Groundwater Vulnerability in Different Climatic Zones

Models for estimating phytoplankton population densities under different environmental conditions with emphasis on climatic factors

The aim of this study is to determine the effect of environmental conditions with emphasis on the main meteorological factors (air temperature variables, sunshine hour, and humidity), on phytoplankton communities. As important primary producers in aquatic ecosystems, phytoplankton communities could be affected by several factors. Environmental factors play the major role in occurrence and diver...

Environmental survival of Mycobacterium avium subsp. paratuberculosis in different climatic zones of eastern Australia.
