This paper examines long-term eddy covariance data from 18 European and 17 North American and Asian forest, wetland, tundra, grassland, and cropland sites under nonwater- stressed conditions with an empirical rectangular hyperbolic light response model and a single layer two light-class carboxylase-based model. Relationships according to ecosystem functional type are demonstrated between empirical and physiological parameters, suggesting linkages between easily estimated parameters and those with greater potential for process interpretation. Relatively sparse documentation of leaf area index dynamics at flux tower sites is found to be a major difficulty in model inversion and flux interpretation. Therefore, a simplification of the …

Extensions Of Local Domains With Trivial Generic Fiber, William Heinzer, Christel Rotthaus, Sylvia Wiegand

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We consider injective local maps from a local domain R to a local domain S such that the generic fiber of the inclusion map R -> S is trivial, that is P R (0) for every nonzero prime ideal P of S. We present several examples of injective local maps involving power series that have or fail to have this property. For an extension R -> S having this property, we give some results on the dimension of S; in some cases we show dim S = 2 and in some cases dim S = 1.

Vegetative Characteristics Of Pronghorn Bed Sites In Wind Cave National Park, South Dakota, Christopher N. Jacques, Jonathan A. Jenks, Jaret D. Sievers, Daniel E. Roddy

The Prairie Naturalist

Much of the previous literature on pronghorn (Antilocapra americana) fawns has focused on fawn mortality (Beale 1978, Barrett 1984, Gregg et al. 2001) and social behavior (Kitchen 1974, Autenrieth and Fichter 1975, Bromley 1977). Selection of bed sites by pronghorn fawns is a major factor affecting fawn survival (Bromley 1978, Barrett 1981, O'Gara et al. 1986, VanSchmus 1990) because adequate cover is a crucial component of fawn bed site selection (Autenrieth 1984). Alldredge et al. (1991) reported that fawns selected dense shrub cover but avoided the most-dense cover in sagebrush-steppe communities in southcentral Wyoming while Tucker and Gamer …

The Prairie Naturalist

Adult female Microtus ochrogaster and M. pennsylvanicus displayed interspecific territorial behavior in a bluegrass site in Illinois. We concluded that within a site, interspecific territorial behavior might be a factor in non-synchronous population fluctuations characteristic of the two species.

Woodland Bird Use Of In-Channel Islands In The Central Platte River, Nebraska, William C. Scharf

The Prairie Naturalist

Recapture data showed woodland obligate birds from riparian habitats made substantial use of thinly vegetated, adjacent small islands in the Platte River. During the bird nesting and spring migration seasons of 200 I through 2004, there were 4,360 individuals of 90 species captured on both mainland and in: hannel island sites. Island locafion captures totaled 595 individuals of 47 species )etween 2002 and 2004. Islands formerly were considered inconsequential for coraging and nesting of passerines. My study substantiated passerine use of Islands and provided a rationale for additional consideration of islands for migration and nesting management. Assemblages of bird species …

Mallard Brood Movements In The Canadian Prairie Parklands, Garnet H. Raven, Todd W. Arnold, David W. Howerter, Llwellyn M. Armstrong

The Prairie Naturalist

We radiotracked 308 mallard (Anas platyrhynchos) broods from hatching until 30 days of age Oij 15 study areas located throughout the Canadian Prairie Parklands to examine patterns of variation in movement frequency and distance. Broods moved an average of 350 m from nests to first wetlands (SO = 390), with 94% of broods moving less than I km. After leaving the nest, broods had a 23% probability of moving to a new wetland each day, but movement probability was a complex function of study area, hatch date, and ducking age, with younger and earlier-hatched broods exhibiting greater movement …

Partial Characterization Of Two Moderately Halophilic Bacteria From A Kansas Salt Marsh, Aileen M. Johnson, Lance R. Thurlow, Sam R. Zwenger, Eric T. Gillock

The Prairie Naturalist

Two bacterial species were isolated from a salt marsh located on privately owned land in Russell County, Kansas. Water samples from the saIt marsh were streaked for isolation on tryptic soy agar supplemented with 12 % NaCI. Visual scanning of the plates revealed two prominent colony types. The two colony types were subcultured repeatedly until axenic cultures were obtained. 80th of these organisms were shown to be moderately halophilic. The organisms were characterized partially by fatty acid methyl ester analysis, 16S rRNA sequencing, and scanning electron microscopy. These studies revealed that the bacteria previously were unreported members of genera Marinococcus …

Fisheries Research Report No.159 - A 12-Month Survey Of Recreational Estuarine Fishing In The South Coast Bioregion Of Western Australia During 2002/03, C.B. Smallwood, N. R. Sumner

Fisheries Research Reports

The Recreational Fisheries Program of the Department of Fisheries, Western Australia, has a strategic plan to conduct comprehensive creel surveys of recreational fishing in each of the state’s marine bioregions (Penn et al., 2003). These bioregions are the West Coast, Gascoyne, Pilbara/ Kimberley and South Coast (Figure 1). To record and monitor changes in recreational catch and fishing effort, an integrated approach where all bioregions are to be surveyed on a regular basis was proposed. Until this study, the South Coast was the only bioregion in which a survey of recreational fishing had not been undertaken. Although originally intended to …

