PROFILE
Matheus De Barros
Over a two-month period, contributed to the atsa-es/fish550-2025 repository by developing forecasting labs and dynamic ecological modeling tools. Built ARIMA-based forecasting modules and MARSS-driven final reports, focusing on reproducible analysis and robust UI using R, JavaScript, and Bootstrap. Implemented state-space models, including DFA and Hidden Markov Models, to analyze zooplankton, grazer, and salmon productivity dynamics with covariates, supporting model comparison and visualization. Enhanced the web interface with CSS and interactive widgets for improved usability. Addressed workflow stability by fixing model evaluation boundaries and disabling unstable calculations, ensuring reliable results and streamlined reporting for ecological time series analysis.

May 1, 2025May 2025 monthly summary for atsa-es/fish550-2025: Delivered key modeling and UI enhancements that strengthen ecological inference, forecasting, and user experience. Implemented dynamic state-space modeling (DFA/HMM) for zooplankton and grazer dynamics with covariates and AICc-based model comparisons, advanced DLMs for salmon productivity with covariates using MARSS, and comprehensive web UI improvements for the lab project. Fixed workflow instability by disabling the H_inv_2 calculation in the analysis script, stabilizing results and pipelines. Visualizations and documentation accompany the delivered work, enabling faster interpretation and reuse.
