Where Do They Go When They Die?, Meridith L. Bartley

Mahurin Honors College Capstone Experience/Thesis Projects

Food webs and matrices are vital to understanding feeding relationships and ecology. Adjacency matrices can be employed to present the direct relationships between predators and prey; these binary matrices utilize 0’s to denote no direct link and 1’s to denote a direct link. We analyzed a variety of published food webs ranging from pine forests in the United States to tussock grasslands in New Zealand. The food webs varied in number of distinguishable taxa present, functional diversity, climates and habitats. Consequently, we expect that our results are not specific to a given system. The published food webs lack flows from …

Tthe Immature Stages And Natural History Of Antirrhea Adoptiva Porphyrosticta (Watkins, 1928) In Eastern Ecuador (Lepidoptera, Nymphalidae, Morphinae), Harold F. Greeney, Philip J. Devries, Carla M. Penz, Rafael B. Granizo-T, Heidi Connahs, John O. Stireman Iii, Thomas R. Walla, Lee A. Dyer

Biological Sciences Faculty Publications

Here we describe the immature stages and ecological associations of Antirrhea adoptiva porphyrosticta Watkins, 1928 (Lepidoptera:Nymphalidae:Morphinae). The cloud forest bamboo, Chusquea scandens Kunth (Bambusoidea: Poaceae), serves as the larval food plant for this butterfly in eastern Ecuador, the first hostplant record for Antirrhea outside the family Arecaceae. The larvae of A. adoptiva porphyrosticta are superficially similar to those of other Antirrhea species. We also provide observations on adult and larval behavior. Caterpillars of this butterfly species are parasitized by tachinid flies, as well as by Ichneumonidae and a newly described braconid wasp.

Species Richness And Host Associations Of Lepidoptera-Attacking Tachinidae In The Northeast Ecuadorian Andes, John O. Stireman Iii, Harold F. Greeney, Lee A. Dyer

Biological Sciences Faculty Publications

Most of the unknown biological diversity of macro-organisms remaining to be discovered and described lies in the tropical regions of the world and consists primarily of insects. Those insects with parasitoid lifestyles constitute a significant portion of insect diversity, yet parasitoids are among the most poorly known of major insect guilds in the humid tropics. Here we describe and analyze the richness of one diverse taxon of parasitoids, flies in the family Tachinidae, reared from Lepidoptera as part of a biological survey of Lepidoptera and their parasitoids in one mid-elevation (2000 m) area in the northeast Ecuadorian Andes. One hundred …

Habitat Variation Among Aquatic Gastropod Assemblages Of Indiana, U.S.A., Mark Pyron, Jayson Beugly, Matthew Spielman, Jennifer Pritchett, Stephen J. Jacquemin

Biological Sciences Faculty Publications

We collected aquatic gastropods at 137 sites in lakes and streams of Indiana and tested for patterns of assemblages with environmental variables. The survey resulted in 32 species with a mean of 2.8 species at each site, and a mean abundance at each site of 144 individuals. Nonmetric multidimensional scaling (NMS) multivariate analyses resulted in watershed drainage area, water conductivity, substrate category frequency, and dissolved oxygen as significant correlates of gastropod assemblage structure. Gastropod assemblages of lakes were not significantly different than assemblages of streams in the ordination. Prosobranch taxa occurred in higher abundances than pulmonate taxa at sites with …

Third Report Of The North Dakota Bird Records Committee: 2004-2005, Dan Svingen, Ron E. Martin

The Prairie Naturalist

Since 1979, North Dakota's bird records committee has collected, evaluated, and archived documentations of rare bird occurrences in the state. In 2004 and 2005, this committee resolved 189 rare bird records. On the basis of these record reviews, six species were ad~ed to the North Dakota state bird list: mottled duck (Anas fulvigula), yellow-billed loon (Cavia adamsii), white-tailed kite (Elanus leucurus), little stint (Calidris minuta), glaucous-winged gull (Larus glaucescens), and great black-backed gull (Larus marinus). Four species were added to the list of nesting species within the state: snowy …

Effect Of Drought And Agriculture On Ring-Necked Pheasant Abundance, Nebraska Panhandle, Charles J. Randel Iii

The Prairie Naturalist

The objectives of my study were to detennine the effects of drought (e.g., Palmer Modified Drought Severity Index; PMDI, Bridges et at. 2001) and/or agricultural practices (e.g., conversion) on RNP abundance in the Nebraska Panhandle (NP).

My RNP survey data were found to be correlated negatively to drought condition (PMDI) in January, February, and April. This was supported by Snyder (1984) and Riley (1995), both of whom reported that decreased precipitation in spring affected RNP production in the western Great Plains and Iowa, respectively. Late winter and early spring drought affect subsoil moisture and decrease primary production (Kiesselbach et al. …

Common Raven Nests In North Dakota After 100-Year Hiatus, Melvin P. Nenneman, Todd A. Grant, Ron E. Martin

The Prairie Naturalist

Our observations represent the first documented nesting by the common raven in North Dakota since the late 1800's. Houston (1977) suggested that the expansion of the American crow onto the Canadian prairies was limited by the scarcity of trees for nest sites, which also might have limited the extent of the common raven. Aspen woodland has increased substantially in and around J. Clark Salyer National Wildlife Refuge since European settlement, due primarily to fire suppression and extirpation of large herbivores (Grant and Murphy 2005). Thus, plausibly these increases in woodland habitat might be providing nest sites necessary for the common …

