Throughout the past century, the Missouri River has been highly modified which has negatively affected the native fish community. Previous research quantified the reduction of several native Cyprinidae species and made several recommendations to aid in recovery. However, these recommendations were not implemented. Therefore, the objective of this paper is to assess the current population trends of eight native cyprinid species and develop the current management objectives. Over 335,000 fish were collected from the Missouri River along Nebraska’s eastern border with mini-fyke nets and otter trawls from 2003 to 2012. Target Cyprinidae species consisted of less than five percent (n …

The Status Of Fishes In The Missouri River, Nebraska: Sauger (Sander Canadensis), Kirk D. Steffensen, Sam Stukel, Dane A. Shuman
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Early fisheries investigation of the Missouri River fish community indicated that Sauger were common throughout Nebraska, including all major Missouri River tributaries. However due to many factors, their current range is restricted to the Missouri River and the lower reaches of a few tributaries. Hesse (1994) recommended listing Sauger as a state endangered species but this recommendation was never implemented. Therefore, the objective of this paper is to reevaluate the current population status of Sauger in the Missouri River along Nebraska’s border. Over 2,100 Sauger have been captured from the Missouri River along Nebraska’s eastern border since 2003. Sauger were …

The Cedar Point Experience, 40 Years Of Field Based, Experiential Learning, Jon Garbisch
DBER Speaker Series
The Cedar Point Experience was born in the summer of 1975. At the urging of several biology faculty UNL leased the Goodall Cedar Point Girlscout Camp and offered a broad range of field based courses exploiting the local environment as their classroom. These instructors also had a strong interest in the area as a base for their own research. Today the UNL Cedar Point Biological Station with a few additional buildings can support around 100 people with full service dining, housing, classroom and lab space.
The instructional model has remained unchanged for the past 40 years. Field based or place …

Spatiotemporal Variation In Flow-Dependent Recruitment Of Long-Lived Riverine Fish: Model Development And Evaluation, Daisuke Goto, Martin J. Hamel, Jeremy J. Hammen, Mathew L. Rugg, Mark A. Pegg, Valery E. Forbes
School of Biological Sciences: Faculty Publications
Abstract Natural flow regimes can play a major role as an overarching ecosystem driver in reproduction and recruitment of riverine fishes. Human needs for freshwater however have altered hydrology of many riverine systems worldwide, threatening fish population sustainability. To understand and predict how spatiotemporal dynamics of flow regimes influence reproductive and recruitment variability, and ultimately population sustainability of shovelnose sturgeon (Scaphirhynchus platorynchus), we develop a spatially explicit (1D) individual-based population model that mechanistically (via energetics-based processes) simulates daily activities (dispersal, spawning, foraging, growth, and survival). With field observations of sturgeon and habitat conditions in a major tributary of …

Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Since 1991, 19 specific black-footed ferret reintroduction projects have been conducted across 8 States, Canada, and Mexico. All five of the first ferret reintroductions (from 1991 to 1996) continue to be occupied by ferrets. The photographs of October 31 and November 1 are the first unequivocal documentation of black-footed ferrets on the Standing Rock Indian Reservation. Ferrets observed on Standing Rock may be dispersals from the nearby Cheyenne River Sioux Indian Reservation to the south. The nearest re-introduction site for ferrets is approximately 20 miles away, in Whitehorse, South Dakota, and the observation of ferrets on Standing Rock could document …

The Status Of Fishes In The Missouri River, Nebraska: Lake Sturgeon (Acipenser Fulvescens), Kirk D. Steffensen, Sam Stukel, Dane A. Shuman
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Lake Sturgeon (Acipenser fulvescens) occurrences in the Missouri River along Nebraska’s eastern border are historically sporadic and rare. Presently, the wild Lake Sturgeon population in this river reach may be extirpated. A Recovery Program initiated by the Missouri Department of Conservation (MDC) has stocked almost 150,000 hatchery-reared Lake Sturgeon into the lower Missouri River at several sites in Missouri. As a result, the number of Lake Sturgeon collected has increased. Since monitoring began in 2003, no Lake Sturgeon have been collected above Gavins Point Dam while 40 fish were collected downstream of Gavins Point Dam. The majority of …

