Efficacy Of Sunflower Decoy Plots For Blackbird Control And Supplemental Stopover Habitat, Heath M. Hagy, Jon Raetzman, George M. Linz, William J. Bleier
United States Department of Agriculture Wildlife Services: Staff Publications
Wildlife Conservation Sunflower Plots (WCSP) were planted and monitored during a two-year trial/research program to monitor the effect of decoy plots on blackbird use of nearby commercial sunflower and abundance of nonblackbird migratory species within the plots. In the two year evaluation period, in excess of 975 hours were spent by three researchers in the plots monitoring damage, vegetation, and avian use. We used bird numbers, vegetation characteristics, and landuse landscape variables to assess the optimal habitat conditions in and around each decoy plot for luring blackbirds and providing adequate stopover habitat for nonblackbird migrants. In 2004, wetland and shelterbelt …

A Preliminary Review Of Neotropical Primates In The Subsistence And Symbolism Of Indigenous Lowland South American Peoples, Loretta Cormier
A Preliminary Review Of Neotropical Primates In The Subsistence And Symbolism Of Indigenous Lowland South American Peoples, Loretta Cormier
Ecological and Environmental Anthropology (University of Georgia)
This article provides a review of selected literature of nonhuman primates in the subsistence and symbolism of indigenous lowland South American groups. While few works have focused specifically on the relationship between human and nonhuman primates in Amazonia and the surrounding areas, a number of ethnographic works do incorporate information about the roles of monkeys in varied groups. The section on subsistence focuses on the use of primates as food, including preferences, avoidances, and taboos. The section on symbolism focuses on the role of monkeys in myths, folklore, and in delineating the humanity/animality divide.
Review Of Conservation: Linking, Ecology, Economics, And Culture By Monique Borgerhoff Mulder And Peter Coppolillo, David Himmelfarb
Review Of Conservation: Linking, Ecology, Economics, And Culture By Monique Borgerhoff Mulder And Peter Coppolillo, David Himmelfarb
Ecological and Environmental Anthropology (University of Georgia)
Guided by their extensive field experience in conservation research and practice, Monique Borgerhoff Mulder and Peter Coppolillo offer an encompassing introduction to some of the most pervasive and incendiary social and biological science debates concerning biodiversity conservation. As environmental conservation initiatives have expanded throughout the globe in recent decades, scholars primarily from the social sciences have begun to critically examine the often fraught social dynamics of such conservation. This body of work has ignited a series of fierce debates among those with a concern for local peoples who have found themselves marginalized by conservation, those with a concern for rapidly …

The Importance Of Integrative Anthropology: A Preliminary Investigation Employing Primatological And Cultural Anthropological Data Collectionmethods In Assessing Human-Monkey Co-Existence In Bali, Indonesia, James E. Loudon, Michaela E. Howells, Agustin Fuentes
Ecological and Environmental Anthropology (University of Georgia)
This study investigates the interplay between humans (Homo sapiens) and long-tailed macaques (Macaca fascicularis) living in sympatric associations at 11 Hindu temple sites on the island of Bali, Indonesia. Primatological methods were utilized to examine demography, habitat type, and record long-tailed macaque feeding, and ranging behavior. Additionally, interviews and questionnaires were conducted to ascertain Balinese individuals’ perspectives regarding the macaques, local folklores surrounding the macaques, the perceived level of human-macaque overlap, and the degree of crop raiding by the macaques. Ethnographic methods revealed that attitudes toward long-tailed macaques vary, suggesting that human perceptions are determined by religious/local folklores and potential …

Variation In The Response Of Crustacean Zooplankton Species Richness And Composition To The Invasive Predator Bythotrephes Longimanus, Angela L. Strecker, Shelley E. Arnott, Norman D. Yan, Robert Girard
Environmental Science and Management Faculty Publications and Presentations
The predacious invertebrate Bythotrephes longimanus has invaded >90 freshwater lakes in North America. There is some evidence that B. longimanus has a negative effect on summer zooplankton species richness; however, no study has examined the effect of B. longimanus throughout the ice-free season in more than one lake. We visited 10 invaded and 4 reference lakes every 2 weeks from May to September, collecting B. longimanus, crustacean zooplankton, and water chemistry samples. Composite samples were pooled across the study season for each lake. Bythotrephes longimanus significantly reduced cladoceran species richness, diversity, and abundance, and the total zooplankton community also exhibited …

