Seagrass can mitigate negative ocean acidification effects on calcifying algae [PDF]

open access: yes, 2019
The ultimate effect that ocean acidification (OA) and warming will have on the physiology of calcifying algae is still largely uncertain. Responses depend on the complex interactions between seawater chemistry, global/local stressors and species-specific

Calculating the global contribution of coralline algae to carbon burial [PDF]

open access: yes, 2015
The ongoing increase in anthropogenic carbon dioxide (CO2) emissions is changing the global marine environment and is causing warming and acidification of the oceans.

Systematic review and meta-analysis of ocean acidification effects in Halimeda: Implications for algal carbonate production

open access: yesClimate Change Ecology, 2023
Ocean acidification (OA) has been identified as one of the major climate-change related threats, mainly due to its significant impacts on marine calcifiers.

Flora algal de la cuenca del río Guadalquivir: Su valor en la determinación de la ecorregionalización de la cuenca [PDF]

open access: yes, 2018
In compliance with the Water Framework Directive of the European Union, we needed to diagnose the ecologic quality of the different sections of the rivers of the Guadalquivir basin. In order to establish a regional classification of the water bodies by a

Tubular microfossils from ∼2.8 to 2.7Ga-old lacustrine deposits of South Africa: A sign for early origin of eukaryotes? [PDF]

open access: yes, 2016
Unequivocal evidence for Archean eukaryotic life has been long sought for and is a matter of lively debate. In the absence of unambiguous fossils this debate has focused on biogeochemical signatures and molecular phylogenies.

Calcareous algae from Upper Albian - Cenomanian strata of the Potiguar basin (NE Brazil)

open access: yesGeologia Croatica, 2008
Calcareous Albian-Cenomanian strata in the Potiguar basin yield a number of microfossils, among which are calcareous algae (Dasycladales and Corallinales).

The roles of endolithic fungi in bioerosion and disease in marine ecosystems. I. General concepts

open access: yesMycology, 2017
Endolithic true fungi and fungus-like microorganisms penetrate calcareous substrates formed by living organisms, cause significant bioerosion and are involved in diseases of many host animals in marine ecosystems.

Calcareous algae, foraminifera and sequence stratigraphy of the Fahliyan Formation at Kuh-e-Surmeh (Zagros Basin, SW of Iran)

open access: yesGeologia Croatica, 2008
Palaeontological, environmental and sequence stratigraphic studies were carried out on the shallow carbonate platform facies of the Berriasian – Hauterivian, Fahliyan Formation and the lower part of the Gadvan Formation, at Kuh-e-Surmeh. The studies were

The colonization of the oceans by calcifying pelagic algae [PDF]

open access: yesBiogeosciences, 2019
The rise of calcareous nannoplankton in Mesozoic oceans has deeply impacted ocean chemistry and contributed to shaping modern oceans. Nevertheless, the calcareous nannoplankton colonization of past marine environments remains poorly understood.
