The effective population size is required to predict the rate of inbreeding and loss of genetic
variation in wildlife. Since only census population size is normally available, it is critical to …

Trees do not form a natural group but share attributes such as great size, longevity, and high
reproductive output that affect their mode and tempo of evolution. In particular, trees are …

Invasive species are predicted to suffer from reductions in genetic diversity during founding
events, reducing adaptive potential. Integrating evidence from two literature reviews and two …

To select candidate populations of wild species to be given priority for conservation, genetic
criteria gained from the study of molecular markers may be useful. Traditionally, diversity …

Genetic diversity at nine isozyme loci was surveyed in an endangered tree species, the
argan tree, endemic to south-western Morocco. The species is highly diverse (3.6 …

Biodiversity refers to variation within the living world, while genetic diversity represents the
heritable variation within and between populations of organisms, and in the context of this …

The impetus for this book arose out of my previous book, The Evolution of Life Histories
(Roff, 1992). In that book I presented a single chapter on quanti tative genetic theory …

The Conservation of Plant Biodiversity takes an evolutionary perspective to the conservation
of plant biodiversity, stressing the need to explore both current and long-term issues. It …

Identifying traits that affect rates of speciation and extinction and, hence, explain differences
in species diversity among clades is a major goal of evolutionary biology. Detecting such …

Levels of neutral genetic diversity in populations subdivided into two demes were studied by
multi-locus stochastic simulations. The model includes deleterious mutations at loci …
