This pretty little annual sends out roots that grow into the roots of neighbouring grass plants, and steal nutrients (that is, food) from them. It will produce many tiny seeds that rattle around in the papery brown calyx - hence the common name - and it can spread itself year by year, weakening the poor, hard-working grasses.

A review of studies from the UK found that adding hay rattle seed helped other sown target meadow species to colonize and that more plant species were found when yellow rattle was present.

R. angustifolius is classed as a neophyte having been introduced to the British Isles after AD and is listed as a Red Data Book species (Perring & Farrell ), while R. minor (here after referred to as Rhinanthus), is native and has been recorded in all vice-counties, typically being found in association with hay meadow communities Cited by: (page ) I compared this book to two other biology textbooks.

The development of population ecology owes much to demography and actuarial life tion ecology is important in conservation biology, especially in the development of population viability analysis (PVA) which makes it possible to predict the long-term probability of a species persisting in a given habitat patch.
