A new species in one of the largest genera of Macrosiphini (Hemiptera, Aphididae), Acyrthosiphon pilosum sp. n., is described from apterous and alate viviparous females and oviparous females from French and Spanish Mediterranean localities, living on species of Ononis (Fabaceae), mainly O. natrix. The new species is characterized by the presence of many accessory setae on the ultimate rostral s...
Despite a recent shift towards sustainable practices to support the conservation of traditional olive groves, little is known about their potential threats herpetofauna species. On island Lesvos, one main olive-growing islands in Mediterranean, cultivation often prioritizes expeditious harvesting olives with minimal or no supplementary intervention, resulting generally suboptimal management, co...
Studies of fungi and fungus- like organisms in the northeastern Poland have mainly concentrated on running waters in the vicinity of Białystok, including the Horodnianka River. The main objective was to investigate biodiversity of fungi and fungus-like organisms which take part in decomposition of organic matter commonly found in inland waters. To obtain a complete picture of species compositio...
منطقه شکار ممنوع سفیدکوه و آرسک دامغان با مساحت 666000 هکتار در شمال غربی شهر دامغان در مسیر جاده تهران ـ مشهد حدفاصل کیلومتر 20 تا 22 جاده دامغان به سمنان و در ضلع شمال این جاده واقع میباشد. این مطالعه به منظور شناسایی فون خزندگان این منطقه از فروردین ماه 1392 تا اواخر آبان ماه 1392 انجام شد. در طی مدت تحقیق 93 نمونه خزنده جمع آوری گردید و در مجموع هفده گونه از شش خانواده و سیزده جنس...
For animal populations in many parts of the world, direct (albeit often accidental) killing by humans may be a signi®cant source of mortality. Many snakes are killed by people (especially by automobiles) every year, but the determinants of a snake's vulnerability to anthropogenic mortality (and thus, patterns of mortality with respect to sex, age and season) are poorly known. We present data on...
Snake lungs show a remarkable diversity of organ asymmetries. The right lung is always fully developed, while the left lung is either absent, vestigial, or well-developed (but smaller than the right). A 'tracheal lung' is present in some taxa. These asymmetries are reflected in the pulmonary arteries. Lung asymmetry is known to appear at early stages of development in Thamnophis radix and Natri...
