Hi all,
While there is a wealth of information out there about morphometrics, I'm
having a difficult time at the most basic level - trying to decide what
are the most appropriate methods for my questions. I am starting from
square one and I don't have anyone to ask these most basic questions to,
nor can I seem to find answers in the literature. Please forgive the
simple questions, but I would be most grateful for any advice.
I am interested in studying the influences of morphology on the behavior
(reproductive competition and swimming performance) of horseshoe crabs.
Initially I took simple measurements by hand, but have realized that the
variation in size and shape is much more complex than I had realized.
Thus, I am trying to decide if photographing the animals and using image
analysis is appropriate, or if I should be using a 3D digitizer (like
microscribe).
What are the limits of image analysis? There aren't that many flat parts
of a horseshoe crab, would this approach even work?
Give that they are expensive (and I'm a grad student with $0 in funding),
under what circumstances would one benefit from using a 3D digitizer?
Thank you in advance for any help!
-Matt
