Linking landscape structure, floral resource distribution, pollen use and movement distances of a generalist predator

open access: yesJournal of Applied Ecology, Volume 61, Issue 11, Page 2798-2808, November 2024.
Our findings suggest that the spatial distribution of flowering wild plants can inform movement patterns of lacewings and other flower‐visiting insects in agricultural landscapes.

Soil carbon and nitrogen cycling at the atmosphere–soil interface: Quantifying the responses of biocrust–soil interactions to global change

open access: yesGlobal Change Biology, Volume 30, Issue 10, October 2024.
Despite the critical role of biological soil crusts (biocrusts) in dryland C and N cycles, little is known about how biocrust‐derived C and N move into the soil. This study reveals how biocrusts facilitate the downward movement of C and N and drive the formation of mineral‐associated organic matter in subcrust soils.
