Traditional grazing management creates heterogeneous swards and fosters grasshopper densities

open access: yesInsect Science, Volume 29, Issue 6, Page 1805-1818, December 2022., 2022
Graphical Abstract Abstract Common pastures were once the dominant type of land use in many European regions. However, during the past 150 years, they have declined dramatically.

Diverse ecological functions and the convergent evolution of grass awns

open access: yesAmerican Journal of Botany, Volume 109, Issue 9, Page 1331-1345, September 2022., 2022
Abstract The awn of grasses is a long, conspicuous outgrowth of the floral bracts in a grass spikelet. It is known to impact agricultural yield, but we know little about its broader ecological function, nor the selective forces that lead to its evolution. Grass awns are phenotypically diverse across the extant ~12,000 species of Poaceae. Awns have been
