subniche

Age-related subniche and reproductive biology of Parachondria neglectus (Littorinimorpha: Annulariidae) in Manzanillo, Cuba

There are some formidable vehicles in the hot hatch division, but the Golf GTI almost campaigns in its own subniche.

"But that does not mean there is not an affluent subniche that is profitable to go after," she adds.

It's a form of professional feather display, the ritual gesturing by which scholars establish standing with others in their particular niche, or subniche, of the scholarly trade.

But once started, it could make tremendous changes: think of niche vehicles with their own subniches.

Today, the sites each carve out subniches within their niche.

According to Vrijenhoek (1979, 1984, 1989), this would compromise the long-term survival of the unisexual complex as new lineages could not compensate the demise of individual lineages due to Muller's ratchet or the eventual disappearance of clonal subniches. Consequences of the impediment to creation of new lineages would be most striking if extensive environmental changes occurred; even a very large asexual population might not have a lineage with the appropriate genotype and become extinct (Crow 1992).
