Effects of daily temperature fluctuations that mimic on-site environmental conditions were tested on seed germination and development in Dracula felix, a native epiphytic orchid from the neotropics. Mature seeds collected population lost their viability 60% to 37.78% 0% after 8 16 weeks., respectively, under 22 ± 2 °C. Seed was completely when maintained at −10 °C dark. Less than 50% observed D...

Several key characteristics of the species-rich orchid family are due to its symbiotic relationships with pollinators and mycorrhizal fungi. The majority of species are insect pollinated and show strong adaptations for outcrossing, such as pollination by food- and sexual-deception, and all orchids are reliant on mycorrhizal fungi for successful seedling establishment. Recent studies of orchid p...

Beginning with the report by Stierle and Strobel in 1993 on taxol((R)) production by an endophytic fungus (Stierle et al., 1993), it is possible that a number of the agents now used as leads to treatments of diseases in man, are not produced by the plant or invertebrate host from which they were first isolated and identified. They are probably the product of a microbe in, on or around the macro...

Do orchid bees sting? Female orchid bees, like the rest of the aculate Hymenoptera, have a sting apparatus, which evolved from modified ovipositor structures. Although quite painful, people rarely get stung by orchid bees, mainly because orchid bees are solitary and do not aggressively defend their nests. Also, most researchers work with stingless males, which can be easily lured to synthetic c...
