The Effects Of Woody Vegetation Encroachment And Removal Within A Coastal Fen, Joseph Saler

Cal Poly Humboldt theses and projects

Early successional wetland habitat is being lost in temperate regions worldwide as a result of changes in disturbance regimes that allow for the establishment and dominance of woody species. In particular, this phenomenon is pronounced in fens, which harbor high numbers of rare herbaceous species that require early successional habitat. I investigated the relationship between woody vegetation encroachment and herbaceous species diversity within a Northern California coastal fen that has been undergoing encroachment by woody vegetation for ca. 80 years by recording species richness and cover data from 338 permanent plots throughout the fen. I also investigated the effect of …

Small Mammal Communities In Grasslands At The Grand Forks Air Force Base, North Dakota, Usa, Lynda R. Lafond, Elizabeth H. Rave, Kathryn A. Yurkonis

The Prairie Naturalist

Small mammals are important in grasslands but are often overlooked in management and reconstruction efforts. We sampled small mammals in three sites on the Grand Forks Air Force Base (GFAFB) located in central Grand Forks County, North Dakota, USA. The study sites varied in their management history and represented the three major types of grasslands (reconstructed prairie, old field, and hay field) within Grand Forks County. We captured 463 individuals of six species with Sherman live traps in summer (June, July, August) 2014 and 2015. We captured the most individuals and species (295 individuals of 5 species), including all shrews …

Captive Ring-Necked Pheasant Response To Very High Experimental Doses Of Lead, Travis J. Runia, Alex J. Solem

The Prairie Naturalist

Ingestion of spent lead pellets is a well-documented source of lead exposure in free-ranging birds, although the consequence of lead ingestion varies widely among avian guilds. Ring-necked pheasants (Phasianus colchicus) appear to be less susceptible to lead poisoning than other game birds. Our objectives were to determine survival, liver lead accumulation, and body mass change of 129 captive-raised pheasants in response to being gavage-fed 5, 10, 20, or 40 lead pellets. All pheasants survived the 21-day experiment. Liver-lead levels were positively correlated with the number of lead pellets retained and negatively correlated with beginning body mass. Change in percent body …

Recent Observations Of Water Shrews In Northeastern South Dakota, Dennis Skadsen, Robert M. Timm

The Prairie Naturalist

North American water shrews in the genus Sorex are a complex of at least five species, three of which were recognized historically, Sorex alasksans, S. bendirii, and S. palustris (Hall 1981). Within what was previously considered the single, widespread northern species, S. palustris, two additional species are now recognized, S. albibarbis in the eastern US and Canada and S. navigator in the western United States and Canada (Hope et al. 2014; Nagorsen et al. 2017; Woodman 2018). The American water shrew (Sorex palustris) originally was documented in South Dakota by three females, two were collected 1876 and …

Review Of Sky Dance Of The Woodcock: The Habits And Habitats Of A Strange Little Bird, By Greg Hoch, David E. Andersen

The Prairie Naturalist

American Woodcock (Scolopax minor) have enthralled conservationists (including Aldo Leopold), bird watchers, wildlife enthusiasts, hunters, and others interested in the natural world for centuries. No doubt, woodcock also have enthralled humans in North America for millennia prior to written descriptions of the woodcock’s courtship displays, habitat preferences, and curious behavior and anatomy. As perhaps the most extensively studied species of shorebird in the world, there is a rich and extensive literature, both scientific and popular, focused on woodcock ecology, behavior, and hunting. To that extensive body of literature, Sky Dance of the Woodcock provides an updated summary of …

Factors Limiting Reintroduced Plains Topminnow, Fundulus Sciadicus, Populations In Central Great Plains Streams, Joseph Thiessen, Keith D. Koupal, Casey W. Schoenebeck

The Prairie Naturalist

The plains topminnow (Fundulus sciadicus) is an endemic Great Plains stream fish that has experienced declines in geographic range and local abundance. Due to these declines, the species has been considered for federal protection and designated with conservation status in states throughout its historic range. The reasons for declines are likely similar to hypothesized factors for other endemic stream fish declines in the Great Plains. To investigate potential limiting factors a suite of 17 historic sites with reintroduced plains topminnow populations across Nebraska were evaluated for current populations and if plains topminnow were absent, additional fish were introduced. …

Bats Of The Loess Hills Ecoregion Of Southeast Nebraska, Virgil Brack Jr, Dale W. Sparks, Darwin C. Brack

