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...
Eighth annual report of the United States Geological Survey to the Secretary of the Interior, 1886-1887: Part 1
J. W. Powell
1889, Annual Report 8
The Geological Survey was organized, with Mr. Clarence King as Director, in March, 1879. In March, 1881, Mr. King resigned and the present Director was appointed. From its organization to the present time the Survey has steadily grown as Congress has enlarged its functions and increased its appropriations. During this...
Sketch of paleobotany
Lester Frank Ward
1885, Report, Fifth Annual Report of the Director, 1883-'84
To understand the true force of the facts of paleobotany as arguments for geology it is essential that their full biologic significance be grasped. It has therefore been deemed proper, in this introduction to the several tabular and systematic statements which will make up the bulk of the volume and...
I. Sexual, individual, and geographical variation in leucosticte tephrocotis, II.Geographical variation among North American mammals, especially in respect to size
J. A. Allen
1876, Report, Bulletin of the United States Geological and Geographical Survey of the Territories
Having recently had an opportunity (through the kindness of Professor Baird) of studying with some care the magnificent series of skulls of the North American Mammalia belonging to the National Museum (amounting often to eighty or a hundred specimens of a single species), I have been strongly impressed with the...
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...

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...

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...
Comparative analysis of GPP products estimated from an empirical model and MODIS
Li Zhang, Bruce K. Wylie, Thomas Loveland, Lei Ji
None, Conference Paper, Global priorities in land remote sensing
Carbon-cycle models have uncertainties associated with data inputs, parameters, and model algorithms. The prerequisite for an applicable model is that it should perform at an acceptable level of accuracy and uncertainties should be documented. In this study, we validated the gross primary productivity (GPP) data from a piecewise regression (PWR)...
