Scatter-hoarding rodent foraging preference on nutrient content is mediated by seed size

摘要

This study was supported by the National Natural Science Foundation of China (31770570, 31971444, 31470494) and the CAS “Light of West China” Program. Authors’ Contributions B.W. conceived the ideas and designed methodology, B.W. and X.Y. collected the data, B.W. analyzed the data and led the writing of the manuscript. Both authors read and approved the final manuscript. Supplementary Material can be found at . Acknowledgments We thank Shangri-La Alpine Botanical Garden for logistical support for fieldwork.
