It has long been clear that interbreeding between domesticated and wild Atlantic salmon can lead to negative fitness consequences for native populations. Few studies, however, have examined these at critical early life stages, particularly in the context of distinct geographical ancestral relationships among populations as well domestication selection. In Newfoundland (NF), Canada, while majori...

in order to study the tolerance level of different wild barley (hordeum spontaneum) populations to clodinafop propargyl (topic®), a pot dose response experiment was conducted in a completely randomized design with three replications at ferdowsi university of mashhad greenhouse in 2009. cultivared barley (hordeum vulgare) and three wild barley populations (shiraz, boshroyeh, and torogh) were stu...

Truncated and mutant forms ofp53 affect life span in Drosophila, nematodes and mice, however the role of wild-type p53 in aging remains unclear. Here conditional over-expression of both wild-type and mutant p53 transgenes indicated that, in adult flies, p53 limits life span in females but favors life span in males. In contrast, during larval development, moderate over-expression of p53 produced...

trichinellosis is both of veterinary and medical importance in countries where pig breeding and pork consumption exists. in iran, people are forbidden to consume pork because of the religious regulations. therefore, there have not been any human cases over the past decades except a doubtful case based on serological test. although there are some sylvatic trichinellosis in wild life in different...

A greenhouse study was conducted to investigate the effects of nitrogen (N) on wild barley (Hordeum spontaneum Koch) interference with winter wheat (Triticum aestivum var. Pishtaz) by an additive series experiment. The experiment was conducted in a split plot design with 3 replications. Wheat plant height losses were on average 30, 10, and 10% in a wild barley density of 16 plants per pot with ...

To study the effects of applied nitrogen levels and wild mustard densities on the growth of wheat and wild mustard, a field experiment was conducted at Re-search and Experimental Field of Islamic Azad University of Ahvaz-Iran. The effects of three nitrogen levels namely 90, 150 and 210 kg.ha-1 and four wild mustard densities such as 0, 5, 10 and 15 plants.m-2 were evaluated in split plot arrang...

conclusions findings of the study demonstrated that the t. gondii infection is common in wild boars in southwest iran and could represent a significant health risk for animals, hunters, and local residents who may consume wild boar meat. results anti-t. gondii antibodies were detected in sera of 4 out of the 25 (16%) wild boars. there was no gender or age-related differences in seroprevalence o...

a two year field experiment was carried out to evaluate the competitive effects of wild mustard densities growing with rapeseed (cultivar talaye) under different nitrogen rates. treatments were wild mustard densities (0, 10, 20, 30, and 40 plant m-2) and nitrogen (n) rates (0, 50, 100, 150, and 200 kg n ha-1). the factorial set of treatments was arranged into a randomized complete block design ...
