Synergistic Impacts of Novel Antifouling Paints and Heat Stress on Pacific Oysters

These raw data examine the synergistic effects of the sustainable, rapidly degraded antifouling biocide tralopyril combined with climate change stressors on Pacific oyster (Crassostrea gigas) mortality. Oysters were exposed to tralopyril under ambient temperature and a heatwave, then to a simulated tidal air exposure in a controlled laboratory setting to investigate how mortality changed with heat and toxin. This dataset includes all combinations of a fully factorial combination of heat and two toxin doses, recording the mortality of individuals in each of four replicates per treatment combination (n=4) at five different timesteps. Mortality was recorded before any treatment (T0), after toxin-only exposure (T1), after concurrent toxin-heat exposure (T2), after a tidal desiccation event (T3), and after a rest period (T4). Experimental oysters were collected from both a pristine habitat and a chronically polluted habitat to test population effects related to contaminant exposure history.本原始数据集探究了兼具可持续性与快速降解特性的防污生物杀灭剂三氯吡咯（tralopyril）与气候变化胁迫因子联合作用对太平洋牡蛎（Crassostrea gigas）死亡率的协同效应。实验将太平洋牡蛎分别置于常温环境与热浪胁迫下暴露于三氯吡咯，随后在可控实验室环境中开展模拟潮汐露空暴露实验，以解析温度与毒素共同作用下牡蛎死亡率的变化规律。本数据集涵盖温度与两种毒素剂量的全因子实验所有组合，记录了各处理组合下4个生物学重复（n=4）的个体死亡率，共设置5个不同时间节点。死亡率的记录节点依次为：所有处理实施前（T0）、仅毒素暴露结束后（T1）、毒素与热胁迫联合暴露结束后（T2）、潮汐干燥处理结束后（T3），以及恢复期结束后（T4）。实验所用牡蛎分别采集自原生未受污染栖息地与长期受污染栖息地，以检验污染物暴露历史对种群效应的影响。
