Sentence examples for propagules from inspiring English sources
Still others have elaborate mechanisms for spreading via rhizomes, stems, or other propagules.
On the other hand, large patches will persist longer as land or seascape features; they require more time to invade, and their recovery is dependent on propagules produced elsewhere, especially in places where no remnants of the disturbed community survived.
Other organisms adjust to seasonal temperature drops by developing dormant propagules such as spores, eggs, or tuns, which are hardy desiccation- and radiation-resistant forms produced by microscopic animals called tardigrades, also known as "water bears".
The floating propagules are commonly dispersed aquatically, and the fruits of some species can be viable for up to a year in salt water without rooting.
However, some of these communities needed to be recolonized by propagules, spores in this case (other kinds of propagules include seeds and eggs), coming from other beds hundreds of miles away.
They require more time to invade, and their recovery is dependent on propagules produced elsewhere, especially in places where no remnants of the disturbed community survived.
However, propagule transport can span long distances for fugitive or "weedy" species, which are specially adapted to invade and thrive in disturbed environments.
Each propagate is made up of individuals derived from a single population, and there is no mixing of colonists from the different populations during propagule formation.
They conclude that, by using propagule pools as the assumption about colonization, one can greatly expand the set of parameter values for which group selection can be effective (Slatkin and Wade 1978, cf. Craig 1982).
On the basis of Slatkin and Wade's analysis, much more between-population genetic variance can be maintained with the propagule model (1978, p. 3531).
