Understanding the Past to Preserve the Future: Genomic Insights Into the Conservation Management of a Critically Endangered Waterbird.

To ensure the success of genetic rescue, we must minimise the potential negative effects of outbreeding depression that may arise from selecting source populations. The difficulty in assessing the likelihood of outbreeding depression has hindered its consideration in endangered species conservation. However, genomic research offers feasible indications.

[Long Sperm Storage in the Siberian Crane (Grus leucogeranus Pallas): Analysis of Paternity and Relatedness under Artificial Insemination].

Using ten microsatellite loci, paternity analysis has been conducted for 71 individuals of the Siberian crane (Grus leucogeranus Pallas) obtained under artificial insemination in Oka Crane Breeding Center in 2001–2014. The fathers of 39 chicks were the sires whose sperm was used for insemination directly before fertilized egg laying. Paternity of 23 fertilizations belonged to the sires whose sperm was used in the beginning or middle of insemination cycle.

[Offspring Sex Ratio in the Captive Population of Siberian Crane (Grus leucogeranus Pallas)].

The sex ratio of Siberian crane chicks (Grus leucogeranus Pallas) from the captive population ofthe Oka Crane Breeding Center was analyzed with the use of molecular sex marker EE0.6 in 2009-2014. We determined the sex of 84 birds bred from 12 dams by means of artificial insemination and natural breeding.

[Microsatellite data verify low genetic differentiation between western and eastern subspecies of the common crane Grusgrus L. (Gruidae, Aves)].

Using a set of 10 microsatellite loci (Gram-22, Gram-30, Gpa-12, Gpa-38, Gpa-39, Gj-M15, Gj-M34, Gj-4066, Gj-8077, Gj-2298) a high level of genetic variability (N(A) = 10.2, H(O) = = 0.684, H(E) = 0.

[Genetic diversity and relatedness in different generations of the Siberian crane (Grus leucogeranus Pallas) captive population].

Eight variable microsatellite loci were analyzed in terms of studying the genetic structure of different generations of a captive population of a rare endemic Russian species, the Siberian crane (Grus leucogeranus Pallas). It was shown that the founding population of natural origin (15 birds) is characterized by high genetic diversity (N(A) = 6.625, H(O) = 0.
