Integrating demographic and genetic approaches in plant conservation
Abstract We summarize the problems that populations of formerly common plants may encounter when habitat fragmentation isolates them and reduces population size. Genetic erosion, inbreedingExpand

Temporal and spatial variation in the demography of Gentiana pneumonanthe, a rare perennial herb
1 A total of 35 transition and elasticity matrices for the rare iteroparous herb Gentiana pneumonanthe was analysed for temporal and spatial variation. The data used were collected annually from 10Expand

Population structure of Salvia pratensis in relation to vegetation and management of Dutch dry floodplain grasslands
Summary 1 We need to understand how threatened plant species respond to natural or management-induced habitat changes to conserve them successfully. Because long-term demographic studies areExpand

Invasive behaviour of Lactuca serriola (Asteraceae) in the Netherlands: Spatial distribution and ecological amplitude
Summary Species invasions have been a central theme in ecology over the past decades, with a focus on invasions of non-indigenous European species in the New World. However, within Europe, nativeExpand

Population structure of the rare, long-lived perennial Gentiana pneumonanthe in relation to vegetation and management in The Netherlands
After analysis of population age-state spectra of Gentiana pneumonanthe in a variety of vegetation types, three different population types could be distinguished: (a) «invasive» or «dynamic»Expand

Offspring fitness in relation to population size and genetic variation in the rare perennial plant species Gentiana pneumonanthe (Gentianaceae)
Seeds were sampled from 19 populations of the rare Gentiana pneumonanthe, ranging in size from 5 to more than 50,000 flowering plants. An analysis was made of variation in a number of life-historyExpand

Demographic variation and population viability in Gentianella campestris: effects of grassland management and environmental stochasticity
Summary 1  Transition matrix models were used to evaluate the effects of environmental stochasticity and four different methods of grassland management on dynamics and viability of a populationExpand

Relationships between population and habitat characteristics and reproduction of the rare Gentiana pneumonanthe L.
We investigated the relationships among a number of population and site characteristics and the ovule and seed production and seed set in 17 populations of the rare, self-compatible,Expand

Does the presence of ant nests matter for oviposition to a specialized myrmecophilous Maculinea butterfly?
More than 50% of the lycaenid butterflies have an ant–associated lifestyle (myrmecophily) which may vary from coexistence to specific mutualistic or even parasitic interactions. Ant–relatedExpand

Reproductive success and clonal genetic structure of the rareArnica montana (Compositae) in The Netherlands
In a medium-sized population ofArnica montana, a threatened species in The Netherlands, the breeding system, reproductive success and genetic clonal structure were studied. Pollination experimentsExpand
