piptatherum denaense به عنوان گونه ای جدید از کوه دنا در جنوب غرب ایران شرح داده می شود. این گونه با داشتن پوشینه بدون کرک در بخش تحتانی و انتهایی، بساک بدون کرک و برگ های رویشی باریک از گونه نزدیک به آن، p. laterale، تفاوت دارد. p. holciforme subsp. holciforme var. glabrum به عنوان یک واریته مشخص مورد تایید قرار نمی گیرد. p. sphacelatum که قبلا با گونه p. molinioides مترداف شده بود با ...

Successful conservation of long-lived species requires reliable understanding long-term trends and historical baselines. We present a framework for evaluating abundance outcomes marine by integrating local ecological knowledge (LEK), monitoring, computer simulation, tested on case-study heavily exploited green turtles (Chelonia mydas) in the Eastern Pacific. Models fit to LEK monitoring data in...
Goniopsarites gen. nov. is described from China in the tribe Pisachini with G. fronticonvexus sp. nov. as the type species. The genus Pisacha is revised, four new species P. yinggensis sp. nov., P. baculiformis sp. nov., P. falcata sp. nov., P. balteiformis sp. nov. are described, and P. encaustica (Jacobi, 1916) comb. nov. & stat. rev. is reestablished which has been treated as P. naga accordi...
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...
Microtopography is a characteristic feature of many natural wetlands that is commonly lacking in restored wetlands (RWs). Consequently, it has been suggested that microtopography must be reestablished in RWs to accelerate the development of wetland function. The objective of this research was to examine responses of hydrology, soils, and vegetation to microtopographic reestablishment at a 3-yea...
the community dynamics of aquatic coleoptera(insecta)in one of the spring-stream habitats of bammo national park in fars province called cheshmeh-ye-ghanbari is studied as a pilot project and model for acquaintance with and furthering the biodiversity studies on fauna of iran. sixteen species-populations out of nineteen of this community were already identified for their taxonomy and for thei...
The recognition that taxonomy is central to the conservation of biodiversity has reestablished the critical role of taxonomy in biology. However, many of the tools taxonomists produce for the identification and characterization of species, e.g., dichotomous keys, have been difficult to use and largely ignored by the general public in favor of field guides, which are essentially browsable pictur...
