Ex situ conservation of bryophytes: case studies

Marko Sabovljevic (Belgrad): Bryophytes are often overlooked in conservation initiatives despite their presence in most terrestrial habitats and being major contributors to the functioning and biodiversity in almost all ecosystems apart from the marin one. When the populations of the target species are very small or threatened biotechnological procesess are needed with aim to establish good pool of material. This is the first step in ex situ conservation, prior to acclimatization or reintroduction/introduction. However, there are many problems in achieving a good developed pool and often species specific. The cases of mosses and liverowirts studied for ex situ purposes will be presented with achievment, problems and further plans. Special emphasis will be given to some European rare species such as: Bruchia vogesiaca, Campylopus oerstedianus, Molendoa hornschuchiana, Entosthodon hungaricus, Riella helicophylla and Hennediella heimii.
