Periphyton Nutritonal Data across the freshwater Everglades (FCE): June 2016-Feb 2017

Fatty Acid profiles were obtained for various periphyton sources (food for consumers) accross the freshwater Everglades in June-July 2016, the peak of the wet season, and in January 2017, the peak of the dry season. These data include specific fatty acid markers for each periphyton type (floating mat, benthic mat, epiphyton, and/or filamentous green) collected. Nutritional measurements for various periphyton sources (food for consumers) were also obtained during the same intervals. These measurements include periphyton type (floating mat, benthic mat, epiphyton, and/or filamentous green), periphyton availability (volume, organic content and mineral content), stoichiometric data (TP, C:N, C:P, and N:P), and macronutrient composition (protein, carbohydrate, lipid). These measurements form the basis for the data discussed in the dissertation chapter, "Freshwater herbivores dominate over omnivores in suboptimal habitats because of their ability to exploit low quality resources" by Jessica L Sanchez and Joel C Trexler.2016年6-7月（湿季峰值期）与2017年1月（旱季峰值期），研究团队于淡水大沼泽地（Everglades）全域采集了多种周丛生物（periphyton，消费者的食物来源）的脂肪酸谱数据。本次采集的数据涵盖了各类型周丛生物的特异性脂肪酸标记物，所涉类群包括漂浮垫状周丛生物、底栖垫状周丛生物、附生周丛生物以及丝状绿藻周丛生物。同期还完成了各类周丛生物的营养性状测定，此类周丛生物同样为消费者的食物来源。本次测定的指标包括：周丛生物类型（漂浮垫状、底栖垫状、附生以及丝状绿藻类群）、周丛生物可获取量指标（生物体积、有机组分与矿物组分含量）、化学计量学数据（总磷（TP）、碳氮比（C:N）、碳磷比（C:P）以及氮磷比（N:P）），以及大量营养素组成（蛋白质、碳水化合物与脂质含量）。上述测定数据构成了Jessica L Sanchez与Joel C Trexler所撰写的学位论文章节“淡水草食动物凭借对低质资源的利用能力在亚适宜生境中优于杂食动物”中所讨论的数据集基础。
