A research station studying one of these ecosystems operated by the Smithsonian has conducted a census every 5 years since 1980 on Barro Colorado (10[1])Island. LAI decreases when adjacent organisms in these ecosystems maintain a gap in a phenomenon called “shyness.” Specialist enemies of a type of organism in these ecosystems are thought to facilitate their biodiversity according to the Janzen–Connell hypothesis. (10[1])Within these ecosystems, processes by saproxylic organisms are the main contributors to nutrient cycling. (-5[1])Bridge-forming lianas in these ecosystems (10[1])can be infected by the holoparasitic (10[1])genus Rafflesia. (-5[1])Mycorrhizae (10[1])networks often form under the “floors” (10[1])of these ecosystems, (10[1])where decomposers feed on detritus like leaves. (10[1])For 10 points, name these ecosystems whose canopy is formed by trees. ■END■ (10[2])
