Príklady niche

• Unlike pharmaceuticals, and apart from the giants mentioned above, the industry is highly fragmented, consisting of numerous small niche markets with a few products only.

• There were higher inter-habitat food niche overlaps within-species than between-species.

• Competition, contacts and other factors restricting niches of parasite helminthes.

• Our theoretical analyses, which employed two-locus, population-genetic models, uncovered a number of interesting evolutionary consequences of the feedback from niche construction.

• However, that does not mean there has been no evolutionary feedback from niche construction: it merely switches the evolutionary responses to the cultural domain.

• This is consistent with the view that it was filling a niche in the grammar, that is, speaker thought processing.

• In the following sections we argue that a niche construction perspective is particularly valuable in the study of human evolution.

• In many cases, the niche-constructed by-products of several organisms are exploited by a population.

• Apparently, species with smaller niches (= specialists) have less chance to survive deforestation and are more prone to local extinction than those with wider niches.

• Even here, however, the niche construction model so far promises more than it delivers.

• For humans, cultural information may be expressed in niche construction, but that does not make cultural evolution the same thing as niche construction.

• Yet clearly there was too little space under the roof of the southern niche for machinery of the sort that could work flyings.

• Although the south niche shows clearly in the groundplan, it must have been demolished, along with its side-linking walls and the staircases on either side.

• The mass of the enclosing walls is emphasised by the angled window splays, the thickness of the walls accentuated by the depth of the niches.

• These spiders tend to be quite specialized, exploiting narrow niches that preclude convective air currents.
