The Impact Of Dams On Nitrogen Cycling In The Messalonskee Stream, Rebecca K. Forgrave

Honors Theses

The Messalonskee Stream in central Maine has five hydroelectric dams on 16.6km. Each dam drastically changes the flow regime of the stream, dividing it into segments with different patterns of sediment settling and organic matter retention. I investigated how these disruptions impact nitrogen cycling, specifically nitrification rates above and below each dam. I expected higher nitrification rates above the dams, where levels of organic matter are higher, and lower rates below the dam where scouring removes organic matter and fine sediment from the streambed. I measured sediment nitrification rates with a nitrapyrin-inhibition assay and potential drivers of nitrification including sediment …

Assessing Resilience In Stressed Watersheds, Kristine T. Nemec, Joana Chan, Christina Hoffman, Trisha L. Spanbauer, Joseph A. Hamm, Craig R. Allen, Trevor Hefley, Donald Pan, Prabhakar Shrestha

Although several frameworks for assessing the resilience of social-ecological systems (SESs) have been developed, some practitioners may not have sufficient time and information to conduct extensive resilience assessments. We have presented a simplified approach to resilience assessment that reviews the scientific, historical, and social literature to rate the resilience of an SES with respect to nine resilience properties: ecological variability, diversity, modularity, acknowledgement of slow variables, tight feedbacks, social capital, innovation, overlap in governance, and ecosystem services. We evaluated the effects of two large-scale projects, the construction of a major dam and the implementation of an ecosystem recovery program, on …

Self-Imposed Length Limits In Recreational Fisheries, Christopher J. Chizinski, Dustin R. Martin, Keith L. Hurley, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

A primary motivating factor on the decision to harvest a fish among consumptive-orientated anglers is the size of the fish. There is likely a cost-benefit trade-off for harvest of individual fish that is size and species dependent, which should produce a logistic-type response of fish fate (release or harvest)as a function of fish size and species. We define the self-imposed length limit as the length at which a captured fish had a 50% probability of being harvested, which was selected because it marks the length of the fish where the probability of harvest becomes greater than the probability of release. …

Panarchy: Theory And Application, Craig R. Allen, David G. Angeler, Ahjond S. Garmestani, Lance H. Gunderson, C. S. Holling

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The concept of panarchy provides a framework that characterizes complex systems of people and nature as dynamically organized and structured within and across scales of space and time. It has been more than a decade since the introduction of panarchy. Over this period, its invocation in peer-reviewed literature has been steadily increasing, but its use remains primarily descriptive and abstract. Here, we discuss the use of the concept in the literature to date, highlight where the concept may be useful, and discuss limitations to the broader applicability of panarchy theory for research in the ecological and social sciences. Finally, we …

Discontinuities, Cross-Scale Patterns, And The Organization Of Ecosystems, Kirsty L. Nash, Craig R. Allen, David G. Angeler, Chris Barichievy, Tarsha Eason, Ahjond S. Garmestani, Nicholas A. J. Graham, Dean Granholm, Melinda Knutson, R. John Nelson, Magnus Nyström, Craig A. Stow, Shana M. Sundstrom

Ecological structures and processes occur at specific spatiotemporal scales, and interactions that occur across multiple scales mediate scale-specific (e.g., individual, community, local, or regional) responses to disturbance. Despite the importance of scale, explicitly incorporating a multi-scale perspective into research and management actions remains a challenge. The discontinuity hypothesis provides a fertile avenue for addressing this problem by linking measureable proxies to inherent scales of structure within ecosystems. Here we outline the conceptual framework underlying discontinuities and review the evidence supporting the discontinuity hypothesis in ecological systems. Next we explore the utility of this approach for understanding cross-scale patterns and the …

Predicted Avian Responses To Bioenergy Development Scenarios In An Intensive Agricultural Landscape, Daniel R. Uden, Craig R. Allen, Rob B. Mitchell, Tim D. Mccoy, Qingfeng Guan

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Conversion of native prairie to agriculture has increased food and bioenergy production but decreased wildlife habitat. However, enrollment of highly erodible cropland in conservation programs has compensated for some grassland loss. In the future, climate change and production of second-generation perennial biofuel crops could further transform agricultural landscapes and increase or decrease grassland area. Switchgrass (Panicum virgatum) is an alternative biofuel feedstock that may be economically and environmentally superior to maize (Zea mays) grain for ethanol production on marginally productive lands. Switchgrass could benefit farmers economically and increase grassland area, but there is uncertainty as to how conversions between rowcrops, …

