Núñez-Pons, complete loss and degradation of those species

Núñez-Pons, L., Bertocci, I. and Baghdasarian, G. (2017).
Symbiont dynamics during thermal acclimation using cnidarian-dinoflagellate
model holobionts. Marine Environmental Research, 130, pp.303-314.

http://www.sciencedirect.com.plymouth.idm.oclc.org/science/article/pii/S0141113617301642?via%3DihubLooking at a Genus of Anemone, Exaiptasia,
the study investigates the anemones response to external heat stimuli, through
both GTS (Gradual Thermal Stress) and HS (Heat Shock).While doing so, chlorophyll and
symbiont dynamics are monitored, in an attempt to test phenomenon known as
phenotypic plasticity (which is when a given genotype may develop different
states of a character or a groups of characters in different environments) of
the photosynthetic holobionts.The study goes on to show that Exaiptasia
anemones have the capability to adapt to gradually increasing temperatures.This research opens up the
possibility of using this genus as a means to help other marine holobionts cope
with the ever increasing sea temperatures, and, hopefully prevent the complete
loss and degradation of those species that do rely on symbionts.The genus Exaiptasia, and
their respective zooxanthellae symbiont have been used in the study
of photobiology due their manipulability within the laboratory
environment, as well as their ability to live aposymbiotically (algae free).These traits highlight, rather
promisingly, the possibility of using this genus as a means of restoration of
the cnidarian symbiosis, once having been exposed to the extreme conditions
brought about by the warming oceans.The symbiotes of the anemones
increased their chlorophyll concentrations while retaining their densities, which
is presumed in the article to cover the higher metabolic demands of the anemone
during the lower photosynthetic efficiency, with this behaviour having a
significant negative cost to itself.I started looking into the
variety of ways Symbidonium are used by coral, as described in ‘Coral
Reefs in the Microbial Seas’, chapter ‘Global Stressors’. Using Primo, I found
the used resource after searching through a variety of different research. The
article stood out to me as I have previously written an essay exploring coral
reefs in microbial seas, with a large ocus on thermal stress to a corals
ability to maintain its symbiosis with its zooxanthellae.
