Plants, Herbivores, and Parasitoids: A Model System for the Study of Tri-trophic Associations
Plants, Herbivores and Parasitoids: A Model System for the Study of Tri-Trophic Associations
Project Summary
For up-to-date information and the Tri-Tropic blog please see our project website.
All the nearly 20,000 plant species in North America are attacked by insect pests, including those in the group Hemiptera (known as the “true bugs”), which are in turn attacked by parasitoid insects in the Hymenoptera (sawflies, wasps, ants), widely used for biological control of agricultural pests. This project will unify some eight million records in 34 collections to answer how the distributions and phenologies of the plants, pests and parasitoids relate to each other, in a Tri-Trophic Databasing and imaging project – the TTD. Data from this approach will benefit basic scientific questions and practical applications in the agricultural sciences, conservation biology, ecosystem studies and climate change and biogeography research. Technological tools and methods will be introduced to graduate students, affiliated universities, and grant-sponsored students from other institutions through a short course. A data-mining and species-distribution modeling symposium at the University of California-Riverside will foster interactions between systematics and ecological researchers, and explore the TTD as a platform for instruction and inquiry.

This project will unify some three million records in 34 collections to answer how the distributions and phenologies of the plants, pests and parasitoids relate to each other, in a Tri-Trophic Databasing and imaging project – the TTD.

A few recent highlights include:
1. Many newly digitized records! At the beginning of 2013 the TTD had approximately 250,000 newly transformed insect records and 250,000 plant images completed.
2. Dissemination of information through attendance at iDigBio workshops, meetings, and two articles in the recent ZooKeys special issue, No Specimen Left Behind (http://www.pensoft.net/journals/zookeys/issue/209/).
3. An intensive, research focused, specimen level biodiversity informatics short course is in the planning stage and will be held in 2013.
4. Many supervised volunteers are utilized at participating institutions (particularly the NYBG and AMNH) for georeferencing and data collection.
5. The TTD at AMNH is offering a Research Experience for Undergraduates this fall (http://research.amnh.org/physsci/reu.html).
6. DiscoverLife, one of the TTD partners, has developed a host interaction public portal (http://www.discoverlife.org/tttcn/) and a series of highly sophisticated locality cleaning and matching services for the project.
7. One of our AMNH digitizers won an EOL Rubenstein Fellow (http://eol.org/info/52) to pursue her interest in altitude specificity in floral coloration.
8. The principle software for capturing host – insect –parasitoid data from natural history collections, Arthropod Easy Data Capture, has been open-sourced (http://sourceforge.net/projects/arthropodeasy/).
