Neotropical primary productivity affects biomass of the leaf-litter herpetofaunal assemblage
Soil fertility and plant productivity are known to vary across the Amazon Basin partially as a function of geomorphology and age of soils. Using data on herpetofaunal abundance collected from 5 A - 5 m and 6 A - 6 m plots in mature tropical forests, we tested whether variation in community biomass o...
