Beavers and the dams they build promote sediment deposition and modify channel and floodplain morphology and physical complexity. Beaver activities may result in increased watershed-scale water and ...

The extent to which non-host-associated bacterial communities exhibit small-scale biogeographic patterns in their distribution remains unclear. Our investigation of biogeography in bacterial community ...

Phase transition: Aerial photograph of Arctic melt ponds (Courtesy: Healy–Oden Trans-Arctic Expedition (2005)) A new computer model can simulate how ponds of meltwater form and evolve on the surface ...

Though billions of people are without adequate fresh-water resources, even more people lack effective sanitation services. This latter concern is the focus of an appropriate technology initiative ...

The dynamics of turbulent fluid flow coupled to the precipitation-driven growth of the travertine substrate was modelled on a discrete lattice of cells. Our cell dynamical system (CDS) is a set of ...

A total of 119 waterbodies situated in the villages of eight districts of Delhi are being developed as ‘model ponds’. These ponds will have to meet certain parameters like no foul smell, presence of ...
