Integrative Zoology, EarlyView.Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities
Integrative Zoology, EarlyView.Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

Computing inbreeding coefficients accounting for unknown parents using pedigree-based metafounders
JDS CommunicationsMissing pedigrees result in underestimated numerator relationship and inbreeding coefficients in a closed population. Recursive algorithms have been proposed to derive nonzero inbreeding coefficients accounting for unknown parents but can be ...

EFFECT OF INBREEDING ON LOIN AND FAT DEPTH IN HUNGARIAN LANDRACE PIGS [PDF]
Poljoprivreda, 2007 Pedigree and field test data - collected between 1997-2005 - were analyzed in a group of 68062 Hungarian Landrace pigs. The analysed traits were loin depth (LD), fat depth1 (FD1) and fat depth2 (FD2).

Genomic Inbreeding and Relatedness in Wild Panda Populations.
PLoS ONE, 2016 Inbreeding and relatedness in wild panda populations are important parameters for panda conservation. Habitat loss and fragmentation are expected to increase inbreeding but the actual inbreeding levels in natural panda habitats were unknown.

The Outcomes of Selection in a Closed Herd on a Farm in Operation [PDF]
Asian-Australasian Journal of Animal Sciences, 2015 A herd of Berkshire pigs was established in 2003 and subjected to selection without introduction of any genetic resources until 2007. The complete pedigree, including 410 boars and 916 sows, as well as the records from 5,845 pigs and 822 litters were ...
