home range allometry in coral reef fishes comparison to other vertebrates methodological issues and management implications
Oecologia, 2015Co-Authors: Kirsty L Nash, J Q Welsh, Nicholas A J Graham, David R BellwoodAbstract:Body size has been identified as a key driver of home-range area. Despite considerable research into home-range allometry, the relatively high variability in this Relationship among taxa means that the mechanisms driving this Relationship are still under debate. To date, studies have predominantly focused on terrestrial taxa, and coral reef fishes in particular have received little attention. We quantitatively reviewed studies examining home range in reef fishes, and assessed the Interspecific Relationship between body mass and home-range area. Body mass and home range are positively related in reef fishes (slopes of 1.15–1.72), with predators having larger home ranges than herbivorous species. This may be attributed to the mobility and lower abundance of predators’ food items. Coral reef fishes, and fishes in general, appear to occupy a smaller area per unit mass than terrestrial vertebrates (intercepts of −0.92 to 0.07 versus ≥1.14). This is likely linked to the relative metabolic costs of moving through water compared to air. The small home ranges of reef fishes and their apparent reluctance to cross open areas suggest that reserves aimed at protecting fish species may be more effective if located across whole reefs, even if those reefs are comparatively small, rather than if they cover subsections of contiguous reef, as home ranges in the former are less likely to cross reserve boundaries.

heteromysis sabelliphila sp nov mysida mysidae heteromysinae in facultative association with sabellids from the cape verde islands subtropical n e atlantic
Crustaceana, 2017Co-Authors: Karl J Wittma, Pete WirtzAbstract:A survey of crustaceans associated with benthic invertebrates in near-shore habitats at islands of the Cape Verde archipelago yielded a new species belonging to the genus Heteromysis , subgenus Olivemysis : H. sabelliphila sp. nov. shows a non-obligatory association with the sabellid polychaete Branchiomma nigromaculatum only during the night. This is the first documented mysid–polychaete association. The mysids apparently took particles collected by the polychaete, suggesting a kleptoparasitic Interspecific Relationship. A set of three specifically modified setae on the antennular trunk is shared by the new species with two Heteromysis species from Madeira (subtropical N.E. Atlantic), suggesting a close morphological Relationship within the subgenus Olivemysis : with H. wirtzi , commensal of the sea anemone Telmatactis cricoides , and with H. dardani , commensal of the hermit crab Dardanus calidus . A key to the Heteromysinae of the E. Atlantic and Mediterranean is given.
