Issue 10.7: Aquatic Ecology, Zeroes, Sequencing and More

The July issue of Methods is now online!

We’ve got a bumper issue of Methods in Ecology and Evolution this month. In the 200+ pages, you’ll find articles about measuring species distributions and abundances, integrated population models, and working at the whole-plant scale.

We’ve got six papers that are freely available to absolutely everyone this month too. You can find out about two of the Open Access papers in the Applications and Practical Tools section below. In the third, Chen et al. show that tree assemblages in tropical forest ecosystems can present a strong signal of extensive distributional interspersion.

Pathogens and the infectious diseases that they cause can have devastating impacts on host individuals and populations. To better understand how pathogens are able to cause disease, we can investigate the genetic mechanisms underlying the infection process. Hosts may respond to infection by upregulating defence pathways. Pathogens, in turn, evade these host immune responses as they infect and cause disease. As this process unfolds and each organism responds to the other, gene expression changes in both the host and the pathogen. These gene expression changes can be captured by dual RNA‐seq, which simultaneously captures the gene expression profiles of a host and of a pathogen during infection. Continue reading
