The goal of this analysis was to test whether temperature had an effect on competition above and beyond the observed, regional differences in competition. Specifically, we tested for associations between average water temperature and estimates of the strength of competition. Competition was measured at the scale of the survey site, and given the structure of the data (time-series observations of densities at many locations), we have spatially-replicated estimates the strength of competition. Temperature data were not available for the exact survey locations, but we were able to obtain records of sea surface temperature from nearby weather buoys during the survey period. Data from the survey period (2006-2016) were accessed from the Coastal Data Information Program at Scripps Institution of Oceanography (http://cdip.ucsd.edu). Temperature data are available from 25 stations located throughout California. For sites located between two buoys, we used the average temperature weighted by the distance to each buoy. Although distances from the temperature stations to the sites were on the order of 10’s of kilometers, the survey sites covered over 1000km of coastline, and we believe this analysis captured most of the spatial variation in water temperatures.

两种温带礁鱼竞争的大规模研究：温度、功能多样性和动态区域差异

该分析的目的是测试温度是否对竞争产生超出观察到的区域竞争差异的影响。具体来说，我们测试了平均水温与竞争强度估计之间的关联。竞争是在调查地点的规模上衡量的，并且考虑到数据的结构（许多地点密度的时间序列观察），我们对竞争强度进行了空间复制估计。无法获得确切调查地点的温度数据，但我们能够在调查期间从附近的气象浮标获得海面温度记录。调查期间（2006-2016 年）的数据来自斯克里普斯海洋研究所的海岸数据信息计划 (http://cdip.ucsd.edu)。温度数据可从遍布加利福尼亚的 25 个站点获得。对于位于两个浮标之间的站点，我们使用由到每个浮标的距离加权的平均温度。尽管从温度站到站点的距离大约为 10 公里，但调查站点覆盖了 1000 多公里的海岸线，我们相信该分析捕获了水温的大部分空间变化。
