Open Source MATLAB Ecosystem Sciences Software

LAMBDA is a MatLab toolkit that performs multivariate autoregressive first-order data analysis. LAMBDA estimates community interactions using matrix algebra. The target audience is scientists with long-term ecological data.

PAMGuide is acoustic analysis software for the characterisation of the acoustic environment from sound recordings. PAMGuide can be used to produce calibrated spectrograms and statistical analyses of sound levels, and is provided in both MATLAB and R. A Tutorial on getting started with PAMGuide can be downloaded here: http://onlinelibrary.wiley.com/doi/10.1111/2041-210X.12330/suppinfo PAMGuide was published as supplementary material to the following Open Access journal article: Merchant, N.D., Fristrup, K.M., Johnson, M.P., Tyack, P.L., Witt, M.J., Blondel, P., Parks, S.E. (2015). Measuring acoustic habitats. Methods in Ecology and Evolution. http://dx.doi.org/10.1111/2041-210X.12330

ChesROMS is developing a ROMS model of the Chesapeake Bay to help in the prediction of Harmful Algal Blooms. We hope to catalyze a new method of community modeling with involvement beyond the core researchers of the ChesROMS project.

The COMBO model projects climate change impacts to coral reefs based on estimated future changes in sea-surface temperature and ocean acidification. Outputs include estimated timing of bleaching events, changes in coral reef cover, and associated changes in economic values.

The Dynamic Multispecies Metabolic Modeling (DyMMM [dĭm]) framework is a mathematical modeling tool that integrates multiple constraint-based metabolic models into a single dynamic community metabolic model. The DyMMM framework was formerly known as the DMMM framework.

This project will create a user-friendly modeling system for studying animal social aggregations. The model codifies the a new hypothesis that the animal's state, kinematics, and the group's emergent properties are dynamically linked together, with each one affecting the others. The model will be constructed using Object-Oriented MatLab.

Extended Bioaccumulation Framework (ExBAF) is a tool for assessing bioaccumulation in foodwebs. Supports several bioaccumulation models and provides tools for analysis and visualization.

The class libraries here provide infrastructure for creating simulations of low energy nuclear physics experiments, as well as some useful working programs that do simple simulations and analysis of experiments performed with magnetic spectrographs.

Image Processing/Tracking Software for off-line analysis of Field Biology Videos/Recordings.

A Matlab/GNU Octave package for dynamic box models with any number of species and compartments. Box models are useful to study the dynamics of chemicals within systems that can be described by different compartments (e.g. environmental systems).

A matlab/octave based reaction transport model describing microbially mediated isotope fractionation processes in porous media.