Introduction: Social-Ecological Resilience And Law, Ahjond S. Garmestani, Craig R. Allen, Craig Anthony Arnold, Lance H. Gunderson

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Environmental law is intimately connected to ecological concepts and understanding. The legal instruments, institutions, and administration of law in the United States are predicated on assumptions that nature is globally stable and that the inherent variability in ecological systems is bounded. This current legal framework is based upon an understanding of ecological systems operating near an equilibrium, or if disturbed, moving back toward an equilibrium. Such assumptions make much current environmental law ill-suited for many pressing environmental issues (Ruhl 1999; Garmestani et al. 2009; Craig 2010; Verchick 2010; Benson and Garmestani 2011). Emerging environmental challenges, such as cross-boundary water governance …

Self-Confidence Of Anglers In Identification Of Freshwater Sport Fish, Christopher J . Chizinski, D. R. Martin, K. L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Although several studies have focused on how well anglers identify species using replicas and pictures, there has been no study assessing the confidence that can be placed in angler’s ability to identify recreationally important fish. Understanding factors associated with low self-confidence will be useful in tailoring education programmes to improve self-confidence in identifying common species. The purposes of this assessment were to quantify the confidence of recreational anglers to identify 13 commonly encountered warm water fish species and to relate self-confidence to species availability and angler experience. Significant variation was observed in anglers selfconfidence among species and levels of self-declared …

Toxicity Of Copper Sulfate And Rotenone To Chinese Mystery Snail (Bellamya Chinensis), Danielle M. Haak, Bruce J. Stephen, Robert A. Kill, Nicholas A. Smeenk, Craig R. Allen, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The Chinese mystery snail (Bellamya chinensis) is a freshwater snail native to Southeast Asia, Japan, and Russia and is currently classified as an invasive species in at least 27 states in the USA. The species tolerates a wide range of environmental conditions, making management of established populations difficult. We tested the efficacy of two traditional chemical treatments, rotenone and copper sulfate, on the elimination of adult Chinese mystery snails in laboratory experiments. All snails (N=50) survived 72-hour exposure to rotenone-treated lake water, and 96% (N=25) survived 72-hour exposure to pre-determined rotenone concentrations of 0.25, 2.5, and 25.0 mg/L. …

Transdisciplinary Application Of Cross-Scale Resilience, Shana M. Sundstrom, David G. Angeler, Ahjond S. Garmestani, Jorge-H. Garcia, Craig R. Allen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The cross-scale resilience model was developed in ecology to explain the emergence of resilience from the distribution of ecological functions within and across scales, and as a tool to assess resilience. We propose that the model and the underlying discontinuity hypothesis are relevant to other complex adaptive systems, and can be used to identify and track changes in system parameters related to resilience. We explain the theory behind the cross-scale resilience model, review the cases where it has been applied to non-ecological systems, and discuss some examples of social-ecological, archaeological/ anthropological, and economic systems where a cross-scale resilience analysis could …

Status Of Native Stream Fishes Within Selected Protected Areas Of The Niobrara River In Western Nebraska, Jonathan J. Spurgeon, Richard H. Stasiak, George R. Cunningham, Kevin L. Pope, Mark A. Pegg

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Lotic systems within the Great Plains are characterized by highly fl uctuating conditions through both space and time. Fishes inhabiting these systems have adopted specifi c life- history strategies to survive in such environments; however, anthropogenic disturbance to prairie streams has resulted in declines and extirpation of many native stream fi shes. Terrestrial protected areas (i.e., parks and reserves) are designated to support native fl ora and fauna and, it is assumed, to provide protection to native fi shes. We assessed the presence and relative abundance of stream fi sh populations within protected areas along the Niobrara River in western …

Habitat Structure And Body Size Distributions: Cross-Ecosystem Comparison For Taxa With Determinate And Indeterminate Growth, Kirsty L. Nash, Craig R. Allen, Chris Barichievy, Magnus Nyström, Nicholas A. J. Graham

