Diverse ecological functions and the convergent evolution of grass awns. [PDF]

Am J Bot, 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

Threatened endemic arthropods and vertebrates partition their diets with non-native ants in an isolated island ecosystem. [PDF]

Ecology
Abstract The success of non‐native species depends on their ability to find food, which may ultimately lead to competition with native species and contribute to biodiversity loss in invaded ecosystems. Understanding which food resources are consumed is therefore crucial for evaluating how non‐native species mechanistically fit into native biological ...
