Evaluation Of Three Nest Searching Methods For Ring-Necked Pheasant, Jeffery W. Stackhouse, Kevin K. Sedivec, Benjamin A. Geaumont

The Prairie Naturalist

Ring-necked pheasant (Phasianus colchicus) are a highly sought after game bird and as such, much research has been conducted regarding their ecology (Warner 1981, Trautman 1982, Johnson and Knue 1989). Perhaps the most investigated aspect of pheasant ecology is the species’ reproductive season (e.g. Linder et al. 1960, Dumke and Pils 1979, Leif 1994) with many studies focusing on nesting habitat (Baskett 1947, Clark et al. 1999). Results from previous research have acknowledged the difficulty associated with locating pheasant nests in their preferred cover types (Hanson 1970, Evrard 2000). Studies of pheasant nesting ecology have been based on …

Dual Capture Of A Piñon Deer Mouse And A Silky Pocket Mouse Resulting In Consumption Of The Smaller Animal, Jon C. Pigage, Roger D. Peyton

The Prairie Naturalist

Intraspecific dual captures of rodents are uncommon, but not rare. There are several reports of brown rats (Rattus norvegicus), white-footed deer mice (Peromyscus leucopus), North American deer mice (P. maniculatus), western harvest mice (Reithrodontomys megalotis) and meadow voles (Microtus pennsylvanicus) caught simultaneously in the same trap (i.e. a door-closing live-trap; Davis 1955, Getz 1961, Blaustein and Rothstein 1978, Jenkins and Llewellyn 1981, Novak 1983). Some reports are incidental whereas others are interpreted as social associations or bonding between conspecifics. Interspecific dual captures are rarely reported in the literature. The earliest report of …

Red-Tailed Hawk Nesting In Kansas: Influence Of Landscape Characteristics, William Langley

The Prairie Naturalist

Factors that affect nest site selection in red-tailed hawks (Buteo jamaicensis) include the physical features surrounding the nest and landscape characteristics. Features surrounding nests include: tree height, tree diameter (dbh), percent canopy cover, slope, nest openness, and density of woody plants or shrubs (Titus and Mosher 1981, Bechard et al. 1990, Tietje et al. 1997, Actkinson et al. 2007). Landscape characteristics that influence nest-site selection by red-tailed hawks vary across regions. In Georgia, red-tailed hawks selected nest site in areas with greater area of agriculture and open pasture (Moorman and Chapman 1996), whereas in Oklahoma prairies, the hawks …

Associations Between Iron Concentration And Productivity In Montane Streams Of The Black Hills, South Dakota, Cari-Ann Hayer, Benjamin M. Holocmb, Steven R. Chipps

The Prairie Naturalist

Iron is an important micronutrient found in aquatic systems that can influence nutrient availability (e.g. phosphorus) and primary productivity. In streams, high iron concentrations often are associated with low pH as a result of acid mine drainage, which is known to affect fish and invertebrate communities. Streams in the Black Hills of South Dakota are generally circumneutral in pH, yet select streams exhibit high iron concentrations associated with natural iron deposits. In this study, we examined relationships among iron concentration, periphyton biomass, macroinvertebrate abundance, and fish assemblages in four Black Hills streams. The stream with the highest iron concentration (~5 …

Use Of Seeded Exotic Grasslands By Wintering Birds, Andrew D. George, Timothy J. O'Connell, Karen R. Hickman, David M. Lesliee Jr.

The Prairie Naturalist

Despite widespread population declines of North American grassland birds, effects of anthropogenic disturbance on wintering habitat of this guild remain poorly understood. We compared avian abundance and habitat structure in fields planted to the exotic grass Old World bluestem (Bothriochloa ischaemum; OWB) to that in native mixed-grass prairie. During winters of 2007–2008 and 2008–2009, we conducted bird and vegetation surveys in six native grass and six OWB fields in Garfield, Grant, and Alfalfa counties, Oklahoma. We recorded 24 species of wintering birds in native fields and 14 species in OWB monocultures. While vegetation structure was similar between field …

Temperatures are finally starting to cool a bit (for those of us in the northern Great Plains region) and Thanksgiving break is just around the corner.

