Numerous studies have evaluated the qualitative and quantitative effectiveness of several animal species in each phase of the endozoochory. For the “seed germination and growth” phase, the ideal method of evaluation is to track the germination and seedling growth of seeds where they were dispersed by animals, but few studies have done so. Furthermore, because these studies were limited to measurements such as the seedling density and seedling growth over time or comparison with surrounding areas, survival rates, and factors specific to seedling mortality are unclear. This study aimed to qualitatively evaluate the effectiveness of one of the main seed dispersers in temperate forest ecosystems in Asia, raccoon dogs (Nyctereutes procyonoides), in the seed germination and growth phase. Seedlings of four tree species germinated in their latrines: Ginkgo biloba, Diospyros kaki, Aphananthe aspera, and Celtis sinensis. It was previously thought that most seeds in latrines germinated but died off quickly through competition within seedlings. However, this study has verified that in specific environmental conditions, seedlings of these four species live for at least one year after germination. In particular, G. biloba has a large seed size, and its survival rate of 85% could indicate that the raccoon dog latrines are suitable for its dispersal. These results demonstrate the effectiveness of seed dispersal raccoon dogs in the seed germination and growth phase.

大量研究已经评估了几种动物在定殖内吞阶段的定性和定量有效性。对于“种子发芽和生长”阶段，理想的评估方法是跟踪种子被动物分散的种子的发芽和幼苗生长，但很少有研究这样做。此外，由于这些研究仅限于诸如幼苗密度和幼苗随时间的生长或与周围区域的比较之类的测量，因此尚不清楚存活率和特定于幼苗死亡率的因素。这项研究旨在定性评估亚洲温带森林生态系统中主要的种子分散剂之一-子（Nyctereutes procyonoides）），处于种子发芽和生长阶段。四种树种的幼苗在它们的厕所中发芽：银杏，柿，柿，阿斯潘纳斯和西提斯。以前认为，厕所中的大多数种子发芽但由于幼苗内部的竞争而很快死亡。但是，这项研究已经证实，在特定的环境条件下，这四种物种的幼苗在发芽后至少可以生存一年。特别是银杏它的种子大小很大，其成活率达85％可能表明the狗厕所更适合其散布。这些结果证明了种子传播浣熊狗在种子萌发和生长阶段的有效性。
