Introduced Fungi: Some Cause Significant Plant Disease Problems, Lois H. Tiffany

Journal of the Iowa Academy of Science: JIAS

Species of the three groups of fungi characterized here on the basis of their energy source acquisition have differing potentials for becoming problem organisms following introduction as alien fungi new to Iowa. The decomposer group of fungi that obtain an energy supply by action of extracellular enzyme activity on dead plant tissues typically have perennial mycelium, are cosmopolitan in distribution, and are unlikely to become problems even if established. The second group, the mycorrhizal/lichen group are highly specific in their relationships. The mycorrhizal fungus group have a potential for being introduced as mycorrhiza already established with the roots of particular …

Iowa's Non-Native Graminoids, Thomas R. Rosburg

Journal of the Iowa Academy of Science: JIAS

Iowa's non-native graminoids include 60 species of grasses and one species of bulrush. The exotic grass species comprise a large proportion (about 31%) of the total species richness of grasses in Iowa, which are second only to the Asteraceae in terms of total species. About half of the non-native graminoids (52%) occur sporadically and form sparse, non-invasive populations, while eighteen species (about 30%) are commonly encountered in large populations throughout the state. About 60% are annuals and a large majority (89%) has been introduced from either Europe or Asia. The C3 photosynthetic pathway is prevalent, occurring in approximately two-thirds of …

Ecological Problems With Iowa's Invasive And Introduced Fishes, Neil P. Bernstein, John R. Olson

Journal of the Iowa Academy of Science: JIAS

Since the time of European settlement, at least 59 non-indigenous fish species have been introduced, reached, or moved within Iowa waters. At least 28 nonnative fish species have been introduced into, or reported from Iowa waters since settlement. Of that number, 10 are established at this time through natural reproduction. In addition, many species of native fishes have been translocated within the state, and we provide documentation for 31 of these species. Two translocated species, gizzard shad (Dorosoma cepedianum) and yellow bass (Marone mississippiensis), have had adverse impacts on Iowa's aquatic ecosystems. While many introductions are thought to be benign, …

Invasive Species In Iowa: An Introduction, James J. Dinsmore, Neil P. Bernstein

Journal of the Iowa Academy of Science: JIAS

Concern over the increasing spread of invasive species and the potential impacts of those species on native communities has been the subject of several books and hundreds of research papers in recent years. President Clinton's Executive Order on invasive species in February1999 raised national attention to this issue. Natural resource agencies have been plagued by an ever-increasing number of invasive species and now consider this issue the second most important problem (after habitat loss) in their fight to maintain some semblance of natural communities on this planet. One group of experts estimated that in the United States alone, invasives cost …

War On Weeds: Winning It For Natural Areas, Jerry E. Asher

Journal of the Iowa Academy of Science: JIAS

I am delighted to be here with you today to discuss the rapidly accelerating damage that invasive exotic plants are inflicting on natural areas in this country. This problem may seem overwhelming, but you need not despair because there are economical, realistic, and effective strategies available to meet this challenge.

There are two purposes to this presentation: to give you information you can use to convince others that invasive exotic plants are seriously harmful, and to suggest that we can win this war on invasive exotic plants if we engage enough of the right people.

An Overview And Management Plan Of Iowa's Non-Native, Invasive, Terrestrial Forbs, Deborah Q. Lewis, Richard O. Pope

Journal of the Iowa Academy of Science: JIAS

Non-native, invasive forb species have been a problem in Iowa since the earliest decades of Iowa's European settlement. The history of studies of Iowa's invasive plants began with L. H. Pammel, and these studies continue to present. Three tables cite the occurrence of many of these species in the state, with Table 1 listing 93 non-native forbs reported by Pammel, Table 2 citing ten invasive forbs of natural areas, and Table 3 adding 38 observed or potential aggressive species of Iowa's anthropogenic and natural areas.

