(2003) followed the fitness of Drosophila melanogaster populations that differed in inbreeding rate over a range of inbreeding coefficients and found that the decrease in population survival with increasing level of inbreeding was faster in populations with fast inbreeding.
Although the power of admixture mapping decreases in populations with a much larger contribution from only one parental population [ 26], the map power is fairly constant for values of admixture proportion from 10%to90%0% [ 3].
In line with predictions based on concession models, skew among males of the same group decreased in populations with a measurable loss of paternity to extragroup males (EGP > 0), as compared with populations experiencing no EGP (80.4 ± 18.8% alpha male paternity within group in 10 populations without EGP and 40.9 ± 20.4% in 7 populations with EGP, t = 4.02, P < 0.001).
The decrease in population growth rates with heavy harvest results from reduced individual rates of growth and reduced seedling regeneration (Mandle 2012; Mandle and Ticktin 2012).
A decrease in population and community variability with increasing species richness has been reported previously for tropical rock pool meiofauna [24], [26], [28], [35] [37], pond zooplankton [30], and some plant communities [38].
The temporal land consumption pattern exhibits low density urban growth in Srinagar, Dehradun and Kathmandu, as observed with decrease in population density and increasing land consumption during 1972 2015 as compared to other cities, wherein urban densification was evident with increase in population density and decrease in land consumption.
Greater mating success of diploid males was also associated with a decrease in population growth and an increase in the probability of population extinction.
As the population doublings increased, telomeres shortened, the culture took longer to double, and rearranged telomeres were detected at a point coincident with a decrease in population doubling time.
Over the U.S. population, BPb change measured between 1976 and 1999, Nawrot's coefficient translates into a 4.1 mm Hg decrease in population systolic blood pressure, a change with significant health and economic benefits.
The lower fitness of homozygous individuals than of heterozygotes nonetheless generates a severe genetic load, leading to a "diploid male vortex", with a decrease in population size resulting in a decrease in heterozygosity at the csd gene, an increase in the proportion of diploid males, a decrease in population growth rate, and, if severe enough, a further decrease in population size [ 32].
