Anole species have been introduced to many places throughout the Caribbean and elsewhere (for example, Florida and Costa Rica), but relatively little research has examined the ecological impact of these invaders. Anolis carolinensis has been in the Ogasawara Islands of Japan for several decades, where it attains high population densities and has been blamed for local declines and even extinctions of native insects. It also is thought to negatively affect an endemic skink. Toda et al. report efforts to eliminate the green anole from port areas, so as to prevent them from stowing away and invading additional islands, and to reduce their population densities in other areas. They have found the most effective techniques to be putting out glue-traps designed for cockroaches (pictured here), which reduced anole densities by as much as 50% in some areas, and building Teflon-sided fences that anoles cannot climb. Efforts are continuing to eradicate these anoles and other invasive species on these islands. This paper also briefly reports a nice demographic study of the lizards, finding that some individuals could live longer than four years.
