Experimental methods for measuring gene interactions

Article Abstract:

The experimental methods for measuring epistasis are reviewed, some that are commonly used but weak and others that are less frequently used but stronger. The statistical genetic methods are also reviewed based on analyses of variances and means as well as molecular genetic methods for detecting gene interactions. It is concluded how technologies for investigating genome-wide epistasis are bridging the gap between physiological and statistical epistasis for model organisms.

Birth-death models in macroevolution

Article Abstract:

Birth-death models and their subsets such as the pure birth and pure death models are used for informing thinking about macroevolutionary patterns. The usage of these models in addressing wide range of questions including estimating and comparing rates of diversification of clades, investigating the 'shapes' of clades and some other uses is illustrated.

The functional significance of ribosomal (r) DNA variation: Impacts on the evolutionary ecology of organisms

Article Abstract:

A review to integrate information about structural and functional aspects of rDNA that impact the ecology and evolution of organisms is presented. There are strong reciprocal feedbacks between rDNA and the ecology of all organisms mediated through increased phosphorous demand in organisms with high rRNA content.
