Greater St Lucia Wetland Park (South Africa)
生态系统变化: Chromolaena odorata is reported to interfere with natural ecosystem processes in the Greater St. Lucia Wetland Park. Nesting Nile crocodiles (see Crocodylus niloticus in IUCN Red List of Threatened Species) require open, sunny, sandy areas in which to deposit their eggs. C. odorata shades and overtakes nesting sites creating fibrous root mats unsuitable for egg chamber and nest construction. As well as altering this natural habitat C. odorata produces shade resulting in colder temperatures in any nests that do get constructed, an effect that produces a female-biased sex ratio in the offspring as well as perhaps preventing embryonic development altogether (Leslie and Spotila 2001).
