A Conceptual Model To Facilitate Amphibian Conservation In The Northern Great Plains,
2012
Northern Prairie Wildlife Research Center
A Conceptual Model To Facilitate Amphibian Conservation In The Northern Great Plains, David M. Mushet, Ned H. Euliss Jr., Craig A. Stockwell
Great Plains Research: A Journal of Natural and Social Sciences (through 2013)
As pressures on agricultural landscapes to meet worldwide resource needs increase, amphibian populations face numerous threats including habitat destruction, chemical contaminants, disease outbreaks, wetland sedimentation, and synergistic effects of these perturbations. To facilitate conservation planning, we developed a conceptual model depicting elements critical for amphibian conservation in the northern Great Plains. First, we linked upland, wetland, and landscape features to specific ecological attributes. Ecological attributes included adult survival; reproduction and survival to metamorphosis; and successful dispersal and recolonization. Second, we linked ecosystem drivers, ecosystem stressors, and ecological effects of the region to each ecological attribute. Lastly, we summarized information on …
Water And Energy Balance Response Of A Riparian Wetland To The Removal Of Phragmites Australis,

Water And Energy Balance Response Of A Riparian Wetland To The Removal Of Phragmites Australis, Phillip Mykleby
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
Vegetation and climate both play integral roles in water availability, particularly for arid to semi-arid regions. Changes in these variables can lead to extreme shortages in water for regions that rely on water for crop irrigation (i.e., the Great Plains). The objective of this study is to evaluate the impacts of vegetation on water availability in the Republican River basin in central Nebraska. Decreases in streamflow have been observed in the river basin for many years and, as a result, an invasive riparian plant species (Phragmites australis) is being removed in an effort to reduce evapotranspiration and reclaim …

Coarse Woody Debris In A Tropical Rainforest In North Queensland, Australia: Relationships With Stand Structure And Disturbance, Nadine Rea
Independent Study Project (ISP) Collection
Coarse woody debris (CWD) refers to the woody material on the forest floor, including fallen stems, large branches, coarse roots, wood pieces, and standing dead trees (snags) (Harmon et al. 1986). CWD is an essential but often overlooked aspect of ecosystems. It plays many key ecosystem roles and is instrumental in overall ecosystem functionality. While a piece of CWD decomposes, it provides key habitat for many different species, minimizes soil erosion, affects soil development, stores nutrients and water, and influences the global carbon cycle (Harmon and Hua 1991). In some forests, CWD can exist on the forest floor for hundreds …

Organic Cacao Farming In Transamazônica: An Assessment Of Sustainable Livelihood Development, Stephanie Cesario
Independent Study Project (ISP) Collection
Cacao production is growing in the newly opened forest frontiers of the Trans- Amazonian Highway in central Pará, the second biggest producer region in Brazil. This region has recently witnessed the growth of some of the first organic cocoa cooperatives in the country, initially formed in 2006. Cacao presents a unique option for agricultural livelihoods, because grows well in its native habitat under the shade of Amazon forest species, and there is a growing market demand for cocoa. This study aims to assess the organic certification’s effects on tree diversity and cocoa production in this Amazon frontier, together indicating sustainable …
Régulations De L’Usage Et De La Possession De Terre: Exploration De L'Efficacité Des Règles Officielles Concernant La Gestion De Terre Et Perceptions Des Lois Par Les Habitants D’Andranomena Dans La Région Menabe, Ben Armstrong
Independent Study Project (ISP) Collection
Autour d’Andranomena, un village qui se trouve près de Morondava dans la Région Menabe, il y a encore des terres non cultivées couvertes d’herbes sauvages ou de forets. Mais avec l’accroissement de la population dû au taux de natalité et de l’immigration, il y a de plus en plus de pressions pour trouver de la terre nouvelle.
Cette recherche de terrain se passe avec deux processus parallèles: le premier est la demande de titres domaniaux auprès de l’Etat effectuée par l’intéressé et le second est la validation de la possession de terre avec la connaissance locale de la personne qui …

Fourteen Years Of Sustainable Charcoal: The Case Of Ankitsakalaninaomby, Dan Raudonis
Independent Study Project (ISP) Collection
All over the world, different sources of energy are harnessed by populations looking to fulfill their needs, be it electricity, heating, or cooking. In Madagascar, fuel wood and wood charcoal provide the bulk of daily energy needs – for over 85% of the population they are the only available sources of domestic energy (GREEN-Mad 6). These two sources provide a cheap alternative to other fuels such as natural gas, which can be more than three times as expensive as charcoal (GREEN-Mad 51). In an impoverished country such as Madagascar, where 90% of the population live on less than two US …

Implications For Old-Field Restoration: Diversity And Abundance Of Arbuscular Mycorrhizal Fungi In Soils Of Restored York Gum (Eucalyptus Loxophleba Subsp. Loxophleba) Sites Vs. Remnants., Jessica Wong
Independent Study Project (ISP) Collection
Arbuscular mycorrhizal fungi (AMF) may be critical to the restoration of ecosystem function in old-fields. Whether the diversity of the plant community is promoted by the AMF community or is the driving force of AMF diversity is unknown. We investigated two questions in the context of old-field restoration in southwestern Australia: 1) Does restoration of the plant community achieve the restoration of AMF and 2) Is AMF species diversity and abundance influenced by the plant species composition? Our study sites were located in the Ridgefield Experiment in the University of Western Australia’s “Future Farm”. Soil samples were collected from beneath …