Using Student Generated Qualitative Ecological Models, J. Scott Blackwood, Marion Dresner, Hang-Kwang Luh
Environmental Science and Management Faculty Publications and Presentations
In this activity, students construct qualitative models of an ecosystem and use the models to gain a better understanding of direct and indirect ecological interactions. Qualitative modeling is described for use in two procedures, each with different educational goals and student backgrounds in mind. Part 1 is designed with the non-major or beginning ecology student in mind, and is intended both to improve student understanding of the ecosystem of interest and to provide a framework for the instructor to assess student learning. Part 2 is designed for more advanced students of ecology and involves the use of modeling software (POWERPLAY) …

Since 1922, the Western Association of Fish and Wildlife Agencies (WAFWA) has served as a leader promoting management and protection of fish and wildlife in the western United States and Canada. An organization represented by 17 states and four Canadian provinces, WAFWA has faced the difficult challenge of sifting through the ever-changing societal, economic, political and scientific issues that define natural resource management in a West that has undergone many changes. WAFWA is particularly concerned about mule deer, a species that lives in every North American habitat except for the tropics, arctic and extreme deserts. Mule deer numbers and distribution …
Salinity Controls Phytoplankton Response To Nutrient Enrichment In The Great Salt Lake, Utah, Usa, Amy M. Marcarelli, Wayne A. Wurtsbaugh, O. Griset
Salinity Controls Phytoplankton Response To Nutrient Enrichment In The Great Salt Lake, Utah, Usa, Amy M. Marcarelli, Wayne A. Wurtsbaugh, O. Griset
Watershed Sciences Faculty Publications
To examine how salinity and nutrient supply interact to control phytoplankton community composition, nutrient limitation, and dinitrogen (N2) fixation rates in the Great Salt Lake (Utah, USA), we conducted a series of bioassay experiments with plankton from both Gilbert Bay, where salinities are near 160 g·L–1, and Farmington Bay, where salinities range from 10 to 90 g·L–1. Six-day nutrient addition bioassay experiments showed that the extant phyto plankton communities in both bays were limited by nitrogen (N). However, in 28- to 30-day factorial bioassay experiments in which both salinities and nutrient supply were manipulated, phosphorus stimulated chlorophyll a as much …
Assessment Of Water Quality Trends In The Upper Cumberland River Basin: Focus On Pathogen Impairment, Kentucky Water Resources Institute
Assessment Of Water Quality Trends In The Upper Cumberland River Basin: Focus On Pathogen Impairment, Kentucky Water Resources Institute
KWRRI Research Reports
This project consisted of analyzing existing water quality data for streams in the Upper Cumberland River Basin, with a particular focus on pathogen trends. According to the most recent 303(d) list of Kentucky waters, the majority of streams assessed in the Upper Cumberland Basin are impaired for primary recreational contact as a result of pathogens. The state pathogen standard for primary contact recreation is expressed in a dual form which specifies that the 30-day geometric mean of fecal coliform counts not exceed 200 colonies per 100 mL (on a minimum of five samples) and not more than 20 percent of …
Sauger Population Ecology In Three Missouri River Mainstem Reservoirs, Brian D. S. Graeb
Sauger Population Ecology In Three Missouri River Mainstem Reservoirs, Brian D. S. Graeb
Electronic Theses and Dissertations
Sauger Sander canadensis populations have experienced widespread declines across much of their range. Factors suspected to contribute to these declines include hybridization, exploitation, loss of spawning areas, and general habitat alterations associated with regulated rivers. Several sauger populations within the Missouri River basin are also experiencing similar declines, particularly in the headwaters of Montana, and the lower basin states of Nebraska and Missouri. However, sauger populations in many of the reservoirs in South Dakota (between Montana and the lower basin) have relatively stable populations. Given the paucity of information on factors influencing sauger population ecology in general, and Missouri River …

