Nesting Dynamics Of The Eastern Bluebird (Sialia Sialis) In Southeastern Illinois, Susan E. Nelle

Masters Theses

Data collected from 1981 through 1988 from an Eastern Bluebird (Sialia sialis) nesting box trail, involving 512 nests and 2176 eggs, in Crawford County, Illinois, were analyzed and compared to similar published works. The average nesting season lasted 167.4 days, ran from 17 March through 31 August, and was divided into three breeding peaks (or phases). Most breeding pairs were observed with either one or two clutches per season; however, triple-brooded pairs were also present, the clutches of which coincided well with the three peaks. Most data showed a decrease as the season progressed. For example, mean clutch …

Some Factors Affecting Male Mating Success In The Giant Waterbug (Belostoma Flumineum Say), Karyn S. Crisman

Masters Theses

Giant waterbugs (Subfamily Belostomatinae) are interesting in that males provide exclusive post-copulatory care of young. This unusual behavior makes this species an excellent study system for investigations of sexual selection theory because in such systems, sex role reversals are predicted. Previous studies indicate that role reversal in giant waterbugs is not complete because males still court females. It is assumed that from this courtship display females can assess male quality and "choose" a superior male. If some males are chosen over others then differential mating success results. This study was undertaken to ascertain some of the factors that affect male …

Ecology And Interspecific Relationships Of The Painted Turtle, (Chrysemys Picta) In A Marsh-Fen Ecosystem, Eric S. Mcgee

Masters Theses

An ecological study of the painted turtle (Chrysemys picta) was conducted at the Fox River site in Chain O' Lakes State Park in northeastern Illinois from March to September in 1987. Findings were compared to two studies in 1986 concerning the common snapping turtle (Chelydra serpentina) and Blandings turtle (Emydoidea blandingi) also present in the area. Population densities and composition were evaluated to determine the degree of interspecific competition.

Two hundred-forty five turtles were captured in 1986 and 1987. Painted turtles comprised 75 percent of the chelonian population, while Blandings turtles and snapping turtles …

The Southern Redbelly Dace, Phoxinus Erythrogaster (Rafinesque), In Clark County, Illinois, Susan C. Darrow

Masters Theses

Population and feeding ecology of the southern redbelly dace, Phoxinus erythrogaster (Rafinesque), was studied at Rocky Branch Nature Preserve, sections 29 and 30, T12N, R12W in Clark County, Illinois. Three stations designated along the eastern portion of Rocky Branch stream were seined bimonthly July through September, 1987. The length/frequency distribution curve constructed for the 358 dace collected determined Age class 0 to be dace less than 39mm, age classes I and II were indistinguishable because of overlap of fish lengths, and age class III was determined to be dace between 69 and 74mm. Other species encountered in abundance during this …

The Effects Of Oil Well Sites On Forest Species Of Birds, Wendy J. Baker

Masters Theses

Fifty censuses were taken in 9 transects adjacent to 8 oil well openings. It was found that 2 species, the red-eyed vireo (Vireo olivaceus), and the ovenbird (Seiurus aurocapilus) were significantly affected in spatial distribution. These forest species had significantly lower numbers near the oil well site than in the forest. Two other forest species suggested the same pattern. The effect of the oil well site reaches well into the forest.

Other possible effects of the oil well sites are competition with edge species and brood parasitism by the brown-headed cowbird. Noisier sites may also affect the bird community within …

Some Potential Evolutionary Costs Associated With Paternal Care In The Water Bug Belostoma Flumineum Say, Larry Johnson

Masters Theses

Female water bugs (Belostoma flumineum) deposit eggs in a mucilaginous cement on the back of conspecific males, who then brood these eggs until hatching. Sex role reversal, in which females compete for males and males are discriminating, is predicted in this species because males provide parental care exclusively, and represent a limited resource. Presumably the advantage of this paternal behavior is increased survival of young. However, the potential exists for this egg-brooding behavior to incur evolutionary costs, and quantifying some of these costs was the thrust of this study.

