Potential in Palaeoecological Reconstruction from Modern Pollen Calibrations along the Kukrail Reserve Forest, Central Ganga Plain, India

open access: yesJournal of the Palaeontological Society of India
Deciphering past vegetation composition can be upgraded by examining modern pollen rain and extant vegetation. Here, we compare pollen dataset of 15 surface soil samples from the forested area and open-land and crop-land areas of the Kukrail Reserve ...

Pollen Analysis of a Peat Deposit in Livingston County, Illinois [PDF]

open access: yes, 1951
This study essays to compare, and in some degree to supplement, pollen analyses thus far published for Illinois. Even though results of studies of fossil pollens seem very similar, each pollen profile is individual and varies in many details from all ...

The Evolution of Agrarian Landscapes in the Tropical Andes

open access: yesPlants
Changes in land-use practices have been a central element of human adaptation to Holocene climate change. Many practices that result in the short-term stabilization of socio-natural systems, however, have longer-term, unanticipated consequences that ...
