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 کاملPredicting consequences of climate change for ecosystem functioning: variation across trophic levels, species and individuals
Results We found that the effect of increased temperature on population growth rates is independent of species interactions, but strongly species specific. This variation among herbivores is only partly predictable from differences in species distributions and traits, but translated into large differences in their ability to control macroalgae. Further, these species effects were amplified at w...
متن کاملBiodiversity enhances ecosystem multifunctionality across trophic levels and habitats
The importance of biodiversity for the integrated functioning of ecosystems remains unclear because most evidence comes from analyses of biodiversity's effect on individual functions. Here we show that the effects of biodiversity on ecosystem function become more important as more functions are considered. We present the first systematic investigation of biodiversity's effect on ecosystem multi...
متن کاملMercury Biomagnification between Two Trophic Levels of a Grazing Food Chain (Plankton and Planktivorous Fish) in a Fresh Water Ecosystem
Background: The Present study was carried out to track and calculate Biomagnification Factor (BMF) of total mercury (T-Hg) between two different trophic levels (i.e., plankton and a planktivorous fish) in a fresh water grazing food chain. Methods: Experimental organisms were planktonic biomass and silver carp (Hypophthalmichthys molitrix) as a planktivorous fish. Silver carp samples were obt...
متن کاملTrophic interactions among three elasmobranch species coexisting in the Oman Sea: implications for resource partitioning
In this study, trophic interactions were studied among three elasmobranches including Iago omanensis, Rhinobatos punctifer and Torpedo sinuspersici coexisting in the depth ranging from 50 to 100 meters in the Oman Sea (Sistan and Balochistan waters). A total of 238 specimens were collected using industrial bottom trawlers of ‘FERDOWS’ during spring and summer,2014 and their stomach contents wer...
