The objective of the present study was to detect polymorphism in follicle stimulating hormone receptor (FSHR) and beta subunit of follicle stimulating hormone (FSHβ) genes and their relation to litter size and body weight trait in Baluchi, Iran black and Arman sheep breeds. PCR-RFLP technique using ACCI and HinfI enzyme treatments employed to detection of polymorphism in FSHβ marker site but de...

Based on mitochondrial DNA (mtDNA) cytochrome b (cyt b) gene was partially sequenced and analysed in order to investigate genetic diversity between domestic sheep (Ovis aries) synthetic line BCP n=16 and wild sheep mouflon (Ovis musimon) n=24 from the Sowie Mountains in Poland. All 18 haplotypes were observed which formed two distinct clades in O. aries BCP synthetic line and three clades in mo...

Australia's wild dogs include dingoes, introduced around 4000 years ago, feral domestic dogs and hybrids between the two. They are widely distributed throughout Australia. Predation and harassment of stock by wild dogs causes millions of dollars worth of losses to Australian sheep, cattle and goat producers each year. There are also opportunity costs in areas where sheep are not grazed because ...

When domesticated species are not reproductively isolated from their wild relatives, the opportunity arises for artificially selected variants to be re-introduced into the wild. However, the evolutionary consequences of introgression of domesticated genes back into the wild are poorly understood. By combining high-throughput genotyping with 25 years of long-term ecological field data, we descri...

carnivores play great ecological roles in ecosystems because of placing on top of the food pyramid. food habits of large carnivores are associated with important ecological features such as spatial pattern, movement, habitat selection, social structure, geographical distribution and reproductive success. accordingly, in this study was used scat analysis to determine the diet of persian leopards...

Archaeozoological evidence indicates that sheep were first domesticated in the Fertile Crescent. To search for DNA sequence diversity arising from previously undetected domestication events, this survey examined nine breeds of sheep from modern-day Turkey and Israel. A total of 2027 bp of mitochondrial DNA (mtDNA) sequence from 197 sheep revealed a total of 85 haplotypes and a high level of gen...

Utilization of fecundity genes such as GDF9 and BMP15 can help improve reproductive traits in sheep breeding programme. To evaluate effects of missense mutations on protein function, the polymorphisms of GDF9 and BMP15 genes were screened in twelve mehraban sheep using DNA sequencing, followed by protein structure modeling. Six single nucleotide polymorphism (SNPs) known as FecG mutations (G1-G...

Understanding the factors shaping the dynamics of carnivore-livestock conflicts is vital to facilitate large carnivore conservation in multi-use landscapes. We investigated how the density of their main wild prey, roe deer Capreolus capreolus, modulates individual Eurasian lynx Lynx lynx kill rates on free-ranging domestic sheep Ovis aries across a range of sheep and roe deer densities. Lynx ki...

The use of noninvasive genetic sampling to identify the sex of wild animals is an extremely valuable and important tool in molecular ecology and wildlife conservation. Sex determination using the amelogenin gene has been conducted in many species because only a single pair of primers is required to amplify both X- and Y-linked alleles. However, this method has not been used in field research wi...

the objective of the present study was to detect polymorphism in follicle stimulating hormone receptor (fshr) and beta subunit of follicle stimulating hormone (fshβ) genes and their relation to litter size and body weight trait in baluchi, iran black and arman sheep breeds. pcr-rflp technique using acci and hinfi enzyme treatments employed to detection of polymorphism in fshβ marker site but de...
