Armstrong collaborated with corresponding author Will Deacy and scientists from the University of Montana, Washington State University and the Kodiak National Wildlife Refuge to collar 33 female bears and track them for a year over a 1-million-square-kilometer portion of Kodiak Island. At the end of those 12 months, the team recaptured 18 of the bears and took hair samples that they measured for mercury. Salmon absorb mercury from what they eat in the ocean, and the amount of mercury in a bear’s hair By Steve Lundeberg Correspondent By Christine Coffin Correspondent BEND – A year after it expanded for public use, the Zagster bike share program launched by Oregon State University-Cascades will expand again, adding two new bike stations in Bend. The additional stations are located in Bend’s downtown area. With the station additions the bike share system has grown to 55 bikes and eight stations. A celebration to officially open the new stations took place at noon on July 30 at one of the stations located on NW Galveston Avenue, between 12th Street and Federal Avenue. The newest stations were made possible with sponsor- ship from 10 Barrel Brewing Company and SELCO Community Credit Union. The second station is located at the north end of downtown Bend on the south- west corner of the Newport Avenue and Wall Street intersection. 10 Barrel and SELCO join partners G5, Visit Bend, and the Old Mill District in supporting the bike share program. The program launched for the OSU-Cascades cam- pus community in the fall of 2016 with 30 bikes at three stations on and near the cam- pus. The addition of private sponsors in June 2017 made expansion to the public pos- sible and since then the pro- gram has gained more than 1,800 active members and recorded 4,900 user trips. Year-to-date, rides have more than doubled com- pared to the same period in 2017. With additional sponsors, university officials hope to expand the bike share program to the east side of Bend. Members of the pub- lic age 18 or older can join the program via the Zagster app or at www.zagster.com/ bend. A new pay-as-you-go option offers 30-minute trips – a typical trip length – for $1.50. CORVALLIS – Research shows that Kodiak brown bears that sync their stream- to-stream movements to salmon spawning patterns eat longer and more than bears that don’t, with one bear in the study consuming more than two tons of fish in one summer. Individual sockeye salmon populations spawn for about 40 days, but “resource surfing” bears can fish for three times that long, biologists have learned. Worldwide, prolonged salmon availability is increasingly under threat from hatchery supplemen- tation that tends to reduce the genetic diversity under- pinning different spawning times. In addition, bears’ ability to follow salmon waves is hampered by indus- trial development such as mining. indicates how much fish it dined on – the more mercury, the more salmon it ate. “Salmon consumption ranged from around 300 kilograms for one bear up to almost 2,000 kilograms for the biggest salmon eater,” said Deacy, a postdoctoral scholar at OSU. “This study complements our other research to show how bears depend on diverse salmon populations.” On average, the bears in the study ate more than 1,000 kilograms of salmon apiece, and the more fishing sites a bear visited, the more time it spent fishing. Salmon originating from different streams return from sea to spawn at different times, making resource surfing possible. “Results suggest that in intact watersheds with abundant salmon runs, year- to-year variation in salmon CUSTOM HOMES • RESIDENTIAL BUILDING PROJECTS John P.

Collaborators included Jack Stanford of Montana, Charles Robbins and Joy Erlenbach of Washington State, and William Leacock of the Kodiak refuge, who did the bear collaring and tracking. 541-549-9764 CCB# 159020 CCB# 16891 Becke W.
