introduction identification of active tectonic areas, especially in convergent zone are very important because of their potential risks. nowadays, there are several algorithms that are used for tectonic analysis; one of them is tecdem that is used in this research. in this study, using remote sensing techniques, geomorphometric analysis and fieldwork were conducted to analyze morphometric and g...
In this study where done in Babolroud basin, seven models include MPSIAC, EPM, Fournier, Douglas, Kirkby, Geomorphology and Hydrophysical was evaluated to determine the best model for estimation of soil erosion and sediment yield. These models have not been compared together as integrated in the previous researches. The zoning soil erosion intensity map was prepared for each model using GIS. T...
Partaking in this grisly feast are the larvae of a parasitoid wasp, Copidosoma floridanum. Like other wasps, Copidosoma are haplodiploid: Fertilized eggs produce females; unfertilized eggs become males. These wasps are also polyembryonic: Eggs split to produce many clonal embryos. A single host may contain multiple eggs from multiple females, resulting in a hodgepodge of genetic relationships. ...
