Representing mediating effects and species reintroductions in Ecopath with Ecosim

Ecological Modelling, 2011
Abstract Ecosystem models play an important role in supporting ecosystem approaches to management. To improve the representation of how ecosystems work, ecosystem models should be able to represent mediating effects (e.g., habitat provision) that species provide to each other as well as species (re)introductions, both common situations that can ...

A Preliminary Study of Ecopath with Ecosim to the Shrimp Pond Ecosystem

Applied Mechanics and Materials, 2011
Marine aquaculture is an important growing worldwide industry. An ecosystem approach to study the effects of aquaculture on shrimp ponds was implemented by using a trophic mass-balance model in order to estimate the potential effects of aquaculture and, therefore, to identify the species playing a key-role in ecosystem.

Assessing biomass gains from marsh restoration in Delaware Bay using Ecopath with Ecosim

Ecological Modelling, 2011
Abstract The Delaware Bay ecosystem has been the focus of extensive habitat restoration efforts to offset finfish losses due to mortality associated with power plant water intake. As a result, a 45 km 2 or a 3% increase in total marsh area was achieved by 1996–1997 through the restoration efforts of the Public Service Enterprise Group (PSEG).

Mediation functions in Ecopath with Ecosim: handle with care

Canadian Journal of Fisheries and Aquatic Sciences, 2014
Ecosystem models are important tools for addressing complex issues such as the role of habitat in marine resource management. The Ecopath with Ecosim (EwE) software can represent several ecological processes via mediation functions, where the abundance of one group influences trophic interactions between two other groups.

Modeling the impacts of fishing regulations in a tropical Indian estuary using Ecopath with Ecosim approach

Environment, Development and Sustainability, 2021
In this study, we measured the impacts of an effective fishing regulation on the sustainability of fisheries in Zuari estuary, a tropical estuary situated along western coast of India through an Ecosim approach. Ecosystem indicators for 2016 and 2031 (for each Ecosim scenario) were measured to compare and contrast the decadal changes in the status of ...

Modeling Potential Impacts of Gas Exploitation on the Israeli Marine Ecosystem Using Ecopath with Ecosim

2022
<p>Exploration, production, extraction and transport of fossil fuels in the marine environment are accompanied by an inherent risk to the surrounding ecosystems as a result of the on-going operations or due to technical faults, accidents or geo-hazards.

Ecopath with Ecosim as a model-building toolbox: Source code capabilities, extensions, and variations

Ecological Modelling, 2016
Abstract Ecopath with Ecosim (EwE) is a widely applied food web model that is mostly known as desktop software for the Microsoft Windows platform. The freely available Microsoft .NET source code of EwE, however, provides a range of possibilities to use the model in different ways, to customize and extend the model, and to execute the model on ...

Modeling species invasions in Ecopath with Ecosim: An evaluation using Laurentian Great Lakes models

Ecological Modelling, 2012
Abstract Invasive species affect the structure and processes of ecosystems they invade. Invasive species have been particularly relevant to the Laurentian Great Lakes, where they have played a part in both historical and recent changes to Great Lakes food webs and the fisheries supported therein.

Ecosystem dynamics in Tokyo Bay with a focus on high trophic levels using Ecopath with Ecosim

Journal of Marine Science and Technology, 2016
The present study aimed to investigate ecosystem dynamics in Tokyo Bay, a semi-enclosed bay surrounded by the Tokyo metropolitan area in Japan, which is one of the largest and most populous industrialized areas in the world. The bay has been subject to eutrophication since the 1960s, and excessive increase in phytoplankton biomass has led to hypoxia ...
