I'm writing my cell biology paper on chromatophore and different morphs a boas like t- albinos, hypomelanism, etc.. anyways i have one scientific journal on this subject but i'm required to have 2. If anybody has any ideas where i can get a scientific journal let me no fast! if not i will only have one primary literature source and well have to use books and regular internet sites. thanks [img]modules/Forum/images/smiles/icon_confused.gif[/img]

Yo,

I'm looking for you right now. Try some of the online library catalogs at major universities. Most of them are pretty good and have actual articles reproduced online. Many of them are restricted which is why I'm looking in the sources I have access too.

If you can be more specific about what you want, I'll look further. Realize I know exactly nothing about biology, animology or any other ology so go easy with the lingo.

John

Retinal photoreceptors and visual pigments in Boa constrictor imperator
Arnold J. Sillman, Jacqueline L. Johnson, Ellis R. Loew
Journal of Experimental Zoology
Volume: 290, Issue: 4, Date: 1 September 2001, Pages: 359-365
Abstract PDF Full Text (Size: 381K) Score: 0.83

Abstract: (basically one species morphed to hunt better)

The photoreceptors of Boa constrictor, a boid snake of the subfamily Boinae, were examined with scanning electron microscopy and microspectrophotometry. The retina of B. constrictor is duplex but highly dominated by rods, cones comprising 11% of the photoreceptor population. The rather tightly packed rods have relatively long outer segments with proximal ends that are somewhat tapered. There are two morphologically distinct, single cones. The most common cone by far has a large inner segment and a relatively stout outer segment. The second cone, seen only infrequently, has a substantially smaller inner segment and a finer outer segment. The visual pigments of B. constrictor are virtually identical to those of the pythonine boid, Python regius. Three different visual pigments are present, all based on vitamin A1. The visual pigment of the rods has a wavelength of peak absorbance (max) at 495 ± 2 nm. The visual pigment of the more common, large cone has a max at 549 ± 1 nm. The small, rare cone contains a visual pigment with max at 357 ± 2 nm, providing the snake with sensitivity in the ultraviolet. We suggest that B. constrictor might employ UV sensitivity to locate conspecifics and/or to improve hunting efficiency. The data indicate that wavelength discrimination above 430 nm would not be possible without some input from the rods. J. Exp. Zool. 290:359-365, 2001. © 2001 Wiley-Liss, Inc.
