Response consistency of six PFTs which are good (specific) indicators for grazing pressure at least in one biome.

aPFTs with a sensitive response to grazing had a significant contribution of the grazing-related PC to their final linear models, but other predictor variables had larger effect sizes. PFTs with a specific response to grazing also had a sensitive response, but responded stronger to grazing than to other predictor variables (largest effect size for the grazing-related PC). Insensitive PFTs had a non-significant contribution of grazing-related PC to their final linear models. Arrows indicate the direction of response (↑ positive response to increased grazing pressure, ↓negative response). For details of final linear models refer to Tables S2 and S3.对放牧具有敏感响应的植物功能型（Plant Functional Types, PFTs），其最终线性模型中与放牧相关的主成分（Principal Component, PC）贡献显著，但其余预测变量的效应量更大。对放牧具有特定响应的植物功能型，同样表现出敏感响应，但其对放牧的响应强度高于对其他预测变量的响应（与放牧相关的主成分效应量最大）。不敏感的植物功能型，其最终线性模型中与放牧相关的主成分贡献不显著。箭头指示响应方向：↑代表对放牧压力增加呈正响应，↓代表负响应。有关最终线性模型的详细信息，请参见附表S2与S3。
