استفاده از جوامع گیاهی توسط آهوی ایرانی(Gazella subgutturosa)در پناهگاه حیات وحش موته
Population of Persian gazelle has been declining in recent decades and as a result, this species was added to the IUCN list of threatened species in 2006. However, there is paucity of ecological data about this species within its range. Mooteh Wildlife Refuge is one of the best habitats of Persian gazelle in Iran where one of the biggest populations of this species live. Habitat selection by th...

متن کاملGenetic adaptation to captivity can occur in a single generation.
Captive breeding programs are widely used for the conservation and restoration of threatened and endangered species. Nevertheless, captive-born individuals frequently have reduced fitness when reintroduced into the wild. The mechanism for these fitness declines has remained elusive, but hypotheses include environmental effects of captive rearing, inbreeding among close relatives, relaxed natura...
متن کاملEstimates of direct and indirect effects for early juvenile survival in captive populations maintained for conservation purposes: the case of Cuvier's gazelle
Together with the avoidance of any negative impact of inbreeding, preservation of genetic variability for life-history traits that could undergo future selective pressure is a major issue in endangered species management programmes. However, most of these programmes ignore that, apart from the direct action of genes on such traits, parents, as contributors of offspring environment, can influenc...
متن کاملA review of artificial gynogenesis in the Caspian Sea sturgeons
In sturgeon, female-sex rearing is economical and gynogenesis induction is one of the ways to achieve it. In gynogenesis, an egg develops without the genetic influence of the male, or on the other words, it is a method of reproduction in which the offspring are formed exclusively from the genetic information of the mother. In this technique, the sperm used must be genetically inactivated. Rays ...
