The Future of Ex Situ Conservation

2000
It is with great trepidation that we attempt in this final chapter to address what we believe may be the major issues that Ex Situ conservationists will be forced to confront and attempt to resolve in the next ten to fifty years, let alone the whole of the new millennium.

Captive breeding and ex situ conservation

2013
Abstract Primates began the arduous journey out of their native countries and into captive collections in the late nineteenth century. However, their survival was severely limited by a lack of natural history knowledge and husbandry requirements. In the decades to follow, primate survivorship and propagation in zoos greatly increased. By

Ex Situ Conservation – Case Study Croatia

2018
Genetic diversity of Croatian forest tree species is being conserved using the ex situ static method. Clonal seed orchards are the nucleus of forest genetic resource conservation, since the relationship between the size of the population and the percentage of preserved heterozygocity is thus reduced to minimal loss of total additive genetic variability.

Ex Situ Conservation of Grain Legumes

2001
The major food legumes that originated in the Mediterranean and that are important in this region include chickpea (Cicer arietinum L.), lentil (Lens culinaris L.), and faba bean (Viciafaba L.). Lentil is an ancient cool-season field legume that has been traditionally grown in the Middle East, the Indian subcontinent, Ethiopia, North Africa, and to a ...

Ex situ conservation of plant germplasm using biotechnology

World Journal of Microbiology & Biotechnology, 1995
Conservation of plant genetic resources attracts more and more public interest as the only way to guarantee adequate food supplies for future human generations. However, the conservation and subsequent use of such resources are complicated by cultural, economical, technical and political issues.

Crambe tataria: actions for ex situ conservation

Biodiversity and Conservation, 2010
In vitro micropropagation by direct organogenesis and somatic embryogenesis via callus was developed for Crambe tataria (Brassicaceae). C. tataria is an endemic species of the Pontic-Pannonic region, but it is also present in Italy, where it is localized in Friuli on a characteristic grassland formation, called “magredi”. C.

Ex Situ Conservation of Forage Legumes

2001
This chapter analyses progress and the current status of ex situ conservation of 739 species of 27 genera of forage legumes in relation to their natural distribution. Analysis is based on passport data of individual accessions. As such, the scope of the chapter is restricted to those collections for which the authors have been granted access to ...

[Genetic risks in plant ex situ conservation].

Yi chuan = Hereditas, 2006
Conserving genetic diversity of rare and endangered species and their evolutionary potential is one of the long-term goals of ex-situ conservation. Some potential genetic risks in ex-situ conservation in botanical gardens are presented. The preserved species may lack genetic representativity because of poor sampling.
