Ecosystem based modeling and indication of ecological integrity in the German North Sea - Case study offshore wind parks [PDF]
, 2011 Human exploitation and use of marine and coastal areas are apparent and growing in many regions of the world. For instance, fishery, shipping, military, raw material exploitation, nature protection and the rapidly expanding offshore wind power technology

Evaluating ecosystem caps on fishery yield in the context of climate stress and predation
Ecological Applications, Volume 35, Issue 3, April 2025.Abstract Ecosystem‐based fisheries management strives to account for species interactions and ecosystem processes in natural resource management and conservation. In this context, ecosystem‐wide caps on total fishery catches have been proposed as one tool to manage multispecies fisheries with an ecosystem approach.

An overview of the marine food web in Icelandic waters using Ecopath with Ecosim
, 2018 Fishing activities have broad impacts that affect, although not exclusively, the targeted stocks. These impacts affect predators and prey of the harvested species, as well as the whole ecosystem it inhabits. Ecosystem models can be used to study the interactions that occur within a system, including those between different organisms and those between ...

African Journal of Marine Science, 2015 Ecosystem-based management of marine fisheries requires the use of simulation modelling to investigate the system-level impact of candidate fisheries management strategies. However, testing of fundamental assumptions such as system structure or process formulations is rarely done. In this study, we compare the output of three different ecosystem models

Frontiers in Marine Science, 2019 Ecological and socio-economic indicators are used as proxies for attributes of ecosystems and human communities, respectively. End-to-end models are used to predict how ecosystems will respond to alternative management actions and changing environmental ...

Sea‐Ice Retreat From the Northeast Greenland Continental Shelf Triggers a Marine Trophic Cascade
Global Change Biology, Volume 31, Issue 4, April 2025.We built a computer model of the marine food web for the continental shelf off northeast Greenland. As climate change melts sea‐ice, more light will penetrate the water column. This triggers a cascade of increasing biomass in the system from plankton to fish to whales, but a loss of habitat means fewer polar bears.

Simulating the Trophic Impacts of Fishery Policy Options on the West Florida Shelf Using Ecopath with Ecosim [PDF]
Marine and Coastal Fisheries, 2015 Abstract The recovery of several top predators in the Gulf of Mexico is likely to increase predation on and competition with other target and nontarget species, possibly causing the abundance of those species to decline. While changes are taking place at the upper trophic levels, exploitation of prey species and climate change are ...

Earth's Future, Volume 13, Issue 3, March 2025.Abstract Climate change could irreversibly modify Southern Ocean ecosystems. Marine ecosystem model (MEM) ensembles can assist policy making by projecting future changes and allowing the evaluation and assessment of alternative management approaches.

Frontiers in Marine Science, 2020 Both trophic structure and biomass flow within marine food webs are influenced by the abiotic environment and anthropogenic stressors such as fishing. The abiotic environment has a large effect on species spatial distribution patterns and productivity ...

Trophic model of the coastal fisheries ecosystem in the Gulf of Thailand [PDF]
The biomass of 40 ecological groups, the diet composition of prey and predators, production/biomass (P/B) and consumption/biomass (Q/B) ratios, and catches were used as basic input to parameterize an Ecopath model of the Gulf of Thailand.