I offer my reflections in the spirit of encouraging each of you to take a break from your professional obligations and spend time with friends and family enjoying nature and everything it has to offer this fall.

Salamander Colonization Of Chase Lake, Stutsman County, North Dakota, David M. Mushet, Kyle I. Mclean, Craig A. Stockwell

The Prairie Naturalist

Salt concentrations in lakes are dynamic. In the western United States, water diversions have caused significant declines in lake levels resulting in increased salinity, placing many aquatic species at risk (Galat and Robinson 1983, Beutel et al. 2001). Severe droughts can have similar effects on salt concentrations and aquatic communities (Swanson et al. 2003). Conversely, large inputs of water can dilute salt concentrations and contribute to community shifts (Euliss et al. 2004).

Chase Lake is a large, shallow, alkaline lake in east-central North Dakota most famously known for supporting one of the largest breeding colonies of the American white pelican …

A Simple Device For Measuring The Minimum Current Velocity To Maintain Semi-Buoyant Fish Eggs In Suspension, Julias S. Mueller, Brandon D. Cheek, Qingman Chen, Jillian Groeschel, Shannok K. Brewer, Timothy B. Grabowski

The Prairie Naturalist

Pelagic broadcast spawning cyprinids are common to Great Plains rivers and streams. This reproductive guild produces non-adhesive semi-buoyant eggs that require sufficient current velocity to remain in suspension during development. Although studies have shown that there may be a minimum velocity needed to keep the eggs in suspension, this velocity has not been estimated directly nor has the influence of physicochemical factors on egg buoyancy been determined. We developed a simple, inexpensive flow chamber that allowed for evaluation of minimum current velocity needed to keep semi-buoyant eggs in suspension at any time frame during egg development. The device described here …

A Northward Range Extension Of The Hispid Cotton Rat (Sigmodon Hispidus) In Missouri, Cody W. Thompson, Elmer J. Finck

The Prairie Naturalist

The hispid cotton rat (Sigmodon hispidus) is a widely distributed rodent with a geographic range extending from north-central Mexico to southern Nebraska and central Virginia and from southeastern Arizona east to Florida (Carleton et al. 1999, Peppers and Bradley 2000, Wilson and Reeder 2005) with isolated populations in Arizona (Bradley et al. 2012) and California (Clark 1972). Range expansions for the species have been well documented (Clark 1972, Farney 1975, Benedict et al. 2000, Wright et al. 2010, Wills et al. 2011). The majority of these range expansions have occurred across the Central Plains during the 20th century …

Whooping Cranes Consume Plains Leopard Frogs At Migratory Stopover Sites In Nebraska, Keith Geluso, Brad T. Krohn, Mary J. Harner, Michael J. Assenmacher

The Prairie Naturalist

Whooping cranes (Grus americana) currently consist of a single, wild population that migrates annually from breeding grounds at Wood Buffalo National Park, Canada, to wintering grounds on and around the Aransas National Wildlife Refuge along the Texas coast, USA (NRC 2005). This population reached a low of less than 20 individuals in 1941 (Allen 1952) but has rebounded to over 250 individuals (Chavez-Ramirez and Wehtje 2012, Gil-Weir et al. 2012). Whooping cranes migrate approximately 4,000 km each spring and autumn, traversing much of the North American Great Plains (Lewis 1995) and periodically landing along rivers, wetlands, and other …

Relationships Among Walleye Mercury, Selenium, Stable Isotopes, Size And Age, Mark J. Fincel, Robert P. Hanten, Shannon Minerich

The Prairie Naturalist

Bioaccumulation of mercury is well-documented in aquatic ecosystems and occurs as mercury is accumulated and passed up food chains (Kidd et al. 1995, Atwell et al. 1998, Downs et al. 1998). Trophic level correlations have been widely reported for mercury (Snodgrass et al. 2000) and other metals (Barron 1995). Generally, within a system, carnivores have the highest mercury loadings, omnivores intermediate and herbivores the lowest (Phillips et al. 1980). However, little research has focused on the differences in mercury bioaccumulation for a single species that ranges across multiple trophic levels (Burger et al. 2001).

