Genetics and Conservation of Rare Plants

TL;DR: Section One: Population biology and genetics of rare species Section Two: Distribution and sampling of genetic variation Section Three: Management and assessment of off-site collections Section Four: Conservation strategies for genetic diversity
Journal ArticleDOI

Protandrous arrival timing to breeding areas: a review

TL;DR: It is shown that the degree of multiple mating by males and the occurrence of male territoriality seem to determine the relative importance of each hypothesis, and the adaptive significance of sex-biased timing needs to be understood.
Book ChapterDOI

The loss of sex in clonal plants

TL;DR: Wide variation in genotypic diversity and gene flow associated with the loss of sex may constrain local adaptation and the evolution of the geographical range limit in clonal plants.
Journal ArticleDOI

Insect pollinated plants benefit from organic farming

TL;DR: The results show that insect pollinated plants benefit disproportionately from organic farming, which appeared to be related to higher pollinator densities in organic fields, whereas in the centres of conventional fields non-insect pollination plants dominate presumably due to a limitation of pollinators.
Journal ArticleDOI

Constraints on the evolution of asexual reproduction.

TL;DR: The intimate evolutionary relations between haplodiploidy and parthenogenesis as well as implications for the clade selection hypothesis of the maintenance of sexual reproduction are also discussed.

The evolution of self-fertilization and inbreeding depression in plants. i. genetic models

TL;DR: Genetic models are constructed which allow inbreeding depression to change with the mean selfing rate in a population by incorporating both mutation to recessive and partially dominant lethal and sublethal alleles at many loci and mutation in quantitative characters under stabilizing selection.
Journal ArticleDOI

The Maintenance and Breakdown of Distyly

TL;DR: An algebraic analysis of the equilibrium reached as a result of the opposition of selection and recombination in a heterostyled population is presented and it is shown that the self-fertile homostyle with the dominant allele for pollen type will usually replace heterostYly.
Journal ArticleDOI

Is there disruptive selection for self-fertilization?

TL;DR: Lande and Schemske (1985) recently proposed a more dynamic model that allows the selling rate to evolve while its effects on the segregational oad (and hence the relative fitness of selfed and outcrossed progeny) are taken into account, and comment on the framing of their model and the interpretation of the outcrossing-rate data.
Journal ArticleDOI

Breeding system polymorphism in a heterostylous species.

TL;DR: The occurrence of distylous and tristylous populations of Oxalis alpina (section Ioenoxalis), a species of the southwestern United States, Mexico and Guatemala, suggested that studies of this species could provide further information on the evolutionary relationship of distyly and trstyly, and indicate how changes in heterostylous breeding systems have occurred.
