propagule

The propagule is usually distinct in form from the parent organism.

In sexual reproduction, a propagule is a seed or spore.

Without propagule pressure the number of invasive species incorporated would be unpredictable.

The dynamics of the invasion are influenced by propagule pressure even after establishment has taken place.

The mature propagule then drops into the water, which can transport it great distances.

In most studies a direct relationship is observed, the higher the propagule pressure the higher the success of the invasion.

It considers the fact that each propagule has an independent chance of establishment:

The propagule then becomes detached from the branch when sufficiently well developed to root in the mud below.

Cryptococcosis is believed to be acquired by inhalation of the infectious propagule from the environment.

A mangrove propagule may float in brackish water for over a year before rooting.

In horticulture, a propagule is any plant material used for the purpose of plant propagation.

When a fungal propagule lands on a suitable piece of timber, it will grow if no other fungi are present.

After 3 to 6 months, when the propagule is mature, it drops into the water where it can then be transported great distances.

As a viviparous plant, R. mangle creates a propagule that is in reality a living tree.

Measures of propagule pressure are have been shown to have specific relationships with the probability of establishment.

The whole idea of plants controlling the rate of passage of a propagule, like a seed, is a wonderful, open question.

Parasite identification Parasites were identified to the genus or family level from the propagule morphology.

To properly understand propagule pressure it is also important to realize that it is actually in flux within nature.

This death would allow the propagule to split off cleanly at the site of the dead cell, improving the efficiency of reproduction.

Once a propagule is ready to root, its density changes so the elongated shape now floats vertically rather than horizontally.

The conservative estimate of the number of biotypes based on propagule morphology was 12 and a liberal one was 21.

The seed does not detach itself from the flower stalk but germinates where it is and is known as a propagule.

One important concept of propagule pressure is how it can be used to predict and or prevent invasions of nonnative species in high risk locations.

Although the exact nature of the infectious propagule is unknown, the leading hypothesis is the basidiospore created through sexual or asexual reproduction.

One type of propagule is the ungerminated spores, which must percolate through the soil beyond the reach of light in order to germinate.
