High rates of carbon and dinitrogen fixation suggest a critical role of benthic pioneer communities in the energy and nutrient dynamics of coral reefs

Nils Rädecker, Hal Hunt Jones II

Following coral mortality in tropical reefs, pioneer communities dominated by filamentous and crustose algae efficiently colonize substrates previously occupied by coral tissue. This phenomenon is particularly common after mass coral mortality following ...

Effect of temperature and feeding on carbon budgets and O2 dynamics in Pocillopora damicornis

Niclas Heidelberg Lyndby, Michael Kühl

Studying carbon dynamics in the coral holobiont provides essential knowledge of nutritional strategies and is thus central to understanding coral ecophysiology. In this study, we assessed the carbon budget in Pocillopora damicornis (usingH13CO3) as a funct ...

In situ eutrophication stimulates dinitrogen fixation, denitrification, and productivity in Red Sea coral reefs

Nils Rädecker, Hal Hunt Jones II

Eutrophication (i.e. the increase of [in-]organic nutrients) may affect the functioning of coral reefs, but knowledge about the effects on nitrogen (N) cycling and its relationship to productivity within benthic reef communities is scarce. Thus, we investi ...

Standardized short‐term acute heat stress assays resolve historical differences in coral thermotolerance across microhabitat reef sites

Nils Rädecker, Gabriela Hannah Holligan Perna

coral thermotolerance differences reflective of in situ reef temperature thresholds. Using a suite of physiological parameters (photosynthetic efficiency, coral whitening, chlorophyll a , host protein, algal symbiont counts, and algal type association), we ...

Simultaneous Measurements of Dinitrogen Fixation and Denitrification Associated With Coral Reef Substrates: Advantages and Limitations of a Combined Acetylene Assay

Nils Rädecker, Hal Hunt Jones II

Nitrogen (N) cycling in coral reefs is of key importance for these oligotrophic ecosystems, but knowledge about its pathways is limited. While dinitrogen (N2) fixation is comparably well studied, the counteracting denitrification pathway is under-investiga ...

Bio-optical properties and radiative energy budgets in fed and unfed scleractinian corals (Pocillopora sp.) during thermal bleaching

Niclas Heidelberg Lyndby, Michael Kühl

Corals live in symbiosis with algal dinoflagellates, which can achieve outstanding photosynthetic energy efficiencies in hospite approaching theoretical limits. However, how such photosynthetic efficiency varies with environmental stress remains poorly kno ...

Copper impact on Red Sea Stylophora Pistillata and investigations on multi-xenobiotic resistance activity

Despite incredible thermotolerance to global warming, corals from Gulf of Aqaba are impacted by other local stressors such as copper (Cu) pollution. Multixenobiotic resistance (MXR) is the first line of cells defense against pollutant, however knowledge on ...

Elevated CO2 Leads to Enhanced Photosynthesis but Decreased Growth in Early Life Stages of Reef Building Coralline Algae

Niclas Heidelberg Lyndby, Michael Kühl

Crustose coralline algae (CCA) are key organisms in coral reef ecosystems, where they contribute to reef building and substrate stabilization. While ocean acidification due to increasing CO2 can affect the biology, physiology and ecology of fully developed ...

Role of photosymbiosis in the Late Triassic expansion of shallow-water Scleractinia

Anders Meibom

Since their appearance in the Anisian (ca. 240 Ma) scleractinian corals rapidly diversified and expandedacross shallow marine environments, becoming the main builders of reefs. This ecological success coralsowe to their symbiotic relationship with photosyn ...

Rapid Recruitment of Symbiotic Algae into Developing Scleractinian Coral Tissues

Thomas Bockel

While the early acquisition of Symbiodiniaceae algae into coral host tissues has been extensively studied, the dynamics of the migration of algal cells into rapidly expanding coral tissues still lacks a systematic study. This work examined two Red Sea bran ...
