A general framework is presented to unify diverse models of natural selection. This framework is based on the Price Equation, with two additional steps. First, characters are described by their multiple regression on a set of predictor variables. The most common predictors in genetics are alleles and their interactions, but any predictor may be used. The second step is to describe fitness by mu...
سازند پابده در برش دره شهر شامل 260متر شیل، شیل آهکی، مارن و آهک می باشد. مطالعات انجام شده بر روی فرامینیفرهای پلانکتون منجر به شناسایی و ارائه تعداد 12 بیوزون شده است. این بیوزون ها عبارتند از: بیوزون شماره یک: parasubbotina pseudobulloides partial-range zone ، بیوزون شماره دو: subbotina triloculinoides partial-range zone، بیوزون شماره سه: morozovella angulata partial-range zone ، بیوزون شمار...
Despite being the objects of numerous macroevolutionary studies, many of the best represented constituents of the fossil record-including diverse examples such as foraminifera, brachiopods, and mollusks-have mineralized skeletons with limited discrete characteristics, making morphological phylogenies difficult to construct. In contrast to their paucity of phylogenetic characters, the mineralize...
abstract suitable seedling is one of the most important factors of onion growth and yield in transplanting method (tm). in order to investigation effects of different seedling size and age on marketable yield , biological yield, harvest index and some qualitative characters in onion an experiment was couducted at the agricultural research center of east azarbayjan in 2008. the factorial was con...
In order to evaluate the morphological and agronomic characteristics of 19 land races of onions and one foreign cultivar (Yellow Sweet Spanish), an experiment was conducted in 1998 at the Research Farm of the College of Agriculture, Isfahan University of Technology. Analysis of variance showed significant differences among genotypes for all of the morphological and agronomic traits. Dry weight ...
Changes in black tea quality were studied for three subsequent years and in different times of plucking (spring, summer and autumn) in the form of two leaves and a bud. Percentage of waste, total sensory scores, total soluble solid, caffeine, theaflavin, thearobigin, total color and brightness were evaluated in black tea. The data were analyzed in split plot design based on randomized complete ...
Root knot nematodes (Meloidogyne spp.) cause yield loss in all countries, of which, M. javanica, is the most widespread species in Iran. In order to identify M. javanica, 100 infected root and soil samples of root knot nematode were collected from different regions of Kerman province. After purification of populations and identification of M. javanica based on morphological and morphometerical ...
