Abstract Marine organisms that enter the Mediterranean from Red Sea via Suez Canal are known as Lessepsian bioinvaders. In general, genetic studies of fishes have shown little structure between and populations. Yet notable exceptions suggest importance life-history factors may influence patterns spatial variation. this study, by sampling two invasive with different life histories (the rabbitfis...

The fish genus Siganus (Siganidae) is widely distributed in the coastal habitats of all the tropical Indo-Pacific, with 28 nominal species recognized so far, based on general morphology and coloration patterns. A mitochondrial phylogeny of 16 Siganidae species, based on the partial nucleotide sequences of the cytochome b gene, was produced. Individual haplotypes of given nominal species general...

Despite the widely accepted importance of herbivory as a determinant of reef benthic community structure, few studies have examined the relative contributions of individual species to ecosystem processes at the whole reef scale. This study quantifies the grazing impact of individual species of roving herbivorous fishes across an inner shelf fringing reef at Orpheus Island, Great Barrier Reef, A...
