The Future of Ex Situ Conservation
2000It 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.

Ex Situ Conservation of Forage Legumes
2001This 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 ...

Preparing To Collect for Ex Situ Conservation
2000A conservation project will most commonly be commissioned by an institute or organisation and will usually take the form of a statement. It will outline the objectives, breadth of the target taxon and target area to be investigated, as well as outlining any specific requirements, such as whether the conservation should focus on in situ or Ex Situ ...

Captive breeding and ex situ conservation
2013Abstract 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

Preserving Population Allele Frequencies in Ex Situ Conservation Programs
Conservation Biology, 2008Abstract: Optimization of contributions of parents to progeny by minimizing the average coancestry of the progeny is an effective strategy for maintaining genetic diversity in ex situ conservation programs, but its application on the basis of molecular markers has the negative collateral effect of homogenizing ...

Ex-situ conservation of marine microorganisms
Microorganisms flourish even in environments presumably incompatible with life. Inhabiting major biodiversity of life on Earth, they harbor novel metabolites and genes with broad-spectrum applications in agricultural, environmental, biotechnology, medicinal, and industrial sectors, also playing vital roles in biogeochemical cycles in all ecosystems.

Ex Situ Conservation Strategies in Litchi Germplasm
2017The delicious fruit Litchi chinensis is a commercially important heterozygous cross-pollinated fruit species of the world. To increase its production of this fruit, plant breeding is required. Henceforth, the conservation of its germplasm resources is an important step toward improvement of new cultivars resistant to abiotic and biotic stresses through
