The Natural Forest Communities Of Iowa: A Resource In Trouble, Gary Hightshoe

Iowa Science Teachers Journal

Based on the original United States Land Office survey, it has been estimated that 18 percent of the total state land area was once covered by forest. Today, less than 4 percent of the Iowa landscape remains in forest. In essence, Iowa's forest lands have a value underrated and misunderstood by most of its citizens. Threatened with exhaustion of our natural forest heritage, it is imperative that the citizens of this state awaken at last to the necessity of protecting what is left. The appreciation, conservation, restoration and wise management of our remaining forest resource must play a critical role …

Iowa's Waters And Fishes: A Century And A Half Of Change, Bruce W. Menzel

Proceedings of the Iowa Academy of Science

Settlers in Iowa found a rich and diverse fisheries resource in its creeks, rivers, and lakes. However, for nearly a century, degradation of the aquatic environments and their fishes occurred as a result of agricultural and urban development. Since the 1930's management efforts have improved the interior sport fishery resources but many nongame species have been extirpated or are imperiled in the state. Various forms of pollution and habitat alteration remain as threats to the well-being of stream and lake fishes in Iowa. The Mississippi and Missouri rivers bordering Iowa have been drastically changed by navigation improvements and other influences. …

Iowa's Avifauna: Changes In The Past And Prospects For The Future, James J. Dinsmore

Proceedings of the Iowa Academy of Science

Since the time of settlement, at least 17 species (9%) of birds have disappeared as nesters in Iowa. Nine species were lost before 1900, another two before 1950, and six since 1950. Five species have been successfully introduced into Iowa, and four of these now are abundant in the state. A number of other species have benefited from human development and have increased in numbers since settlement. An additional 29 species have populations that seem endangered or threatened and may disappear before the end of this century.

Diatoms In The Des Moines River, Ryan W. Drum

Proceedings of the Iowa Academy of Science

Diatoms were observed to be the dominant algal group in all seasons in the 860 km long Des Moines River, from April 1961 through September 1964. The 9 most abundant diatom taxa were: Diatoma vulgare, Gomphonema olivaceum, Melosira granulata, Nitzschia dissipata, N. palea, Stephanodiscus hantzschii, Synedra acus and S.ulna. Of the 60 most abundant diatom taxa in the Des Moines River, 36 are important components of diatom floras in other major United States Rivers. From over 600 samples collected year around and throughout the length of the river, 274 diatom taxa representing 38 genera were identified. No new diatom …

Iowa's Wetlands, Richard A. Bishop

Proceedings of the Iowa Academy of Science

The Wisconsin glacier created a 7.6 million acre prairie-marsh-pothole complex in north-central and northwest Iowa. Prairie marshes, valuable for wildlife habitat and water retention, have been relentlessly drained. In 1938, only about 50,000 acres of prairie marshland remained and in 1980 this had been reduced to 26,470 acres of natural marsh. Meandering rivers have been straightened, eliminating miles of river course. Only 1,637 miles are officially designated as meandered streams. While natural marshes and unchannelized streams are threatened aquatic habitats, other wetlands have actually increased. Artificial reservoirs provide 47,562 water acres and 47,700 farm ponds have been constructed. Proper public …

The Analysis Of Library Books To Use With Gifted Readers Grades Four Through Six, Judith A. Mills

Graduate Research Papers

The major purpose of this research was to determine if a list of prototype questions, structured to elicit cognitive responses at the upper levels of the Taxonomy of Educational Objectives, would be sufficiently productive when applied to the episodes in twelve books that they may elicit higher level thinking from gifted readers at the fourth through sixth grade levels.

Eighty questions were developed through the use of a mini-course entitled, "Higher Cognitive Questioning" secured from Cooperative Network Inservice Resources (CNIR), and two Gifted and Talented Workshops presented to the Marshalltown Schools by Educational Consulting Associates (ECA).

Population Trends Among Iowa's Amphibians And Reptiles, James L. Christainsen

Proceedings of the Iowa Academy of Science

Sampling conducted from 1970 to 1980 indicates that ranges of about 69% of the species and subspecies of amphibians and reptiles found in the state are receeding. Of Iowa's 76 forms, 15% are considered in danger of extinction in the state, 22% threatened with ultimate extinction if corrective action is not taken, and 32% are declining. Only 8% have shown improvement in recent years and the remaining 22% appears relatively stable. Further studies are needed to precisely determine the status of each form and outline protective strategies.

