Humus forms are good indicators of environmental conditions and thus important in forest ecological processes. Altitudinal gradients considered as natural laboratory for evaluating soil processes humus form distribution. The objective this study was to evaluate the macromorphology along an altitudinal gradient (0-2000 m a.s.l.) covered with plain forest, mixed pure forests forest-grassland ecot...

Soybean-nodulating bradyrhizobia are genetically diverse and are classified into different species. In this study, the genetic diversity of native soybean bradyrhizobia isolated from different topographical regions along the southern slopes of the Himalayan Mountains in Nepal was explored. Soil samples were collected from three different topographical regions with contrasting climates. A local ...

In northern parts of Iran such as the Alborz Mountain belt, frequent landslides occur due to a combination of climate and geologic conditions with high tectonic activities. This results in millions of dollars of financial damages annually excluding casualties and unrecoverable resources. This paper evaluates the landslide susceptible areas in Central Alborz using the probabilistic frequency rat...

This paper expands the previous efforts by other researchers to present a quantitative and deterministic approach for terrain analysis. This study evaluates both spatial and temporal factors contributing landslides utilizing Light Detection and Ranging (LiDAR) point clouds in conjunction with the frequency ratio model (PFR) than has previously been used in the Alborz Mountains. The study area i...

Following the description of the Apatophyseini genus Apterotoxitiades Adlbauer, 2008 (Cerambycidae: Dorcasominae) from South Africa, a new species has now been discovered in the eastern Drakensberg range of the country. The holotype female is here described as Apterotoxitiadesaspinosus Björnstad, sp. n. Also, a new small series collected at Hogsback, in the Amathole range, has allowed the descr...

This study was carried out to determine species composition of sooty mold fungi on Citrus species in Gilan Province, which is located in the North of Iran. This region isolated by Alborz mountain range from other parts of the country with maximum rainfall about 2000 mm/year. A total of seven species belonging to various genera of mitosporic fungi viz., Conidiocarpous penzigii, C. cf. caucasicus...

The Alborz mountain range in northern Iran is part of the active and seismic Alpide belt, where assessing hazards crucial due to region’s history large instrumental earthquakes destructive background. Moment rate estimation, which quantifies tectonic activity, offers a novel approach understanding energy potential regions. In this study, regional perspective employed investigate maximum horizon...

While rock glaciers (RGs) are widespread in the Zhetysu Alatau mountain range of Tien Shan (Kazakhstan), they have not yet been systematically investigated. In this study, we present first glacier inventory region containing 256 with quantitative information about their locations, geomorphic parameters, and downslope velocities, as established using a method that combines SAR interferometry opt...
