Sweta bambusanasp. n. (Hemiptera: Cicadellidae: Typhlocybinae: Dikraneurini), a new bamboo-feeding species, is described and illustrated from Guizhou and Guangdong of China. This represents the first record of the genus Sweta Viraktamath& Dietrich from China and the second known species of the genus. The new taxon extends the range of the genus Sweta, previously known only from northeast India ...

Key biotic and environmental constraints on the host-orientated behaviour of haematophagous Diptera are summarized. For each major group of biting Diptera, responses to host stimuli are reviewed, including activation and ranging behaviour, long-range and short-range olfactory responses and visual responses. Limitations to the comparison of results between groups of species, and the practical pr...

The taxonomy, morphology and distribution of  rust species on Arundineae (Poaceae) in Iran was studied. Five species of Puccinia viz. P. magnusiana Körn., P. phragmitis (Schumach.)Körn., P. isiacae G. Winter, P. trabutii Roum. & Sacc. and P. akiyoshidanensis Morim. are described and illustrated. Of these, Puccinia akiyoshidanensis is considered as a distinct species and newly recorded for Irani...

Present work deals with providing an identification key to 60 Iranian species of the family Isotomidae. The photographic support provided here, both light micrographs and scanning electron microscopy (SEM) pictures, can be used as a practical tool for researchers who are not well acquainted morphology

This paper presents a novel method for tone mapping high dynamic range images and videos for display in conventional low dynamic range devices. The new multi-curve method uses tone mapping curves that are adaptive to local luminance levels. The new method has the computational simplicity of curve based tone mapping methods and achieves results comparable to spatial operator methods. When applyi...

PREMISE OF THE STUDY Automatic self-fertilization may influence the geography of speciation, promote reproductive isolation between incipient species, and lead to ecological differentiation. As such, selfing taxa are predicted to co-occur more often with their closest relatives than are outcrossing taxa. Despite suggestions that this pattern may be general, the extent to which mating system inf...

This study was conducted to identify and classify the lichens; determine the diversity index and richness of lichens. A total of 36 species belonging to six genera under three families was identified. Lichen species were mostly found at moderate high altitudinal range with an elevation of 1,131 meters above sea level and open areas where they received adequate sunlight with high moisture and hu...

Information on different rangeland plants’ nutritive values during variousphonological stages is of importance for the rangelands management. This information helpsrangeland managers to choose proper grazing times to achieve higher animal performancewith no detrimental effects on the rangeland vegetations. Effects of various plant parts’phenological stages and vegetation types on reserve carboh...

Fire is one of the incorporate vegetation management practices for grasslands and semi-arid rangelands. It may affect symbiotic relationship between range plants and mycorrhiza. Accordingly, this research was aimed to investigate the effects of a spring prescribed fire on the symbiotic relationships between mycorrhiza and 6 plant species. The study was conducted in a semi-arid steppe rangeland ...
