Accumulation of radiocarbon in ancient landscapes: A small but significant input of unknown origin (Nature Communications, 2023-05-08)The persistence of organic carbon (C) in soil is most often considered at timescales ranging from tens to thousands of years, but the study of organic C in paleosols (i.e., ancient, buried soils) suggests that paleosols ...

(Nature Research, 2021-01-12)The drying power of air, or vapour pressure deficit (VPD), is an important measurement of potential plant stress and productivity. Estimates of VPD values of the past are integral for understanding the link between rising ...

(Cambridge University Press, 2022-04)The production of meltwater from glacier ice, which is exposed at the margins of land ice during the summer, is responsible for a large proportion of glacier mass loss. The rate of meltwater production from glacier ice is ...

(Nature Research, 2021-10)Nimravids were the first carnivorans to evolve saberteeth, but previously portrayed as having a narrow evolutionary trajectory of increasing degrees of sabertooth specialization. Here I present a novel hypothesis about the ...

(2011)Data on depth to calcic horizon in paleosols of the northern Appalachians for tetrapod bones and trackways, as well as fossil tree remains. These data were collected to establish a paleoclimatic time series for Devonian ...

(University of Oregon, 2016-04)Paleotemperature and paleoprecipitation over the past 40 m.yr. can be inferred from the degree of chemical weathering and depth of carbonate nodules in paleosols of Oregon, Montana, and Nebraska. Paleosol records show ...

(2012-05-02)This report summarizes the data generated from a long-term effort to perform continued and consistent monitoring of goshawk nest sites on the Malheur National Forest in eastern Oregon from 1992 to 2010. This compilation ...

(2010-09-29)Athough over a hundred species of fossil aplodontoids have been described since the extant species, Aplodontia rufa (the mountain beaver), was first described by Rafinesque in 1817, a thorough survey of the relationships ...
