Holocene Vegetational Changes In Eastern Iowa, R. G. Baker, C. A. Chumbley, P. M. Witinok, H. K. Kim

Journal of the Iowa Academy of Science: JIAS

Pollen and plant macrofossil analysis from three sites along an east-west transect in southeastern Iowa provide evidence for Holocene vegetational development. Colo Marsh at the west end of the transect is relatively complete, with a late-glacial spruce zone ending about 11,500 yr B.P.; a deciduous forest zone from about 11,500 to 8300; a prairie zone from 8300 to 4500, and prairie with oak from 4500 to presettlement times.

Sediments from the site at the Indian Creek Nature Center, midway in the transect, date only from about 6000 to 1600 yrs B. P. This site also was dominantly prairie from 6000 …

Effects Of Lake Management On Chemical, Physical, And Phycological Characteristics Of A Hypereutrophic Reservoir, Kaye J. Surratt

Masters Theses

Lake Charleston is a 1.1 billion gallon capacity side channel reservoir which was constructed in 1982 as a public drinking water supply for the City of Charleston in Coles County, Illinois. Past studies of the lake indicated an increase in eutrophication and the capacity to support large algal populations. Recent lake management practices include copper sulfate applications as an algicide and aeration to reduce flavor and odor.

In order to assess present lake status and to evaluate the effectiveness of lake management practices, two lake sites were sampled on a weekly basis from May to October, 1989. Chemical, physical, and …

A Comparison Of Two Mesic Sand Forests In Mason County, Illinois, David Timothy Coates

Masters Theses

The present study included surveys of a four hectare section of Barkhausen Conservation Area and a two hectare forested section in the Sand Prairie-Scrub Oak Nature Preserve. This study examines the floristic composition and structure of these forests, and some of the ecological parameters that may be responsible for their existence. In this study, the number, size and species of all living and dead standing trees (above 10 cm dbh) were recorded for each quadrat. The relative dominance, relative density, importance value, average diameter, density in broad diameter classes and basal area were then calculated for each species. Nested circular …

Population And Social Biology Of Free-Ranging Dogs, Canis Familiaris, Thomas J. Daniels, Marc Bekoff

Ecology Collection

Population size and density, age structure, survivorship patterns, sex ratios, social organization of urban, rural, and feral dog (Canis familiaris) populations were examined in Cd. Juarez, Mexico (urban site) and on the Navajo reservation (rural and wild sites) between June 1983 and December 1984. Urban and rural dogs were less social than expected whereas dogs characteristically lived in packs. Seasonal variation in the structure of feral dog packs influenced by reproduction, both directly (pups born into the pack) and indirectly (pregnant females may temporarily emigrate form the pack to give birth).

The Phylogeny Of The Cercomeria (Platyhelminthes: Rhabdocoela) And General Evolutionary Principles, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The unified theory of evolution is an expansion of Darwinian theory that asserts that evolution is driven by entropic accumulation of genetic information that is constrained and organized primarily by the genealogical effects of phylogenetic history and developmental integration, and secondarily by ecological effects, or natural selection in its classical mode. Phylogenetic systematic analysis of the 8 major groups of parasitic rhabdocoelous platyhelminths permits empirical macroevolutionary evaluation of these postulates. Of the 131 characters considered, 127 are phylogenetically constrained, and 4 show evidence of 1 case of convergence each. Data from different developmental stages are phylogenetically congruent, despite differences in …

Phylogenetic Relationships Among Genera Of The Tetrabothriidae (Eucestoda), Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cladistic analysis of the generic-level relationships within the family Tetrabothriidae was conducted. A single cladogram resulted from evaluation of 28 homologous transformation series representing 41 character states. The genus Tetrabothrius was recognized as plesiomorphic followed by Chaetophallus and Trigonocotyle. The latter was considered as the sister group for the remaining tetrabothriid genera of marine mammals. Anophryocephalus, Strobilocephalus, and Priapocephalus are among the most highly derived genera and are postulated as having close evolutionary affinities. Comparisons to previous explicit hypotheses for relationships among the genera indicated the present analysis was the most efficient phylogenetic statement (consistency index = …

The Complete Birder is divided into twelve chapters that can aid both the serious birder and the beginning birder. Connor opens with a chapter entitled "The Sporting Science". In this chapter he unequivocally states outright that birding is not easy, no matter how experienced one is nor how well equipped. He does say, and I tend to agree, that "birding can be exhilarating, enlightening, evocative, or exasperating -- and often all of these at once He …