There has been a divergence of interest and research in the management of invasive species …

More Than A Century Of Change In The Ames, Iowa Flora (1859-2000), William R. Norris, Mark P. Widrlechner, Deborah Q. Lewis, Jimmie D. Thompson, Richard O. Pope

Journal of the Iowa Academy of Science: JIAS

We compared two floras compiled in Ames, Iowa: (1) an "historic" flora based on two published floras (1871, 1890) and on 1450 herbarium voucher specimens of plants collected in Ames between 1859 and 1899, and (2) a "current" flora compiled by us during recent fieldwork (1990-2000). Our goals were to determine 1) long-term changes in composition (i.e., the proportion of native species) over time, 2) long-term changes in the abundance of individual plant species over time, and 3) the extent of gains and losses of native and non-native plant species. We found that the proportion of native species declined over …

Purple Loosestrife: History, Management, And Biological Control In Iowa, Amy P. Wiebe, John J. Obrycki

Journal of the Iowa Academy of Science: JIAS

Purple loosestrife (Lythrum salicaria) is an invasive plant species infesting wetlands in North America. Biodiversity and wetland habitat quality are reduced following purple loosestrife establishment. Several management tactics, including cultural, mechanical, and chemical controls, have had limited success in reducing the spread of purple loosestrife. Beginning in the 1990s, a biological control program has introduced several species of natural enemies from Europe that feed on purple loosestrife. Since 1994, Iowa State University has reared and released two species of beetles that feed on purple loosestrife, Galerucella calmariensis and G. pusilla. Biological control is one component of an integrated purple loosestrife …

Non-Native Amphibians And Reptiles In Iowa, James L. Christiansen

Journal of the Iowa Academy of Science: JIAS

Only a few species appear as introductions into Iowa in the last 30 years. The bullfrog, Rana catesbeiana, was systematically introduced along with fish stocked from hatcheries in the 1930s and this species continues to spread in northern Iowa where it poses a hazard to smaller frogs. Turtles sold as pets, primarily map turtles (Graptemys pseudogeographica and G. geographica) and red-eared turtles (Trachemys scripta) continue to be found in scattered ponds, usually rural, throughout the state. The eastern box turtle (Terrapene carolma) has been reported in or on the edge of most major Iowa cities even though no breeding population …

Invasive Birds In Iowa: Status, Problems, And Threats, James J. Dinsmore

Journal of the Iowa Academy of Science: JIAS

A total of 18 invasive bird species has been introduced into or have expanded their range to include Iowa. These include ten non-North American species, one North American species that has been displaced and now is established in Iowa, and seven native species that have been released to reestablish Iowa populations. Twelve of those are regularly occurring species in Iowa, and they comprise 3.0% (12 of 404) of the species known from Iowa and 5% (10 of 199) of Iowa's nesting avifauna. These percentages are similar to those found in neighboring states. Several more species are likely to become established …

Delayed Reproduction Of Translocated Red-Cockaded Woodpeckers, James R. Mccormick, Richard N. Conner, Daniel Saenz, Brent Burt

Bulletin of the Texas Ornithological Society

Twelve pairs of Red-cockaded Woodpeckers were translocated to the Angelina National Forest from October to December 1998. Five breeding pairs produced eggs or nestlings in the first breeding season, but clutch initiation was delayed. Causes may include unfamiliar habitat, lack of experience, delayed bonding, or age-related factors.

Modeling And Analysis Of Social Networks, Robert S. Renfro Ii

Theses and Dissertations

This dissertation develops new methods for the modeling and analysis of social networks. Social networks describe the complex relationships of individuals and groups in multiple overlapping contexts. Influence in a social network impacts behavior and decision making in every setting in which individuals participate. This study defines a methodology for modeling and analyzing this complex behavior using a Flow-Model representation. Multiple objectives in an influencing effort targeted at a social network are modeled using Goal Programming. Value Focused Thinking is applied to model influence and predict decisions based on the reaction of the psychological state of individuals to environmental stimuli. …
