Sentences with phrase «coral symbioses»

«The existence of so many novel coral symbioses thriving in a place that is too warm for most corals,» Todd LaJeunesse, an assistant professor of biology at Penn State, explained, «gives us hope that coral reefs and the ecosystems they support may persist — at least in some places — in the face of global warming.»

A new species of hermit crab, Diogenes heteropsammicola (Crustacea, Decapoda, Anomura, Diogenidae), replaces a mutualistic sipunculan in a walking coral symbiosis.

Small corals of other species sheltering in the shadow of the crab - coral symbiosis were also shielded from corallivore predation.

The fundamental technology they have developed is expected to drive molecular research of the coral - algal symbiosis.

Coral bleaching happens when sea temperatures rise, causing the breakdown of the symbiosis between coral and their zooxanthellae (the microscopic plants which gives coral most of its colour), which can be fatal for the cCoral bleaching happens when sea temperatures rise, causing the breakdown of the symbiosis between coral and their zooxanthellae (the microscopic plants which gives coral most of its colour), which can be fatal for the ccoral and their zooxanthellae (the microscopic plants which gives coral most of its colour), which can be fatal for the ccoral most of its colour), which can be fatal for the coralcoral.

We no longer think of coral as a symbiosis between two organisms, but a symbiosis among three organisms, what we call a holobiont,» Grottoli explained.

This is a multiple - level symbiosis because corals house the entire chloroplast - containing zooxanthellae cells within their tissue.

Corals such as the one depicted below have a symbiosis with multiple single - celled organisms called zooxanthellae.

In the short term, corals with flexible symbioses may shuffle or switch zooxanthellae; and an increase in the abundance of thermally tolerant zooxanthellae strains (such as those of clade D) is expected with an increasing frequency of bleaching conditions.

Corals» sensitivity is a consequence of their evolutionary investment in symbiosis with the dinoflagellate alga, Symbiodinium.

Coral and algae, known as zooxanthellae, work in symbiosis by sharing nutrients.

In 2007 I returned to James Cook Univeristy as a Lecturer in the discpline of Biochemistry, I am now a Associate Professor and head of the Symbiosis Genomics Research Group and a Chief Investigator in the ARC Centre of Excellence for Coral Reef Studies.

His CoralCoE colleague, Bill Leggat, head of the Symbiosis Genomics Research Group, said: «Normally, when bleaching kills corals it is a slow death that progresses steadily when temperatures remain high.

One creature that works in symbiosis with the coral is blue algae.

Corals live in symbiosis with algae, and the two creatures depend on each other for survival.

Bleaching — the response to heat in which coral rejects the algae with which it normally lives in symbiosis — has always happened: research earlier this year suggests it could become five times more frequent, and reefs such as Australia's Great Barrier would have no time to recover.

Coral bleaching is the breakdown of symbiosis between coral animal hosts and their dinoflagellate algae symbionts in response to environmental stCoral bleaching is the breakdown of symbiosis between coral animal hosts and their dinoflagellate algae symbionts in response to environmental stcoral animal hosts and their dinoflagellate algae symbionts in response to environmental stress.

The calcite corals first achieved algal symbiosis and came into being 550 million years ago (you are too young to remember) during the Cambrian era, when atmospheric CO2 concentration was 25 times what it is today.

As one expert wrote, the «flexibility in coral — algal symbiosis is likely to be a principal factor underlying the evolutionary success of these organisms».

But again his arguments evoke criticism from his colleagues who wrote, «flexibility in coral — algal symbiosis is likely to be a principal factor underlying the evolutionary success of these organisms».

Corals may bleach — a breakdown of the symbiosis between the reef - building animal and the microalgae in its tissue — when the seawater warms past a threshold (e.g. temperatures are ~ 1 - 2 deg C warmer than the usual annual maximum for a whole month).
