Energy Sprawl Solutions, Nicola Koper
Energy Sprawl Solutions, Nicola Koper
The Prairie Naturalist
Energy sprawl affects all the major conservation issues of our age, from habitat loss and fragmentation to anthropogenic noise and climate change. As such, minimizing and solving its associated problems should be a key focus for conservation biologists. Kiesecker and Naugle provide an impressive and compact book that focusses on solving environmental and social problems likely to result from a transition from non- renewable to far less efficient renewable energy sources.
Energy Sprawl Solutions summarizes numerous relevant peer-reviewed academic papers, and outlines management and planning implications of each one, ultimately resolving these into fairly clear prescriptive recommendations for moving forward. …
Unique Nesting Behavior By Trumpeter Swans (Cygnus Buccinator), Heather M. Johnson, Michael Forsberg, Letitia Reichart, Mark P. Vrtiska
Unique Nesting Behavior By Trumpeter Swans (Cygnus Buccinator), Heather M. Johnson, Michael Forsberg, Letitia Reichart, Mark P. Vrtiska
The Prairie Naturalist
Nesting behavior by Trumpeter swans (Cygnus buccinator) has been well documented for most populations. Both sexes cooperate in nest construction, which takes 11–35 days to complete (Hansen et al. 1971, Cooper 1979). Nests generally range from 1.5–3.6 meters in diameter and 1.5 meters in height and are typically built on solid structures such as a muskrat (Ondatra zibethicus) house or an island (Hansen et al. 1971, Cooper 1979). However, we discovered an atypical Trumpeter swan nest built of cattail (Typha angustifolia L.) located on Vaughn Lake, in Cherry County, Nebraska on 13 May 2016.
We monitored the atypical nest by …
The Considerations Given To Determining Authorship, Christopher N. Jacques
The Considerations Given To Determining Authorship, Christopher N. Jacques
The Prairie Naturalist
Greetings GPNSS members! Over the past year, I have been asked by prospective authors and colleagues whether The Prairie Naturalist has criteria for authorship. Given that this issue continues to arise, it is comforting to know that I am not the only one who struggles with considerations given to determining authorship. I checked the current submission guidelines and found nothing specific, which in turn motivated me to explore what other journals such as the Journal of Wildlife Management, Proceedings of the National Academy of Sciences, and Ecology recommend to prospective authors (Merrill 2015). Much to my surprise, discussions of authorship …
One More Warbler: A Life With Birds., Laura Erickson
One More Warbler: A Life With Birds., Laura Erickson
The Prairie Naturalist
Imagine going on a Victor Emanuel Nature Tour, seated in the van next to Victor Emanuel himself. Between birding stops, this man who has seen over 6,000 species as a world-renowned conservationist and innovator in ecotourism regales you with stories. He starts with his “spark bird”: when he was eight years old, he was taken with the beauty of a pair of Northern Cardinals (Cardinalis cardinalis), and was hooked. Whenever people pile back into the van after a birding stop, he starts another story.
That’s how One More Warbler: A Life with Birds reads, as if Emanuel sat down with …
Field Discrimination Of Prairie Deer Mice And White-Footed Mice Using Morphological Characteristics, Jacob L. Berl, Kelton M. Verble, Elizabeth A. Flaherty, Robert K.S. Swihart
Field Discrimination Of Prairie Deer Mice And White-Footed Mice Using Morphological Characteristics, Jacob L. Berl, Kelton M. Verble, Elizabeth A. Flaherty, Robert K.S. Swihart
The Prairie Naturalist
Field discrimination of prairie deer mice (Peromyscus maniculatus bairdii) and white-footed mice (P. leucopus noveboracensis) can be difficult throughout much of the central United States where they co-occur. We live-trapped prairie deer mice and white-footed mice within forested and row-crop habitats in central Indiana and used multiplex PCR with species-specific primers to positively determine species identification. We collected a suite of commonly measured external morphological traits (body weight and lengths of ear, hindfoot, tail, and body) from each captured animal. Individuals were assigned to species based on analysis of DNA; discriminant function analysis was used to …
Weed Establishment And Persistence After Water Pipeline Installation And Reclamation In The Mixed Grass Prairie Of Western North Dakota, Erin K. Espeland, Lora B. Perkins
Weed Establishment And Persistence After Water Pipeline Installation And Reclamation In The Mixed Grass Prairie Of Western North Dakota, Erin K. Espeland, Lora B. Perkins
Natural Resource Management Faculty Publications
Weeds in reclamations interfere with success by: 1) competing with desirable species seeded during revegetation; 2) preventing recolonization of reclamations by native species; and 3) reducing the integrity of landscapes by expanding from reclamations into adjacent, intact areas. In the Bakken oilfield of western North Dakota, dispersed reclamation activity and increased traffic may provide many opportunities for weeds to spread. To determine the potential for disturbance and reclamation to increase resident weed populations and introduce new weed species, we tracked twenty-one weed (non-native/ruderal/invasive) species over a four-year period after the installation of a 1.8 km livestock water pipeline and subsequent …
Notes: Range Extension Of The Virginia Opossum (Didelphis Virginiana) In North Dakota, Lisa L. Walsh, Robert Seabloom, Cody W. Thompson
Notes: Range Extension Of The Virginia Opossum (Didelphis Virginiana) In North Dakota, Lisa L. Walsh, Robert Seabloom, Cody W. Thompson
The Prairie Naturalist
The Virginia opossum (Didelphis virginiana) is broadly distributed across North America from Costa Rica in the south to southern Ontario in the north and from the southern Great Plains in the west to the eastern United States. The Virginia opossum also was introduced multiple times to thePacific Coast beginning in the late 1800s and has established populations in that region. This species is a habitat generalist known to frequent wetland and hardwood habitats but also can be found in grasslands, along forest edges, and in agricultural and suburban settings throughout its range. However, the Virginia opossum is adapted …

