Sentences with phrase «of zooxanthellae»

The loss of zooxanthellae makes the white calcium carbonate coral skeleton visible through the transparent tissue, making the coral appear bright white or «bleached».

The aforementioned research group demonstrated that the expulsion of zooxanthellae at 27 °C (non-thermal stress conditions) is part of a regulatory mechanism that maintains zooxanthellal density and a stable carbon concentration with expulsion of digested or normal forms of symbionts.

Studies have revealed that the different clades of zooxanthellae have different susceptibilities to thermal and light stress.

«We should know about the density of the zooxanthellae within six weeks,» says Andrew Steven, a researcher from the reef authority.

«What are mechanisms of zooxanthella expulsion from coral?.»

«shuffling» — changes in the relative abundance of zooxanthellae clades that are already present in the coral tissue

ref The selective exchange of zooxanthellae is a potential mechanism by which corals might survive climate stressors, such as increased sea temperatures.

They found that many corals died immediately from the heat stress, but others died more slowly following the depletion of their zooxanthellae — the yellowish brown symbiotic algae that live within most reef - building corals.

The tentacles are pronounced and frilly and contain thousands of zooxanthellae.

Also, because any visible bleaching probably indicated a loss of most of the zooxanthellae originally present [46], it was appropriate to include any degree of bleaching, from pale and partially bleached to fully bleached colonies, as an indicator of significant stress in the corals.

These researchers consider that this loss of zooxanthellae and the accumulation of damaged cells results in coral bleaching.

The loss of these zooxanthellae is what we refer to as «coral bleaching».