Consequences Of More Extreme Precipitation Regimes For Terrestrial Ecosystems, S. D. Smith, C. Beier, Aimee T. Classen, Melinda D. Smith, Jana L. Heisler, S. W. Leavitt, Alan K. Knapp, D. Briske, Y. Luo, M. Reichstein, J. E. Bell, Philip A. Fay, R. Sherry, Benjamin Smith

Life Sciences Faculty Research

Amplification of the hydrological cycle as a consequence of global warming is forecast to lead to more extreme intra-annual precipitation regimes characterized by larger rainfall events and longer intervals between events. We present a conceptual framework, based on past investigations and ecological theory, for predicting the consequences of this underappreciated aspect of climate change. We consider a broad range of terrestrial ecosystems that vary in their overall water balance. More extreme rainfall regimes are expected to increase the duration and severity of soil water stress in mesic ecosystems as intervals between rainfall events increase. In contrast, xeric ecosystems may exhibit …

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 …

Non-Blackbird Avian Occurrence And Abundance In North Dakota Sunflower Fields, Dionn A. Schaaf, George M. Linz, Curt Doetkott, Mark W. Lutman, William J. Bleier

The Prairie Naturalist

Sunflower fields are well-documented as foraging habitat for fallmigrating blackbirds (Family Icteridae). There is, however, a paucity of information on the use of sunflower fields by non-blackbirds. We assessed non-blackbird use of 12 ripening sunflower fields in the Prairie Pothole Region of central North Dakota. From mid-August to mid-October 2000, we counted 4,129 individual birds, consisting of 22 families and 61 species, in the sample fields and within 5 m of the field edges. We saw the largest number of birds from 18 September to 27 September. The Family Emberizidae (sparrows) accounted for 26% of the species and 20% of …

A Case Study Of A Successful Lake Rehabilitation Project In South-Central Nebraska, Peter J. Spirk, Brad Newcomb, Keith D. Koupal

The Prairie Naturalist

Cottonmill Lake, a 17.4 ha impoundment located in Buffalo County, Nebraska, was a fishery dominated by common carp (Cyprinus carpio). As a result of the poor sportfish populations, angler participation in May and June of 1993 was low (503 ± 210 angler hours) and angler catch rates for all fish species (0.5 ± 0.4 fish/angler hour) was less than desired. In 1995, before rehabilitation, bluegill (Lepomis macrochirus) trap net catch per unit effort (CPUE) was 1.5 ± 0.9, largemouth bass (Micropterus salmoides) catch per hour of electrofishing was 8.0 ± 0.5, and channel catfish (Ictalurus punctatus) …

Nest Site Preference And Nesting Success Of Upland Sandpiper On Grazing Systems In East Central North Dakota-, Blane A. Klemek

The Prairie Naturalist

require ranchers to move their cattle throughout the range from one paddock to another, thereby allowing formerly grazed paddocks to regenerate. This is beneficial in a number of ways: overgrazing is reduced, cattle weight-gains are improved, suitable nesting cover for ground nesting birds is produced, and the overall health of the grassland is enhanced (Sedivec and Barker 1991). The objectives of my study were to investigate nesting success of the upland sandpiper as a function of grazing regime. Specifically, I was interested in comparing nesting success between RGS and non-rotational grazing systems (NRGS) and to examine relationships between nest site …

Using Local Knowledge And Remote Sensing To Map Known And Potential Prairie-Chicken Distribution In Kansas, Michael E. Houts, Randy D. Rodgers, Roger D. Applegate, William H. Busby

The Prairie Naturalist

The greater prairie-chicken (Tympanuchus cupido) and lesser prairie-chicken (Tympanuchus pallidicinctus) have experienced considerable fluctuations in their range and distribution over time. Having current range maps would help wildlife managers and policy makers with decisions regarding prairie-chicken habitat. To create an updated and accurate map of the Kansas prairie-chicken range, a two-pronged approach was implemented. First, a map of potential habitat was created by using known habitat preferences and avoidance factors. Second, a preliminary map showing the distribution of greater and lesser prairie-chickens was created and mailed to regional experts for comments and edits. The returned edits …

Shifts In Southern Wisconsin Forest Canopy And Understory Richness, Composition, And Heterogeneity, David A. Rogers, Thomas P. Rooney, Daniel Olson, Donald M. Waller

Biological Sciences Faculty Publications

We resurveyed the under- and overstory species composition of 94 upland forest stands in southern Wisconsin in 2002–2004 to assess shifts in canopy and understory richness, composition, and heterogeneity relative to the original surveys in 1949–1950. The canopy has shifted from mostly oaks (Quercus spp.) toward more mesic and shade-tolerant trees (primarily Acer spp.). Oak-dominated early-successional stands and those on coarse, nutrient-poor soils changed the most in canopy composition. Understories at most sites (80%) lost native species, with mean species density declining 25% at the 1-m² scale and 23.1% at the 20-m² scale. Woody species have increased …

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 …

Aquatic And Terrestrial Habitat Use Of The Australian Freshwater Turtle, Chelodina Expansa, Ellyn Ercolano

Independent Study Project (ISP) Collection

Organisms select habitats that provide the best possible resources necessary to their survival. Organisms may occupy and utilize a home range which requires specific selection of components in their available habitat. Monitoring the threats to a species within their habitats is a crucial tool in conservation and management practices. The Murray-Darling Basin of south-eastern Australia has suffered alterations to its hydrology, flow regime, catchment size and usage, flooding cycles, as well as from vast removal of vegetation in the floodplains since European settlement in Australia in the mid-nineteenth century. Knowledge of the habitat use of a focal species can guide …

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 …

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 …
