They conceptualized a bioregion as an area defined by a unique pattern of natural characteristics (e.g. climate, landforms, watersheds, soils, native plants and animals) and included people as an integral aspect of a place [ 39].
A final complication is that a regular pattern of natural climate change over the North Atlantic, called the multi-decadal oscillation, may be about to enter a cooler phase, just as it did in the 1960s, when Britain also experienced colder-than-normal winters.
Our findings show a complex and changing pattern of natural selection drove hominin hip evolution, and that many, but not all, traits hypothesized to play functional roles in bipedalism evolved as a direct result of natural selection.
Based on the dynamic nature of biologic systems, any predicted outcome is vulnerable to change in response to new diseases, or a shift in the pattern of natural disease processes or progression.
Therefore, the possibility exists of altering the glycosylation pattern of natural products, thus enabling an increase in the structural diversity of natural products.
In 2010, the European Medicines Agency (EMA) focused their attention on patients treated with lower doses of agalsidase beta noting an increase in adverse events in these patients; specifically "a pattern of adverse events resembles the natural, but accelerated, course of Fabry disease"[ 78].
This pattern of natural selection could result either from a tendency of the upstream genes to be under positive selection or from increasing purifying selection operating along the pathway.
In this scenario is built a polycentric model of tourist development, in alignment with the spatial pattern of natural and cultural reserves of each single part of the study region.
The pattern of natural selection acting during the evolutionary history of a gene family can be illuminated by comparing the rate of nucleotide substitutions that change the protein sequence (Ka) to the rate of nucleotide substitutions that do not (Ks).
The pattern of natural selection that emerges in this model is a feature of human influenza dynamics, but it does raise intriguing possibilities for understanding the dynamics of influenza ecology more generally.
