Although the examination of latitudinal gradients of species richness is common, little attention has been devoted to other components of biodiversity such as phenetic diversity. Because the phenotype reflects aspects of an organism’s environment, ecological relationships and evolutionary history, measures of phenetic diversity likely provide complimentary information to that of species richnes...

Phenelic clustering, the farming of hierarchical nonoverlapping groups strictly according to degree of similarity, has serious shcrrtcomings as it is commonly used in biology. When used as a method for estimatingphylogeny, phenetic clustering rests on a questionable assumption of correspondence between similarity and recency of common ancestry. This compromises its ability to reconstruct the co...

Molecular profiling experiments have become standard in current wet-lab practices. Classically, enrichment analysis has been used to identify biological functions related to these experimental results. Combining molecular profiling results with the wealth of currently available interactomics data, however, offers the opportunity to identify the molecular mechanism behind an observed molecular p...

نوزده جمعیت متعلق به دو گونه atropa belladonna و a. acuminata مورد بررسی فنتیکی قرار گرفتند. تجزیه خوشه ای و رسته بندی جمعیت ها براساس دو مولفه اول حاصل از تجزیه به مولفه های اصلی وجود دو گونه را تایید نمود. جمعیت های a. belladonna تفاوت های بسیاری را در بعضی از صفات ریختی نشان دادند. روش های آماری چند متغیره، علاوه بر صفاتی که در کلید شناسایی این گونه ها استفاده می شوند، صفات ریختی جدیدی را بر...

a phenetic analysis is presented using sahn clustering (upgma, simple matching coefficient). the resulting phenetic analysis is compared with the classification of oxytropis as suggested by bunge [2] and vassilczenko [ll]. the results partly correspond with bungean classification and suggest that there are basically four sections (mesogaea, oxytropis, janthina, eumorphu) which can be grouped un...

Two bacterial strains, PC-142 and PC-147(T), isolated from poultry litter compost, were characterized with respect to their phenetic and phylogenetic characteristics. The isolates were endospore-forming rods that were reddish in colour after Gram staining. They were catalase- and oxidase-positive, were able to degrade starch and gelatin and grew at 15-40 degrees C and pH 5.5-10.0. The predomina...
