Modeling Mutualism and Competition in Interactive Population Dynamics: How Ants and Aphids Affect Lycaenid Butterfly Ecology
… is an important and complex problem in theoretical biology and quantitative ecology. Mutualistic interactions, which are generally considered relationships in which two or more species benefit from each other's presence, play a significant role in determining population dyanmics, and are …

Population and evolutionary dynamics during microbial range expansions
… the growth of tumors and microbial biofilms. In ecology, range expansions are becoming more frequent due to environmental changes and rare long distance dispersal, often facilitated by anthropogenic activities. Simple models in theoretical ecology explain many emergent properties of range …

The Ontopolitics of Complexity: Toward Agonistic Democracy and Ecological Political Economy
… history of systems theory, cybernetics, and theoretical ecology. I critique key interlocutors in the pluralism debate within ecological economics to illustrate how conventionalized complexity has created barriers to pluralistic engagement between ecological economics and political ecology. …

Diversity, variability and persistence elements for a non-equilibrium theory of eco-evolutionary dynamics
… is the subject matter of quantitative theoretical ecology. Under the framework of structural realism, the present dissertation project has advocated for the strategy of mathematical modeling as a strategy of abstraction. The goal is to explore if a range of natural ecosystems display …

An Empirical and Theoretical Comparison of the Socio-ecological Behaviors of Captive Chimpanzees (Pan troglodytes), Bonobos (Pan paniscus), and Western Lowland Gorillas (Gorilla gorilla): Social Tolerance and Behavioral Responses to Changes in Food Quality and Distribution
… species whereas bonobos were the most tolerant. Theoretical modeling was also used to investigate the impact of changing environmental conditions on the behaviors of the three African Great Apes. Here, we hypothesized that high quality, clumped food would select for aggressive behaviors …

Wirkung von Umweltchemikalien auf Gammarus fossarum - Populationsexperimente und individuenbasiertes Reproduktionsmodell
Das Schutzziel in der Ökotoxikologie ist die Population. Untersuchungen zur Wirkung von subletalen Konzentrationen einer Umweltchemikalie auf Populationsebene, zum Beispiel mit künstlichen Fließgewässersystemen (Mikrokosmen) können aussagekräftigere Beiträge zur ökotoxikologischen Bewertung …
