Article Synopsis
- The European flat oyster, a vital part of marine ecosystems and a key economic resource, has seen its habitats drastically decline, leading to functional extinction.
- Recent studies compiled data from 1524 to 2022 to reveal past locations and extents of flat oyster fisheries and reefs, highlighting where these ecosystems once thrived.
- These datasets aim to support flat oyster restoration efforts and improve adaptive management strategies while helping recover overlooked histories of ocean ecosystem changes caused by human activities.
Article Synopsis
- The study investigates how rising temperatures due to climate change affect ecosystems, particularly freshwater food webs in high-latitude regions like Iceland and Russia.
- Researchers conducted natural experiments in 14 streams with temperature increases of up to 20°C, discovering that warmer streams had less trophic diversity and a shift towards more reliance on local (autochthonous) carbon sources.
- The findings suggest that higher temperatures lead to simpler food webs, confirming predictions about the impacts of global warming on freshwater ecosystems at large scales.
Cold plasma of ionospheric origin has recently been found to be a much larger contributor to the magnetosphere of Earth than expected. Numerous competing mechanisms have been postulated to drive ion escape to space, including heating and acceleration by wave-particle interactions and a global electrostatic field between the ionosphere and space (called the ambipolar or polarization field). Observations of heated O ions in the magnetosphere are consistent with resonant wave-particle interactions.

Non-publicly available data, including the net prices of selected drugs and their therapeutic alternatives, will play a central role in the determination of the maximum fair prices (MFPs).
Objective: To estimate price benchmarks involved in the derivation of the starting point of the CMS initial price offer for the 10 drugs selected for Medicare price negotiation.
