Iowa Prairie: Original Extent And Loss, Preservation And Recovery Attempts, Daryl D. Smith

Journal of the Iowa Academy of Science: JIAS

Iowa's prairie has to be assessed in the context of the pre- and post-agriculturally dominated ecosystem in which it now exists. This requires an understanding of prairies and of society's perspective of prairies. Therefore, the attitudes of people through time have to be considered; (1) those who were involved in the demise of the prairie, (2) those who helped saved the pieces of the prairie and (3) those who may be called upon to recover the prairie ecosystem.

"Hades" - A Remarkable Cave On Oldoinyo Lengai In The East African Rift Valley, Gordon J. Davies

International Journal of Speleology

Oldoinyo Lengai is the world’s only active carbonatite volcano, situated in northern Tanzania within the Eastern Rift Valley, al 2.751 degrees S, 35.902 degrees E. It forms an isolated symmetrical cone at the southern end of Lake Natron, with a summit elevation of 2,890 m (9,480 ft). Periodic eruptions of ash and lava have been recorded since about 1880, and with increasing precision during this century since 1904. In 1990 a routine expedition to monitor activity levels at the summit led to the discovery of a remarkable cave located in the crater floor, filled with numerous long delicate pale yellow …

Learning To See Analogies: A Connectionist Exploration, Douglas S. Blank

Computer Science Faculty Research and Scholarship

The goal of this dissertation is to integrate learning and analogy-making. Although learning and analogy-making both have long histories as active areas of research in cognitive science, not enough attention has been given to the ways in which they may interact. To that end, this project focuses on developing a computer program, called Analogator, that learns to make analogies by seeing examples of many different analogy problems and their solutions. That is, it learns to make analogies by analogy. This approach stands in contrast to most existing computational models of analogy in which particular analogical mechanisms are assumed a priori …

Depredation On Artificial Ground Nests By Japanese Macaques: The Unspoken Exotic In Texas, Justin G. Feild, Scott E. Henke, Justin G. Mccoy

Great Plains Wildlife Damage Control Workshop Proceedings

Japanese macaques (Macaca fuscata) are old world monkeys that were introduced to Texas in 1972, and their population has since increased to over 800 individuals. Macaques are considered to be primarily vegetarian but will opportunistically forage on a variety of food items. Therefore, the objective of this study was to determine if macaques impact the nest success of bobwhite quail (Colinus virginianus). In June 1996, 20 artificial ground nests simulating those of bobwhite quail were placed randomly in areas with and without macaques. Nests were checked at 3-day intervals for 24 days and nest success was …

Old Growth Ponderosa Pine And Western Larch Stand Structures: Influences Of Pre-1900 Fires And Fire Exclusion, United States Department Of Agriculture, Forest Service

Forestry

Presents detailed age structure for two western larch stands that historically experienced frequent fires. Compares age structures of eleven ponderosa pine and western larch stands representing a broad range of sites that had frequent fires. Interprets causal factors possibly linked to variations in stand age structures.

Forest Research In Iowa's State Parks - The Values Of Natural Diversity, Donald R. Farrar

Journal of the Iowa Academy of Science: JIAS

Approximately 3% of Iowa's forests are contained in state parks and preserves. In addition to aesthetics and recreation, these protected forests provide a vital service in the unique opportunities they provide for forest research. As intact ecosystems where natural ecological processes dominate, they provide standards by which we measure the effects of livestock pasturing, methods of timber harvest, and other manipulations of managed forests. A number of current studies and public programs emphasize the importance of natural diversity in forests. They rely on state parks and preserves to provide a measure of potential diversity for a given region of the …

Fungal Colonization Of Alfalfa Stubble Following Harvest, J. K. O'Mara, G. P. Munkvold

Journal of the Iowa Academy of Science: JIAS

Two-year-old stands of alfalfa cultivars Saranac and Vernal, planted in Central Iowa, were sampled 0, 15, and 30 days after the first harvest in 1995 to identify fungi colonizing the stubble left after harvest and evaluate the role of harvest-induced wounds as infection sites for potential crown-rotting fungi. Analysis of variance was conducted to determine if sampling date and cultivar significantly affected incidence of the fungi. All stems were infected with at least one fungal species at every sampling dare. The fungal genera most frequently isolated were Alternaria, Colletotrichum, Fusarium, Phoma, and Rhizoctonia. Fusarium acuminatum was the most frequently isolated …

Distribution And Abundance Of Prairie Plant Species In The Loess Hills, Thomas R. Rosburg

Journal of the Iowa Academy of Science: JIAS

The species composition of grassland and ecotonal communities throughout the Loess Hills was studies between 1990 and 1993. Information pertaining to the latitudinal distribution of species in the Loess Hills, the abundance of species among community types (i.e., habitats), species persistence under woody encroachment, species associations, and resource partitioning among species is provided for the majority of grassland species occurring in the Loess Hills. The most abundant species on extant prairie in the Loess Hills include Bouteloua curtipendula (side-oats grama), Schizachyrium scoparium (little bluestem), Andropogon gerardii (big bluestem), Cornus drummondii (rough-leaved dogwood), Aster ericoides (heath aster), Carex heliophila (sun-loving sedge), …

Book Review - Okoboji Wetlands. A Lesson In Natural History, Robert W. Black

Journal of the Iowa Academy of Science: JIAS

Michael Lannoo's reverent, musing history of the Okoboji region, and especially its wetlands and the Iowa Lakeside Laboratory, is a uniquely structured, well-written and wonderfully illustrated introduction to a distinct region in Iowa, a rich natural history of wetland organisms and a relatively unexplored branch of environmental ethics. Lannoo draws upon many years of experience in this region, as a student, researcher and teacher, and the wonderful resources of the Iowa Lakeside Laboratory and the Iowa Great Lakes Maritime Museum to produce a volume that educates the reader of the history and natural history of the Okoboji region and provokes …

Research Note: Records Of Thirteen Ground Beetles (Coleoptera: Carabidae) New To Iowa, Foster Forbes Purrington, Kirk Jon Larsen

Journal of the Iowa Academy of Science: JIAS

A long-term ecological research initiative in northeast Iowa tallgrass prairies to evaluate the effects of prescribed burning on prairie insects was begun in 1993. During the course of this work we discovered 13 ground beetle species (Coleoptera: Carabidae) (Table 1) not previously reported from Iowa (Bousquet and Larochelle 1993).
