In Russia and the adjacent territories, the genus Hephathus includes three species, H. nanus (Herrich-Schäffer, 1835), H. freyi (Fieber, 1868) = H. tshakaranus Dlabola, 1957, syn. n., and H. achilleae Mityaev, 1967. They are indistinguishable in genitalia shape, but differ in male calling signal structure and black pattern of face. Photos of habitus and face, drawings of genitalia and male 2(nd...

Basic knowledge about the distribution of flora and fauna is lacking for most tropical areas. Improving our knowledge of the tropical biota will help address contemporary global problems, including emerging tropical diseases. Less appreciated is the role that applied studies can have in improving our understanding of basic biological patterns and processes in the tropics. Here, I describe a nov...

A few dominant tree species in temperate forests of western Himalayas have been mapped using Hyperion data. The data was processed for removing atmospheric distortions using FLAASH before classification. The replicate spectral profiles were collected in ground using field spectrometer (ASD) during same season for classification. Reconnaissance survey was conducted to locate populations or suffi...

A new telomycin-like cyclic depsipeptide, ambobactin (1), was isolated from the metabolites of Streptomyces ambofaciens F3, an endophyte of Platycladus orientalis. Its structure was elucidated on the basis of extensive spectroscopic analysis and advanced Marfey's method. Ambobactin is structurally related with telomycin, except that the configuration of the 3-methyltryptophanes in their structu...

The genus Aplomerus Provancher, 1886 (Hymenoptera, Ichneumonidae) is a small genus of the subfamily Xoridinae. Two new species from Asia, A. orientalis Varga & Reshchikov sp. n. from Thailand and A. phamae Broad sp. n. from Vietnam, are described and illustrated. An identification key for Asian species is provided. These are the first records of the genus from the Oriental region and increases ...

The structure and leaf development of the shoot apical meristem in embryos and seedlings of Thuja orientalis L.were observed by using SEM,and the area of the shoot apical meristem was studied by an image analyzer.The shoot apex of embryos was of a round tip cone shape with flat sides;it was transformed into an inverted boat shape.In seedlings,the shoot apical meristem was of a convex-rectangula...
