Estimating the fixation probability of a beneficial mutation has a rich history in theoretical population genetics. Typically, to attain mathematical tractability, we assume that generation times are fixed, while the number of offspring per individual is stochastic. However, fixation probabilities are extremely sensitive to these assumptions regarding life history. In this article, we compute t...

ovis orientalis isphahanica has a restricted geographical range and is listed as vulnerable by iucn. however, there is not enough data on habitat associations of this taxon to be used as a base for conservation programmes. use of vegetation communities by isfahan mouflon in mouteh wildlife refuge was studied over a one-year period. habitat use was related to vegetation communities and habitat v...

As supplements to classical chemical insecticides, two approaches to develop recombinant baculovirus insecticides are described. In one approach an insect-specific toxin is expressed leading to a dramatic reduction in time to death. In the second approach an insect juvenile hormone esterase is expressed which leads to a reduction in feeding. Modifications of the wildtype esterase led to viruses...

In order to study the effects of wild mustard competition and different levels of nitrogen on effective traits of wheat yield, this research was conducted in Ahvaz, south west of Iran. The study was consisted of a split plot experiment, on the basis of Randomized Complete Blocks Design with three replications. Different levels of nitrogen (90, 150 and 210 kgN.ha-1) were assigned in the main plo...

The p53 protein function is essential for the maintenance of the nontumorigenic cell phenotype. Pancreatic tumor cells show a very high frequency of p53 mutation. To determine if restoration of wild type p53 function can be used to eliminate the tumorigenic phenotype in these cells, pancreatic tumor cell lines, PANC-1 and HTB80, differing in p53 status were stably transfected with exogenous wil...

this study was conducted at the gorgan university of agricultural sciences and natural resources farm, iran, golestan province with about 600 mm annual rainfall in order to evaluate the effect of different sowing dates on azivash (corchorusolitorius) seed quality, using a randomized complete block design with three replications on 2013. treatments were four sowing dates such as may 5, jun 5, ju...
