These neurons have the fascinating property of being selectively active when the rat occupies restricted locations in its environment.
However, its distribution is discontinuous and scattered; it occupies small, restricted areas as a result of having been extensively exploited by humans over the past 1000 years (Ohba 1993).
The global marginality value was higher for the M form (1.230) than the S form (1.075); these figures indicate that both molecular forms occupied a restricted subset of environmental conditions of those available across Cameroon.
Its distribution is limited to 13 counties and it appears to occupy a restricted habitat within those counties, often observed on the edges of upland drainages in small open grass/shrub patches within post-oak savannah/woodland communities (Wonkka et al. 2012).
burgessi, H. davenporti, H. spinigularis, H. tanneri, H. minutissimus, and H. ukwiva) [ 45], with species occupying localities often restricted to either montane mosaic or rainforest habitats [ 26, 46– 46].
This would result in a quarter of their offspring becoming homozygous for the adaptive trait, which they would hence express more strongly, and would possibly be restricted to occupying only the newly colonised niche, with little or no possibility of contact with the ancestral one.
Rare and sedentary species are particularly vulnerable to habitat fragmentation as they occupy narrow niches or restricted habitat ranges.
The enthalpy of mixing (the polymer and the nanofiller) measured could explain the cause of the repulsive interactions between the nanoparticles and the polymeric chains, which created an additional excluded volume that the polymeric segments were restricted to occupy, thus forcing the conformational characteristics of the polymeric chains to deviate away from those of the bulk chains.
For binary trees of size A, where nodes are restricted to occupy uniformly a D dimensional Euclidean space, the minimum value of C scales as Aη, with η = (D+1)/D.
