Amino Acid Uptake in Arbuscular Mycorrhizal Plants

Creator:: Whiteside, Matthew D., Garcia, Maria O., and Treseder, Kathleen K.
Abstract:: We examined the extent to which arbuscular mycorrhizal (AM) fungi root improved the acquisition of simple organic nitrogen (ON) compounds by their host plants. In a greenhouse-based study, we used quantum dots (fluorescent nanoparticles) to assess uptake of each of the 20 proteinaceous amino acids by AM-colonized versus uncolonized plants....

Remotely Incorrect? Accounting for Nonclassical Measurement Error in Satellite Data on Deforestation

Creator:: Alix-Garcia, Jennifer and Millimet, Daniel L.
Abstract:: Research relying on remotely sensed data on land use and deforestation has exploded in recent years. While satellite-based measures have clear advantages in terms of coverage, the presence of measurement error within these products is often overlooked. Here, we detail the econometric implications of these errors when analyzing the determinants...

Weeds as important vegetables for farmers

Creator:: Cruz-Garcia, Gisella S. and Price, Lisa L.
Abstract:: The objective of this study was to investigate the multiple uses and cognitive importance of edible weeds in Northeast Thailand. Research methods included focus group discussions and freelistings. A total of 43 weeds consumed as vegetable were reported, including economic, naturalized, agricultural and environmental weeds. The weedy vegetables varied considerably...

A taxonomic and distributional study of the rhodolith-forming species Lithothamnion muelleri (Corallinales, Rhodophyta) in the Eastern Pacific Ocean

Creator:: Robinson, Nestor M., Hansen, G. I., Fernandez-Garcia, C., and Riosmena-Rodriguez, R.
Abstract:: Lithothamnion rnuelleri is reported for the first time as one of the main components of rhodolith beds along the Eastern Pacific Ocean based on samples from Washington State (USA), Pacific Baja California (Mexico), southern Nicaragua, and Costa Rica. Individual rhodoliths ranged from fruticose to lumpy in morphology, and bi-sporangial, tetrasporangial,...

The effects of changing climate on estuarine water levels: a United States Pacific Northwest case study

Creator:: Parker, Kai, Hill, David, García-Medina, Gabriel, and Beamer, Jordan
Abstract:: Climate change impacts on extreme water levels (WLs) at two United States Pacific Northwest estuaries are investigated using a multicomponent process-based modeling framework. The integrated impact of climate change on estuarine forcing is considered using a series of sub-models that track changes to oceanic, atmospheric, and hydrologic controls on hydrodynamics....

Nano-scale investigation of the association of microbial nitrogen residues with iron (hydr)oxides in a forest soil O-horizon

Creator:: Keiluweit, Marco, Bougoure, Jeremy J., Zeglin, Lydia H., Myrold, David D., Weber, Peter K., Pett-Ridge, Jennifer, Kleber, Markus, and Nico, Peter S.
Abstract:: Amino sugars in fungal cell walls (such as chitin) represent an important source of nitrogen (N) in many forest soil ecosystems. Despite the importance of this material in soil nitrogen cycling, comparatively little is known about abiotic and biotic controls on and the timescale of its turnover. Part of the...

Wildfire spread, hazard and exposure metric raster grids for central Catalonia

Creator:: Alcasena, Fermin J., Ager, Alan A., Salis, Michele, Day, Michelle A., and Vega-Garcia, Cristina
Abstract:: We provide 40 m resolution wildfire spread, hazard and exposure metric raster grids for the 0.13 million ha fire-prone Bages County in central Catalonia (northeastern Spain) corresponding to node influence grid (NIG), crown fraction burned (CFB) and fire transmission to residential houses (TR). Fire spread and behavior data (NIG, CFB...

What the Inbred Scandinavian Wolf Population Tells Us about the Nature of Conservation

Creator:: Räikkönen, Jannikke, Vucetich, John A., Vucetich, Leah M., Peterson, Rolf O., and Nelson, Michael P.
Abstract:: The genetic aspects of population health are critical, but frequently difficult to assess. Of concern has been the genetic constitution of Scandinavian wolves (Canis lupus), which represent an important case in conservation. We examined the incidence of different congenital anomalies for 171 Scandinavian wolves, including the immigrant founder female, born...

Characterizing environmental and spatial variables associated with the incidental catch of olive ridley (Lepidochelys olivacea) in the Eastern Tropical Pacific purse-seine fishery

Creator:: Montero, Jose T., Martinez-Rincon, Raul O., Heppell, Selina S., Hall, Martin, and Ewal, Michael
Abstract:: In the Eastern Tropical Pacific (ETP), a region of high fishing activity, olive ridley (Lepidochelis olivacea) and other sea turtles are accidentally caught in fishing nets with tuna and other animals. To date, the interaction between fishing activity, ocean conditions and sea turtle incidental catch in the ETP has been...

Computational Insights into the Central Role of Nonbonding Interactions in Modern Covalent Organocatalysis

Creator:: Walden, Daniel M., Ogba, O. Maduka, Johnston, Ryne C., and Cheong, Paul Ha-Yeon
Abstract:: Conspectus: The flexibility, complexity, and size of contemporary organocatalytic transformations pose interesting and powerful opportunities to computational and experimental chemists alike. In this Account, we disclose our recent computational investigations of three branches of organocatalysis in which nonbonding interactions, such as C–H···O/N interactions, play a crucial role in the organization...
