Iowa's Changing Forest Resources, Steven E. Jungst, Donald R. Farrar, Michael Brandrup
Iowa's Changing Forest Resources, Steven E. Jungst, Donald R. Farrar, Michael Brandrup
Journal of the Iowa Academy of Science: JIAS
After a period of decline in area extending from the 1850s to 1974, Iowa's forest area increased between 1974 and 1990. Although the area increase is encouraging, it may be fleeting. In addition, changes in forest stand structure and forest ownership patterns along with other pressures may make it difficult to maintain healthy forest ecosystems in the future. Notes from the original land survey in Iowa coupled with information from U.S. Forest Service forest inventories make it possible to look at changes in forest area and forest tree types. Unfortunately, similar long-term data do not exist to make possible a …
Distribution And Ecology Of The Morels And False Morels Of Iowa, L. H. Tiffany, G. Knaphus, D. M. Huffman
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, …

A Literature Review And Survey Of The Status Of Iowa's Terrestrial Flora, Deborah Q. Lewis
A Literature Review And Survey Of The Status Of Iowa's Terrestrial Flora, Deborah Q. Lewis
Journal of the Iowa Academy of Science: JIAS
A survey of Iowa's floristic literature and herbarium resources indicates that while there is not uniform coverage of plant groups and regions, a great deal is known about the Iowa flora. Taxonomic and floristic studies are ongoing, despite evidence of a decreased number of researchers with expertise and interest in Iowa's flora and changing emphases in academic research. Current knowledge is sufficient for the production of an Iowa Flora, and an Iowa Flora committee to initiate this project is proposed.

Iowa's Wetlands, Present And Future With A Focus On Prairie Potholes, R. A. Bishop, J. Joens, J. Zohrer
Iowa's Wetlands, Present And Future With A Focus On Prairie Potholes, R. A. Bishop, J. Joens, J. Zohrer
Journal of the Iowa Academy of Science: JIAS
The vast prairie marsh-pothole complex that historically covered approximately 7 .6 millions acres in Iowa was reduced to less than 30,000 acres by 1980 when it was estimated that only 5,000 acres of prairie marsh and pothole habitat remained in private ownership. A bleak outlook for the future of wetlands was presented by Bishop (1981)." This outlook changed with the development of the North American Waterfowl Management Plan and the passage of two important pieces of legislation: the North American Wetlands Conservation Act and the Food Security Act of 1985. Protection of existing wetlands was afforded through the Swampbuster provision …

Iowa's Declining Flora And Fauna: A Review Of Changes Since 1980 And An Outlook For The Future, Neil P. Bernstein
Iowa's Declining Flora And Fauna: A Review Of Changes Since 1980 And An Outlook For The Future, Neil P. Bernstein
Journal of the Iowa Academy of Science: JIAS
The status of Iowa's biodiversity was first summarized at a 1980 Iowa Academy of Science (IAS) symposium that was published in The Proceedings of the Iowa Academy of Science (Vol. 88, No. 1) in 1981. The 1980 symposium was updated in a recent IAS symposium, and the proceedings from this symposium are published, for the most part, in volume 105 of this journal. Most of the authors noted some positive trends, but, overall, species declines and habitat destruction remained a concern.

Lithologic And Structural Interpretation Of Gravity Data, Northeastern Iowa, Curtiss J. Hella, Richard L. Kellogg
Lithologic And Structural Interpretation Of Gravity Data, Northeastern Iowa, Curtiss J. Hella, Richard L. Kellogg
Journal of the Iowa Academy of Science: JIAS
A gravity survey was conducted over approximately 4600 square km of northeast Iowa. It was undertaken to provide detailed gravity coverage at approximately 1.6 km intervals and to model the source of several significant gravity and magnetic anomalies. 1,460 gravity stations were occupied in the survey area. Bouguer gravity and residual gravity anomaly maps were prepared, the latter using band-pass filter and trend-surface analysis techniques. The residual maps reveal that the large oval Bouguer gravity anomaly centered beneath Decorah can be traced to the southern border of the survey. Profiles crossing this feature were prepared from the Bouguer map and …

Status Of Aquatic Vascular Plants 1n Iowa's Natural Lakes, G. S. Phillips
Status Of Aquatic Vascular Plants 1n Iowa's Natural Lakes, G. S. Phillips
Journal of the Iowa Academy of Science: JIAS
Conversion of wetlands to agricultural land during the settlement of Iowa has resulted in a significant decline in the total area of lake habitat in the state. This reduction in area, combined with the degradation of remaining sites, resulted in dramatic reductions in aquatic vascular plant populations associated with Iowa's natural lakes. While declines in plant species inhabiting fen, bog, seepage, prairie pothole, and marsh type wetlands have been extensively documented, few quantitative data exist for lake type wetlands. During the summer of 1996, a total of 86 natural lakes in Iowa were surveyed for aquatic vascular plants. Many of …

Managing Seedling Emergence Of Cuphea In Iowa, W. W. Roath
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 6.4 cm, …
Book Review - The Iowa Breeding Bird Atlas, Louis B. Best
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.
Introduction To The 1997 Symposium On Iowa's Declining Flora And Fauna, Cornelia F. Mutel
Introduction To The 1997 Symposium On Iowa's Declining Flora And Fauna, Cornelia F. Mutel
Journal of the Iowa Academy of Science: JIAS
In 1980, Iowa's biologists and ecologists gathered at the 92nd annual meeting of the Iowa Academy of Science to present a symposium on the state's declining flora and fauna. Papers were published a year later in a single issue of The Proceedings of The Iowa Academy of Science (Vol. 88, No. 1), which has since been widely cited and much used as a baseline for research efforts. The symposium was a noble undertaking, for although the highly altered composition of Iowa's presettlement ecology had been widely recognized throughout the previous century, no single publication or gathering to that date …
