A key issue in climate change is the extent to which there are changes variables that may be consistent with anthropogenically induced change. In this paper an attempt has been made apply two-phase regression model records of long term annual mean surface air temperature over India examine whether any significant trends across country. We find most stations selected for study, show acceleration...

Abstract The aim of our work was to experimentally test the hypothesis that changes in thermal stratification lakes temperate zone, expected as a result progressive global warming, will cause an increase fitness costs planktonic cladoceran Daphnia , associated with diel vertical migrations. In programmable thermostatic chamber, magna have been cultured from first juvenile instar till reproducti...
