Sentences with phrase «on zooxanthellae»

If data are available, use physiological studies of dominant corals to assess likely resistance and tolerance based on zooxanthellae type, photo - protective pigments, or tissue condition (lipid levels), and / or heterotrophic capacity.

Not exact matches

This isn't the helpful zooxanthellae algae that sustains the coral, but a different species that actually contests with the corals for real estate on the reefs.

On the other hand, if the stressful conditions prevail, accumulation of the damaged symbiotic zooxanthellae may not maintain the expulsion, which will gradually accumulate in coral tissues.

In this study, we used ribosomal RNA gene sequencing to identify the zooxanthellae, bacteria and archaea associated with healthy and yellow band diseased (YBD) colonies in the Media Luna reef of La Parguera, Puerto Rico, in order to examine the influence of YBD on the Montastraea faveolata microbiome.

Information on abundance of clade D zooxanthellae can help managers understand the susceptibility of specific corals to thermal stress and also to identify changes in coral reef health.

The potential to adapt to increasing sea - surface temperatures depends on the extent of genetic variation for heat tolerance, the generation time of the coral host and zooxanthellae, and the strength of selection.

For kids who love the ocean, there's a fascinating study on cnidarians, zooxanthellae, and coral reef ecosystems.

In an article on Yale 360 Environment, Veron writes that the major issues include mass bleachings caused by warmer water, which kills off zooxanthellae, the algae with which coral have a symbiotic relationship, and ocean acidification.

«Corals live in a symbiotic relationship with zooxanthellae, which are plant - like cells hosted in surface tissues that provide up to 90 % of the energy to the colony,» said Stephen Simpson, a marine biologist at the University of Exeter in the UK, commenting on the study.

Some polyps may be able to obtain enough food on their own and some may be able to obtain new zooxanthellae.

One study found that coral nubbins collected from the same colonies on the Great Barrier Reef (GBR) and pre-exposed to slightly elevated temperatures subsequently experienced less zooxanthellae loss than controls when experimentally bleached [33].

First, it's noteworthy how opinion has solidified on the point that bleaching (corals expelling their associated symbiotic zooxanthellae) is a response to higher temperature driven by general warming of the seas, rather than being due to locally specific causes.
