Descrição

The Broa Microbial Observatory (BroaMO) was established at a small, shallow reservoir known as the Broa Reservoir or Lobo Reservoir (47°53’44.2”W, 22°10’58.2”S). This reservoir is dammed to meet local needs for water, energy supplies, and recreation. Due to its regional significance and proximity to some study centers in ecology and environmental management, the site has been extensively studied since the 1970s (e.g., Rocha and Matsumura-Tundisi 1976). However, it had not previously hosted a long-term microbial observatory. Sampling began on March 15, 2018, following the initial call for the establishment of observatories proposed by the μSudAqua network in late 2017. Since then, samples have been collected monthly, leading to the accumulation of extensive environmental and microbial data. The observatory has since become a training ground for newcomer students and a venue for testing new methodologies. Additionally, visiting researchers are regularly invited to participate in sampling cruises and interact with lab members. Over the years, some challenges have included maintaining sampling routines during the COVID-19 pandemic and managing sample processing, particularly when using equipment maintained by other study centers.
