Plethodon: scores for white spots at different elevations
along Ball Creek road -- Coweeta Hydrologic Laboratory
September 16, 2000

Altitude Score for white spots
(feet) 0 1 2 3
2250 - - 1 11
2550 - 1 3 3
2720 3 4 2 1
2850 4 3 1 1
3150 7 1 2 -
3450 7 1 2 -

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
September 16, 2000

Altitude Score for red on legs
(feet) 0 1 2 3
2250 7 5 - -
2550 2 3 1 1
2720 - 6 2 2
2850 - 8 2 -
3150 - 1 4 5
3450 - 4 1 5

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

Plethodon:
Hairston's index of hybridization (hybrid index)
at different elevations along Ball Creek road
September 16, 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 - - - - 1 4 7
2550 - - 1 1 3 - 2
2720 1 1 3 3 1 1 -
2850 - 2 3 3 1 1 -
3150 4 2 3 1 - - -
3450 5 - 2 2 1 - -

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).
