the ten most outstanding new species in the world (ESF Lists Top 10 New Species), prepared by the ESF International Institute for Species Exploration (IISE). This list is released on May 23 to commemorate the birth date of Carolus Linnaeus – better known as Carl von Linnaeus -, the Swedish botanist who in the 18th century established the bases of the scientific nomenclature of living beings. This year, the world’s top 10 includes new species of amphipod crustaceans, beetles, orangutans, plants and fish, among other organisms discovered in China, Brazil, Indonesia, Japan, Australia or the Antarctic Ocean. As Quentin Wheeler, director and founder of IISE explains, “I am constantly amazed at how many new species appear and the variety of things that are discovered.” Thiolava veneris : the bacteria discovered after a volcanic eruption T. venerisis the first bacterial

species to be discovered associated with the Sweden Email List activity of Tagoro, a volcano that arose as a result of an underwater eruption in El Hierro, which took place between October 2011 and March 2012. At the time of its discovery, the new community The bacterium formed a microbial tapestry of very showy white filaments – bacterial trichomes or hair of Venus – that covered almost 2,000 square meters near the top of the Tagoro volcano, at a depth of between 129 and 132 meters, according to the images of an underwater vehicle revealed Remote Controlled Unmanned (ROV). The experts Galderic Lastras, David Amblàs, Anna Sánchez Vidal, Jaime Frigola, Antoni M. Calafat, Rut Pedrosa and Xavier Rayo, all from the GRC in Marine Geosciences, also participated in the research.from the UB, and Jesús Rivera, from the Spanish Institute of Oceanography
among others. Living in extreme environments at the bottom of the sea The underwater eruption in El Hierro substantially modified the underwater relief. Initiated at a depth of 363 meters, the eruption originated a new volcanic cone and a cone of deposits that reached more than 1,000 meters deep. This geological episode, which lasted for 138 days, also radically altered the conditions of the ecosystem on a local scale (temperature, oxygen, acidity, turbidity, nutrients, etc.). According to Miquel Canals, head of the GRC in Marine Geosciences and director of the Department of Earth and Ocean Dynamics at the UB, “most of the volcanic activity on our planet takes place at the bottom of the sea.” “Until now,” Canals points out, “most of the bacterial communities related to underwater volcanic activity had been studied in the hydrothermal vents of the mid-ocean ridges.
