How Can Linguistics Help to Structure a Multidisciplinary Neo Domain such as Exobiology? [PDF]

open access: yesBIO Web of Conferences, 2014
This chapter examines the contribution that corpus linguistics can make towards stabilising definitions within exobiology. By using the clues provided by natural language processing tools, linguists build an interpretation of contexts and try to show how

Assessing the Effect of Large Igneous Provinces on Global Oceanic Redox Conditions Using Non‐traditional Metal Isotopes (Molybdenum, Uranium, Thallium)

open access: yesGeophysical Monograph Series, Page 305-323., 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.

Thallium Isotopes Across the Smithian-Spathian Boundary: Evidence for Anoxia Throughout Most of the Early Triassic. [PDF]

open access: yesGeobiology
ABSTRACT Following the largest known Phanerozoic extinction, the end‐Permian mass extinction, the Early Triassic is often considered an interval of slow biotic recovery. During this time, the minor Smithian‐Spathian extinction occurred, further delaying the biotic recovery of this epoch.

Red to Green: A Lipid Biomarker Record of Tonian-Ediacaran Algae in Siberia. [PDF]

open access: yesGeobiology
ABSTRACT Multiple lines of evidence point to a major diversification of Eukarya in the late Tonian period, ca. 800–720 Ma ago. Regular steranes, lipid biomarkers primarily sourced from eukaryotes, are first unambiguously reported from multiple sites. Here, we present lipid biomarker stratigraphic records from two drill‐cores from the Lena‐Anabar Basin ...

Generalizing frameworks for sentience beyond natural species

open access: yesAnimal Sentience, 2022
Crump et al. (2022) offer a well-argued example of an essential development: a rigorous framework for assessing sentience from the perspective of moral concern over an agent’s welfare.
