Swimming and escape behavior of copepod nauplii: implications for predator-prey interactions among copepods
This study focuses on how prey behavior may affect predation risk through encounter rates and the escape success of the prey given an encounter. Temora longicornis nauplii require stronger hydrodynamic signals to elicit escape than Acartia tonsa nauplii (critical fluid deformation rates, ∆* of 2.8 to 4.0 and 1.2 to 2.5 s–1, respectively) suggesting that T. longicornis may be more susceptible to...
متن کاملThe effect of peritrich ciliates on the production of Acartia hudsonica in Long Island Sound
We studied the effects of attached peritrich ciliates on the fitness of natural populations of Acartia hudsonica (Pinhey) in Stony Brook Harbor, Long Island Sound. Ciliate infection occurred during late spring, and ciliate load (No. ind.-‘) was not related to copepod age, stage, or body size. Simulated in situ experiments conducted throughout the period of abundance of A. hudsonica showed that ...
متن کاملEscape behavior and escape circuit activation in juvenile crayfish during prey-predator interactions.
The neural systems that control escape behavior have been studied intensively in several animals, including mollusks, fish and crayfish. Surprisingly little is known, however, about the activation and the utilization of escape circuits during prey-predator interactions. To complement the physiological and anatomical studies with a necessary behavioral equivalent, we investigated encounters betw...
متن کاملEscape behavior of quantum two-particle systems with Coulomb interactions.
Quantum escapes of two particles with Coulomb interactions from a confined one-dimensional region to a semi-infinite lead are discussed by using the probability of finding all particles within the confined region, that is, the survival probability, in comparison with free particles. By taking into account the quantum effects of two identical particles, such as the Pauli exclusion principle, it ...
متن کاملEscape behavior of planktonic copepods in response to hydrodynamic disturbances: high speed video analysis
Planktonic copepods exhibit rapid escape behavior in response to hydrodynamic disturbances. Small disturbances of brief duration were produced by a piezoelectric transducer moving a small cylinder. The escape responses of free-swimming adult males and females of the copepods Acartia tonsa and A. lilljeborgii were recorded using high-speed video and quantified using computerized motion analysis ...
