Allelopathic Effects Of S. Canadensis On The Germination Of Native Prairie Plants, James David Megenhardt
Allelopathic Effects Of S. Canadensis On The Germination Of Native Prairie Plants, James David Megenhardt
Masters Theses
Solidago canadensis has become a aggressive species of North American prairie forb throughout the world and within restored prairies throughout North America, causing the loss of biodiversity within those ecosystems. While reproductive methods of wind dispersed seeds and clonal expansion through rhizomes has helped S. canadensis colonize and spread through these ecosystems, S. canadensis also releases allelopathic chemicals which may inhibit the germination and growth of competing species. What was unknown is if these same allelopathic chemicals which give S. canadensis an edge within foreign ecosystems might also explain why S. canadensis is so prolific in restored North American …
The Functional Role Of Leaf Nutrients In An Old-Field Successional Community, Kirstin I. Duffin
The Functional Role Of Leaf Nutrients In An Old-Field Successional Community, Kirstin I. Duffin
Masters Theses
In functional ecology, traits that capture aspects of plant performance are used to understand how organisms interact with their environment. Leaf nutrients are an example of a functional trait that directly links to plant metabolic processes and therefore may describe plant assemblage dynamics. Multivariate leaf nutrient analyses may be used with other functional traits to understand ecological strategies because they are a direct measure of leaf metabolic processes and can describe nuances in plant allocation patterns. In this thesis, I explored (1) whether a suite of leaf nutrients (carbon, nitrogen, phosphorus, potassium, calcium, and magnesium) was related to plant growth …
