Study: Alberta wolf cull stabilizes caribou numbers, but only buying time | CTV News EDMONTON -- New research shows that killing hundreds of wolves has barely managed to stabilize the numbers of a threatened Alberta caribou herd in a region increasingly impacted by industry. The study, conducted by some of the province's top caribou scientists and published online late last week, suggests that Albertans face a stark choice as their government prepares legally required plans to restore the herds. "One hopes that it's not just some window dressing that's going on," said Stan Boutin, a University of Alberta biologist and one of the co-authors. "If ... the plan is one that tries to satisfy all the players in the game, it becomes a thing where each of the players at the table are in there primarily to ensure they don't lose too much, as opposed to the overall objective. In an attempt to keep caribou from disappearing, Alberta began an annual cull of about 45 per cent of the wolves on that range in 2005. The study compares caribou numbers before and after the cull.

CO2 : la menace des zones mortes en expansion > Environnement Les océanologues s'inquiètent depuis plusieurs décennies de l'expansion des zones mortes, ces immenses nappes d'eau dépourvues d'oxygène où les espèces supérieures ne peuvent pas survivre. Les principaux responsables de ces désastres écologiques sont les engrais agricoles drainés aux embouchures des fleuves. Ainsi, toutes les formes de vie supérieure ont disparu en quelques dizaines d'années autour du delta du Mississipi et dans plus d'un quart de la mer Baltique. Les bactéries qui occupaient ces espaces avant l'apparition de la première forme de vie terrestre ont repris le contrôle de ces mers, annihilant plusieurs milliards d'années d'évolution. Une équipe de chercheurs danois vient de dresser un constat encore plus alarmant de la situation, en interprétant une dramatique expansion de ces zones comme un effet secondaire du réchauffement qui touche notre planète.

Dr. Thomas Griggs, Assistant Professor of Forage and Grassland Agronomy, West Virginia University, Morgantown was session moderator. Dr. Problem parasites in livestock, such as Haemonchus contortus, Haemonchus placei, Ostertagia ostertagi, Cooperia spp., Trichostrongylus spp., and Oesophagostomum species, caused a need for cattle, sheep, and goats to be treated with parasiticides. Once on the pasture surface, they hatch and crawl onto grass leaves. Three classes of drugs are approved for use in cattle: 1.) Include: Cydectin, Eprinex, Dectomax, Ivomec 2.)

Yellowstone wolf pack encircles two photographers . . . . ."wild and beautiful" Paradise Valley wildlife photographer Alan Sachanowski has written a very interesting and timely story about a recent experience he and another photographer had in Hayden Valley close up with the Gibbon wolf pack . . . Ralph Maughan ————————– By Alan Sachanowski.I have read with interest stories recently about individuals who have felt threatened by wolves in the back country. Forest Service employees being evacuated from a wilderness area because of a perceived threat, an armed bow hunter claiming to have been trapped in his tent for hours, and of course the hunter who inadvertently shot his guide a couple years ago in Paradise Valley Montana, because he mistook him for wolves that were “coming to get him”. The list of stories goes on. I thought that, perhaps, your readers might be interested in reading another “close encounter” type story. Copyright Alan Sacharnowski
Evolver Zone Le développement des zones mortes (privées d’oxygène) dans le milie... Colony Collapse Disorder: A Descriptive Study Report finds flaws in red wolf restoration effort RALEIGH, N.C. An independent review released Thursday found flaws in a 27-year program to restore the endangered red wolf, including the size of the habitat, inadequate understanding of population trends and poor coordination with local program managers. The review by the nonprofit Wildlife Management Institute was commissioned by federal wildlife officials as they consider whether to continue maintaining the world's only wild red wolf population in eastern North Carolina. A decision on how to proceed is expected in early 2015, and officials are also considering nearly 48,000 comments submitted during a period for the public to weigh in. Once common in the Southeast, the red wolf had been considered extinct in the wild as of 1980 due to factors including hunting and loss of habitat. The new 171-page report said the U.S. "There is no theoretical or practical reason to believe that red wolves will constrain their activities or movements to a jurisdictional boundary," the report said.
Abstract search | Walcott 2009 Zone morte aquatique dans les rivières et les océans Une zone morte est une zone aquatique avec une très faible teneur en oxygène dissous (hypoxie), qui provoque l'asphyxie de la faune et de la flore, et donc la mort de toute la biodiversité marine présente dans cette zone. Elles peuvent être présentes dans les mers et les océans, mais aussi dans les estuaires, les rivières, les lacs, les mares... La zone morte est la dernière phase de l'eutrophisation de l'eau, provoquée par le rejet de substances nutritives trop riches, provenant notamment des phosphates contenus dans les lessives, ainsi que l'azote et les nitrates, contenus dans les engrais utilisés dans l'agriculture intensive. La pollution de l'eau est provoquée également par les nombreux rejets industriels. L'étendue des zones mortes ne cesse de s'accroître : en 2008, environ 245 000 km² sont concernés. Plus de 400 zones mortes sont recensées sur la planète, la plus grande étant située dans la mer Baltique. Réduire l'hypoxie d'un littoral est un processus long et complexe.
WODCW FAQ Sheet on Wolf Hound Hunting | Wolves of Douglas County Wisconsin By Wolves of Douglas County Wisconsin (WODCW) A Grassroots Organization started to remove the dogs from the wolf hunt. 1. Out of all the states that hunt wolves, only Wisconsin allows hound hunters to use unleashed packs of dogs to hunt wolves. Wisconsin, quite literally, throws “dogs to the wolves.” 2. Hound hunters traditionally train their dogs to focus on specific prey by releasing their dogs to surround, attack and terrorize a prey animal (e.g. a bear cub or fox) for hours on end (up to 16 hours/day) enclosed in a small, open barrel or “roll cage.” 3. 4. 5. *These may not be reproduced or edited without permission from wolves of Douglas County Wisconsin.
