The common bottlenose dolphin (Tursiops truncatus) is a cosmopolitan delphinid, regularly present in the Mediterranean Sea. According to previous studies, this tends form resident geographical units scattered on continental shelf. We investigated how physiographic characteristics of area residence, with special reference size and shape shelf, affect home range group local units. analysed compar...

Key to understanding the implications of climate and land use change on biodiversity and natural resources is to incorporate the physiographic platform on which changes in ecological systems unfold. Here, we advance a detailed classification and high-resolution map of physiography, built by combining landforms and lithology (soil parent material) at multiple spatial scales. We used only relativ...

Riverine ecosystems are linked to their watersheds, and both land use and physiographic environmental conditions influence nutrient dynamics and water quality. We assessed aquatic nutrients and their relationship with land use and physiographic conditions at multiple spatial scales in the Brazos River watershed (Texas, USA) to examine the interactions between land use and physiography and their...

Soil degradation is one of the most important obstacles to agricultural development. In past few years, there has been interest from research agencies and relevant ministries control soil in Egyptian lands. This study aims assess , productivity correlation coefficient between them Bilqas District, Dakahlia Governorate. To achieve this goal, data for area were taken a previous (2010) compared wi...

Management of desert grasslands requires rapid, low technology, coarse assessment methods that provide a triage-like prioritization for the manager. Such approaches necessitate the ability to quickly and effectively identify coarse-scale plant communities that provide guidance for this prioritization. Complex, computer intensive digital image classification of Landsat TM data, while marginally ...