The Status Of Fishes In The Missouri River, Nebraska: Shovelnose Sturgeon (Scaphirhynchus Platorynchus), Kirk D. Steffensen, Sam Stukel, Dane A. Shuman
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
The Shovelnose Sturgeon Scaphirhynchus platorynchus remains the most abundant riverine sturgeon species in North American despite the anthropogenic modifications that have occurred throughout their historic range; however, their populations have declined throughout Nebraska since the construction of Fort Randall and Gavins Point Dams. Therefore, the objective of this study was to present the current status of Shovelnose Sturgeon in the Missouri River along Nebraska’s border. Data was acquired from 2003 to 2012 from all reaches of the Missouri River along Nebraska’s eastern border. Catch rates of Shovelnose Sturgeon increased in a downstream trend and were highest in the reach below …

Papers in Parasitology
At Southern Methodist University campus about 6 miles south of Taos, New Mexico, we recovered tetrathyridia of Mesocestoides in five Peromyscus maniculatus in the summers of 2008 (3 of 129, 0.023%), 2009 (0 of 98, 0%), 2010 (1 of 112, 0.008%), 2011 (0 of 88, 0%), and 2012 (1 of 86, 0.011%). Tetrathyridia from the body cavity of one of the five infected mice were injected into the peritoneal cavity of laboratory white mice, Mus musculus. Our later examination of the laboratory mice revealed heavy infections of tetrathyridia continuing to reproduce asexually. Here we provide important new information on …

En un sábado mágico de marzo, maneje con un estudiante de postgrado hasta el valle central del Platte, al oeste de Grand Island, tanto para ver la migración primaveral de aves acuáticas como la de las grullas grises. Tal vez fue una suerte que yo no estuviera preparado emocionalmente para ver como innumerables grullas salpicaban el cielo de horizonte a horizonte, o girando grácilmente sus cabezas como si estuvieran atrapados en algún torbellino de ultra cámara lenta, su vibrato produce una cadencia descendente como la música de un coro aviar angelical.

Temperature Alters Food Web Body-Size Structure, Jean P. Gibert, John P. Delong
Temperature Alters Food Web Body-Size Structure, Jean P. Gibert, John P. Delong
School of Biological Sciences: Faculty Publications
The increased temperature associated with climate change may have important effects on body size and predator– prey interactions. The consequences of these effects for food web structure are unclear because the relationships between temperature and aspects of food web structure such as predator–prey body-size relationships are unknown. Here, we use the largest reported dataset for marine predator–prey interactions to assess how temperature affects predator–prey body-size relationships among different habitats ranging from the tropics to the poles. We found that prey size selection depends on predator body size, temperature and the interaction between the two. Our results indicate that (i) predator–prey …
Cercyonis Pegala Agawamensis (Satyridae): A New Butterfly Subspecies From The Coastal Salt Marshes Of The Northeastern United States Of America, Matthew D. Arey, Alex Grkovich
Cercyonis Pegala Agawamensis (Satyridae): A New Butterfly Subspecies From The Coastal Salt Marshes Of The Northeastern United States Of America, Matthew D. Arey, Alex Grkovich
The Taxonomic Report of the International Lepidoptera Survey
A new subspecies of the Common Wood Nymph (Cercyonis pegala) from the New England coastline in the northeastern region of the United States is described on the basis of phenotype, behavior, habitat, seasonality, flight period, and phenology. Agawamensis is univoltine as in all pegala. The newly described subspecies occurs almost entirely in coastal salt marshes and estuarine meadows, quite atypical as understood for Cercyonis pegala. The newly described subspecies agawamensis predominately prefers and occurs within large open salt marshes but can also be found in similar habitat along smaller tidal rivers, coastal inlets and streams
A Case Of Sympatric Celastrina Ladon (Cramer), Celastrina Lucia (W. Kirby) And Celastrina Neglecta (Edwards) (Lycaenidae: Polyommatinae) In Northern Virginia, With Additional Records Of C. Lucia In Virginia, Harry Pavulaan
The Taxonomic Report of the International Lepidoptera Survey
A case of fully sympatric Celastrina ladon, C. lucia, and early spring brood C. neglecta is documented at a site in northern Virginia. Observations indicate that all three species occupy the same habitat, fly during the same flight period and utilize the same hostplant with no evidence of hybridization. C. ladon and C. lucia are obligate univoltines while C. neglecta is multivoltine. A later flight (second brood) of Celastrina neglecta at the same site utilizes eriophyid mite-induced leaf galls on the very same host tree species. Additional Virginia records of C. lucia are documented.

