In many studies, topographic factors have been considered as an important factor in establishing the vegetation in different ecosystems. So, it affects vegetation composition and diversity by influencing soil moisture, fertility and soil depth. The aim of this research was to investigate the effects of slope, elevation and geographical aspects on species growth, forage production and vegetation...

The SPINUA (Stable Point INterferometry over Unurbanised Areas) processing chain has been developed and tested in the framework of ASI-, ESAand EUfunded projects, and represents an effort to adapt and optimise the general approach of long-term SAR interferometry for the study of un-urbanised areas such as those typical of Mediterranean sites affected by slope instabilities. In this work, the SP...

Obtaining high resolution Digital Elevation Models (DEMs) is a critical task for analysis and visualization in several remote sensing applications. LIDAR technology provides an effective way for obtaining highresolution topographic information. This paper presents a textured-based novel automatic algorithm for DEM generation from LIDAR data. The proposed technique uses multifractal-based textur...

Plant diversityis essential to maintain the health of planet's ecosystems. Conservation of biodiversity is necessary for the ecological stability and productivity in natural ecosystems. The aim of this research was to study the biodiversity and richness of plant species (including trees, shrubs and grasses) related to the environmental factors (soil and physiography) in the forests of Zagros, w...

Small animals are remarkably efficient climbers but comparatively poor runners, a well-established phenomenon in locomotor energetics that drives size-related differences in locomotor ecology yet remains poorly understood. Here, I derive the energy cost of legged locomotion from two complementary components of muscle metabolism, Activation-Relaxation and Cross-bridge cycling. A mathematical mod...

forest road construction is the most costly operation in forestry. road designing and construction in unsuitable areas may increase construction and maintenance costs and also cause many environmental impacts. therefore, it is required to pay more attention to forest road design. in this research, we tried to introduce an appropriate method for locating forest roads using gis and ahp simultaneo...
