IAN Seminar Series 2013
The goal of the IAN seminar series is to provide concise, thought-provoking ideas relating to Chesapeake Bay science and management. Short presentations (15 minutes maximum length) are immediately followed by a lunchtime discussion of the topics raised by the presenter. The discussion is summarized and is posted along with a pdf version of the seminar slides. The seminars are captured on video and posted under a Creative Commons license so they can be freely shared.

 | Science for Citizens |
Abstract Existing individual-based models of clonal plants rely on simple rules of rhizome spacing, branching angle, and branching rate to predict colonization of space by asexually reproducing ramets. These models have provided unanticipated explanations for the emergence of nonlinear patch growth observed in real populations. However, no efforts have attempted to link these models' growth or morphological parameters with environmental conditions, relying instead on constant or stochastic values. In the case of seagrasses, widespread decline has prompted managers to ask for predictive tools that might provide better understanding of the landscape-level response of these clonal plants to water quality. The Virtual Eelgrass Meadow (VEM) was created to explore how the simple rules of a modular, clonal, architecture might be linked with environmental variables such as light, temperature, and nutrients to simulate eelgrass patch dynamics. Insights from VEM simulations suggest that changes to growth rates and resource allocation in response to the physical environment provide a mechanistic explanation for the morphological plasticity of ramets, which ultimately affects patch expansion rates. | |||
