Antioxidants | Free Full-Text | Drought and UV Radiation Stress Tolerance in Rice Is Im... - 0 views

  • . Plant Material, Growth Conditions, and Phenotypic EvaluationWe used the rice (Oryza sativa L.) seeds of the transgenic (OxF3H) and non-transgenic Nogdong cultivars provided by the Plant Molecular Breeding Laboratory, Kyungpook National University, Korea [41]. Rice seeds were sterilized with fungicides overnight and then washed with double distilled water three times. Next, the rice seeds were soaked in water for four days in an incubator in the dark condition at 32 °C, with the water changed after each 24 h as previously reported by [41]. After soaking and successful sprouting, rice seeds were transferred to autoclaved soil and kept in the dark again for three days. After growth, the three week rice seedlings were exposed to light and kept in a greenhouse for further experimentation.

Mysterious Underwater Acoustic World of British Ponds Revealed in New Study | Current S... - 3 views

  • 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.
