Assessing the functional relationship between dung beetle traits and dung removal, burial, and seedling emergence.

open access: yesEcology, 2020
The relationship between biodiversity and ecosystem functioning is often assessed through trait diversity. However, the relationship between traits and functions is typically assumed but seldom tested.

Enhanced Organic Carbon Burial in Sediments of Oxygen Minimum Zones Upon Ocean Deoxygenation

open access: yesFrontiers in Marine Science, 2020
Oxygen minimum zones (OMZs) in the ocean are expanding. This expansion is attributed to global warming and may continue over the next 10 to 100 kyrs due to multiple climate CO2-driven factors. The expansion of oxygen-deficient waters has the potential to

Hot tops, cold bottoms: Synergistic climate warming and shielding effects increase carbon burial in lakes

open access: yesLimnology and Oceanography Letters, 2019
In this article, we challenge the notion that global warming stimulates organic matter mineralization and increases greenhouse gas emissions in lakes via direct temperature effects.

Out Of Place: Stone Architecture And Pastoral Nomadism In Prehistoric Inner Asia [PDF]

open access: yes, 2017
How architecture reflects the configuration of physical and social spaces among prehistoric pastoral nomads is a topic scarcely explored in the archaeology of Inner Asia, not least because the common preconception is that structural remains are not in ...

Early Mississippian ocean anoxia triggered organic carbon burial and late Paleozoic cooling: Evidence from uranium isotopes recorded in marine limestone

open access: yes, 2020
The Early Mississippian (Tournaisian) positive δ13C excursion (mid-Tournaisian carbon isotope excursion [TICE]) was one of the largest in the Phanerozoic, and the organic carbon (OC) burial associated with its development is hypothesized to have ...

Carbon burial over the last four millennia is regulated by both climatic and land use change

open access: yesGlobal Change Biology, 2020
Carbon sequestration by sediments and vegetated marine systems contributes to atmospheric carbon drawdown, but little empirical evidence is available to help separate the effects of climate change and other anthropogenic activities on carbon burial over ...

Preliminary study of biodegradability of starch-based bioplastics using ASTM G21-70, dip-hanging, and Soil Burial Test methods

open access: yesIOP Conference Series: Earth and Environment, 2019
Biodegradability testing methods being used nowadays have many disadvantages; they are time-consuming, inefficient medium used, and too much sample needed to do the test.
