2005/2006 Demonstration Project Delineating Areas of Vulnerability to Algal Invasion in Hawaii using a Niche Model

...building a  "Biodiversity Information Modeling Architecture" and bridging together capabilities for mapping ecosystem functions and services.

The Pride Model development pilot project is a "proof of concept" demonstration to map an invasive macro-algae problem in Maui and Oahu. The key to the modeling approach is that it is generic and scalable between different kinds of problems, so one basic parametric approach can be used generically, throughout the system, building on that to add various behaviors that a given problem requires. The fundamental structure of this newly proposed architecture, is the state-function relationship. By segregating observable states, like temperature, landcover, rainfall, human occupation, soil properties, etc, from ecological functions, such as species suitabilities, water cleansing and nutrient recycling, primary production, food production, recreation, and other "services" that ecosystems provide, it is possible to provide scientists and policy advisors with the basic tools for exploring complex ecosystem relationships. This fundamental architecture will be designed to facilitate better communication within, and consequently outside, the informatics system, for sceince, management, and policy.

Project Purposes

The purposes of this project include:

1. Develop and demonstrate a general modelling approach to identifying areas of vulnerability to marine algal invasions.
2. Improve collaboration, sharing, and integrated use of physical and biological data to answer spatial ecological questions.
3. Improve current methods and general informatics for ecosystem management, including monitoring, assessment, and mitigation.

The specific objectives of the FY05 and FY06 (proposed) efforts are:

1. Develop a general modelling approach to mapping ecological functions, and demonstrate this capability in identifying areas of vulnerability to marine algal invasions in Hawaii.
2. Design a general informatics architecture that incorporates functional models and relates them to the data layers (measured states) that control the functional distribution.
3. Show the fundamental value of this architecture for representing and exploring ecosystem complexity, including adaptive and non-linear behaviors.

Project Deliverables

1. A niche model demonstration for forecasting and mapping ecological suitabilities and functions by criteria.
2. A prototype Hawaiian Islands regional map of model-generated locations and potential vulnerability to algal invasions.
3. Evaluation of needs to integrate the approach with PBIN informatics enterprise systems.
4. Recommendations for implementing these methods in regional or national eco-informatics systems and enterprises in the region.
