Energy flow through marine ecosystems: confronting transfer efficiency
Transfer efficiency is the proportion of energy passed between nodes in food webs. It is an
emergent, unitless property that is difficult to measure, and responds dynamically to …

An astronomically dated record of Earth's climate and its predictability over the last 66 million years
Much of our understanding of Earth's past climate comes from the measurement of oxygen
and carbon isotope variations in deep-sea benthic foraminifera. Yet, long intervals in …

[HTML][HTML] Enhanced ocean oxygenation during Cenozoic warm periods
Dissolved oxygen (O2) is essential for most ocean ecosystems, fuelling organisms'
respiration and facilitating the cycling of carbon and nutrients. Oxygen measurements have …

Carbon isotope ratio of Cenozoic CO2: A comparative evaluation of available geochemical proxies
The carbon isotope ratio (δ13C) of plant material is commonly used to reconstruct the
relative distribution of C3 and C4 plants in ancient ecosystems. However, such estimates …

δ13C evidence that high primary productivity delayed recovery from end-Permian mass extinction
Euxinia was widespread during and after the end-Permian mass extinction and is commonly
cited as an explanation for delayed biotic recovery during Early Triassic time. This anoxic …
