Reproductive Success Of The Rare Endemic Orchis Galilaea (Orchidaceae) In Lebanon, Nisrine Machaka Houri, Mohammad Souheil Al-Zein, Duncan Brian Westbury, Salma Nashabe Talhouk
Reproductive Success Of The Rare Endemic Orchis Galilaea (Orchidaceae) In Lebanon, Nisrine Machaka Houri, Mohammad Souheil Al-Zein, Duncan Brian Westbury, Salma Nashabe Talhouk
Turkish Journal of Botany
The biology and ecology of Orchis galilaea Schltr., a species endemic to Lebanon, Palestine, and Jordan, is poorly studied, a fact that hinders present and future management and conservation efforts concerning this species. In this paper, we report findings of a field investigation that assessed the impact of altitude, population density, and plant size on the reproductive success of O. galilaea. The results revealed that plant size and population density were significantly correlated with reproductive success while altitude was not. This study is part of ongoing research on the ecological responses of O. galilaea and provides a baseline for understanding …

Reproductive Biology Studies Towards The Conservation Of Two Rare Species Of Colchic Flora, Arbutus Andrachne And Osmanthus Decorus, Nina Melia, Laura Gabedava, Tinatin Barblishvili, Lali Jgenti
Turkish Journal of Botany
Our study examines the structural peculiarities of the generative sphere at different phases of development, and the processes of pollination, fertilisation, and seed formation in 2 species of wild flora: Arbutus andrachne L. (Ericaceae), the eastern strawberry tree, and Osmanthus decorus (Boiss. & Balansa) Kasapligil (Oleaceae), Caucasian osmanthus. These Arcto-Tertiary plants are included in the Red Data Book of the Georgian SSR. As germinable seeds are the main factor determining species distribution and the complete transfer of genetic information, the aim of our research was to establish the self-regeneration capacity of the species under study and choose optimum conditions for …
Notes On The Sikkim Himalayan Rhododendrons: A Taxa Of Great Conservation Importance, Kaushal K. Singh
Notes On The Sikkim Himalayan Rhododendrons: A Taxa Of Great Conservation Importance, Kaushal K. Singh
Turkish Journal of Botany
Rhododendrons form dominating species all along the temperate, subalpine and alpine zones in the Sikkim Himalaya. Rhododendron L. is one of the largest genus of the Ericaceae family, occurring in the higher altitudes having ecological significance and economic importance in addition to its splendiferous flowers. It has aesthetic, sacred, aromatic, medicinal and fuelwood values. There are 36 species with 45 different forms (including subspecies and varieties) in the Sikkim Himalaya. Using IUCN guidelines for categorization eight species are being evaluated according to population characters. It has been observed recently that the rhododendrons of the region are under pressure, which are …

Propagation Of Endangered Thermopsis Turcica Tan, Vural & Küçüködük Using Conventional And In Vitro Techniques, Süleyman Cenkçi̇, Mehmet Temel, Mustafa Kargioğlu, Sergun Dayan
Turkish Journal of Biology
This report deals with the successful clonal propagation of endangered T. turcica using rhizome cuttings and epicotyl explants. Rhizome cuttings were treated with \alpha-naphthaleneacetic acid (NAA) or indole-3-butyric acid (IBA) before planting for vegetative multiplication. Rhizome cuttings pretreated with NAA (10 mg/L) were both rooted and sprouted (66.6 percent) after 100 days. Application of NAA induced callus and adventitious root formation in epicotyl explants and 6-benzyladenine (BA) induced production of microshoots. Low levels of NAA (0.5-1 \muM) together with BA promoted shoot initiation and development. The highest regeneration rate (86.6 percent), with a mean number of shoots (3.05) and a …
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 …
Conservation In Developing Countries, Shahina A. Ghazanfar
Conservation In Developing Countries, Shahina A. Ghazanfar
Turkish Journal of Botany
The Convention on Biological Diversity (CBD) set a number of targets to work towards by 2010 in order to aid conserve the world´s biodiversity. 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 …

Recommendations for implementing conservation measures and future bat research avenues in Jordan are highlighted.
The Status Of Birds In The Proposed Rum Wildlife Reserve, Southern Jordan, Michael Evans, Zuhair Sami Amr, Ratib M. Al-Oran
The Status Of Birds In The Proposed Rum Wildlife Reserve, Southern Jordan, Michael Evans, Zuhair Sami Amr, Ratib M. Al-Oran
Turkish Journal of Zoology
The Royal Society for the Conservation of Nature officially proposed the creation of the Rum Wildlife Reserve, in the extreme south of Jordan, in 1979. We present the first review of the birds of the proposed reserve and its environs, drawing upon published and unpublished records as well as a short field survey from June, 1996. A total of 142 species have been recorded, of which at least 34 species actually breed and another 14 probably do so. Most breeding species are (a) Saharo-Arabian desertic species, or (b) non-desertic species which have colonised the area due to the advent of …
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.

Taxonomy And Conservation Status Of Acantholimon Laxiflorum Boiss. Ex Bunge (Plumbaginaceae), Musa Doğan, Hayri̇ Duman, Gali̇p Akaydin
Taxonomy And Conservation Status Of Acantholimon Laxiflorum Boiss. Ex Bunge (Plumbaginaceae), Musa Doğan, Hayri̇ Duman, Gali̇p Akaydin
Turkish Journal of Botany
Acantholimon laxiflorum Boiss. ex Bunge (Plumbaginaceae), a local endemic species in Turkey, was subjected to taxonomic analysis in order to clarify its taxonomic status, because this species seems to have been wrongly treated and overlooked since it was first described by Boissier. The species is restricted to the east of Arsuz (C5 Hatay, Turkey) along dry riverbank, where it grows in rocky places on serpentine rocks. A full description and an illustration of the species are given, along with some additional information dealing with its ecology, phytogeography and conservation status.
