Semi-Melanistic White-Tailed Deer In Northern Wisconsin, Christopher N. Jacques, Keith R. Mccaffery, Jonathan Jenks, John T. Baccus

The Prairie Naturalist

Melanistic color morphs of white-tailed deer (Odocoileus virginianus) are differentiated from other recognized color morphs by having uniform black hairs on the dorsal surface with subdued black hairs on the ventral surface, dark face and ears, a distinctive mid-dorsal stripe extending from the head to the apex of the tail, and a tail with black dorsally and white ventrally (Baccus and Posey 1999). Melanism results from the overproduction of the skin pigment melanin and is considered rare in white-tailed deer populations (Severinghaus and Cheatum 1956, Sauer 1984, Smith et al. 1984). Semi-melanistic deer have the same dark pelage …

Winterkill And Biomass Of The Painted Turtle In A South Dakota Wetland, Steven G. Platt, Zannita Fast Horse, Warren Cross, Sylvio Mannel, Thomas R. Rainwater

The Prairie Naturalist

Winterkill occurs when drought conditions expose hibernating turtles to desiccation and lethaly cold temperatures. Winterkill is thought to represent a major source of mortality in northern populations of the painted turtle (Chrysemys picta), but few field observations are available. We herein reported on catastrophic winterkill among western painted turtle (C. pieta bellii) at Limestone Butte Lake (LBL) in western South Dakota during the winter of 2003-2004. Additionally, we used the carcasses of winterkilled turtles (n = 86) to estimate the standing crop biomass of the painted turtle at LBL (0.6 kg/ha). This was the only estimate …

Paddlefish Egg Deposition In The Lower Yellowstone River, Montana And North Dakota, Shannon E. Miller, Dennis L. Scarnecchia, Steven R. Fain

The Prairie Naturalist

We used passive egg collectors during May, June, and July of2003 and 2004 in the lower 50 river kiiometers (rkm) of the Yellowstone River, eastern Montana and western North Dakota, to detect egg deposition by spawning paddle fish (Polyodon spathula). Sampling yielded 292 eggs (46 in 2003 and 246 in 2004). All egg collections in 2003 occurred on the descending limb of the spring hydrograph but 99% of egg collections in 2004 occurred before the spring hydrograph began to descend. Catch-per-unit-effort (CPUE) in 2004 was about four times that of 2003. A combination of river conditions, in addition …

The Vascular Flora Of The Owens Peak Eastern Watershed, Southern Sierra Nevada, California, Naomi S. Fraga

Aliso: A Journal of Systematic and Floristic Botany

Owens Peak lies at the southern end of the Sierra Nevada within the Bureau of Land Management’s Owens Peak Wilderness Area in Kern County, California. The study site, ca. 50 square miles, encompasses Owens Peak’s eastern watershed, and ranges in elevation from 800–2600 m (2600–8400 ft). Granite rocks of the Sierra Nevada batholith underlie the study area. The eastern watershed of Owens Peak is botanically diverse, with 64 families, 230 genera, and 440 taxa currently documented. Floristic elements within the study area include the southern Sierra Nevada, Great Basin, and Mojave Desert. The flora previously was poorly documented, as discovered …

Cantua Dendritica (Polemoniaceae), A New Species From Peru, And Two New Cantua Names, J. Mark Porter, L. Alan Prather

Aliso: A Journal of Systematic and Floristic Botany

Cantua dendritica is described as new. This species is apparently restricted to the region around Paucartambo, Department of Cusco, Peru. Related to, and frequently identified as, Cantua flexuosa, this new species differs in its glandular calyx, highly branched trichomes on the margin of the corolla lobes, and its softly herbaceous, glandular pilose leaves. In addition, two new names are proposed in Cantua for the two species of Huthia that have been transferred to Cantua, C. volcanica (formerly Huthia caerulea), and C. mediamnis (formerly H. longiflora).

Evaluating Vascular Plant Composition And Species Richness On Horn Island, Mississippi, Using Passive And Active Remote Sensing In Conjunction With Ground Based Measurements, Kelly Lynn Lucas

Dissertations

Barrier island vegetation is subjected to chronic abiotic stressors combined with periodic storm events that favor species adapted to harsh environments. These islands are the first landforms to be affected by changes in coastal subsidence and sea-level rise. Evaluating changes in vegetation is important for understanding the impact of global climate change on coastal environments.

