Pathogens are powerful evolutionary forces shaping the structure and dynamics of both individual species and of the communities of which they are part, at a broad range of genetic, ecological, spatial, and temporal scales. At all these levels their impact varies from the subtle and little recognized through to the most obvious destruction. Today the direct role of pathogens in natural plant communities is better recognized than at previous times, although the nuances of their interactions and the cascade of ramifications that can flow through changing biotic and abiotic effects are only now gaining recognition. However, as human influence on pathogens increases--either directly through enhanced if accidental dispersal, or through anthropogenic impacts on climate--we may expect to see increasing evidence of pathogens affecting plant species, community structure, and ecosystem function.

植物群落中疾病的当前和未来动态。

病原体是强大的进化力，可在广泛的遗传，生态，空间和时间尺度上塑造单个物种及其所属社区的结构和动力学。在所有这些级别上，它们的影响范围从微妙的，鲜为人知的破坏到最明显的破坏。如今，病原体在天然植物群落中的直接作用比以前得到了更好的认识，尽管它们之间的细微差别以及可以通过不断变化的生物和非生物作用流过的一系列后果现在才获得认可。但是，随着人类对病原体的影响不断增加（无论是通过意外扩散直接增强效果，还是通过对气候的人为影响），我们都有望看到越来越多的病原体影响植物物种的证据，
