  1. Biological Pollution: American Bullfrog • Voracious predators • Ability to travel long distances • High fecundity • Highly adaptable • Native to Eastern US • Largest frog in US • Introduced to SW in early 1900’s • as food source • Why is the Bullfrog considered ‘Biological Pollution’? • Rapid predation of native species • High competition as riparian predator • Highly mobile conduit for fatal disease (Chytrid fungus) • Eradication/control very expensive, and inefficient Solutions: Education/Prevention-increase awareness on issue, community outreach Containment–confine existing populations or individuals to current space Eradication–destroy populations or individuals By: Alex Lichtblau, Josh Ruddick, Emily Kaleugher Photos Courtesy of: http://i.pbase.com/u35/tmurray74/large/33517067.256_5624_RT16.jpg http://frog-shots.com/images/bullfrog_eating_treefrog_2.jpg http://www.fishpondinfo.com/photos/amphibians/bullfrogs/birdfrog2.jpg http://pages.cthome.net/fwc/RCRANGE.GIF http://redbar.web.arizona.edu/logos/blocka.html http://www.cs.arizona.edu/~clayton/evap-web/figs/B2-UA-logo.gif
