An Acoustic Monitoring Method For Assessing River Dolphin Presence And Changes In The Context Of Anthropogenic Development, Charles A. Muirhead

Graduate Masters Theses

Populations of river dolphins throughout Asia are in decline as a direct result of intensified anthropogenic activity along river systems. Water development projects, land use change, contamination, and intensified fishing practices are known factors contributing to the probable extinction of the Yangtze river dolphin (Lipotes vexillifer) and declining populations of the South Asian river dolphin (Platanista gangetica spp.), Irrawady dolphin (Orcaella brevirostris), and finless porpoise (Neophocaena a. asiaeorientalis). Although not yet as extensive, river system development in South America is following a similar path as that of Asia, with impacts on dolphin species likely to follow. Currently, the Amazon river …

Quantifying Bee Assemblages And Attractiveness Of Flowering Woody Landscape Plants For Urban Pollinator Conservation, Bernadette M. Mach, Daniel A. Potter

Entomology Faculty Publications

Urban and suburban landscapes can be refuges for biodiversity of bees and other pollinators. Public awareness of declining pollinator populations has increased interest in growing plants that provide floral resources for bees. Various publications and websites list “bee-friendly” plants, but such lists are rarely based on empirical data, nor do they emphasize flowering trees and shrubs, which are a major component of urban landscapes. We quantified bee visitation to 72 species of flowering woody landscape plants across 373 urban and suburban sites in Kentucky and southern Ohio, USA, sampling and identifying the bee assemblages associated with 45 of the most …

Simulating Detection-Censored Movement Records For Home Range Analysis Planning, Lyndsie S. Wszola, Victoria L. Simonsen, Lucía Corral, Christopher J. Chizinski, Joseph J. Fontaine

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Home range estimation is an important analytical method in applied spatial ecology, yet best practices for addressing the effects of spatial variation in detection probability on home range estimates remain elusive. We introduce the R package “DiagnoseHR,” simulation tools for assessing how variation in detection probability arising from landscape, animal behavior, and methodological processes affects home range inference. We demonstrate the utility of simulation methods for home range analysis planning by comparing bias arising from three home range estimation methods under multiple detection scenarios. We simulated correlated random walks in three landscapes that varied in detection probability and constructed home …

Dynamics Of Postfire Aboveground Carbon In A Chronosequence Of Chinese Boreal Larch Forests, Yuan Z. Yang, Wen H. Cai, Jian Yang, Megan White, John M. Lhotka

Forestry and Natural Resources Faculty Publications

Boreal forests store a large proportion of the global terrestrial carbon (C), while wildfire plays a crucial role in determining their C storage and dynamics. The aboveground C (AC) pool is an important component of forest C stocks. To quantify the turning point (transforming from C source to C sink) and recovery time of postfire AC, and assess how stand density affects the AC, 175 plots from eight stand age classes were surveyed as a chronosequence in the Great Xing'an Mountains of Northeast China. Linear and nonlinear regression analyses were conducted to describe postfire AC recovery patterns. The results showed …

Understory Community Assembly Following Wildfire In Boreal Forests: Shift From Stochasticity To Competitive Exclusion And Environmental Filtering, Bo Liu, Han Y. H. Chen, Jian Yang

Forestry and Natural Resources Faculty Publications

Understory vegetation accounts for the majority of plant species diversity and serves as a driver of overstory succession and nutrient cycling in boreal forest ecosystems. However, investigations of the underlying assembly processes of understory vegetation associated with stand development following a wildfire disturbance are rare, particularly in Eurasian boreal forests. In this study, we measured the phylogenetic and functional diversity and trait dispersions of understory communities and tested how these patterns changed with stand age in the Great Xing'an Mountains of Northeastern China. Contrary to our expectation, we found that understory functional traits were phylogenetically convergent. We found that random …

Relationships Among Biodiversity Dimensions Of Birds In Nebraska, Nadejda Mirochnitchenko

School of Natural Resources: Dissertations, Theses, and Student Research

Biological diversity, or biodiversity, is a multi-dimensional concept that can be decomposed to measure information about taxonomic, phylogenetic, and functional variation within communities. Although the dimensions of biodiversity are interrelated, the assumption that measuring one dimension of diversity can inform about patterns in another dimension does not necessarily follow from theory or empirical study. The relationships among biodiversity dimensions is not well understood, nor how differences among dimensions could influence conservation decision making. Using the avian community as a study system, we explored the relationships of breadth metrics from the taxonomic, phylogenetic, and functional dimensions among each other and across …

The Biological Significance And Utility Of Feeding By Dermestes Maculatus, Braymond Adams

