Ecological Stoichiometry: What Role Does it Play in the Competition and Spatial Distribution Patterns of <i>Aedes Albopictus</i> and <i>Aedes Aegypti</i>?
<p>Ecological stoichiometry is the balance of chemical substances within animal bodies through interactions and processes within their ecosystem. Though relatively underexplored, it provides a wealth of information linking interactions across different levels of organization. Detritus is the base …

Consumer nutrient stoichiometry : patterns, homeostasis, and links with fitness.
… and often influenced by human activities. Ecological stoichiometry provides one framework for understanding and predicting these linkages. Yet, as it has been extended underlying assumptions are often not evaluated. This dissertation shows that examination of implicit and explicit …

Dietary Effects on the Stoichiometry of Growth, Regulation, and Wastes of Ozark Stream Insect Detritivores
… ecosystems. In this dissertation, I used ecological stoichiometry theory to examine effects of diet nutrient content and leaf litter type on growth, regulation, and wastes of aquatic invertebrate detritivores. I tested effects of leaf litter diet carbon:phosphorus (C:P) on growth and …

Influences of Mountainside Residential Development to Nutrient Dynamics in a Stream Network
… stream by synthesizing several important ecological concepts, including ecological stoichiometry, microbial nutrient mining, and microbe-substrate interaction. I then extended the single stream model to a stream network model and further linked the stream network model with a terrestrial …

Microbial and metazoan effects on nutrient dynamics during leaf decomposition in streams
I investigated the drivers of nutrient cycling by heterotrophic microbes during leaf decomposition in streams. My research addressed two overarching questions: 1) how do exogenous and endogenous factors interact to drive microbial nitrogen (N) cycling during organic matter decomposition in stream …

Functional traits of salt marsh plants : responses of morphology- and elemental-based traits to environmental contraints, trait-trait relationships and effects on ecosystem properties
In der vorliegenden Arbeit wurden Merkmalsausprägungen von Pflanzen als Antwort auf Umwelteinflüsse untersucht und die Anwendbarkeit dieser auf Merkmals-Umwelt Konzepte überprüft. Wechselwirkungen zwischen Merkmalen und Effekte von Merkmalen auf Ökosystemfunktionen wurden analysiert. Die Arbeit …

INFLUENCES OF DISEASE-DRIVEN AMPHIBIAN DECLINES ON ECOSYSTEM STRUCTURE AND FUNCTION IN PANAMANIAN HEADWATER STREAMS
… other animals and their food resources. I used ecological stoichiometry as a framework to assess how the sudden loss of consumer biodiversity in neotropical headwater streams affected ecosystem function. I quantified N and P excretion and C:N:P ratios of tadpoles, macroinvertebrates, and food …

The role of zooplankton in cyanobacteria bloom development in Australian reservoirs
… occupy diverse aquatic habitats and their ecological success is expected to increase under predicted future climate scenarios. Managing cyanobacteria abundance in freshwaters is therefore critical for reducing risks to human and animal health. One species that is currently undergoing range …
