Scientists have shown that many
different types of algae are related only distantly, despite the fact that they may look similar.

There are more than 400
different types of this Symbiodinium
algae and thousands
of different coral reefs.
Instead, they discovered that each V. carteri cell
type expresses orthologs
of genes from
different temporal phases
of the light — dark cycle in a related unicellular
alga, Chlamydomonas reinhardtii, with somatic cells enriched for expression
of dark - phase genes, and gonidial cells enriched for expression
of light - phase genes.

Epiphytic
algae of many
different types covers the parts below the high tide mark and lichens
of many forms and colors cover the branches where the tide never reaches.
This area boasts more than 160
different species
of fish and many
different corals,
algae and several
types of sea turtles.
But thanks to technological advances in genetic sequencing, we now know a coral species can harbor several potential species or
types of Symbiodinium
algae, each capable
of responding optimally to a
different set
of environmental conditions and coral physiology.
However, we demonstrated that there is specialisation
of the coral host to particular reef environments, with each strain
of coral host associating only with particular
types of symbiotic
algae... the results also highlight the lack
of connectivity between
different habitats on a single reef, such as shallow and deep water, which has important implications under future climate change scenarios, as coral reefs will be largely dependent on neighbouring areas for their recovery.
We also need in situ measurements in the GrIS's ablation zone that can distinguish the relative contributions
of different impurity
types (e.g., black carbon, dust,
algae) to albedo reduction as well as models that accurately simulate the GrIS surface energy balance and mass balance.
