Mayumi L Arimitsu, Ph.D.

Forage fish, seabirds, predator-prey interactions, glacier-marine ecosystems, marine heatwaves, climate change

I lead research to identify factors influencing the status and trends of rare or threatened species on DOI lands, to understand the effects of glacier dynamics on coastal fjord ecosystems, and to document impacts of novel ocean climate patterns on the functioning of marine food webs. As the Pelagic Lead for the Gulf Watch Alaska long-term monitoring program I coordinate research integration across sampling programs for forage fish, marine birds, humpback whale, and killer whales.

Ground-nesting marine birds and potential for human disturbance in Glacier Bay National Park

Glacier Bay National Park and Preserve contains a diverse assemblage of marine birds that use the area for nesting, foraging and molting. The abundance and diversity of marine bird species in Glacier Bay is unmatched in the region, due in part to the geomorphic and successional characteristics that result in a wide array of habitat types (Robards and others, 2003). The opportunity for proactive ma

Spatiotemporal predictability of schooling and nonschooling prey of Pigeon Guillemots

Low spatiotemporal variability in the abundance of nonschooling prey might allow Pigeon Guillemots (Cepphus columba) to maintain the high chick provisioning rates that are characteristic of the species. We tested predictions of this hypothesis with data collected with beach seines and scuba and hydroacoustic surveys in Kachemak Bay, Alaska, during 1996–1999. Coefficients of variability were 20–211

Inventory of marine and estuarine fishes in southeast and central Alaska National Parks

As part of a national inventory program funded by the National Park Service, we conducted an inventory of marine and estuarine fishes in Glacier Bay National Park and Preserve, Wrangell-St. Elias National Park and Preserve, Sitka National Historical Park, and Klondike Gold Rush National Historical Park in 2001 and 2002. In addition, marine fish data from a previous project that focused on forage f
