种间关系 Janzen-Connell假说认为,某些植物母株周围 累对自身有害的病原菌、昆虫等,从而抑制母株附近自身种子 的萌发和幼苗的生长,故亚热带常绿阔叶林中楠木幼苗距离母 株越远,其密度越大,能用该假说合理解释,A不符合题意;若 符合该假说,鸟巢兰种子远离母株萌发,有利于幼苗生长,但此 时缺少土壤共生菌,幼苗死亡,...
该研究以吉林蛟河针阔混交林中4个常见树种为研究对象, 利用杀菌剂处理及不同树种幼苗的栽种控制实验来检验Janzen-Connell假说, 计算生物反馈及特异性反馈, 并依据高通量测序方法测定土壤真菌多样性, 检验不同处理组间差异性。利用方差分解分...
Testing Janzen-Connell hypothesis based on plant-soil feedbacks in a temperate coniferous and broadleaved mixed forest 作为植物与土壤交互作用的重要媒介在森林生态系统研究中越来越受到重视(Packer &Clay,

comparison with seed dispersed at shorter distances. This indicates that the probability of surviving and establishing in the population is a function of distance to their parental trees (both male and female) congruent with the Janzen-Connell (J-C) hypothesis13,14. According to J-C, recruitment...
为探究生境面积大小对Janzen-Connell (JC)效应中密度和距离制约的影响以及驱动机制,为生境破碎化背景下植物多样性的维持机制提供科学依据,本研究在Web of Science数据库中收集并筛选出1970-2019年全球50个森林地点作为数据基础,采用荟萃分析法分析密度和距离制约实验中不同类型驱动者的效应值大小,并采用分段回归和非分段...

The deleterious effects of natural enemies on seedling recruitment and survival, assessed at the community scale, increase with the local density of conspecific adults. While this pattern is consistent with the Janzen-Connell hypothesis, the relationship between adult density and seedling survival is wea...
Janzen-Connell假说植物-土壤反馈距离制约针阔混交林幼苗土壤真菌目前对森林生物多样性维持机制的研究主要集中在检验地上生物的多度丰富度等内容,物种之间的交互作用及地下真菌是否影响生物多样性的维持在很大程度上还是未知的.探讨土壤真菌的作用及植物-土壤反馈在植物生长过程中的作用有重要意义.该研究以吉林蛟河针阔混交...
