Reef-building corals are the framework builders for coral reefs and a key player in the coral reef ecosystem. They are the animals that form the foundation of Virgin Islands coral reefs which provide protection from the open ocean, are an economic resource in terms of tourism and fisheries, are the source of chemical compounds of biomedical importance, and provide great natural beauty. Due to b...
متن کاملClimate and life-history evolution in evening primroses (Oenothera, Onagraceae): a phylogenetic comparative analysis.
Evolutionary ecologists have long sought to understand the conditions under which perennial (iteroparous) versus annual (semelparous) plant life histories are favored. We evaluated the idea that aridity and variation in the length of droughts should favor the evolution of an annual life history, both by decreasing adult survival and by increasing the potential for high seedling survival via red...
متن کاملPhylogenetic relationships of cyphelloid homobasidiomycetes.
The homobasidiomycetes includes the mushroom-forming fungi. Members of the homobasidiomycetes produce the largest, most complex fruiting bodies in the fungi, such as gilled mushrooms ("agarics"), boletes, polypores, and puffballs. The homobasidiomycetes also includes species that produce minute, cup- or tube-shaped "cyphelloid" fruiting bodies, that rarely exceed 1-2 mm diameter. The goal of th...
متن کاملPhylogenetic Relationships in Solanum Section Androceras (Solanaceae)
The Leptostemonum clade of Solanum contains approximately 350–450 species, including the cultivated eggplant, S. melongena . This clade is characterized by the presence of prickles and apically attenuate anthers. Solanum section Androceras , the focus of this study, is a group of ca. 12 species belonging to the Leptostemonum clade. This section is unusual in the genus because of its mostly nort...
