1.引进的害虫和病原体是世界各地生态系统受到干扰的一个主要来源。 著名的例子已经产生了宿主丰度的显着减少，包括虚拟灭绝，但大多数引入具有更微妙的影响，难以量化，但由于病原体对宿主繁殖，竞争能力和压力耐受性的影响，可能至少同样重要。一个一般的结果可能是减少主机丰富的竞争对手的丰富度伴随着增加。
1. Introduced pests and pathogens are a major source of disturbance to ecosystems world‐wide. The famous examples have produced dramatic reductions in host abundance, including virtual extirpation, but most introductions have more subtle impacts that are hard to quantify but are potentially at least as important due to the pathogens’ effects on host reproduction, competitive ability and stress tolerance. A general outcome could be reduced host abundance with concomitant increases in the abundance of competitors.
