Research Article: Trophic dynamics analysis and ecosystem structure for some fish species of northern Oman Sea
In the present study, a trophic structure model for some fish species of the northern Oman Sea is developed through using mass balance modeling software, Ecopath with Ecosim (EwE). In this model, we simulated 16 functional groups spread across an area of 3998.20 km2 from 2017 to 2018. Mean trophic level in the area of the present study was 3.49. Values calculated for system omnivory and connect...

متن کاملAnalysis of Long-Term Changes in a Mediterranean Marine Ecosystem Based on Fishery Landings
Long-term analyses are necessary for understanding the processes that brought the marine ecosystems as we see today, avoiding the so-called “shifting the baseline syndrome”. In the Mediterranean Sea, structured and standardized monitoring programs of marine resources were set only in the last decades, so the analysis of changes in marine communities over longer time scale has to rely on other s...
متن کاملProducer Nutritional Quality Controls Ecosystem Trophic Structure
Trophic structure, or the distribution of biomass among producers and consumers, determines key ecosystem values, such as the abundance of infectious, harvestable or conservation target species, and the storage and cycling of carbon and nutrients. There has been much debate on what controls ecosystem trophic structure, yet the answer is still elusive. Here we show that the nutritional quality o...
متن کاملEcosystem regime shifts disrupt trophic structure.
Regime shifts between alternative stable ecosystem states are becoming commonplace due to the combined effects of local stressors and global climate change. Alternative states are characterized as substantially different in form and function from pre-disturbance states, disrupting the delivery of ecosystem services and functions. On coral reefs, regime shifts are typically characterized by a ch...
