| Summary: | The green iguana (Iguana iguana) is an herbivorous lizard native to South America and is invasive in south Florida. The severe weather in January 2010 negatively impacted many species and significantly reduced the green iguana population, specifically adult females and juveniles of both sexes. Fifteen adult iguanas from two locations in Palm Beach County were tagged and had blood drawn for blood chemistry and HPLC steroid hormone analysis. Individuals were tracked for home range/territory analysis and behavioral observations. Blood chemistry values of cold-stunned individuals showed abnormal values similar to those reported in cold-stunned sea turtles. Territoriality and breeding behaviors, including nesting and head-bob displays, decreased or ceased during the following months. Steroid hormone concentrations were detected by HPLC and were not consistent with results from RIA studies in the literature. | |
