The U.S. Geological Survey is seeking a Hawaiʻi-Pacific Islands CESU partner to study mosquito movement and food-web relationships using stable isotope analysis. - Government buyer: U.S. Department of the Interior, U.S. Geological Survey (USGS); no specific office is identified. - Opportunity: One cooperative agreement for a one-year research project, with funding up to $49,994. - Research requested: Analyze carbon-13, nitrogen-15, and hydrogen-2 isotope ratios in Culex egg rafts and adult mosquitoes collected in the Hakalau and Lapahoehoe areas; develop a Culex isoscape and investigate mosquito invasion pathways into Hakalau Forest National Wildlife Refuge. - Pilot study: Connect native flowering trees, native bird blood, and mosquito tissues to explore avian malaria food-web dynamics. - Deliverables: A curated isotope dataset released through USGS processes, a presentation at the Hawaiʻi Conservation Conference, and a peer-reviewed paper. - Notable requirements: The recipient must be a participating partner of the Hawaiʻi-Pacific Islands Cooperative Ecosystem Studies Unit (CESU). Cost sharing is not required; CESU indirect costs are capped at 17.5%. - OEMs and vendors: None are named; this is a research services opportunity, not a commercial product purchase.
Description
The U.S. Geological Survey is offering a cooperative agreement to an eligible participating partner of the Hawaiʻi-Pacific Islands Cooperative Ecosystem Studies Unit. The project will characterize stable isotope ratios in mosquito egg rafts and adult mosquitoes collected across Hakalau and Lapahapahoehoe, and investigate mosquito invasion pathways into Hakalau Forest National Wildlife Refuge. Work also includes a pilot study connecting native flowering trees, native bird blood, and mosquito tissues to explore avian malaria food-web dynamics. Expected outputs include a curated isotope dataset, conference presentation, and peer-reviewed publication.
