Meanwhile, we highlight several research corners for future further study, the trade-offs on resource allocation within perennial plant had not been proved, the relationship of neighbor effects and reproductive allocation was still not so clear for individual plant, there was no definite conclusion on perennial plant reproductive strategy under different neighbor effects and different habitats. The relationship between reproductive allocation and sexual allocation , the cause of resource distribution in anthotaxy structure, the similarities and differences of reproductive allocation and the maintain mechanism within all kinds of reproductivest rategy need a further investigation. In addition, a molecular study is required for explaining the variation mechanism and the biological meanings on seed size research.
指出生活史研究仍存在不足首先是研究内容上,资源分配在多年生植物中的权衡仍未被有力证明,邻体效应与繁殖分配的关系在个体水平上仍不明了,多年生植物在不同邻体效应和生境下将采取何种繁殖对策目前尚无明确的结论;繁殖分配与性分配之间的关系,引起花序结构上资源分配差异的原因,各种繁殖对策中繁殖分配异同与维持机制等问题仍有待于进一步的研究;种子大小的变异机制以及生物学意义仍未得到令人满意的答复,更需分子水平上的研究来解释其机理。

The main fi ndings were i copper was strongly bound to organic layer and seemed to be the main pollutant in the ecosystem while zinc was the most mobile element and did not accumulate to any specifi c part of the ecosystem, ii the forest mosses and epiphytic lichens were the most sensitive plant species and the seedlings of the vascular plants that had survived near the smelter were absent, iii there was a highly resistant soil decomposer community near the smelter although the activity of the soil animals and microbiota was low and their community structure altered, iv many insect species also suffered from pollution although the adverse effects caused by forest pests increased with pollutant load, v the low survival rate and breeding success of hole-nesting passerines near the smelter was caused by habitat changes and the quality of food, vi the adverse effects seem to be to some extent reversible after decreased pollutant load or remediation actions.

Large supply of non-hybrid seeds for vegetables, grains and herbs; make sure they are of the non-GMO, non-hybrid, propagating variety; also be sure to have instructions on how to harvest seeds including information on "moldering" techniques to properly collect seeds from certain plants such as tomatoes; note lastly that due to damp low-sunlight conditions many crops will not grow without growing lights and protection from rain; special research is therefore required on which crops will grow best (for instance, patty rice should grow better than wheat under damp conditions); also be sure to take into account the climactic change which results from the change in latitude due to the pole shift as a location which does not change greatly in latitude will fare better than one which falls in the vicinity of the new poles for instance; the pole shift theory presented on Zeta Talk states that the terrestrial North Pole will move to the middle of the Atlantic off the bulge of Brazil and ultimately one will need to observe the climate and the position of the sun to figure out the new latitude, and either adapt or re-locate as needed
要有许多蔬菜,谷物和草药的的非杂交种子;确信它们是非转基因,非杂交的,是用于繁殖的品种。也得确信具有怎样收获种子的指导书说明,包括&制造&技术方面的信息,以便恰当地收集某些植物的种子,例如西红柿。最后得注意,由于幽暗的低阳光环境,在没有阳光,以及没有其进行雨水防护的情况下庄稼将不会下生长。因而需要进行特别的研究,看看哪种庄稼在这种条件下生长得最好(例如,在昏暗的状况下,水稻应该比小麦生长的更好)。也要确信考虑了极移造成纬度改变,因而导致气候变化。例如,与那些位于新极点附近的地方相比,纬度变化不特别大的地方情况要好得多。齐塔人之声讲述的极移理论表明了地球北极会移动到大西洋中部的巴西隆起处。最后需要观察气候状况以及太阳的位置,以弄清楚新的纬度,根据需要,即可适应当地的条件,又可再次搬迁。
