Tropical Forest Mycology

Research Issue

[photo:] Amatina jacksonianaThe Center for Forest Mycology Research (CFMR, part of the Northern Research Station of the US Forest Service) leads critical research on the biology of tropical fungi native to Hawaii, US territories in the Caribbean (Puerto Rico and the US Virgin Islands) and to other countries in the Caribbean Basin. The primary goals of this research are to: (1) recognize emerging tropical forest diseases, especially those with the potential to spread to the continental US and (2) identify the effects of environmental change on the distributions of beneficial and harmful forest fungi.

Effective prevention requires the identification and classification of tropical fungi that cause disease, many of which have not yet been scientifically described. The subtropical mainland US would likely provide an acceptable habitat for many fungi from the Caribbean Basin. Conversely, tropical islands including those in US territories and Hawaii have a long history of damage from introduced species, such as the Guava Rust fungus. Other emerging diseases introduced to the eastern US, such as the newly described fungal pathogen that causes Laurel Wilt, pose a significant threat to native forests and to the avocado industry throughout the Caribbean Basin. The USDA inspection and quarantine programs rely on research in the Caribbean Basin and other tropical areas to detect potential threats to forest health. Inspectors also depend on new biosystematics research that provides tools developed by CFMR and partners to distinguish foreign pathogenic fungi from the many native and beneficial species.

Our Research

The great biodiversity of tropical forest fungi presents a potential wealth of undescribed biochemicals. Cultures of tropical fungi developed and maintained in the CFMR culture collection are frequently screened by manufacturing industries for useful enzymes and by pharmaceutical companies seeking new bioactive compounds to develop for new medical treatments. The availability of fungal cultures from tropical countries is often limited by national patrimony laws, but CFMR cultures derived from Hawaii and US territories are available for industrial screening without complex restrictions or agreements.
