| Current marsh pollution has dramatic, negative effects on sea anemone’s survival Posted: 07 Jan 2022 01:46 PM PST The starlet sea anemone Nematostella's growth, development, and feeding ability are drastically impacted by present levels of common pollutants found in one of its native habitats, the U.S. East Coast. |
| Bioenergy sorghum’s roots can replenish carbon in soil Posted: 07 Jan 2022 01:46 PM PST The world faces an increasing amount of carbon dioxide in the atmosphere and a shortage of carbon in the soil. However, bioenergy sorghum can provide meaningful relief from both problems, according to a new study. |
| Tipping point in Humboldt Current off Peru leads to species shift Posted: 07 Jan 2022 09:14 AM PST Fundamental changes in the ocean, such as warming, acidification or oxygen depletion, may have significant consequences for the composition of fish stocks, including the displacement of individual species. Researchers have reconstructed environmental conditions of the warm period 125,000 years ago (Eemian interglacial) using sediment samples from the Humboldt Current System off Peru. They were able to show that, at warmer temperatures, mainly smaller, goby-like fish species became dominant and pushed back important food fish such as the anchovy (Engraulis ringens). The trend is independent of fishing pressure and fisheries management. |
