Data from these experiments were used to estimate predation rates on Tegula that did not display a behavioral fear response. Additionally, we used two predator species of differing attack rates to examine how predator identity might influence the loss of fear in a trophic cascade. The experiment was conducted within laboratory mesocosms at Bodega Marine Lab in 2018.\n\nThis dataset reports the results for experiments with Cancer productus as the predator. See related dataset https://www.bco-dmo.org/node/959441 for results with predator Pisaster ochraceus.\n\ncdm_data_type = Other\nVARIABLES:\nDate_local (unitless)\nDay (days)\nTime_local (unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nTable (unitless)\nSize (millimeters (mm))\nTethered (unitless)\nSex (unitless)\nContainers (unitless)\nAlive (unitless)\nAlive_C (unitless)\nProp (unitless)\n | https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_959435_v1/index.htmlTable | https://osprey.bco-dmo.org/dataset/959435

| log in | [Heat stress experiment data] - Proportions of healthy, pale, bleached, and dead Orbicella faveolata recruits over time during a heat stress laboratory experiment conducted in 2018 and 2019, corresponding to proportions of different symbiont genera hosted (Collaborative Research: Assessing the changing symbiotic milieu on Caribbean coral reefs under climate change: magnitude, tradeoffs, interventions, and implications) | Proportions of healthy, pale, bleached, and dead Orbicella faveolata recruits over time during a heat stress experiment, corresponding to proportions of different symbiont genera hosted.\n\nThese data correspond to research presented in Williamson et al. (2021), published in Coral Reefs and funded in part by the NSF project \"Symbiont Shifts on Reefs\". They were used to test if Orbicella faveolata recruits could establish symbiosis with D. trenchii supplied by nearby “donor” colonies and examined the resulting ecological trade-offs to evaluate early Symbiodiniaceae manipulation as a scalable tool for reef restoration. We exposed aposymbiotic recruits to 29 °C or 31 °C and to fragments of Montastraea cavernosa (containing Cladocopium ITS2 type C3) or Siderastrea siderea (containing D. trenchii). Next, a subset of recruits were exposed to a 60-day heat stress. These data include survivorship and symbiont acquisition rates, symbiont identity and density data (derived using qPCR), polyp area measurements, and scoring of bleaching and survivorship during a heat stress experiment. Overall, proportion of D. trenchii hosted was negatively correlated with polyp size and symbiont density, indicating a trade-off between growth (of both host and symbiont) and heat tolerance. These findings suggest that, while donor colonies may be effective sources for seeding coral recruits with thermotolerant symbionts, practitioners will need to balance the likely benefits and costs of these approaches when designing restoration strategies.\n\ncdm_data_type = Other\nVARIABLES:\nDate (unitless)\nDay (days)\nTemp (unitless)\nTank (unitless)\nAdult (unitless)\nAlive (per recruit)\nSymb (per recruit)\nPale (per recruit)\nBleached (per recruit)\nSurv (unitless)\n...