Fifty-one fishermen in the coastal villages of Kizimkazi Dimbani and Jambiani were interviewed to discover the current state of fishing in these areas. Each area has its own Village Fishermen Committees and those committees were also a subject of interest, interviewing their members as well as Fishery Department Officials to gain an understanding of how the committees function and their success. Results of fishermen interviews revealed a large number of differences between Kizimkazi Dimbani and Jambiani. Village Fishermen Committees were well attended by participants in both villages and seem to function as strong institutions within the communities studied. Kizimkazi Dimbani …

New Approaches To The Green Revolution: Successes, Failures And New Rice For Africa, Maia S. Woluchem
Independent Study Project (ISP) Collection
The nature of worldwide food insecurity is staggering, with thirteen percent of the world’s population currently malnourished. The situation is particularly dire in Sub- Saharan Africa, where 265 million people face hunger daily, with 30 to 50 million dying yearly. Solutions to the problem are often unsustainable, save a select few. Once such attempt, coined the Green Revolution, garnered both praise and notoriety through its relatively successful transformation of Southeast Asia in the 1960’s. Aimed at increasing food production, the project focused on small-holder farmers and their acquisition of more productive inputs such as high-yield seeds, fertilizers and pesticides. African …

Today coffee has become one of the most popular beverages in the world and is cultivated in many countries. However, in recent years many areas of production, for example in the province of Loja, Ecuador in the valley of Vilcabamba, many are experiencing a threat in the form of a small Coleoptera species. Hypothenemus hampei, also known as la broca de café, passes the majority of its life cycle within the coffee berries and in the process of reproduction and colonization it destroys the bean that makes the beverage. This destruction of the bean no only affects the consumer, …

West Of Eden: Resource Wars And Nature-Cultures In The American West, Scout Calvert
University of Nebraska-Lincoln Libraries: Faculty Publications
The richness and variety of the western landscape is what is at stake in hot political contests for the resources of the West: much of this public land is available to economic activity, including for mining, grazing, logging, and recreation. These uses threaten to outpace the land’s ability to renew these resources along with others, like air and water. Now in the first decade of the millennium with a new environmental awareness emerging partly from media coverage of global warming and peak oil, The American West at Risk offers a wide-ranging look at the degradation of the environment in the …

Global Monthly Water Scarcity: Blue Water Footprints Versus Blue Water Availability, Arjen Y. Hoekstra, Mesfin Mekonnen, Ashok K. Chapagain, Ruth E. Mathews, Brian D. Richter
Daugherty Water for Food Global Institute: Faculty Publications
Freshwater scarcity is a growing concern, placing considerable importance on the accuracy of indicators used to characterize and map water scarcity worldwide. We improve upon past efforts by using estimates of blue water footprints (consumptive use of ground- and surface water flows) rather than water withdrawals, accounting for the flows needed to sustain critical ecological functions and by considering monthly rather than annual values. We analyzed 405 river basins for the period 1996–2005. In 201 basins with 2.67 billion inhabitants there was severe water scarcity during at least one month of the year. The ecological and economic consequences of increasing …

The Water Footprint Of Humanity, Arjen Y. Hoekstra, Mesfin Mekonnen
Daugherty Water for Food Global Institute: Faculty Publications
This study quantifies and maps the water footprint (WF) of humanity at a high spatial resolution. It reports on consumptive use of rainwater (green WF) and ground and surface water (blue WF) and volumes of water polluted (gray WF). Water footprints are estimated per nation from both a production and consumption perspective. International virtual water flows are estimated based on trade in agricultural and industrial commodities. The global annual average WF in the period 1996–2005 was 9,087 Gm3 ∕y (74% green, 11% blue, 15% gray). Agricultural production contributes 92%. About one-fifth of the global WF relates to production for export. …

Ecosystem Services: The Making Of A Metaphor We Live (?) By, Richard B. Norgaard
Systems Science Friday Noon Seminar Series
What started as a humble metaphor to help us think about our relation to nature has become integral to how we are addressing the future of humanity and the course of biological evolution. The metaphor of nature as a stock that provides a flow of services is insufficient for the difficulties we are in or the task ahead. Indeed, combined with the mistaken presumption that we can analyze a global problem within a partial equilibrium economic framework and reach a new economy project-by-project without major institutional change, the simplicity of the stock-flow framework blinds us to the complexity of the …

The Steady-State Economy As A Solution To The World’S Problems: A Theoretical Examination Of The Greatest Environmental Problem Facing Human Society, Brianna L. Besch
The Macalester Review
This paper is a theoretical exploration of the questioning, if you were given a magic power to solve one, and only one, of the worlds problem outlined by a classic environmental author, which would you solve, and why? While the field of environmental studies is relatively new, since the publishing of Malthus’ An Essay on the Principles of Population environmental scholars have been debating what should be considered the greatest environmental problem facing humanity. This paper explains how the creation of a steady-state economy to replace our current economic system, as described by Herman Daly, offers a holistic solution to …

Agriculture Futures: Potential Rural Land Uses On The Palusplain, Rodney Safstrom, Nicolyn Short Dr
Resource management technical reports
The purpose of this project was to identify agricultural land use options and opportunities within the Serpentine–Jarrahdale and Murray Shires, with particular focus on the Palusplain wetland section. The report will contribute to the Department of Planning’s natural resource management plan for the region and guide development of regional and local planning strategies. Historically, the Palusplain was a slowly moving, interconnected, seasonal wetland system with areas of higher ground. Extensive clearing and drainage occurred in the late 1800s through to the mid-1900s to facilitate agriculture; however, agriculture has been found to be a major contributor of nutrients to the system. …
