Full description
This study highlights the potential deleterious indirect impacts of declining habitat quality during larval settlement in habitat specialists, which could be important in the field, given that bleaching events are becoming increasingly common.
We used five anemonefishes (Amphiprion clarkii, Amphiprion latezonatus, Amphiprion ocellaris, Amphiprion percula, and Premnas biaculeatus) and three host sea anemones (Entacmaea quadricolor, Heteractis crispa, and Heteractis magnifica) in paired-choice flume experiments to determine whether habitat naïve juveniles have the olfactory capabilities to distinguish between unbleached and bleached hosts, and how this may affect settlement decisions.
Using Atema choice flume experiments we specifically tested responses by fishes to: i) unbleached anemones versus seawater; ii) bleached anemones versus seawater; iii) unbleached versus bleached anemones of the same species; iv) unbleached anemones versus bleached of different species; and v) bleached versus bleached anemones of different species.
Reef fishes can recognize bleached habitat during settlement: sea anemone bleaching alters anemonefish host selection
