A new study of the largest dam removal project in United States history on the Klamath River in Oregon and California is offering new insight into a long-running water conflict by finding that farmers and conservation groups share priorities that may help guide decision-making on future river restoration projects.

Due to human development and climate change, tidal wetland areas have been shrinking globally. A new study using 40 years of satellite data shows that this loss has been accelerating in the U.S. and that this acceleration is being increasingly driven by extreme weather events.

This work was led by Xiucheng Yang, a former UConn postdoctoral researcher and current senior research fellow at the University of Victoria, and Zhe Zhu, an associate professor and director of Global Environmental Remote Sensing (GERS) Laboratory in the Department of Natural Resources and the Environment in the College of Agriculture, Health and Natural Resources (CAHNR). The study was published in the journal Nature Communications.

Researchers developed an automated cold plasma and bubble system for dual modality function of treating food-industry wastewater and transforming into nutrient-rich liquid fertilizer for hydroponic farming. This automated electrified flow system runs on a low energy, reduced wastewater organic load while simultaneously improving plant growth, offering a scalable and promising route toward sustainable agriculture and water reuse.

Neanderthal populations in southern Europe collected shellfish throughout the year, with a marked preference for the colder months, according to a new international study led by researchers from the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB), the IsoTOPIK Lab at the University of Burgos (UBU), and the Instituto Internacional de Investigaciones Prehistóricas de Cantabria at the University of Cantabria (UC).

Intensive agriculture poses a significant threat to global biodiversity. However, one aspect of biodiversity in farmland is little studied: algae. Most people have seen algae growing in streams, lakes or the sea. However, algae have also adapted to survive in dryer, harsher conditions on land. In fact, soil algae are thought to be responsible for about 6% of the vegetation production on Earth. This led a research team at the universities of Göttingen and Kassel to investigate the algae in the surface soils of farmland. Their pilot study revealed more than 100 different algae, likely to be made up of hundreds of individual species. Unlike most other microbes, these algae showed seasonal variation in their communities. These are the first steps towards understanding the factors that determine the diversity of these important microorganisms. The results were published in the Journal Frontiers in Microbiology.
