As well know, the quality of herbal medicines can be affected by many factors, such as geography, seasonal variation, cultivation, harvesting, storage and post-harvest treatment.
Due to his background in taxonomy and paleontology, Cope focused on evolution in terms of changing structure, rather than emphasizing geography and variation within populations as Darwin had.
The rates of these treatments vary dramatically in different geographies; this variation cannot be explained by diagnostic characteristics or preferences of the patients [ 1- 3].
He peers at the book from multiple angles — those of biography, geography, publishing, textual variation, and mild erotic sleuthing, among others — as if hoping to catch it at an unfamiliar slant.
This data is all organizable by device type, geography, experiment and variation allocation, as well as any customer defined custom variables.
Practically, these results emphasis the need to develop balanced and crossed designs among the sources of variation (geography, time, depths).
The strong relationship between genetic variation, geography, and historical record supports the hypothesis that the admixture analysis used here is a reasonable approach for predicting within-Africa ancestry.
The influence of geography on genetic variation was also explored using SAMOVA, but no clear geographic groupings showed significant "among group" values (data not shown).
In a first step, we analysed the correlation between LCT*P variation, geography, and the variation of other independent polymorphisms at different geographic scales, to check whether LC T*Pgenetic patterns were really peculiar or could have been shaped, at least in part, by population history and demography.
We investigated the impacts of Wolbachia infection and geography on mtDNA variation in the diamondback moth, a major global pest whose geographic distribution reflects both natural processes and transport via human agricultural activities.