Book Reviews: Raptors Of Mexico And Central America. William S. Clark And N. John Schmitt., Jack Jack Eitniear
The Prairie Naturalist
Whether a raptor is cryptically perched in the shadows or is viewed only as a silhouette soaring in the clouds below the glaring midday sun, raptor identification can be challenging. If you are observing raptors in the North Temperate Zone, several guides (e.g., Clark and Wheeler 2001 Dunne et al.2012) will aid you with such identifications, but few resources exist for visitors south of this zone. So, if you are interested in identifying the 69 species of diurnal raptors found in Mexico and Central America, the recently released Raptors of Mexico and Central America by William S. Clark and N. …

Prairie Falcon Depredation Attempts On A Greater Prairie-Chicken Lek In South-Central Nebraska, Andrew J. Caven, Joshua D. Wiese, William R. Wallauer
Prairie Falcon Depredation Attempts On A Greater Prairie-Chicken Lek In South-Central Nebraska, Andrew J. Caven, Joshua D. Wiese, William R. Wallauer
The Prairie Naturalist
Little information exists concerning Prairie falcons’ (Falco mexicanus; PRFA) seasonal movements, habitat use, and diet outside of the breeding season; this is especially true in the eastern portion of its wintering and migratory range (Steenhof 1998, Sharpe et al. 2001, Steenhof et al. 2005). Prairie falcons prey on ground squirrels (Spermophilus spp.), prairie dogs (Cynomys spp.), wood rats (Neotoma spp.), and other rodents during the breeding season (Bond 1936, 1942, MacLaren et al. 1988, Steenhof 1998, Steenhof et al. 1999, Johnsgard 2013). They utilize avian prey regionally as well, including western meadowlarks (Sturnella neglecta …
Evaluation Of Very-Long-Chain Fatty Acid-Inhibiting Herbicides In Arkansas Rice Production, John Ansley Godwin
Evaluation Of Very-Long-Chain Fatty Acid-Inhibiting Herbicides In Arkansas Rice Production, John Ansley Godwin
Graduate Theses and Dissertations
Because of the evolution of herbicide-resistant weeds, such as barnyardgrass and red rice in rice, there is a need for alternative herbicide sites of action. Very-long-chain fatty acid (VLCFA)-inhibiting herbicides are not labeled for use in U.S. rice production; however, this site of action (SOA) has been used with success in Asian rice. The VLCFA-inhibiting herbicides pethoxamid, pyroxasulfone, acetochlor, and S-metolachlor were evaluated for rice tolerance and control of commonly problematic weeds in Arkansas rice at various rates and application timings. Pyroxasulfone and S-metolachlor were deemed unfit for use in rice production because of negative effects on rice visual injury, …
Characterization Of Multiple-Herbicide-Resistant Echinochloa Colona From Arkansas, Christopher Edward Rouse
Characterization Of Multiple-Herbicide-Resistant Echinochloa Colona From Arkansas, Christopher Edward Rouse
Graduate Theses and Dissertations
