Molecular phylogenies and their application to biogeoGiven the insights of Kondo et al. [1] regarding the graphic questions, as illustrated by Kondo et al. [1] in their study of Livistona palms in Australia, are providing unprecedented insight into speciation and the historical movement of taxa around the world [2]. While such studies often allow for the clarification of taxonomic relationships...

Results The data analyzed so far revealed the presence of different pollen and fungal species at both sites. The ratio between the pollen and fungal spores was 1:5. The airborne pollen grains showed quantitative and qualitative differences between the two sites. At FD site, the major pollen grains included Phoenix dactylifera (31%), grass pollen (14%), Atriplex nummularia (12%), Amaranthus viri...

بیشترین میزان سطح خشکیها در کره زمین به مراتع اختصاص داشته و مرتع اولین منبع ارزشمند تولید علوفه دامها است . جهت بهره برداری صحیح از مراتع نیاز به یک ارزیابی جامع می باشد تا اطلاعات کمی برای آنالیز مرتع تهیه شود. مشخص کردن ظرفیت چرای مراتع براساس میزان علوفه تولیدی در یک دوره رویش یکی از اساسی ترین موارد اداره و مدیریت مرتع است . لازم به ذکر است که قسمت اعظم مراتع کشور ما را بوته زارها فرا گرفت...

Salsola drummondii Ulbr. is a perennial halophyte found in salt deserts of southern Balochistan, Pakistan. Experiments were conducted to study the effects of salinity (0, 200, 400, 600, 800 and 1000 mM NaCl), thermoperiod (10/20, 15/25, 20/30 and 25/35C), light (12-h photoperiod and dark) and dormancy regulating chemicals (DRCs) on germination, recovery and viability of the seeds of S. drummond...

Near complete rabies virus N gene sequences (1,110 nt) were determined for 82 isolates obtained from different regions of Russia between 2008 and 2016. These sequences were analyzed together with 108 representative GenBank sequences from 1977-2016 using the Bayesian coalescent approach. The timing of the major evolutionary events was estimated. Most of the isolates represented the steppe rabies...

The one-loop effective potential in 2D dilaton gravity in conformal gauge on the topologically non-trivial plane IR×S and on the hyperbolic plane H/Γ is calculated. For arbitrary choice of the tree scalar potential it is shown, that the one-loop effective potential explicitly depends on the reference metric (through the dependence on the radius of the torus or the radius of H/Γ). This phenomeno...

The farinose coating on the lower frond surface of the fern Notholaena rigida Dav. was shown pre­ viously to contain the flavones scutellarein-6,7,4'trimethyl ether and scutellarein-6 ,7-dimethyl ether as well as minor amounts of apigenin, apigenin-4'methyl ether, and apigenin-7,4'-dimethyl ether [1], The exudate material also contains a considerable amount of terpenoids, one of which has been ...

Six species of lichens, such as Usnea florida, Usnea barbata, Usnea longissima, Usnea rigida, Usnea hirta and Usnea subflorida, were collected from different areas of Anatolia (district of Antalya, Karabük, Qankiri, Giresun and Trabzon) in Turkey. Their usnic acid amounts in acetone extracts were determined by HPLC. In addition, antimicrobial activities of these extracts were determined against...
