An overview of Ecopath-Ecosim-Ecospace (www.ecopath.org), a flexible and widely used ecosystem modeling framework with static, dynamic, and spatial-temporal modules.
Talk, UBC IOF Quantitative Modeling Group Seminar Series, Vancouver, BC
Background and overview of quantitative modelling work undertaken as part of my PhD research.
Talk, Salish Sea Marine Survival Project Bottom up Working Group, Victoria, BC
Our effort is first to use the spatial-temporal abilities of Ecospace to model the Strait of Georgia ecosystem. Model can read spatial-temporal data from files to drive the model using the ‘spatial temporal framework’.
Conference Proceedings, Ecopath International 35 Year Anniversary, St. Petersburg, Florida, USA
Summary of ongoing ecosystem modelling work in the Salish Sea investigating survival declines of juvenile salmon.
Workshop Proceedings, Salish Sea Marine Survival Juvenile Salmon Workshop, Victoria, BC
In a complex and open ecosystem such as the Salish Sea, studying a species without consideration of its broader environment will naturally limit the inferences and understanding that can result
Talk, Canadian Department of Fisheries and Oceans, Vancouver, BC
EM can be applied to MSP in a similar way as in marine conservation except MSP is more complex and models can be more complex. Involve people early on in: data collection, shaping and scoping the modeling framework.
Talk, EwE International Meeting, Barcelona, Spain
Although ML approaches often are designed to work with huge input datasets, the ‘fitting’ techniques include potentially useful probabilistic and optimization methods. Various techniques have been developed for in the ML world might assist especially in cases where we are fitting ‘heuristically’
Workshop Proceedings, Salish Sea Marine Survival Pinniped Impact Seminar, Vancouver, BC
Seals may be reducing harvestable biomass in the Strait of Georgia, a conclusion contrary to previous studies.
Talk, The American Fisheries Society, WA-BC Chapter Meeting, Bremerton, Washington
Ecosystem models that account for trophic interaction effects on prey mortality rates typically represent mortality rates as a sum of independent or additive component rates. This may not be valid.
