Archaeological and theoretical evidence reviewed here indicates that Clovis-era foragers exterminated mammoths and mastodonts in North America around 11,000 radiocarbon years ago. The process unfolded quickly as human foragers explored and dispersed into fragmenting habitats where megamammal populations were ecologically stressed. Megamammal extinctions were eco-catastrophes with major ripple e...

Mosquito faunal surveys were carried out in different habitats of 11 hill ranges of the Western Ghats between 2000 and 2012. Thirty three anopheline species were examined and recorded out of 8730 specimens belonging to subgenera Anopheles (12) and Cellia (21). Very low densities of malaria vectors Anopheles (Cellia) fluviatilis (0.7%) and An. (Cel.) culicifacies (3.04%) were also recorded.

Oxygen and carbon isotope ratios of benthic foraminifers were measured on the continuous middle to lower bathyal sedimentary sequence dated from the upper Maestrichtian to lower Eocene which was recovered at Site 752 in the eastern Indian Ocean. The changes in the carbon isotope values can be correlated with the faunal changes of the benthic foraminifers.
