Caribbean corals of the Montastraea annularis species complex associate with four taxa of symbiotic dinoflagellates (zooxanthellae; genus Symbiodinium) in ecologically predictable patterns. To investigate the resilience of these host-zooxanthella associations, we conducted field experiments in which we experimentally reduced the numbers of zooxanthellae (by transplanting to shallow water or by shading) and then allowed treated corals to recover. When depletion was not extreme, recovering corals… 
Zooxanthellae of the Montastraea annularis Species Complex: Patterns of Distribution of Four Taxa of Symbiodinium on Different Reefs and Across Depths
TLDR
Observed srDNA heterogeneity within samples of Symbiodinium B, C, and E is interpreted as variation across copies within this multigene family, and sequences from natural samples should be interpreted cautiously.
Multiple symbiotic partnerships are common in scleractinian corals, but not in octocorals: Comment on Goulet (2006)
TLDR
It is suggested that the majority of scleractinian coral species, including virtually all of the dominant reef-building taxa, can be found hosting multiple symbiont types, even at the clade level.
The genetic identity of dinoflagellate symbionts in Caribbean octocorals
TLDR
In the Caribbean, octocorals show more symbiont specificity at the cladal level than scleractinian corals, however, both octocarals and sclerACTinianCorals exhibited taxonomic affinity between zooxanthella clade and host suborder.
The effects of Symbiodinium (Pyrrhophyta) identity on growth, survivorship, and thermal tolerance of newly settled coral recruits
TLDR
These findings suggest that light use and carbon acquisition by the coral host are decoupled, but did not distinguish the source of this difference.
Identity and diversity of coral endosymbionts (zooxanthellae) from three Palauan reefs with contrasting bleaching, temperature and shading histories
TLDR
The data indicate that whole coral assemblages, when growing in elevated seawater temperatures and at reduced irradiance, can be composed of colonies associated with the more thermo‐tolerant clade D zooxanthellae, and future increases in seawater temperature might result in an increasing prevalence of Symbiodinium phylotype D in scleractinian corals.
Geographic and habitat partitioning of genetically distinct zooxanthellae (Symbiodinium) in Acropora corals on the Great Barrier Reef
TLDR
The results show that the distribution of genetically distinct zooxanthellae is correlated with light regime and possibly temperature in some (but not all) colonies of A. tenuis and A. valida and at some reef locations, which is interpreted as acclimation to local environmental conditions.
Symbiodinium associations with diseased and healthy scleractinian corals
TLDR
Symbiodinium types are identified using the internal transcribed spacer-2 region of ribosomal DNA from diseased and healthy tissues within individual coral colonies infected with black band disease, dark spot syndrome, white plague disease, or yellow blotch disease in the Florida Keys and the US Virgin Islands, indicating disease resistance and susceptibility in scleractinian corals.
The Occurrence of Mixed Infections of Symbiodinium (Dinoflagellata) within Individual Hosts
TLDR
To examine the distribution of reports of mixed Symbiodinium infections in corals and nonscleractinian hosts from a phylogenetic perspective, it is shown that hosts showing evidence of mixed infection are broadly distributed across the most deeply divergent host lineages, including foraminifera, mollusks, sponges, and cnidarians.
Spatially distinct and regionally endemic Symbiodinium assemblages in the threatened Caribbean reef-building coral Orbicella faveolata
TLDR
This work investigates the geographic and within-colony complexity of Symbiodinium-O.
Pigmentation patterns of Siderastrea stellata Verrill, 1868 (Cnidaria, Scleractinia) from coastal reefs in Northeastern Brazil and its relation with zooxanthellae and other microsymbionts
Changes in the pigmentation patterns of 70 randomly-selected colonies of Siderastrea stellata growing on coastal reefs at Cabo Branco, Paraiba State, Brazil, were examined using photographic records

TLDR
Habitat specificity provides ecological explanations for the previously documented poor concordance between host and symbiont phylogenies and the otherwise surprising lack of direct, maternal transmission of symbionts in many species of hosts.
REVIEW—DIVERSITY AND ECOLOGY OF ZOOXANTHELLAE ON CORAL REEFS
  • R. Rowan
  • Environmental Science, Biology
  • 1998
TLDR
Animal-algal endosymbioses are a dominant feature of coral reefs and an enduring theme in coral reef biology, and recent studies of zooxanthella diversity have sought to establish evolutionary and ecological relationships, both among symbiont and between symbionts and their hosts.
Molecular genetic identification of symbiotic dinoflagellates (zooxanthellae)
TLDR
Molecular genehc methods to zooxanthella taxonomy arehed and small ribosomal subunit RNA (ssRNA) genes can be rapidly obtained from small amounts of symbiotic (non-cultured) algae by gene amplification using the polymerase chain reaction.
Uptake and Persistence of Homologous and Heterologous Zooxanthellae in the Temperate Sea Anemone Cereus pedunculatus (Pennant).
TLDR
It is suggested that zooxanthellae from a range of host species and environments can establish symbioses with C. pedunculatus and that, over long periods under laboratory conditions, heterologous zooxanhellae may populate C. Pedunculatu to the same extent as homologous Zooxanthelae.
PHYLOGENETIC POSITION OF SYMBIODINIUM (DINOPHYCEAE) ISOLATES FROM TRIDACNIDS (BIVALVIA), CARDIIDS (BIVALVIA), A SPONGE (PORIFERA), A SOFT CORAL (ANTHOZOA), AND A FREE‐LIVING STRAIN
TLDR
Small subunit (SSU) ribosomal RNA gene sequences determined for 15 more Symbiodinium strains from 12 relatively unstudied host taxa suggest that polymorphic symbioses extend from cnidarians to some bivalve, foraminifer, and jellyfish host species.
Landscape ecology of algal symbionts creates variation in episodes of coral bleaching
TLDR
It is found that the ecologically dominant Caribbean corals Montastraea annularis and M. faveolata can act as hosts to dynamic, multi-species communities of Symbiodinium, implying that physiological acclimatization is not the only mechanism by which corals cope with environmental heterogeneity.

  • 1984
TLDR
It was shown that motile zooxanthellae were attracted to intact aposymbiotic host animals, but not to starved symbiotic hosts, and coelenterates and nitrate could be atractants.
The dynamics of zooxanthellae populations: A long-term study in the field
TLDR
Results from a 6-year field study are presented, providing evidence of density regulation but also of large variability in the zooxanthellae population with regular episodes of very low densities.
