Plant Hybrid Zones And Insect Host Range Expansion, Diana Pilson
Plant Hybrid Zones And Insect Host Range Expansion, Diana Pilson
Diana Pilson Publications
The hybrid bridge hypothesis suggests that plant hybrids ‘‘bridge’’ the genetic gap between actual and potential host species, and that, for this reason, herbivorous insects are more likely to evolve an expanded host range in the presence of hybrids. While intuitively appealing, the hypothesis has two implicit assumptions: that phenotypic gaps between potential hosts limit host range, and that characters controlling host use are additively inherited in plant hybrids. Evaluation of these assumptions suggests that operation of the hybrid bridge hypothesis is relatively uncommon. In addition, the hypothesis has not been well integrated into existing theoretical and empirical work on …

Studies On The Biology Of Striga Aspera (Scrophulariaceae) In Nigeria, Emmanuel Izaka Aigbokhan
Studies On The Biology Of Striga Aspera (Scrophulariaceae) In Nigeria, Emmanuel Izaka Aigbokhan
Biological Sciences Theses & Dissertations
Studies on Striga aspera are few and little information exists on its relationship with the morphologically similar and much studied S. hermonthica. Both species are sympatric in West Africa and if they hybridize, may serve as virulent gene reservoirs for each other.
The primary focus of this study was on the biology of S. aspera in Nigeria. The research focussed on its distribution, phenology, cytology, hybridization, seed dormancy, viability and germination in relation to S. hermonthica. Related studies involving the hybrids include genetic and morphological variability, pathogenicity and the simultaneous dual infection of a maize plant by both species.

Population Biology Of Intraspecific Polyploidy In Grasses, Kathleen H. Keeler
Population Biology Of Intraspecific Polyploidy In Grasses, Kathleen H. Keeler
School of Biological Sciences: Faculty Publications
Polyploidy is the duplication of an entire nuclear genome, whether diploid or higher level (Stebbins, 1971; Thompson and Lumaret, 1992) and a frequent occurrence in plants. Stebbins (1971) estimated that 30-35% of flowering plant species are polyploid, and that many more had a polyploid event in their evolutionary history, including all members of such important families as the Magnoliaceae, Salicaceae, and Ericaceae. Goldblatt (1980) estimated 55%, but probably up to 75%, of monocotyledons had at least one polyploid event in their history, using the criterion that if the species has a base number higher than n = 13 it is …

A Study Of The Lichens At Rocky Branch Nature Preserve, Clark County, Illinois, Eric B. Grunder
Masters Theses
In 1971, a graduate student at Eastern Illinois University, James E. Wiedman, studied the lichen flora of Rocky Branch Nature Preserve, Clark County, Illinois. During his study he collected, identified, and recorded a total of 64 lichen species. Since 1971, Rocky Branch Nature Preserve has experienced a dramatic increase in use by people and a concomittant decline in the quality of lichen habitats. In order to assess the decline of suitable lichen habitats and the reduction of lichen species a second study of the lichens at Rocky Branch Nature Preserve was undertaken. As part of this study, ten habitat sites …

Fine Root Biomass Distribution And Production Along A Barrier Island Chronosequence, Mark Jeffrey Stevenson
Fine Root Biomass Distribution And Production Along A Barrier Island Chronosequence, Mark Jeffrey Stevenson
Biological Sciences Theses & Dissertations
Fine roots play an important role in community development on barrier islands. Fine roots can influence nutrient losses from the soil environment along with regulating water loss based on their distribution and concentration (Nobel et al., 1989; Gleeson and Tilman, 1990). A sequential coring method was used to determine fine root biomass and total biomass along a chronosequence of barrier island dunes and swales on the Virginia Coast Reserve - Long Term Ecological Research Site. Fine root production and the effects of nitrogen fertilization were also examined using an ingrowth core method along the chronosequence. Live fine root biomass, total …

Keys and distributional maps are provided for nine genera and 43 species of Cyperaceae documented from Nebraska (excluding Carex). Two species--Eleocharis elliptica and Fimbristylis vahlii--are newly reported for the state, while seven species attributed to the state in the Flora of the Great Plains (Great Plains Flora Association, 1986)--Eleocharis compressa, E. verrucosa, E. wolfii, E. xyridiformis, Scirpus georgianus, S. smithii, and S. torreyi--are deleted based on re-identifications, lack of specimen evidence, or specimens of doubtful provenance in the state. Notes on local systematic problems within the family are also included.

The expected catastrophic extinction of species (already under way in many places) will alter the planet’s biological diversity so profoundly that, at the known rate of extinction, it will take millions of years to recover. Yet few ecologists study extinction. Indeed, very little ecology deals with any processes that last more than a few years, involve more than a handful of species, and cover an area of more than a few hectares. The temporal, spatial and organizational scales of most ecological studies are such that one can read entire issues of major journals and see no hint of impending catastrophe. …

Introduction From The Changing Prairie: North American Grasslands, Anthony Joern, Kathleen H. Keeler
School of Biological Sciences: Faculty Publications
Preserving remaining North American grasslands requires a multiability approach. In this book, we investigate three aspects of an admittedly larger problem: (1) how we as humans perceive grasslands; (2) the ecology of grasslands, in order to define the framework within which conservation and preservation efforts must operate; and (3) conservation issues. Additional sociological, economic, philosophical, and cultural considerations will provide important additional insights to preserving and managing grasslands, but are not included here. By restricting our focus to only three issues, we feel that we can provide a basic, but appropriate, understanding of grassland ecosystems for the prairie enthusiast. This …

Population Processes, Kathleen H. Keeler, Anthony Joern
School of Biological Sciences: Faculty Publications
Within the prairies, myriad populations of plants, insects, small mammals, and other organisms form distinct levels of organization. The physical forces of weather and fire and the complex networks of species interactions control each species’s structure and dynamics and determine its abundance or rarity. Variation in population dynamics and interactions over time and space determine the distribution and abundance of species, and ultimately the composition and dynamics of entire prairie communities.
To the casual observer, plant populations on prairies may seem quite static, like museums containing a diverse collection of specimens that can be seen again and again on repeated …

Preface From The Changing Prairie: North American Grasslands, Kathleen H. Keeler, Anthony Joern
School of Biological Sciences: Faculty Publications
North American grasslands have figured prominently in our North American heritage. Prairies first provided significant barriers to westward expansion, and then offered both economic and sociological opportunity, as well as heartache, for settlers. Many artists have gained significant inspiration from the beauty as well as the harshness of this region and its biota. And because of ideal climate and soil conditions, these grasslands have provided the agricultural foundation of which much of the economic growth and stability of the United States has historically depended.
Yet many see North American prairies as beautiful only when manipulated or exploited: Green croplands or …

The Effect Of Nitrogen Fertilization On The Phenology Of Roots In A Barrier Island Sand Dune Community, Everett P. Weber
The Effect Of Nitrogen Fertilization On The Phenology Of Roots In A Barrier Island Sand Dune Community, Everett P. Weber
Biological Sciences Theses & Dissertations
Little work has been done on the phenology of root growth and senescence largely due to methodological difficulties. The application of minirhizotron technology has enabled the tracking of individual roots through an entire growing season. As a result, direct measures of turnover, root growth, and an analysis of cohorts were made. Small plots on a 36 year old dune on Hog Island, a barrier island in the Virginia Coast Reserve Long Term Ecological Research Site, were fertilized with nitrogen. Minirhizotron tubes were installed in each fertilized and control plot. Each tube was sampled monthly for nine months, March through October …
