Plethodon: scores for white spots at different elevations
along Ball Creek road -- Coweeta Hydrologic Laboratory

Altitude Score for white spots
(feet) 0 1 2 3
2250 - - - 11
2550 - 3 5 2
2720 3 4 5 -
2850 9 4 - -
3150 6 7 - -
3780 7 4 3 -

Explanations of scores . . .

0 -- no white spots anywhere (absence of pigment on undersides does not count as white spots!
1 -- few white spots along sides
2 -- white spots along sides from front to rear legs (small individuals can have a few spots on the back also)
3 -- white spots on sides and back

Plethodon: scores for red on legs at different elevations
along Ball Creek road -- Coweeta Hydrological Laboratory

Altitude Score for red on legs
(feet) 0 1 2 3
2250 8 3 - -
2550 3 7 - -
2720 - 3 7 2
2850 - 2 6 5
3150 - 3 7 3
3780 - 5 7 2

Explanations of scores . . .

0 -- no red pigment on any leg
1 -- discontinuous spots of red on fore legs
2 -- continuous red along proximal parts of fore legs and some red on hind legs (more red on hind legs compensates for less on fore legs)
3 -- continuous red on proximal parts of all legs

Hairston's index of hybridization (hybrid index)
at different elevations along Ball Creek road
September 9, 2000


(hybrid index = score for red on legs MINUS score for white spots)
Altitude Hybrid index (score for red MINUS score for white)
(feet) 3 2 1 0 -1 -2 -3
2250 - - - - - 3 8
2550 - - - 2 6 - 2
2720 - 3 3 2 4 - -
2850 5 2 6 - - - -
3150 1 5 6 1 - - -
3780 1 2 8 3 - - -

Note that the hybrid index varies from 3 to -3.
"Pure" jordani have a score of 3 (leg score = 3, spot score = 0).
"Pure" "glutinosus" have a score of -3 (leg score = 0, spot score = 3).