Stable isotope analysis has expanded the …

The Envenoming Pandemic And The Misguided Views Of Snakes: Developing Sustainable Relationships Between Native Poisonous Snakes Of India And The Citizens Of Maharashtra Through The Use Of The Irula Model., Destiny Villanueva

Animal Science

Due to its vast population and general negative consensus regarding snakes, India is notorious for having more snakebite incidents than any other country. Snakes are simultaneously revered and feared in Indian religion and culture. This stigma is perpetuated through propaganda, family beliefs, and innate fears of snakes.These stigmas are more pronounced within rural areas, such as the region of Mahad within the state of Maharshtra. Envenoming is endemic in these areas, and others like them. The World Health Organization identified envenoming as one of the most neglected tropical diseases of the 21st century (Nature India, 2013). Additionally, both nonvenomous and …

Notes: Nesting Patterns Of Red-Tailed Hawks And Great-Horned Owls In South-Cen- Tral Kansas, William Langley

The Prairie Naturalist

Red-tailed hawks (Buteo jamaicensis) and great-horned owls (Bubo virginianus) can influence the nesting behavior of each other through direct competition for nesting sites. For instance, owls begin nesting before hawks and, thus, can use nests from the previous year and prevent hawks from occupying those sites (Orians and Kuhl- man 1956, Gilmer et al. 1983, Minor et al. 1993). However, both species sometimes kill the nestlings of the other (Craig- head and Craighead 1956, Bosakowski et al. 1989).

The objective of my study was to investigate nesting patterns of these two raptors at the edge of the tallgrass prairie over …

Research Notes Vs. Research Articles, Christopher N. Jacques

The Prairie Naturalist

Greetings GPNSS members! I hope this email finds you well, winding down another academic year, and looking forward to the summer field season. Warm temperatures, peak foliage, and heightened anticipation of the start of another field season are upon us following a long winter season and unusually wet spring for many of us across the Great Plains. Here in westcentral Illinois, wild turkeys are gobbling, neotropical migrants are singing and establishing breeding territories, and white-tailed deer are within days of giving birth to the next generation of fawns. Granted, there are many outdoor activities to participate in, though oppressive heat …

Distribution Of Burrowing Owls In East- Central South Dakota, Jiill A. Shaffer, Jason P. Thiele

The Prairie Naturalist

Western burrowing owl (Athene cunicularia hypugaea) populations have declined across much of western North America, particularly at the northern and eastern edges of the species’ breeding range (Martell et al. 2001, Murphy et al. 2001, Shyry et al. 2001, Skeel et al. 2001, Klute et al. 2003). In South Dakota, the burrowing owl is a summer resident that historically was relatively common throughout the state, but its range has decreased in recent decades, especially in the eastern half of the state (Whitney et al. 1978, South Dakota Ornithologists’ Union [SDOU] 1991, Peterson 1995). Tallman et al. (2002) described the species …

Contributions Of Stocked And Naturally Reproduced Rainbow Trout In The Deerfield Reservoir System, Jacob L. Davis, Jerry W. Wilhite, Greg Simpson, Michael E. Barnes, Kaite N. Bertrand, David W. Willis

The Prairie Naturalist

Deerfield Reservoir in the Black Hills of South Dakota and its tributary system are managed as hatchery supplemented rainbow trout (Oncorhynchus mykiss) fisheries. Three genetically unique strains of rainbow trout (Shasta, Erwin and McConaughy) are stocked into the system. Recently, juvenile rainbow trout of unknown origin were collected in the tributary system above Deerfield Reservoir, indicating potential natural reproduction. Understanding the genetic origins and ability of these rainbow trout to contribute to the fishery is essential in determining the proper management strategy for these waters. Our objectives were to 1) evaluate the genetic origins of potentially naturally reproduced rainbow trout …
