Extreme stresses, niches, and positive species interactions along stress gradients
Ecology, 2014Since proposed two decades ago, the stress‐gradient hypothesis (SGH), suggesting that species interactions shift from competition to facilitation with stress, has been widely examined. Despite broad support across species and ecosystems, ecologists debate whether the SGH applies to extreme environments, arguing that species interactions switch to ...

Correspondence of seed traits with niche position in glacier foreland succession
Plant Ecology, 2011Changes in species composition during succession are driven by biotic and abiotic factors leading to a multitude of niches occupied by distinct species. Gradient analyses of plant communities provide opportunities to approximate the niche position of species along a successional gradient.

Strategic Positioning of Goods in a Market with a Niche [PDF]
, 2013 We use the Hotelling's model allowing for a "gap" in the consumers' preferences. As a result, the characteristics space is divided in two separate intervals. The largest one represents the main market, and the smallest represents a niche. We find that in this set up the principle of maximum differentiation may not hold.

American Journal of Botany, 1978
The close systematic affinities between the composite genera Haplopappus and Chrysothamnus, including different points of contact with “intergeneric” hybrids, are reviewed. The Mohave Desert has several shrubby representatives of each genus, and at census sites from the east‐central New York Mountains to buttes at the extreme western end of the desert,

Positioning against niche competitors to reduce revenue erosion.
Health care strategic management, 1999Health care providers around the country face a growing threat from more limited service "niche" providers, often sponsored by specialty physicians. Mark Grube, vice president of Abendshien+Grube Associates, writes that hospitals and health systems may want to consider joint ventures with physicians to counter this trend.

[Normal position of the stapes in the oval window niche in man].
Anatomischer Anzeiger, 1986A study of mastoid bones showed a central position of stapes only at 67%. At 21% a deviation exist to the side of promontorium and at 12% a position directly at the promontorium. Secondly is to remark the position of the posterior crus incudis lateral on the footplate to the side of promontorium.
