Status and ecology of walleye (Sander vitreus) and sauger (Sander canadense) in the Wabash River, IndianaWeitzel, David L. January 2004 (has links)
This study has presented a comprehensive overview of the status and ecology of walleye and sauger in the Wabash River, Indiana. Populations of walleye and sauger are relatively low in numbers. Both species exhibited a trend of increased abundance with river km from the mouth of the Wabash River. Summer walleye habitat use and movements were examined in the upper Wabash River. Walleye preferred run habitat over riffle or pool habitat. Lateral position, substrate use, and mean depth appeared to be influenced by discharge. Movements were generally short and occurred within a relatively small home range of 1.7 km. The population size limits the fisheries potential for walleye and sauger in the Wabash River mainstem. The upper Wabash River supports higher abundances of these species than the middle Wabash River and may provide a focal point for future management efforts. / Department of Biology

The Wabash, priorities in conflictLines, Scott Alan January 1978 (has links)
This creative project has taken the form of a 16 millimeter color documentary film that analyzed the proposed alteration of a major natural resource in Indiana; i.e., the Wabash River. The agency responsible for studying the proposed alteration was the U.S. Army, Corps of Engineers, which was acting in response to Congressional authorization.The film analyzed the proposed alteration, known as Wabash Navigation, from the perspectives of history, ecology, economics, and philosophy; differing world views inherent in the global ecological crisis were found to exist in the values of waterway advocates and opponents.The Corps of Engineers found this particular project to be non-feasible. However, the historical and philosophical point is made that non-feasibility does not mean that efforts to promote the waterway would necessarily be dropped. Viewers are asked to analyze the issue from the various perspectives represented in the film and formulate their own opinions.

Selected population characteristics of channel catfish, Ictalurus punctatus, and flathead catfish, Pylodictis olivaris, in the lower 200 miles of the Wabash RiverWillenberg, Zachary J. January 2000 (has links)
This study describes the population characteristics of channel catfish (Ictalurus punctatus) and flathead catfish (Pylodictis olivaris) in the lower 200 miles of the Wabash River in 1998. Densities of channel and flathead catfish did not differ over the study reach for either species. Electrofishing captured twice as many channel as flathead catfish, and hoop nets captured twice as many flatheads as channel catfish. Growth rates of channel catfish were fast as compared to documented growth in other rivers in the United States, with ages ranging from 1-8. Flathead catfish growth was average when compared to that reported in other United States rivers with ages ranging from 0-7. Length-frequency analysis for both species revealed the populations were comprised of small individuals with mortality higher than expected in older fish. This study will aid in the management of the Wabash River, as historic data are limited. / Department of Biology

Fish assemblage variation in the Wabash River, Indiana : covariation with hydrology and substratesPritchett, Jennifer M. 24 July 2010 (has links)
The local substrate composition of large rivers varies with local current velocity and high flow events. We evaluated effects of hydrology on local substrate variation for 28 Wabash River sites from 2005-08, and subsequent variation in fish assemblages using multivariate analyses. Sites were 500-m in length and fish were collected by boat electrofisher. Substrate collection methods were compared by way of habitat pole, developed by Ohio River Valley Sanitation Commission (ORSANCO), and substrate grabs. We characterized hydrologic variation with the Indicators of Hydrologic Alteration (IHA) software. We determined important driving variables of fish assemblages, substrates, and hydrology with Principle Components Analysis. Temporal effects of hydrology and substrate variation on taxonomic and functional fish assemblages were determined by repeated measures ANOVA. The analyses resulted in annual variation in fish assemblage structure, substrates and hydrologic variation. Significant relationships were found for fish assemblage structure, substrate variation, and hydrologic variation. . Our Mantel tests resulted in significant concordance among hydrology, local substrate variation, and fish assemblage structure variables in years 2005, 2006, and 2008, but not in 2007. These results demonstrated that Wabash River fish assemblages respond to substrate variation and substrate
variation is controlled largely by hydrology. A comparison of substrate quantification approaches demonstrated that the habitat pole and substrate grabs are both effective ways to describe fish assemblages but the costs of grabs outweigh the cost of the pole method. / Department of Biology

Fish assemblages in the Wabash River : responses to substrate variation in field collections and artifical streamsMueller, Robert F., Jr. January 2008 (has links)
Relationships between fish assemblage composition and substrate variation is poorly understood in large rivers. Information on fishes occurrence and behavior and substrate variation were examined in field observations for the Middle Wabash River and fine scale artificial streams experiments. The results from field observations suggested strong concordance for variation in abundance of fishes with habitat variation among sites, resulting in a longitudinal river gradient as dominant in the Middle Wabash River. In addition, shifts in fish behavior within artificial stream experiments demonstrated that species-specific habitat selection behaviors were influenced by interactions within a fish assemblage. The combination of artificial stream experiments and field observations can identify fine scale trends that bioassessment surveys cannot tease apart, and highlighting the need to examine species-habitat relationships at more than one scale. / Department of Biology