This study assesses vegetation composition and plant species richness on Horn Island, Mississippi using ground data in conjunction with remotely sensed spectral and LIDAR data. The goals of this research are to: 1) classify and map vegetation composition on Horn Island using hyperspectral and LIDAR …

Marketing Of Forest Reproductive Material: The Use Of Microsatellites For Identification Of Registered Tree Clones In Finland, Leena Koviuranta, Kari Leinonen, Pertti Pulkkinen

Aspen Bibliography

According to the current legislation on the marketing of forest reproductive material, tree clones marketed in the EU must have certain traits which make them identifiable, and these traits must have been accepted and registered by an official body. Due to this obligation, there is a need for reliable, functional and practicable methods for specifying these distinctive characters. We have developed a clone identification method for European and hybrid aspens and curly birch, based on nuclear microsatellites, which can be used for determining the distinctive characters mentioned in the directive. For aspens, we have used 18 loci, of which nine …

Plant Community Response To Fire: A Chronosequence Study, Scott R. Abella, E. Cayenne Engel

Public Policy and Leadership Faculty Research

Fires are becoming more prevalent events across the landscape in the southwestern US. Over the next several decades the already arid southwest is predicted to become warmer and drier, with longer summers, and an increase of “extreme” weather events such as lightening inducing thunderstorms. While the “hotter and drier” forecast may indicate less abundant plant life, and thus less available biomass for fuel, exotic invasive plant species are becoming more dominant across the landscape with increases in human travel and commerce. Exotic species (particularly many of the invasive grasses) are adding fuel for the fires to burn when the annuals …

West Nile Virus Antibodies In Breeding North Dakota Icterids, Jennifer L. Newbrey, Wendy L. Reed

The Prairie Naturalist

Exotic infectious diseases can have devastating effects on the distribution and abundance ofnaYve wildlife species (Friend et al. 2001). West Nile Virus (WNV) is an exotic disease that was introduced into North America in 1999 and has resulted in the deaths of tens of thousands of birds (Marra et al. 2004). The natural cycle of WNV involves Culex spp. mosquitoes as principle vectors and birds as principle hosts, although humans, horses, and other mammals can become incidental hosts (Lanciotti et al. 2000). Because the virus can be fatal, outbreaks have become a national health concern for the human population, an …

Review Of Oology And Ralph's Talking Eggs By Carrol L. Henderson, Kristin R. Johnson

The Prairie Naturalist

Ralph Handsaker was an Iowan farmer whose "ravenous curiosity" (page 4) about the natural world inspired him to become an oologist, or egg collector. This book tells the story of Handsaker's eggs, contained in two large cabinets that remained hidden in the living room of his boarded-up house after his death in 1969, until they were rediscovered in 2003 and shown to the author, wildlife conservationist, and photographer, Carrol Henderson. Ralph's eggs can "talk" by virtue of Henderson's chronicle-using the eggs as guides-of not only Ralph's own passion for natural history and egg collecting, but also the history of conservation …

Influence Of Temperature And Discharge On Reproductive Timing Of Common Carp In A Northern Great Plains River, Tim Resseguie, Steve Kelsch

The Prairie Naturalist

Reproductive timing of common carp (Cyprinus carpio) was examined in the Red River of the North and compared with environmental factors that might have triggered spawning during 1999 and 2000. We estimated spawn dates for individual common carp larvae collected in the drift by back-calculating from datc of capture and by accounting for developmental stage at capture and water temperature during the period of egg incubation. Reproductive timing was compared with discharge and water temperature to determine which of these likely might be a synchronizing cue for spawning of common carp in the Red River basin. In both years of …

Review Of Roger Tory Peterson: A Biography By Douglas Carlson, Laura Erickson

The Prairie Naturalist

August 28, 2008, marks the centennial of Roger Tory Peterson's birth, and books related to the most prominent naturalist of the twentieth century have been sprouting up everywhere. I was disappointed that Douglas Carlson shied away from examining Peterson's personal life to provide insights into the forces and relationships that shaped, and were shaped by, this man so consumed with birds. Instead, Carlson focuses almost entirely on Peterson's work, writing, "Because his death is so recent, there are many who have a personal investment in his story; beyond a request for an interview, no attempts have been made to invade …

Raptor Use Of Artificial Perches At Natural Areas, City Of Fort Collins, Colorado, G. W. Witmer, Michael Pipas, Patrick Burke, David Rouse, Donna Dees, Karen Manci

