Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Mammalian herbivory indirectly shapes savanna arthropod communities but only at very low or high levels

Journal of Animal Ecology, EarlyView.
This study investigates how large mammalian herbivores shape arthropod communities in African savannas, using a broad gradient of herbivory types and intensities to assess these effects under real‐world, non‐experimental conditions. Abstract Savanna ecosystems support unique biodiversity and provide livelihoods for millions of people.

Misalignment in Carbon Credit Programmes: Insights From Producer Preferences for Cover Crop and No‐Till Contracts

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT This study examines the factors influencing producer adoption of cover cropping and no‐till farming, two key carbon sequestration practices, within the context of voluntary carbon credit programmes (CCPs) in Kansas. Using a mixed‐methods survey that combines discrete choice experiments with farm‐level data from 370 producers, we estimate ...
