All Current Publications

Foot rot is a serious contagious disease of sheep that has become a common problem in the western states in recent years. Once established in a flock, it usually remains until a consistent treatment program eliminates it. This disease must be differentiated from other foot problems if it is to be successfully treated.

The Relationship Between Physical Activity And Flexibility, Tanya Marie Schramm Oct 1998

The Relationship Between Physical Activity And Flexibility, Tanya Marie Schramm

Student Work

The purpose of this study was to determine if a relationship existed between flexibility and physical activity levels. Subjects included 128 male (n=64) and female (n=64) volunteers, 19 to 55 years of age. All subjects completed a physical activity questionnaire (which differentiated between work, sport, leisure and total physical activity) and a series of five flexibility tests. Four of the five flexibility tests were completed with the use of a goniometer which measured shoulder flexion, hip flexion, knee flexion and ankle dorsiflexion. The sit and reach test was used to assess hamstring­ lumbar flexibility. After analyzing the data ...


Rural Industry Scholarship In Agriculture : Final Report Of The Grains Research & Development Corporation For The Grain Research Committee Of Wa, John Allan Aug 1998

Rural Industry Scholarship In Agriculture : Final Report Of The Grains Research & Development Corporation For The Grain Research Committee Of Wa, John Allan

Research Reports

In 1986 the Western Australian Government established an undergraduate scholarship in agricultural science. The scholarship was introduced to attract high calibre students into agricultural science as an alternative to highly rewarded professions such as medicine, law and commerce. The State Wheat Industry Research Committee and Barley Industry Research Committee subsequently provided funding to support the scholarship. In 1992 the Grains Research and Development Corporation agreed to ongoing funding on behalf of the Grains Industry.

Taurine Status In Cats Is Not Maintained By Dietary Cysteinesulfinic Acid, S Edgar, Claudia Kirk, Q Rogers, J Morris Mar 1998

Taurine Status In Cats Is Not Maintained By Dietary Cysteinesulfinic Acid, S Edgar, Claudia Kirk, Q Rogers, J Morris

Claudia A Kirk

Endogenous synthesis of taurine by cats is limited. Putative precursors of taurine, cysteinesulfinic acid and cysteic acid, were fed to cats to determine whether they were utilized. Groups of five cats were depleted of taurine by a resin (Colestipol(R)) diet, then given 6 dietary treatments containing (g/kg diet): 0.0, 0.4, or 0.8 taurine; or 0.98 or 1.96 cysteinesulfinic acid, or 0.4 taurine + 1.0 cysteic acid for 12 wk. Plasma and whole blood taurine concentrations and body weights were measured weekly. Concentration of taurine in semitendinosus muscle was measured initially, after 2 ...


Big Reed Forest Study Sheds Light On Natural Patterns Of Growth And Mortality In Maine Woods, Nick Houtman, Unna Chokkalingam Feb 1998

Big Reed Forest Study Sheds Light On Natural Patterns Of Growth And Mortality In Maine Woods, Nick Houtman, Unna Chokkalingam

General University of Maine Publications

A new view of the constant struggle going on in the Maine woods between trees, diseases and weather has emerged from several years of painstaking research by a team of University of Maine students and faculty. Working in the Big Reed forest preserve in northern Piscataquis County, one of the largest remaining stands of old growth forest in New England, researchers have described patterns of life and death over the past 200 years with an unprecedented level of sophistication and detail.

The project was led by Unna Chokkalingam, a Ph.D. student and a native of India. Chokkalingam received her ...

Book Review - The Iowa Breeding Bird Atlas, Louis B. Best Jan 1998

Book Review - The Iowa Breeding Bird Atlas, Louis B. Best

Journal of the Iowa Academy of Science: JIAS

The Iowa Breeding Bird Atlas is the first comprehensive statewide survey of Iowa's breeding birds. Through the efforts of over 500 people, every county in the state was sampled to provide a record of the composition and distribution of the bird life in Iowa. The project entailed dividing the state into 861 atlas blocks; 83% received at least some coverage and 71 % were completed. Information known through 1995 is included in the text, although the atlas project ended in 1990.


Book Review - Birds In Iowa, Peter Wickham Jan 1998

Book Review - Birds In Iowa, Peter Wickham

Journal of the Iowa Academy of Science: JIAS

Here is a book that those who are interested in birds and their distribution in Iowa will absolutely have to possess. This volume is the successor to the book Iowa Birds, which was written by the above authors together with three others and published in 1984. It brings our understanding to the number of species of birds and their relative abundance in Iowa up-to-date. Although only twelve years elapsed between the publication of the previous volume and this one, the activity of those interested in identifying birds increased enormously during those years. In addition, their ability to identify and find ...

Distribution And Ecology Of The Morels And False Morels Of Iowa, L. H. Tiffany, G. Knaphus, D. M. Huffman Jan 1998

Distribution And Ecology Of The Morels And False Morels Of Iowa, L. H. Tiffany, G. Knaphus, D. M. Huffman

Journal of the Iowa Academy of Science: JIAS

The distribution, time of fruiting and habitats of morels and false morels in Iowa were documented during a 10 year survey (1984-1993). Distribution maps for each species also include information from published reports and from herbarium records. The true morel genus, Morchella, is represented in Iowa by five species. Three of these species, M. deliciosa, M. esculenta and M. crassipes, are sometimes interpreted as segments of one large, extremely variable species. M. semilibera and M. angusticeps also occur. M. angusticeps, a black morel, has not been previously reported from Iowa. Four false morels, two species in each of two genera ...


Managing Seedling Emergence Of Cuphea In Iowa, W. W. Roath Jan 1998

Managing Seedling Emergence Of Cuphea In Iowa, W. W. Roath

Journal of the Iowa Academy of Science: JIAS

Cuphea, a western hemisphere genus of some 260 species, has been proposed as a domestic source of medium-chain fatty acids. These fatty acids are used primarily in soap and detergent manufacture and are presently extracted from imported tropical oils or from petroleum. Considerable difficulty in obtaining consistent plant stands with direct seeding has been experienced at two Iowa locations. Trials were initiated in 1987 and continued through 1994 to test various treatments upon seedling emergence of C. laminuligera Koehne, C lanceolata Ait., and hybrid C. viscosissima Jacq. X C. lanceolata. These treatments included planting depths from 1.3 to 6 ...


Leafy Spurge (Euphorbia Esula L.) Spread In Iowa, S. C. Huerd, S. E. Taylor Jan 1998

Leafy Spurge (Euphorbia Esula L.) Spread In Iowa, S. C. Huerd, S. E. Taylor

Journal of the Iowa Academy of Science: JIAS

Leafy spurge (Euphorbia esula L.), a noxious perennial weed spreading south from the northern Great Plains into Iowa, is considered a threat to Iowa's Prairie preserves because it is an aggressive non-native plant that dominates the landscape through rapid sexual and asexual reproduction. Methods to control leafy spurge include cultural and chemical controls, and biological controls are currently being developed. In 1992 and 1993 we surveyed the extent of leafy spurge spread in Iowa and found 26 of 99 Iowa counties with leafy spurge populations. Iowa's leafy spurge populations are rapidly expanding on untilled lands such as roadsides ...
