Science and Products
Dr. Josh Adams and his colleagues study seabird ecology by quantifying abundance patterns associated with habitats at sea, where seabirds spend the overwhelming majority of their lives. Adams also researches breeding seabirds and employs conservation science support on land, where seabirds are obligated to nest. His group provides scientific analyses to help understand the efficacy of certain conservation practices intended to benefit the preservation and recovery of threatened seabird populations. Their results provide resource managers with information required for effective management, conservation, and restoration actions.
To support science-based decision capacity and Marine Spatial Planning (MSP) among U.S. Government resource managers, Dr. Josh Adams has partnered with the U.S. Fish and Wildlife Service, National Park Service, Bureau of Land Management, National Oceanic and Atmospheric Administration and others (including international research partners) to examine the pelagic ecology of multiple far-ranging seabirds (e.g., albatrosses and petrels).
Collision and displacement vulnerability among marine birds of the California Current System associated with offshore wind energy infrastructure
With growing climate change concerns and energy constraints, there is an increasing need for renewable energy sources within the United States and globally. Looking forward, offshore wind-energy infrastructure (OWEI) has the potential to produce a significant proportion of the power needed to reach our Nation’s renewable energy goal. Offshore wind...Adams, Josh; Kelsey, Emily C.; Felis, Jonathan J.; Pereksta, David M.
First steps for mitigating bycatch of Pink-footed Shearwaters Ardenna creatopus: Identifying overlap of foraging areas and fisheries in Chile
The Pink-footed Shearwater, Ardenna creatopus, is listed as in danger of extinction by Chile and under Annex 1 of ACAP, with an estimated global population of approximately 56,000 individuals. Incidental bycatch of this species in fisheries is thought to be an important cause in population decline (i.e. annual estimated mortality of >1000...Carle, Ryan; Felis, Jonathan J.; López, Verónica; Adams, Josh; Hodum, Peter; Beck, Jessie; Colodro, Valentina; Vega, Rodrigo; González, Andrés
Migratory routes and at-sea threats to Pink-footed Shearwaters
The Pink-footed Shearwater (Ardenna creatopus) is a seabird with a breeding range restricted to three islands in Chile and an estimated world population of approximately 56,000 breeding individuals (Muñoz 2011, Oikonos unpublished data). Due to multiple threats on breeding colonies and at-sea, Pink-footed Shearwaters are listed as Endangered by...Adams, Josh; Felis, Jonathan J.; Hodum, Peter; Colodro, Valentina; Carle, Ryan; López, Verónica
Identifying Kittlitz's Murrelet nesting habitat in North America at the landscape scale
The Kittlitz's Murrelet (Brachyramphus brevirostris) is a small, non-colonial seabird endemic to marine waters of Alaska and eastern Russia that may have experienced significant population decline in recent decades, in part because of low reproductive success and terrestrial threats. Although recent studies have shed new light on Kittlitz's...Felis, Jonathan J.; Kissling, Michelle L.; Kaler, Robb S.A.; Kenney, Leah A.; Lawonn, Matthew J.
Ashy Storm-Petrel Oceanodroma homochroa mist-netting and capture rates in the California Channel Islands, 2004–2007
The California Channel Islands (CCI) provide essential nesting habitat for a significant portion of the world’s Ashy Storm-Petrel Oceanodroma homochroa (ASSP) breeding population, but true abundance at this locality is not well known. Land-based nocturnal mistnetting has been conducted sporadically in the CCI since 1976, with variation in...Adams, Josh
Occurrence, morphometrics, and plumage variability among Leach’s Storm-Petrels Oceanodroma leucorhoa in the California Channel Islands, 1976–2015
We mist-netted and examined Leach’s Storm-Petrels Oceanodroma leucorhoa (LESP) caught during 1991–2015 at three locations in the California Channel Islands (CCI): Prince Island, Santa Barbara-Sutil islands and Scorpion Rock. Although mist-netting methods and effort varied between two study periods (1991–1995, 2004–2007 and...Adams, Josh; Carter, Harry R.; McChesney, Gerard; Whitworth, Darrell L.
Predictive mapping of seabirds, pinnipeds and cetaceans off the Pacific Coast of Washington
About this report This report supports Washington-led marine spatial planning and responsible stewardship of natural and cultural resources by the Olympic Coast National Marine Sanctuary. Washington state agencies and the sanctuary continually seek the best available science to improve management of marine uses and stewardship of resources (...Menza, Charles; Leirness, Jeffery B.; White, Tim; Winship, Arliss; Kinlan, Brian P.; Kracker, Laura; Zamon, Jeannette E.; Ballance, Lisa; Becker, Elizabeth; Forney, Karin A.; Barlow, Jay; Adams, Josh; Pereksta, David; Pearson, Scott; Pierce, John; Jeffries, Steven J.; Calambokidis, John; Douglas, Annie; Hanson, Bradford C.; Benson, Scott R.; Antrim, Liam

Pacific Continental Shelf Environmental Assessment (PaCSEA): aerial seabird and marine mammal surveys off northern California, Oregon, and Washington, 2011-2012
Marine birds and mammals comprise an important community of meso- and upper-trophic-level predators within the northern California Current System (NCCS). The NCCS is located within one of the world’s four major eastern boundary currents and is characterized by an abundant and diverse marine ecosystem fuelled seasonally by wind-driven upwelling...Adams, Josh; Felis, Jonathan J.; Mason, John W.; Takekawa, John Y.
Summer-time use of west coast U. S. National Marine Sanctuaries by migrating sooty shearwaters (Puffinus griseus)
Non-breeding sooty shearwaters are the most abundant seabird in the California Current Large Marine Ecosystem (CCLME) during boreal spring and summer months. This, combined with relatively great energy demands, reliance on patchy, shoaling prey (krill, squid, and forage fishes), and unconstrained mobility free from central-place-foraging demands—...Adams, Josh; MacLeod, Catriona; Suryan, Robert M.; Hyrenbach, K. David; Harvey, James T.
Population divergence and gene flow in an endangered and highly mobile seabird
Seabirds are highly vagile and can disperse up to thousands of kilometers, making it difficult to identify the factors that promote isolation between populations. The endemic Hawaiian petrel (Pterodroma sandwichensis) is one such species. Today it is endangered, and known to breed only on the islands of Hawaii, Maui, Lanai and Kauai. Historical...Welch, A.

Foraging segregation and genetic divergence between geographically proximate colonies of a highly mobile seabird
Foraging segregation may play an important role in the maintenance of animal diversity, and is a proposed mechanism for promoting genetic divergence within seabird species. However, little information exists regarding its presence among seabird populations. We investigated genetic and foraging divergence between two colonies of endangered Hawaiian...Wiley, Anne E.; Welch, Andreanna J.; Ostrom, P.H.; James, Helen F.; Stricker, C.A.; Fleischer, R.C.; Gandhi, H.; Adams, J.; Ainley, D.G.; Duvall, F.; Holmes, N.; Hu, D.; Judge, S.; Penniman, J.; Swindle, K.A.
