(A) Plot of D 13 C cc-om values versus MAP measurements for all 18 modern soil series. Also shown is a best-fit polynomial curve correlation to the data set. The D 13 C cc-om values are strongly negatively correlated with mean annual precipitation values up to »36 cm. (B) Plot of D 13 C cc-om values versus MAP measurements for all 16 modern soil series with MAP values less than 36 cm. Also shown is the best-fit linear correlation to the data set.

Paleosol morphology and geochemistry in sedimentary strata have accumulated to produce a high resolution record of Permo-Triassic (PT) paleoclimate and paleoenvironments that spans a large swath of the African continent. This geographically-extensive dataset records changes in climate during a major mass extinction event and time of terrestrial env...

... comparison between measured MAP and D 13 C cc-om values in modern soils shows a strong linear, negative correlation between »8 and 36 cm and »25 and 14%, respectively (Fig. 4A, B). Although there are few data for soils with MAP measure- ments in excess of 36 cm, it appears that D 13 C cc-om values become insensitive to MAP at this point, flattening out around 14-15% (Fig. 4A). The linear, negative correlation between MAP less than 36 cm and D 13 C cc-om has a best-fit parametric cor- relation as ...

Our current understanding of the causes of global extinction risk is mostly informed by the expert knowledge‐based “threats classification scheme” of the IUCN Red List of Threatened Species. Studies based on this dataset came to different conclusions about the relative importance of threats to species, depending on which taxonomic groups and le...
Recent studies indicate that the bulk (80%) of Deccan trap eruptions occurred over a relatively short time interval in magnetic polarity C29r, whereas multi-proxy studies from central and southeastern India place the Cretaceous-Paleogene (K/Pg) mass extinction near the end of this main phase of Deccan volcanism suggesting a cause-and-effect relatio...
The Guadalupian mass extinction took place during the major global environmental changes during Phanerozoic time. Large-scale sea-level fluctuations and a negative shift of δ¹³ C were associated with this crisis. However, the diagenetic or primary origin of the decreased δ¹³ C across the Guadalupian–Lopingian (G–L) boundary and the potential causes...
All cyclidan species represented by existing material are illustrated photographically. New genera within Cyclidae include Ambocyclus new genus; Carabicyclus new genus; Chernyshevine new genus, Litocyclus new genus; and Tazawacyclus new genus with the following new combinations: A.). A neotype is herein designated for Halicyne plana. Each family wi...
Multiple lines of evidence suggest that volcanic and thermogenic gas emanations from the voluminous eruptions of the Central Atlantic Magmatic Province (CAMP) triggered the end‐Triassic mass extinction. However, a comparison of the timing and duration of the biotic and environmental crises with the timing and duration of the magmatic activity is di...
