Ex situ cultivation in botanic gardens could be one possibility to preserve plant species
diversity and genetic variation. However, old ex situ populations are often sparsely …

Habitat fragmentation can lead to a decline of genetic diversity, a potential risk for the
survival of natural populations. Fragmented populations can become highly differentiated …

Hybridization has played a major role during the evolution of angiosperms, mediating both
gene flow between already distinct species and the formation of new species. Newly formed …

In Belgium, at the western border of its continental distribution range, the perennial herb S.
nutans has evolved two parapatric ecotypes (calcicolous or silicicolous), which show …

Population fragmentation is often correlated with loss of genetic diversity and reduced
fitness. Obligate out-crossing (dioecy) is expected to enhance genetic diversity, reduce …

Many botanic gardens keep ex situ collections of rare species to prevent their extinction and
to enable their reintroduction into the wild. A potential problem with ex situ collections is that …

Worldwide, botanical gardens cultivate around 80,000 taxa, corresponding to approximately
one‐quarter of all vascular plants. Most cultivated taxa are, however, held in a small number …

Conservation of imperiled plant species often requires ex situ (offsite) living collections.
Protocols for developing these collections most often emphasize sampling depth, but little is …

Premise of research. Ex situ plant conservation can be improved through genetic analysis.
One area of interest is the relative value of conserving smaller or larger populations and how …

Genetic factors influence the populationviability of rare species, yet the fitnessconsequences
of inbred and outbred progeny areseldom tested empirically in reintroductionstrategies …
