Sentences with phrase «symbiont types»

As the larvae develop into mature polyps, coral typically keep the symbiont types best suited to the local microclimate and expel the others.

Different symbiont types can confer differential thermal tolerance [22], [23], and the types of symbionts harbored may change due to heat stress exposure, leading to increased bleaching resistance during later events [31].

However within a colony, a wide variety of symbionts can be harbored within a small percentage of polyps, although one symbiont type typically dominates.

Not exact matches

To find out if the symbionts help protect the aphids, Oliver's group injected bacteria - free aphids with three varieties of the bacteria — T - type, R - type, and U-type.

But it is still unclear whether it will be possible to manipulate symbiont populations effectively in the wild, where environmental conditions might cause the corals to favour one type of alga over another.

Since then, studies have shown that clade D symbionts, in particular types D1 and D1a, are prevalent in a wide variety of corals that have survived extreme bleaching events.

This is a pivotal consequence of life with symbionts, said Shapira, who believes that microbiotas, which involve many types of symbionts, represent an expanded version of this aphid - symbiont relationship.

Ironically, it is these burning fir trees that pose the only real fire threat to their sequoia symbionts, the burning trunk of a fir leaning up against the sequoia can lead to exactly the type of fire hollowing damage that we observe and that ultimately makes it possible for a dead sequoia to fall over at all, otherwise they might remain standing dead for a thousand years [not much good even for the squirrels].

The bar graphs list just the rarer symbionts and stars identify types not previously detected suggesting an ongoing shift.

Symbionts «types» are characterized first by their genetic lineages known as clades.

Scientists have found that coral colonies nearer the surface often harbor a different type of symbiont than colonies living just a few meters deeper.

The most heat resistant symbionts belong to clade D, but other heat resistant types have evolved within other clades.

Furthermore as conditions change, all species can shuffle their symbionts as polyps will expel their current residents and acquire a different type that had been harbored by a neighboring polyp.

A colony can also shift its symbiont population by acquiring new types not yet hosted by the colony but are present in the reef.

Sometimes by the same types of symbionts, sometimes by different ones.
