Poison frog colors are honest signals of toxicity, particularly for bird predators (ME Maan and ME Cummings; American Naturalist MS 52931)
--------------------------------------------------------------------------------------------------------------------------------------
Two datafiles:
Data_MaanCummings_2011_ AmNat52931_ByInd: toxicity data collected at the level of individual frogs
Data_MaanCummings_2011_ AmNat52931_ByPop: data collected at the level of frog population
--------------------------------------------------------------------------------------------------------------------------------------
All data collected by Martine E. Maan and Molly E. Cummings.

Data_MaanCummings_2011_ AmNat52931_ByInd
pop abbreviation of frog population (see Figure 1; SO=Solarte; BCG=Bastimentos green; BCO=Bastimentos orange; AG=Aguacate; SC=San Cristóbal; AL=Almirante; SH=Pastores; CA=Cayo Agua; PoSo=Popa South; CO=Colón;TALA=Allobates talamancae, from Bastimentos)
pop# population number (see Figure 2)
replicode code indicating whether an individual frog sample was replicated, i.e. injected into 2 mice: 1=not replicated; 2=injected twice; 3=average of the two toxicity estimates from replicates
frogid unique code for individual frogs
frogweight frog weight (in gram)
frogsvl frog snout-vent-length (in mm)
frogsex 1=male; 2=female
tox toxicity estimate (not normalised, but adjusted for dosage)
Missing data indicated by NA
