Land Use And Water Supply, Susan Kelly, Joanne Hilton

Water Matters!

As New Mexico grows and develops, there is a continuing increase in water demand and the need to provide additional supplies. Recent studies estimate the current population of the State to be about two million people, and the population is expected to grow to approximately 3,400,000 by 2050. Regional water plans project water demands for 16 regions within New Mexico. The total projected new water use associated with population growth—the public water supply and associated commercial sectors, exclusive of agriculture, mining, or other industries—ranges from 280,000 to 380,000 acre-feet per year of new water supply needed in the next 40 …

Promiscuous Mating In Feral Pigs (Sus Scrofa) From Texas, Usa, Johanna Delgado-Acevedo, Angeline Zamorano, Randy W. Deyoung, Tyler A. Campbell, David G. Hewitt, David B. Long

United States Department of Agriculture Wildlife Services: Staff Publications

Context. Feral pigs represent a significant threat to agriculture and ecosystems and are disease reservoirs for pathogens affecting humans, livestock and other wildlife. Information on the behavioural ecology of feral pigs might increase the efficiency and effectiveness of management strategies.

Aims. We assessed the frequency of promiscuous mating in relation to oestrous synchrony in feral pigs from southern Texas, USA, an agroecosystem with a widespread and well established population of feral pigs. An association between multiple paternity of single litters and synchrony of oestrous may indicate alternative mating strategies, such as mateguarding.

Methods. We collected gravid sows at …

Spawning-Related Movements Of Barred Sand Bass Paralabrax Nebulifer, In Southern California: Interpretations From Two Decades Of Historical Tag And Recapture Data, E. T. Jarvis, Christi Linardich, C. F. Valle

Biological Sciences Faculty Publications

During the 1960s and 1990s, the California Department of Fish and Game tagged 8,634 barred sand bass in southern California, and 972 fish (11%) were recaptured. Tag returns suggest barred sand bass are transient aggregate spawners that form spawning aggregations consisting of both resident and migrant individuals. Spawning residency at a historic spawning location was estimated by the frequency of returns over time; most same-year returns (82%, n  =  141) were recaptured within a 7 to 35-day period. The maximum recapture distance was 92 km. The average (± SD) non-spawning season recapture distance from peak spawning season tagging locations was …

2010 Piscataqua Region Comprehensive Conservation And Management Plan (Ccmp), Piscataqua Region Estuaries Partnership

Concentrating Solar Power Commercial Application Study: Reducing Water Consumption Of Concentrating Solar Power Electricity Generation, U.S. Department Of Energy

Publications (E)

This report discusses potential methods to reduce water consumption associated with CSP. Four main concentrating solar power technologies are described in this report: parabolic troughs, linear Fresnel, power towers, and dish/engine. Parabolic troughs are the most commercially available technology. Linear Fresnel and power tower technologies are presently being planned as commercial plants, but none have yet been built in the U.S. The first three of these technologies use the heat collected from the sun to power conventional Rankine steam cycles, similar to those used for coal and nuclear plants. Steam cycle power plants require cooling to function (cooling is needed …

An Assessment Of Sea Turtle Nesting Behavior In Relation To Hurricane- And Restoration-Induced Beach Morphodynamics, Tonya Michele Long

Electronic Theses and Dissertations

Coastal habitats are highly dynamic and vulnerable to landscape-level disturbances such as storms and restoration projects. Along the east coast of Florida these areas are particularly valuable as they provide significant nesting habitat for two sea turtle species, the threatened loggerhead (Caretta caretta) and the endangered green turtle (Chelonia mydas). This coast was heavily impacted by three major hurricanes in 2004 and in some areas by large restoration projects in 2005. Recent remote sensing methods allow for broad evaluation of the shoreline and thus the ability to assess sea turtle nesting habitat at a landscape scale. I collected nesting data …

Caretakers Of The Garden Of Delight And Discontent: Adirondack Narrative, Conflict, And Environmental Virtue, Eric Richard Holmlund

Antioch University Dissertations & Theses

This dissertation concerns a widely recognized natural area, New York's Adirondack Park, that serves both as an international model for conservation and as a context for persistent conflict over natural resources, space, wealth and esthetics. It employs narrative inquiry as a method to examine the sources and the function of narratives or stories explaining the history and the present status of social groups in the Park. Narrative theorists maintain that we borrow from such socially circulating narratives to craft our own identities, and then repeat them until we believe them, almost without regard for the factual basis in history or …

Participatory Planning For A Promised Land: Citizen-Led, Comprehensive Land Use Planning In New York’S Adirondack Park, Ann Hope Ruzow Holland

Antioch University Dissertations & Theses

New York’s Adirondack Park is internationally recognized for its biological diversity. Greater in size than Yellowstone, Everglades, Glacier, and Grand Canyon National Park combined, the Adirondacks are the largest protected area within the Northern Appalachian/Acadian Eco-Region and within the contiguous United States. Ecologists, residents of the Park, and others are concerned about rapid land use change occurring within the borders of the Park. Almost half of the six million acres encompassed by the Park boundary is privately-owned, where 80% of land use decisions fall within the jurisdiction of local governments. The comprehensive planning process of one such local government, the …

Designing Payments For Ecosystem Services, James Salzman

Faculty Scholarship

This Policy Series by James Salzman brings attention to a rapidly developing phenomenon—payments for ecosystem services (PES).

Salzman, the Samuel F. Mordecai Professor of Law and the Nicholas Institute Professor of Environmental Policy at Duke University, explains when and where ecosystem services can be provided by voluntary markets rather than government actions. The key to understanding how PES work is rooted in the basis of any voluntary market transaction—gains from trade. One party agrees to take action because another party offers an incentive. Both parties benefit. A beekeeper, for example, brings her hives to an orchard to provide pollination services …

Rethinking Biodiversity Conservation Effectiveness And Evaluation In The National Protected Areas Systems Of Tropical Islands: The Case Of Jamaica And The Dominican Republic, Suzanne Mae Camille Davis

Theses and Dissertations (Comprehensive)

Island conservation theory and practice with regard to conservation of tropical terrestrial biodiversity in protected areas systems has yet to be adequately addressed in conservation literature. This knowledge gap is identified as a key contributor to the adoption of scientific principles for in situ biodiversity conservation, and “universal” conservation and protected area management paradigms that are unsuitable for island contexts and geographical scale. The underlying assumption is that “universal” concepts of biodiversity conservation, protected areas management, and evaluation of their effectiveness are transferable to the ecological and socio-economic contexts of tropical islands. The expected outcome of this knowledge transfer is …

Archaeological Evidence For Resilience Of Pacific Northwest Salmon Populations And The Socioecological System Over The Last ~7,500 Years, Sarah K. Campbell, Virginia L. Butler

Anthropology Faculty Publications and Presentations

Archaeological data on the long history of interaction between indigenous people and salmon have rarely been applied to conservation management. When joined with ethnohistoric records, archaeology provides an alternative conceptual view of the potential for sustainable harvests and can suggest possible social mechanisms for managing human behavior. Review of the ~7,500-year-long fish bone record from two subregions of the Pacific Northwest shows remarkable stability in salmon use. As major changes in the ecological and social system occurred over this lengthy period, persistence in the fishery is not due simply to a lack of perturbation, but rather indicates resilience in the …
