Madagascar houses one of the Earth’s biologically richest, but also most endangered, terrestrial ecoregions. Although it is obvious that humans substantially altered natural ecosystems during past decades, timing arrival early inhabitants on as well their environmental impact still intensively debated. This research aims to study beginning human Malagasy ecosystems, specifically Nosy Be island ...

A coupled pollen-brGDGT paleoclimate reconstruction approach has been tested to provide independent and robust estimates of Holocene climate environment changes in the extremely arid mountainous areas ranging from northern Arid Central Asia (ACA) Mongolian Plateau. The two proxies were calibrated for both global local modern data sets (NMSDB). This multi-proxy was then applied a sediment core c...

The evolution of life on Earth has been interrupted by several mass extinction events. The Cretaceous-Tertiary (K-T) extinction [65 million years ago (Ma)] is associated with the impact of a large bolide (1). On the basis of extensive data (2–4), the K-T boundary is characterized by a palynological extinction horizon coincident with a geochemical marker bed commonly succeeded by a bed rich in f...

The Gippsland Basin Province 3930, located on the southeastern coast of Australia, is formed from two successive failed rifts that developed into a passive margin during the Cretaceous. Formation of this basin is related to the break up of Gondwana, which resulted in the separation of Antarctica from Australia, and the separation of the New Zealand and Lord Howe Rise continental crust from Aust...
