Foraminifera

Alright folks,

I took some photographs of foraminifera that I'm studying for my thesis, thought they might be interesting!:pac:

[Edit: Mods feel free to edit the sizes]

Dunno about resizing, but there's the links for people who dont mind checking out your flickr.

Are they a bit like Phytoplankton - invertebrates? Never heard of them. Interesting!!

How many words do you normally have to do in a typical thesis?

Very similar in some ways to Phytoplankton, they're uni-cellular amoeboid protists. They make shells or 'tests' so they do, some make them out of detrital material (i.e. bits of fibres of grass etc...) and these are known as agglutinated or arenaceous forams. Then others make them out of calcium carbonate and these are known as calcareous forams. They're great because they're tests are always different between species in this regard (not only what they're made up of but the shape and morphology) and they also because forams tend to be statistically abundant. So things like detrended correspondence analysis, unconstrained cluster analysis, canonical cluster analysis etc... can be done in order to work out where abouts groups and individuals appear. They're used a lot in sea-level reconstructions.

How many words do you normally have to do in a typical thesis?

It depends, I'm doing a taught course and our word count is to be between 10,000 and 15,000 words. I know in other MSc's it can be 20,000 but generally as a rule of thumb it's somewhere in the mid-teens for a lot of courses. It's not as bad as you'd think, I mean 10,000 words isn't a whole lot but making the words 'count' so to speak can be trickier.

How many of these are in the white cliffs of dover?:eek:

A lot I'd imagine!:D

Beautiful images, as an artist I am really facinated by microscopic images/forms.

Recently bought a couple of books of prints by the german biologist Ernst Haeckel, really stunning.

I only know the basics about biology but these images are so amazing.




Mods::o Could I request a thread sticky for microscopic images, I think it would be really interesting pleez:).

Thanks very much for the compliment! I'm not much of a photographer, I did it to take my mind of the thesis for a few hours while still doing 'work'.
I was using a Leica microscope, something like this. And I used a broken pencil and a lot masking tape to fix a fully zoomed Olympus C-740 (3.2 mega pixel) camera to one of the eye pieces of the microscope. Those shots were taken at about X20 to X40 magnification. But if you've the proper equipment you can get really good shots.

Is that a yes or a no??:(

ermmmm

I'm not sure we get enough threads on the issue to warrant stickying it. And as the forum traffic isnt exactly roaring, any recent photographics threads do stay on the front page for quite sometime. If things change though, certainly it'll be considered.

presume ye guys know about this, but just in case...

some unreal images, great for wallpaper of the computer kind

are you writing your thesis from a biological or geological basis?

Great website there

Geological at the time (finished now just over a month). I was comparing the use of forams with stable isotope data for relative sea-level reconstruction studies (I needed to do a taxonomy on forams present in my samples and relative this to the vertical distribution). I did a bit on heavy metals to see if they would affect my foram assemblages.