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Habitat structure across multiple spatial and temporal scales has been proposed as a key driver of body size distributions for associated communities. Thus, understanding the relationship between habitat and body size is fundamental to developing predictions regarding the infl uence of habitat change on animal communities. Much of the work assessing the relationship between habitat structure and body size distributions has focused on terrestrial taxa with determinate growth, and has primarily analysed discontinuities (gaps) in the distribution of species mean sizes (species size relationships or SSRs). The suitability of this approach for taxa with indeterminate growth has yet to be …

Consuming Fire Ants Reduces Northern Bobwhite Survival And Weight Gain, P. Evans Myers, Craig R. Allen, Hannah E. Birge

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Northern bobwhite quail, Colinus virginianus (L.) (Galliformes: Odontophoridae), population declines are well documented, but pinpointing the reasons for these decreases has proven elusive. Bobwhite population declines are attributed primarily to loss of habitat and land use changes. This, however, does not entirely explain population declines in areas intensively managed for bobwhites. Although previous research demonstrates the negative impact of red imported fire ant (Solenopsis invicta Buren) (Hymenoptera: Formicidae) on northern bobwhites, the mechanisms underlying this effect are largely unknown. To meet the protein demands of early growth and development, bobwhite chicks predominantly consume small insects, of which ants are …

Quantifying Spatial Scaling Patterns And Their Local And Regional Correlates In Headwater Streams: Implications For Resilience, Emma Göthe, Leonard Sandin, Craig R. Allen, David G. Angeler

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The distribution of functional traits within and across spatiotemporal scales has been used to quantify and infer the relative resilience across ecosystems. We use explicit spatial modeling to evaluate within- and cross-scale redundancy in headwater streams, an ecosystem type with a hierarchical and dendritic network structure. We assessed the cross-scale distribution of functional feeding groups of benthic invertebrates in Swedish headwater streams during two seasons. We evaluated functional metrics, i.e., Shannon diversity, richness, and evenness, and the degree of redundancy within and across modeled spatial scales for individual feeding groups. We also estimated the correlates of environmental versus spatial factors …

Winter Survival Strategies Of Benthic Invertebrates In Temporary Habitats In A Northern Minnesota Lake, Cal Oldenburg

Journal of Earth and Life Science

During the winter months in the northern hemisphere, above 40 degrees latitude, a freezing event occurs that can last several months. Some lakes may have large portions of the shallow littoral zone frozen completely solid down into the sediments. Invertebrates affected by these events have developed survival strategies to cope with the harsh environment. The two main strategies for invertebrates in these areas are to either migrate to a different area and recolonize the original area when it becomes available again, or to burrow into the sediments and withstand the freezing. A 1- month study took place on Lake Bemidji …

New Mexico Water Law Capsules, Stephanie Tsosie

Water Matters!

This article contains a list some of the key cases decided in the state and federal courts of New Mexico with very brief descriptions of the rulings. The finalized cases have been arranged by topic. This chapter is intended to be a quick and handy reference guide and not a thorough summary of the facts and law of each case. This year we have also included a list of water law statutes.

Water Conservation, Consuelo Bokum

Water Matters!

New Mexico always has had periods of water shortages, some far more long lasting and devastating than others. As warming temperature and changing weather patterns continue to develop, the likelihood that water shortages—like those felt throughout the state from 2010 through 2013—will occur with greater frequency. These changes can and have caused significant economic and environmental damage, and the risk of more harm will not improve unless we improve our water management significant.

Drought, Adrian Oglesby

Water Matters!

New Mexico is renowned for its high deserts, mild climate, and abundant sunshine. Incidentally, these physical attributes, which make New Mexico so unique and beautiful, are also characteristic of a naturally dry environment. The state has been subjected to severe drought conditions in the past, alternating with times of uncharacteristically high supplies of moisture upon which its population has at times over-relied.

This article will provide various definitions of drought and a short history of drought in New Mexico; discuss impacts of drought on the state’s human water user communities and environment; discuss in brief the priority call and water …

Priority Administration, Ed Merta

Water Matters!

