Dominant microbe taxa from Florida Keys National Marine Sanctuary, 2009-2012 (HERBVRE project)

<p>This dataset contains microbial orders that rose to dominate at least one sample.&nbsp;Values quantify the number of samples in which each order was the most abundant, as well as average metadata values for the samples in which that order became most abundant. Metadata values calculated are temperature, overall community evenness, the cover of all upright algae, tall turf algae, or cyanobacteria, and the average abundance of the dominant taxon.</p>

<p><u>Natural history of the study site:&nbsp;</u><br />
This experiment was conducted in the area of Pickles Reef (24.99430, -80.40650), located east of Key Largo, Florida in the United States. The Florida Keys reef tract consists of a large bank reef system located approximately 8 km offshore of the Florida Keys, USA, and paralleling the island chain. Our study reef is a 5-6 m deep spur and groove reef system within this reef tract. The reefs of the Florida Keys have robust herbivorous fish populations and are relatively oligotrophic. Coral cover on most reefs in the Florida Keys, including our site, is 5-10%, while macroalgal cover averages ~15%, but ranges from 0-70% depending on location and season. Parrotfishes (<em>Scaridae</em>) and surgeonfishes (<em>Acanthuridae</em>) are the dominant herbivores on these reefs as fishing for them was banned in 1981. The other important herbivore on Caribbean reefs, the urchin <em>Diadema antillarum</em>, remains at low densities across the Florida Keys following the mass mortality event in 1982-3.</p>

本数据集收录了至少在一个样本中成为优势类群的微生物目（microbial orders）。各数值分别量化了对应微生物目成为丰度最高类群的样本数量，以及该类群成为优势类群的样本的平均元数据（metadata）值。本次计算的元数据指标包括温度、群落整体均匀度、所有直立藻类盖度、高 turf藻类（turf algae）盖度、蓝细菌（cyanobacteria）盖度，以及优势类群的平均丰度。

<u>研究区域自然概况：</u><br />
本实验在美国佛罗里达州基拉戈岛东侧的皮克尔斯礁（Pickles Reef，坐标：24.99430, -80.40650）海域开展。佛罗里达礁岛群礁滩由一处离岸约8公里、平行于岛链的大型岸礁系统构成。本研究的礁体属于该礁滩内的5-6米水深槽脊礁系统（spur and groove reef system）。佛罗里达礁岛群的礁体拥有丰富的植食性鱼类种群，且整体处于相对贫营养状态。包括本研究站点在内的多数佛罗里达礁岛群礁体的珊瑚盖度为5%-10%，大型藻类盖度平均约15%，但因区域和季节不同，盖度范围可从0至70%。由于1981年起禁止捕捞鹦嘴鱼科（Scaridae）和刺尾鱼科（Acanthuridae）鱼类，这两类群成为该礁域的优势植食动物。加勒比海礁域另一类重要植食动物——长刺海胆（Diadema antillarum），在1982-1983年大规模死亡事件后，其种群密度在佛罗里达礁岛群海域始终处于较低水平。
