Building the Biomarker Tree of Life (2005, background): “…Talyzina 1998; Brocks et al. 2005), elucidate events of global climate change (e.g., Brassell et al. 1986), record major perturbations and reorganization of geochemical cycles (e.g., Logan et al. 1995; Kuypers et al. 1999) and document catastrophic losses in biodiversity (e.g., Grice et al. 2005).”
The Geological Succession of Primary Producers in the Oceans (2007, background): “…for the Permian Triassic transition represent unpublished data from the Perth Basin, Australia, and the boundary stratotype in Meishan, China; in these sections high 2-MeHI correlate with independent molecular, iron speciation, and sulfur isotopic evidence for intense euxinia (Grice et al. 2005).”
Contributions of anoxygenic and oxygenic phototrophy and chemolithotrophy to carbon and oxygen fluxes in aquatic environments. (2009, background): “…was a third time at which biomarker evidence suggests that green sulfur bacteria were important photolithotrophs in a euxinic marine photic zone, i.e. during the Permian–Triassic boundary mass extinction event some 250 million yr ago, and the 1 million yr or more thereafter (Grice et al. 2005).”
Dynamic Energy Budget Theory for Metabolic Organisation (2005, background): “Biomarkers (isorenieratene) from these bacteria suggest that the great mass extinctions of the Permian, Devonian and Triassic are linked to the toxic effects of hydrogen sulphide and the lack of dioxygen [433, 1215].”
Paleophysiology and End-Permian Mass Extinction (2007, background): “Photosynthetic bacteria, especially cyanobacteria, would have multiplied rapidly to pick up the slack, however, as evidenced by high 2-methylhopanoid indices in basal Triassic shales [36,86].”

All Other Uses, Reproduction and Distribution, including without Limitation Comm (2005, neutral): “An important anisotropic interaction that usually dominates the NMR spectra is the dipole– dipole coupling between every pair of nuclei with spin.”
The palaeoclimatology, palaeoecology and palaeoenvironmental analysis of mass extinction events (2006, positive): “More recent, independent, geochemical and biomarker data has since strengthened the initial interpretations (e.g., Wignall and Twitchett, 1996, 2002; Grice et al., 2005), but still this does not prove that extinction was caused by oceanic anoxia.”
