This project will engage researchers from the University of Idaho to assist with a set of analysis tasks that will improve understanding of seabird population dynamics and environmental drivers at a regional scale based on prior survey efforts that have been focused at a colony scale. Specifically, we envision the development of a population model for a couple of index species like murres and kittiwakes, including evaluation of spatial clustering of populations that co-vary, in order to: 1) asses implications of covariates with identified mechanisms and appropriate temporal (pre-breeding condition, summer, rearing, overwinter survival, etc.) and spatial scales; 2) evaluate the feasibility of combining seabirds into...

In Alaska, changes in snow, ice, and weather, have resulted in risks to human lives, infrastructure damage, threats to valuable natural resources, and disruption of hunting, fishing, and livelihoods.Leaders from the Aleutians to the Chukchi Sea came together for a series of Coastal Resilience and Adaptation Workshops, spearheaded by three Landscape Conservation Cooperatives and the Aleutian Pribilof Islands Association. Tribal leaders, resource managers, community planners, and scientists explored strategies to adapt to these unprecedented changes.The workshop series brought together 14 Organizing Partners 34 Tribes, 15 State & Federal Agencies, and a total of more than 200 participants to meet in four regional...

Partners developed a simulation model to better show how various projections associated with increased marine traffic in the Bering Sea might look in the coming decades. These simulations are able to help communities and managers better understand future patterns of traffic in the Bering Sea region as a whole, and look more specifically at possible changes in key areas of concern like the Bering Strait.Following vessel activity analysis and considering vessel type, transit routes, route timing, routing speed, and ports of call, we developed a novel agent-based, spatially-explicit, baseline model of current marine vessel traffic patterns. We then applied projections about changes in traffic volume from a report by...
The distribution and abundance of small, schooling forage fish (e.g., sandlance, capelin) in Alaska is knownfrom small-scale directed studies, but mostly inferred from incidental catches in large-scale trawl surveysthat were not designed (by gear or location) to sample forage species. In contrast, seabirds are conspicuous,highly mobile, samplers of forage fish that go to great distances (100+ km) and depths ( 200m) to locateephemeral prey with great efficiency. Thus, data on their dietary habits provides a valuable complement totraditional fisheries sampling. We propose to analyze large diet databases for three abundant seabirds(puffins, murres and kittiwakes) to: 1) characterize forage fish communities in the Gulf...
Assigning a numerical rank to an introduced species is an objective, quantifiable way to describe their relative impacts, and ranks are a valuable prioritization tool for land managers. We applied the Invasiveness Ranking System previously developed by the Alaska Natural Heritage Program to evaluate introduced species known to occur on Aleutian and Bering Sea Islands. This system uses sixteen criteria grouped into four categories to assess invasiveness: distribution, biological characteristics and dispersal ability, ecological impacts, and feasibility of control. Answers to individual questions are assigned a point value and the points are used to calculate subranks for each of the four sections. Each section is...

Activity 1. Quantify viability of corridors using temporal sampling: past, present, future. As large-scale wind patterns change, the viability of flyways in the Pacific hemisphere is likely to change. This project will evaluate the tail/headwind components for flight routes from Alaska to sites in the South Pacific (documented godwit and curlew flight tracks) by sampling 50-year timeslices to determine whether the present climatology is more or less favorable than the past (paleoclimate) periods or the projected future (late 21st century). The project will determine whether other flight corridors may have been more advantageous in the past or future than during the present period.Activity 2. Assessment of optimization...
