Vor einem Tag · Water temperature changes can seriously affect various aspects of coral life, especially those related to their physiology and ecology. Here are a few key processes that can be impacted: Photosynthesis: The symbiotic algae in coral tissues, which provide most of the needed energy through photosynthesis, can be disrupted by temperature changes ...
Vor einem Tag · Coral reefs provide food, protection and habitation for marine lives which coral bleaching posed greater threat on the marine biodiversity. Coral bleaching is basically defined as the physiological stress response between the breakdown of coral- algae relations. The coral has tiny microscopic algae living inside its tissue and depend on each other for survival it is called symbiotic relations ...
11. Mai 2024 · Coral reef, ridge or hummock formed in shallow ocean areas by algae and the calcareous skeletons of coral polyps and other coelenterates. A coral reef may grow into a permanent coral island. Often called ‘rainforests of the sea,’ coral reefs are home to a spectacular variety of organisms.

Vor 3 Tagen · Researchers studied samples from corals, sea urchins, and mollusks, at edges where mineral precursors—temporary building blocks—start to form the new shell or skeleton. There, they found a surprise: corals and mollusks produced a mineral precursor that had never been observed before in living organisms or rocks, and had only recently been created synthetically.
Vor 5 Tagen · Coral skeletons are biocomposites (mineral + organics) of calcium carbonate, in the form of calcite or aragonite. In scleractinian corals, "centers of calcification" and fibers are clearly distinct structures differing with respect to both morphology and chemical compositions of the crystalline units.
Vor 5 Tagen · Downregulation of skeletal isolation processes combined with the fast growth rate of the fungal populations typically causes an event where the fungi finally reach the coral’s soft tissue and begin to invade. Fungal hyphae colonize the coral, ripping their way through soft tissue layers and siphoning core nutrients from the primary system. If there is not already a dysbiotic event occurring ...