Accelerating Adoption Of Fire Science And Related Research, Jamie Barbour

Joint Fire Science Program Research Project Reports

Since its inception in 1998, the Joint Fire Science Program (JFSP) has funded over 350 projects. The Joint Fire Science Program has long recognized that the investments made in wildland fire science need to be accompanied by an emphasis on science interpretation and delivery. Program success is ultimately measured by how well information from research efforts is being conveyed to resource managers and end users, and whether this information is improving management decisions. This project introduced a conceptual model for an adaptive process to improve the delivery of scientific information. We developed this process through these steps: 1. Creating a …

An Automated System For Evaluating Bluesky Predictions Of Smoke Impacts On Community Health And Ecosystems, Robert Solomon

Joint Fire Science Program Research Project Reports

Predictions of smoke impacts on communities and ecosystems are currently being made by the BlueSky smoke forecast system; providing real-time predictions of surface smoke concentrations from prescribed fire, wildfire, and agricultural burn activities. Currently operational in the Pacific Northwest, BlueSky has already a demonstrated success regarding what inter-agency collaboration can accomplish. A critical component of BlueSky that needed to be addressed was the development of an automated verification system to evaluate predicted impacts from smoke on communities and ecosystems. A verification system is necessary because land managers need to evaluate their burn decisions against potential National Ambient Air Quality Standard …

Atmospheric Fire Risk (Haines Index) In A Changed Climate, Julie Winkler, Brian Potter

Joint Fire Science Program Research Project Reports

Previous studies of wildland fire potential under a perturbed climate have focused on potential changes in near-surface atmospheric parameters (e.g., temperature, humidity, and precipitation) and vegetation changes. However, above-ground atmospheric conditions, such as atmospheric stability, also play a critical role in fire behavior, especially for larger fires. This study employed the widely-used Haines Index as a measure of above-ground conditions relevant to wildland fire and investigated the potential changes in the Haines Index over the next 100 years. The analysis is based on simulations from the most recent version of the National Center for Atmospheric Research (NCAR) Community Climate System …

Developing An Analysis And Planning Framework For District-Level Fuels Treatment Projects (Final Project Report), Alan Ager

Joint Fire Science Program Research Project Reports

Widespread fuel reduction programs have been initiated in many parts of the USA in response to a growing threat of wildland fire. Urban encroachment, fuels buildup from fire suppression, and drought all have been linked to increasing wildfire frequency and severity. Developing effective mitigation strategies is a challenging problem, especially on vast tracts of federally-managed wildlands in the western U.S. Fuel reduction activities on Federal lands are generally difficult to plan and implement due to cost, public expectations, and land management regulations. State of the art wildfire modeling is frequently required to demonstrate the benefits of fuels reduction treatments and …

Joint Fire Science Program Research Project Reports

The objective of this paper is to present recommendations for fuels treatments in ponderosa pine forests in the Southwest, Colorado Front Range, and Black Hills of South Dakota. We have synthesized existing knowledge from the peer-reviewed literature and administrative studies and acquired local knowledge through a series of discussions with fuels treatment practitioners. We describe specific treatments, the circumstances under which they can be applied, and treatment effects. We provide recommendations related to where, how, and how often fuels treatments may be prescribed to achieve desired outcomes. Desired outcomes address social, political, economic, and ecological factors.

Soil Response To Season And Interval Of Prescribed Fire In A Ponderosa Pine Forest Of The Blue Mountains, Oregon, D. Zabowski, W. G. Thies, J. Hatten, A. Ogden

Joint Fire Science Program Research Project Reports

Soil properties were examined at a season of burn and burn interval study located in the Malheur National for responses to prescribed burns used to reduce fuel loads and wildfire hazard. Prescribed burn comparisons included spring vs. fall burning, with either one 15-year interval burn or two 5-year interval burns of each season. Results showed that major change to soil organic matter was a reduction in the amount of O horizon. The percent bare ground increased with both spring and fall burning and was highest with multiple burns, indicating a loss of O horizon cover. There was also a decrease …

Effects Of Fuel Treatments And Wildfire On The Avifauna Of The Pine Rockland Ecosystem In Southern Florida., John D. Lloyd, Gary L. Slater, Skip Snow, James R. Snyder

Joint Fire Science Program Research Project Reports

The response of plants and animals in the pine forests of southern Florida to variation in fire and hydrological regimes remains inadequately described, hindering the ability of resource managers to manipulate fire and water to achieve desired ecological outcomes. In this study, we took advantage of natural variation in two measures of fire history (the number of days since last fire and the number of times an area had been burned during the previous ten years) and one measure of hydrology (water table elevation) to explore how plants, breeding birds, and wintering birds in slash-pine (Pinus elliottii var. densa) forests …
