Mosses growing by a fumarole in cold subantarctic conditions. A fumarole is a volcanic crack in the Earth's surface. It emits volcanic gases such as steam. Plants colonize ecological niches like this because of warmer temperatures,a water supply (condensing steam and meltwater) and a rich supply of minerals from volcanic rocks. Mosses (phylum Bryophyta) are small plants that lack true roots,woody tissue and flowers. They grow in damp places worldwide.
