Nutrient CyclingonCoral ReefsCoralReefsCoralreefsare found in clear tropical waters, making them main attractions for tourists in many tropical regions. The clear water, however, is indicative of an oligotrophic, ornutrientpoor, habitat. The existence of so much life innutrientpoor waters was considered a paradox (known as Darwin's…
Coral reefwaters are generally very low innutrients, yet benthic productivity is among the highest in the world. A general concern ofreefecologists has been to identify the sources ofnutrientsforreefproductivity and the processes responsible fornutrientrecycling onreefs. One potentially important process that has been poorly studied is the recycling of regeneratednutrientsfrom ...
Jan 26, 2021 ·Here, we show that heat stress destabilizes thenutrientcyclingbetween corals and their endosymbiotic algae long before bleaching becomes apparent. Notably, increased metabolic energy demands shift thecoral–algal symbiosis from a nitrogen- to a carbon-limited state, reducing translocation and recycling of photosynthetic carbon.
May 30, 2025 ·Coralreefsreceive both passive and activenutrientsubsidies, supplied via oceanographic processes and animal-mediated transfer, which can bolsterreefproductivity and resilience to disturbance. We examined the relative importance of these two pathways across lagoonal and seawardreefs,reefsof different depths, and those around islands either with or without breeding seabird colonies ...
Such details provide a deeper understanding and appreciation for Nutrient Cycling In Coral Reefs.
May 26, 2023 ·Since nitrogen is the critical limitingnutrientin oligotrophic sunlit ocean (Falkowski, 1997; Moore et al., 2013), understanding the supply, availability, andcyclingof nitrogenin coralholobionts andcoralreefsis essential to resolve the Darwin’s paradox and to predict the future ofcoral reefsystems under global change.
