Heliconias & Leaf Beetles: Making the Connection

[ARIE 2024] Teacher researchers examined the relationship between Heliconia plants and leaf beetles in the Napo-Sucusari Biological Reserve, in the Peruvian Amazon. They found that larger Heliconia patches tend to support more beetles, and that Heliconia flowering patterns vary across colonies. These insights add to our understanding of tropical plant-animal interactions and demonstrate the ecological role of Heliconia as a host species of diverse insects in this ecosystem.

Tiger Beetles on the Move: Teachers Develop New Monitoring Protocol

[ARIE 2024] Our teacher research team conducted the first study of tiger beetles in the Napo-Sucusari Biological Reserve in northeastern Peru. They used mark-recapture methods to estimate their population size, applying a technique called the Lincoln-Petersen Index. They also tagged beetles to track their movements using GPS and looked for mites that attach to them. These mites could help us learn more about how the beetles age and when different sexes and species emerge.