Inside Global Warming, Roxanne Greitz Miller
Inside Global Warming, Roxanne Greitz Miller
Education Faculty Articles and Research
Over the last 15 years, much attention has been given to global warming, and whether the increase in the Earth's temperature in recent decades threatens the survival of life on Earth. Release of the films The Day After Tomorrow (2004), where North America is rapidly plunged into a new ice age, and An Inconvenient Truth (2006), where Al Gore focuses on the future impacts of global warming, has raised much public and media attention on the subject. As such, it's important that science teachers understand the basics behind the scientific phenomenon, the controversy surrounding the topic, and how to discuss …

Multiple Hypotheses Testing Of Fish Incidence Patterns In An Urbanized Ecosystem, Christopher J. Chizinski, C.L. Higgins, C.E. Shavlik, Kevin L. Pope
Multiple Hypotheses Testing Of Fish Incidence Patterns In An Urbanized Ecosystem, Christopher J. Chizinski, C.L. Higgins, C.E. Shavlik, Kevin L. Pope
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Ecological and evolutionary theories have focused traditionally on natural processes with little attempt to incorporate anthropogenic influences despite the fact that humans are such an integral part of virtually all ecosystems. A series of alternate models that incorporated anthropogenic factors and traditional ecological mechanisms of invasion to account for fish incidence patterns in urban lakes was tested. The models were based on fish biology, human intervention, and habitat characteristics. However, the only models to account for empirical patterns were those that included fish invasiveness, which incorporated speciesspecific information about overall tolerance and fecundity. This suggests that species-specific characteristics are more …

A Framework For Spatial Risk Assessments: Potential Impacts Of Nonindigenous Invasive Species On Native Species, Craig R. Allen, Alan R, Johnson, Leslie Parris
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Many populations of wild animals and plants are declining and face increasing threats from habitat fragmentation and loss as well as exposure to stressors ranging from toxicants to diseases to invasive nonindigenous species. We describe and demonstrate a spatially explicit ecological risk assessment that allows for the incorporation of a broad array of information that may influence the distribution of an invasive species, toxicants, or other stressors, and the incorporation of landscape variables that may influence the spread of a species or substances. The first step in our analyses is to develop species models and quantify spatial overlap between stressor …
Multimodel Inference And The Understanding Of Complexity, Discontinuity, And Normadism, Craig R. Allen, Denis A. Saunders
Multimodel Inference And The Understanding Of Complexity, Discontinuity, And Normadism, Craig R. Allen, Denis A. Saunders
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Nomadism has received surprisingly little attention in the ecological literature, and further work in this area is needed. The results of Woinarski’s reanalysis of our research findings are broadly similar to our own, and they support our original interpretation. However, his presentation is confusing and difficult to interpret.We used an information-theoretic approach to multimodel selection. We a priori defined plausible candidate models relating the variables described in our original paper or Woinarski’s reanalysis to the phenomenon of nomadism. We tested models that investigate nomadism as a function of nectivory, granivory, diet diversity, mixed diet, distance to body mass aggregation edge, …

