The National Science Foundation (NSF) Graduate Research Internship 
Program (GRIP) provides NSF graduate fellows with internship 
opportunities for professional development and network expansion at 
federal facilities. This is a great way to add an applied research 
component to a dissertation/thesis, see options for research careers 
outside of academia, and make connections with the U.S. Geological 
Survey. The USGS Pacific Island Ecosystems Research Center in Hawaii 
Volcanoes National Park has two opportunities listed for potential 
interns, both of which concern the impact of invasive animals on 
Hawaiian forest communities. Project 1 looks at the impacts of these 
animals on plant communities, while Project 2 studies invasive rat 
foraging behavior to help predict impacts on bird communities. You must 
be a current NSF fellow to apply.

Project 1: Invasive animal species threaten intact Hawaiian forest 
communities by disrupting plant-pollinator mutualisms and incurring high 
levels of flower and seed predation. Removing such invaders requires 
large management funds, although the efficacy for restoring ecological 
functions to forests is yet unclear. Our objective is to advance 
understanding of how invasive animal removals affect plant community 
dynamics. USGS scientists are implementing a large-scale, replicated, 
experimental removal of invasive yellowjacket wasps, Argentine ants, and 
rats from mesic forest communities in Hawaii Volcanoes National Park. 
The successful intern will use this opportunity to lead studies on the 
response of the plant community to these removals. The successful 
candidate will work with mentors to design and implement monitoring 
and/or experiments that test plant community response to invasive animal 
removals. Possibilities include: (1) investigating the effects of 
yellowjacket removal on flower abundance and fruit set in target 
species; (2) conducting seed predation experiments to investigate the 
effects of rats on seed availability; (3) testing the effects of 
argentine ants on seed dispersal and seedling emergence; (4) conducting 
seed addition and weed removal experiments to ask how ecologically 
important plant-pollinator mutualisms and seed predation are for plant 
communities relative to other ecological factors.

Project 2: Rats have profound ecological impacts on islands due to 
depredation on native birds and other vertebrates, invertebrates, and 
plants. Black rats (Rattus rattus) occur in relatively high densities in 
mesic, montane forests of Hawaii Volcanoes National Park, where 
vegetation has been recovering following the removal of introduced 
browsing ungulates over 25 years ago. Our hypothesis is that removing 
rats and other invasive predators from these habitats will spur 
additional recovery of bird, arthropod, and plant communities. The 
overall objective is to understand how black rat foraging behavior and 
habitat use affect bird communities and otherwise impede ecosystem 
recovery in forests of varying vegetation structure and species 
composition.
