Construction and Interpretation of Particle Size Distribution Spectra From 19 Ecopath Models of Chinese Coastal Ecosystems

Frontiers in Marine Science, 2020
To assess the changes that fisheries have imposed on the functioning of coastal marine ecosystems in China, 19 published Ecopath models were used to construct particle size distribution (PSD) spectra.

Using trophic models to assess the impact of fishing in the Bay of Biscay and the Celtic Sea

Aquatic Living Resources, 2017
Using the Bay of Biscay and Celtic Sea area as a case study, we showed how stock-assessments and trophic models can be useful and complementary tools to quantify the fishing impacts on the whole food web and to draw related diagnoses at the scale of ...

Constructing end-to-end models using ECOPATH data [PDF]

Journal of Marine Systems, 2011
Abstract The wide availability of ECOPATH data sets provides a valuable resource for the comparative analysis of marine ecosystems. We show how to derive a bottom–up transform from the top–down ECOPATH; couple this to a simple microbial web with physical forcing; and use the end-to-end model (E2E) for scenario construction.

Dynamics of trophic structure for the epipelagic community in the western Bering Sea

Известия ТИНРО, 2014
Changes of quantitative composition and trophic structure of the nekton community in the western Bering Sea are considered for the last decades and role of pacific salmons in dynamics of trophic flows is evaluated in dependence on their abundance using ...

Climate and fishing simultaneously impact small pelagic fish in the oceans around the southernmost tip of Africa

Frontiers in Marine Science, 2022
Climate and fisheries interact, often synergistically, and may challenge marine ecosystem functioning and, ultimately, seafood provision and human wellbeing that depend on them. Holistic and integrative approaches aiming at evaluating the spatial overlap

Trophic Relationships of Aquatic Species Offer Valuable Insights Into Shallow Lake Ecosystem Recovery. [PDF]

Ecol Evol
Trophic relationships indicated a hysteretic food web response to restoration. Plankton was the primary food source for fish and invertebrates in BYD. Aquatic plants primarily contributed to the humus formation in BYD. ABSTRACT Shallow freshwater lakes are vital for ecological and climate regulation, but many are degrading. Although restoration efforts

Using ecosystem models to inform ecosystem-based fisheries management in Europe: a review of the policy landscape and related stakeholder needs

Frontiers in Marine Science, 2023
The need to implement an ecosystem-based fisheries management (EBFM) is enshrined in numerous regulations and strategies, at both global and European level.

Using Ecopath Models to Explore Differences in Ecosystem Characteristics Between an Artificial Reef and a Nearby Natural Reef on the Coast of the North Yellow Sea, China

Frontiers in Marine Science, 2022
The comparison of trophic structure and energy flow between natural and artificial reefs is imperative to evaluate whether these man-made structures work similarly to comparable natural reefs. Here, to characterize the potential difference in functioning
