Ecotypic Differentiation Of Andropogon Virginicus L. In Relation To Strip Mine Spoil Banks, Valina Kay Hurt
Ecotypic Differentiation Of Andropogon Virginicus L. In Relation To Strip Mine Spoil Banks, Valina Kay Hurt
Masters Theses & Specialist Projects
Reciprocal plantings of populations of broomsedge, taken from an abandoned strip mine and from an abandoned farm plot in south central Kentucky, on strip mine spoil and abandoned field soil resulted in patterns of populations differentiation. Clonal plantings of populations from strip mine habitats and old field development appeared equal in height and biomass when grown on old field soils in both field trials and growth chamber studies. Populations when planted in strip mine soils in field trials and controlled growth experiments. Later flowering in strip mine populations may be a key to survival strategy in the harsh microclimates of …

A Taxonomic & Physiographic Survey Of Scirpus In Kentucky With Problem Species Complex Analysis, Sally Arnold
Masters Theses & Specialist Projects
The genus Scirpus was analyzed according to species occurrence and physiographic distribution in the State of Kentucky. The morphology of three taxonomic problem complexes, Scirpus atrovirens-georgianus, Scirpus validus-acutus, and Scirpus cyperinus-eriophorum-pelius-pedicellatus was evaluated to determine whether or not their components are distinct among the Kentucky specimens. Remaining taxa were likewise evaluated and identified. A key to Scirpus in Kentucky and a taxonomic treatment are presented.

Species With Extrafloral Nectaries In A Temperate Flora (Nebraska), Kathleen H. Keeler
School of Biological Sciences: Faculty Publications
Extrafloral nectaries (EFNs) are glands on a plant, not involved in pollination, that produce solutions containing sugars (and other compounds). Long noted by morphologists, EFNs have recently been observed to be part of ant-plant mutualisms. The function of EFNs appears to be to attract aggressive insects, especially ants, which by disturbing or preying upon herbivores, reduce damage to the plant (Janzen, 1966a,b; Elias and Gelband, 1975; Keeler, 1975, 1977; Bentley, 1976, 1977a,b; Schemske, 1978; Tilman, 1978; Inouye and Taylor, 1979; Pickett ad Clark, 1979). Furthermore, they constitute an unusual plant defense against herbivores: at EFNs plants employ ants as a …
Planting Trees-Why Rather Than How, Angelo Cohn
Planting Trees-Why Rather Than How, Angelo Cohn
Journal of the Minnesota Academy of Science
Three evergreen plantings over 25 years in a private woodland are described and evaluated in terms of reforestation, economics and personal satisfaction. Credit is given to government foresters and support from the Minnesota Department of Natural Resources (DN\R) and the federal Forest Incentives Program (FIP). Changes in site preparation methods, selection of species and planting procedures are discussed as outcomes of research and field experience. Cost-benefits are assigned principally to human values reflected in family learning and enhanced appreciation of the ecosystem of rural Minnesota.

Laboulbeniales On Semiaquatic Hemiptera. Iii. Rhizopodomyces, Richard K. Benjamin
Aliso: A Journal of Systematic and Floristic Botany
Thaxter's original description of Rhizopodomyces is emended to reflect new information gained from a study of not only the type species, R. merragatae, but also of six additional species described as new, R. basifurcatus, R. californicus, R. erectus , R. geniculatus, R. mexicanus, and R. polhemusii. All of the species have been found on semiaquatic bugs of the family Hebridae (Hemiptera). The female thallus of Rhizopodomyces spp. consists of a simple, two-celled receptacle, the suprabasal cell bearing a one-celled primary appendage and giving rise usually to a single, longstalked perithecium. The male thallus initially consists of …
