In May, Dr. Goodman assisted a group of ecologists working on a unique island system in Great Abaco, Bahamas. For 10 days, she and Amber Wright of University of Hawaii caught, marked, and measured Anolis sagrei lizards derived from populations introduced to 16 tiny islands two years ago. These islands will be compared to 16 additional islands that did not receive lizard introductions to determine the impact of “top down” predator effects on these ecosystems. Plant growth and invertebrate populations are being monitored by ecologists Jonah Piovia-Scott, Louie Yang, and David Spiller. This island system is also being used to determine the impact of “bottom up” effects of resource subsidies, in the form of hundreds of pounds of seaweed delivered to 16 of the 32 islands.
