A Case Study Of A Successful Lake Rehabilitation Project In South-Central Nebraska, Peter J. Spirk, Brad Newcomb, Keith D. Koupal Sep 2008

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) …

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 …


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 Sep 2008

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 …


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 Sep 2008

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 …


Nest Site Preference And Nesting Success Of Upland Sandpiper On Grazing Systems In East Central North Dakota-, Blane A. Klemek Sep 2008

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 …


Semi-Melanistic White-Tailed Deer In Northern Wisconsin, Christopher N. Jacques, Keith R. Mccaffery, Jonathan Jenks, John T. Baccus Sep 2008

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 …

Conversion Of Traditional Observation-Based Botany Labs To Investigative Inquiry Learning, Hajara Mahmood Aug 2008

Conversion Of Traditional Observation-Based Botany Labs To Investigative Inquiry Learning, Hajara Mahmood

Masters Theses & Specialist Projects

“Tell me and I forget, show me and I remember, involve me and I understand.” - Chinese Proverb. Involvement in learning implies possessing skills and attitudes that permit students to seek resolutions to questions and issues while constructing new knowledge.

Low enrollment in Plant Biology and Diversity and upper level plant science courses has been noticed at Western Kentucky University. In addition, graduating students performed below the national average on the senior assessment examination in the area of botany content knowledge offered by WKU’s Biology Department. This may be due to the fact that observation-based botany has been taught in …


Paddlefish Egg Deposition In The Lower Yellowstone River, Montana And North Dakota, Shannon E. Miller, Dennis L. Scarnecchia, Steven R. Fain Aug 2008

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 …
