Home‑range allometry in coral reef fishes: comparison to other vertebrates, methodological issues and management implications

摘要: Body size has been identified as a key driver of home-range area. Despite considerable research into allometry, the relatively high variability in this relationship among taxa means that mechanisms driving are still under debate. To date, studies have predominantly focused on terrestrial taxa, and coral reef fishes particular received little attention. We quantitatively reviewed examining home range fishes, assessed interspecific between body mass positively related (slopes 1.15–1.72), with predators having larger ranges than herbivorous species. This may be attributed to mobility lower abundance predators’ food items. Coral general, appear occupy smaller area per unit vertebrates (intercepts −0.92 0.07 versus ≥1.14). is likely linked relative metabolic costs moving through water compared air. The small their apparent reluctance cross open areas suggest reserves aimed at protecting fish species more effective if located across whole reefs, even those reefs comparatively small, rather they cover subsections contiguous reef, former less reserve boundaries.
