As demonstrated in the previous chapter, snow interacts strongly with the global climate system, both influencing and forming as a result of this system. The following chapters discuss the interaction of snow with the chemical and biological systems. This chapter discusses the physical properties of snow as the habitat and regulator of the snow ecosystem. In this sense, the physical snow cover ...

The world is witnessing the birth of a revolutionary computing paradigm that promises to have a profound effect on the way we interact with computers, devices, physical spaces, and other people. This new technology, called ubiquitous computing, envisions a world where embedded processors, computers, sensors, and digital communications are inexpensive commodities that are available everywhere. U...

In the framework of a European Union project a method is needed that allows rapid, standardized, and comparable assessment of the recent state of biodiversity in several countries at the same time. Landscape ecological research in the last decades showed that diversity of species can be correlated to the diversity of their habitats, and that remote sensing images provide good basis for this ass...

1. Many animals forage for non-food objects, such as nesting materials. In many organisms, the depots of such objects can be expansive, and are not intuitively adaptive. This study empirically explores varying theories for why these depots exist in the Florida harvester ant, Pogonomyrmex badius . 2. The Florida harvester ant, like its western congeners, collects and deposits large quantities of...
