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.
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 …
