Impact assessment of agriculture and livestock over age, longevity and growth of populations of common toad Rhinella arenarum (anura: Bufonidae), central area of Argentina
The central area of Argentina has been greatly affected mainly due to urbanization and intensive agriculture (corn, soybean and cattle). Age, longevity and growth were determined in populations of the common toad, Rhinella arenarum, from urban and agricultural sites in the central area of Argentina....
