tillage systems influence soil physical, chemical and biological characteristics which in turn may alter, root characteristics, growth, and development. a three year study was conducted to investigate the effects of seven tillage systems on some soil (fine-loamy mixed, typic haplocambids) physical characteristics and wheat (triticum aestivum l.) root morphology. tillage treatments included ...

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

The impacts of hot, dry, and compound hot-dry extremes are significant for societies, economies, ecosystems worldwide. Such events therefore need to be assessed in the light anthropogenic climate change so that suitable adaptation measures can implemented by governments stakeholders. Here we show a comprehensive analysis over global land regions using 25 Coupled Model Intercomparison Project Ph...

The research results indicated that wet and dry dust deposition is a function of geographical characteristics. The seasonal wet and dry dust deposition and Fine Particles (PM 2.5) correlation in Iran with elevation, latitude and longitude results that the maximum correlation belongs to height, followed by latitude and longitude; meanwhile height and latitude are strongly and reversely correlate...

Abandonment of agricultural land has resulted in forest regeneration in species-rich dry grasslands across European mountain regions and threatens conservation efforts in this vegetation type. To support national conservation strategies, we used a site-selection algorithm (MARXAN) to find optimum sets of floristic regions (reporting units) that contain grasslands of high conservation priority. ...

To avoid unnecessary waste of limited resources and to help prioritize areas for conservation efforts, this study aimed to provide information on habitat use by elephants between the wet and dry seasons in the Mole National Park (MNP) of Ghana. We compiled coordinates of 516 locations of elephants' encounters, 256 for dry season and 260 for wet season. Using nine predictor variables, we modeled...
