Yet again, students from the Puerto Williams School who participate in the Omora Workshop on Natural History have taken first place in the regional science fair, sponsored by Explora-CONICYT. This year, the Omora-Puerto Williams team was represented by two groups from primary and high school. The first team, including Carlos Saavedra and Francisco Olivares, won FIRST PRIZE in the elementary student category. These students were led by Tamara Contador, a Ph.D. student in Biology from the University of North Texas and the Institute of Ecology and Biodiversity, and teacher Maria Anguita. They presented their work on Richness and abundance of freshwater invertebrates in submerged rocky and wood habitat of the Ukika River, Navarino Island, Cape Horn Biosphere Reserve (55º S).
