We are studying the influence of infectious disease on population dynamics and community interactions. Our work focuses on the determinants of spatial and temporal dynamics of bacterial and fungal epidemics in Daphnia. This work relies on combination of community ecology, physical limnology, and epidemiological modeling. Current projects include:
Collaborators: Carla Cáceres (Illinois), Alan Tessier (NSF), Meghan Duffy (Georgia Tech), Marianne Huebner (Michigan State), Sally MacIntyre and Robyn Smyth (UC-Santa Barbara)
We are developing and testing new theory focused around the intersection of ecological stoichiometry and food webs. The stoichiometric approach explores the consequences of mismatches in the elemental composition of grazers and plants. It also considers how supply of resources, especially nutrients and light, can set the stage for these mismatches. Most of our work examines the ability of stoichiometric models to explain:

Publications Spencer's CV Note to Prospective Students IU Biology Faculty PageI am interested in studying aquatic food webs from the community ecology of disease perspective. By integrating field and lab experiments with mathematical models, I try to answer how trophic interactions and the quality of algal resources affect the spread of disease in lakes. Currently, I’m focusing on understanding the potential role of predators as disease spreaders through trophic cascades.
Maja's CV sljivarm@umail.iu.eduI am generally interested in the eco-evolutionary forces that shape disease dynamics. Currently, I study how the cost of disease resistance interacts with other community factors to select for more or less resistant hosts. I am also investigating how the resulting host evolution feeds back on the community. I am pursuing these interests through model development, simulation, and mesocosm experiments.

Description: Inverts compromise > 99% of all animals on Earth and are remarkably diverse. With this almost incomprehensible diversity as a backdrop, we will consider how invertebrates have managed to solve life's major problems (surviving, growing and reproducing in benign-to-hostile environments), organized around a few simple themes and guided by evolution and comparative physiology. We will also survey diversity of major invertebrate groups.
Logistics: 3 credit lecture; MWF 11:15-12:05, JH A106
Office hours: W 2-4 pm, JH 015, and by appointment
Prerequisites: An intro biology course
Course WebsiteDescription: This course will empower students to develop and analyze their own ecology-based models.
Topics include: one- and multi-species models; solving for equilibria (attractors and repellors); characterizing equilibria using stability analysis; non-linear population dynamics: bifurcations, oscillations, alternative stable states, catastrophes, chaos; environmental variability.
Pre-requisites: Introductory statistics, calculus, and programming would be helpful, but relax, I will teach you what you need to know if you have not taken such courses.
Logistics: Mondays & Wednesdays, 1:30-2:45, Myers 140
Course WebsiteThe ECOLUNCH forum is meant to bring together people at the Bloomington campus who study ecology at a variety of different levels of biological organization, from genetics to populations and community ecology to ecosystems. We typically have one (or two) people present some of their current research or research ideas, with the aim of sharing ideas and results, getting feedback from the diverse group, and thinking about ecology and our research in new and broader ways. We encourage interaction among researchers of all ecological disciplines. Recent presentations have focused on molecular, population, disease and community ecology as well as ecotoxicology. We invite researchers with diverse interests to expand our breadth.
Where: Lieber Room (Jordan Hall 132)