Echinochloa species are highly adaptive weeds that have the potential to impact crops in a variety of environments. This has positioned them as the most problematic weeds in a number of USA cropping systems with some species having the distinction of the 'worst herbicide-resistant weeds' in the world. Recent evidence has positioned Echinochloa colona (junglerice) as the most dominant in Arkansas and throughout the Mid-South, USA, especially in rice (Oryza sativa L.) and soybean (Glycine max L.) production fields. A history of extensive herbicide-use for management and a lack of integrated or diverse approaches to management have led to rampant …
Characterization Of Glyphosate-Resistant Amaranthus Palmeri (Palmer Amaranth) Tolerance To Als- And Hppd-Inhibiting Herbicides, Shilpa Singh
Characterization Of Glyphosate-Resistant Amaranthus Palmeri (Palmer Amaranth) Tolerance To Als- And Hppd-Inhibiting Herbicides, Shilpa Singh
Graduate Theses and Dissertations
Palmer amaranth is a principal weed problem across the United States and is resistant to several herbicide modes of action. By 2008, Palmer amaranth in Arkansas was reported to be resistant to both ALS- and EPSPS-inhibitors, but the predominant resistance mechanisms are yet to be explored. Herbicide options with different modes of action are needed to provide effective Palmer amaranth control and HPPD-inhibitors (e.g. mesotrione) are among these. The goal of this research was to elucidate the resistance profile of Palmer amaranth in Arkansas to ALS herbicides and glyphosate (EPSPS-inhibitor) as well as evaluate the differential tolerance of Palmer amaranth …
Giant Salvinia, Salvinia Molesta (Salviniaceae): Evaluation Of Sub-Optimum Temperatures On Survival Of The Giant Salvinia Weevil, Cyrtobagous Salviniae (Coleoptera: Curculionidae) And Integration Of Management Practices With Aquatic Herbicides, Lauren W. Cozad
LSU Master's Theses
Salvinia molesta is one of the world’s worst aquatic weeds and has cost Louisiana nearly $7 million worth of damage and economic impact each year. While aquatic herbicides and the biological control agent, Cyrtobagous salviniae, are the most efficacious control methods, there are limitations with each technology. Therefore, studies were conducted to evaluate insect mortality at upper and lower lethal temperatures and investigate integrated pest management (IPM) with insects and herbicides. Three Louisiana populations of C. salviniae were tested to evaluate cold tolerance and found that at 0°C, the Bayou Nicholas population was 1.3- and 1.4-times more cold tolerant …
Shift In Icelandic Plant Populations Due To Climate Change: Through The Lens Of Natural Dyes, Molly Pluenneke
Shift In Icelandic Plant Populations Due To Climate Change: Through The Lens Of Natural Dyes, Molly Pluenneke
Independent Study Project (ISP) Collection
Northern residing plant species are at the highest risk for extinction due to temperature rise related to climate change (Schöb, Manuel, Choler & Veit, 2009). Climate change has also led to a northern shift in the geographic distribution of plant species (Parmesan & Yohe, 2003). This could lead to a necessary alteration in the way natural resources are utilized in arctic countries like Iceland (Lim-Camacho et al, 2017). The purpose of this study is to analyze the way in which Icelandic plant species used in natural dye practices may shift in distribution due to climate change and the potential impact …

