  • 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?
  • analysis of the audio files revealed clear daily acoustic activity cycles in each pond

      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.
  • Publication: Jack A. Greenhalgh, et al., Diel variation in insect-dominated temperate pond soundscapes and guidelines for survey design, Freshwater Biology (2023). DOI: 10.1111/fwb.14092.

Sean Nash liked it
  • Butterflyfishes, which are facultative corallivores in this region, have even been found to prefer SCTLD-infected coral

      Some species like the infected coral Maybe it has different properties or something

    You know, there are repositories of publicly available image/video data from coral reef surveys.... somewhere online. They make them available for people to devise creative ways of pulling data out of such raw material. Might be something to look into.
