Gobiomorus dormitor divergence between prey regimes

Data associated with Gobiomorus dormitor populations inhabiting blue holes in the presence and absence of fish prey. Demographic and habitat data was collected using underwater survey techniques. Diet data was collected using gastric lavage and stomach dissections. Morphology data was taken from standardized photographs of live individuals and feeding/kinematics and performance data was calculated from video-taped lab trials. See “Predicting ecological and phenotypic differentiation in the wild: a case of piscivorous fish in a fishless environment, Martin, Ryan, McGee, Matthew, Langerhans, Brian” for a detailed description of the methods.本数据集涵盖栖息于存在与缺失鱼类猎物的蓝洞（blue holes）生境中的溪鳢（Gobiomorus dormitor）种群相关数据。其中，种群统计与栖息地数据通过水下调查技术采集；摄食数据采用胃灌洗法与胃部解剖法获取；形态学数据取自活体个体的标准化摄影影像；摄食运动学与运动性能数据则由实验室录制的视频试验计算得出。有关本研究方法的详细说明，请参阅论文"Predicting ecological and phenotypic differentiation in the wild: a case of piscivorous fish in a fishless environment"，作者为Martin, Ryan、McGee, Matthew与Langerhans, Brian。
