Main point: introduce a series of experiments (mainly of BG and GS) to understand mechanism of plant competition
Part I: para 1-3: introduce plant competition (common and well documented: e.g. through competing resources) but botanists don't understand the mechanism that controls plant competitive ability
Part II: para 4-10: introduce a series of experiments conducted on BG and GS to test hypotheses to understand the mechanisms
-> key method: comparative
-> key conclusion: spatial patterns influence growth, not caused by neighborhood competition but likely caused by gap colonization (competition between different generations)
-> conclusion details: BG's blade litter structurally blocked GS's seedling
Part III: para 11: conclude that spatial pattern influences plant competition and mechanism involved in example experiments is gap colonization, with further implication of succession and time lag. |