Prehistoric settlement in the upper Wabash River ValleyZoll, Mitchell K. January 1993 (has links)
1989, the Archaeological Resources Management Service Ball State University conducted a reconnaissance level survey of 550 acres located within and adjacent to the Wabash River Valley in Huntington and Wabash Counties, Indiana. Additional survey was conducted in 1990 and 1991 on areas of expanded right-of-way within the original project area. The field reconnaissance located 188 archaeological sites. Twenty-one of the sites located by those surveys were subjected to archaeological testing.This study examines data from the survey and testing and presents a distribution of sites and human settlement across the study area. The study also develops a site typology which is used to address settlement pattern questions for the study area. / Department of Anthropology

Archaic settlement patterns of the Upper Wabash DrainageVerbka, Joseph M. January 1994 (has links)
The Upper Wabash Drainage over the last few years has become an area which has provided archaeologists with vital data concerning prehistoric settlement patterns. One time period which has not been well represented is the Archaic Period. Many questions have been unanswered about Archaic settlement patterns within the region. This study examines data from archaeological survey and presents a model for both Early and Late Archaic settlement within the Upper Wabash drainage. The information generated by this analysis will provide a better understanding of the Archaic period within this region. The study will also prove to be useful as a reference for future research as well as an important mechanism for resource management. / Department of Anthropology

SCAPULA system : a computerized retrieval system for archaeological data from the Upper Wabash DrainageSun, Pao-Kong January 1984 (has links)
The heart of this dissertation is the SCAPULA Information Retrieval System, used to create, maintain, and retrieve coded archaeological data for the Upper Wabash Drainage at the Archaeology Laboratory of Ball State University.Several existing archaeological data banks were surveyed and classified at first, and different file organizations, computer software and hardware were reviewed next using as a major criterion the needs of archaeologists at Ball State in order to determine the characteristics of the SCAPULA System.The encoding instructions and retrieval keywords are illustrated and listed, while the functions of the SCAPULA are introduced. With its straightforward query instructions and examples, the SCAPULA Information Retrieval System, a relational data bank, is very easy to use.The present study sought to examine the impact of victim-observer similarity, victim physical attractiveness, outcome severity and sex of respondent on responsibility attributions made toward a rape victim. Perceived attitudinal similarity, victim physical attractiveness, and outcome severity were experimentally varied. In addition this study sought to further examine sex differences, which prior research has indicated may influence how a rape victim is perceived.A modified version of Alexander's (1980) scale was used to measure the degree of responsibility attributed to the victim, to the assailant, to society and to chance in each condition. A research design was developed using two levels of each of the four factors.The experiment was conducted during regular class periods. The population consisted of 198 male and female undergraduate students. Prior to the actual experiment, Ss were randomly assigned to review an attitude questionnaire (supposedly completed by the victim), which was either similar or dissimilar to one completed previously by themselves. The attitude survey used in this study was the Important Issues Questionnaire (Novak & Lerner, 1968). The study was conducted such that Ss perceived the victim to be either like or unlike themselves in basic attitudes. Ss were then asked to view a videotape in which a sexual assault victim was interviewed. The victim was actually an actress who read a prepared script. Outcome severity was varied by the use of written vignettes and by the victim's (actress's) narration of either having suffered an attempted rape or a rape with physical injuries. Physical attractiveness was varied by the use of cosmetics and dress. Ss were tested in groups. Each group saw only one of the four videotapes. Ss were debriefed following the experiment.The study was designed to answer the following research questions:1. Would Ss make significantly different responsibility attributions toward a victim they perceived as similar to themselves than toward a victim they perceived as dissimilar to themselves?2. Would Ss make significantly different responsibility attributions toward a victim who suffered a non-severe outcome than toward a victim who suffered a severe outcome?3. Would male Ss make significantly different attributions of responsibility toward a physically attractive victim than toward a physically unattractive victim?4. Would the respondent's sex significantly affect the degree of responsibility attributed to the victim?A 2x2x2x2 multivariate analysis of variance was used to test the four research hypothesis. Significance was considered at an alpha level of .05.FindingsThe results of this study indicated that no significant difference existed for similarity, outcome severity, sex of respondent or physical attractiveness. There was however, a tendency for Ss to attribute more responsibility to the victim who had suffered a severe outcome, and also for the assailant in that condition to be assigned a harsher penalty.ConclusionPrior research in the area of rape victim culpability has offered conflicting results. The present study sought to provide clarity to the findings of previous research. Further research is needed in this area to gain a clearer understanding of factors which influence how victims of sexual assault are perceived.
