Modelling the oxygen isotope distribution of ancient seawater using a coupled ocean–atmosphere GCM: Implications for reconstructing early Eocene climate (2010, background): “Published CO2 values include: ∼700–4600 ppm from Boron isotopes (Pearson and Palmer, 1999, 2000; Pagani et al., 2005); 350– 2700 ppm from δC of pedogenicminerals and 400 ppm from stomatal densities and indices in plants (Royer et al.”
The age of the grasses and clusters of origins of C4 photosynthesis (2008, methodology): “Graph of pCO2 is from Pagani et al. (2005) and @ 18O from Zachos et al. (2001).”
Evolution and the latitudinal diversity gradient: speciation, extinction and biogeography. (2007, background): “Figure 2 Cenozoic changes in palynomorph diversity in a lowland tropical setting (Jaramillo et al. 2006), d 18 O as a proxy for temperature (Zachos et al. 2001; Pagani et al. 2005), CO 2 concentrations (Zachos et al. 2001; Pagani et al. 2005), and megathermal rain forest extent (Morley 2000).”
Sea ice feedback and Cenozoic evolution of Antarctic climate and ice sheets (2007, background): “carbon cycle recognized in proxy reconstructions of CO2, carbon isotopes, and changes in the calcium compensation depth of the oceans [Coxall et al., 2005; Lear et al., 2004; Pagani et al., 2005].”
Carbon isotope compositions of terrestrial C3 plants as indicators of (paleo)ecology and (paleo)climate (2010, neutral): “Eocene pCO2 estimates of 1,000–1,500 ppm (40), δ(13)Catm of −5.”
The origins and diversification of C4 grasses and savanna‐adapted ungulates (2009, background): “…there has been increased interest in understanding the evolutionary histories of C4 plants because of their impact on ecosystem functioning, climates (Cerling et al., 1997; Pagani et al., 2005) and the evolution of animals such as hominids and mammals (Janis, 1993; Macfadden & Cerling, 1994).”
Biochemical and physiological bases for the use of carbon and nitrogen isotopes in environmental and ecological studies (2015, methodology): “The equation given above has been applied when reconstructing the CO2 concentrations in water or the atmosphere in the geological past (e.g., Pagani et al. 2005).”
Plant CO2 responses: an issue of definition, time and resource supply. (2006, background): “For most of the (warm) Mesozoic, CO2 concentrations were much higher than today and then dropped dramatically a third time in the Tertiary (Pagani et al., 2005), when most modern plant genera evolved.”
