Explants were taken when the colonies had grown sufficiently, and the colonies were tested for their ability to fuse to one another, using colony-based or polyp-based fusibility assays.
We performed 113 pairwise tests of fusibility between colonies recruited to a single shell.
By the same token, there is too little evidence to say much at all about his conception of weight, ductility, fusibility
and solubility in aqua regia.
Ontogenetic changes in fusibility
in the colonial hydroid Hydractinia symbiolongicarpus.
Shenk and Buss (1991) claim that fusibility declines with ontogeny and that some colonies disengage from fusion behavior with the onset of sexual maturity, suggesting that the costs of fusion are greater at this time.
Thus, fusion would not be favorable in competitive interactions between large colonies, and decreased fusibility with ontogeny (Shenk and Buss, 1991) would be expected.
In his treatise, Sammlung practisch-chemischer Abhandlungen (1797), Lampadius elaborated on his observations of fusibility, volume and color changes, odor and taste of the minerals tested with the blowpipe.
In 1837 he devised--analogous to Mohs's well known hardness scale--a six-step fusibility scale and demonstrated how similar mineral species might be differentiated by its application:
The tips of forceps and tweezers were made of platinum for holding a sample directly into the flame when testing its fusibility.
Twenty-three laboratory-raised colonies were typed at microsatellite 811 and were assigned to their fusibility
status by employing colony allorecognition assays (Rinkevich, 1992, 1995; Saito et al.
