Research on early warning indicators has generally focused on assessing temporal transitions with limited application of these methods to detecting spatial regimes. Traditional spatial boundary detection procedures that result in ecoregion maps are typically based on ecological potential (i.e. potential vegetation), and often fail to account for ongoing changes due to stressors such as land use change and climate change and their effects on plant and animal communities. We use Fisher information, an information theory-based method, on both terrestrial and aquatic animal data (U.S. Breeding Bird Survey and marine zooplankton) to identify ecological boundaries, and compare our results to traditional …

Effects Of Climate Change And Anthropogenic Modification On A Disturbance-Dependent Species In A Large Riverine System, Sara L. Zeigler, Daniel H. Catlin, Mary Bomberger Brown, James D. Fraser, Lauren R. Dinan, Kelsi L. Hunt, Joel G. Jorgensen, Sarah M. Karpanty Jan 2017

Effects Of Climate Change And Anthropogenic Modification On A Disturbance-Dependent Species In A Large Riverine System, Sara L. Zeigler, Daniel H. Catlin, Mary Bomberger Brown, James D. Fraser, Lauren R. Dinan, Kelsi L. Hunt, Joel G. Jorgensen, Sarah M. Karpanty

School of Natural Resources: Faculty Publications

Humans have altered nearly every natural disturbance regime on the planet through climate and land-use change, and in many instances, these processes may have interacting effects. For example, projected shifts in temperature and precipitation will likely influence disturbance regimes already affected by anthropogenic fire suppression or river impoundments. Understanding how disturbance-dependent species respond to complex and interacting environmental changes is important for conservation efforts. Using field-based demographic and movement rates, we conducted a metapopulation viability analysis for piping plovers (Charadrius melodus), a threatened disturbance-dependent species, along the Missouri and Platte rivers in the Great Plains of North America. …

Plant Uptake And Stream Chemistry Set Global Bounds On Nitrogen Gas Emissions From Humid Tropical Forests, E.N.J. Brookshire, S. Gerber, W. Greene, R.A. Jones, Steven A. Thomas Jan 2017

Plant Uptake And Stream Chemistry Set Global Bounds On Nitrogen Gas Emissions From Humid Tropical Forests, E.N.J. Brookshire, S. Gerber, W. Greene, R.A. Jones, Steven A. Thomas

School of Natural Resources: Faculty Publications

Denitrification and hydrologic leaching are the two major pathways by which nitrogen is lost from the terrestrial biosphere. Humid tropical forests are thought to dominate denitrification from unmanaged lands globally, but there is large uncertainty about the range and key drivers of total N gas emissions across the biome. We combined pantropical measures of small watershed stream chemistry with ecosystem modeling to determine total nitrogen gas losses and associated uncertainty across humid tropical forests. Our calculations reveal that denitrification in soils and along hydrologic flowpaths contributes on average >45% of total watershed N losses. However, when denitrification occurs exclusively in …

Ungulate Predation And Ecological Roles Of Wolves And Coyotes In Eastern North America, John F. Benson, Karen M. Loveless, Linda Y. Rutledge, Brent R. Patterson Jan 2017

Ungulate Predation And Ecological Roles Of Wolves And Coyotes In Eastern North America, John F. Benson, Karen M. Loveless, Linda Y. Rutledge, Brent R. Patterson

School of Natural Resources: Faculty Publications

Understanding the ecological roles of species that influence ecosystem processes is a central goal of ecology and conservation biology. Eastern coyotes (Canis latrans) have ascended to the role of apex predator across much of eastern North America since the extirpation of wolves (Canis spp.) and there has been considerable confusion regarding their ability to prey on ungulates and their ecological niche relative to wolves. Eastern wolves (C. lycaon) are thought to have been the historical top predator in eastern deciduous forests and have previously been characterized as deer specialists that are inefficient predators of …

Daugherty Water for Food Global Institute: Faculty Publications

Crop simulation models are valuable tools for quantifying crop yield response to water, and for devising strategies to improve agricultural water management. However, applicability of the majority of crop models is limited greatly by a failure to provide open-access to model source code. In this study, we present an open-source version of the FAO AquaCrop model, which simulates efficiently water-limited crop production across diverse environmental and agronomic conditions. Our model, called AquaCrop-OpenSource (AquaCrop-OS), can be run in multiple programming languages and operating systems. Support for parallel execution reduces significantly simulation times when applying the model in large geospatial frameworks, for …

Paid To Pump: How A Tax Credit Could Discourage Conservation Of The High Plains Aquifer, S. Polzkill,, A. Stejskal, H. Wilke, Anna Wistrom, Katherine E. B. Gibson, Mindy J. Spiehs, Nicholas Brozovic Jan 2017

Paid To Pump: How A Tax Credit Could Discourage Conservation Of The High Plains Aquifer, S. Polzkill,, A. Stejskal, H. Wilke, Anna Wistrom, Katherine E. B. Gibson, Mindy J. Spiehs, Nicholas Brozovic

Daugherty Water for Food Global Institute: Faculty Publications

In 1965’s United States v. Shurbet case, an irrigator from Texas asserted his claim for a depletion tax deduction for groundwater pumped from the High Plains Aquifer. He argued that the unique conditions of the southern High Plains region - a plateau where the shallow aquifer is recharged only through precipitation at a slow rate - meant the groundwater resource would be depleted in time. The state argued that groundwater was not fundamentally an exhaustible natural deposit, but the Supreme Court concluded the tax deduction was appropriate given the “peculiar” conditions in the area. It was stated the decision was …

