On ablation of the zooids, the remaining vascular tissue initially loses a small volume of hemolymph but quickly contracts its peripheral vessels to halt the oozing, and hemocytes start to aggregate (Fig.
Testes were selected for measurement in groups of four, with each group consisting of the two pairs of testes in neighboring zooids (ensuring that subsamples incorporated variation within testes pairs and between testes in neighboring zooids).
This suggests that none of the plasticity in the zooid morphologies that they detected was induced by biotic agents.
These juveniles were both at the single zooid stage while 98% of the juveniles in the controls had progressed to the two-zooid stage.
While some studies do report growth as increases in branch length, colony diameter, colony area, or number of zooids over time (e.
neritina mRNAs in the symbiotic and antibiotic-treated ovicell-bearing (with larvae) zooids and in the symbiotic and antibiotic-treated ovicell-free zooids.
Measurement of three zooids per colony in these species produces relatively stable colony means, with standard errors averaging only 6.
These projections can also bud additional zooids that, through asexual reproduction, can develop into a genet.
The among-colony component of zooidal morphologic variance thus can be obtained by partitioning the variance of zooids within colonies from total phenotypic variance.
fuscus, it appears that the zooids may deter settlement.
