Resource partitioning among early colonizing Siganus luridus and native herbivorous fish in the Mediterranean: an integrated study based on gut-content analysis and stable isotope signatures
@article{Azzurro2007ResourcePA, title={Resource partitioning among early colonizing Siganus luridus and native herbivorous fish in the Mediterranean: an integrated study based on gut-content analysis and stable isotope signatures}, author={Ernesto Azzurro and Emanuela Fanelli and Edoardo Mostarda and Marcello Catra and Franco Andaloro}, journal={Journal of the Marine Biological Association of the United Kingdom}, year={2007}, volume={87}, pages={991 - 998} }
The present study attempts to give timely information on the resource partitioning between the lessepsian migrant Siganus luridus and two ecological native analogues, Sarpa salpa and Sparisoma cretense. Sampling was carried out in concomitance with the first record of Siganus luridus in Linosa and fish were caught simultaneously, allowing direct comparison of diets. Gut-contents analyses provided a snapshot of the feeding habits of the three species: Siganus luridus fed on 34 taxa of benthic…

The results suggest that sea urchins behave as facultative omnivores and feed on vegetable or mixed diets depending on the trophic status of the system, and it is unclear, however, if this modification is behavioral or the consequence of mere changes in the availability of food items.

Investigation of ecological adaptation in S. luridus and S. rivulatus showed a greater overlap in morphological variation in the novel habitat (Mediterranean Sea) compared to the native Red Sea, and stable isotopes indicated that the invading populations segregated trophic niches more starkly than in the native habitat.

These sympatric congeneric fish species displayed clear food partitioning throughout the temporal scale analysed, linked to an increase in energy requirements for reproduction, together with the differing availability of preferred prey throughout the year.

S. rivulatus was the most tolerant and adaptable species, able to settle on a large range of substrates and habitats, including rock pools, muddy harbours and sea grass beds, and has probably replaced S. salpa on the coast of Lebanon, being more competitive than the native sparid.

Feeding habits of the Lessepsian migrant Siganus luridus in the eastern Mediterranean, its new environment
- Environmental Science
- 1988
Diet overlap, on a weight basis, indicated a similar food spectrum during spring and summer which was different from that in autumn, and its position in the food web of the eastern Mediterranean ecosystem are important characteristics that have enabled the successful establishment and build-up of the population of this Lessepsian migrant in its new environment.

The Lessepsian fishes Siganus rivulatus and S. luridus are common herbivores in the eastern Mediterra- nean, where they adapted themselves to the algal resources of the new environment, and have considerably modified their diet to adapt themselves to newAlgal resources, which differ significantly from those found in the Red Sea.

Stable-isotope data suggested more varied diets for many species than implied by gut-contents data and resolved differences between fishes feeding on planktonic and benthic prey and indicated that the herbivorous fish Sarpa salpa fed on a diet substantially different from that of other fishes.
