Zooxanthellae (/ ˌ z oʊ ə z æ n ˈ θ ɛ l iː /; sg. zooxanthella) is a colloquial term for single-celled dinoflagellates that are able to live in symbiosis with diverse marine invertebrates including demosponges, corals, jellyfish, and nudibranchs.
Heuchera (/ ˈ h juː k ɪ r ə / HEW-kih-rə [2] or / ˈ h ɔɪ k ə r ə / HOY-kih-rə [3]) is a genus of largely evergreen [4] perennial plants in the family Saxifragaceae. All species are native to North America except for Heuchera sichotensis, native to the Russian Far East. [5] Common names include alumroot and coral bells. [6]
Coral can survive short-term disturbances, but if the conditions that lead to the expulsion of the zooxanthellae persist, the coral's chances of survival diminish. In order to recover from bleaching, the zooxanthellae have to re-enter the tissues of the coral polyps and restart photosynthesis to sustain the coral as a whole and the ecosystem ...
Coral bleaching is the result of the loss of vital zooxanthellae; any of the stressors can cause bleaching. [14] The corals expel their symbionts because they are trying to get rid of any foreign bodies that might be causing them stress. Corals can survive up to a week without the zooxanthellae, but it is difficult. [15]
There is a symbiotic relationship between coral polyps and the photosynthesising algae called zooxanthellae, without which, neither would survive. When sea surface temperatures exceed approximately 29 °C or more, even for a couple of days, the relationship between the coral and its zooxanthellae becomes unbalanced. [ 5 ]
If sea water temperatures rise, conditions may becomes stressful for the corals, and they may expel their zooxanthellae. This process is known as coral bleaching as, without their symbionts, the corals are white. [2] Durusdinium trenchii is a stress-tolerant species, a generalist able to form mutualistic relationships with many species of coral ...
Heuchera maxima is a species of flowering plant in the saxifrage family, known by the common names island alum root, Channel Islands coral bells, and Jill of the rocks. It is endemic to the four northern Channel Islands of California, within Channel Islands National Park. It grows on canyon cliffs in coastal sage scrub habitats. [1]
Heucherellas take their brilliant foliage colors from the Heuchera parents and the dark leaf patterns and cut-leaf shapes from the Tiarella parents. They are often called by their botanical name × Heucherella, but the common name in the USA is "foamy bells" because the common names of the parent plants are "coral bells", and "foam flower" respectively.