To aid in the identification of the gifted and talented, the U.S. Department of Education has defined the gifted and talented as: Those individuals identified by professionally qualified persons who, by …

Help Keep Hawks In Hawkeye Land, Steve Duecker

Iowa Science Teachers Journal

Many people have watched a hawk soar on a warm spring day. As the hawk turns lazy circles in the sky, he is riding currents of air that push him up. Not much hunting is done from this soar. Hawks are equipped with strong feet and sharp claws called talons. These are for capturing and killing their food. Their hooked beak is used to tear the food up for swallowing. Hawks have ear openings and can hear fairly well. The eyes of the hawk are about eight times more powerful than a human's and are especially built to detect movement …

Perspectives On Iowa's Declining Flora And Fauna - A Symposium, Donald R. Farrar

Proceedings of the Iowa Academy of Science

Although Iowa is rich in past and present activity of eminent biologists and natural historians, a comprehensive inventory of the state's biological resources has never been assembled. With ever increasing demands on the land and an obvious decline and loss of many habitats and species, the need for such an inventory is urgent. The biological uniqueness or rarity of a particular habitat cannot be fully evaluated without state-wide data for that habitat and the species in it.

Iowa Prairie - An Endangered Ecosystem, Daryl D. Smith

Proceedings of the Iowa Academy of Science

Prior to Euro-American settlement 85% of Iowa was occupied by prairie. Today less than 0.02% of pre-settlement prairie remains; a few small remnants are scattered across the original 30 million acres. Settlement of Iowa was rapid; most of the prairie was converted to cropland by the end of the 19th century. Since prairie preservation activities were initiated in the 1930's, a number of prairie remnants have been preserved by public and private agencies. Iowa needs to be surveyed and inventoried so that the significant remaining prairie remnants can be located and preserved. Recent prairie preservation efforts have been supplemented with …

Iowa Natural Heritage Preservation: History, Present Status, And Future Challenges, Dean M. Roosa

Proceedings of the Iowa Academy of Science

Iowa was blessed with an abundant and diverse natural heritage. The history of problems of preservation of natural areas to depict the types and diversity of original Iowa are presented in an historical framework. The history is divided into 3 eras: an era of settlement (1832-1900), an era of academic concern (1900-1950), and a contemporary era (1950-present). The contemporary era is subdivided into 3 periods: an organizational period (l 950-1965), a period of inactivity (l965-1975), and a period of renewed activity (l 975-present). Two general themes are apparent: (a) numerous plans have been formulated but never adequately implemented, and (b) …

Overtly-Reinforced Cloze Procedure Versus Conventional Instruction In The Teaching Of Selected Science Facts In The Fourth Grade, Mary Janis Johnson

Graduate Research Papers

"They just can't read the material" is an expression which can be heard in almost any teacher's lounge. Often it is a science, social studies, or mathematics teacher who is complaining about the inability of students to comprehend what is read in textbooks. Media coverage suggests that children are experiencing difficulty with all the basic skills (Howe, 1979).

Using Children's Literature To Stimulate Children's Writing, Lois Jane Auliff

Graduate Research Papers

Writing helps children use language in new ways. The process of writing brings order to unorganized thinking. It brings o a conscious level vague realizations. Because writing can make ideas more concrete, it helps learning take place. As Cook relates, "It is only by putting pencil to paper, by sorting out what we have written, that we come to grips with what we know and believe."

The Effects Of A Modified Language Experience Cloze Approach Upon The Comprehension Scores Of Seventh Grade Developmental Reading Students, Nancy Dykstra Russell

Dissertations and Theses @ UNI

This study was conducted to detennine if a modified language experience cloze approach is an effective means of teaching reading to seventh grade students. Researchers and specialists in the field have indicated that the use of the cloze procedure is a valid technique for improving comprehension for two reasons. First, cloze forces the student to manipulate the semantic and syntactic cues of the language. Second, the cloze procedure material more closely approximates the reading process than the traditional questioning fonnat used with reading materials. The language experience approach was suggested for use in teaching reading since the approach eliminates the …

Interpersonal Aggression: Assertion Of Significant Reality Hypothesis, Dwight Alan Drury

Dissertations and Theses @ UNI

Interpersonal aggression is analyzed with the use of the symbolic interactionist perspective in this thesis. The literature generally lacks such an analysis. Symbolic interactionism views individuals as active definers and constructors of a reality. Individuals gain a sense of reality and the means by which to define it through the process of being socialized into various groups. That part of reality which is most important to the individual is termed "significant reality." A major part of an individual's "significant reality" is his or her self-concept. When an individual deems his or her "significant reality" is threatened, he or she may …

Earth Sheltered Housing: An Old Concept Being Refined, Loren F. Duchman