School of Natural Resources: Dissertations, Theses, and Student Research

With their efficient feeding habits and tolerance to very low moisture and humidity, beetles in the Family Dermestidae are especially adapted to variable environments and habitats. Dermestid cultures have been in use since 1922 in cleaning tissue and flesh from bones, and proven benefit in multiple fields, including zoology, ornithology, and forensics. Dermestid feeding behaviors when coupled with known life stage and insect succession information aids in providing significant entomological evidence. However, the feeding activities of insects, like those of vertebrate scavengers and predators, change remains and may leave artifacts that can be sometimes be difficult to assign to a …

Notes: Two-Headed White-Tailed Deer Fetus, William F. Jensen, Daniel M. Grove, Ryan J. Herigstad, William J. Haase

The Prairie Naturalist

On 6 April 2018 a female white-tailed deer (Odocoileus virginianus dakotensis) was hit and killed by a vehicle along HWY 1806 in rural Morton County, North Dakota, USA (N46o 38.617; W100o 42.901). Based upon dental eruption and wear (Severinghaus 1949), the female was estimated to be a >4.5 years-of-age. A male fetus with parapagus diprosopus (i.e., shared face) apparently was expelled from the adult female, and a domestic canine (Canis lupus familiaris) carried the fetus to a private residence. The resident contacted the North Dakota Game and Fish Department (NDGFD) to turn in the fetus. On 10 April 2018, NDGFD …

Review: Canids Of The World: Wolves, Wild Dogs, Foxes, Jackals, Coyotes, And Their Relatives. José R. Castelló., Jonathan (Jon) Way

The Prairie Naturalist

Canids of the World is one of those reads where just when you think that something cannot be beat, this book comes out. What I mean by that is that I have read many works on wolves and other canids, most recently Nate Blakeslee’s American Wolf (Way 2017), and I have enjoyed and been enthralled with many of them. But Canids of the World may take the cake for being the most impressive book available on canids. For a modest price of just under $30.00, you can own a book that has over 600 amazing high-resolution glossy photographs of every …

Edges And Rushes Of Minnesota: The Completeguidetospeciesidentification. Welby R. Smith; Photography By Richard Haug., Edward S. Dekeyser

The Prairie Naturalist

Even the most seasoned individual with a plant identification background can relate to the difficulty of identifying sedges and rushes to the species level. Historically, one has had to rely on dichotomous keys to identify a sedge or rush species in the field. After hours of frustration, a person ends up collecting the plant and, if lucky, bringing the collection back to a herbarium where it can be compared to known specimens. I have been collecting and identifying sedge and rush species for over 25 years, and author Welby Smith along with photographer Richard Haug have published what I believe …

Review: Behavior Of The Golden Eagle: An Illustrated Ethogram. David H. Ellis (Illustrated By N. John Schmitt)., Jeremy E. Guinn

The Prairie Naturalist

Author David H. Ellis and illustrator N. John Schmitt deliver precisely what is promised in Behavior of the Golden Eagle: An Illustrated Ethogram. This “little volume,” as the author coins it, represents a single source for defining, identifying, and describing behaviors of the Golden Eagle (Aquila chrysaetos). With the inclusion of Schmitt’s exceptional drawings, the book is a piece of art, as well as the most useful manual describing Golden Eagle behaviors. Nearly four decades earlier, Ellis (1979) authored the very first Golden Eagle ethogram—the set of repeated standard behaviors for a species called action patterns—and in his new book, …

Metabolic Gas Emissions From Prairie Soil Containing Foraging Termites, Charles E. Konemann, B.M. Kard, Tom A. Royer, Mark E. Payton

The Prairie Naturalist

Differences in subterranean termite metabolic gas emissions are readily observed in laboratory experiments. However, in natural field ecosystems a primary difficulty in measuring subterranean termite gases is non-homogeneous distribution of foraging termites in soil. Our field experiment was designed to aggregate foragers of the 'eastern subterranean termite', Reticulitermes flavipes Kollar (EST), in one of four flux chamber configurations placed on a tallgrass prairie throughout 2014 and 2015. We used differently configured flux chambers to measure metabolic gas emissions from soil with or without foraging termites on The Joseph H. Williams Tallgrass Prairie Preserve (TGPP) in north-central Oklahoma. Foraging termitesaggregated in …

Review: North American Ducks, Geese & Swans: Identification Guide. Frank S. Todd., Kevin M. Ringelman

The Prairie Naturalist

The North American Duck, Geese & Swans: Identification Guide, released in 2018, is the culmination of a lifetime of waterfowl photography by the late Frank Todd. Indeed, this book stands apart from other identification guides as being entirely photo-driven, with minimal introductory material, notations of field marks, or descriptions of the various waterfowl species. It is small enough to be carried in the field (6.5” × 9” × 0.5”), but most readers will find it less useful than a standard bird identification book (Sibley 2014), even for waterfowl. As the title suggests, the Todd guide focuses on North American species, …

