Ultraviolet radiation (UVR) plays a key role in several biological functions, including human health. Skin exposure to UVR is the main factor in vitamin D photoconversion. There is also evidence relating low levels of vitamin D with certain internal

During mid 2004, abrupt environmental changes including a massive die off of the dominant macrophyte Egeria densa were observed within the wetlands of Rio Cruces, a Ramsar site in southern Chile. One of the hypotheses presented to explain these chang

Daily and annual cycles of solar ultraviolet radiation were characterised at Valdivia, Chile (39.8°S), using data collected with a multichannel radiometer between January 1995 and March 1999. First, the instrument's measurements at 305 and 340 nm we
