| 本文在分析鹤科（Gruidae）鸟类的鸣声特征的基础上，结合其分子系统树，重建了鸣声特征的演化，并检验了体重与鸣声特征、及鸣声特征之间在演化上的相关性。同时比较了体重与鸣声特征在物种间的关系。演化支上各物种体重的变化与鸣声时长特征的变化存在显著的关联（对数线性模型，似然比 = 9.69，P = 0.002；Cohen’s d = 1.48）：体重的增加伴随着鸣声时长的增加。鸣声特征之间在演化上没有显著的关联（对数线性模型，似然比 ≤ 0.15，P ≥ 0.701；Cohen’s d ≤ 0.17）。在物种间鸣声时长与体重存在显著的正相关（Pearson相关分析，r = -0.54，P = 0.048；Cohen’s d = 1.27）；鸣声的主频特征与体重存在显著的负相关（Pearson相关分析，r = -0.56，P = 0.036；Cohen’s d = 1.37）。本文以鹤科鸟类鸣声为例，分析了非鸣禽鸟类鸣声特征的演化，及影响鸣声特征的因素。 |

| Cranes (Gruidae) have elaborate vocal displays in communication. We measured sound characteristic from total 15 species within Gruidae. Six variables were measured: duration of note, number of elements within note, minimum frequency of fundamental, maximum frequency of fundamental, minimum frequency of peak, maximum frequency of peak (Table 2). We used a princial component analysis to compress the original six sound variables into three comprehensive sound characteristic: fundamental frequency characteristic, peak frequency characteristic, temporal characteristic (Table 1). We estimated the ancestral sound characteristic by using phylogeny (Fig.3), and found positive relationship between temporal characteristic"s and body weight"s evolutionary changes (Loglinear model, Likelihood ratio = 9.69, P = 0.002; Cohen’s d = 1.48) (Fig.4). We didn"t find any relationship within evolutionary changes in sound characteristic (Loglinear model, Likelihood ratio ≤ 0.15, P ≥ 0.701; Cohen’s d ≤ 0.17) (Fig.5). Independent contrasts show positive relationship between temporal characteristic and body weight (Pearson correlation, r = -0.54, P = 0.048; Cohen’s d = 1.27), and negative relationship between peak frequency characteristic and body weight (Pearson correlation, r = -0.56, P = 0.036; Cohen’s d = 1.37)(Fig.6). Our results provide insight into how evolutionary changes in sound characteristic in a group of non-oscine bird (Gruidae). |