One cost, a loss of polygynous opportunity, was investigated …

The Hold-Release Mechanism In The Family Crotalidae, Ronald K. Easter

Masters Theses

Strike/release vs. strike/hold feeding behavior was observed for 5 Crotalus atrox and 5 Agkistrodon piscivorous. Two sizes of warm blooded prey were offered to the rattlesnakes on alternate weeks. Cottonmouths were offered, alternately, fish or mice of equal size. Although data varied among individual subjects, cottonmouths offered fish demonstrated the strike/hold behavior significantly more often than the strike/release behavior; cottonmouths offered mice struck and released significantly more often than they struck and held. It is concluded that the strike/hold strategy in sreponse to fish is adventageous because the danger of holding such prey is minimal and the release of …

Factors Affecting The Predator-Prey Relationship Between Predaceous Diving Beetle Larvae (Dytiscus Fasciventris) And Two Anuran Tadpole Species (Bufo Americanus And Hyla Crucifer), Todd S. Campbell

Masters Theses

It has previously been demonstrated that American toad (Bufo americanus) tadpoles are more vulnerable to predation by diving beetle larvae (Dytiscus fasciventris) than are spring peeper (Hyla crucifer) tadpoles. A laboratory study was undertaken to further delineate factors that contribute to the differential vulnerability observed. Beetle larvae are more effective tadpole predators in shallow, than in deep, water and appear to prefer to adopt a "sit-and-wait" predator strategy while clinging to emergent vegetation. Depth preference experiments in the laboratory indicated that both tadpole species prefer deep areas to shallow areas irrespective of whether a …

Mating Behavior Of The Giant Waterbug Belostoma Flumineum Say, Janet E. Ruppert

Masters Theses

Sexual selection theory predicts that in the few species where males make a larger parental investment than females and limit female reproduction, females should court and compete for males (i.e. we should observe "sex-role reversal"--Trivers, 1972). These predictions were tested in the laboratory with the giant waterbug Belostoma flumineum Say (Hemiptera: Belostomatidae) . Males of this species characteristically carry and brood eggs on their dorsa, thus making a substantial parental investment.

The courtship sequence in "one male:one female" pairings began with the male "pumping" (rapidly raising and lowering his abdomen at the water's surface). This presumably attracted the female, …

Some Factors Affecting Male Back Space Availability In The Water Bug Belostoma Flumineum Say, Amanda M. Vandenburgh

Masters Theses

Various factors affecting the availability of male back space in the giant water bug, Belostoma flumineum Say, are described herein and interpreted in a manner consistent with natural selection theory. Newly emerged males are observed to breed and accept eggs sooner than newly emerged females develop an egg clutch: furthermore, newly emerged males were shown to contain motile sperm on the day of adult emergence. Newly emerged females did not contain any mature eggs until approximately six days old. It was also found that newly emerged females manufacture eggs at a linear rate of 4.8 eggs per day. Egg length …

An Ecological Investigation Of Native Grassland In Southern Lower Michigan, Kim Alan Chapman

Masters Theses

Floristic and soil data from 50 relicts and other sources were analyzed using polar ordination of species presence. Historical and early scientific accounts were interpreted from the results.

The relicts ranged from wet to dry, on either sandy or loamy soil. Alkaline lakeplain sites added a third dimension of variability. Most upland remnants were interpreted as fragments of former savanna.

Floristic composition and distribution of the remnants were determined by these factors:

1. Edaphic: away from the Prairie Peninsula, only very dry or very wet sites support prairie vegetation;

2. Phytogeographic: the farther from the Prairie Peninsula, the fewer characteristics …

Inland Seawalls In Southwestern- Michigan: A Limnological Approach, Jeroen Wagendorp

Masters Theses

This research retrospectively evaluates the development of inland lake seawalls in southwestern Michigan. The objective was to look at physically induced phenomena and human induced phenomena, to determine which was most responsible for the need, and large numbers of inland lake seawalls in this region. In addition, the role of the Department of Natural Resources in inland lake seawall development was evaluated.

