Abstract (abbreviated): Waterfowl die from ingesting lead shotgun pellets deposited in the bottoms of lakes and marshes and in fields. In most instances, they die after ingesting 1 or 2 pellets, their bodies wasting away over a period of several weeks, losing from 30 to 50 percent of normal weight. No other disease produces such a consistent chronic weight loss. Less frequently, a large number of shot are ingested, an acute form of lead poisoning results, and the bird dies in good weight. More definitive diagnoses of lead toxicosis have been made from levels of lead in wing bones, in blood, and in the liver and other organs.

This publication highlights a seminal workshop on landscape ecology, which focuses on spatially heterogeneous geographic areas. Such areas can include pine barrens, regions of row crop agriculture, Mediterranean woodlands, and areas of urban and suburban elements, including human actions as responses to, and their reciprocal influences on, ecological processes. Principles of landscape ecology presented in this publication provide theoretical and empirical foundations for a variety of disciplines such as regional planning, landscape architecture, and natural resources management.

Preface: Healthy, self-sustaining river systems provide important ecological and societal goods and services upon which human life depends (Postel and Richter 2003). Concern over sustaining these services has stimulated major restoration efforts, and river and stream restoration has now become a world-wild phenomenon (Palmer et al. 2005).

Despite the increased emphasis placed on river restoration, few projects are ever evaluated to assess their performance (Alexander and Allan 2006). There is a clear need to undertake meaningful monitoring of river restoration projects, not only to provide information on the effectiveness of the restorations themselves in ecological terms, but also to provide much needed data to help establish further the science of restoration (Giller 2005).

Ecological success in a restoration project cannot be assessed in the absence of clear project objectives from the start and subsequent evaluation of their achievement (Dahm et al. 1995). The goal of the Spunky Bottoms restoration project is “to restore native plant and animal communities that were characteristic of the Illinois River floodplain and to reconnect the river to the floodplain to allow movement of aquatic organisms” (Blodgett et al., this volume). The research presented in this volume provides an overview of the baseline data that were collected at The Conservancy’s Spunky Bottoms restoration project between 1998-2003. These data are intended to form the foundation of our efforts to evaluate progress toward our restoration goal.

Part 1 of these proceedings, provides an introduction to the restoration project at Spunky Bottoms. It begins with a paper by K. Douglas Blodgett et al. that describes the background and initial goals and restoration plans for The Nature Conservancy’s floodplain restoration project at Spunky Botts. The introduction section also includes a paper by Edwin R. Hajic that explores the interrelationships among Illinois River Valley wetlands, adjacent landforms, and the geomorphic processes that shaped these areas. Part 2 provides initial data from research on the aquatic systems of the site. This section includes papers that summarize research on the initial microbial communities (Tim Kelly), nitrogen and bacterial dynamics (Michael J. Lemke et al.), insect emergence patterns (A. Maria Lemke et al.), composition of the dragonfly and damselfly (Odonate) temporal patterns (Robert Novak), and development of the fish at the site are presented in Part 3, beginning with a study by Deborah Beal that provides some data on early changes in wetland plant species composition at the site. William Sluis then evaluates transplant survival of cordgrass and lake sedge. Four papers on vertebrates conclude the terrestrial systems section including preliminary surveys of reptiles and amphibians (John K. Tucker and Chris Phillips), small mammals (Edward J. Heske et al.), wetland birds (Tharran Hobson et al.), and waterfowl populations (Michelle M. Horath and Stephen P. Havera) at the site.

As the restoration of Spunky Bottoms continues, we will continue to monitor and evaluate progress towards our goal of restoring a dynamic and diverse floodplain community at the site in the hopes that the lessons learned at Spunky Bottoms can inform other large river restoration projects around the workl."

