As any reader of Methods in Ecology and Evolution will know, advances in technologies and methodologies used by ecologists and evolutionary biologists are never-ending. Coupled with the tendency for researchers to become ever more specialised, this means that keeping up to date with all the advances is challenging at best. Occasionally, new advances revolutionise the kinds of questions we ask and encourage us to develop new approaches to answer them. One of these huge advances emerged from the ‘-omics’ revolution.

The application of -omics methodologies to evolution and ecology has been particularly rapid. These technologies usually aren’t part of the basic science education in these fields – it’s more usual for computational biologists to cross over to ecology and evolution than the other way around. The review by Simon Creer and colleagues ’The ecologist’s field guide to sequence-based identification of biodiversity’ helps bridge this gap. It’s not too technical, but sufficiently detailed, and it provides a very handy overview of how genomics, transcriptomics and their meta-analyses can be applied to evolutionary ecology. The paper is filled with enormously helpful workflows, pointers, examples and, as the title suggests, is a guide for those who are not experts in sequence based technologies. Continue reading
