first_imgBryum argenteum, B. pseudotriquetrum and Ceratodon purpureus are the predominant mosses in Victoria Land, continental Antarctica. All have cosmopolitan distributions and are widespread throughout Antarctica with wide ecological amplitudes resulting in considerable morphological variation. They are well adapted to tolerate the physiological stresses imposed by the severe environment. This study investigates aspects of their growth, physiology and survival in response to habitat constraints, especially hydrology. Their distribution is controlled almost exclusively by moisture availability. Each species tends to predominate in a specific zone along hydrological gradients, with B. pseudotriquetrum on moist soil, C. purpureus on drier soil, and B. argenteum on unstable stream margins, fluvial deposits and the marginal capillary zone. Where conditions are optimal, each species can form a turf 6–10 cm thick. Nutrient status of the soil does not appear to be an important determinant in the distribution pattern within communities. The thermal regime of the moss turf varies according to its moisture content; for a period of ca. six weeks during the summer, with the frequent long spells of 24-h sunshine, temperatures remain above 0 °C for much of the time even though air temperatures are frequently below the freezing point. This allows growth and metabolic activity to proceed continuously at a relatively rapid rate for quite long periods. Annual shoot incremental growth can exceed 3.5 mm in each species. Growth of B. argenteum may be inhibited by UV- B radiation. The optimal temperature for photosynthesis in each species is around 15 °C, but significant carbon fixation occurs at 5 °C. Photosynthetic rates at 5, 10 and 20 °C were B. argenteum > B. pseudotriquetrum > C. purpureus.last_img read more

first_img“The key to success has always been timely management,” Hancock said. Good management has become more efficient through the use of improved forage varieties, advanced harvest equipment and other technologies that have come to the market during the last decade, he said. “It is hard to recall a more exciting time in the hay and forage industry,” he said. To celebrate, Hancock and other hay contest organizers decided to up the ante on their hay contest with the help of some big-name sponsors, especially new title sponsor, Massey Ferguson. The company will provide the use of a new Massey Ferguson RK Series rotary rake for the 2016 hay production season and $1,000 cash as the grand prize for this year’s contest. Cash prizes will be provided to first, second and third place winners in each of the seven categories.Massey Ferguson will also provide the winner of first place in the warm season perennial grass category with the use of a new DM Series professional disc mower for the 2016 hay production season. Additional industry partners sponsored each of the seven categories. These sponsorships will provide cash awards to the top three places in each category, including $125 for first prize, $75 for second prize and $50 for third prize. Georgia Twine is sponsoring the warm season perennial grass category. America’s Alfalfa is sponsoring the alfalfa hay category. Silo-King is sponsoring the perennial peanut hay category. Inland Tarp & Liner is sponsoring the cool season perennial grass category. Athens Seed Company is sponsoring the mixed, annual grass and other hay category, and Tube-Line is sponsoring the grass baleage and legume baleage categories. Hancock encourages producers from all 13 Southeastern states to check out the rules and entry forms and to enter today. The deadline for entry into the Southeastern Hay Contest is 5 p.m. on Monday, Sept. 28. Winners will be recognized at the Sunbelt Ag Expo, in Moultrie, Georgia, in October. More information about the contest, including the rules and entry form, is available at bit.ly/SEHayContest2015. Also, follow the Southeastern Hay Contest on Twitter (@SEHayContest) and Facebook at www.facebook.com/SEHayContest for periodic articles, updates and timely information on producing high quality hay and baleage. Hay doesn’t always get the respect it deserves. You won’t find it featured in any “farm-to-table” magazine spreads or highlighted in a “Got hay?” marketing campaign. Good hay’s not flashy, but without it, great steaks and cheese would be impossible. This year’s baleage and hay producers from across the Southeast have a chance to show off the fruits of their labor at the Southeastern Hay Contest at the Sunbelt Ag Expo in October. The registration deadline is Monday, Sept. 28. This year’s contest features cash prizes for the winners of all seven categories, as well as free use of Massey Ferguson-brand hay equipment for the production season. For more than a decade, the Southeastern Hay Contest has been spotlighting high-quality hay and baleage production in the region. The Cooperative Extension programs in Alabama, Florida, Georgia and South Carolina have organized the contest since its inception. “We hope every high-quality hay producer from Texas to Virginia will enter for a chance to win,” said Dennis Hancock, University of Georgia Cooperative Extension forage specialist and director of this year’s contest. “Our goal is to demonstrate the potential to produce high-quality hay and baleage in the Southeast. Just as important, we want to highlight the technology that makes it all possible.” This year’s entries will be judged on their composition, including protein and total digestible nutrients (TDN), and on relative feed quality scores. Because of higher livestock prices, forage producers are seeing an increased demand for their baleage and hay. With increased demand, prices for hay and baleage have gone up, and livestock producers are demanding better quality hay and baleage for those higher prices. As a result, the quality of forage crops has increased dramatically over the last decade, Hancock said. last_img read more

first_imgDanielle Rochette APTN NewsAt the time, Alexis Joveneau was highly regarded in the Innu community of Pakuashipi and La Romaine (Unamen Shipu). The missionary from Belgium had such an effect on the Innu that for years they kept their silence about what he was doing.Joveneau didn’t just have a hold on the Innu – Canada and the province of Quebec threatened to pull all subsidies from the community if they didn’t follow his plan. But as it turned out, Joveneau was a sexual predator.Simone Bellefleur was nine years old when she was abused for the first time by Joveneau. “Now I notice things what this priest put us through I always felt anger,” said Simone Bellefleur who was nine years old when she was first abused by Joveneau. He harassed and molested many young Innu girls and women during his years along the northern shores of the St. Lawrence river – with impunity. Joveneau first arrived in Unamen Shipu in 1953.The missionary (Oblate) learned the Innu language and translated religious courses and the mass in Innu.He stayed 39 years and died in 1992.(Alexis Joveneau in an undated photo)He is buried in Unamen Shipu. The government gave him control of the welfare cheques to distribute to the Innu.Hi plan was to move the Innu of Pakuashipi to Unamen Shipu, 300 km west along the St. Lawrence River.“I was carrying this anger within me,” Bellefleur told the commissioners. “What frustrated me and angers me today I am a mother I always want to be violent against my daughter.”Catholicism is still being practiced by many Innu communities today. But Bellefleur said she decided to take another path after attending a Sundance Ceremony a decade ago. “That is where I saw the faith of my ancestors my grandparents, grandfathers, grandmothers,” she said. “And now I live my life with these aboriginal beliefs they are part of my life and it has been some ten years that I am following a spiritual path.”As part of her healing, she also made recommendations to the inquiry. “I made my recommendation for us to receive a camp with a therapy centre because everyone needs it,” she said.last_img read more
