Basic knowledge about the rate and range of mutation is central to our understanding of numerous evolutionary processes that include maintaining sexual reproduction and rates of molecular evolution.

Comparing within-species variations of traits can be used in testing ecological theories. In these comparisons, it is useful to remove the effect of the difference in mean trait values, therefore ...

Variation is the differences between individuals of the same species, caused by genetic and environmental factors. Surveys into variation give data that are continuous, which means to come in a range, ...

Concerns about biodiversity tend to focus on the loss of species from ecosystems, but a new study suggests that the loss of variation within species can also have important ecological consequences.

There are three key aspects to genetic disease associations: comprehensive variant discovery, accurate allele-frequency determination, and an understanding of the pattern of normal variation and its ...

The rapid loss of variation within species is a hidden biodiversity crisis, according to a new study looking at how this variation supports essential ecological functions and the benefits nature ...

Since no two things are exactly alike, variation affects us in every aspect of our lives. Surprisingly, most American managers still don't pay much attention to variation. When they do look at it, ...
