TL;DR: The Siwalik formations of northern Pakistan consist of deposits of ancient rivers that existed throughout the early Miocene through the late Pliocene as mentioned in this paper, and they provide an opportunity to document temporal differences in species richness, turnover and ecological structure in a terrestrial setting, and investigate how such differences are related to changes in the fluvial system, vegetation, and climate.

TL;DR: Radioisotopic and paleomagnetic analyses indicate that the flora was deposited 52 million years ago, the time of the early Eocene climatic optimum, when tropical plant taxa and warm, equable climates reached middle latitudes of both hemispheres.

TL;DR: The results suggest that populations of both rare and common mammals are currently losing genetic diversity and that conservation efforts focused above the population level may fail to protect the breadth of persisting genetic diversity.

TL;DR: In this paper, the authors describe the preliminary results of their investigation of Oldowan occurrences at Kanjera South, which preserve the oldest known traces of hominid activity in southwestern Kenya, and unlike most of the Oldowan sites in a relatively open (>75% C4 grass) habitat.

TL;DR: The authors used stable isotope variation within individual Mio-Pliocene paleosols to investigate subkilometer-scale phytogeography of late Miocene vegetation change in southeast Asia between ca. 8.1 and 5 Ma, a time interval that coincides with dramatic global vegetation change.
