Current and Cretaceous-Cenozoic diversification of Angiosperms

Cretaceous-Cenozoic history of angiosperms led to the a certain character of the distribution of taxa of different levels (the number of species and genera in families, species/genera ratio in families, the number of species in the genera). In most cases, these distributions are satisfactorily described by a power law (Pareto distribution). In logarithmic coordinates power function is a straigh...

Prehistoric Mobility in Polynesia: MtDNA Variation in Rattus exulans from the Chatham and Kermadec Islands

Irwin (1992) has suggested that island accessibility in the Pacific, in terms oflatitudeand safety of return voyaging, for example, affects their degree of contact with otherislands and their role in Pacific prehistory. We present results of mtDNA variationin both ancient and modern populations of the Pacific Rat (Rattus exulans), an ani-mal that was transported by humans as the...

Geobiological constraints on Earth system sensitivity to CO₂ during the Cretaceous and Cenozoic.

Earth system climate sensitivity (ESS) is the long-term (>10³ year) response of global surface temperature to doubled CO₂ that integrates fast and slow climate feedbacks. ESS has energy policy implications because global temperatures are not expected to decline appreciably for at least 10³ year, even if anthropogenic greenhouse gas emissions drop to zero. We report provisional ESS estimates of ...