New Breeding Record And Location For Wilson’S Phalarope (Phalaropus Tricolor) In The Nebraska Great Plains, Usa, Madison O. Sutton, Nico Arcilla

The Prairie Naturalist

Wilson’s phalarope (Phalaropus tricolor; Scolopacidae) is a migratory shorebird that relies on interior wetlands for foraging and breeding (Colwell and Jehl 1994, van Gils et al. 2018). Its global population status is unclear (Colwell and Jehl 1994, Lesterhuis and Clay 2010), and is variously listed as declining (Morrison et al. 2006, van Gils et al. 2018), increasing (Andres 2009, BirdLife International 2018), and exhibiting a long-term decline but recent stability (Sauer et al. 2011, Andres et al. 2012). Its global population estimate of 1.5 million birds has not been updated for 30 years, since 1988 (Colwell and Jehl 1994, Lesterhuis …

Comparison Of Northern Flying And Red Squirrel Phylogenies With Focus On The Insular United States, Alyssa M. Kiesow, Hugh B. Britten

The Prairie Naturalist

Northern flying squirrel (Glaucomys sabrinus) and red squirrel (Tamiasciurus hudsonicus) populations are endemic to northern North America, including the Black Hills. The Black Hills populations are considered disjunct from other populations within their range. We examined insular populations to determine whether arboreal squirrels in the Black Hills each represent a unique population. We trapped and collected ear samples from northern flying and red squirrels in the Black Hills and in areas of Montana, Wyoming, Idaho, Utah, Minnesota, and Wisconsin to infer population phylogenies with special consideration of the Black Hills population. Microsatellite loci and two mtDNA sequences were used for …

Preparing An Effective Poster Presentation, Christopher N. Jacques

The Prairie Naturalist

Greetings GPNSS members! By the time you read this editorial, many of have been experiencing the fury unleashed by ‘Old Man Winter’ and may find yourself counting the days until warmer spring temperatures return once again to the Great Plains. Until then, just a couple more months of bitter cold temperatures, strong winds, and blowing and drifting snow. But not to worry, winter also provides the cold weather enthusiasts among us a chance to enjoy a range of outdoor recreational opportunities, a chance to reflect on the previous year in review, exciting professional and personal opportunities ushered in by the …

Red-Bellied Snake (Storeria Occipitomaculata) Copulation In South Dakota, Drew R. Davis

The Prairie Naturalist

Storeria occipitomaculata is a small, terrestrial species of snake that occurs across much of eastern North America (Ernst and Barbour 1989, Ernst 2002, Ernst and Ernst 2003). Due to this widespread distribution, S. occipitomaculata faces varied climates that likely result in regional differences in reproductive phenology. Much of what is known about the reproductive ecology of S. occipitomaculata has been documented from the southeastern portion of its range in North America (South Carolina: Semlitsch and Moran 1984, North Carolina: Willson and Dorcas 2004), though Blanchard (1937) studied a population from northern Michigan. The exact reproductive timing in this species has …

Modeling The Response Of Black Walnut -Dominant Mixed Hardwoods To Seasonal Climate Effects With Uav-Based Hyperspectral Sensor And Aerial Photogrammetry, Tyler G. Bradford

MSU Graduate Theses

The development of compact sensors in recent years has inspired the use of UAS-based hyperspectral and aerial imaging techniques for small-scale remote sensing applications. With increasing concerns about climate change, spectrally-derived vegetation indices (VIs) have proven useful for quantifying stress-induced vegetation response. The goal of this study was to develop predictive models and assess methodology for modeling the biological response of a black walnut -dominant mixed hardwood stand to seasonal climate events using UAV-based hyperspectral remote-sensing. The derived VIs were evaluated against the means of four seasonal measures of climate calculated for a two-week period prior to the flight date. …

Ncer Assistance Agreement Annual Progress Report For Grant #83582401 - Assessment Of Stormwater Harvesting Via Manage Aquifer Recharge (Mar) To Develop New Water Supplies In The Arid West: The Salt Lake Valley Example, Ryan Dupont, Joan E. Mclean, Richard C. Peralta, Sarah E. Null, Douglas B. Jackson-Smith

