Seven new polyketides including three chromone derivatives (1‐3) and four linear ones incorporating a tetrahydrofuran ring (4‐7), along with three known compounds (8‐10), were obtained from the fermentation of an endophytic fungus (Chaetomium sp. UJN‐EF006) isolated from the leaves of Vaccinium bracteatum. The structures of these fungal metabolites have been elucidated by spectroscopic means including...

While the effects of living lianas on species diversity, ecosystem carbon, and nutrient dynamics are receiving increasing attention, the role of dead lianas in forest ecosystems has been little studied and is poorly understood. Trees and lianas coexist as the major...
