Beyond Species Diversity: Functional Approaches Reveal Consistent Fauna Community Responses to Exotic Grass Invasion in Arid Lands

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
To assess whether the impacts of exotic plant invasion can be generalised across taxa, we developed a conceptual framework predicting faunal responses to grass invasion in open, arid ecosystems and tested our predictions using data on birds, reptiles and ants from sites invaded by buffel grass (Cenchrus ciliaris) and paired uninvaded sites.

Comparative gene expression analysis among vocal learners (Bengalese finch and budgerigar) and non-learners (quail and ring dove) reveals variable cadherin expressions in the vocal system

open access: yesFrontiers in Neuroanatomy, 2011
Birds use various vocalizations to communicate with one another, and some are acquired through learning. So far, three families of birds (songbirds, parrots, and hummingbirds) have been identified as having vocal learning ability.
