Turkey is being a bridge between Europe and Asia and it provides the natural pathway for the spread of species between these continents. The Beydağları Mountains and its surroundings (Antalya) host many Asian, European and Mediterranean faunal and floral elements and the location, which is considered as one of the most important faunal areas in Turkey especially for larger mammals. The study is the first systematic survey of the carnivores in the region which is based on photo trapping. The cameras were set at 45 locations for 2055 trap days between 2005–2009 over the area 294 km2 at the altitude 1200–2000 m a.s.l. Most of the species and their individual abundance were recorded in maquis habitat type followed by red pine forest, mixed (red pine and maquis), and cedar forest respectively. The wild animals that were captured included five mammalian carnivore species (red fox Vulpes vulpes, badger Meles meles, stone marten Martes foina, gray wolf Canis lupus and caracal Caracal caracal) and also wild boar Sus scrofa, fallow deer Dama dama and hare Lepus europaeus. Photo trapping activity was mostly recorded between 21:00 and 03:00 hours. Wild terrestrial carnivores occur at low densities in the study area (1.73 for caracal and 0.9 for wolf ind.100 km-2) while the most widespread larger mammal was the wild boar (188 ind.100 km-2). The small fallow deer population was mainly confined in a large (4.2 km2) fenced enclosure and its size was accessed by direct drive count. The results support the hypothesis that Beydağları Mountains having the Asian, European and Mediterranean mammals makes the Anatolian Peninsula being a bridge between Europe and Asia. Caracal density was lower than the Datca population in the southern part of Anatolia. This may be consequence of higher human activities in the Beydağları Mts. Human activities in the Beydağları Mts. Should be reduced for sensitive animals to human activities like caracal and wolf and the illegal hunting should be strictly prohibited in the area for viability of the large mammals of Beydağları Mts.

Natural populations of many species are increasingly impacted by human activities. Perturbations are particularly pronunced for large ungulates due in part to sport and commercial harvest, to reductions and fragmentation of native habitat, and as the result of reintroductions. These perturbations affect population size, sex and age composition, and population breeding structure, and as a consequence affect the levels and partitioning of genetic variation. Three case histories highlighting long-term ecological genetic research on mule deer Odocoileus hemionus (Rafinesque, 1817), white-tailed deer O. virginianus (Zimmermann, 1780), and Alpine ibex Capra i. ibex Linnaeus, 1758 are presented. Joint examinations of population ecological and genetic data from several populations of each species reveal: (1) that populations are not in genetic equilibrium, but that allele frequencies and heterozygosity change dramatically over time and among cohorts produced in successive years, (2) populations are genetically structured over short and large geographic distances reflecting local breeding structure and patterns of gene flow, respectively; however, this structure is quite dynamic over time, due in part to population exploitation, and (3) restocking programs are often undertaken with small numbers of founding individuals resulting in dramatic declines in levels of genetic variability and increasing levels of genetic differentiation among populations due to genetic drift. Genetic characteristics have and will continue to provide valuable indirect sources of information relating enviromental and human perturbations to changes in population processes.
