10A COTTAGE GROVE SENTINEL March 2, 2016 OSU study: Hatcheries cause substantial, rapid genetic changes BY DAVID STAUTH Oregon State University A new study on steelhead trout in Oregon offers genetic evidence that wild and hatchery fi sh are different at the DNA level, and that they can be- come different with surprising speed. The research, published today in Na- ture Communications, found that after one generation of hatchery culture, the offspring of wild fi sh and fi rst-genera- tion hatchery fi sh differed in the activity of more than 700 genes. A single generation of adaptation to the hatchery resulted in observable changes at the DNA level that were passed on to offspring, scientists re- ported. This research was conducted at Or- egon State University in collaboration with the Oregon Department of Fish- eries and Wildlife. Scientists say the fi ndings essentially close the case on whether or not wild and hatchery fi sh A new study shows genetic differences between hatchery- raised fi sh and wild steelhead like these. can be genetically different. Differences in survival and reproduc- tive success between hatchery and wild fi sh have long offered evidence of rapid adaptation to the hatchery environment. This new DNA evidence directly mea- sured the activity of all genes in the offspring of hatchery and wild fi sh. It conclusively demonstrates that the ge- netic differences between hatchery and wild fi sh are large in scale and fully heritable. “A fi sh hatchery is a very artifi cial en- vironment that causes strong natural se- lection pressures,” said Michael Blouin, a professor of integrative biology in the OSU College of Science. “A concrete box with 50,000 other fi sh all crowded together and fed pellet food is clearly a lot different than an open stream.” It’s not clear exactly what traits are being selected for, but the study was able to identify some genetic changes that may explain how the fi sh are re- sponding to the novel environment in the hatchery. “We observed that a large number of genes were involved in pathways re- lated to wound healing, immunity and metabolism, and this is consistent with the idea that the earliest stages of do- mestication may involve adapting to highly crowded conditions,” said Mark Christie, lead author of the study. Aside from crowding, which is Please see HATCHERY, Page 11A D ATES Continued from page 7A “expiration date” stamped on the carton is the last day a retailer can sell the eggs as fresh. Eggs are still consid- ered safe to consume up to fi ve weeks if they are held in refrigeration after purchase at 40 degrees or colder. ODA food safety inspec- tors do pay attention to certain dates on products offered for sale. Looking at the poten- tially hazardous ready-to-eat foods that are unpackaged or prepared in the store is a high priority and violations are considered critical. Retailers and suppliers are usually motivated to observe these dates and clear out the old stuff while bringing in the new. “It’s not 100 percent but, for the most part, grocery stores are keeping a close eye on those products,” says Hawkins. “Between the dis- tributor of the product and the store itself, they are in there rotating products.” For consumers, the bottom line is that food product dates are worth paying attention to but not necessarily for food safety reasons. Those dates can help ensure the food you buy retains its quality. Of course, a lot depends on how the food is handled after purchase and how quickly it is consumed. COMMUNITY BRIEFS LWV to meet The Cottage Grove League of Women Voters will be hosting a unit meeting Wednesday, March 9 at 2:30 p.m. at Lane Community College in Cottage Grove. The discussion this month will be focusing on “What’s Happening in Cottage Grove”, in- cluding the local food movement, economic development, healthy kids in a healthy community, homeless- ness and collaborative efforts to in- crease the livability of the community. The unit meetings are always open to guests. Caregiver Network meets The fi rst Monday of every month includes a care-giving meeting and potluck at the Cottage Grove Bible Church at Quincy Avenue and 12th St. in Cottage Grove, from 11 a.m. to 1 p.m. The group aims to serve the com- munity as a resource pool of home- care workers who are available, local and experienced and have state pro- vider numbers. It also offers services that don’t require an agency and can at times help care-givers learn about available job opportunities. Its next meeting will be on Monday, March 7 at 11 a.m. The guest speakers are from Cornerstone Services, Inc., a non-profi t corporation, which is a professional fi duciary company. The company manages persons and their estates by acting in a fi duciary role as Conservator, Guardian, Trustee or Power of Attorney. Attendees can feel free to bring a friend and/or their client. Those seek- ing more information can contact a network coordinator: Shirley Mc- Daniel at 541-232-0966 or Virginia R. at 541-942-3108. Traffi c study Southern Oregon University MBA students are working with the Or- egon Department of Transportation to study the incidence of distracted driv- ing in Oregon. The department’s aim is to help reduce crashes involving distracted driving. By volunteering to complete this anonymous survey, participants will be providing valu- able feedback!

Main St. FEAST is an Oregon Food Bank program in rural communities. This meeting is open to the public. HAIRSTYLES Five must-have styles as seen at fashion shows 1. MESSY HAIRSTYLES If you hate spending lots of time doing your hair, you’re going to love this style. The ultra-neat heads of last winter are gi ving way to long, unruly locks. We’ll be seeing lots of low-slung messy braids and strands that casually frame the face. The key word here is texture. Dry shampoos and texturizing pastes are going to be your best friends this spring. 2. THE PONYTAIL Seen virtually year-round in all its various forms, the ponytail is still hot this spring. Keep up with the latest trend by wearing it very low and crimping a few strands of hair here and there with a styling paste. 3. WHERE TO PART? This spring, no half measures: the part is either right down the middle of the head or low on the side. If you wear a middle part, tuck your hair behind the ears. The side part is drawn very close to the ear and can be incorporated into a messy style or a very smooth, low bun. 4. ROMANTIC WAVES The fashion parades have made it very clear: this spring, fl at irons are out. Waves and natural curls are to be in the spotlight when wearing your hair loose. If your hair often loses its body as the day goes on, concoct your own “beach effect” spray by mixing salt, water and coconut oil. 5. COLOUR 2.0 If you enjoy experimenting with colour, take notes. Pastel colours are gradually losing ground to more striking shades such as electric blue or forest green. A rather unusual trend: natural tones combined with brightly coloured roots for a cutting edge look. What’s more, wide gray streaks are making their appearance near the face. www.nushkasspa.com Are you going to be daring and “Organic Spa” show your true colours this year? Manicures & Pedicures, Body Wraps, Facials, Massage, “Natural Nails” (no smells or fumes) Organic Skin Care Products Five trends to try this spring 1. A CANDY PINK MOUTH A hot trend at many of this season’s fashion shows, pink is set to take over your lips. Choose a bubble gum shade for a deliciously fresh and colourful mouth. The most adventurous among us will dare to try an orangey pink for a totally energized look. 2. SMOKY EYES, ALWAYS AND FOREVER The smoky-eyes look always has a place in makeup trends, no matter what the season. This spring, refresh your smoky eyes with eye shadow and eyeliner in blue (THE trend), gold, copper or mauve. 3. EYEBROWS: GO FOR BROKE For the most part, we’re seeing eyebrows continue to do exact- ly as they please, so metimes arched and thick, sometimes lacquered and shiny. But for some fashion avant-gardists, eyebrows are taking on a futur- istic look with a bleached-out effect. 4. THE RETURN OF THE 1960S Several key elements of the 60s are in again these days. Think doll-like eyelashes, opaque eye shadow and the lower eye lids lined with kohl, as popula rized by the famous 60s model Twiggy. White also works well to brighten eyes. 1508 Willamette St, Eugene 541-343-3150 $11 Haircuts Acrylic & Gel Nails 5. A HEALTHY COMPLEXION After dominating catwalks for several seasons, the nude effect is giving way to a healthy glow. Lay your bets on pink blush applied to the cheekbones. The goal is to create a fresh, natural look. A fresh look is still popular for summer makeup.
