Forest fires pose a threat more serious than illegal felling in developing countries and are a cause of major concern for environmental security. Fires in tropical forests, though not devastating on a large scale as compared to large and infrequent fires in boreal or Mediterranean systems, still cause loss to biodiversity and economic and monetary value. In India, human-induced forest fires inc...

iran has mountainous landscapes and half of its surface is occupied by highlands. moreover, iran is an arid country and deserts are located at lower altitudes. most metropolitan areas are positioned in mid-altitudes between mountain and desert. cities grow upwardly toward the highlands under pressures of urbanization and desertification. foothill ecotones are a zone between upland mountains and...

Owing to its unique position within multiple monsoon regimes, latitudinal extent, and complex topography, Vietnam is divided into seven agroclimatic zones, each with distinct rainy season characteristics. Variation in the dominant rainfall system across zones affects climatology, primary water resource for regional crops. This study explores creation of an agronomic onset based on high-resoluti...

Historical Diversification of Montane Herpetofauna Within and Between the Sierras of Mexico by Robert W. Bryson, Jr. Dr. Brett R. Riddle, Examination Committee Chair Professor of Biological Sciences University of Nevada, Las Vegas The Mexican highlands consist of four major mountain ranges spanning most of mainland Mexico. The evolutionary history of the Mexican highlands has been shaped by var...

Early extrusive volcanism from mantle melting marks the transition from primary to secondary crust formation. Detection of secondary crust is often obscured by the high impact flux early in solar system history. To recognize the relationship between heavily cratered terrain and volcanic resurfacing, this study documents how volcanic resurfacing alters the impact cratering record and models the ...

OBJECTIVES Herbal medicine is known as a valid alternative treatment. Salvia Reuterana, which has been used in the Iranian traditional medicine, is mostly distributed in the central highlands of Iran. Salvia Reuterana is a medicinal herb with various therapeutic usages. The aim of the present review is to take account of pharmacological properties of Salvia Reuterana. MATERIALS AND METHODS Th...

Florida ranks first in citrus production, with nearly 68% of all U.S. citrus growing in the season 2005–2006. Most of the citrus groves are located from central to south Florida, and agricultural irrigation permitting is regulated by three of Florida’s five water management districts. Most of the permitting for citrus production in Highlands, Polk and Hillsborough counties is conducted by the S...

We test the hypothesis that tree species previously known as Deinbollia sp. 2 . is a new for science. formally characterise and name this onanae (Sapindaceae-Litchi clade) we discuss it in context of assemblage montane Cameroon Highlands West-Central Africa. The shade-bearing, non-pioneer understorey forest reaching 15 m high trunk diameter can attain over 40 cm at 1.3 above ground. Seed disper...

The neotropical Guayana Highlands (GH) are one of the few remaining pristine environments on Earth, and they host amazing biodiversity with a high degree endemism, especially among vascular plants. Despite the lack of direct human disturbance, GH plants and their communities are threatened with extinction from habitat loss due to global warming (GW). Geographic information systems simulations i...

Cameron Highlands is a mountainous area subjected to torrential tropical showers. It extracts 5.8 million liters of water per day for drinking supply from its rivers at several intake points. The water quality of rivers in Cameron Highlands, however, has deteriorated significantly due to land clearing for agriculture, excessive usage of pesticides and fertilizers as well as construction activit...
