Mapping Scytonemin Pigment Content and Biocrust Functional Indicators Using High‐Resolution Multispectral Imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...

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 ...

Degradable versus inert microplastics: Effects on soil organic carbon persistence via microbial drivers in an agroecosystem

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Microplastics (MPs) are widespread in terrestrial ecosystems, raising global concerns that they may disrupt soil organic carbon (SOC) cycling and undermine agroecosystem contributions to climate mitigation.
