Agenda: Outdoor Recreation: Promise And Peril In The New West, University Of Colorado Boulder. Natural Resources Law Center, Colorado. Bureau Of Land Management

Outdoor Recreation: Promise and Peril in the New West (Summer Conference, June 8-10)

Co-sponsored by the Natural Resources Law Center and the Colorado Bureau of Land Management.

The conference will explore several components of the “promise and peril” of the ongoing outdoor recreation explosion. The conference will begin on the morning of June 8 with a series of introductory presentations designed to place the outdoor recreation movement in a useful historical and socioeconomic context. This material will be followed in the afternoon session by a discussion of environmental impacts of outdoor recreation, recognizing that the diversity and magnitude of impacts is as broad as the industry itself. This discussion will be followed on …

Form, Function, And Evolution In Skulls And Teeth Of Bats, Patricia W. Freeman May 1998

Form, Function, And Evolution In Skulls And Teeth Of Bats, Patricia W. Freeman

School of Natural Resources: Faculty Publications

Bats provide a model system for tracking change from the primitive mammalian tooth pattern to patterns indicating the more-derived food habits of carnivory, nectarivory, frugivory, and sanguinivory. Whereas microchiropteran bats show all these transitions, megachiropterans illustrate an alternative pattern concerned only with frugivory and nectarivory. In microchiropterans, it is likely that carnivory nectarivory, frugivory, and sanguinivory are all derived from a dilambdodont insectivorous tooth pattern. Megachiropterans are troublesome because they appear as nectarivores or frugivores without a clear relationship to ancestral taxa.

The nature of the food item and how teeth respond to that item evolutionarily is an issue I …

Amphibians And Reptiles [Of The Sand Hills], Patricia W. Freeman May 1998

Amphibians And Reptiles [Of The Sand Hills], Patricia W. Freeman

School of Natural Resources: Faculty Publications

Of the 60 species of amphibians and reptiles presently known from Nebraska, 27 are found in the Sand Hills and one more is marginal to the east. Fourteen species of the 60 are essentially state wide in distribution, including the Sand Hills, and eight species of reptiles are strongly influenced by the Sand Hills (Lynch, 1985). Of 12 species that occur widely over the moister eastern part of the state, only four extend into the Sand Hills, and one occurs only under the wet conditions along the rivers of the eastern Sand Hills.

Amphibians: Tiger salamander (Ambystoma tigrinum); …

Mammals [Of The Sand Hills], Patricia W. Freeman

School of Natural Resources: Faculty Publications

Of approximately 81 species of mammals present in Nebraska today, 55 occur in the Sand Hills, with an additional three species that are associated only with the Niobrara River. Nebraska as a whole is truly a crossroads for mammals because two-thirds of the species reach their distributional limits in the state (Jones, 1964). Most of these mammals are widespread species or are specific to the grasslands as a whole and are not affected by this sandy zone. Jones (1964) wrote that “only a few mammals are restricted to this area. Mostly it serves to filter western species moving east and, …

This survey was conducted by Nebraska Natural Heritage Program of the Nebraska Game and Parks Commission with funding received from the U.S. Department of the Interior, Bureau of Reclamation, Grand Island office. This agreement was entered into on April 16, 1996. The objective of the agreement was to conduct a survey of a portion of the Loup River basin floodplain corridor for rare plant communities and plant and animal species. This is the final report of that survey. This report includes not only data collected directly as a result of field survey work associated with the project but also previous …

We analyzed the relationship between new ecosystem exchange of carbon dioxide (NEE) and irradiance (as photosynthetic photon flux density of PPFD), using published and unpublished data that have been collected during midgrowing season for carbon balance studies at seven peatlands in North America and Europe. NEE measurements included both eddy-correlation tower and clear, static chamber methods, which gave very similar results. Data were analyzed by site, as aggregated data set for all peatland type (bog, poor fen, rich fen, and all fens) and as a single aggregated data set for all peatlands. In all cases, a fit with a rectangular …


Air Temperature Variations And Rice Productivity In Bangladesh: A Comparative Study Of The Performance Of The Yield And The Ceres-Rice Models, Rezaul Mahmood Mar 1998

Air Temperature Variations And Rice Productivity In Bangladesh: A Comparative Study Of The Performance Of The Yield And The Ceres-Rice Models, Rezaul Mahmood

School of Natural Resources: Faculty Publications

Potential increase in air temperature due to climatic change and inter-annual climatic variability and its impacts on crop productivity is of major concern to crop scientists. A number of physically-based models have been developed and applied to estimate crop–environment relationships. In the present study the performance of two such models (the YIELD and the CERES-Rice) are discussed. These two models are used to estimate boro rice productivity under normal and abnormal climate scenarios in Bangladesh. This study finds that boro rice productivity at Mymensingh predicted by the YIELD is higher than the prediction by the CERES-Rice. Productivity estimates for Barisal …

Climatology Of The Daily Temperature Range Annual Cycle In The United States, Daniel J. Leathers, Michael A. Palecki, David A. Robinson, Kenneth F. Dewey Feb 1998

Climatology Of The Daily Temperature Range Annual Cycle In The United States, Daniel J. Leathers, Michael A. Palecki, David A. Robinson, Kenneth F. Dewey

School of Natural Resources: Faculty Publications

Many researchers are presently interested in detecting long-term trends in annual or seasonal daily temperature range (DTR), and attributing these changes to anthropogenic origins. However, very little work has been done to confirm the mechanisms that are important to determining the long-term average annual cycle of the DTR. Therefore, the focus of this work is to examine the spatial and temporal difference in the DTR average annual cycle across the United States, and to associate the patterns of these cycles with potential causal variables. Three major types of DTR annual cycle exist in the United States: high sun season maximum …

A Build-Out Study Of The Mid-Connecticut Valley Of Massachusetts, Center For Economic Development Jan 1998

A Build-Out Study Of The Mid-Connecticut Valley Of Massachusetts, Center For Economic Development

Center for Economic Development Technical Reports

This is a study of growth potential in seven towns located along an east-west axis in the mid Connecticut River Valley in western Massachusetts. It employs a planning method commonly described as a build-out analysis in which lands are identified that are both physically suitable and available for future development. Zoning regulations, population growth projections, land conservation trends, and other constraints are then used to project different growth scenarios that result in estimations of the number of new residences that can be accommodated over time and the increases in population that would be likely based on those. The results of …

1997 Inventory For Spiranthes Diluvialis Sheviak In Western Nebraska: A Final Report, Volume Ii, Terri Hildebrand

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

This study resulted from an agreement between Nebraska Game and Parks Commission (NGPC) and the United States Fish and Wildlife Service (USFW). After the 1996 discovery of Spiranthes diluvialis, in western Nebraska, NGPC was seeking to determine the extent of the Nebraska population. Information on the wet meadow community of orchid occurrence in Nebraska and eastern Wyoming was needed. This report includes descriptions of communities inventoried, Spiranthes diluvialis populations, and additional species monitored by Nebraska and Wyoming Natural Heritage programs.

Between May and September 1997, potential Spiranthes diluvialis habitat was inventoried for occurrences of the orchid. For all sites …