The findings, obtained through questionnaires, were compared to data from seawalls installed along the eastern shore of Lake Michigan, and showed that man's activity in the littoral zone was the fundamental rationale behind the installation on inland lake …

Avoidance Learning And Memory In Largemouth Bass (Micropterus Salmoides) Fed Bufo Tadpoles, Randy John Gawlik

Masters Theses

Tadpoles of the American toad (Bufo americanus) have been shown to be distasteful to largemouth bass (Micropterus salmoides) predators who learn, on the short term, to avoid them. How long bass retain this learned avoidance of Bufo larvae is unknown so an experimental design was constructed in an attempt to answer this question.

Largemouth bass were divided into four treatment groups. Two groups were initially fed exclusively larvae of Bufo americanus (one group was fed large tadpoles, the other group fed small larvae). Similarily, the other two groups were initially fed spring peeper (Hyla crucifer …

Seasonal Lekking Behavior Of The Greater Prairie-Chicken In Illinois, Scott A. Simpson

Masters Theses

Spring behavior of prairie-chickens (Tympanuchus cupido) has been studied extensively, however there is little information on fall-winter lekking activity. Greater prairie-chickens were observed weekly on a lek from 25 September 1982 to 23 June 1983 during morning and evening hours in Jasper County, Illinois. The peak number of prairie-chicken males on the lek occurred in February although hen attendance did not occur until 10 March 1983. All spring lekking activities were higher compared to that of the fall-winter period. Fall-winter lek activity was aggression which centered on probably brief, less intense male aggression which probably establishes or maintains …

Observations On Relationships Between Limb Measurements And Mode Of Locomotion In Malaysian Turtles, Duayne Nyckel

Masters Theses

Twelve Genera (spanning three Families) of Malaysian Turtles were studied to determine whether bone lengths could be correlated to mode of locomotion. Ulna, humerus, tibia, femur, coracoid (among others) were measured and results were presented graphically. Five of the genera were observed singly in a large aquarium. Data were recorded on the amount of time each spent in different locomotor modes. Both limb length data and aquarium observations suggest that turtles can be grouped into three main locomotor habits (i.e. terrestrial walking, bottomwalking, and swimming). The terrestrial group includes the genera, Geochelone, Kinixys, and Gopherus. Bottomwalkers include …

Operant Conditioning In The Water Snake (Nerodia Sipedon), Angela R. Deitz

Masters Theses

Six subjects of Nerodia sipedon were tested for runway acquisition. Five of six subjects met criterion for runway learning, demonstrating a significant decrease over the 25 day testing period in mean latency and running times. Four subjects completed 170 trials in a T-maze to test two-choice discrimination and reversal learning. All subjects met criterion for the initial discrimination and one reversal while two subjects completed four reversals and one subject met criterion for six reversals. Results are similar or superior to those previously reported for reptiles and other non-human vertebrates.

Operant Conditioning In The Psittacine, Amazona Amazonica, Gloria J. Nadolski

Masters Theses

Two Orange-winged Amazon Parrots, (Amazona amazonica) were subjected to operant conditioning involving three tests: two-choice spatial discrimination and reversal, three-choice color discrimination and reversal, and the oddity principle. Results of the habit reversal tests were compared to those of Gossett (1968) to determine the phylogenetic ranking of the learning capabilities of psittacines. In the first two habit reversal tests, the subjects completed twenty reversals using sunflower seeds as positive reinforcements. In the oddity principle test, the parrots completed the equivalent of 20 reversals, again using sunflower seeds. Criterion was met when they completed 8 consecutive correct choices with …

Factors Influencing Reforestation Of Surface Mined Lands In Southern Illinois, Jill R. Medland

Masters Theses

Studies of surface coal mined lands have focused primarily on older lands mined prior to the enactment of reclamation legislation. Current laws will require extensive grading, soil replacement and revegetation. In order to more effectively reforest these lands, I have evaluated sites planted to woody species during the past decade.

