How much do you think about the world beneath your feet? Soil is essential for life on earth and provides many ecosystem services, including carbon storage and providing habitats for billions of organisms. But one third of our global soils are already degraded and are at risk of further degradation from human activities, such as unsustainable farming practices, industrial activities, mining and other non-environmentally friendly practices. In 2002, the International Union of Soil Sciences (IUSS) marked the 5th December as World Soil Day, to celebrate the importance of soil as a critical component of the natural system and as a vital contributor to human well-being.

To mark this World Soil Day, I’m going to be highlighting my recent study, which used DNA metabarcoding as a method to investigate soil microbiomes for evaluating the success of forest restoration in Costa Rica.

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.

Find out a little more about the new issue of Methods in Ecology and Evolution below. Continue reading
