The August issue of Methods is now online!
This month’s issue of is even bigger than our July issue. In 250 pages of exciting ecology and evolution, we’re covering the Methods in Ecology and Evolution impact of biologgers, seed dispersal, interactions between individuals, and loads more.
With the extra long issue, comes more free articles. There are ELEVEN papers in our August issue that are free to access for absolutely anyone. You can find out about the four
Practical Tools papers and seven Applications articles below.

Stable isotopes as a tool for ecologists
Our research into the foraging ecology of this cheeky parrot (kea: Nestor notabilis) prompted us to develop a simple method to establish discrimination factors © Andruis Pašukonis
Isotopes are atoms that have the same number of protons and electrons but differ in their number of neutrons; they are lighter and heavier forms of the same element. Unlike radioactive isotopes, stable isotopes do not decay over time.
The ratio of heavy to light stable carbon (δ
13C) and nitrogen (δ 15N) isotopes in an animal’s tissues depend on its diet, although offset by a certain amount. This integration of δ 13C and δ 15N from an animal’s diet into its tissues allows ecologists to use stable isotope analysis to investigate a species’ present and historical diets, food-web structures, niche shifts, migration patterns and more.