Civil and Environmental Engineering Faculty Publications

The goals of the original proposed project remain the same, that is, to test the hypothesis that Managed Aquifer Recharge (MAR) for stormwater harvesting is a technically feasible, socially and environmentally acceptable, economically viable, and legally feasible option for developing new water supplies for arid Western urban ecosystems experiencing increasing population, and climate change pressures on existing water resources. The project is being carried out via three distinct but integrated components that include: 1) Monitoring of existing distributed MAR harvesting schemes involving a growing number of demonstration Green Infrastructure (GI) test sites; 2) Integrated stormwater/vadose zone/groundwater/ ecosystem services modeling; and …

Constructing A Data-Based Mortality Profile For Avian Tower Kills At Telecommunication Towers In Illinois, Rachel Dipietro

Theses and Dissertations

During spring and fall seasons, Neotropical migratory passerines travel nocturnally across the Western Hemisphere between their wintering and breeding grounds, often encountering man-made threats. One hazard that has gained considerable publicity in recent decades is the communication tower. While there have been many tower kill studies recorded, there has been no attempt at predicting the risk of towers based on their different attributes (e.g., height, type of light, landscape placement) spatially on a regional scale. The objective of this study was to create seasonal mortality profile maps in GIS for Illinois, based on tower attributes combined with key factors such …

Examining Patterns In Nest Predation Using Artificial Nests, Victoria L. Simonsen

School of Natural Resources: Dissertations, Theses, and Student Research

The use of artificial nests to study the predation of avian nests has faced disregard by ecologists due to inconsistencies found between the survival rates of real and artificial nests across studies and reviews. The negative perception of artificial nests providing an inconsistent assessment of survival has thus fostered the perception that artificial nests are a secondary option to be used to overcome logistical hurdles associated with achieving sufficient sample sizes in systems where study species are rare or elusive, or as merely a preliminary method to study predation across gradients. We argue that the greatest mistake ecologists have made …

Ground-Truthing Social Vulnerability Indices Of Alaska Fishing Communities, Anna Lavoie, Kim Sparks, Stephen Kasperski, Amber Himes-Cornell, Kristin Hoelting, Conor Maguire

All Faculty Scholarship for the College of the Sciences

Community vulnerability is increasingly evaluated through quantitative social indices, typically developed using secondary data sources rather than primary data collection. It is necessary to understand the validity of these indices if they will be used to inform policy and decision making. This paper presents a ground-truthing effort to validate quantitative indices that characterize the well-being of Alaska fishing communities. We utilized ethnographic data collected from 13 representative communities and a capital assets framework to ground-truth the indices, in which qualitative ranks of vulnerability were compared against quantitative indices. The majority (73.8%) of ranks were in complete or moderate agreement and …

Plants, Parasites, And Pollinators: The Effects Of Medicinal Pollens On A Common Gut Parasite In Bumble Bees, George Locascio

Masters Theses

Declines in several pollinator species are due to a variety of factors, including pathogens. Incorporating pollinator-friendly plant species into wild and agricultural habitats could reduce the stress of pathogens if food sources act medicinally against pathogens. Previous research demonstrated one domesticated sunflower cultivar (Helianthus annuus) can dramatically reduce a gut pathogen (Crithidia bombi) of the common eastern bumble bee, Bombus impatiens. To ascertain the breadth of this medicinal trait, we tested whether pollen from several H. annuus cultivars and four relatives could also reduce C. bombi infections in B. impatiens. We also investigated whether …

Integrating Multiple Genetic Detection Methods To Estimate Population Density Of Social And Territorial Carnivores, Sean M. Murphy, Ben C. Augustine, Jennifer R. Adams, Lisette P. Waits, John J. Cox

Forestry and Natural Resources Faculty Publications

Spatial capture–recapture models can produce unbiased estimates of population density, but sparse detection data often plague studies of social and territorial carnivores. Integrating multiple types of detection data can improve estimation of the spatial scale parameter (σ), activity center locations, and density. Noninvasive genetic sampling is effective for detecting carnivores, but social structure and territoriality could cause differential detectability among population cohorts for different detection methods. Using three observation models, we evaluated the integration of genetic detection data from noninvasive hair and scat sampling of the social and territorial coyote (Canis latrans). Although precision of estimated density was …

Impacts Of Climate Change And Bioenergy Markets On The Profitability Of Slash Pine Pulpwood Production In The Southeastern United States, Andrea Susaeta, Pankaj Lal

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

In this study, we assessed the impacts of climate change on the production of pulpwood and biomass for bioenergy, and the profitability of slash pine stands in the Southeastern United States. We employed the 3-PG (Physiological Processes Predicting Growth) model to determine the effects of future climates on forest growth and integrated it with a stand-level economic model to determine their impacts on optimal forest management. We found that the average production of pulpwood increased for all sites by 7.5 m³ ha⁻¹ for all climatic scenarios and productivity conditions. In the case of forest biomass for bioenergy, the …
