Modelling microplastic bioaccumulation and biomagnification potential in the Galápagos penguin ecosystem using Ecopath and Ecosim (EwE) with Ecotracer [PDF]

PLoS ONE
Bioaccumulation and biomagnification of anthropogenic particles are crucial factors in assessing microplastic impacts to marine ecosystems. Microplastic pollution poses a significant threat to iconic and often endangered species but examining their ...

Dataset and species aggregation method applied to food-web models in the Northern Ionian Sea (Central Mediterranean Sea) [PDF]

Data in Brief, 2021
The ecological roles of the species in the food web are studied through the Ecopath with Ecosim modelling approach. In this modelling approach, the food web is described by means of functional groups, each representing a species, a life stage of a ...

Beyond the Meal: Trophic Controls by Pelagic and Demersal Chondrichthyes in Two Different Mediterranean Marine Food Webs. [PDF]

Ecol Evol
Pelagic and demersal sharks played different top‐down controls in the food web. Pelagic sharks act as apex predators impacting mesoconsumers. Trophic controls patterns by demersal sharks change according to ecosystem traits. ABSTRACT Pelagic and demersal Chondrichthyes can assume different patterns of trophic controls on marine food webs, sustaining ...

Ecological indicators reveal historical regime shifts in the Black Sea ecosystem [PDF]

PeerJ, 2023
Background The Black Sea is one of the most anthropogenically disturbed marine ecosystems in the world because of introduced species, fisheries overexploitation, nutrient enrichment via pollution through river discharge, and the impacts of climate change.

Food web trophic control modulates tropical Atlantic reef ecosystems response to marine heat wave intensity and duration. [PDF]

J Anim Ecol
In this study we showed that trophic control modulates the effects of marine heatwaves (MHWs) on species biomass dynamics in a tropical and pristine Atlantic reef ecosystem. Our study provides insights into how the strength of predator–prey interactions may generate different outcomes in face of intensified and prolonged MHWs. Abstract Marine heatwaves

Facilitative interspecific interactions in marine vertebrates across scales: from individuals to ecosystems. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Facilitative interspecific interactions (FIIs) confer benefits to at least one participant without detriment to others. Although often less emphasised than antagonistic interactions in ecological studies, this review highlights the significant ecological role of FIIs across biological scales – from individual behaviours to population ...

Herring supports Northeast Pacific predators and fisheries: Insights from ecosystem modelling and management strategy evaluation. [PDF]

PLoS ONE, 2018
This paper analyzes the trophic role of Pacific herring, the potential consequences of its depletion, and the impacts of alternative herring fishing strategies on a Northeast Pacific food web in relation to precautionary, ecosystem-based management.

Ecosystem Models Can Predict the Consequences of Conservation Management Decisions. [PDF]

Ecol Lett
ABSTRACT Botelho et al. claimed that ecosystem models cannot make accurate population forecasts and should not be used in conservation management. We agree that producing accurate forecasts from ecosystem models is difficult, but assert that it has been achieved and their utility as a decision‐support tool is evident.

Couplerlib: a metadata-driven library for the integration of multiple models of higher and lower trophic level marine systems with inexact functional group matching [PDF]

Geoscientific Model Development, 2016
End-to-end modelling is a rapidly developing strategy for modelling in marine systems science and management. However, problems remain in the area of data matching and sub-model compatibility.

Global Change Asymmetrically Rewires Ecosystems. [PDF]

Ecol Lett
Understanding how global environmental change affects food webs remains a key challenge. We synthesise empirical studies to reveal a general pattern of asymmetric rewiring, where anthropogenic pressures differentially impact habitats and restructure energy pathways within food webs.
