in laboratory conditions. These species were the ... -
Short-term effects of CO2, nutrients and temperature on three marine macroalgae under solar radiation.
(Inter-Research, 2014-10-20)Three macroalgal species belonging to Chlorophyta (Ulva rigida), Rhodophyta (Ellisolandia elongata) and Phaeophyceae (Heterokontophyta; Cystoseira tamariscifolia), naturally growing at the same shore level and representing ... -
Warming and Ocean Acidification Effects in the Seaweed Community of West Spitsbergen
(2017-10-02)Global change-related warming and ocean acidification (OA) are major threats to the Svalbard coastal ecosystem. Rock bottom areas are mainly dominated by dense forests of a multi-species community of seaweeds. Different ...
