This paper describes a series of experiments that were performed on the Rocky III rob0t.l Rocky III is a small autonomous rover capable of navigating through rough outdoor terrain to a predesignated area, searching that area for soft soil, acquiring a soil sample, and depositing the sample in a container at its home base. The robot is programmed according to a reactive behaviorcontrol paradigm ...

rocky shores are one of the most important habitats of marine environment in coastal areas. they host marine organisms including seaweeds because of existence of strong and stable substrate for their growths. intertidal rocky shores are a prominent feature on coastal areas of qeshm island located at the northern part of strait of hormuz. in order to study biomass of seaweeds on rocky intertidal...

PREMISE OF THE STUDY Population genetic analyses provide information on the population context in which evolutionary processes operate and are important for understanding the evolution of geographically variable traits. Earlier studies showed that cone structure of lodgepole pine in the Rocky Mountains diverged among populations because of geographic variation in coevolutionary interactions inv...

Karst rocky desertification is a special kind of land desertification developed under violent human impacts on the vulnerable ecogeo-environment in karst ecosystem. The process of karst rocky desertification results in simultaneous and complex variations of many interrelated soil, rock and vegetation biophysical parameters, rendering it difficult to develop simple and robust remote sensing mapp...
