Marine mussels Brachidontes variabilis selected smaller places of refuge and enhanced byssus production upon exposure to conspecific and heterospecific cues

摘要: Abstract Refuge selection and byssus production as anti-predator responses were examined in mussels Brachidontes variabilis exposed to cues either released from damaged or intact conspecifics, heterospecific Perna viridis sympatric with B. shrimp meat novel cues. Most of the all treatment groups would seek stay a refuge for first few hours, significantly higher number conspecific group seeking refuge. More preferred smaller when they cues; other treatments did not select particular sizes Damaged elicited greatest more byssal threads being produced, which also longer thicker. Novel medium levels response, suggesting that some common injured dead individuals different taxa released, induced variabilis.
