Diffusion-enhanced spatio-temporal models for estimating spatial expansion

This paper introduces a diffusion-enhanced spatio-temporal model to quantify spatial expansion dynamics, showing it outperforms separable models in estimating expansion processes.

Dynamic structural equation models for ecosystem-based fisheries management: case studies and a practical guide

This paper introduces dynamic structural equation models (DSEM) for ecosystem-based fisheries management, presenting case studies and a workflow to guide their application in understanding and predicting ecosystem dynamics.

AI for Fisheries Science: Neural Network Tools for Forecasting, Spatial Standardization, and Policy Optimization

This paper applies neural networks to fisheries science for forecasting, spatial standardization, and policy optimization using simulated examples.

Changes in body size with age do not follow the temperature-size rule

This study examines whether temperature and oxygen affect body size and growth in fish over time, finding that temperature has a small effect that varies with modeling assumptions.

Estimating scale-dependent covariate responses using two-dimensional diffusion derived from the SPDE method

This paper introduces a covariate-diffusion method to model non-local environmental responses in species distribution models, showing it recovers non-local effects and collapses to local responses when appropriate.

'surveyjoin': A Standardized Database of Fisheries Bottom Trawl Surveys in the Northeast Pacific Ocean

The paper introduces surveyjoin, a database and R package that standardizes and integrates bottom trawl survey data from the Northeast Pacific Ocean to improve fisheries management and ecosystem assessments.
