in this study, 100 moghani sheep from breeding station located in jaafarabad, moghan were genotyped for exon 1 of igf-i gene, using pcr-sscp. different band patterns were obtained in this site gene that was studied. based on sscp patterns, three genotypes bc, bd and bb obtained with frequencies of 65%, 26% and 9%, respectively. the genotype frequencies had a significant deviation from hwe. in a...
The aim of present experiment was to investigate the feeding value of wild pistachio leaf (khinjuk leaf, KL) for Arabi sheep. The digestibility and fermentation of diets containing different amounts of khinjuk (0, 5, 10, 15, 20, 25 and 30%) were measured. Then, the effect of presence of KL in the diet and its tannin content on the digestibility of alfalfa hay (Alfa), wheat straw (WS) and soybea...
Land-use intensification and loss of semi-natural habitats have induced a severe decline of bee diversity in agricultural landscapes. Semi-natural habitats like calcareous grasslands are among the most important bee habitats in central Europe, but they are threatened by decreasing habitat area and quality, and by homogenization of the surrounding landscape affecting both landscape composition a...
Prior to European settlement in western North America, bighorn sheep (Ovis canadensis) were more widespread and abundant than they are today (Buechner 1960). The species arrived via the Bering land bridge approximately 70-100,000 years before the present (YBP) (Kurten and Anderson 1980) and slowly spread to occupy most mountainous regions of western North America from southern British Columbia ...
Moths are abundant and ubiquitous in vegetated terrestrial environments and are pollinators, important herbivores of wild plants, and food for birds, bats and rodents. In recent years, many once abundant and widespread species have shown sharp declines that have been cited by some as indicative of a widespread insect biodiversity crisis. Likely causes of these declines include agricultural inte...