Assessing Landscape Constraints On Species Abundance: Does The Neighborhood Limit Species Response To Local Habitat Conservation Programs?, Christopher F. Jorgensen, Larkin A. Powell, Jeffrey J. Lusk, Andrew A. Bishop, Joseph J. Fontaine
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Landscapes in agricultural systems continue to undergo significant change, and the loss of biodiversity is an ever-increasing threat. Although habitat restoration is beneficial, management actions do not always result in the desired outcome. Managers must understand why management actions fail; yet, past studies have focused on assessing habitat attributes at a single spatial scale, and often fail to consider the importance of ecological mechanisms that act across spatial scales. We located survey sites across southern Nebraska, USA and conducted point counts to estimate Ring-necked Pheasant abundance, an economically important species to the region, while simultaneously quantifying landscape effects using a …

Western Massasauga (Sistrurus Tergeminus): Species Conservation Assessment, Melissa J. Panella, Brent D. Johnson
Nebraska Game and Parks Commission: Publications
The primary goal in development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the Western Massasauga (Sistrurus tergeminus) as a Tier I at-risk species. Provided are some general management recommendations regarding Western Massasaugas. Conservation practitioners will need to use professional judgment to make specific management decisions based on objectives, location, and a multitude of variables. This resource was designed to share available knowledge of this at-risk species that will aid in the decision-making process or …
Harvest Incentives: A Tool For Managing Aquatic Invasive Species, Bob Wiltshire, Nathan Stone, Marshall Meyers, Bill Hyatt, Lori Williams, Jason Goldberg, Susan Pasko, Leah Elwell
Harvest Incentives: A Tool For Managing Aquatic Invasive Species, Bob Wiltshire, Nathan Stone, Marshall Meyers, Bill Hyatt, Lori Williams, Jason Goldberg, Susan Pasko, Leah Elwell
National Invasive Species Council
Conclusion
The success of any harvest incentive program to address aquatic invasive species will depend upon numerous biological, socioeconomic, and legal considerations. Programs that encourage harvest may be a successful management tool in targeting small, distinct populations; in high priority areas within a larger invasion; or they may play a supplementary role within larger control programs. Their use, however, will require careful review, planning, and monitoring to ensure success and that they do not unintentionally lead to further spread of invasive species, cause additional harm to native species, or waste valuable resources.
Diversity And Ecology Of Host-Seeking Mosquitoes In Irrigated Agro-Ecosystems Of Clay County, Nebraska, Alister K. Bryson
Diversity And Ecology Of Host-Seeking Mosquitoes In Irrigated Agro-Ecosystems Of Clay County, Nebraska, Alister K. Bryson
Department of Entomology: Dissertations, Theses, and Student Research
In the United States, Nebraska has the third highest incidence of human West Nile virus (WNV). Since WNV was first detected in the state in 2002, 3,422 confirmed cases and 57 deaths have been reported. Irrigated agro-ecosystems, which have been associated with elevated WNV incidences in other states, are prevalent in Nebraska. The objectives of this investigation were to 1) characterize mosquito abundance and diversity in irrigated agro-ecosystems, and 2) evaluate associations of two primary vectors of WNV, Culex tarsalis and Culex pipiens, with irrigation methods (sprinkler vs. surface) and crop type (corn vs. soybean). Investigations were conducted …
Response Of Large River Fishes To A Prolonged High Water Event In The Missouri River, Nebraska, Nicholas Paul Hogberg
Response Of Large River Fishes To A Prolonged High Water Event In The Missouri River, Nebraska, Nicholas Paul Hogberg
School of Natural Resources: Dissertations, Theses, and Student Research
Regulation and modification of large rivers to accommodate human uses have been a root cause of freshwater biodiversity declines. The Missouri River is among the most drastically-altered large river systems in North America, with a series of mainstem impoundments in the upper watershed altering flow characteristics downstream, and channelization throughout the lower river homogenizing instream habitat and reducing off-channel habitat. Precipitation events during the winter and spring 2010-2011 caused flooding of the greatest magnitude and duration since reservoir completion. The large magnitude and long duration of this flood made it unlike any flood in recent history and provided a unique …
Accuracy Or Precision: Implications Of Sample Design And Methodology On Abundance Estimation, Lucas K. Kowalewski
Accuracy Or Precision: Implications Of Sample Design And Methodology On Abundance Estimation, Lucas K. Kowalewski
School of Natural Resources: Dissertations, Theses, and Student Research
Estimation of population size by spatially replicated counts (point-count method) has been used for many large-scale animal-monitoring programs, yet its application in aquatic environments has been limited. Multiple site-specific estimates of abundance can be averaged and combined with covariate data to predict total abundance across an area of interest. Covariate data also provide an understanding of the relationship between abundance and habitat use, which is a fundamental interest of many animal-population investigations. Design of sampling scenarios for point-count population-estimate surveys can influence the accuracy and precision of the population estimate. The first objective of this study was to examine how …
Body Size And Species Richness Changes In Glyptosaurinae (Squamata: Anguidae) Through Climatic Transitions Of The North American Cenozoic, Sara Elshafie
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
Poikilothermic vertebrates offer excellent climate proxies based on relationships between environment and measurable variables such as body size and species richness. Relationships of these variables in lizards to environmental transitions over long time scales are poorly understood. Here I show that patterns of body size and species richness in a lizard clade, Glyptosaurinae (Squamata: Anguidae), correspond to known histories of paleotemperatures through the Cenozoic of North America. Glyptosaurines have the richest fossil record among North American Cenozoic lizards and exhibit a wide range of skull sizes. In order to estimate body size for glyptosaurines and other fossil anguids, I collected …

