Abstract:

These data were recorded during surveys of a tethering experiment conducted on June 7, 2018, during which 180 tethered prey were deployed in two habitat types (seagrass and mudflat) in the Upper Laguna Madre, Texas, USA (27.544006, -97.285912). In each habitat, the following prey types were deployed: squidpops (1 cm2 discs of dried squid (Duffy et al. 2015) attached to 5 cm tethers, n=50), live (n=20) and dead (n=20) pinfish (Lagodon rhomboides, 4 cm fork length, attached to 20 cm tethers) at midday in each habitat. The presence/absence of tethered prey on each stake was observed and recorded after 1 hour and 24 hours. The rate of decay (i.e., disappearance or consumption rate of tethered prey over time) was calculated as the slope of an exponential model fit to discrete observations of the presence/absence of tethered prey over time. Additional environmental variables (temperature, salinity) were also recorded at the site.

Description:

Tethering Case Study

Methods: On June 7, 2018, we deployed 180 tethered prey in two habitat types in the Upper Laguna Madre, Texas, USA (27.544006, -97.285912). We used monofilament line to tether prey, and attached the line to garden stakes using electrical tape at a height of 30 cm above the substrate. We spaced staked tethers at least 1 m apart and in water 60 cm deep. In each habitat (n=2) we deployed squidpops (1 cm2 discs of dried squid (Duffy et al. 2015) attached to 5 cm tethers, n=50), live (n=20) and dead (n=20) pinfish (Lagodon rhomboides, 4 cm fork length, attached to 20 cm tethers) at midday in each habitat, and recorded the presence/absence of tethered prey on each stake after 1 hour and 24 hours.

Manipulated factors: We varied prey type (squid bait versus pinfish) and vital status (live versus dead pinfish). We spatially varied tethers by deploying them across two habitats spaced 200 m apart: continuous seagrass bed (dominated by Halodule wrightii) and mudflat.

Additional data collection: On the same day as the tethering deployments, we sampled the macrofaunal community in each habitat using throw traps (1 m2, n=3 per habitat) and seines (60 m2 area, n=1 per habitat). We collected, sorted, and identified all animals >5 mm to the lowest possible taxonomic resolution. On June 3, 2019, we deployed 60 live brown shrimp in the same location and midday time frame as above, with 30 shrimp deployed over bare sediment and 30 shrimp deployed over seagrass. Tethered animals were placed a minimum of 5 m apart and were checked after 15 minutes, 1 hour, and 4 hours. We set up GoPro cameras to record a subset of these tethers (3 over mudflat and 5 over seagrass) and then repeated the video recording assay a second time that night for a total of 16 recordings. Nighttime deployments were set up with local red lights to allow for recording the predation events.

Abstract:

Predation is a key process that influences the structure and functioning of ecosystems. Tethering experiments, which involve restraining prey or prey analogs in field settings, are used to evaluate predation with minimal manipulation of predators and the environment. However, tethering experiments alter the behavior of mobile prey, an issue that increases in severity with prey mobility and reliance on that mobility to evade predators, resulting in artifacts that complicate the interpretation of experimental findings. Given their widespread and rapidly evolving use, we review and reconsider the applications of tethering experiments in marine ecosystems, their utility in measuring predation, associated artifacts, theoretical, methodological, and statistical considerations and challenges, and how to overcome these. Breaking down the predation process into its successive stages (encounter, attack, capture, and consumption), we consider that tethering experiments effectively measure two major aspects of predation: (1) relative predation rates (requiring all four stages, and resulting in successful predation) and (2) predation risk (requiring only encounter and attack). We suggest that tethering experiments be designed to test hypotheses that target particular stages or all stages of the predation process and its drivers, through manipulating tethering experimental designs, conducting direct observations of tethering experiments, collecting additional community or environmental data, combining tethering with other experimental approaches, and through statistical analyses. This general approach facilitates both our understanding of the limitations and utility of tethering experiments to compare patterns and identify drivers of predation rates and risk in the field, topics of study that remain underrepresented in the literature.
