See the \"Related Datasets\" section for more datasets from this study.\n\nStudy description:\n\nClimate change is quickly altering marine environments by increasing sea surface temperatures and decreasing dissolved oxygen (DO) levels. Although these effects have been well-studied on the declining corals, the impact of temperature and dissolved oxygen extremes on the functional roles of sponges remains primarily unexamined. This study, conducted in the Lower Florida Keys, FL (USA) had two objectives: (1) compare sponge abundance and size distributions on hardbottom before and after the summer 2023 heatwave, and (2) investigate the filtration capacity of eight common sponge species from the Florida Keys with different morphologies (tubular vs. spherical) and microbial associations (HMA vs LMA) in mesocosms that simulated elevated temperature and hypoxic conditions for ~45 minutes. Field surveys by divers at the same 24 sites in May 2023 and June 2024 revealed that the abundance and size of spheroid sponges (e.g., Speciospongia vesparium, Hippospongia lachne) declined after the heatwave, but no noticeable effects were detected among the other species surveyed. The mesocosm experiments revealed tubular and LMA sponges consistently exhibited higher filtration efficiency of high nucleic acid (HNA) bacteria than spherical and HMA sponges under most treatment conditions. Elevated temperatures (2.5 to 5°C above ambient) significantly reduced HNA bacteria filtration capacity in spherical and HMA sponges (-43.6% ± 5.1 to -21.5% ± 4.4), whereas LMA tubular sponges were unfazed (-52.3% ± 11.6% to -62.6% ± 8.8%). The findings imply that future reef communities may shift toward more sponge dominance, particularly by heat and hypoxia-resistant, fast-growing LMA species, potentially altering ecosystem functions like water quality regulation, nutrient cycling, and habitat structure.\n\ncdm_data_type = Other\nVARIABLES:\nDate (unitless)\nDay (days)\nTable (unitless)\nTank (unitless)\n...
