Perspective rendering showing retreat of the Skilak Glacier, a major source of glacial runoff to the Kenai River. Colored lines indicate ice extent for 1952, 1978, and 2013 derived from aerial photographs. The toe of Skilak Glacier retreated only slightly between 1952 and 1978 and then it retreat...

Concentration of (A) fishery permits and (B) variability in fishery revenues for selected communities of the Kenai Peninsula Borough (source: Alaska Commercial Fisheries Entry Commission). Fisheries concentration is quantified using Simpson’s diversity index, with higher values indicating more co...

Returns (total run size: escapement + harvest) of adult Chinook and Sockeye salmon to the Kenai River and a major tributary, the Russian River (ADFG data). Returns are plotted separately for populations or “runs” of each species that differ in spawning habitat and timing. The early runs of each s...

Commercial fishing revenues earned by residents of the Kenai Peninsula Borough, by type of fishery (source: Alaska Commercial Fisheries Entry Commission). “Salmon: UCI” refers to the Upper Cook Inlet drift and set gillnet salmon fisheries; “Salmon: Other” refers to all other salmon fisheries in t...

Trends in harvest and effort in the commercial gill net (A), recreational hook-and-line (B), and personal use dip net and gill net (C) fisheries on the northern Kenai Peninsula. Commercial fisheries harvest more salmon than the other fisheries combined (note different y-axis scales), but the spor...

The expanding footprint of human development in the lower Kenai River watershed based on analysis of aerial photographs. Inset in top panel shows location within entire Kenai River watershed (dark outline). Most development is concentrated in the lowlands near the river mainstem and tributaries...

Salmon face risks from a rapidly changing climate, landscape change, and ocean acidification, but may also benefit from warming temperatures and glacial retreat under some circumstances. Management decisions will influence whether Alaskan salmon ecosystems and fishing communities continue to thr...

The download includes CAD drawing for building an augmented reality sandbox and a link to a forum that will help with installation of the software. EPSCoR personnel have created educational curricula for use in conjunction with the sandbox, aimed at students in grades 6-12. The curriculum module...

There is growing concern that a warming climate will alter water supplies in many regions. Determining the best course of management and adaptation is an important task for water managers. This study explores the impact of climate warming and differing treeplanting scenarios on water supplies (pe...

Climatic change is anticipated to alter disturbance regimes for many ecosystems. Among the most important effects are changes in the frequency, size, and intensity of wildfires. Serotiny (long-term canopy storage and the heat-induced release of seeds) is a fire-resilience mechanism found in many ...

Estuaries and nearshore marine systems are foundational habitats for the ecological, cultural, and economic vitality of southeast Alaska. These nutrient rich systems provide forage for a multitude of fish and wildlife species – and as a result, economic opportunities for coastal communities — suc...

The sustainability of salmon within this ever-changing climate is a question posed by many whose lives focus on this natural resource and its future. South Central Alaska is no exception to this, and as such the Salmon 2050 Project through EPSCOR places focus upon the South Central area to addres...

Nuiqsut is a native village located on the Colville River; its residents travel great distances on the river—from Umiat to the Ocean—for subsistence. Recently, residents have noticed accelerated changes in the river environment. Residents report bank erosion both in the village and throughout the...
