Paleoecology is the scientific discipline dedicated to the study of ancient ecosystems, investigating the interactions between organisms and their environments across geological time scales. It reconstructs past ecological conditions and dynamics using evidence from the fossil and geological record, offering insights into the history of life and environmental change.

Chronological and Quantitative Foundations era
Donald A. Walker [1] is highlighted for his role in the Chronological and Quantitative Foundations era, with affiliations at the University of Cambridge [2] and The London College [3]. His key contribution is the 1955 paper 'STUDIES IN THE POST‐GLACIAL HISTORY OF BRITISH VEGETATION' [4], which advanced post-glacial vegetation reconstruction and helped establish standards for biostratigraphic dating in paleoecology. This work, rooted in Walker [1]'s affiliations at the University of Cambridge [2] and The London College [3], crystallized the move toward reproducible chronological inference that underpinned paleoecological frameworks in the era. Its legacy lies in providing a temporally anchored, quantitative foundation that enabled later multi-proxy environmental inferences across marine and terrestrial records.
Orbital and Integrated Stratigraphy era
Dennis V. Kent [1] is associated with Columbia University [3] and University of Glasgow [4] during the Orbital and Integrated Stratigraphy era, contributing to magnetostratigraphy and chronostratigraphic standardization. His key contribution was the Revised magnetic polarity time scale for Late Cretaceous and Cenozoic time [7], which advanced magnetostratigraphy and enabled cross-site sediment correlations at Milankovitch-scale time. Joël Guiot [2] is associated with UCLouvain [5] and Aix-Marseille Université [6] during the Orbital and Integrated Stratigraphy era, contributing to continental climate reconstructions from pollen records. This 1989 paper [8] demonstrated the viability of pollen-based continental climate reconstructions for orbital-scale variability, enabling cross-site syntheses and hypothesis testing in the Orbital and Integrated Stratigraphy framework.
Multiproxy Anthropocene Synthesis era
Pierre Taberlet [1] is associated with Université Joseph Fourier [3] and University of Geneva [4] in this era. His key contribution in this era is the 1998 paper 'Comparative phylogeography and postglacial colonization routes in Europe' [7], which advanced comparative phylogeography and postglacial recolonization mapping in Europe, providing foundational insights for how species recolonized after glacial periods and informing multi-proxy paleoecological reconstructions. Paul R. Ehrlich [2] is affiliated with Stanford University [5] and University of California, Berkeley [6] in this era. His key contribution in this era is the 2017 paper 'Biological annihilation via the ongoing sixth mass extinction signaled by vertebrate population losses and declines' [8], which framed biodiversity loss as an ongoing mass-extinction signal and underscored the urgency of integrating biodiversity trends into conservation baselines and translational frameworks.