This paper reports the faunal, phonological, and host plant data associated with a collection of about 30,000 microlepidoptera representing 954 species. Collected by the late Murray O. Glenn between 1927 and 1976 in Marshall and Putnam counties, Illinois, and donated to the Illinois Natural History Survey in 1977, this collection may represent the most complete and significant assemblage of midwestern microlepidoptera in existence(Godfrey 1978). It is rivaled perhaps only by that of the late Annette F. Braun, Cincinnati, Ohio, a collection that now resides in The Academy of Natural Sciences of Philadelphia, Pennsylvania (R.W. Hodges, pers. comm.), except for a synoptic set of specimens given to the University of Louisville (C.V. Covell, Jr., pers. comm.). A substantial amount of Glenn material is also preserved in the United States National Museum of Natural History at the Smithsonian Institution. Glenn's persistent collecting activities, coupled with his careful labeling and preparation techniques, resulted in valuable data that have application to current and future ecological and systematic research and to inventorying natural resources of Illinois. This information, therefore, is made available here to aid investigators in these and related disciplines.

Executive Summary (abbreviated): More than half of the wetlands in the conterminous United States have been destroyed, and Illinois has lost about 90% of its wetlands. In a effort to slow further loss, wetlands were protected under the federal Clean Water Act. However, the 2001 United States Supreme Court decision in Solid Waste Agency of Northern Cook County v. United States Army Corps of Engineers ruled that federal protection under the Clean Water Act does not extend to “non-navigable, isolated, intrastate” wetlands. This action has left a large but undetermined number of isolated wetlands without this protection. This report summarizes the functions of isolated wetlands and estimates the number and extent of isolated wetlands in Illinois.

The identification and treatment of chemical degradation by most existing water treatment programs has been dominated by engineering technology. The lack of tools for direct biological assessments of water resources has minimized participation of aquatic biologists. A major purpose of this publication is to provide a methodology for biologists to assume roles in monitoring, evaluating, and managing water resources. The method proposed herein provides a conceptual framework for biological monitoring, and it describes a useful tool to accomplish this goal-the Index of Biotic Integrity (IBI). The strength of the IBI is its ability to integrate information from individual, population, community, zoogeographic, and ecosystem levels into a single ecologically based index of the quality of a water resource.

Introduction (abbreviated): Entomologists engaged in taxonomic research require an in-depth knowledge of the literature on the group in question. The ever increasing volume of papers, coupled with the need to know the historical literature on which the taxonomy is based, presents a major hurdle. For many groups of insects this problem has been addressed, in part through the compilation of detailed catalogs. This is not the case for aphids, and there are no catalogs to the extensive taxonomic literature on this important group. The information in this catalog is presented in three sections. The first lists the species along with extensive annotations; the second contains over 200 references related to those species; and the third records the hosts of Cinara for which documentation can be provided.

The number of Mallards (Anas platyrhynchos) breeding in Illinois and eastern North America has increased in recent decades; however, few studies have investigated the nesting biology of Mallards outside primary production areas. Therefore, we radiomarked resident female Mallards (n = 148) in west-central Illinois during 1998–2003 to assess nesting parameters and evaluate recruitment. Mean initiation date for first nests ranged from 22 April to 6 May, and the majority (75%) of nests were initiated by 20 May. Therefore, the majority of nests were predicted to hatch by 24 June. The nesting season averaged 88 days (range: 77–103 days). The proportion of unsuccessful females that renested ranged from 50.0–85.7%, and adults were more likely to renest (75.0%) than yearlings (48.0%). Nest success ranged from 9.8–33.3% and was 19.6% overall; hen success was 28.3%. Initial brood size was 8.2 ± 0.3 ducklings, but brood size declined to 3.0 ± 0.6 ducklings by 17 days posthatch. Brood survival to 20 days was 0.759 ± 0.081, and 20-day duckling survival was 0.413 ± 0.035. Female survival during spring-summer ranged from 0.546–1.00 and averaged 0.710 ± 0.096. Likewise, estimated Mallard recruitment varied annually (range: 0.302–0.672 female ducklings/female). Assuming constant female and duckling survival, we estimated that a recruitment rate of 0.613 female ducklings/adult female was necessary to maintain a stable Mallard breeding population in west-central Illinois. Estimated Mallard reproduction and recruitment was similar to that observed in other areas of North America. Nest success and hen success approached or exceeded estimated thresholds for population stability in most years; however, hen success averaged over the study period was insufficient for local population maintenance and growth. Female survival was comparable to that observed in other studies but may have limited population growth in some years. Duckling survival was sufficient for population maintenance. Management designed to enhance hen success and brood habitat may augment Mallard recruitment in west-central Illinois.

