The system, which uses beam splitters and prisms, generates in a single recorded image of two views, the front (x, z) and the side (y, z). These 3-D views were recorded high-speed digital video cameras (in Texas by a Photron FastCam Super 10K series, in Hawaii by a Kodak Motioncorder SR-3000) at 500 frames per second.</p>
<p>For the behavioral experiments, sets of individuals were transferred into the experimental chamber (1.25 x 1.25 x 4.5 cm) at densities of 7 to 15 ind mL-1 for nauplii, and 1.5 to 3 ind mL-1 for copepodites.&nbsp; When one or more individuals&nbsp;were within the camera view the hydromechanical stimulus was triggered and a video sequence that included footage from before and after the trigger was recorded.</p>
<p>The hydromechanical stimulus:&nbsp; a 3-mm diameter inert plastic sphere was attached to a stiff rod mounted to a piezoelectric pusher (DSM LPA 100 Dynamic Structures) and positioned in the upper quarter of the optical vessel.&nbsp; A pulse trigger controlled the pusher, which displaced the sphere downward by 35 microns in 0.5 ms, returning it to its initial position 60 ms later.</p>

The Drive to Survive: Copepods vs Ichthyoplankton

The Drive to Survive: Copepods vs Ichthyoplankton
<p><em>Description from NSF award abstract:</em><br />
This study will experimentally elucidate the dynamics of predator evasion by different species and life stages of copepod responding to a model larval fish predator. The PIs will use standard and high-speed videographic and cutting-edge holographic techniques. Predator-prey interactions within planktonic communities are key to understanding how energy is transferred within complex marine food webs. Of particular interest are those between the highly numerous copepods and one of their more important predators, the ichthyoplankton (the planktonic larval stages of fishes). The larvae of most fishes are planktivorous and heavily dependent on copepods for food. In general, evasion success increases with age in copepods and decreases with the age of the fish predator. How this plays out in detail is critical in determining predatory attack outcomes and the effect these have on predator and prey survival. To address this problem, different copepod developmental stages will be tested against several levels of predator competence, and the results examined for: 1) the success or failure of attacks for different combinations of predator and prey age class; 2) the kinematics (reaction latencies and trajectory orientation) for escape attempts, successful and unsuccessful, for different age classes of copepod; 3) the hydrodynamic cues generated by different ages and attack strategies of the predator and the sensitivity of different prey stages to these cues; and 4) the success or failure of the predatory approach and attack strategies at each prey stage. The data obtained will be used to inform key issues of zooplankton population dynamics. For the prey these include: predator-evasion capabilities and importance of detection ability, reaction speed, escape speed, escape orientation, and trajectory irregularity; for the predator they are: capabilities and importance of mouth gape size, stealthiness, hydrodynamic disturbance production, and lunge kinematics.</p>

<p>For the data analysis, more than 800 escape sequences in response to the stimulus were reviewed and the copepods’ body-axis orientation just prior to the stimulus trigger was recorded, as was the direction of its subsequent escape jump.&nbsp; Initial orientation and escape direction were categorized using a simple classification system: towards the sphere or away from it, according to the angle relative to the horizontal plane.&nbsp; In a few cases, the copepod’s swim/escape direction was perpendicular to the stimulus (± 5º from horizontal), and these were excluded from the analysis (fewer than 5 % of observations).&nbsp; Results for each group (myelinate vs. amyelinate) were combined and tested using the Fisher Exact test (two-tailed) to compare swimming behavior of the two groups. Nauplii and copepodites were tested separately.&nbsp; Specific comparisons included:&nbsp; 1) swim direction prior to stimulus; 2) whether the escape direction was in the direction of the original swim (“original swim direction” vs. “reverse direction”) and 3) whether escapes were directed towards or away from the stimulus (“towards sphere” vs. “away from sphere”).</p>
