The accumulation of two mercury compounds--HgCl(2) and CH(3)HgCl--by Hexagenia rigida (burrowing mayfly nymphs) from contaminated sediments was investigated experimentally. Three exposure periods were selected: 7, 14 and 28 days. Results reveal a high capacity of this species for Hg accumulation and considerable differences between the two chemical forms of the metal. Thus, the amount of total ...
Phenology is a broad science topic of Ecology. Study of phenology for regulating of animal grazing programs and determining of palatability and nutritive value of plant species at different stages of vital in range is important. This study was carried out to determine the chemical composition and nutritive value of Salsola vermicolata and Suaeda fruticosa that are halophyte plants, in three phe...
objective: salt stress is a world-wide problem and soil salinity is common in arid and semi-arid regions. this study was undertaken to investigate salt tolerance in salsola orientalis in laboratory and natural conditions and recognize the mechanisms that allow it to tolerate these conditions. methods: this study had two parts of greenhouse and natural habitats. the treatment solutions for salin...
آتش سوزی از جمله راهکارهای مدیریتی برای اصلاح مراتع محسوب می شود.در این پژوهش به بررسی اثرات آتش بر گونه های گیاهی مهم در مراتع استپی استان یزد پرداخته شده است. برای این منظور، محدوده ای به وسعت یک هکتار درون ایستگاه تحقیقاتی مرتع نیر یزد انتخاب گردید. این عرصه به 4 بلوک 125×20 متر و هر بلوک به 5 قطعه آمایشی 25×20 متری تفکیک شد. هر قطعه بطور تصادفی به هر یک از تیمارهای 4 گانه زمان آتش سوزی (بها...
We report on screening tests of 66 extracts obtained from 35 marine sponge species from the Caribbean Sea (Curaçao) and from eight species from the Great Barrier Reef (Lizard Island). Extracts were prepared in aqueous and organic solvents and were tested for hemolytic, hemagglutinating, antibacterial and anti-acetylcholinesterase (AChE) activities, as well as their ability to inhibit or activat...
Parapiptadenia rigida, locally known as angico, is a tropical tree common in the semideciduous Brazilian forest. Its wood is naturally resistant to insect attack and is useful for construction. Extracts from the tree have medicinal properties. We characterized nine microsatellite loci for P. rigida. Thirty-five alleles were detected in a sample of 45 individuals from 3 different population...
