El Batolito de Pataz del Carbonífero (Missisipiano), datado entre los 329 – 347 Ma (Haeberlin et al., 2004), tiene aproximadamente 160 km largo (N30°O) y un ancho 2.5 a 5 Km actualmente reconocidos. intrusivo está constituido por más una facies plutónica; granito granodiorita otra tonalita - diorita, siendo la primera favorable para el emplazamiento desarrollo las vetas tipo orogénico con conte...

identifying and selecting superior genotypes in native germplasm is one method for breeding fruit trees. five different ecotypes of jujube (ziziphus jujuba mill.) were collected from different regions of isfahan province, iran, for evaluation of their morphological and pomological traits during 2011-13. results showed that quantitative traits were more significant within ecotypes. ‘‘najafabad’ ...

seed dormancy has a critical role in ecological adaptation of wild plant species such as hordeum spontaneum, a wild relative of barley. in this study, 192 ecotypes of hordeum spontaneum maintained in national plant gene bank of iran (npgbi) originating from different climatic zones of the country were evaluated. morphological, phenological and physiological traits were recorded in the field. af...

We have investigated microbial mats of alkaline siliceous hot springs in Yellowstone National Park as natural model communities to learn how microbial populations group into species-like fundamental units. Here, we bring together empirical patterns of the distribution of molecular variation in predominant mat cyanobacterial populations, theory-based modelling of how to demarcate phylogenetic cl...

The fatty-acyl composition of the seed oil was determined for 100 ecotypes of Arabidopsis thaliana. Despite coming from diverse geographical locations, seed fatty-acyl profiles of all ecotypes were remarkably similar. They contained identical fatty acids, including the characteristic C20 and C22 very-long-chain fatty acids (VLCFAs). The total proportions of seed VLCFA varied between 22% and 35%...

The aim of this study was to investigate the chemical composition three maca (Lepidium meyenii Walp.) ecotypes (yellow, black, and red) their in vitro fermentation characteristics antioxidant effects on cow rumen liquor. were added a total mixed ratio (TMR) different doses (0, 150, 300 mg/g) incubated under anaerobic conditions for 120 h. Methane production recorded after 24 h incubation. Antio...
