In the patchy savanna environment, selection would have favored a foraging strategy that is efficient for an aggregative resource distribution.
Coverage of the Islamic world is patchy, and the selections from medieval Christendom seem capricious.
To provide a reference scenario, we describe evolution by natural selection in patchy landscapes without consideration of pest density.
Together these studies offer a rather patchy view of sex-specific selection in human populations.
Selection within these patchy habitats could thus have led to the evolution of adaptive plastic responses to high light (and concomitant moisture deficits).
Rather, these changes in physiological, developmental and fitness plasticity may result from selection in the patchy, temporally-variable light milieu of disturbed shade habitats in the species' introduced range (microsite data in T. Horgan-Kobelski, S. Matesanz, & S. E. Sultan, unpublished manuscript).
The study demonstrates the importance of considering simultaneously time and spatial scale dependencies, as well as the synergetic effects and the spatial arrangement of habitats in habitat selection studies, particularly in patchy dynamics environments such as farmlands.
Epidemiologic research may be affected by patchy data resulting in an unrepresentative sample, selection bias, misclassification, and confounding by factors associated with testing for and recognition of reduced kidney function.
Hall's tenure was troubled, not externally, but rather from Hall's patchy knowledge of the college and staff; his selection, faute de mieux, was sometimes questioned, although he remained well-liked.
In addition to drift, is selection driving the divergence and causing the patchy distribution?
