Climate response to the 8.2 ka event in coastal California

open access: yesScientific Reports, 2017
A fast-growing stalagmite from the central California coast provides a high-resolution record of climatic changes synchronous with global perturbations resulting from the catastrophic drainage of proglacial Lake Agassiz at ca. 8.2 ka.

Foliar nutrient uptake from dust sustains plant nutrition [PDF]

open access: yesBiogeosciences
Mineral nutrient uptake from soil through the roots is considered the main nutrition pathway for vascular terrestrial plants. Recently, desert dust was discovered as an alternative nutrient source to plants through direct uptake from dust deposited on ...

Isotopic evidence for the source and fate of phosphorus in Everglades wetland ecosystems

open access: yesApplied Geochemistry, 2011
Phosphorus has historically been a limiting nutrient in the Florida Everglades. Increased P loading to the Everglades over the past several decades has led to significant changes in water quality and plant communities. Stormwater runoff that drains agricultural lands and enters the Water Conservation Areas (WCAs) are known to contain elevated levels of

Substrate Characterization of Mycobacterial Kinase PknG Revealing PknG‐KARS‐MAPK Phosphorylation Signaling Axis in Host

open access: yesiMetaMed, EarlyView.
This study employed multi‐omics approaches to investigate the regulatory mechanism of Mycobacterium PknG on host cell processes. We found that host lysine‐tRNA ligase (KARS) is a potential substrate of PknG; and PknG can regulate the immune response by catalyzing the phosphorylation of KARS at T592 and T595 sites, affecting the phosphorylation level in

Responses of ectomycorrhizal fungi to changes in carbon and nutrient availability [PDF]

open access: yes, 2001
Ectomycorrhizal (ECM) fungi may receive 20% of the total C fixed by their host plants and are essential components of host nutrient acquisition. As a consequence of the vast physiological diversity that exists among ECM fungi, changes in community ...

Isotopic Differentiation (δ18OPO4) of Inorganic Phosphorus among Organic Wastes for Nutrient Runoff Tracing Studies: A Summary of the Literature with Refinement of Livestock Estimates for Grand Lake St. Marys Watershed (Ohio)

open access: yesPollutants
The use of stable isotopes, specifically δ18OPO4 ratios, in differentiating potential sources of inorganic phosphorus (e.g., wastewater, septic, wild animals, domesticated animals, livestock, substrates, or commercial fertilizers) to watersheds is a ...

Liebig Review: Essential and Beneficial Elements in the Regulation of Cadmium Uptake and Tolerance in Crop Plants

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Cadmium (Cd2+) contamination in agricultural soils has been reported to pose risks to crop productivity, food safety, and human health. This review synthesizes current knowledge on the mechanisms by which essential (S, Zn, Fe, Mg, K, Ca) and beneficial (Si, Se, rare earth elements) elements mitigate Cd2+ toxicity in plants.

Deglaciation of the Burren glacio‐karst, western Ireland, during Termination 1: Implications for North Atlantic climate and karstification

open access: yesJournal of Quaternary Science, EarlyView.
Abstract The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...
