What do deep-sea crustaceans munch on? A new study titled "A deep-sea isopod that consumes Sargassum sinking from the ocean's surface," published in the journal Proceedings of the Royal Society B: Biological Sciences, sheds light on a remarkable isopod species named Bathyopsurus nybelini, a deep-sea isopod that consumes Sargassum sinking from the ocean's surface. https://phys.org/news/2024-09-crustacean-food-source-deep-ocean.html Plants & Animals Wed, 11 Sep 2024 12:05:05 EDT news645275102 Researchers at the University of Nevada, Reno have completed one of the most extensive river resilience studies, examining how river ecosystems recover following floods. They developed a novel modeling approach that used data from oxygen sensors placed in rivers to estimate daily growth in aquatic plants and algae. The researchers then modeled the algal and plant biomass in 143 rivers across the contiguous U.S. to quantify what magnitude of flooding disturbs the biomass and how long the rivers take to recover from floods. https://phys.org/news/2024-02-river-resiliency.html Ecology Fri, 16 Feb 2024 09:25:24 EST news627297916 A study led by Simon Fraser University researchers finds that mining companies are staking claims on future salmon habitats as glaciers retreat. https://phys.org/news/2023-11-industry-salmon-rivers-glaciers.html Plants & Animals Fri, 24 Nov 2023 09:43:08 EST news620041385 As any gardener or farmer can tell you, nitrogen and phosphorus are chemical elements found in soils and fertilizers that plants need to grow. They also know different ratios of nitrogen and phosphorus are ideal or detrimental for different types of plants and crops. https://phys.org/news/2022-07-nutrient-imbalance-flathead-lake.html Ecology Tue, 12 Jul 2022 14:27:04 EDT news576854821 Invasive species cause biodiversity loss and about $120 billion in annual damages in the U.S. alone. Despite plentiful evidence that invasive species can change food webs, how invaders disrupt food webs and native species over time has remained unclear. https://phys.org/news/2021-11-montana-lake-reveals-invasive-species.html Plants & Animals Thu, 04 Nov 2021 15:54:00 EDT news555260037 Glaciers are retreating in Glacier National Park and across the globe due to climate change. Researchers have long predicted that the shrinkage and disappearance of glaciers will reduce biodiversity in mountain ecosystems as species that live in habitats influenced by glacier meltwater are lost. https://phys.org/news/2020-05-persistence-meltwater-biodiversity-glacier-loss.html Earth Sciences Mon, 18 May 2020 15:00:08 EDT news509009619 The middle of the Earth's oceans are filled with vast systems of rotating currents known as subtropical gyres. These regions occupy 40% of the Earth's surface and have long been considered remarkably stable biological deserts, with little variation in chemical makeup or the nutrients needed to sustain life. https://phys.org/news/2019-08-uncover-ocean-iron-mystery.html Earth Sciences Fri, 30 Aug 2019 03:39:53 EDT news486355182 Stormwater retention ponds, a ubiquitous feature in developed landscapes worldwide, are not a significant source of climate-warming nitrous oxide (N2O) emissions, a new Duke University-led study finds. https://phys.org/news/2018-07-stormwater-ponds-major-source-greenhouse.html Environment Mon, 09 Jul 2018 16:25:52 EDT news450372341 New research by scientists at the University of Montana's Flathead Lake Biological Station has documented the first example of freshwater consumers using ancient methane-derived carbon and the most extensive example of a methane-derived carbon contribution to a river ecosystem. https://phys.org/news/2016-11-document-ancient-methane-derived-carbon-stoneflies.html Environment Thu, 10 Nov 2016 15:58:10 EST news398015882
