Adaptive radiations play key roles in the generation of biodiversity and biological novelty, and therefore understanding the factors that drive them remains one of the most important challenges of evolutionary biology. Although both intrinsic innovations and extrinsic ecological opportunities contribute to diversification bursts, few studies have looked at(More)
Liquid chromatography coupled with mass spectrometry is an outstanding methodology for fast analysis of phenolic compounds in biological samples. Twenty two compounds were quickly and accurately identified in the methanolic extract of the Antarctic lichen Ramalina terebrata for the first time using ultra high pressure liquid chromatography coupled with(More)

During the preparation of a revision of the genus Caloplaca (Teloschistaceae, Teloschistales) in Chile being undertaken by the second author, we found a very interesting collection of a fragile lichen that was growing tightly associated with a tiny moss species. Microscopic observations confirmed the identities of these species as Caloplaca fragillima Poelt(More)
