Mass housing initiatives and individual "gentrification" of terraced houses tended equally to reduce population density.
Lowering of the proliferation rate towards the interval boundaries is required in order to reduce population density tails.
Secondly, endosymbionts reduce population density and thus relax intraspecific competition [ 15].
Early theory commonly considered a situation where events of high density-independent mortality, for example due to environmental seasonality, reduce population density (e.g. Pianka 1970; King and Anderson 1971; Roughgarden 1971).
Similarly, sweet potato was found to significantly reduce population density and importance values of invasive alien species Ageratum conyzoides, Bidens pilosa, Eleusine indica, and Galinsoga parviflora and native species, Digitaria sanguinalis and Portulaca oleracea in China [ 34].
After co-inoculation, WCS358 reduced population densities of wild-type WCS374 by up to 30-fold, whereas WCS374pMR, a WCS374 derivative harboring the PVD358 receptor pupA of WCS358 maintained its population density.
Mass mortality severely reduced population density during winter.
Half of them are first, second or third generation immigrants, largely from North Africa, and 70percentt of those live in the projects, which are undergoing a $140 million renovation aimed not only at modernizing them but also at reducing population density.
Thus, if fishing reduces population density, the effects of sexual selection may become small.
If reduced population density benefits older individuals more than younger individuals, then increased extrinsic mortality might indeed improve the prospect of older individuals and thus lead to a slower decline in the strength of selection with age [ 16].
