      The article does not go into any more depth about the behavioural differences the two birds have. I wish it did.

  • Although this weekend’s storm didn’t appear to take out any satellites, it may shorten some of their life spans.

      I just find it interesting that these solar storms effect satellites

  • Nature's 3D printer: Bristle worms form bristles piece by piece
  • The Raible group is currently working on improving the resolution of the observation in order to reveal even more details about bristle biogenesis.

      How did they figure out what caused the volcanos to erupt? Can you see how a specific volcano erupted based off of that?
  • Development of buoyancy overpressure at the top of a magma layer
  • Rayleigh-Taylor instabilities develop naturally whenever buoyant magma layers form.

HSR-2025 environmental fish behavioralscience biology dam

shared by Kylie John on 13 May 24 - No Cached
  • When the GD, the first dam across the mainstream of the Yangtze River, was built in the 1970s, the Chinese government explicitly demanded that the dam consider the conservation of fish.
  • Dams can harm migratory fish by disrupting their life cycles and then causing population extinctions.

      Is it possible to give the fish a different area to migrate to and from?
  • We divide the species population into spawning stock (spawners), which are sexually mature adults participating in the current year’s breeding, and recruitment stock, which includes larvae, juveniles, and subadults that have not reached the reproductive age and sexually immature adults/post-spawners that do not participate in the current year’s breeding.

  • The sixth misjudgment concerns the assertion that fishways are unnecessary in dams. The 1982 GD-FRP suggested that fishways were not needed for the Chinese sturgeon (14). The TGD, built in 1993, followed this idea and did not include fishways.
  • This study has certain limitations, such as the need for larger sample sizes of fish to improve the accuracy of the precision of fish life cycle models.

  • The environmental impacts of such actions were potentially devastating in retrospect. And ultimately, they had little influence on the long-term prevalence of plague.

  • “The challenge that I see right now on U.S. farms is a virus getting into hogs,” Osterholm says. Pigs carry receptors similar to the ones found in both humans and birds, making swine a hog-heaven for bird flus that have potential to become a pandemic.

      How come pigs have similar receptors as us
