Comparative Leaf Anatomy Of C3 And Cam Species In Oncidiinae (Maxillarieae, Orchidaceae), Samuel A. Eident
Comparative Leaf Anatomy Of C3 And Cam Species In Oncidiinae (Maxillarieae, Orchidaceae), Samuel A. Eident
Masters Theses
The subtribe Oncidiinae is a diverse group of mostly epiphytic orchids within the tribe Maxillarieae, consisting of 55 genera and 1700 species. In this group, there have been many studies examining morphological and anatomical variation as well as metabolic pathways of carbon fixation, but most have not integrated morphological and anatomical variation with a physiological aspect of inquiry. The objective of my research was to establish a suite of anatomical characteristics that can be used to distinguish between C3 and CAM species. Secondarily, I hoped to use that suite of characteristics in determining whether intermediate CAM species (those that …
Successional Changes In Leaf Nutrient Concentrations Of Woody And Herbaceous Species, Daniel Walter Kuchta
Successional Changes In Leaf Nutrient Concentrations Of Woody And Herbaceous Species, Daniel Walter Kuchta
Masters Theses
Leaf nutrient concentrations are an example of a functional trait, a trait that can be used to understand community dynamics by observing how plants interact with their environment. I explored how leaf nutrient concentrations were affected over successional time by environmental changes. The majority of prior research on functional traits focuses on either woody or herbaceous species, but not both life forms simultaneously. To address this, I also explored the successional changes to leaf nutrient concentrations, separating the plant community into woody and herbaceous species.
Healthy, mature leaves were taken from 122 taxa of woody and herbaceous species in a …
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 …