The T(11;14)(P15;Q11) In A T-Cell Acute Lymphoblastic Leukemia Cell Line Activates Multiple Transcripts, Including Ttg-1, A Gene Encoding A Potential Zinc Finger Protein, Elizabeth A. Mcguire, Richard D. Hockett, Karen M. Pollock, Marty F. Bartholdi, Stephen J. O'Brien, Stanley J. Korsmeyer

Biology Faculty Articles

Interchromosomal translocations within lymphoid neoplasms frequently involve the antigen receptor genes. We cloned the breakpoints of the t(11;14)(p15;q11) in a CD3-negative T-cell acute lymphoblastic leukemia cell line (RPMI 8402) in order to identify new genes potentially involved in T-cell neoplasia. An extensive comparison of both breakpoints and their germ line counterparts indicated that an inadvertant recombinase-mediated break at chromosome segment 11p15 recombined with the delta T-cell receptor at 14q11. The derivative 11 breakpoint resembles a coding joint in which 11p15 rather than a variable region was introduced 5' to a D_δ1D_δ2J_δ1 intermediate rearrangement. Conversely, the …

Patterns Of Species Co-Occurrence In The Antillean Bat Fauna, Donald A. Mcfarlane

WM Keck Science Faculty Papers

The bat fauna of 25 Antillean islands is presented as a species presence-absence matrix, and used to construct a large population of randomized null-model matrices by Monte-Carlo simulation techniques. Comparison of the observed data matrix with the randomized population reveals a statistically significant departure from randomness which is interpreted as evidence of community structure. The Antillean bat fauna is marked by a pattern of high species co-occurrence, with endemics dominating in the northern Antilles and undifferentiated South American taxa dominating in the southern Antilles. The 'checkerboard' distributions which have been identified in the bird populations of some tropical archipelagos are …

Formulation Of A Management Scheme For The Swordfish Fishery Of The Eastern Caribbean, Harold F. Upton

Marine Affairs Theses and Major Papers

During the 1983 season, two U.S. longline vessels initiated the first attempts at the commercial exploitation of swordfish in the Eastern Caribbean. In 1986, the number of U.S. vessels participating in the fishery surpassed 40 with landings of nearly two million pounds per season. The sudden influx of participants and technology to the region has resulted in a variety of user conflicts and associated policy issues. Major areas of concern involve the conservation of a heavily exploited resource and the distribution of benefits which accrue from resource exploitation among the resource-adjacent island states and U.S. fishing operations. This study examines …

Historical Biogeography: Geography As Evolution, Evolution As Geography, Charles H. Smith

DLPS Faculty Publications

Despite a number of advances in recent years, biogeography remains a field with a poorly developed philosophical core. As a result, its historical and ecological sides remain as isolated from one another as ever. In this essay I argue that a more unified approach to biogeographic studies will become possible only when workers realise that it is necessary to reject absolute space, "geography as handmaiden" approaches to distribution problems in favour of structuralist models compatible with both probabilistic spatial interaction and deterministic phylogenetic kinds of thinking. Pros and cons of regionalist, vicariance, and panbiogeographic approaches are weighed in this regard; …

The U.S. Household Furniture Industry: Adapting To Changing Times., Brian A. Doherty, Steven H. Bullard

Faculty Publications

The U.S. wood household furniture industry has adapted to change in many ways in recent years. The industry has grown steadily since the 1982 recession, and has been shifting to the U.S . South and Southeast. Although California has also become prominent in furniture production, many recent factors indicate geographic shifts away from the state, particularly in wood furniture production. The household furniture industry has also adapted and continues to adapt to factors which have increased the globalization of trade in all products. Foreign competition has resulted in mergers and consolidation in the U.S. household furniture industry, and has also …

Microstructure Of Nunas: Andean Popping Beans (Phaseolus Vulgaris L.), Stephen C. Spaeth, Daniel G. Debouck, Joseph Tohme, Janny Van Beem

Food Structure

Nunas, popping beans (Phaseous vulgaris L.), burst and expand when heated rapidly. Differences in seed microstructure between popping and conventional (non-popping) bean genotypes conceivably contribute to popping in nunas However, the microstructural characteristics which contribute to the popping attribute and sites of expansion have not been identified. Seeds and excised cotyledons of unpopped and popped nunas were examined using scanning electron microscopy (SEM). Protoplasts of unpopped nunas were similar to protoplasts of conventional beans. Intercellular spaces of unpopped nunas were occluded by schizogenous cell walls. The occluded form of intercellular spaces differed distinctively from the open form in popped nunas …
