Talk:Spiders and scorpions
From Comparative Physiology of Vision
Contents |
Comments by Mike
Looks great folks. Here are a few general comments and things you might want to address. Expand a bit on how spiders use multiple eyes and segregate function between them. Contrast that with our own eyes where we have two that have the same function. For example, how would a jumping spider use all of its eyes to catch its prey? Love the telephoto lens stuff. Can spiders accommodate however? How can they see things far away and close? I thought I read once that spiders can actually shift their retina to compensate for their lack of lens accommodation. Is this true? How do they use polarized light to navigate? Why would they need it (could it be that they are extremely near sighted?) Can you find anything interesting about vision of net casting spiders?
Final Weekend Discussion
I added some of the stuff to the wiki that Mike was talking about. Specifically the moving of the retinas. I put it under motion detection for now, but feel free to move it or combine it with something else. Another thing we need to figure out still is questions. And if possible we should get them up by tomorrow (Sunday) to give people a chance to look over them when studying. Should we have a scorpion specific question or just 3 more general questions? I'll get started on thinking about a scorpion specific question if we can only come up with 2 more general ones. --Vartim18 14:52, 3 December 2011 (PST)
hey tim I am working on a section about the anterior median eyes in general and will be talking about the moving of the retinas in there, so thanks for your input on it! I think that should be the subject of one of the questions. How about everyone comes up with one question and then we can decide on the 3 to use? Sign yo name if you read this. --Culnic11 12:27, 4 December 2011 (PST)
I'm sure you all saw the e-mail, but it turns out that we won't be answering the questions until after the weekend and he'd like us to keep polishing up the page. Regardless, everyone thinking of a question sounds fine. I'm going to address accommodation in unique optics section along with retinal tiering. Also, it looks like some additions to the color section were undone? Or maybe I never posted properly, I will check this when I get to my home computer.Norand13
Starting the Page
Hey all I just wanted to let you know that I started the page by adding a Table of Contents with the different things we will need to be working on during this project. I only put those up to get the ball rolling so obviously feel free to modify it as we go. I also wanted to get the discussion page up and running so we can use it during the project to communicate. For those new to wikis, please remember to tag your name and the time/date when you posted it when discussing here and if you want to reply to something all you need to do is type right underneath where you want to reply and mark it with a ":" without the quotations. This will indent it once. If you need to reply to a reply just add one more indent than the previous one. --Vartim18 19:48, 14 November 2011 (PST)
Norand13 16:43, 26 November 2011 (PST)Good articles, reading through them now. Has anyone started writing out a section? How do we plan on dividing the work load? I'd like to get started writing/publishing tomorrow if I can. I've been looking over materials most related to color/motion. I talked to Alex before break, but I don't think I know Taylor or Evan so hopefully we can all find each other this week.

Literature Resources
Lets put our resources here! --Culnic11 16:01, 15 November 2011 (PST)
Not a fact resource, but Thomas Shahan's photography of jumping spiders is super awesome: http://www.flickr.com/photos/opoterser/ --Staale18 20:33, 29 November 2011 (PST)

hi Greenea 16:27, 15 November 2011 (PST)
Another interesting article on jumping spiders. Sure are a lot on that species. http://www.springerlink.com/content/l21657h60216x834/
