Notes: River Otters Use Agricultural Field Along The Turtle Riveri In Eastern North Dakota As Crossover And Latrine Area, Maggie D. Triska, Steven C. Loughry, Thomas L. Sergass

The Prairie Naturalist

Recently, the Nearctic river otter (Lontra canadensis) has been re-colonizing portions of eastern North Dakota. The landscape in eastern North Dakota is dominated by agricultural fields and pastures, habitats which have received little research attention related to otter habitat use. During 2008, we searched shorelines to detect otter latrines, which is a common method for determining otter presence. Generally, latrines are locations along bodies of water where otters deposit scats, urine, and glandular secretions for olfactory communication, and groom, wrestle, and play, which may mat vegetation. In the northeastern United States, inland riverine system studies have shown latrines …

Calodium Hepaticum In White-Tailed Jackrabbits In South Dakota, Dustin J. Schaible, Charles D. Dieter, Regg D. Neiger, Michael B. Hildreth

The Prairie Naturalist

White-tailed jackrabbits (Lepus townsendii) are common on the prairie, and an important species in prairie food webs (Lim 1987). Although it has been suggested that jackrabbits have cyclic populations (Donoho 1972, Gross et al. 1974, Anderson and Shumar 1986), there is concern that a general downward trend exists in populations in the Northern Great Plains (Feldhamer et al. 2003). Disease incidence in white-tailed jackrabbits is poorly known (Feldhamer et al. 2003), but may be an important factor in population changes. Tularemia, a disease caused by bacteria (Francisella tularensis), occurs throughout the Northern Hemisphere and can affect many mammals including hares, …

Resource Selection By Elk At Two Spatial Scales In The Black Hills, South Dakota, Mark A. Rumble, R. Scott Gamo

The Prairie Naturalist

Understanding resource selection by elk (Cervus elaphus) at multiple spatial scales may provide information that will help resolve the increasing number of resource conflicts involving elk. We quantified vegetation at 412 sites where the precise location of elk was known by direct observation and 509 random sites in the Black Hills of South Dakota during 1998– 2001. We obtained stand level variables from geographic information system coverages for a 250 m buffer around elk and random sites. We used classification and regression trees to simultaneously evaluate environmental thresholds of resources selected by feeding and bedded elk at the site and …

Multiple Bats Entangled On Cactus, Jon C. Pigage, Richard L. Bunn

The Prairie Naturalist

Accidental deaths of bats by entanglement on plants and barbed wire are common (McNicholl 1988, Norquay et al. 2010). It has been hypothesized these incidents involve miscalculations by bats on how close they fly to plants or barbed wire or when chasing insects highly concentrated around vegetation (Norquay et al. 2010). Once the bats hit the plants or barbed wire, they become entangled and or impaled while struggling to free themselves. The earliest reports involved little brown bats (Myotis lucifugus) and unidentified bats entangled on burdock, Arctium sp. (Lyon 1925, Little 1925). Additional reports of bats becoming entangled in plants …

First Record Of The Least Weasel In The Black Hills Of South Dakota, Tim R. Mullican

The Prairie Naturalist

The least weasel (Mustela nivalis) is a circumboreal species, occurring in North America from Alaska to the Appalachian Mountains (Jones et al. 1983). In the Great Plains, the least weasel recently expanded its range southward through Nebraska (Benedict et al. 2000) and Kansas (Choate et al. 1979, Bailey and Terman 1986) into Oklahoma (Clark and Clark 1988). Also, in recent decades, the least weasel has expanded from eastern and central Nebraska into western Nebraska (Benedict et al. 2000). In South Dakota, least weasels have been previously reported from the eastern 3/4 of the state (Jones et al. 1983, Higgins et …

Phragmites Australis In South Dakota: Historical Distribution And Environment, Carol A. Johnston, Kayla L. Miller

The Prairie Naturalist

Common reed, Phragmites australis, has long been a component of Northern Plains wetlands, but impending invasion by the non-native P. australis haplotype M may displace native haplotypes in the future. To increase understanding of historical Phragmites occurrence, we developed a geographic information system (GIS) protocol to improve the georeferencing of specimens from South Dakota herbaria, and mapped the distribution of Phragmites relative to geology, physiographic regions, and water bodies. There were 91 Phragmites herbarium specimens from South Dakota and adjacent Wyoming. Phragmites collections occurred in nearly all physiographic regions of the state, with concentrations occurring in the Prairie Coteau of …

