Potentials and limitations for estimating daytime ecosystem respiration by combining tower-based remote sensing and carbon flux measurements

Creator:: Hilker, Thomas, Hall, Forrest G., Coops, Nicholas C., Black, Andrew T., Jassal, Rachhpal, Mathys, Amanda, and Grant, Nicholas
Abstract:: Vegetation carbon uptake and respiration constitute the largest carbon cycle of the planet with an annual turnover in the order of 120 GT. Currently, neither ecosystem carbon uptake (through photosynthesis) nor ecosystem carbon release (through respiration) can be measured directly during the daytime. Instead, flux-tower measurements rely on nighttime respiration...

Maize Metabolic Network Construction and Transcriptome Analysis

Creator:: Monaco, Marcela K., Sen, Taner Z., Dharmawardhana, Palitha D., Ren, Liya, Schaeffer, Mary, Naithani, Sushma, Amarasinghe, Vindhya, Thomason, Jim, Harper, Lisa, Gardiner, Jack, Cannon, Ethalinda K.S., Lawrence, Carolyn J., Ware, Doreen, and Jaiswal, Pankaj
Abstract:: A framework for understanding the synthesis and catalysis of metabolites and other biochemicals by proteins is crucial for unraveling the physiology of cells. To create such a framework for Zea mays L. subsp. mays (maize), we developed MaizeCyc, a metabolic network of enzyme catalysts, proteins, carbohydrates, lipids, amino acids, secondary...

An inducible kras[superscript v]¹² transgenic zebrafish model for liver tumorigenesis and chemical drug screening

Creator:: Nguyen, Anh Tuan, Emelyanov, Alexander, Koh, Chor Hui Vivien, Spitsbergen, Jan M., Parinov, Serguei, and Gong, Zhiyuan
Abstract:: Because Ras signaling is frequently activated by major hepatocellular carcinoma etiological factors, a transgenic zebrafish constitutively expressing the kras(V12) oncogene in the liver was previously generated by our laboratory. Although this model depicted and uncovered the conservation between zebrafish and human liver tumorigenesis, the low tumor incidence and early mortality...

A simple tool for estimating throughfall nitrogen deposition in forests of western North America using lichens

Creator:: Root, Heather T., Geiser, Linda H., Fenn, Mark E., Jovan, Sarah, Hutten, Martin A., Ahuja, Suraj, Dillman, Karen, Schirokauer, David, Berryman, Shanti, and McMurray, Jill A.
Abstract:: Anthropogenic nitrogen (N) deposition has had substantial impacts on forests of North America. Managers seek to monitor deposition to identify areas of concern and establish critical loads, which define the amount of deposition that can be tolerated by ecosystems without causing substantial harm. We present a new monitoring approach that...

Integrating satellite observations and modern climate measurements with the recent sedimentary record: An example from Southeast Alaska

Creator:: Addison, Jason A., Finney, Bruce P., Jaeger, John M., Stoner, Joseph S., Norris, Richard D., and Hangsterfer, Alexandra
Abstract:: Assessments of climate change over time scales that exceed the last 100 years require robust integration of high-quality instrument records with high-resolution paleoclimate proxy data. In this study, we show that the recent biogenic sediments accumulating in two temperate ice-free fjords in Southeast Alaska preserve evidence of North Pacific Ocean...

Seasonal variation of photosynthetic model parameters and leaf area index from global Fluxnet eddy covariance data

Creator:: Groenendijk, M., Dolman, A. J., Ammann, C., Arneth, A., Cescatti, A., Dragoni, D., Gash, J. H. C., Gianelle, D., Gioli, B., Kiely, G., Knohl, A., Law, B. E., Lund, M., Marcolla, B., van der Molen, M. K., Montagnani, L., Moors, E., Richardson, A. D., Roupsard, O., Verbeeck, H., and Wohlfahrt, G.
Abstract:: Global vegetation models require the photosynthetic parameters, maximum carboxylation capacity (V[subscript cm]), and quantum yield (alpha) to parameterize their plant functional types (PFTs). The purpose of this work is to determine how much the scaling of the parameters from leaf to ecosystem level through a seasonally varying leaf area index...

Causes of genome instability: the effect of low dose chemical exposures in modern society

Ivana, Singh, Neetu, Vaccari, Monica, Van Schooten, Frederik J., Valverde, Mahara, Woodrick, Jordan, Zhang, Luoping, van Larebeke, Nik, Kirsch-Volders, Micheline, and Collins, Andrew R.
Abstract:: Genome instability is a prerequisite for the development of cancer. It occurs when genome maintenance systems fail to safeguard the genome’s integrity, whether as a consequence of inherited defects or induced via exposure to environmental agents (chemicals, biological agents and radiation). Thus, genome instability can be defined as an enhanced...

Composition and provenance of terrigenous organic matter transported along submarine canyons in the Gulf of Lion (NW Mediterranean Sea)

Creator:: Pasqual, Catalina, Goñi, Miguel A., Tesi, Tommaso, Sanchez-Vidal, Anna, Calafat, Antoni, and Canals, Miguel
Abstract:: Previous projects in the Gulf of Lion have investigated the path of terrigenous material in the Rhone deltaic system, the continental shelf and the nearby canyon heads. This study focuses on the slope region of the Gulf of Lion to further describe particulate exchanges with ocean’s interior through submarine canyons....

The need to breed crop varieties suitable for organic farming using wheat, tomato and broccoli as examples: A review

Creator:: Lammerts van Bueren, E. T., Jones, S. S., Tamm, L., Murphy, K. M., Myers, J. R., Leifert, C., and Messmer, M. M.
Abstract:: It is estimated that more than 95% of organic production is based on crop varieties that were bred for the conventional high-input sector. Recent studies have shown that such varieties lack important traits required under organic and low-input production conditions. This is primarily due to selection in conventional breeding programmes...

Chronology and Geochemistry of Lavas from the Nazca Ridge and Easter Seamount Chain: an ∼30 Myr Hotspot Record

Creator:: Ray, Jyotiranjan S., Mahoney, John J., Duncan, Robert A., Ray, Jyotisankar, Wessel, Paul, and Naar, David F.
Abstract:: The Easter Seamount Chain and Nazca Ridge are two of the most conspicuous volcanic features on the Nazca plate. Many questions about their nature and origin have remained unresolved because of a lack of geochronological and geochemical data for large portions of both chains. New ⁴⁰Ar⁻³⁹Ar incremental heating age determinations...
