Journal ArticleDOI
Reduced fecundity and offspring performance in small populations of the declining grassland plants Primula veris and Gentiana lutea
TL;DR: Study of reproduction and offspring performance in relation to population size in the declining self-incompatible perennials Primula veris and Gentiana lutea suggests that small populations may face an increased short-term risk of extinction because of reduced reproduction, and an increased long- term risk because they are less able to respond to environmental changes.
Journal ArticleDOI
Offspring fitness in relation to population size and genetic variation in the rare perennial plant species Gentiana pneumonanthe (Gentianaceae)
TL;DR: In this paper, an analysis was made of variation in a number of life-history characters in relation to population size and offspring heterozygosity (based on seven polymorphic isozyme loci).
Journal ArticleDOI
Temporal and spatial variation in the demography of Gentiana pneumonanthe, a rare perennial herb
TL;DR: In this article, a total of 35 transition and elasticity matrices for the rare iteroparous herb Gentiana pneumonanthe was analysed for temporal and spatial variation.
Journal ArticleDOI
Population structure of the rare, long-lived perennial Gentiana pneumonanthe in relation to vegetation and management in The Netherlands
TL;DR: The structure of the surrounding vegetation appears to be very important in determining the populationructure of the marsh gentian, and the percentage of bare soil surface and the cover of the litter layer explain most of the variation in the density and proportion of different age states in the populations.

How perennial are perennial plants
Johan Ehrlén,Kari Lehtilä +1 more
TL;DR: In this paper, the empirical examination of such patterns has so far been limited by the fact that information on life span has not yet been available, which is a limitation in the molding of plant life histories.

Journal ArticleDOI
The bottleneck effect and genetic variability in populations
TL;DR: In a population of constant size the expected heterozygosity for a neutral locus when mutation and genetic drift are balanced is given by 4 Nv/(4Nv + 1) under the assumption that new mutations are always different from the pre-existing alleles in the population.

Pollination in Dianthus deltoides (Caryophyllaceae): effects of habitat fragmentation on visitation and seed set
TL;DR: The effects of habitat fragmentation on the pollination success of a perennial, butterfly-pollinated, caryophyllaceous herb, the maiden pink, Dianthus deltoides L. Deltoides is analyzed.

The Biological aspects of rare plant conservation
Barry R. Flamm,Hugh Synge +1 more
TL;DR: 'Between 14 and 19 July 1980, about 160 botanists gathered at King's College, Cambridge, to discuss and explore how the many varied disciplines of the biological sciences can be translated into practical conservation management to save rare and threatened plants.
