  • American Bullfrog - Lithobates catesbeianus - California Herps
    American Bullfrogs are voracious eaters that can impact native species, including threatened species like this Arroyo Toad and this Two-striped Gartersnake which were found in the belly of a large adult bullfrog in San Diego County The snake was dead, but the toad was alive When put back in the creek, it hopped away
  • UNDERSTANDING AND MANAGING THE IMPACT OF INVASIVE AMERICAN BULLFROGS . . .
    Biologists have identified invasive species as the most common cause of species extinctions over the past 500 years, through both direct and indirect interactions Invasive American Bullfrogs (Lithobates catesbeianus) are a threat to native species in riparian ecosystems around the world

  • Variation in Dietary Ecology of Two Invasive American Bullfrog . . .
    ABSTRACT: Invasive American Bullfrogs (Lithobates catesbeianus) are a threat to native species in riparian ecosystems worldwide They are indiscriminate predators consuming both vertebrate and invertebrate prey, negatively affecting biodiversity
  • Variation in dietary ecology of two invasive American Bullfrog . . .
    This is the first study to analyze dietary variation from contemporary populations of invasive L catesbeianus occupying different watersheds in Southern California, an area where their invasion presents acute conservation challenges
  • American Bullfrog | National Invasive Species Information Center
    The American bullfrog and brown tree snake have collectively caused $16 3bn in global damage since 1986 In addition to ecological harm, the invasive pair have ruined farm crops and triggered costly power outages

    The American Bullfrog is a harmful non-native invasive species in California that spreads disease and eats native wildlife The frogs are imported into the state by the millions and cause huge ecological damage to the state’s wildlife and ecosystems
  • Variation in Dietary Ecology of Two Invasive American Bullfrog (
    This is the first study to analyze dietary variation from contemporary populations of invasive L catesbeianus occupying different watersheds in Southern California, an area where their invasion presents acute conservation challenges
  • ERSS - American Bullfrog (Lithobates catesbeianus)
    In such environments bullfrogs are expected to have high attack rates (the attack rate is a measure of bullfrog search efficiency, specifically the length of shoreline that is kept clear of prey items by a bullfrog in a given time interval)