The vegetational characteristics, as well as both avaian and small mammal populations of several reclaimed surface mined areas, differing in age and reclamation procedures, were compared. Success of planted trees ranged from 50 to 91% and survival varied with the species planted. There was no relationship between tree survival and …

Observed Changes In The Largemouth Bass Population Since Construction Of A New Pump Storage Reservoir At Charleston, Illinois, Lawrence B. Durham

Masters Theses

Lake Charleston, Illinois was electrofished to determine the status of the largemouth bass (Micropterus salmoides, Lacepede) population after its reconstruction into a pump storage reservoir. The changes observed were an increased rate of growth of the initial year class, increased average growth increment of older bass, and a more abundant bass population. Factors which may have influenced increased growth were decreased turbidity, alkalinity, and increased water level. There is a possibility the increase in water level led to an increase in terrestrial invertebrates as a food source, and increased spawning substrate and cover due to submerged terrestrial vegetation. …

Parental Foraging In Chipping Sparrows (Spizella Passerina), Dora Elisa Perez

Masters Theses

During the breeding season of 1982, the population of Chipping Sparrows ( Spizella passerina) that inhabits the Western Michigan University's campus was chosen to study the use of foliage and other foraging sites. Three pairs were selected to be observed intensively.

During the time the female is foraging and when the male is either foraging or in territorial advertisement activities both sexes choose needleleaf trees out of proportion to their availability.

It is also likely that in the later stages of caring for young, when food demands were highest, the birds become less selective and forage on needleleaf trees as …

The Paleoecology Of Carbonaceous (Algal) Material In The Middle Devonian Rockport Quarry Limestone Of The Northeastern Portion Of Michegan's Lower Peninsula, Jeffrey Dean Spruit

Masters Theses

The Rockport Quarry Limestone of the Lower Traverse Group represents a sequence of laterally contemporaneous carbonate platform sediments characterized in outcrop by four facies: (l) stromatoporoid biolithite, (2) organic-mud packstone, (3) biolithite-micrite transition, and (4) micrite. In facies (l), (2) and (3) dark brown 4-micron microspheres are found grouped or singly in wispy seams of brown carbonaceous material. Three species of filamentous blue-green algae were discovered in insoluble residues of facies (l) and (2). Numerous lamellar stromatoporoids and solitary corals occur with the carbonaceous-rich sediment in facies (l). Coalescing lenses of crinoid and bryozoan debris occur with the carbonaceous sediment …

The Effect Of Storm Sewer Drainage On An Urban Lake, Jose Ignacio Aizpurua

Masters Theses

The present study was undertaken to evaluate the impact from normal precipitation (ra in , snow) into an urbanized lake during 1978- 1980. Several stations were chosen, and various limnological parameters were investigated. Chemical analyses were used to estimate the annual load of nutrients input into the lake by the storm sewer and surface runoff. Excessive phosphorus and nitrogen loads from these sources were discharged into the lake.

Fecal coliform distribution in the lake before, during, and after several storm events was studied. In general, fecal coliform counts increased after storm events. Peak concentrations decreased markedly with distance of the …

Correlation Of Hook-And-Line Vulnerability Of Largemouth Bass (Micropterus Salmoides) With Selected Physicochemical Parameters At Ridge Lake, Dale P. Burkett

Masters Theses

Fluctuation in kilograms of largemouth bass caught per man-hour of fishing pressure (catch rate) in Ridge Lake (a 6.8ha impoundment located in Fox Ridge State Park, Coles County, Illinois) was positively correlated with dissolved oxygen concentration (r=0.7490), conductivity (r=0.7439), pH (r=0.5965), and alkalinity (r=0.7531). Negative correlations were found between largemouth bass catch rate and turbidity (r=-0.5145), as well as ammonia (r=-0.4694). No significant (p<0.05) correlations were found between catch rate and column water temperature, air temperature, barometric pressure, water level, maximum water temperature, minimum water temperature, maximum air temperature, or minimum air temperature.

