| Environmental conditions can affect lichen morphology, physiology and chemistry. Some functional traits; like thickness of thallus layers, photosystems condition, and presence of photoprotective and antioxidant compounds are key to colonizing new sites, and can change depending on light and moisture availability. In the present study, we compared the morphology, physiology and chemistry of the native Chilean lichen Pseudocyphellaria flavicans from two Coastal populations (Nahuelbuta and Contulmo, Araucanía district), and one Andean population (Ralco, Bío-Bío district). Ralco is a more closed secondary forest, and can show dryer periods compared to Nahuelbuta and Contulmo. We found differences in thalli anatomy between populations. Ralco individuals had... |

| Twining in some Convolvulaceae can be induced by leaf damage and jasmonic acid application. This induced response is believed to reduce the likelihood of future leaf damage and it is limited by drought. This response has been detected in the Convolvulaceae family using artificial damage. The mechanisms and ecological implications of this response are still unknown. In this study was tested if the induced twining requires a threshold level and if it is induced by volatiles and/or by snail damage. Three separated greenhouse experiments were conducted in order to test the induced twining in Ipomoea purpurea (Convolvulaceae) by applying different levels of artificial damage (0, 1, 5, 10 perforations to the leaves), volatiles (ground leaves) and natural damage... |
