In general, however, the development of size distributions within a generation depends on three factors: (i) differences in initial sizes among individuals resulting from variable birth dates, (ii) differences in body growth within and among individuals, and (iii) losses or gains resulting from size-dependent survival, emigration or immigration.
Much of the reason may result from the size differences between people and spiders.
Although state of residence was not significant in univariate models, it was included in multivariable models to adjust for economic differences resulting from farm size, products, and differences in farming practices between states.
In vivo strain studies have also shown that in mammals, limbs of taxa of smaller body size are primarily loaded in tension, whereas compression predominates in larger taxa, resulting from postural differences with size (also related to the dynamic similarity hypothesis).
However, marked genomic divergence has occurred in the last two-thirds of the 60 80 million years since the main cereal grass lineages separated (Paterson et al., 2004), resulting in genome size differences that range from rice at 420 Mb to wheat at 16 000 Mb (Goff et al., 2002), compared with arabidopsis with a genome of 125 Mb (AGI, 2000).
By combining these two genomes into the same genomic environment, different enhancer content resulting from differences in genome size, may contribute to the patterns observed in gene expression of X. laevis, X. muelleri, and their F1 hybrid.
Two lines of evidence strongly suggest PC1 describes variance in structure volume resulting from differences in brain size.
To correct for large differences among toads in the basal flow rates for both arteries, we standardized all observations by dividing by the flow rate at t = -5 min. This helps to correct for differences resulting from animal size and physical condition at the time of experimentation.
Differences in herkogamy can result from both size and shape differences among blossoms (Armbruster et al. 2009).
For the analyses, we computed countries' overall cesarean rates per 100 live births as well as rates for singleton and multiple births; we further calculated rates per completed week of gestation starting at 26 weeks [ 19, 20] in order to reduce variability resulting from small sample sizes and differences in management at the earlier gestational ages.
Differences in coordination number may result from differences in the sizes of the ligands; for example, the iron(+3) ion is able to accommodate six fluoride ions in the hexafluoro complex [FeF6]>]3− but only four of the larger chloride ions in the tetrachloro complex [FeCl4]−.
