PM me your email and, when I get back to work next week, I can send you some of the science papers I read that got me interested and motivated if you're interested. I can send you my research publication, too, if you need a cure for insomnia. The original work by Glenn and Straight (1983 and a couple of others of theirs) documented the hemorrhagic toxin to roughly parallel the east side of I-10 between Tucson and Phx (big generalization there) with outliers/specimens all around both towns. The areas having both neurotoxin (called Mojave toxin) and hemorrhagic toxin ran right along that I-10. The hemorrhagic toxin is very specific to a smaller area within Arizona and the area with properties of both is even smaller in AZ. Throughout the rest of their range in AZ, NM, NV, CA, far southwest UT and west Texas (east of El Paso), they have a very strong neurotoxin. Lethality results from LD50 tests puts venom from diamondbacks (all hemorrhagic toxin) at roughly 3-5 micrograms of venom/kilograms of body weight. Mojave toxin LD50 tests were at a range of 0.15-0.25 micrograms of venom/kilograms of body weight.
True/funny story. I was processing vials of pure crystallized Mojave toxin in my lab one day, after getting all of the un-pure liquids off and I wasn't at the vent hood in my lab. It took me a few minutes to realize I'd been inhaling the pure, crystallized Mojave toxin. I lost feeling in my nose for three hours and had recurring outbreaks during times of hight stress due to the buildup of antibodies specific to the venom. I'd lose feeling in my nose for up to an hour. That went off/on for about 10 years.