Patch Burn‐Grazing: An Annotated Bibliography, Rajeeva Voleti, Stephen L. Winter, Sherry Leis
Patch Burn‐Grazing: An Annotated Bibliography, Rajeeva Voleti, Stephen L. Winter, Sherry Leis
School of Natural Resources: Faculty Publications
Patch burn‐grazing is a rangeland management strategy that exploits the attraction of grazing animals to recently burned areas in order to achieve management objectives. When fire is applied to a landscape in a patchy manner, leaving some patches unburned, the resulting grazing animal activity, forage utilization, and animal impact are patchily distributed within that landscape as well. Areas that have been recently burned tend to be characterized by the highest levels of grazing animal activity while areas that have gone the longest without burning tend to be characterized by the lowest levels of grazing animal activity. This can be advantageous …

Angler Effort And Catch Within A Spatially Complex System Of Small Lakes, Christopher J. Chizinski, Dustin R. Martin, Kevin L. Pope, Tony J. Barada, Jeffrey J. Schuckman
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Spatial layout of waterbodies and waterbody size can affect a creel clerk’s ability to intercept anglers for interviews and to accurately count anglers, which will affect the accuracy and precision of estimates of effort and catch. This study aimed to quantify angling effort and catch across a spatially complex system of19 small (<100 ha) lakes, the Fremont lakes. Total (±SE) angling effort (hours) on individual lakes ranged from 0 (0) to 7,137 (305). Bank anglers utilized 18 of the 19 lakes, and their mean (±SE) trip lengths(hours) ranged from 0.80 (0.31) to 7.75 (6.75), depending on the waterbody. In contrast, boat anglers utilized 14 of the 19 lakes, and their trip lengths ranged from 1.39 (0.24) to 4.25 (0.71), depending on the waterbody. The most sought fishes, as indexed by number of lakes on which effort was exerted, were anything (17 of 19 lakes), largemouth bass Micropterus salmoides (15 of 19 lakes), and channel catfish Ictalurus punctatus (13 of 19 lakes). Bluegill Lepomis machrochirus, crappie Pomoxis spp., and largemouth bass were caught most frequently across the lakes, but catch rates varied considerably by lake. Of the1,138 parties interviewed, most parties (93%) visited …100>
