查询词典 accompanying species

Firstly, an invasive species must be invasive enough in itself or has some biological distinction, such as quantitative and qualitative differences in the genome, or patterns of recombination. Secondly, to invade successfully, a new environment for an invasive species must be invasible, and this we may call the ecological basis of invasion. An invasive species may need to establish new interactions with other species, especially those mutualistic relations such as animal related pollination, seed dispersal by animals, mycorrhizal fungi, and symbioses between plants and nitrogen fixing bacteria.

首先从其自身来说，需要有足够的入侵性，这可以认为是入侵种的生物学基础，可能表现为具有多倍性、一定的遗传变异、杂合性或表型可塑性，以及不同的交配系统等；其次一个物种的入侵成功还取决于入侵生境的可入侵性，这可以认为是入侵种的生态学基础，而新的种间关系的形成，尤其是入侵种与其他种类的互惠共生关系的建成是关键。