Firm Size Diversity, Functional Richness, And Resilience, Ahjond S. Garmestani, Craig R. Allen, John D. Mittelstaedt, Craig A. Stow, William A. Ward
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
This paper applies recent advances in ecology to our understanding of firm development, sustainability, and economic development. The ecological literature indicates that the greater the functional richness of species in a system, the greater its resilience – that is, its ability to persist in the face of substantial changes in the environment. This paper focuses on the effects of functional richness across firm size on the ability of industries to survive in the face of economic change. Our results indicate that industries with a richness of industrial functions are more resilient to employment volatility.
Habitat Selection Responses Of Parents To Offspring Predation Risk: An Experimental Test, J. J. Fontaine, T. E. Martin
Habitat Selection Responses Of Parents To Offspring Predation Risk: An Experimental Test, J. J. Fontaine, T. E. Martin
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
The ability of nest predation to influence habitat settlement decisions in birds is widely debated, despite its importance in limiting fitness. Here, we experimentally manipulated nest predation risk across a landscape and asked the question, do migratory birds assess and respond to variation in nest predation risk when choosing breeding habitats? We examined habitat preference by quantifying the density and settlement date of eight species of migratory passerines breeding in areas with and without intact nest predator communities. We found consistently more individuals nesting in areas with reduced nest predation than in areas with intact predator assemblages, although predation risk …
Draft Environmental Assessment For Listing Silver Carp (Hypophthalmichthys Molitrix) As Injurious Wildlife Under The Lacey Act
National Invasive Species Council
In this environmental assessment, we consider two alternatives for the proposed action to add silver carp (Hypophthalmichthys molitrix) to the list of injurious wildlife under the Lacey Act: 1) no action; and 2) adding all forms (diploid and triploid) of live silver carp, gametes, eggs and hybrids. Three alternatives considered, but dismissed from further analysis were 1) adding all forms of live and dead silver carp, gametes, eggs and hybrids; and 2) adding only diploid (fertile) forms of live silver carp, gametes, eggs and hybrids; and 3) require double-escape proof aquaculture ponds, transport vehicles and containers for typical …

Gray whales Eschrichtius robustus exist as a 2 geographically and genetically distinct populations in the eastern and western North Pacific. Subjected to intensive commercial whaling during the 19th and 20th centuries, the western population presently numbers approximately 100 individuals and is regarded as one of the most endangered baleen whale populations in the world.
Spatial Statistical Models That Use Flow And Stream Distance, Jay M. Ver Hoef, Erin Peterson, David Theobald
Spatial Statistical Models That Use Flow And Stream Distance, Jay M. Ver Hoef, Erin Peterson, David Theobald
United States Department of Commerce: Staff Publications
We develop spatial statistical models for stream networks that can estimate relationships between a response variable and other covariates, make predictions at unsampled locations, and predict an average or total for a stream or a stream segment. There have been very few attempts to develop valid spatial covariance models that incorporate flow, stream distance, or both. The application of typical spatial autocovariance functions based on Euclidean distance, such as the spherical covariance model, are not valid when using stream distance. In this paper we develop a large class of valid models that incorporate flow and stream distance by using spatial …
Cetacean Abundance In Hawaiian Waters Estimated From A Summer/Fall Survey In 2002, Jay Barlow
Cetacean Abundance In Hawaiian Waters Estimated From A Summer/Fall Survey In 2002, Jay Barlow
United States Department of Commerce: Staff Publications
Cetacean abundance is estimated for the U.S. Exclusive Economic Zone (EEZ) around the Hawaiian Islands based on a ship line-transect survey from August to November, 2002. Sighting detection functions are estimated from this and other NOAA research surveys from 1986 to 2002 using a new, multiple-covariate approach. Twenty-four species were seen on this survey, including two species (Fraser’s dolphin [Lagenodelphis hosei] and sei whale [Balaenoptera borealis]) that had not been previously documented to occur in Hawaiian waters. The most abundant large whales are sperm whales (Physeter macrocephalus) and Bryde’s whales (Balaenoptera edeni). The most …
Horizontal Subsurface Flow Constructed Wetlands For On-Site Wastewater Treatment, Boyd C. Hoddinott
Horizontal Subsurface Flow Constructed Wetlands For On-Site Wastewater Treatment, Boyd C. Hoddinott
Master of Public Health Program Student Publications
Horizontal subsurface flow constructed wetlands (SSFCWs) are being used worldwide to treat wastewater from a variety of sources. An extensive literature review was conducted to update the current state of scientific knowledge on the performance of SSFCWs for domestic wastewater treatment. This review documented good treatment efficiency for the five commonly measured parameters (TSS, BOD, nitrogen, phosphorus, and fecal coliforms).
An attempt at a Meta analysis turned up a myriad of problems preventing a proper statistical review. These include lack of adherence to standard methods for effluent analysis, varying metrics for reporting treatment efficiency, variability in the nitrogen species which …
