Ecological Costs and Benefits of Defenses in Nectar
The nectar of many plant species contains defensive compounds that have been hypothesized to benefit plants through a variety of mechanisms. However, the relationship between nectar defenses and plant fitness has not been established for any species. We experimentally manipulated gelsemine, the principal alkaloid of Carolina jessamine (Gelsemium sempervirens), in nectar to determine its effect ...
متن کاملPredator learning differences affect the survival of chemically defended prey
http://dx.doi.org/10.1016/j.anbehav.2016.11.029 0003-3472/© 2016 Published by Elsevier Ltd on beha Prey animals that possess chemical defences often advertise their unprofitability to predators by a distinctive and conspicuous visual appearance known as aposematism. However, not all chemically defended species are conspicuous, and some are nearly cryptic. Differences in predator community compo...
متن کاملNew prostaglandins from the chemically defended soft coral Plexaura nina.
Three new prostaglandins were isolated as minor constituents of the organic extract from the Caribbean soft coral Plexaura nina. The structures of the new natural products were established by means of spectral data analysis, including 2D NMR experiments. The unpalatability of the lipid extract of the coral and the defensive role of the major prostaglandin metabolites were determined by laborato...
متن کاملThe ecological significance of toxic nectar
Although plant-herbivore and plant-pollinator interactions have traditionally been studied separately, many traits are simultaneously under selection by both herbivores and pollinators. For example, secondary compounds commonly associated with herbivore defense have been found in the nectar of many plant species, and many plants produce nectar that is toxic or repellent to some floral visitors....
