Museomics Deciphers the Phylogeographic Differentiation and Conservation Status of a Montane Pheasant

open access: yesIntegrative 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 ...

Population Viability Analysis to Inform Reintroduction Decisions for a Group‐Living Primate, the Barbary Macaque

open access: yesAnimal Conservation, EarlyView.
We developed a population viability analysis to inform reintroduction strategies for the endangered Barbary macaque (Macaca sylvanus), incorporating age‐specific vital rates, release costs on survival and reproduction, environmental and demographic stochasticity, and catastrophic events.

Venetian local corn (Zea mays L.) germplasm: Disclosing the genetic anatomy of old landraces suited for typical cornmeal mush production. [PDF]

open access: yes, 2017
Due to growing concern for the genetic erosion of local varieties, four of the main corn landraces historically grown in Veneto (Italy) \u2014 Sponcio, Marano, Biancoperla and Rosso Piave \u2014 were characterized in this work.

Inbreeding Depression in Two Mimulus Taxa Measured by Multigenerational Changes in the Inbreeding Coefficient [PDF]

open access: yesEvolution, 1993
In mixed-mating plant populations, one can estimate the relative fitness of selfed progeny w by measuring the inbreeding coefficient F and selfing rate s of adults of one generation, together with F of adults in the following generation (after selection).

Parental Age, Inbreeding and Incubation Method Influence Extremely Low Hatching Success in the Ex‐Situ Population of the Extinct in the Wild Sihek

open access: yesAnimal Conservation, EarlyView.
Reproductive success rates are a key parameter determining the recovery potential of ex‐situ managed threatened species, with high rates often being required to produce offspring for wild releases while ensuring ex situ population viability. Here, we quantify reproductive success rates in the Extinct in the Wild sihek (Guam kingfisher) and find ...

Reduction of inbreeding in commercial females by rotational mating with several sire lines

open access: yesGenetics Selection Evolution, 2004
A mating system to reduce the inbreeding of commercial females in the lower level was examined theoretically, assuming a hierarchical breed structure, in which favorable genes are accumulated in the upper level by artificial selection and the achieved ...

Inbreeding in the coffee berry borer, Hypothenemus hampei (Coleoptera : Scolytidae) estimated from endosulfan resistance phenotype frequencies [PDF]

open access: yes, 1996
An estimate of the inbreeding coefficient, Fis, of the coffee berry borer, #Hypothenemus hampei$ Ferrari, was calculated from genotype frequencies of endosulfan resistance in beetles collected from berries in 41 fields on the East Coast of New Caledonia.

Microhaplotype Methods Enable Relationship Inference in a Bottlenecked Mammalian Species

open access: yesAnimal Conservation, EarlyView.
Northern elephant seals (Mirounga angustirostris) are among the most genetically depauperate mammals in the world. A near‐total population bottleneck in the 19th century, coupled with the breeding system of extreme polygyny, has challenged efforts to estimate individual reproductive success with genetic methods.

EFFECT OF INBREEDING ON SOME PERFORMANCE TRAITS IN SAHIWAL CATTLE

open access: yesPakistan Veterinary Journal, 2001
Pedigree, breeding and performance records of a purebred Sahiwal herd maintained at Livestock Experiment Station, Jahangirabad, Khanewal during the period 1939-97 were utilised for the present study. The effect of inbreeding on various performance traits