Managing Opuntioid Cacti In Australia - Best Practice Control Manual For Austrocylindropuntia, Cylindropuntia And Optunia Species, M. R. Sheehan, S. Potter
Biosecurity published reports
The twenty-seven species of opuntioid cacti that are recognised as Weeds of National Significance are some of Australia's worst weeds. They grow over a wide climatic range and have impacted on pastoral and agricultural use of large tracts of land; pose an environmental risk to wildlife; and reduce aesthetic and recreational use, with direct impact on human safety.
Weedy infestations occur in all states and territories. Some are extensive, covering hundreds of thousands of hectares with a significant potential for range expansion
Over time there has been a substantial effort by government, industry, landholders and community groups to manage opuntioid …
Survey Of Invasive Lantana Camara At Makirovana-Tsihomanaomby Forest Complex, Eliza Pessereau
Survey Of Invasive Lantana Camara At Makirovana-Tsihomanaomby Forest Complex, Eliza Pessereau
Independent Study Project (ISP) Collection
Lantana camara is a shrub known globally as an invasive pest that grows primarily in degraded areas. The species is known to exist at Makirovana-Tsihomanaomby, a forest complex in northeastern Madagascar with 167 endemic species of flora and fauna, several of which are on the IUCN Red List. The complex, specifically Tsihomanaomby forest, is used as a resource for the three rural communes that live on its outskirts, meaning that it experiences much human activity. The objective of this study was to survey the population of L. camara at two sites: one just outside of the Tsihomanaomby forest and one …
Phragmites Removal Increases Property Values In Michigan’S Lower Grand River Watershed, Paul Isely, Erik E. Nordman, Shaun Howard, Richard Bowman
Phragmites Removal Increases Property Values In Michigan’S Lower Grand River Watershed, Paul Isely, Erik E. Nordman, Shaun Howard, Richard Bowman
Journal of Ocean and Coastal Economics
The presence of Phragmites australis, an invasive wetland plant, negatively affects coastal property values and home prices rise with distance from Phragmites. Home prices increased as distance to Phragmites increased at a rate of $3.90/meter. Removing Phragmites from a property so that the next closest Phragmites was 400 m away results in a property value increase of over $1,500. Removing all Phragmites within 400 m of any property results in a total property value impact of $837,000. This generates about $13,457-$15,121 in additional property taxes each year once the prices and taxes adjust to the plant’s removal. We …
Pheasant Response To Lead Ingestion, Travis J. Runia, Alex J. Solem
Pheasant Response To Lead Ingestion, Travis J. Runia, Alex J. Solem
The Prairie Naturalist
Lead is toxic to all vertebrate species and ingestion of spent lead pellets from hunting is the primary method of exposure in birds. Both acute and chronic effects occur in response to lead ingestion including death, weight loss, and reduced body function, but the effect is highly variable among species. Most research has focused on lead ingestion impacts on waterfowl, but less is known about the effects of lead ingestion by upland game such as ring-necked pheasants (Phasianus colchicus). We gavage- fed zero, one, or three lead pellets to 90 (n = 30/group) captive-raised adult hen pheasants and monitored survival …

Long-Term Changes In Canada Goose Nest Success And Nest Densities At An Iowa Wetland Complex, Brenna N. Ness, Robert W. Klaver, Guy G. Zenner
The Prairie Naturalist
Giant Canada geese (Branta canadensis maxima) were extirpated from Iowa by the early 1900s due to unregulated hunting, egg gathering, and wetland drainage in the nineteenth century (Bishop 1978). Ef- forts to reintroduce Canada geese in Iowa began in 1964 (Bishop and Howing 1972) and involved releasing flightless adults and goslings at nearly 30 sites across the state (Zenner and LaGrange 1998a). In 1972, 13 flightless pairs were released at Rice Lake Wildlife Management Area (WMA; Bishop 1978). By 1989, the breeding population of Canada geese at Rice Lake WMA had increased to 420 nesting adults (G. G. Zenner, Iowa …

Assessing Parturition Date Synchrony For North Dakota Ungulates, Eric S. Michel, Jonathan A. Jenks, William F. Jensen
The Prairie Naturalist
Reproductive parameters such as conception date, and therefore parturition date, influence offspring characteristics such as sex ratio and birth mass. For example, late-conceiving reindeer (Rangifer tarandus) produced more female than male offspring compared to those who conceived early (Holand et al. 2006). Females that conceive later and therefore give birth later also can produce lighter offspring compared to those who conceive early (Schwartz et al. 1994, Holand et al. 2006). Because birth mass is positively related to adult body mass (Michel et al. 2015), conception and parturition date likely affect adult phenotype. In turn, this may influence survival because heavy …

