Natural and Human Effects on Ecosystem Processes
Convenors
Janet Wilmshurst, Amalava Bhattacharyya, Mukund Kajale
Description
Increasingly, detailed palaeoecological reconstructions are being used to help understand current ecological processes and to address global conservation issues. Palaeoecological studies are starting to move beyond merely presenting trajectories of species composition over time, towards more detailed analyses of species dynamics and responses to both natural and human induced forces.
We invite presentations on palaeoecological studies that evaluate ecosystem responses to lost or altered ecological interactions; species extinctions and introductions; extinction lags; disrupted mutualisms; nutrient cycling and changing herbivory regimes. We encourage studies based on any type of archive (e.g., sediments, coprolites, nests, cave deposits, tree rings etc).
