Litter decomposition during winter can provide essential nutrients for plant growth in the subsequent growing season, which plays important role in preventing the expansion of dry areas and maintaining the stability of ecotone ecosystems. However, limited information is currently available on the contributions of soil fauna to litter decomposition during winter in such ecosystems. Therefore, a ...

Family Cupressaceae is the largest coniferous plant family. Essential oils of many species belonging to family Cupressaceae are known to have several biological activities specially antimicrobial activity. The essential oils from aerial parts of Calocedrus decurrens Torr., Cupressus sempervirens stricta L. and Tetraclinis articulata (Vahl) Mast. were prepared by hydrodistillation. The chemical ...

Bio-monitoring of air quality in Amman City was investigated by analyzing 36 cypress tree (Cupressus semervirens L.) bark samples from three sites of different anthropogenic activities at the end of summer season 2001. Cypress barks were found to be a good bio-indicator for air pollution in arid regions. Variation in Pb, Zn, Mn, Cr, Ni, Cd, and Cu contents between sites was observed due to diff...

Over the past 70 years a destructive blight of Cupressus macrocarpa and other Cupressaceae, caused by Seiridium cardinale, has spread worldwide from California, devastating forests, plantations, and ornamental cypresses. The epidemic has been particularly severe in the Mediterranean region, on C. sempervirens. A similar destructive blight induced by Lepteutypa cupressi, which caused serious los...

This study aimed to evaluate in-vitro antioxidant activities of hydroethanolic extract of leaves of Cynara scolymus L., Cupressus sempervirens L., and Eugenia jambolana Lam comparing with ascorbic acid, and their correlation with in-vivo hepatoprotective activity in rat model of paracetamol-induced hepatotoxicity, comparing with silymarin as reference agents. In-vitro study revealed that the te...

During past few years, the Cupressus arizonica has been abundantly planted in Tehran, causing a significant increase of allergic diseases from the middle of winter to the beginning of spring. The aim of this study was the comparison of pollen protein content in two major varieties of C. arizonica planted in Tehran, including C. arizonica var. arizonica and C. arizonica var. glabra, in order to ...

Cupressus sempervirence var. horzontalis belong to the Cupressus family. This species is evergreen and grows within an elevation range of 290 meters and 1200 meters above sea level in the North of Iran. The extraction of texture features from high-resolution remote sensing imagery provides a complementary source of data for those applications in which the spectral information is not sufficient ...

Forest degradation influences ecosystem sustainability and reduces plant species diversity. Plantations with coniferous trees in degraded ecosystems help the native species to become established and play a major role in preserving and improving plant diversity. This study aims at measuring and comparing the woody species diversity across different age classes of Pinus brutia and Cupressus horiz...
