Thousands of new microbes discovered living on freshwater fish skin and guts Researchers have found that wild freshwater fish carry microbial communities that closely mirror their evolutionary relationships, with the strongest signal appearing on their skin. This discovery means that fish can be a powerful model for tracking long-term host-microbe evolution in environments constantly shaped by surrounding water. Counting fish microbes Across 121 species, the survey found that skin and gut microbes sorted themselves by host lineage. Working from that sweep of samples, biologist Zhenxin Fan at Sichuan University (SCU) helped assemble 705 microbial genomes. Fan and colleagues discovered that most assembled genomes were unknown, meaning wild fish still hold microbial life scientists have not named. That catalog also included 3,271 viral groups, so the story quickly moved beyond bacteria alone. Skin keeps score On the fish surface, the evolutionary pattern came through even more clearly than it did inside the gut. That outside layer matters because fish skin is coated with protective mucus that traps microbes and carries immune defenses. Each species likely filters that exposed community in its own way, while water contact keeps the skin under constant ecological pressure. The result suggests that a fish’s outer surface may preserve ancestry more faithfully than the better-known world inside the intestine...

Conservationists alarmed by new report into New Zealand's freshwater Conservation advocates say a [https://www.rnz.co.nz/news/national/591849/sobering-reading-waterways-worsening-around-the-country-report-reveals new report confirms the country's freshwater is at breaking point. The Ministry for the Environment and StatsNZ's Our Freshwater 2026 report highlighted the worsening quality of groundwater, rivers and lakes, including increasing levels of nitrates, E.coli levels breaching the legal limit, and nearly half of the country's river network being unsafe for swimming. Around half (45 percent) of the 998 groundwater monitoring sites tested had E. coli concentrations above the legal limit for drinking water on at least one occasion between 2019 and 2024, and modelling estimated 44 percent of New Zealand's total river length was unsuitable for activities like swimming due to faecal contamination. Among other indicators painting a worrying picture the report said glaciers, which acted as major freshwater reservoirs for rivers and groundwater, were rapidly retreating - decreasing 42 percent between 2005 and 2023. Invasive species were having a direct impact on native ecosystems and even hydroelectric power generation. Wetlands continued to be lost or degraded, despite only 10 percent of historical wetland areas remaining. Other issues exacerbated by climate change included rising sea levels risking saltwater contamination of coastal groundwater, increased extreme rainfall amplifying run off and erosion, landslides sending more...

Hidden Groundwater Powers Our Rivers: Our Freshwater 2026 Warns Why Early Action Matters Our Freshwater 2026 shows how central groundwater is to daily life, supplying drinking water to nearly half of New Zealanders and around 80 percent of everyday flow in many rivers. The report by the Ministry for the Environment and Stats NZ is the latest in the national environmental reporting series produced under the Environmental Reporting Act 2015. The last freshwater report was released in 2023. Our Freshwater 2026 shows how land use, climate change and more frequent extreme weather events are combining to put pressure on freshwater. The impacts of this are visible across rivers, lakes, wetlands and estuaries, and in the water many communities rely on every day. “Freshwater doesn’t operate in separate parts – it’s one connected system. Groundwater is the part we don’t see that links the whole system together,” said Dr Alison Collins, Chief Departmental Science Adviser, Ministry for the Environment. “Many rivers depend on groundwater to keep flowing day-to-day. But while it supplies rivers continuously, groundwater responds slowly to change. It behaves a bit like a longterm savings account – the system holds onto what goes in. Pollution that reaches groundwater can take years to decades to flush out. That’s why early, targeted action matters.”...

Airborne geophysical imaging of freshwater reservoir beneath the eastern margin of Great Salt Lake | Scientific Reports The Great Salt Lake (GSL), located in the eastern Great Basin of northern Utah, is the largest saltwater lake in the Western Hemisphere and a terminal lake, meaning it has no natural flow outlet1. Its water balance and salinity are driven by evaporation, precipitation, inflow from rivers (notably the Bear, Weber, and Jordan), groundwater2, and human activity. The lake is characterized by extreme evaporation, which drives the accumulation of dissolved salts and results in high to hypersaline conditions. The Great Basin consists of north-south-trending mountain ranges with deep, alluvial-filled basins in between2. To the east of the study site, the Wasatch Mountains rise to 2000 m above GSL and receive 500 to 1300 mm/year of precipitation, resulting in topographically driven groundwater flowing towards GSL3. In general, groundwater recharges in the Wasatch Mountains, flows westward, and then discharges at the playa margins. Approximately 15,000 years ago, freshwater Lake Bonneville covered the study site. Changing climatic conditions led to declining lake levels and salinization, beginning about 16,000 years ago, forming the current GSL4. Recently, upward hydraulic gradients of fresh groundwater (average conductivity of 0.091 S/m) have been observed in nested piezometers beneath the study site with a thin layer of hypersaline water...
