More than 90% of marine dissolved organic matter (DOM) is biologically recalcitrant. This
recalcitrance has been attributed to intrinsically refractory molecules or to low concentrations …

The Early Eocene Climatic Optimum (EECO) has been characterized as a prolonged warm
event indicated by increased atmospheric pCO2, temperatures, precipitation, and biological …

Marine organic matter is one of Earth's largest actively cycling reservoirs of organic carbon
and nitrogen,. The processes controlling organic matter production and removal are …

To explore cause and consequences of past climate change, very accurate age models
such as those provided by the astronomical timescale (ATS) are needed. Beyond 40 million …

Pronounced transient global warming events between 60 and 50 million years ago have
been linked to rapid injection of isotopically-light carbon to the ocean–atmosphere system,. It …

The ocean's biota sequester atmospheric carbon dioxide (CO2) in part by producing
dissolved organic matter (DOM) that persists in the ocean for millennia. This long-term …

Major fraction of marine dissolved organic matter (DOM) is biologically recalcitrant, however,
the accumulation mechanism of recalcitrant DOM has not been fully understood. Here, we …

Ocean deoxygenation could potentially trigger substantial changes in the composition and
reactivity of dissolved organic matter (DOM) pool, which plays an important role in the global …

Marine dissolved organic matter (DOM) is a large (660 Pg) pool of reduced carbon that is
subject to thermal alteration in hydrothermal systems and sedimentary basins. In natural …

Skippers (Family: Hesperiidae) are a large group of butterflies with ca. 4000 species under
567 genera. The lack of a time-calibrated higher-level phylogeny of the group has precluded …