Notes: Examining The Potential Competitive Effects Of Ventenata Dubia On Annual And Perennial Grasses, Shawn Mckay, Lesley R. Morris, Christopher E. Morris, Elizabeth A. Leger
The Prairie Naturalist
Portions of the United States are becoming increasingly dominated by annual species, with cheatgrass (Bromus tectorum L.) and medusahead (Taeniatherum caput-medusae [L.] Nevski) as the most common and well-known invaders (Bansal et al. 2014). Other invasive annual species also are present and increasing in abundance, including ventenata (Ventenata dubia [Leers] Coss.), an invasive annual grass that has been expanding within the Pacific Northwest, Great Basin, and Great Plains regions of the United States. Ventenata was first reported in North America in 1952 in Washington (Old and Callihan 1987) and has since spread to 7 western states in the USA (CA, …

Before describing what Flores’ book is, I must state what it is not. It is not a technical book designed for scholarly readers. Sources are not fully cited, and the bibliography is of limited scope. Nor is it a comprehensive book of all the megafauna of the Great Plains. Although chapters are devoted to extant species such as American bison (Bison bison), pronghorn (Antilocapra americana), and coyote (Canis latrans), there are only passing references to mule and white-tailed deer (Odocoileus hemionus and O. virginianus, respectively), elk (Cervus canadensis), and bighorn sheep (Ovis canadensis). Rather, Flores devotes chapters to grizzly bears …
Diel And Monthly Movement Rates By Migratory And Resident Female Pronghorn, Paul F. Jones, T. Andrew Hurly, Chelsea Jensen, Karl Zimmer, Andrew Jakes
Diel And Monthly Movement Rates By Migratory And Resident Female Pronghorn, Paul F. Jones, T. Andrew Hurly, Chelsea Jensen, Karl Zimmer, Andrew Jakes
The Prairie Naturalist
Animal movement patterns are variable, with certain species primarily being diurnal and others nocturnal. Pronghorn (Antilocapra americana) are regarded as diurnal animals moving predominately during daylight hours. Anecdotal accounts, however, suggest that pronghorn move during the night but the extent, frequency, and importance of these nocturnal movement behaviors are unknown. To evaluate movements, we combined global positioning system relocation data from collared female pronghorn in the Northern Sagebrush Steppe between 2003 and 2007 with sunrise/sunset data within a geographical information system platform. We assessed whether mean and maximum movement rates were influenced by diel period (dawn, day, dusk, and night), …

Nest success rates often are higher among cavity-nesting birds than those that nest in open cups or on the ground. Among cavity-nesting birds, woodpeckers have some of the highest rates of nest success. A review of woodpecker nesting ecology across species documented nest success ranging from 0.42 to 1.00 with a median of 0.80 (n = 84 populations), and that predation was low, ranging from 0.00 to 0.35 with a median of 0.13 (n = 33 populations). The constrained opening to a cavity nest limits predation to relatively small animals or those able to break open cavity walls. …

Use Of Satellite Trap Transmitters In Capturing Mountain Lions, Randy D. Johnson, Jonathan A. Jenks, Stephanie A. Tucker
The Prairie Naturalist
The use of safe and humane methods for the capture of wild animals is imperative in wildlife research, wildlife damage management, and feral animal control. When capturing animals successfully and humanely, several items must be addressed, including animal safety, personnel safety, non-target captures, and cost (Sikes et al. 2016). Additionally, public pressures against the use of traps have led to significant changes in trapping regulations across North America and beyond (Andelt et al. 1999, Darrow and Shivik 2008) and can place research projects at risk to loss of Institutional Animal Care and Use Committee (IACUC) approval (Larkin et al. 2003). …

The Prairie Naturalist
The trumpeter swan (Cygnus buccinator) is North America’s largest waterfowl species and breeds in wetland habitats across the northern United States, Alaska and Canada. Summer observations by ornithologists, including those of John James Audubon in 1843, indicated a substantial number of trumpeter swans were breeding in North Dakota prior to European settlement. However, the species was extirpated by the late 1800s and there were no subsequent breeding records for over a century (Stewart 1975). Since 2007, 5 recent nesting records indicate that trumpeter swan has returned as a regular breeding species in North Dakota.
