Each solitary individual (oozooid) produces, by budding, a stolon which strobilates into chains, between 25 and 75 aggregated individuals (blastozooids), depending on the oozooid size (Heron & Benham, 1985), for Thalia democratica.
After this, several warnings were received during March across the ISCh: March 20 at Maillen Island (600 thousand oozooids and 54 thousand blastozooids per [m.
Salps were sieved and directly counted (no distinction between oozooids and blastozooids were made).
If a chimera were derived from fusion of a juvenile oozooid into a parental colony, the contribution of cells from each genotype would be expected to be different due to the age of the competing stem cells.
Unmanipulated clutches were monitored for fusion or rejection over the oozooid stage (less than 7 days old) and in the week after takeover by the first asexual generation (called a blastozooid, herein referred to as a zooid) 8-15 days post-settlement.
This produces high-density clutches of oozooids from a single mother (Table 1 shows densities for these experiments).
The resulting oozooid immediately begins to produce buds that originate as outgrowths from its lateral wall and are genetically identical to the parent.
