Behavioral responses to predation risk in brooding female amphipods (Gammarus pseudolimnaeus)

Behavioral responses to variable predation risk in the California spiny lobster Panulirus interruptus

Shelter dwelling and gregariousness are behavioral strategies used by benthic marine organisms to reduce the risk of predator-induced mortality. For spiny lobsters, the relative and synergistic success of shelter dwelling and aggregation in reducing mortality may vary with the perceived risk of predation as well as the availability and size distribution of conspecifics and shelters. We tested h...

Behavioral Responses of Bufo Arenarum Tadpoles to Odonate Naiad Predation

—In the presence of predators, anuran tadpoles often exhibit behavioral plasticity, which in turn reduces predation risk. We evaluated indirect effects of odonate larva predation on activity of Bufo arenarum tadpoles. We reared intact and tail-damaged larvae in three different predator treatments: (1) caged predators fed tadpoles; (2) caged predators that were starved; and (3) no predators. Bot...

Behavioral Responses of Aedes albopictus to a Predator Are Correlated with Size-Dependent Risk of Predation.

The invasive container-dwelling mosquito Aedes albopictus (Skuse) shows modest behavioral responses to water-borne cues from predatory Corethrella appendiculata Grabham in North America. We investigate whether Ae. albopictus adjust their antipredatory responses to be proportional to size-dependent risk of predation. Fourth-instar Ae. albopictus attain a size refuge from C. appendiculata predati...

Predation Risk and Behavioral Life History

Female mouthbrooders adjust incubation duration to perceived risk of predation

The protection of young from predators is an important and costly component of parental care, and this investment should be adjusted to the predation risk for the offspring. Parents are known to fine-tune defence intensity to the perceived need of protection, yet little attention has been paid to individual variation in the duration of brood defence. To optimize parental investment it may be be...
