Microsatellites. Sixteen individuals from each population were genotyped at 12 loci. Eight of these loci were designed for R. minor (Houston and Wolff, ), while Ra 57, Ra 61, Ra 75, and Ra were developed for R. angustifolius (Ducarme et al., ).Details of PCR reactions and processing of samples can be found in Houston and Wolff () and Ducarme et al.

Extraction of xylem sap by the parasite from the host’s roots is facilitated by con siderably higher transpiration per leaf area in the parasite than in the host and by the fact that Cited by: Professor L.

Bringing. The generalist hemiparasitic plant Rhinanthus minor L. is a natural component of European grasslands (Westbury, ), with widespread distribution throughout northern Europe.

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.
Action: Add yellow rattle seed Rhinanthus minor to hay meadows Key messages Read our guidance on Key messages before continuing. 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.
They both emphasized such things as cell structure, chemistry, and the classification of plants and animals. This book is one of a series of colorfully illustrated texts from the same publisher, all of which emphasize "issues," giving the impression that such concerns are more /5(2).
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.
