Fresh groundwater resources in coastal regions are vital for modern society, but are under considerable pressure due to population growth, seasonal peaks in demand, pollution and climate change. In recent years, interest in offshore freshened groundwater (OFG) has surged, as potential resource for addressing these challenges. Recent studies have documented OFG occurrences on many continental margins and islands, with global vo...

Animal models and clinical studies have linked the innate and adaptive immune system to the pathology of Parkinson’s disease (PD). Despite such progress, the specific immune responses that influence disease progression have eluded investigators. Herein, we assessed relationships between T cell phenotype and function with PD progression. Peripheral blood lymphocytes from two separate cohorts, a discovery cohort and a validation...

We investigated the community composition and the relative size‐shape distribution of bacterial assemblages in deep transparent lakes, where bacteria may be affected by harmful ultraviolet radiation (UVR). Summer samples of the euphotic zones of nine ultraoligotrophic lakes located in different drainage basins between 40°27' and 42°49'S in the North Andean Patagonia were analyzed for relative diversity by denaturating gradient...

We studied the vertical distribution of two mixotrophic ciliates, Ophrydium naumanni and Stentor araucanus in two contrasting summer seasons (strong vs. mild windy years) to determine whether differences in vertical mixing affect their success by changes in light availability for their endosymbiotic algae. Field experiments were done to evaluate the effect of light climate on the photosynthetic efficiency. To test for a potent...

Stentor araucanus is a mixotrophic ciliate that, in Andean lakes, inhabits the upper epilimnetic levels, which are commonly avoided by other planktonic organisms. This freshwater heterotrich has dark pigmented cortical granules and lives autotrophically with endosymbiotic algae. The effect of photosynthetically active radiation (PAR) and ultraviolet (UV)‐B radiation on primary production was analyzed during summer 2003–2004 in...