The Prairie Naturalist

We surveyed bats at 49 sites in the Loess Hills Ecoregion of southeastern Nebraska, along the western edge of the eastern forest biome in eastern Richardson, Nemaha, and Otoe counties. We completed this study shortly before the northern long-eared bat (Myotis septentrionalis) was listed by the United States Fish and Wildlife Service under the Endangered Species Act. The expectation of listing, along with potential presence of the endangered Indiana bat (Myotis sodalis), motivated the study. We captured 183 bats of five species: eastern red bat (Lasiurus borealis) (n = 103; 56 %), big brown …

Serological Survey And Pathogen Exposure Of Adult Female White-Tailed Deer In The Western Dakotas, Katherine L. Moratz, Bailey S. Gullikson, Eric S. Michel, Daniel M. Grove, Jonathan A. Jenks, William Jensen

The Prairie Naturalist

Establishing baseline values for pathogen exposure and nutritional indices is necessary to monitor population health. However, little is known about white-tailed deer (Odocoileus virginianus) pathogen exposure and nutritional condition in the Northern Great Plains. Our objective was to assess pathogen exposure and establish nutritional indices for female white-tailed deer in Dunn and Grant counties, North Dakota and Perkins County, South Dakota. During 2014, we collected blood serum from 150 adult female white-tailed deer. Pathogens with the highest antibody prevalence included West Nile Virus (WNV; 85%), epizootic hemorrhagic disease (48%), and malignant catarrhal fever (32%). Serum values for creatine …

Review Of Grasslands And Climate Change By David J. Gibson And Jonathan A. Newman, Neal D. Noemuth

The Prairie Naturalist

The last decade has seen an explosion of information about climate change, some of which is contradictory, much of which is confusing, and the entirety of which is too much for the typical biologist or scientist to assemble and comprehend. This is why reviews such as Grasslands and Climate Change, edited by David Gibson and Jonathan Newman, are so valuable. To produce this review of climate change issues and influences relative to grasslands, Gibson and Newman recruited 30 scientists—predominantly from Europe and North America—who wrote 19 chapters dealing with various aspects of grasslands and climate change. The chapters are grouped …

Biologists who live in the Great Plains of North America know well the general aspersion cast toward our regional home by those unfamiliar with the region and its natural treasures. Larkin Powell alludes to this all-too-common aspersion and diplomatically dispels it in his ornithological showcase of the Great Plains, simply titled Great Plains Birds. The book is a nice, quick read and a well-composed profile of the region’s avian biogeographical history, its disruptions, conservation remedies, examples of basic bird biology, and tips on how to enjoy the bird life on display in this dynamic region. Having been an ornithologist …

Review Of A Field Guide To The Natural World Of The Twin Cities By John J. Moriarty, Photography By Siah L. St. Clair, Douglas H. Johnson, Bonnie Sample

The Prairie Naturalist

A Field Guide to the Natural World of the Twin Cities has two foci: natural areas in the Twin Cities of Minnesota and the species that live in each. The geographical scope is the seven counties that envelop Minneapolis and Saint Paul. The author describes nine major habitat types that can be found there: prairie, savanna, big woods, oak woods, wetlands (marshes and swamps), fens and bogs, lakes, rivers, and urban and suburban. It is useful to know that “big woods” are not just woods that are large in extent, but woodlands that occur in Minnesota and western Wisconsin dominated …

Factors Affecting White Bass Abundance In Two Missouri River Reservoirs, William J. Radigan, Mark J. Fincel

The Prairie Naturalist

Annual angler harvest of white bass (Morone chrysops) increased from 1985–2005 in Lake Oahe and Lake Sharpe, two mainstem Missouri River reservoirs in South Dakota. In 2006, harvest rates dropped appreciably in both reservoirs and remained low through 2015. It is hypothesized that a confirmed 2005 columnaris disease outbreak led to reduced annual angler harvest of white bass from both reservoirs. Mean annual angler harvest prior to the outbreak (1985–2005) in Lake Oahe decreased 65% and in Lake Sharpe decreased 57% post outbreak (2006–2015). To assess potential causes of sustained decreased adult white bass abundance in the reservoirs, …

Suitability Of Single-Pass Backpack Electrofishing To Estimate Fish Abundance And Describe Assemblage Structure In Prairie Streams, Morgan J. Kauth, David A. Schumann, Katie N.B. Graeb, William Wyatt Hoback

The Prairie Naturalist

Electrofishing is commonly used by fisheries professionals to assess fish assemblage structure and species abundance in streams. Accurate estimates of fish abundance and, consequently assemblage metrics, are typically generated with mark-recapture or maximum-likelihood depletion techniques, but doing so requires considerable sampling effort. Less intensive sampling approaches may be beneficial to fisheries managers, particularly in cases where frequent sampling of many streams is preferred. We used regression and Spearman rank-order correlation analyses to compare species catch rates and the assemblage metrics generated from single-pass electrofishing samples with multiple-pass depletion abundance estimates in Nebraska streams. We examined the influence of instream habitat …

