Wave energy drives biotic patterns beyond the surf zone: Factors influencing abundance and occurrence of mobile fauna adjacent to subtropical beaches

摘要: Abstract Management of beach ecosystems often focuses on geomorphic and socio-economic issues. Yet understanding patterns processes affecting fishes invertebrates in this dynamic inshore environment will better inform ecosystem management. We used Baited Remote Underwater Video (BRUVs) to survey fish mobile invertebrate assemblages immediately beyond the surf zone (in 5–8 m depth) across 12 beaches varying energy geomorphology, assess drivers abundance occurrence. These subtropical eastern Australia were categorised based various morphological, energy, connectivity management characteristics. Characteristics associated with wave (aspect, exposure, modal value) strongest functional groups overall. Patterns for crabs, high relative Diogenid crabs (hermit crabs) at low beaches, Matutid (moon higher beaches. Bony elasmobranchs also predominantly influenced by characteristics, but these highly variable. This habitat was richer species adjacent deeper unconsolidated habitats, especially elasmobranchs. It included target fished a juvenile nursery several Carangid species. values should be considered when actions are undertaken.
