High-Resolution Trophic Models Reveal Structure and Function of a Northeast Pacific Ecosystem
Frontiers in Marine Science, 2019 This paper examines the structure and dynamics of the marine ecosystem surrounding Haida Gwaii (an archipelago in the southeastern Gulf of Alaska). Based on previous research, a set of improved mass-balanced models was constructed in Ecopath with Ecosim (

Introduction to ecosystem based fisheries management and ecopath modelling -Winter School on Impact of Climate Change on Indian Marine Fisheries held at CMFRI, Cochin 18.1.2008 to 7.2.2008 [PDF]
, 2008 Fish populations are an integral part of marine ecosystems. Historically, fish population dynamics have been studied as single species, for example as mackerel, shrimp or sardine, and almost always in isolation from the system in which they exist.

A trophic model of the coastal fisheries ecosystem off the west coast of Sabah and Sarawak, Malaysia [PDF]
A mass-balance steady-state trophic model of the coastal fisheries ecosystem off the West Coasts of Sabah and Sarawak, Malaysia (10 - 60 m depth) was constructed using the Ecopath software. The ecosystem models were partitioned into 29 ecological/trophic

Ecological flow analysis of network collapse II: Indicators of ecosystem level vulnerability [PDF]
, 2012 Using donor-controlled, bottom-up equations to describe network collapse we systematically investigate the impact each species has on the survival or extinction of other species. Short of extinction, one can determine the integrated losses experienced by
