Pathogens and insect herbivores drive rainforest plant diversity and composition

Pathogens and insect herbivores drive rainforest plant diversity and composition

In an article titled, “Pathogens and insect herbivores drive rainforest plant diversity and composition,” published inNature  (506: 8-55) on its online edition of 22nd January, ’14 the lead author Robert Bagchi and his seven associates affiliated with well-known European and UK laboratories reported that the processes that maintain the diversity of Flora can be explained by the Janzen–Connell hypothesis which suggests that specialized natural enemies such as insect herbivores and fungal pathogens maintain high diversity by elevating mortality when plant species occur at high density (negative density dependence; NDD). The authors demonstrated experimentally that changes in plant diversity and species composition are caused by fungal pathogens and insect herbivores. They have further shown that treating seeds and young seedlings with fungicides significantly reduced the diversity
