Nest-Site Selection, Breeding Success, And Diet Of White-Tailed Eagles(Haliaeetus Albicilla) In The Danube Delta, Romania, Attila D. Sandor, Vasile Alexe, Mihai Marinov, Alexandru Doroşencu, Cristian Domsa, Botond J. Kiss

Turkish Journal of Zoology

The white-tailed eagle is a flagship species of wetland conservation throughout Europe; thus, general conservation efforts targeting this species can provide effective protection for most species occupying similar habitats. The species' breeding ecology is well known in northern and western Europe; however, the locally important Danube Delta population has scarcely been studied. Here, the eagles primarily select tall trees for nesting (mostly willow and white poplar), with most nests built above 15 m. The breeding population is geographically concentrated in the northern and northwestern parts of the delta, most probably because of available nest sites in less-disturbed areas. The population …

In the first experiment, HM 1, Pigeon Point, CFRA1267 (F. chiloensis subsp. pacifica), and CA1541 (F. chiloensis subsp. chiloensis) were tested with various Fe concentrations (0%, 10%, 15%, 25%, 50%, 65%, …

Usefulness Of Short Sequence Repeat Markers In Goat Genetic Diversity Studies On The Asian And African Continents, Faiz M.M.T. Marikar, Muneeb M. Mustafa

Turkish Journal of Veterinary & Animal Sciences

Goat genetic diversity studies are very important since extinction of germ plasma is increasing very rapidly. The African and Asian continents are the hotspots for indigenous animals with fewer genetic manipulations. Conservation studies using molecular markers have the capability to validate the real status of the animals. The use of molecular markers has revolutionized studies of genetic diversity. Even though a number of markers are used for these types of studies, short sequence repeats are in the forefront due to their superior features such as high variability, high mutation rate, large number, distribution throughout the genome, codominant inheritance, and neutrality …
