• Premise of the study: Slow‐growing understory cycads invest heavily in defenses to protect
the few leaves they produce annually. The Neotropical cycad Zamia stevensonii has …

Five new congeners of elaiomycin featuring the rare azoxy function were isolated from
Streptomyces sp. strain HKI0708. Individual elaiomycins exhibit specific antimycobacterial …

Brood‐site pollination mutualisms represent extreme levels of reciprocal specialization
between plants and insects. Several studies have revealed intimate associations between …

Aggregations of conspecifics are ubiquitous in the biological world. In arthropods, such

population characterized by low seedling and high adult tree density, in order to improve …

Cycads are a group of slow-growing, perennial, dioecious plants which in geological times
thrived during the Mesozoic era. The present worldwide complement of around 300 species …
