摘要
为了解东北地区寒温带森林啮齿动物对不同种子特征的选择规律,2018年和2019年夏季,在张广才岭地区采用标签标记法追踪调查释放的红松(Pinuskoraiensis)、毛榛(Corylus mandshurica)、蒙古栎(Quercus mongolica)3种林木种子,测定啮齿动物取食或扩散后的种子特征.调查结果表明:红松、毛榛、蒙古栎三种林木种子形态学特征和营养成分具有明显的差异,这些种子特征的差异可能会影响取食者的偏好和决策.种子大小、种子质量、种仁质量及比值、种皮厚度与硬度、种子的营养物质与其他成分等影响啮齿动物取食或者储食的重要因素,啮齿动物对种子做出的行为,是基于种子特征而做出的综合评估的结果 .
Tounderstand the selection pattern of rodents on different seed In order to understand the selection of different seed characteristics by rodents in cold temperate forests in Northeast China,in the summers of 2018 and 2019,three forest seeds of Pinus koraiensis,Corylus mandshurica,and Quercus mongolica were tracked and investigated by label tagging in Zhang Guangcai mountains and the seed characteristics of rodents after feeding or spreading were determined.The results showed that there were obvious differences in seed morphological characteristics and nutrient composition of red pine,woolly hazel and Mongolian oak seeds,which will have an impact on the decisions of the predators.Ro-dent's selection of seeds is based on a comprehensive evaluation of various seeds'proper-ties including size,kernel quality,and the specific value between seed and kernel quality,and thickness,hardness,nutrients.
