Phylogenetic Relationships Between Malcolmia, Strigosella, Zuvanda, And Some Closely Related Genera (Brassicaceae) From Turkey Revealed By Inter-Simple Sequence Repeat Amplification, Beki̇r Doğan, Murat Ünal, Fevzi̇ Özgökçe, Esra Marti̇n, Ayla Kaya
Turkish Journal of Botany
The genus Malcolmia W.T.Aiton is taxonomically problematic, and some of its species have recently been transferred to the genera Strigosella Boiss. and Zuvanda Dvorák. Three species of this genus are native to Turkey. The revision studies based on molecular data, which were collected in the past few years, display the phylogenetic relations and the systematic positions of the taxa more reliably and apparently. Thus taxonomic problems of species are resolved through DNA-based molecular analyses, which are not affected by environmental factors compared to phenotypic studies. In the present study, the amplifications of the DNA fragments were carried out using ISSR …

Rare And Endemic Species: Why Are They Prone To Extinction?, Kani̇ Işik
Rare And Endemic Species: Why Are They Prone To Extinction?, Kani̇ Işik
Turkish Journal of Botany
A species is considered to be "rare" if it exhibits any one of the following attributes: (1) naturally occurs in a narrow geographical area, (2) occupies only one or a few specialised habitats, (3) forms only small population(s) in its range. An "endemic" species, however, grows naturally in a single geographical area, the size of which could be either narrow or relatively large. Not all endemic species are rare, just as not all rare species must necessarily be endemic. Many rare and/or endemic species exhibit one or more of the following attributes which make them especially prone to extinction: (1) …

Strategies For Conserving Forest Genetic Resources In The Face Of Climate Change, John Bradley St.Clair, Glenn Thomas Howe
Strategies For Conserving Forest Genetic Resources In The Face Of Climate Change, John Bradley St.Clair, Glenn Thomas Howe
Turkish Journal of Botany
Conservation of genetic diversity is important for continued evolution of populations to new environments, as well as continued availability of traits of interest in genetic improvement programs. Rapidly changing climates present new threats to the conservation of forest genetic resources. We can no longer assume that in situ reserves will continue to preserve existing genetic diversity. Management of reserves should become more active. In some reserves, existing genetic diversity should be preserved by creating stands that are more resistant to threats using silvicultural treatments such as thinning and prescribed burning. In other reserves, natural selection and adaptation to changed environments …