The Prairie Naturalist

The black-tailed prairie dog (Cynomys ludovicianus) remains a critical element of the prairie ecosystem even though its numbers and occupied range have declined dramatically since the arrival of Europeans in North America (Antol in et al. 2002). Prairie dog colonies are used by many species of wildlife and help maintain high levels of biodiversity (Kotliar et al. 1999). In the urban-suburban setting, the occurrence of prairie dog colonies also provides opportunities for wildlife viewing and environmental education. Unfortunately, prairie dogs also can come into conflict with humans, especially in the urban-suburban setting, where they cause vegetation and property …

Low Reproductive Success Of Mallards In A Grassland-Dominated Landscape In The Sandhills Of Nebraska, Johann A. Walker, Zach J. Cunningham, Mark P. Vrtiska, Scott E. Stephens, Larkin Powell

The Prairie Naturalist

The Sandhills of Nebraska comprise approximately 5,000,000 ha of native grassland interspersed with numerous groundwater-fed wetlands. A substantial population of the mallard (Anas platyrhynchos) nests in this region. Previous investigations of nest survival probability of ducks in the Sandhills have estimated surprisingly low rates of nest survival for a grassland-dominated landscape. These investigations were conducted on public lands and most nest searching took place near wetlands where activity of nest predators might be highest. We predicted that mallards would nest at varying distances from wetlands and that survival probability of a representative sample of duck nests would increase …

Breeding By The Snowy Plover In North Dakota And South Dakota, Carol Aron, Paul Van Ningten, Michael Rabenberg, Cheryl Jacobs, Greg Pavelka, Ricky D. Olson

The Prairie Naturalist

The snowy plover (Charadrius alexandrinus) is a small shorebird that breeds on unvegetated beaches along coastlines, rivers, and alkaline lakes. In North America, its breeding distribution extends along the coasts of California, Oregon, and southern Washington, where the population is listed as federally threatened (USFWS 1993), and an interior population occurs on wetlands in western and central states and central Mexico (Page et al. 1995). There have been rare breeding reports in Montana, Wyoming, and Saskatchewan (Page et al. 1995), but no documented breeding records in North Dakota or South Dakota. However, the United States Army Corps of Engineers reported …

Drought And Salinity Tolerance In Common Agrostis Species., Carol Auer, Collin Ahrens

Plant Science Presentations and Proceedings

Our research examines plant gene flow and the impacts from environmental release of genetically-modified plants. Plant gene flow is a natural process that occurs when pollen from one plant lands on the flower of another plant and produces a hybrid offspring. Gene flow can produce hybrid offspring with new traits that could change the ability of the plant to survive and spread. If hybrid offspring have some advantage in the environment, they could become invasive and/or affect other components of our ecosystems. In the near future, the federal government may approve the use of a genetically engineered herbicide-resistant (HR) Agrostis …

If Hybrids Go Wrong: Assessing Potential Environmental Risk From Release Of Herbicide-Resistant Creeping Bentgrass (Agrostis)., Carol Auer, Collin Ahens

Plant Science Presentations and Proceedings

Genetically-modified (GM) plants need to be assessed for their benefits and risks before they are released into the environment. At present, GM grasses are being developed to improve sports turf and biofuels crops (e.g. switchgrass). How will genetic engineering of perennial grasses alter the distribution of these grasses in natural areas and managed landscapes? Can we use research data to predict future gene flow, weediness, or invasion? These are some of the important questions in ecological risk assessment of GM perennial grasses. We have initiated five research projects to characterize gene flow and potential ecological risk from herbicide-resistant (HR) creeping …

A Watershed Analysis Of Pattee Pond: Implications For Water Quality And Land Use Management, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College

Colby College Watershed Study: Pattee Pond (2008, 1992)

The Colby Environmental Assessment Team (CEAT) investigated the impact of land use patterns on the water quality of Pattee Pond in Winslow, Maine, during the summer and fall of 2008. Physical, chemical, and biological characteristics of water quality were analyzed to evaluate the current health of the lake. Data collected were compared with previous studies conducted by the Maine Department of Environmental Protection (DEP) and CEAT to examine changes in water quality and land use over time. Trends in Pattee Pond water quality suggest an improvement since the 1970s. However, the lake is still experiencing algal blooms resulting from phosphorus …
