LTR - Pomacentrids

<p>Pomancentrids identity, size and abundance were enumerated around 192 patch reefs. Data were collected in 2003-2006, 2009, 2012, and 2014 at 192 reefs. Beginning in 2012, reefs 129-144 and added reefs 193-198 were manipulated for a project studying the effects of vermetid removals; information pertaining to this manipulation can be found in the project “Spatial patterns of coral-vermetid interactions: short-term effects and long-term consequences”. All data collected on reefs 129-144 and 193-198 beginning in 2012 can also be found under that project. In 2012, additional data were collected – the number of vermetids on each patch reef at the time of this survey. Common Pomancetrids were recognized and size class determined. These data are part of the larger data set describing the biological and physical conditions of the 192 reefs. Together all of these data provide information about the factors that may influence (or be influenced by) <em>Thalassoma</em> and Vermetid.</p>

研究人员对192块斑礁周边的雀鲷科类群（Pomancentrids）的种类组成、个体体型及种群丰度开展了系统性计数统计。相关调查数据于2003至2006年、2009年、2012年及2014年在上述192块斑礁上采集完成。自2012年起，研究人员对编号129至144的斑礁以及新增的193至198号斑礁实施了人为操控实验，以探究移除蛇螺（Vermetids）的生态效应；该实验操控的相关细节可查阅项目《珊瑚-蛇螺相互作用的空间格局：短期效应与长期后果》。2012年起在129至144号及193至198号斑礁上采集的全部数据，同样可在该项目数据库中获取。2012年还额外采集了补充数据：即本次调查时每块斑礁上的蛇螺个体数量。研究人员对常见雀鲷科类群进行了物种鉴定，并划分了其体型等级。本数据集隶属于描述192块斑礁生物与物理环境特征的大型综合数据集。上述全部数据集可用于解析可能影响锦鱼属（Thalassoma）与蛇螺，或受二者影响的各类生态因子。
