  • “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

    Be sure you are tagging articles when you bookmark them. I don't see any tags on this one, and I only see one on the other, "ice." Also... this is a SUPER interesting topic. However, we'd have way more than an uphill climb working with any sort of known pathogens (even potential pathogens) if we could even get our hands on them.

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

  • The previously hidden and diverse underwater acoustic world in British ponds has been revealed by a team of researchers at the University of Bristol.

      So... my immediate thought is: How cool would it be to do this here? One thing we DO have: PONDS. See if this *sounds* interesting. Get it? ;)
  • Acoustic monitoring has been shown to effectively survey birds and monkeys in rainforests, and marine mammals in the oceans. However, freshwater environments have remained largely unexplored despite their diverse soundscapes.

      BOOM. Again, "relatively unexplored" is super exciting verbiage to me. Acoustics. Hydrophones. Is this feasible? Is the equipment affordable? If not, could we borrow one? Dig into it. What are the possibilities?

      Aside from the exploratory surveys you would do just to see "what's out there" and assess what we CAN learn from listening to a pond, you could make it experimental by comparing ponds you've assessed the health of by other means. In other words, do acoustic comparisons between two ponds correlate with what you find by doing a macroinvertebrate sampling? I really LIKE the possibilities in this one!

  • Typically, a nocturnal chorus is made by aquatic insects that compete to attract mates by producing strange scratching sounds as they rub their genitals against their abdomens. During the daytime, however, aquatic plants dominate the underwater orchestra with rhythmic whining and ticking sounds produced as tiny oxygen bubbles are released by plants respiring in the hot sun.
  • Using this acoustic method, the presence of species, and a determination of ecological health, can be inferred simply by listening to the natural world without disturbing the environment or harming the plants and animals within it.

      Here is the obvious value proposition if you could work this out.
