liberadas son capaces de asentarse enseguida que son liberadas y pueden colonizar areas cercanas a las de los progenitores.
The entrance to the Planula
Zone is characterised by a strong decrease in Sr/Al, P/Ti, Ca/Al, and TOC (Fig.
The fertilized egg develops into a planula
that is released into the water when mature.
These organisms are important because they are common on the wall and are also interesting because much work has been done with Spirorbis setigers (Knight-Jones 1951), bryozoan cyphonautes larvae (Keough 1984), and crawling Alcyonium planula
larvae (Sebens 1983).
The relationship between polyp-level reproductive variables (i.e., the number per polyp and volume of eggs, testes, and planula
) and colony size was determined using a single multivariate regression analysis for each species (Finn 1974:110).
That said, planula
larvae themselves are short-lived in A.
An estimation of the power of the seven loci to differentiate unique genotypes was done in two ways, both based on genotypic data from the CI population in which each colony was assumed to be the result of settlement of sexually produced planula
larvae and therefore genetically unique.
Night irradiance and synchronization of lunar release of planula
larvae in the reef coral Pocillopora damieornis.
larvae significantly increased, relative to uninoculated culture medium (MB) controls (P = 0.018, Fig.
It is possible that they are expressed during a narrow period of development (e.g., in the embryo or in the planula
larva, neither of which were used as a source of RNA here), or that they are expressed by stressed or wounded animals but not in healthy polyps, or even that alternative primer pairs would prove successful in initiating the PCR.
