Paraquat tolerance and alteration of internal gill structure of Scinax nasica tadpoles (Anura: Hylidae)

Paraquat acute tolerance, and histological and ultrastructural response analysis of gills were evaluated in Scinax nasica tadpoles at stages 25-26. The treated tadpoles were able to survive with a mortality rate similar to the controls in media containing 6.48 to 10.80 mg PQ/L. At 18.00 mg PQ/L surv...