Incidental Captures Of Plains Spotted Skunks In Central South Dakota, Samantha Fino, Joshua D. Stafford, Aaron T. Pearse, Jonathan A. Jenks

The Prairie Naturalist

The plains spotted skunk (Spilogale putorius interrupta) had a historically broad distribution in the central United States, extending from the Mississippi River west to the Rocky Mountains. This subspecies of the eastern spotted skunk (S. putorius) has experienced population declines in recent decades possibly due to habitat loss and reduction of prey through conversion of grasslands and forests to croplands, as well as reductions in abandoned buildings, fence rows, creek bottoms, and wood piles throughout the region (Crabb 1948, Kaplan and Mead 1991, Gompper and Hackett 2005, Sasse 2017). Woody debris provides access to prey, and …

Channel Catfish Reproductive Traits In The Lower Platte River, Nebraska, Usa, Mackenzie Zwiener, Jonathan J. Spurgeon, Mark Pegg

The Prairie Naturalist

Reproductive traits including fecundity, egg diameter, and condition of freshwater fishes influence offspring survival and abundance and may provide insight regarding timing of reproduction (Winemiller and Rose 1992, Johnston and Leggett 2002). Fish size (i.e., length or weight) may influence the number of eggs produced by an individual female (i.e., fecundity; Michaletz 1998). Larger individuals may, thus, disproportionately contribute to year-classes through increased fecundity if egg and larval survival is similar or greater than those from smaller reproductive females (Gwinn et al. 2015). Likewise, maternal fish size may influence egg diameter and offspring survival, whereby larger egg diameters are associated …

Review Of Gulls Simplified: A Comparative Approach To Identification By Pete Dunne And Kevin T. Karlson, Garrett J. Macdonald

The Prairie Naturalist

The title of Pete Dunne and Kevin Karlson’s new book, Gulls Simplified, may seem like an oxymoron to many birders. Gulls are, after all, one of the most vexing groups of North American birds due to their myriad identification challenges, and many seasoned birders simply “don’t do gulls.” Indeed, Dunne, in the first line of the Introduction (page 13), writes, “Ask any bird-watcher to name the bird group that is most intimidating, and to a man, woman, and tour leader they often shout: GULLS!” The genesis of the book, and the authors’ approach to identification within, arises from the notion …

Review Of Birds Of Prey Of The West: A Field Guide, By Brian K. Wheeler, Daniel Casey

The Prairie Naturalist

Birds of prey epitomize much of what attracts us to birding. Many are large and easy to observe, particularly in open landscapes. Their predatory nature and behavior give them an added aura of wildness; their migrations can be spectacular. And even veteran birders should enjoy the challenge of identifying the myriad of plumage variations shown by different ages, sexes, subspecies, and color morphs. With his newest effort, Birds of Prey of the West, Brian Wheeler has compiled a comprehensive and enhanced field guide with illustrations that stunningly capture that variation, combined with enough additional context to make it a valuable …

Island Invasion: The Silent Crisis In Hawaii, Sophia Janssen

Pomona Senior Theses

Keeping out invasive species may, upon first review, seem like a trivial environmental cry from ecologists and deep environmentalists; a belated wish to return to an undeveloped world where nature was pristine. However invasive species create problems that impact all of us and can have far more severe consequences than changing a stunning landscape. These problems are heightened in islands like Hawaii, where the fragile ecosystems have developed over centuries of evolution and adaptation. The introduction of a disease-carrying mosquito can put the people of Hawaii at risk to many vector-born illnesses and create an epidemic, taking human life. The …

Quantifying Signpost Usage By Captive Male White-Tailed Deer, Cassie L. Auxt, Eric S. Michel, Jonathan A. Jenks

The Prairie Naturalist

White-tailed deer (Odocoileus virginianus) use rubbing of signpost structures to communicate during the breeding season. Rubbing of signpost structures allows deer to communicate via visual and chemical cues, which allows them to establish dominance hierarchies and maintain hierarchal status throughout the breeding season (Moore and Marchinton 1974, Miller et al. 1981, Hewitt 2011). Once a living tree is rubbed, the exposed light-colored sapwood creates a stark contrast in wooded areas, increasing visibility and further enticing deer to investigate the structure (Oehler et al. 1995). Anatomically, the tubular apocrine sudoriferous glands of white-tailed deer are located at the antler …

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 …

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 …

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

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 …
