  1. Postdoctoral fellow sought for conservation genetic study of an endangered Pacific island bird. The yayaguak (Mariana swiftlet, Aerodramus bartschi) is a small cave-dwelling swiftlet from the Mariana Islands now found on only 4 islands, and is restricted to 3 caves on Guam. A molecular genetic study of the species is needed to understand the level of genetic isolation among different cave colonies and evaluate evidence of inbreeding. The successful candidate will sequence the genomes of 100-200 individual birds from multiple caves to assess genetic relationships and diversity. In addition, we wish to develop and validate low-impact genetic mark-recapture methods for monitoring swiftlet populations. The candidate will develop a high throughput approach (e.g., ddRAD) to identify individuals from feathers collected below roosting sites and assist in developing models to translate this genetic sampling approach into tools for estimating abundance, survival, recruitment, and gene flow. This genetic approach will be compared with on-going field studies of mark-recapture banding, radio telemetry tracking, and productivity to validate results. This position is particularly valuable to those interested in combining molecular genetic skills with direct conservation applications of research, and the candidate will work with land managers to help them understand the results of their research. Required qualifications include: a PhD in population genetics, conservation biology, integrative biology, or equivalent field; strong communication (verbal and written) and organizational skills; positive attitude and desire to work as part of a diverse research team; expertise in genomics and its applications in ecological and conservation studies; experience generating and analyzing large datasets, including whole genome sequencing and other methods such as RAD sequencing. Additional skills desired include fluency in R and Python/Perl. Funding is for 1 year with a salary of ~$69,000/yr (depending on experience). Laboratory work will be conducted in the USGS Pacific Island Ecosystems Research Center’s molecular laboratory on Hawai‘i Island, but partial remote work during the fellowship is possible. Preferred candidates can start by early summer 2024. To apply, send a cover letter (2 pages max), a CV, and names and contact information of three references to Eben Paxton, Research Ecologist, USGS Pacific Island Ecosystems Research Center (epaxton@usgs.gov).
  2. Bird bander with molecular genetic lab experience sought for avian disease dynamics study in Hawaii. Avian malaria is driving multiple species of Hawaiian forest birds toward extinction and research is needed to understand how birds are affected by the parasite and how the birds are evolving in response. This study seeks to understand the effects of malaria on survival in the Hawaii Amakihi using a mark-recapture approach and evaluating the influence of multiple factors including condition, physiology, genomics, and gut microbiomes. A key goal is to develop strategies for managing disease in wild populations of Hawaiian honeycreepers to prevent extinction. This is a unique opportunity to work in Hawai’i Volcanoes National Park, contributing to a multi-disciplinary study focused on gathering information important for the conservation of Hawaiian forest birds. Work will include operating mist nets to capture and band Hawaiian forest birds; sampling blood, microbiomes, and other biological material; mosquito trapping; and molecular genetic lab work including DNA extraction, PCR, qPCR, and library prep for genomic sequencing. Experience mist netting for passerines required and experience with genetic lab work or equivalent strongly desired. We are looking for people with the relevant skills willing to commit to a 6-month period, tentatively scheduled from March/April through September/October 2024. Compensation is $2,610/month + free housing provided at Hawaii Volcanoes National Park. To apply, please send a single PDF including a brief cover letter (1-2 pages) highlighting relevant experience and interests, a resume, and the name, address, phone number, and email address of at least 3 references to Eben Paxton, USGS Pacific Island Ecosystems Research Center, epaxton@usgs.gov.
  3. I am looking for hummingbird, band size X, banding equipment. Especially pliers for x-small size bands. Needed for a study of Mariana Swifltets in Guam. Looking to buy (ideally) or borrow. Mahalo!