Unionid mussels were collected from three mussel beds near the confluence of the Mississippi and Illinois rivers in 2003 to evaluate concentrations of selected elements and organic compounds in three abundant species and to preliminarily investigate the relative contribution of these waterways to observed contaminant burdens. Copper (Cu), selenium (Se), and zinc (Zn) concentrations were higher and lead (Pb) concentrations were lower in Amblema plicata collected downstream of the confluence than in those collected upstream. Mean concentrations of nickel (Ni), total mercury (Hg), methylmercury (MeHg), Pb, and Zn varied by species. Concentrations of cadmium (Cd) decreased with age in A. plicata from two of three sites. Tissue concentrations of some elements, e.g., arsenic (As), Cd, Cu, Pb, Se, and Zn, were similar to or higher than those previously reported for unionid mussels from areas of contaminated sediment. Concentrations of Cd, Cu, and Zn in A. plicata were comparable to those collected from the Mississippi River approximately 450 and 900 km upstream from our study sites (Naimo et al. 1992). Although total Hg concentrations we observed were an order of magnitude lower than in that study, MeHg concentrations were above those associated with reductions in soft tissue mass in a study of Elliptio complanata (Salazar et al. 1995). A number of polychlorinated biphenyl (PCB) congeners were detected in A. plicata tissues, with 85% of detections occurring in mussels from downstream of the confluence. Concentrations of individual PCB congeners were £33 ng/g ww and the maximum summed PCB congener concentration was 100.2 ng/g ww. Although few persistent pesticides were detected, b-hexachlorocyclohexane (HCH) was detected in each of the species collected from below the confluence of the two rivers, and in A. plicata collected above it on both the Mississippi and Illinois rivers, at a maximum concentration of 103.5 ng/g ww. Aldrin, d-HCH and dichlorodiphenyltrichloroethane (DDT) were detected in few of the specimens collected. The findings of this preliminary investigation suggest that unionid mussels from near the confluence of the Mississippi and Illinois rivers may be at risk of negative health effects of elevated exposure to certain environmental contaminants. Studies examining the health and productivity of unionid mussels from this area appear warranted.

To better inform conservation and management strategics directed at Franklin’s ground squirrel, Spermophilus franklinii, I reviewed published and unpublished accounts of the squirrel’s distribution, abundance, and principally, habitat associations. I present the body of literature on S. franklinii and include portions of original accounts to avoid potential bias from paraphrasing. A consensus of the literature indicates that S. franklinii is most frequently associated with habitat characterized by a mixture of grassy and woody vegetation, referred to as savanna-like or parkland habitat. Moreover, S. franklinii has had an affinity for this type of habitat throughout its geographic range in recent, historic, and even prehistoric times. This is in contrast to a view of the species as primarily associated with tallgrass prairie habitat. As indicated in the literature, populations of S. franklinii are subject to marked fluctuations, which probably are influenced by local disturbances in addition to regular dispersal events. In the southern part of its geographic range, S. franklinii is currently limited in its occurrence principally to roadside and railroad right-of-ways. In these southern regions S.franklinii is justifiably of conservation concern. I suggest that more detailed surveys for the species (such as those that have recently occurred in Illinois and Missouri) take place in Iowa and Kansas.

