NIMBioS Investigative Workshop

Stoichiometric Ecotoxicology

Placeholder image.

Topic: Modeling Ecotoxicological Dynamics Subject to Stoichiometric Constraints

Meeting dates: January 17-19, 2018

Location: NIMBioS at the University of Tennessee, Knoxville

Angela Peace, Mathematics and Statistics, Texas Tech Univ.
Paul Frost, Biology, Trent Univ.

Objectives: Accurately assessing the risks of contaminants requires more than an understanding of the effects of contaminants on individual organisms, but requires further understanding of complex ecological interactions, elemental cycling, and interactive effects of natural and contaminant stressors. There is increasing evidence that organisms experience interactive effects of contaminant stressors and food conditions, such as resource stoichiometry and nutrient availability. The development of ecotoxicological models over the last few decades have significantly contributed to interpreting how contaminants impact organisms and cycle through food webs. Existing modeling efforts take a variety of approaches to predict the effects of diverse chemical contaminants on organismal growth and survival; however, current models do not consider dynamical interactive effects of contaminant stressors and stoichiometric constraints, such as nutrient/light availability and food quality. This investigative workshop will provide a forum for discussions of incorporating multiple essential elements and contaminants in ecotoxicological models. The discussions and breakout sessions throughout the workshop will shed light on nutrient and chemical contaminant cycling and can ultimately help improve toxicological risk assessment protocols. The objectives for the workshop include:

  1. Discussing the importance of linking Ecological Stoichiometry with Ecotoxicology and summarizing the current state of the synthesis of these two theories
  2. Formulating a series of empirically testable and robust models of individual and population dynamics subject to stoichiometric constraints and contaminant stressors
  3. Identifying future directions for models to be used in practice for ecological risk assessments and determining areas where empirical data are lacking in order to parameterize, test, and improve the models

Stoichiometric Ecotoxicology WordPress site.   NIMBioS has created a WordPress site to facilitate group communication and information sharing for the workshop. This is an interactive tool for sharing resources and comments before, during and after the meeting. All participants will receive an official email from WordPress inviting you to join the site. You will be asked to click on the link in the email from WordPress to accept the invitation. Before the meeting, we encourage you to introduce yourself to the rest of the group by writing a post with some details about your background and what you hope to gain from the meeting. Full details on how to post, comment and upload files to the WordPress site are available at the site (

Live-stream icon. Live Stream. The Workshop will be streamed live. Note that NIMBioS Investigative Workshops involve open discussion and not necessarily a succession of talks. In addition, the schedule as posted may change during the Workshop. To view the live stream, visit Join the live chat of the event via Twitter (#ecotoxWS), displayed to the right of the live stream.

NIMBioS Investigative Workshops focus on broad topics or a set of related topics, summarizing/synthesizing the state of the art and identifying future directions. Workshops have up to 35 participants. Organizers and key invited researchers make up half the participants; the remaining participants are filled through open application from the scientific community. Open applicants selected to attend are notified by NIMBioS within two weeks of the application deadline. Investigative Workshops have the potential for leading to one or more future Working Groups. Individuals with a strong interest in the topic, including post-docs and graduate students, are encouraged to apply. If needed, NIMBioS can provide support (travel, meals, lodging) for Workshop attendees, whether from a non-profit or for-profit organization.

A goal of NIMBioS is to enhance the cadre of researchers capable of interdisciplinary efforts across mathematics and biology. As part of this goal, NIMBioS is committed to promoting diversity in all its activities. Diversity is considered in all its aspects, social and scientific, including gender, ethnicity, scientific field, career stage, geography and type of home institution. Questions regarding diversity issues should be directed to Dr. Ernest Brothers, the NIMBioS Associate Director for Diversity Enhancement ( You can read more about our Diversity Plan on our NIMBioS Policies web page. The NIMBioS building is fully handicapped accessible.
