Measures of evolutionary signal for freshwater algal ecological and physiological traits.

K = Blomberg's K (p-value based on randomization), Pagel's λ (p-value based on log-likelihood ratio test with λ set to zero), Moran's I (p-value based on randomization and one-way hypothesis test). Biovolume and long axis length are measures of algal size and morphology respectively; α light, α nitrate and α phosphate are the initial rates of response of species' growth rates to increases in resource availability; μmax light, μmax nitrate and μmax phosphate are the maximum per capita population growth rates of each species when that particular resource is unlimited; I*, N* and P* indicate concentrations of the resource (molar for N and P, μEinstein for I) at which the population growth rate equals zero; %C, %N, % P indicate the mass percent of carbon, nitrogen and phosphorus; C:N, C:P and N:P indicate the molar ratios of carbon (C), nitrogen (N) and phosphorus (P) of each species. N is the number of species.本次数据集涵盖的统计量指标K包含以下三项：布卢姆伯格K值（Blomberg's K，基于随机化检验的p值）、佩格尔λ值（Pagel's λ，基于以λ=0为原假设的对数似然比检验得到的p值）以及莫兰I值（Moran's I，基于随机化检验与单向假设检验得到的p值）。生物体积（Biovolume）与长轴长度分别为藻类大小与形态的度量指标；α_light、α_nitrate与α_phosphate分别代表各物种生长速率随资源可获得性提升的初始响应速率；μmax_light、μmax_nitrate与μmax_phosphate分别指代当对应资源不受限制时，各物种的最大个体种群增长率；I*、N*与P*分别表示种群增长率为零时的资源浓度（氮、磷以摩尔为单位，光照I以微爱因斯坦为单位）；%C、%N与%P分别代表碳、氮、磷的质量百分比；C:N、C:P与N:P分别表示各物种碳（C）、氮（N）、磷（P）的摩尔比；N为物种总数。
