Soil moisture content (SMC) is a significant factor affecting crop growth and development. However, SMC estimation, based on synthetic aperture radar (SAR), influenced by variety of surface parameters, such as vegetation cover roughness. As result, determining the across agricultural areas (e.g., wheat fields) remotely (i.e., without ground measurement) difficult to achieve. In this study, mode...

Cyclical parthenogens, which combine asexual and sexual reproduction, are good models for research into the ecological and population processes affecting the evolutionary maintenance of sex. Sex in cyclically parthenogenetic rotifers is necessary for diapausing egg production, which is essential to survive adverse conditions between planktonic growing seasons. However, within a planktonic seaso...

In boreal forests, fire is an important part of the ecosystem that greatly influences soil respiration, which in turn affects the carbon balance. Wildfire can have a significant effect on soil respiration and it depends on the fire severity and environmental factors (soil temperature and snow water equivalent) after fire disturbance. In this study, we quantified post-fire soil respiration durin...

Droughts affects on agriculture and water consumption management through LU/LC and water resources changes in western mountainous areas of Iran. The aim of this study was to investigate terrestrial and remote sensing drought indices and their effects on LU/LC and ground water level in Razan-Ghahavand watershed. Precipitation trend in two stations and water level trend in six piezometric well we...
