The Importance Of Regional And Landscape Context And Climate Change To Northern Bobwhite Management, Frank R. Thompson Iii
The Importance Of Regional And Landscape Context And Climate Change To Northern Bobwhite Management, Frank R. Thompson Iii
National Quail Symposium Proceedings
Long-term declines in northern bobwhite (Colinus virginianus) in the United States are presumably due to decades of habitat loss or degradation at a national scale. Food and fiber production characterized by replacement of open woodlands and savannas by dense forest, intensification of agriculture, and conversion of native grasslands to nonnative pastures have degraded habitats for most grassland and early successional birds. Declines in bobwhite and associated species occurred within this context at a scale that has overwhelmed wildlife management efforts. However, with understanding of scale and context, managers could sustain these species in some future landscapes. Increasing urbanization …
An Analysis Of The Interactions Between Weather And Land Use On Midwestern Gamebird Populations Using Historical Data: A Preliminary Report, Amanda R. Lipinski, Joseph J. Fontaine
An Analysis Of The Interactions Between Weather And Land Use On Midwestern Gamebird Populations Using Historical Data: A Preliminary Report, Amanda R. Lipinski, Joseph J. Fontaine
National Quail Symposium Proceedings
Concern surrounding species’ abilities to cope with a changing climate and variable land use presents opportunities to look forward toward solutions while investigating historical trends to assess the interaction of land use and weather. Uncertainty surrounding population responses to increased severity and frequency of severe weather associated with climate change presents challenges for making informed management decisions for a suite of already declining bird populations, including huntable populations of socially and economically important game birds, such as northern bobwhite (Colinus virginianus). Historical data are a rich resource for developing a priori hypotheses and models predicting species’ responses to …
Apathy And Concern Over The Future Habitability Of Earth: An Introductory College Assignment Of Forecasting Co2 In The Earth’S Atmosphere, Benjamin J. Burger
Apathy And Concern Over The Future Habitability Of Earth: An Introductory College Assignment Of Forecasting Co2 In The Earth’S Atmosphere, Benjamin J. Burger
Journal on Empowering Teaching Excellence
Non-science, first year regional undergraduate students from rural Utah communities participated in an online introductory geology course and were asked to forecast the rise of CO2 in the Earth’s atmosphere. The majority of students predicted catastrophic rise to 5,000-ppm sometime over the next 3,100 years, resulting in an atmosphere nearly uninhabitable to human life. However, the level of concern the students exhibited in their answers was not directly proportional with their timing in their forecasted rise of CO2. This study showcases the importance of presenting students with actual data and using data to develop student forecasted models. …
Environmental Impacts Of Holiday Gift Giving Of Books And Movies, Benjamin Shaffer
Environmental Impacts Of Holiday Gift Giving Of Books And Movies, Benjamin Shaffer
DePaul Discoveries
This project examines the relationship between gift giving deadweight loss (when the cost of a gift exceeds it value to the recipient) or welfare gain (when the value of a gift to a recipient exceeds the cost of a gift), and the environmental impact of gifts. Surveys of American adults were used to determine the economic welfare losses or gains created by holiday gift giving, comparing gifts of traditional (paper) books and DVD or Blu-ray format movies. Both products showed overall welfare gains as gifts, with books averaging a larger welfare gain than movies. An ANOVA was done to determine …
Possible Evaporite Karst In An Interior Layered Deposit In Juventae Chasma, Mars, Davide Baioni, Mario Tramontana
Possible Evaporite Karst In An Interior Layered Deposit In Juventae Chasma, Mars, Davide Baioni, Mario Tramontana
International Journal of Speleology
This paper describes karst landforms observed in an interior layered deposit (ILD) located within Juventae Chasma a trough of the Valles Marineris, a rift system that belongs to the Tharsis region of Mars. The ILD investigated is characterized by spectral signatures of kieserite, an evaporitic mineral present on Earth. A morphologic and morphometric survey of the ILD surface performed on data of the Orbiter High Resolution Imaging Science Experiment (HiRISE) highlighted the presence of depressions of various shapes and sizes. These landforms interpreted as dolines resemble similar karst landforms on Earth and in other regions of Mars. The observed karst …
Rethinking Our Global Coastal Investment Portfolio, Erin Mccreless, Michael W. Beck
Rethinking Our Global Coastal Investment Portfolio, Erin Mccreless, Michael W. Beck
Journal of Ocean and Coastal Economics
Coastal gray infrastructure, including roads, bridges, and buildings, is critical for communities, and we invest significantly in it. We also invest in the restoration and maintenance of coastal green infrastructure such as wetlands and reefs, which provide many services and benefits to human communities. However, the relative scale of financial investments in different coastal sectors – that is, our global coastal investment portfolio – remains poorly understood. We identify some of the major sources of funding for coastal green and gray infrastructure globally, including international aid funds; US public and private funds for coastal conservation, restoration and management; and private …