Pathways To Increasing Farmer-Led Investments In Sustainable Agricultural Water Management In Sub-Saharan Africa, Douglas J. Merrey, Peter G. Mccornick, Molly C. Nance Jan 2017

Pathways To Increasing Farmer-Led Investments In Sustainable Agricultural Water Management In Sub-Saharan Africa, Douglas J. Merrey, Peter G. Mccornick, Molly C. Nance

Daugherty Water for Food Global Institute: Faculty Publications

Without a transformative leap forward in the use of irrigation, Africa will continue falling short in the struggle to feed its growing population, improve its people’s nutrition, grow its economies, adapt to the impacts of climate change, and eliminate poverty. While Africans must lead this transformation for it to be successful, the international community can help African countries substantially increase the use of more productive and sustainable water management practices and unlock the potential of farmer-led irrigated agriculture. Achieving highly productive irrigated agricultural systems in Africa requires an enabling environment that facilitates the full engagement of farmers, public and private …

Malta : Natural Freshwater Resources, Lisamarie Pereira Jan 2017

Malta : Natural Freshwater Resources, Lisamarie Pereira

Global Public Health

The aim of this paper is to discuss Malta’s struggle with limited natural freshwater resources. Malta currently uses aquifers to obtain natural freshwater. For over a decade, aquifers have been under pressure from over-abstraction. Due to this issue, Malta has not been able to obtain enough natural freshwater for agriculture and basic living. The biggest risk due to over-abstraction is retrieving a smaller volume of freshwater. In Malta’s attempted interventions, the biggest issue is the Maltese government’s misconceptions. The Maltese government believes the country has unlimited natural freshwater resources. Due to this misconception, nothing is being done to actively fix …

Great Plains Geology: A Personal Journey, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

From graduate school in 1962 to now, I achieved my goals and became a geologist and professor, travelling and doing research in the Great Plains and western Central Lowland physiographic provinces, and looking at geology in exotic places like the UK, China, Australia and New Zealand. Fast forward to 2013. I had enough experience and expertise on Great Plains geology by then that I was asked to write a short book of about 35,000 words on the geology of the Great Plains by the director of the Center for Great Plains Studies at the University of Nebraska, Dr. Richard Edwards. …

Land Trust Response To Renewable Energy Siting Challenges In New York, Collin David Adkins Jan 2017

Land Trust Response To Renewable Energy Siting Challenges In New York, Collin David Adkins

Bard Center for Environmental Policy

Energy policies promoting energy independence, grid modernization, climate change mitigation, and clean energy standards are a leading driver of land-use change in the United States. This has resulted in an increased pressure to develop land. The recent focus by states to expand renewable energy poses an interesting challenge to organizations dedicated to conserving open space and natural resources, creating a potential tension between competing “green” goals. In response, The Land Trust Alliance, a national organization supporting over 1,100 member land trusts, has recently set a goal to “empower land trusts to encourage the buildout of renewable energy facilities while steering …

Public Perception Of Environmental Programs In The Sierra Gorda Biosphere Reserve, Landa De Matamoros, Queretaro, Mexico, Danielle Marie Salisbury Jan 2017

Public Perception Of Environmental Programs In The Sierra Gorda Biosphere Reserve, Landa De Matamoros, Queretaro, Mexico, Danielle Marie Salisbury

Bard Center for Environmental Policy

Biological or ecological corridors have recently been sought out as a solution to biodiversity loss due to habitat fragmentation. In eastern Mexico, the Mexican and German governments are collaborating to connect fragmented landscapes and Natural Protected Areas (NPAs) over five states across a Madrean Pine-Oak biodiversity hotspot through the implementation of the Ecological Corridor of the Sierra Madre Oriental (CESMO). One of the ways the CESMO is accomplishing its conservation goals is by extending environmental programs that are currently in place within NPAs to other areas within the corridor, but outside of NPA borders. However, the success of the corridor …

Landscape Features Affecting Northern Bobwhite Predator-Specific Nest Failures In Southeastern Usa, Susan Ellis-Felege, Shannon E. Albeke, Nathan P. Nibbelink, Michael J. Conroy, D. Clay Sisson, William E. Palmer, John P. Carroll Jan 2017

Landscape Features Affecting Northern Bobwhite Predator-Specific Nest Failures In Southeastern Usa, Susan Ellis-Felege, Shannon E. Albeke, Nathan P. Nibbelink, Michael J. Conroy, D. Clay Sisson, William E. Palmer, John P. Carroll

School of Natural Resources: Faculty Publications

Nest predation is a critical component in avian productivity and typically is the leading cause of nest failure for most birds. Several landscape features are thought to drive the behavioral interaction between northern bobwhite (Colinus virginianus; e.g., nest placement) and their predators (e.g., search methods for food acquisition). In order to understand habitat characteristics influencing predation, we studied bobwhite nests using 24-hour near-infrared video cameras. We monitored 675 bobwhite nests with cameras on 3 properties in northern Florida and southern Georgia, USA, during 2000–2006. To test the association between nest failures and specific failure causes with landscape structure, we calculated …
