The Genealogical World of Phylogenetic Networks
This blog is about the use of networks in phylogenetic analysis, as a replacement for (or an adjunct to) the usual use of trees. This topic has received considerable attention in the biological literature, not least in microbiology (where horizontal gene transfer is often considered to be rampant) and botany (where hybridization has always been considered to be common). It has also received increasing attention in the computational sciences, although the dialog between the biologists and the mathematicians is not always as clear as it should be. Networks are acknowledged to have two main uses within phylogenetics: (i) exploratory data analysis, in which conflicting data patterns are visualized and their nature and quantity assessed; and (ii) evolutionary analysis, in which the historical patterns involve not only vertical descent (parent to offspring) but also reticulations due to horizontal processes (such as HGT, hybridization, recombination, and genome fusion).

Results of some bioinformatics polls
In 2008, Michael Barton conducted a Bioinformatics Career Survey . Since then, various groups have updated some of that information by conducting polls of their own. Below, I have included some of the more recent results, for your edification. This first ...1 day ago
