Nevertheless, the main driving forces are different: the wild flora are homogenized by diminished species richness difference while the cultivated flora due to the decreased species replacement.
Additionally, the database considers one quality measure for the fingerprint modality (e.g., texture richness), and three quality measures for the iris modality (e.g., texture richness, difference between the iris and pupil diameters, and proportion of the iris used for matching).
Low species richness differences are caused by species pool biases toward those ones capable to survive at degraded ecosystems, suggesting that the effects of water parameters are much less important than a landscape dominated by pastures and practically without forests.
The p-values for richness differences were calculated using a Wilcox rank-sum test on the rarefied richness and diversity measures.
In order to illustrate results expected when controlling and measuring only one of those two parameters and leaving the other as a hidden treatment, regressions were also performed on the three levels of genotypic richness ignoring allelic richness differences, and the effect of allelic richness was assessed by regression for each genotypic richness treatment.
It is interesting to note the tendency of the mitochondrial genes to produce "polygonal plots" as when the difference in species number is less than a factor of two (i.e of 1 on our log2 scale), then the rate difference is highly variable, whereas the relationship appears somewhat more obvious when the richness differences are more dramatic.
Sister-clade comparisons are a good way of testing for species-richness differences if a sufficient number of pairs are available to provide power to the test.
Mean population allelic richness was significantly negatively related to distance from PNG, with distance explaining 75% of the variation in allelic-richness differences between sites (Adj R = 0.75, F1, 29 = 91.57, P < 0.001; Fig. 3A).
There's no need to melt away diversity when the richness of difference is embraced with respect.
Finally, when taken together, results suggest that for forests across the Amazonian landscape differences in flooding regime may have a greater effect on both seed rain load and seed species richness than differences in availability of soil nutrients.
