The response of different feeding groups of staphylinid beetles to organic management, distance to perennial boundary and landscape context was studied in 42 paired organic and conventional winter wheat fields. Management effects were found to strongly depend on feeding group. While the activity-density of predators was higher in the conventional fields, both activity-density and species richne...
It is widely held that the dinosaurs were driven to near extinction because of the Chicxulub asteroid collision with the Earth about 65 million years ago (MA). Without doubt, dinosaur diversity in the fossil record after the collision was at most a percent of what it was prior to the collision. But whether the collision was the principal cause of the extinction is more difficult to assess. Here...
Stems of 4348 lianas from 12 subsampled 1 ha plots in Yasunı́, Ecuador represented more than 311 species of climbing woody plants. The plots (each 0.2 ha in area), which individually included up to 106 species among 314 stems, were established in the Huaorani Ethnic Reserve and Yasunı́ National Park and represent terra firme and floodplain habitats. Yasunı́ is one of the richest areas sampled for ...

بررسی تنوع ژنتیکی ژنوتیپهای بومی پیاز ایرانی در مقایسه با انواع خارجی چکیده: برنامه های اصلاحی گیاهان بر اساس تنوع و انتخاب صفات برتر کمی و کیفی صورت می گیرد. لذا، ارزیابی تنوع ژنتیکی، اولین مرحله در برنامه های اصلاحی است. در این راستا، استفاده از روش های جدید مطالعهی تنوع ژنتیکی ضروری به نظر می رسد. در این بررسی تعیین تنوع ژنتیکی سیزده ژنوتیپ پیاز ایرانی در مقایسه با دو ژنوتیپ خارجی با است...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
In this term paper, diversity in management positions and organizational performance is analyzed using gender diversity as a mediating role. The analysis is done based on the review of related literature. An organization’s success and competitiveness depends upon its ability to embrace diversity and realize the benefits. The success and failure of an organization is also linked with its leaders...
We present an interdisciplinary approach that, by incorporating a range of experimental and computational techniques, allows the identification and characterization of functional/immunogenic domains. This approach has been applied to ArtJ, an arginine-binding protein whose orthologs in Chlamydiae trachomatis (CT ArtJ) and pneumoniae (CPn ArtJ) are shown to have different immunogenic properties ...
