A Note on the Lichen Genus Ramalina (Ramalinaceae, Ascomycota) in the Hengduan Mountains in China
On the basis of extensive field investigation and a series of herbarium specimen identifications, we present and discuss the descriptions and distribution of 22 species of Ramalina found in the Hengduan Mountains of southwestern China. In this revisionary study, representatives of the Ramalina genus, including R. americana, R. confirmata, R. dendriscoides, R. obtusata, R. pacifica, R. pentecost...
متن کاملCharacterization of enzymatic antioxidants in the lichen Ramalina lacera and their response to rehydration.
Lichens are slow-growing associations of fungi and green algae or cyanobacteria. This symbiotic association forms a common thallus that does not possess roots or a waxy cuticle and depends mainly on atmospheric input of mineral nutrients. The lifestyle of most lichens is composed of alternating periods of desiccation with low metabolic activity and hydration that induces increase in their metab...
متن کاملFirst record of the Devonian lycophyte Leclercqia from South America
A single leafy stem from the Middle or lowermost Upper Devonian Campo Chico Formation, Sierra de Perija, western Venezuela, is the first record of the important Devonian herbaceous lycophyte Leclercqia from South America, usually considered as part of western Gondwana. The seemingly cosmopolitan distribution of this genus is discussed in relation to coeval assemblages and palaeocontinental reco...
متن کاملPhylogeography of Ramalina menziesii, a widely distributed lichen-forming fungus in western North America.
The complex topography and climate history of western North America offer a setting where lineage formation, accumulation and migration have led to elevated inter- and intraspecific biodiversity in many taxa. Here, we study Ramalina menziesii, an epiphytic lichenized fungus with a range encompassing major ecosystems from Baja California to Alaska to explore the predictions of two hypotheses: (i...
متن کاملFirst record of Trichosteresis Förster (Hymenoptera: Megaspilidae) from South America.
The family Megaspilidae worldwide comprises more than 450 species in 11 genera (Dessart 2006), but the fauna of the family in South America is poorly known. For example, Dendrocerus Ratzeburg has been the only named genus reported from either Argentina (Loiácono 1998; Martinez 2003) or Brazil (Loiácono & Margaría 2002). Trichosteresis Förster is considered a monotypic genus, recorded from Europ...
