Although the potential genetic risks associated with rare or endangered plants and small
populations have been discussed previously, the practical role of population genetics in …

Conservation of genetic diversity, one of the three main forms of biodiversity, is a
fundamental concern in conservation biology as it provides the raw material for evolutionary …

No species occurs everywhere. Indeed, the majority are absent from most places, and where
they do occur they are usually quite rare. Gaston discusses the structure of these …

Genetic diversity is one of three levels of biological diversity requiring conservation. Genetic
theory predicts that levels of genetic variation should increase with effective population size …

Summary 1 Relationships between plant population size, fitness and within‐population
genetic diversity are fundamental for plant ecology, evolution and conservation. We …

Rare species are typically considered to maintain low levels of genetic variation, and this
view has been supported by several reviews of large numbers of isozyme studies. Although …

The study of variability within species is important to all biologists who use genetic markers.
Since the discovery of molecular variability among normal individuals, data have been …

Although biological invasions are clearly one of the most important impacts humans have
had on the Earth's ecosystems, we still do not have reliable tools which can help us to …

The absence of gene flow, genetic isolation, is frequently emphasized in conservation
genetics. However, the presence of gene flow can play an equally important role in …

I analyse the effects of habitat fragmentation on the pollination success of a perennial,
butterfly‐pollinated, caryophyllaceous herb, the maiden pink, Dianthus deltoides L. The …
