Successional Changes And Habitat Selection In Hayfield Bird Communities, Eric Bollinger

Faculty Research & Creative Activity

I examined the effects of successional changes in vegetation on the breeding dispersion of grassland birds in hayfields in New York. I sampled vegetation and counted birds in 90 hayfields of various ages (i.e. number of years since planting) and sizes that were originally planted to a legume-dominated seed mixture. I also resampled a subset of these fields two years later. Over time, these hayfields changed from tall, dense, homogeneous stands of legume-dominated vegetation to short, sparse, patchy stands of grass-dominated vegetation. Fields of all ages were dominated by introduced plant species. Red-winged Blackbirds (Agelaius phoeniceus), the most common bird …

Comparison Of Sweet Corn Vigor With Ions And Sugars In Seed Leachate Of Five Isolene Pairs With Two Endosperm Types, Marla K. Faver

Masters Theses

Supersweet corn contains more sugar and less starch than traditional sweet corn which increases the sweetness of the kernel. Supersweet corn has increased in consumer popularity due to its sweeter flavor and ability to retain this sweeter flavor longer than traditional sweet corn. Two sweet corn (Zea mays L. var. rugosa) endosperm types (traditional and shrunken-2) are popular with consumers. The problem growers face with supersweet cultivars (shrunken-2) is poor seed vigor as shown by low field emergence and non-uniform stands.

Field emergence of plants was compared to laboratory germination for 5 sweet corn isoline pairs (genetically identical except for …

Egg Removal By Brown-Headed Cowbirds: A Field Test Of The Host Incubation Efficiency Hypothesis, Douglas R. Wood

Masters Theses

Obligate brood parasites, like the Brown-headed Cowbird (Molothrus ater), lay their eggs in the nests of host species, usually to the detriment of the host's reproductive effort. In addition, Brown-headed Cowbirds often remove one or more host eggs near the time of parasitism. Although several hypotheses exist, the adaptive significance of egg removal has not been clearly established. Peer and Bollinger (in press) proposed the host incubation efficiency hypothesis which states that the number and size of host eggs influences the incubation efficiency of a parasitic egg. Thus, host egg removal by cowbirds should increase the parasitic egg's …

Reproductive Success Of Grassland Birds At East-Central Illinois Airports, Eric L. Kershner

Masters Theses

We determined the densities and reproductive success of birds on airport grasslands in east-central Illinois. Seven airports were sampled between 10 April and 15 August 1994 in Clark, Coles, Crawford, Douglas, Edgar, Macon and Richland counties. Nineteen species were detected on the airport grasslands and 147 nests were found representing six different species. Eastern meadowlarks (Sturnella magna) were the most abundant nesting species found; 105 out of the 147 nests (71%). Other nesting species included: grasshopper sparrow (Ammodramus savannarum), savannah sparrow (Passerculus sandwichensis), red-winged blackbird (Agelaius phoeniceus), song sparrow (Melospiza melodia) and horned lark (Eremophilia alpestris). Overall nest success was …

A Faunal Study Of The Mecoptera (Insecta) Of Rocky Branch Nature Preserve, Clark County, Illinois, Jimmie W. Griffiths

Masters Theses

The Mecoptera (Insecta) of the Rocky Branch Nature Preserve located near Clarksville, Clark County, Illinois are described. Specimens were collected by diurnal netting, Malaise traps, pitfall traps, and flight traps. Specimens from Rocky Branch in the collections of Eastern Illinois University, the Illinois Natural History Survey at Champaign-Urbana, and Hastings College, Nebraska, were also examined.

A total of 805 specimens from Rocky Branch were collected and/or examined. Nine species representing three families were identified: three Panorpidae (Panorpa speciosa, P. helena and P. banksi); five Bittacidae (Hylobittacus apicalis, Bittacus strigosus, B. stigmaterus, B. pilicornis …

Lichen Use By Larval Leucochrysa Pavida (Neuroptera:Chrysopidae), Penni Jo Wilson

Masters Theses

Leucochrysa pavida is a species of green lacewing (Neuroptera:Chrysopidae) that uses lichen fragments to build a larval debris "packet." The "packet" is eventually used to form a cocoon used during pupation. Only minute lichen fragments are harvested for formation of the packets which makes identification of the actual lichens utilized difficult using morphological characteristics. For this reason, thin-layer chromatography was employed. The thin-layer chromatographic process identifies acetone-soluble lichen chemicals that are formed in lichen thalli. By comparing the chemistry of lichen communities at Tower Rock Recreation Area in Hardin County, Illinois, with the chemicals identified during thin-layer chromatography of larval …

Effects Of Ozone During Soybean Seed Development On Seed Vigor, Karen A. Gerlach

Masters Theses

Soybean (Glycine max L. Merr. cv 'Essex', 'Forrest' and 'Clark') seed were obtained from Dr. Mulchi of the University of Maryland. Seed from 1989 and 1990 were from plants which were exposed to three regimes of ozone during seed development including charcoal-filtered (no ozone), non-filtered (ambient ozone), and non-filtered + 40 n11^-1 O₃. Seed from 1994 were developed with four pollutant regimes of ozone during seed development including charcoal-filtered (no ozone), non-filtered (ambient ozone), non-filtered + 40 n11^-1, and non-filtered + 500 u11^-1 CO₂. The objective of this study was to assess …

A Comparison Of Two Isotonic Resistance Training Routines For Individuals With Above Average Strength, Craig L. Kruse

Masters Theses

The purpose of this study was to determine if individuals, possessing above average strength in the bench press exercise, would improve their 1RM more by using an experimental resistance training program as compared to a program of a more traditional nature.

Seventeen male subjects between the age 18 and 26 years, mean age 21.8 years, who were considered to have an above average strength level in the bench press exercise (a bench press strength to body weight ratio, S/BW, greater than 1.00) participated in this study. The subjects had an average S/BW of 1.17. All the subjects trained three alternate …

Genetic Structure Of Mosquitofish Populations In The Altamaha And Ogeechee Drainages Of Georgia: Reporting An Undescribed Form In The Ocmulgee River, Jose D. Hernandez-Martich, James M. Novak, Michael H. Smith, Paul E. Johns

Faculty Research & Creative Activity

An electrophoretic survey of genetic variation in mosquitofish populations of the Altamaha and Ogeechee drainages in Georgia revealed significant divergence (fs,=O.270) among populations within the Altamaha. Cluster analysis showed two lineages: one formed by populations from the Ogeechee drainage and the eastern and central Altamaha branches and another consisting of populations from the Ocmulgee River, the westernmost branch of the Altamaha drainage. These lineages may represent two independent forms. Average modified Rogers’ genetic distance was 0.25% between the two groups. The O_cmulgee lineage had significantly higher multilocus heterozygosity (H=0.206) than the other one (I-/=0.120). The high heterozygosity in the Ocmulgee …