Crustaceous Zooplankton Transfer Between A Floodplain Wetland And The Missouri River, Shannon J. Fisher

The Prairie Naturalist

Floodplain interactions are a critical riverine ecosystem function, including zooplankton transfer. Floodplain alternations have had an assumed impact on zooplankton productivity. I assessed floodplain wetland and main channel densities of crustaceous zooplankton, alluding to organism transfer in the Missouri River, North Dakota. Significant t-test differences (P < 0.05) were present between backwater and channel habitat zooplankton densities in 83, 75, 83, and 50% of the sample periods for cyclopoid copepods, copepod nauplii, Daphnia spp., and Bosmina spp. respectively, suggesting the presence of uncoupled zooplankton dynamics during portions of each annual cycle. Two relationships with increased flows were found, including a biologically significant decrease (P = 0.09) of backwater copepod nauplii numbers and a significant increase (P = 0.02) in the channel density of Daphnia spp. During the highest flow periods, fewer significant differences in zooplankton densities were present between the backwater and channel habitats, indicating moderate homogenization.

Population Dynamics Of The Western Prickly Pear, Opuntia Macrorhiza (Cactaceae), Kathleen H. Keeler, Brigitte Tenhumberg

School of Biological Sciences: Faculty Publications

Although most cacti that have been studied are long lived, following individually marked plants in Boulder County, Colorado, for >7 years, we determined that average life span of Opuntia macrorhiza, the western prickly pear, is 3 years. A few individuals probably live >10 years. Vegetative reproduction, produced by rooting of cladodes, exceeded reproduction by germination and establishment from seeds. Both types of new recruits, from vegetative reproduction and seeds, had higher death rates than established plants. Size and frequency of flowering increased with age, although size both increased and decreased, sometimes dramatically, between years. Flowering correlated more strongly with …

Habitat Selection By Female Swift Foxes (Vulpes Velox) During The Pup- Rearing Season, Indrani Sasmal, Jonathan A. Jenks, Troy W. Grovenburg, Shubham Datta, Greg. M. Schroeder, Robert W. Klaver, Kevin M. Honness

The Prairie Naturalist

The swift fox (Vulpes velox) was historically distributed in western South Dakota including the region surrounding Badlands National Park (BNP). The species declined during the mid-1800s, largely due to habitat loss and poisoning targeted at wolves (Canis lupis) and coyotes (C. latrans). Only a small population of swift foxes near Ardmore, South Dakota persisted. In 2003, an introduction program was initiated at BNP with swift foxes translocated from Colorado and Wyoming. We report on habitat use by female swift foxes during the pup-rearing season (May–July) in 2009. Analyses of location data from 13 radiomarked female foxes indicated disproportional use (P < 0.001) of some habitats relative to their availability within swift fox home ranges. Swift foxes used grassland (ŵ = 1.01), sparse vegetation (ŵ = 1.43) and prairie dog towns (ŵ = 1.18) in proportion to their availability, whereas they were less likely to use woodland (ŵ = 0.00), shrubland (ŵ = 0.14), pasture/agricultural-land (ŵ = 0.25) and development (ŵ = 0.16) relative to availability. Swift foxes typically are located in habitats that provide greater visibility, such as shortgrass prairie and areas with sparse vegetation; which allow detection of approaching coyotes (e.g., primary predator of swift foxes).

Distribution Of Crayfish Species In Select North Dakota Streams, Cari-Ann Hayer, Terrance L. Velazquez, Mclain S. Johnson, Brian Graeb

The Prairie Naturalist

Crayfish have an integral role in aquatic ecosystems, serving as herbivores, predators, detritivores, and prey for fishes and other aquatic and terrestrial animals (Momot 1995, Taylor et al. 1996, Martin 1997). Many crayfish populations are currently declining as a result of habitat alteration (Taylor et al. 1996) and invasive predators (e.g., rusty crayfish Orconectes rusticus [Girard; Lodge et al. 2000]). Knowledge of crayfish distribution and biology in North America and specifically North Dakota is sparse or lacking (Taylor et al. 1996) and baseline information is necessary to identify effects of anthropogenic alterations. Early inventories documented 3 crayfish species in North …

A New Species Of Vaejovis From Prescott, Arizona (Scorpiones: Vaejovidae), Richard F. Ayrey, Michael E. Soleglad

Euscorpius

A new scorpion species, Vaejovis crumpi, sp. nov., is described from Prescott, Yavapai Co., Arizona. This species is related to V. paysonensis Soleglad, 1973, and the “sky island” species of southern Arizona. V. crumpi is compared to the seven Vaejovis species currently reported for Arizona, in particular to V. paysonensis.