Since the turn of the twenty first century, drought conditions have frequently stricken much of New Mexico. Such intervals of extreme dryness have been a permanent, recurring feature of the state’s climate for at least two thousand years, according to tree ring data and other scientific evidence. Some of these past droughts lasted for decades, exceeding in severity the Dust Bowl of the 1930sand the great New Mexico drought of the 1950s. Today, climate change models indicate that the Southwest will likely become even hotter, potentially making future droughts in New Mexico more extreme. Managing water shortages promises to become …

Active Water Resource Management, Paul Bossert, Gregory C. Ridgley

Water Matters!

For decades, most of the waters of the State of New Mexico have been the subject of water rights adjudications to establish all the water rights. Stream systems and sub-basins geographically define the adjudications. There are twelve active cases. However, complete adjudication of all New Mexico water rights is still many years away. Meanwhile, water use in the state has evolved.New water users increasingly look to acquire existing water rights rather than developing new rights. Decisions on administration, distribution, and redistribution of water have to be made.

It was widely held, though not unanimously, that the State Engineer needed greater …

Domestic Wells, Paul Bossert, Sarah Armstrong

Water Matters!

The domestic well statutes direct that the State Engineer “shall” issue a permit for certain types of temporary or low volume wells, including wells for household use. For the past fifty-five years, the Office of the State Engineer (OSE) has interpreted this to mean that such permits are granted with no evaluation, public notice, or hearing.

Water For New Mexico Rivers, Beth Bardwell, Adrian Oglesby

Water Matters!

The Rio Grande, the Pecos, the Gila, the San Juan, the Canadian—New Mexico’s rivers are synonymous with the state’s culture and natural heritage. New Mexicans overwhelmingly care about the health of the state’s rivers and that includes flows to support fish and river dependent wildlife. Rivers, wetlands, and riparian areas comprise a very small part of our landscape—a mere 1 percent. This 1 percent plays an essential role in renewing the state’s water supply for its two million residents; for sustaining the state’s second largest industry—tourism; for producing food and fiber; and for sustaining New Mexico’s web of life. Eighty …

Inter-Basin Water Transfers, Anne Minard

Water Matters!

Inter-basin water transfers move water from one watershed to another. As droughts constrict the availability of water, and cities grow larger and thirstier, such transfers are increasingly being eyed as a solution. Although inter-basin transfers usually do not increase the overall availability of water in a state, they can move water to where it is needed most. Some of the main proponents of inter-basin transfers are pro-growth city and state governments as the re-allocation of water across watersheds allows for flexibility in planning for future growth.

Navajo-Gallup Water Supply Project, Jerold Widdison, Pat Page

Water Matters!

In March of 2009, the Congress passed and President Obama signed into law the“Omnibus Public Land Management Act of 2009". The Project is a major endeavor for northwestern New Mexico. In one sense,authorization of the project culminates years of work. In another sense, it means the beginning of many additional years of effort. There is much to be done to construct and carry the project forward to reality, including work for the federal government,the State of New Mexico, the Navajo Nation, and the city of Gallup. In view of the Project’s magnitude, this article reviews only its major aspects

The Nambé, Pojoaque, San Ildefonso, And Tesuque Pueblos Settlement, Paul Bossert, Sarah Armstrong

Water Matters!

The “Aamodt case” is a complex, long-running adjudication of water rights in the Pojoaque River watershed northwest of Santa Fe. In 1966,it was filed in federal court as State of New Mexico, ex rel. State Engineer,et al. v. Aamodt, et al. The parties include the State, through the State Engineer, about 5,600 non-Indian claimants, the Pueblos of Nambé, Pojoaque,San Ildefonso, and Tesuque, and governmental entities such as the county of Santa Fe, many acequias, the Pojoaque Valley Irrigation District, and several federal and state agencies.

Taos Pueblo Water Rights Settlement, Paul Bossert, Darcy S. Bushnell

Water Matters!

In November of 2010, the Congress passed the Claims Resolution Act and on December 8, President Obama signed it into law. Title V of the Claims Act, the Taos Pueblo Indian Water Rights Settlement Act, settles the Pueblo portion of the Abeyta case and approves an agreement signed in 2006 by officials from Taos Pueblo, the State of New Mexico, and other interested water rights owners in the Taos area. The settlement act also helps resolve the non-Indian portion of Abeyta. The measure quantifies Taos Pueblo’s water rights and protects the interests of local acequias, the Town of Taos, and …