We conducted a 30-day acute toxicity test of zinc (Zn) shot using 6- to 8-month-old wild-type game-farm Mallards (Anas platyrhynchos), 40 of which (20 males and 20 females) were dosed with 6 No. 4 candidate shot pellets containing 98% Zn and 2% tin (Sn); the remaining 40 ducks were dosed with 6 No. 4 steel (Fe) shot and served as controls. The Zn shot resulted in high mortality, with a greater proportion of females dying than males. For the 30-day study, survival averaged 18 and 23 days for female and male Zn-dosed ducks, respectively; all Fe-dosed ducks survived to Day 30. Ataxia/paresis and other signs of intoxication were noted in a large portion of Zn-dosed ducks. For all ducks retaining 6 shot pellets, including those that survived < 30 days, shot retention, percent of the original shot weight dissolved, and dissolution rates were similar for Zn- and Fe-dosed ducks. For those ducks that retained 6 pellets and survived to Day 30, percent loss of the original shot weight and the dissolution rate were higher in Zn-dosed ducks.

Since more research has been conducted on P. ultimum and R. solani than on T. basicola, the present research was originally designed to investigate some of the environmental factors affecting the growth of Thielaviopsis and the development of the root rot caused by it. However, another fungus, Chalaropsis thielavioides Peyronel, frequently was obtained in isolations from diseased greenhouse poinsettias. Since C. thielavioides had not been reported as being a part of the poinsettia root rot complex, the author decided to investigate its importance as a pathogen on poinsettias. Numerous similarities between C. thielavioides and T. basicola were evident. The object of this work was to compare the two fungi. Prior to undertaking such a study, the pathogenicity of Chalaropsis on poinsettias had to be established. A comparison of Chalaropsis and two isolates of Thielaviopsis was made to determine the effects of environment on the growth of the fungi and the ability of the two fungi to produce disease symptoms poinsettias.

Various bass-bluegill stocking procedures employing fry or fingerlings, adult fish alone, or mixtures of adults and fingerlings have been evaluated by Serber (1949), Swingle (1951), and Smith, Kirkwood, & Hall (1955). In these studies, stocking success was measured in such terms as standing crops of young and adult fish, balance of bass and bluegills, or evidence of overpopulation of one or both species. The principal basis for evaluation of the stocking procedures at Lake Glendale was the quality of the hook-and-line fishing. Neither of the stocking procedures used in the present study was among those reported by other workers. The 1940 stocking rates for adult largemouth bass and bluegills were almost the same as the rates used by the Illinois Department of Natural Conservation when it provides adult fish for large publicly-owned waters. For this reason, the results of the present study have special significance in this state.

The ecological life history of the warmouth, Chaenobryttus gulosus (Cuvier), was studied intensively in two habitats of Central Illinois: Venard Lake, a 3.2-acre artificial impoundment stocked only with warmouths and largemouth bass, and Park Pond, and 18-acre flooded stripmine area containing a fish population of 36 species. The intensive investigations in these two areas were supplemented by observations in other habitats and by published records on warmouth habitats and populations.

The investigation of Fork Lake was originally planned to study the effect of heavy cropping upon the combination of largemouth bass and bluegills in a small artificial lake or pond. The results obtained were influenced by the unexpected spread of Potamogeton foliosus in this pond, and a proposed final fish census was rendered impossible by a washout of the dam in 1942.

      • Illinois Furbearer Distribution and Income

            Author: Mohr, C.O.
            1943;337 pages

Distributional information information and annual catch data derived from fur-takers' monthly reports are at hand for most of the trapping seasons beginning with 1929-30 and ending with 1939-40 and are here recorded, along with records of the number of licensed fur-takers and estimates of their catch. After being compared with findings of the oral survey, raw data reports were revised in such a way as to show better than heretofore how the value of the fur catch has stood from year to year. Data for the seasons of 1931-32, 1932-33 and 1933-34 were not available to the writer, and these seasons therefore could not be considered in this study.
