The role of the sensory environment and predator chemical signal properties in determining NCE strength in cascading interactions on oyster reefs

The role of the sensory environment and predator chemical signal properties in determining NCE strength in cascading interactions on oyster reefs
<p><em>Extracted from the NSF award abstract:</em></p>
<p>In this project, the investigators will examine the ability of top blue crab predators to indirectly benefit the abundance of basal oyster prey by reducing the density (consumptive effects, CEs) and suppressing foraging (non-consumptive effects, NCEs) of intermediate mud crab predators. These NCEs are mediated by chemical perception of aversive cues in blue crab urine and produce a behaviorally mediated trophic cascade. Through a series of manipulative experiments, the investigators will examine how the strength of this behaviorally-mediated trophic cascade is modulated and factors that influence perceptive range such as predator diet and intake rate, and the flow environment. The investigators will also determine the chemical identity, concentration and release rate of chemical cues.</p>
<p>Identifying the quantitative and molecular aspects of aversive cues, and linking them to behavioral responses that produce trophic cascades establishes the chemical basis of risk perception by prey and how this translates into cascading ecological effects. The use of perceptive range as a framework for evaluating the effects of both chemistry and environment provides an integrated view of processes affecting chemically-mediated NCEs. The use of a water borne predator-prey signaling system to test ideas on the strength of NCEs should have broad applications.</p>

<p>Onset HOBO pressure transducers (PTs) measured absolute pressure and temperature every 30 <em>sec</em>.&nbsp; The PTs were housed in custom-made PVC stands.&nbsp; The stand’s aluminum plate prevented instrument settling during the deployment cycle and the bolt/dive-weight assembly fixed the vertical elevation of the PTs within the stand.&nbsp; The three PTs were surveyed daily with static GPS for at least two hours.&nbsp; Additionally, a GPS base station, located on the nearby fixed dock, was surveyed daily for at least eight hours to improve GPS vertical elevation accuracy during post-processing.&nbsp; The GPS antennae were Ashtech Duel Frequency Marine Antenna (Ashtech S.A.S., Carquefou, France) that were connected to either Ashtech ProFlex 500 GS or Z-Surveyor receivers and were programmed to record internally at 10 <em>sec</em> intervals.&nbsp; The water salinity was measured near the surface from the dock (Fig. 1) at 4:15 PM on November 3rd, 2014 and 11:35 AM on November 6th, 2014 and was 25.7 and 26.3, respectively.</p>

<p>To convert the absolute pressure to gauge pressure, atmospheric pressure readings from the nearby (~ 13 <em>km</em> away) weather station at Skidaway Institute of Oceanography were employed.&nbsp; Gauge pressure was converted to water depth above the PT by assuming the pressure variation in the vertical direction was solely due to hydrostatic effects.&nbsp; The water density was determined from the PT temperature measurement and the salinity measured at the dock, which was assumed to be equal to the salinity in the vicinity of the PTs.&nbsp; Temperature and salinity were assumed to be vertically homogeneous.&nbsp; To improve the accuracy of the absolute pressure readings (and thus the estimated water surface elevation), the three PTs were calibrated in a 1 deep tank at seven temperatures, ranging from 12 to 26 C.&nbsp; Linear calibration curves were developed to calculate the pressure difference between two of the PTs (stations A and D) and the third reference PT (station F) as a function of temperature.&nbsp; These curves were used during data processing to adjust the pressure data to a common reference pressure.&nbsp; The standard deviations of the mean pressure difference between the PTs at stations A and D and the reference PT at station F were calculated for each calibration temperature.&nbsp; The difference was found to be less than Pa in all cases, which corresponded to less than 1 mm of water surface elevation difference.&nbsp; The water surface elevation was calculated relative to the NAVD88 vertical datum by adding the water depth data to the PT elevation using the dimensions of the stand and the GPS measurement of the antenna position.&nbsp; To arrive at sufficiently accurate water surface elevation measurements, the GPS measurements were post-processed using GrafNet (NovAtel, Calgary, Alberta, Canada), treating the GPS system as a stationary closed loop network.&nbsp; The system included four GPS antenna/receivers (one at each PT and one on the dock) and several Continuously Operating Reference Stations (CORS) operated by the U.S. National Geodetic Survey (NGS).&nbsp; The estimated vertical accuracy from GrafNet was approximately 0.5 <em>cm</em> for all stations.&nbsp; This level of accuracy was obtained using simultaneous GPS measurements.&nbsp; The vertical positions of the PT stands did not vary during the experimental periods.</p>
