• Recently, the eDNA method was developed to identify organisms in various aquatic ecosystems, such as lakes/ponds, rivers, and oceans. (eurekalert.org)
• Many microorganisms play foundational roles in aquatic ecosystems, capturing the sun's energy through photosynthesis and, through their role in decomposition, releasing nutrients stored in organic tissue. (ramp-alberta.org)
• Interactions between climate change and UV radiation are having strong effects on aquatic ecosystems due to feedback between temperature, UV radiation, and greenhouse gas concentration. (rsc.org)
• This assessment addresses how our knowledge of the interactive effects of UV radiation and climate change factors on aquatic ecosystems has advanced in the past four years. (rsc.org)
• Interactions between climate change, ozone, and ultraviolet (UV) radiation are altering exposure to UV radiation in aquatic ecosystems. (rsc.org)
• 1,2 Climate change is causing the average global air temperature to rise and precipitation patterns to change, with important consequences for UV exposure in aquatic ecosystems. (rsc.org)
• Rising atmospheric CO 2 concentration induces ocean acidification and alters seawater chemistry and consequently changes UV protection provided by calcified exoskeletons in many aquatic organisms as well as UV exposure levels in aquatic ecosystems. (rsc.org)
• EPA's 1985 Guidelines for Deriving Numerical National Water Quality Criteria for the Protection of Aquatic Organisms and Their Uses (the Guidelines ) describe a process that uses information form many areas of aquatic toxicology to deriving national criteria for the protection of aquatic ecosystems. (epa.gov)
• EPA's Office of Pesticide Programs (OPP) and the Office of Water (OW) assess the effects of pesticides on aquatic ecosystems using approaches that afford a high degree of protection for aquatic life and that were developed with high quality data using rigorously peer-reviewed assessment methodologies. (epa.gov)
• Primary production plays a key role in determining aquatic community structure and function in stream ecosystems. (nps.gov)
• Aquatic macroinvertebrates play a key role in nutrient cycling in aquatic ecosystems because they are the primary processors of organic materials. (nps.gov)

(usgs.gov)
• However, relatively few of measured pesticides-atrazine, acetochlor, metolachlor, imidacloprid, fipronil, selected organophosphate insecticides, and carbendazim-were measured at levels likely to be major contributors to aquatic toxicity, according to aquatic life benchmarks and the PTI. (usgs.gov)
