Challenges Of In Situ Conservation Of Crop Wild Relatives, Vernon Hilton Heywood
Challenges Of In Situ Conservation Of Crop Wild Relatives, Vernon Hilton Heywood
Turkish Journal of Botany
Crop wild relatives (CWRs) will gain in importance as changing climates put both traditional and advanced cultivars under increasing stress, leading to a need for plant breeding to produce new varieties able to grow under the new climate regimes. Traditionally, the approach to the conservation of CWRs has been ex situ - the collection and maintenance of seed accessions in national, regional, and international germplasm banks, supplemented by field genebanks for species with recalcitrant seeds. More recently the need to maintain CWRs in their natural habitats (in situ) has been advocated. This is very different from on-farm conservation of traditional …

Several countries are now aiming at ex-situ and in-situ programmes for the protection and conservation of plant species through the Global Strategy for Plant Conservation targets (GSPC). Is it possible to achieve these targets in rapidly developing countries where the usage of land for urban expansion and agriculture to support basic human needs holds priority? How can conservation and development be sustainable? I take examples from a rapidly developing country in the Arabian Peninsula to show …
Biology Of The Central Desert Of Oman, Shahina A. Ghazanfar
Biology Of The Central Desert Of Oman, Shahina A. Ghazanfar
Turkish Journal of Botany
A biological survey of the central desert of Oman was done using long distance transects. Vegetation was sparse and consisted of 200+ plant species, 22 species of mammals, 17 species of reptiles and amphibians, and more than 50 species of birds (migratory and resident). Three main vegetation types were identified based on ground substrate and the dominance of species. These were communities with Acacia Willd., Zygophyllum L., and open woodlands of Prosopis cineraria (L.) Druce. Over-grazing and development in the central desert has led to concerns over the conservation of the desert ecosystem in Oman.
