Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 83-102., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Cytoplasmic Lipid Membrane Biogenesis in Prokaryotes: From Soluble Lipid Building Blocks to a Dynamic and Functional Boundary Layer [PDF]

open access: yesChembiochem
Lipid membranes are fundamental to all prokaryotic life. Besides acting as barrier, by orienting as hydrophobic bilayer, lipids are involved in a wide variety of other cellular processes. As a consequence, prokaryotic membranes are dynamic entities that switch their lipid composition as required; a process that requires tight interplay with the lipid ...

Temperate Oligocene surface ocean conditions offshore of Cape Adare, Ross Sea, Antarctica [PDF]

open access: yesClimate of the Past, 2021
Antarctic continental ice masses fluctuated considerably during the Oligocene “coolhouse”, at elevated atmospheric CO2 concentrations of ∼600–800 ppm. To assess the role of the ocean in the Oligocene ice sheet variability, reconstruction of past ocean ...

The Effects of Temperature and Growth Phase on the Lipidomes of Sulfolobus islandicus and Sulfolobus tokodaii

open access: yesLife, 2015
The functionality of the plasma membrane is essential for all organisms. Adaption to high growth temperatures imposes challenges and Bacteria, Eukarya, and Archaea have developed several mechanisms to cope with these.

Membrane homeoviscous adaptation in the piezo-hyperthermophilic archaeon Thermococcus barophilus

open access: yesFrontiers in Microbiology, 2015
The archaeon Thermococcus barophilus, one of the most extreme members of hyperthermophilic piezophiles known thus far, is able to grow at temperatures up to 103°C and pressures up to 80MPa. We analyzed the membrane lipids of T. barophilus by HPLC-MS as a

Archaeal intact polar lipids in polar waters: a comparison between the Amundsen and Scotia seas [PDF]

open access: yesBiogeosciences, 2021
The West Antarctic Ice Sheet (WAIS) is one of the largest potential sources of future sea-level rise, with glaciers draining the WAIS thinning at an accelerating rate over the past 40 years.

Influence of Growth Phase, pH, and Temperature on the Abundance and Composition of Tetraether Lipids in the Thermoacidophile Picrophilus torridus

open access: yesFrontiers in Microbiology, 2016
The abundance and composition of glycerol dibiphytanyl glycerol tetraether (GDGT) and glycerol tribiphytanyl glycerol tetraether (GTGT) lipids were determined as a function of growth phase as a proxy for nutrient availability, the pH of growth medium ...
