Chemical composition of igneous rocks expressed by means of diagrams, with reference to rock classification on a quantitative chemico-mineralogical basis
J. P. Iddings
1903, Professional Paper 18
The value of graphical methods for expressing relative quantities has been well established in all kinds of statistical exposition and discussion. Their use in conveying definite conceptions of relative quantities of chemical and mineral components of rocks is becoming more and more frequent, and the value of the results in...

Volume XIII: The tertiary insects of North America
Samuel H. Scudder
1890, Report, Report of the United States Geological Survey of the Territories
That creatures so minute and fragile as insects, creatures which can so feebly withstand the changing seasons as to live, so to speak, but a moment, are to be found fossil, engraved, as it were, upon the rocks or embedded in their hard mass, will never cease to be a...

Predicting species distributions: unifying model selection and scale optimization for multi-scale occupancy models
Bryan S. Stevens, Courtney J. Conway
None, Ecosphere (10)
Geographic distributions are a basic component of a species’ ecology, and predicting distributions is a fundamental task of conservation and resource management. Reliable prediction depends on identification of appropriate scales of effect for environmental data, and scale-optimization techniques are thus desirable to identify optimal scales for predictor variables. Recent statistical...
Characterizing the interface between wild ducks and poultry to evaluate the potential of transmission of avian pathogens
Julien Cappelle, Nicolas Gaidet, S. A. Iverson, John Y. Takekawa, Scott H. Newman, Bouba Fofana, Marius Gilbert
None, International Journal of Health Geographics (10)
BackgroundCharacterizing the interface between wild and domestic animal populations is increasingly recognized as essential in the context of emerging infectious diseases (EIDs) that are transmitted by wildlife. More specifically, the spatial and temporal distribution of contact rates between wild and domestic hosts is a key parameter for modeling...
Using indirect methods to constrain symbiotic nitrogen fixation rates: A case study from an Amazonian rain forest
C.C. Cleveland, B.Z. Houlton , C Neill, Sasha C. Reed, Y Wang, A.R. Townsend
None, Biogeochemistry (99) 1-13
Human activities have profoundly altered the global nitrogen (N) cycle. Increases in anthropogenic N have had multiple effects on the atmosphere, on terrestrial, freshwater and marine ecosystems, and even on human health. Unfortunately, methodological limitations challenge our ability to directly measure natural N inputs via biological N fixation (BNF)-the largest natural source...

An empirical algorithm for estimating agricultural and riparian evapotranspiration using MODIS Enhanced Vegetation Index and ground measurements of ET. II. Application to the lower Colorado River, U.S.
R. Scott Murray, Pamela L. Nagler, Kiyomi Morino, Edward P. Glenn
None, Remote Sensing (1) 1125-1138
Large quantities of water are consumed by irrigated crops and riparian vegetation in western U.S. irrigation districts. Remote sensing methods for estimating evaporative water losses by soil and vegetation (evapotranspiration, ET) over wide river stretches are needed to allocate water for agricultural and environmental needs. We used the Enhanced Vegetation...

None, Remote Sensing of Environment (113) 1473-1485
The delta of the Colorado River in Mexico supports a rich mix of estuarine, wetland and riparian ecosystems that provide habitat for over 350 species of birds as well as fish, marine mammals, and other wildlife. An important part of the delta ecosystem is the riparian corridor, which is supported by agricultural return flows and...
Modeling of wave driven circulation and water quality in nearshore environments
Craig Jones, Stephen J. Angster
None, Conference Paper, Proceedings of the 2008 world environmental and water resources congress
In order to investigate the effects of nearshore discharges of water quality degrading substances and bacteria in coastal environments, models capable of predicting nearshore circulation due to local wave and tide conditions are required. One of the larger challenges to nearshore coastal modeling is accurately reproducing nearshore circulation due to...
Relationship between remotely-sensed vegetation indices, canopy attributes and plant physiological processes: What vegetation indices can and cannot tell us about the landscape
Edward P. Glenn, Alfredo R Huete, Pamela L. Nagler, Stephen G. Nelson
None, Sensors (8) 2136-2160
Vegetation indices (VIs) are among the oldest tools in remote sensing studies. Although many variations exist, most of them ratio the reflection of light in the red and NIR sections of the spectrum to separate the landscape into water, soil, and vegetation. Theoretical analyses and field studies have shown that...

Jeff M. Markle, Robert A. Schincariol, J.H. Sass, John W. Molson
None, Soil Science Society of America Journal (70) 1281-1294
Both hydrologic and thermal transport properties play a significant role in the movement of heat through permeable sedimentary material; however, the thermal conductivity is rarely characterized in detailed spatial resolution. As part of a study of the movement of thermal plumes through a sand and gravel aquifer, we have constructed...

Shuguang Liu, William A. Reiners, Kenneth G. Gerow, David S Schimel, Michael Keller
None, Conference Paper
The most important requirements for large-area environmental modeling are a tight integration between models and data, and a close match of the spatial scale at which the model is developed with the scale at which the model is to be applied. To better match the scale of data with that...
