Crocus antalyensis B. Mathew is a bulbous plant endemic to Turkey. It is morphologically variable within the western part of Anatolia. Amplified fragment length polymorphism (AFLP) marker system was used to detect genetic variation among the Crocus taxa. Twenty-two primer combinations were used to screen for polymorphism among the samples. Genetic variation ranged from .44 to .69. We demonstrated the efficiency of the AFLP marker system for discriminating between individual C. antalyensis specimens. A high level of genetic variation was present among C. antalyensis specimens collected from different locations in Turkey. We also observed that C. antalyensis subspp. are genetically distinct from their relative Crocus flavus Haw. subsp. dissectus Baytop & B. Mathew. A new subspecies of C. antalyensis B. Mathew from southern Turkey is described. It is characterized by striped outer perianth segments, waist-shaped flowers, and glabrous throat of the perianth. A composite image of the new subspecies is presented.

The West Asian stripe-necked terrapin Mauremys caspica is widespread throughout the Middle East—a region for which only few phylogeographic studies are available. Due to landscape alteration, pollution and intensification of water management, M. caspica is increasingly threatened. However, gene...

Differentiation at mitochondrial and nuclear loci between the blesbok (Damaliscus pygargusphillipsi) and bontebok (D. p.pygargus): implicat
Damaliscus pygargus is an endemic species in South Africa belonging to the contemporary antelope tribe Alcelaphine. The species has been subdivided into two subspecies based upon phenotypic differences and historical geographic isolation. We found D. p. pygargus (bontebok) and D. p. phillipsi (bl...
