    This is a crowd-sourced document I created for a session with high school research teachers in Washington D.C. in 2022. SAVE this document and use it to explore some of the more commonly-used model organisms for all sorts of biological research. There is a TON to explore here!

    This is a slide deck I used for a presentation to research teachers in Washington D.C. last year. I will also save a link to the crowd-sourced document we created in this session where teachers too our suggested model organisms, and then added in their suggestions as well.

A new breakthrough in understanding regeneration in a marine worm | ScienceDaily - 0 views

shared by Sean Nash on 03 Jul 24 - No Cached
  • The sea worm Platynereis dumerilii is only a few centimetres long but has a remarkable ability: in just a few days, it can regenerate entire parts of its body after an injury or amputation.

      Trevor Davids used the California blackworm, Lumbriculus variegatus, to examine the effects of titanium dioxide nanoparticles on regeneration rate. Lumbroculus is a freshwater worm and easy to care for.
  • a research team led by a CNRS scientist1 has observed that gut cells play a role in the regeneration of the intestine as well as other tissues such as muscle and epidermis
  • Even more surprising, the team found that this ability of gut cells to regenerate other tissue varies according to their location: the closer they are to the posterior end of the worm, the greater the variety of cell types they can rebuild

  • This was tracked using different markers in particular by fluorescent beads ingested by the worms.

      This is similar to what Grant Reed was trying to do with painted lady butterflies. He wanted to see the effects of ingesting plastic nanoparticles on their development and regeneration. The smart selection of fluorescent nanoparticles (which we purchased and still have) would allow the tracking of the particles using specialized microscopy.
  • Annelids, or 'segmented worms', which have only been studied in the last 20 years, are an ideal model for the study of regeneration, a process that is widespread in animals but still mysterious for scientists.
  • The research team will continue this work to determine whether cell types, other than gut cells, can play a role in regenerating a variety of cell types.
  • Journal Reference: Loïc Bideau, Zoé Velasquillo-Ramirez, Loeiza Baduel, Marianne Basso, Pascale Gilardi-Hebenstreit, Vanessa Ribes, Michel Vervoort, Eve Gazave. Variations in cell plasticity and proliferation underlie distinct modes of regeneration along the antero-posterior axis in the annelid Platynereis. Development, 2024; 151 (20) DOI: 10.1242/dev.202452

    There are elements of this study that connect to what Trevor Davids & Grant Reed were doing last year... but with a different model organism.

Dams trigger exponential population declines of migratory fish | Science Advances - 0 views

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.

  • how they provided guidance on general methods that could be applied to other animals such as decapod crustaceans.
  • indicate that responses of both go beyond those expected of mere nociceptive reflex.

      Where is the limit between a reflex and a cognitive response?
  • Sean Nash on 01 Jul 24
     
    I really like this topic, and it is one that is getting some current attention. so, we obviously cannot discern cellular-level factors with the nervous system of animals (and obviously- especially when dealing with pain response, we would have to work exclusively with invertebrates and the experimental design would have to be very well thought out. That said, behavioral studies where you have a really tight experimental design set up.... and you're recording behavioral changes... is likely feasible. If this is interesting, keep digging into pain vs. reflex studies, and also begin to look at invertebrate models that we can both successfully raise... and that have interesting behavioral responses we can readily discern in the lab.