Models describing the relationships of the most significant physicochemical parameters to catch rate of largemouth bass were chosen to represent the effects of environment …

The Possible Influence Of Nestbox Size On Nesting Behavior And Reproductive Success In The House Wren (Troglodytes Aedon), Mary Anne Sydlik

Masters Theses

Recent studies (Lohrl 1973i Karlsson and Nilsson 1977) have shown that there may be a relationship between nestbox size and clutch size in several passerine species. The present study was designed to determine whether nestbox size influences the clutch size and reproductive success of House Wrens (Troglodytes aedon) and to test possible cues a female might utilize to assess the size of a given nestbox. Four types of nestboxes were used in the study; they varied in floor surface from 3 inches by 3 inches to 8 inches by 8 inches. No statistically significant differences in clutch size or reproductive …

Repopulation Of Fishes In Riley Creek, Coles County, Illinois Following Nitrogen Fertilizer Pollution, Kim James Carney

Masters Theses

The repopulation of stream fishes was studied from 17 May 1979 to 25 October 1979 following a major kill (100% mortality) caused by nitrogen fertilizer pollution in Riley Creek, Coles County, Illinois. The extent of recovery was determined by comparing post-kill collections with pre-kill survey data that was collected on 25 October 1978.

Repopulation began six days after the abatement of the pollution source. It is suggested that the initial source of repopulation was from the nearest undamaged tributary. The first three reinhabitants in order of appearence were: stonerollers (Campostoma anomalum); creek chubs (Semotilus atromaculatus); and …

Comparative Reproduction Of The Red-Eared Turtle, Pseudemys Scripta Elegans, In Heated And Natural Lakes, Gary Marshal Thornhill

Masters Theses

The effect of heating on aquatic ecosystems by energy producing power plants has not been fully determined. A comparative study of the reproduction of Pseudemys scripta was conducted in heated and natural lakes in southwestern Illinois from 30 March to 10 July, 1979. Lakes used were the same as those used for comparative growth studies of P. scripta by another researcher. Lake Baldwin (heated) has had a reduction in vegetation since that researcher's work. Temperatures were taken of air, water surface, and one meter deep.

Turtles were caught by hand, trammel nets, and in carp-baited hoop nets. Captured turtles were …

Evaluation Of Potential Wild Turkey Habitat In Eastern Illinois, Cara B. Daugherty

Masters Theses

Reestablishment of the wild turkey has been successful in the southern part of Illinois where large established tracts of woodland occur. However, turkeys are capable of surviving in areas with less forest cover, if food, nesting materials and protection are available. This project evaluated the potential turkey habitat of a 14-county area of eastern Illinois along the drainage of the Wabash River. Six potential release sites were selected and the habitat evaluated. In these areas, oak (Quercus spp.) and hickory (Carya spp.) were the dominant tree species. Disturbance from human populations was determined in each of …

The Distribution Of Cadmium, Chromium And Lead In Crabs, Clams And Oysters From Calcasieu Estuary, Louisiana, Fritz Jaenike

Masters Theses

In November 1978, specimens of oysters (Crassostrea virginica), clams (Rangia cuneata), crabs (Callinectes sapidus) and water and sediment samples were collected from Calcasieu Estuary, Louisiana. The concentrations of cadmium, chromium and lead were determined in the samples with an inductively coupled argon plasma direct reading emission spectrophotometer. Crab claw muscle, gill and carapace tissues were analyzed separately. Oysters and clams were separated into shell and whole soft tissue samples which were analyzed separately. The concentration order of the metals in crab carapace and in oyster shells was similar to that of the sediments, (Pb …
