Allozyme variation in Ulmus species from France: analysis of differentiation

Allozyme Analysis for Assessing Genetic Variation in the Species Bactrocera Diversa and B. Zonata (diptera: Tephritidae)

Allozyme analysis was used to assess genetic variability in tephritid fruit fly Bactrocera diversa and B. zonata. In our experimental conditions, allozyme analysis at twelve enzyme loci scores twenty one putative alleles. The amount of mean observed heterozygosity (HO) was 0.22 and 0.28 and amount of mean expected heterozygosity (HE) was 0.28 and 0.37, in B. diversa and B. zonata, respectively....

analysis of power in the network society

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...

Further analysis of allozyme variation in the Northern Flicker, in comparison with mitochondrial DNA variation

Allozyme variation of Cyclobalanopsis championii (Fagaceae), a narrowly distributed species in southern Taiwan.

Allozyme genetic variability in five natural populations of Cyclobalanopsis championii (Fagaceae) in Taiwan was investigated using 12 loci from 9 enzyme systems. The average values of parameters describing within-population variation, expected heterozygosity (He = 0.151), the percentage of polymorphic loci per individual (P = 50%), the average number of alleles per locus (A = 1.7), effective nu...

Allozyme differentiation in five species of North American shrews (Soricidae: Mammalia)

Starch gel electrophoresis was used to investigate patterns of genetic variation in five species of shrews from southern Illinois, and western Kentucky and Tennessee. Four of the five species occur sympatrically. Twenty-eight presumptive loci were examined in the following species: pygmy shrew Sorex hoyi Baird, southeastern shrew Sorex longirostris, northern short-tailed shrew Blarina brevicaud...