Wetland Management Guidelines For Nebraska's Wildlife Management Areas, Ted Lagrange, Randy Stutheit

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Prior to Euro-American settlement, wetlands covered about 6% of the Nebraska landscape. Since settlement, the state’s wetlands have suffered serious decline. For example, approximately 90% of Rainwater Basin playa wetlands and 90% of the eastern saline wetlands have been destroyed or are highly degraded. Remaining wetlands are threatened by conversion to other uses (e.g. agriculture), invasive and aggressive vegetation, siltation, and lack of proper management. Only through sound management can the wetlands on our Wildlife Management Areas (WMA) be preserved for the citizens of Nebraska, as well as the native plants and wildlife dependent on them.

Traversing Swanton Road, 5th Ed., James A. West

Academic, Government & Associated Organizational Research Resources

Situated at the northwest end of Santa Cruz County and occupying circa 30 square miles of sharply contrasted terrain, the Scott Creek Watershed concentrates within its geomorphological boundaries, at least 10-12% of California's flora, both native and introduced. Paradoxically, the use/abuse that the watershed has sustained over the past 140+ years, has not necessarily diminished the biodiversity and perhaps parallels the naturally disruptive but biologically energizing processes (fire, flooding, landslides and erosion), which have also been historically documented for the area for +60 years. This is an early edition of an extensive document by James A. West. Please visit the …

The Genus Butheoloides Hirst, 1925 (Scorpiones, Buthidae) In Morocco, With A Description Of А New Species, Wilson R. Lourenço, Oulaid Touloun, Ali Ali Boumezzough

Euscorpius

A new species belonging to the genus Butheoloides Hirst, 1925 (subgenus Butheoloides Hirst, 1925) (Scorpiones, Buthidae) is described from two localities in Morocco: north of Sidi Ifni in the southern coast and Sidi Moussa west of Tiznit. With the description of Butheoloides (Butheoloides) littoralis sp. n., the total number of species of this genus known from Morocco is raised to five. This makes Morocco the region in Africa with the highest diversity for Butheoloides species.

Review Of Nature's Ghosts: Confronting Extinction From The Age Of Jefferson To The Age Of Ecology. By Mark V. Barrow, Jr., Peter A. Bednekoff

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

The saving of bison occupies a central place in Nature's Ghosts, but Mark Barrow's chronicle extends over a century both before and after. The story starts with Thomas Jefferson and fossils that came to be recognized as mastodons, mammoths, and giant ground sloths. "Jefferson and most of his contemporaries were certain that the natural world was orderly, static, and new." In such a worldview, extinction was unthinkable. Fossil evidence plus the historical extinctions of dodos, moas, and great auks forced reconsideration.

This book ranges across centuries and continents, and only a few parts of it are explicitly about the Great …

We report the draft genome sequence of the red harvester ant, Pogonomyrmex barbatus. The genome was sequenced using 454 pyrosequencing, and the current assembly and annotation were completed in less than 1 y. Analyses of conserved gene groups (more than 1,200 manually annotated genes to date) suggest a high-quality assembly and annotation comparable to recently sequenced insect genomes using Sanger sequencing. The red harvester ant is a model for studying reproductive division of labor, phenotypic plasticity, and sociogenomics. Although the genome of P. barbatus is similar to other sequenced hymenopterans (Apis mellifera and Nasonia vitripennis) in …

Comparative genomic analyses of primates offer considerable potential to define and understand the processes that mold, shape, and transform the human genome. However, primate taxonomy is both complex and controversial, with marginal unifying consensus of the evolutionary hierarchy of extant primate species. Here we provide new genomic sequence (~8 Mb) from 186 primates representing 61 (~90%) of the described genera, and we include outgroup species from Dermoptera, Scandentia, and Lagomorpha. The resultant phylogeny is exceptionally robust and illuminates events in primate evolution from ancient to recent, clarifying numerous taxonomic controversies and providing new data on human evolution. Ongoing speciation, reticulate …
