Wolves Reproducing around Oregon
Jul. 30th, 2013 12:53 pmThis is great news in my book. I was out at the Imnaha river in spring and there is one of the first packs reported to have pups. I saw no sign of them. Now it sounds like most of the known Oregon packs have pups this year, even the newly discovered pack. Wild carnivores on the rise! We now have 53 wolves in Oregon. The ranchers hate it of course, but hopefully we can reach some equilibrium between livestock and canines that everyone can tolerate. I wonder if there might be some way to keep wild canines at bay that is as elegant as moving lights to keep away lions. Of course it's hard to protect your bovines when they're wandering far and wide...like those cows all along the Yampa. Need a wolf network up there too, keep the ranchers in line.

Because mercury bio-accumulates, and otters are SO carnivorous, they are like the canary in a coalmine for the detection of mercury. The Wisconsin Dept of Natural Resources asked all the otter trappers for the carcasses and tested various tissues for mercury levels. The levels were highest in fur, with descending concentrations in these tissues: liver, kidney, muscle, and brain. Methyl-mercury made up a greater percentage of total Hg in brain and muscle compared to liver and kidney tissue. So far none of the otters appears to be sickened by their mercury load. The levels in the fur are directly related to the levels in internal tracking, so I suspect future research may follow living otters to see what they're taking in. "A gradient" in tissue concentrations was noted from north to south, but they don't say which way the gradient goes. Perhaps more to the south, like in fish? We shall see.

Also, at http://www.glc.org/glad/projects/basu09/ they are monitoring eagles and otters for biomarkers. The specific aims of this proposal are: 1) Exposure Assessment : to determine tissue mercury and PBDE levels in river otters and bald eagles from several Great Lakes states, with a focus on animals collected from existing statewide monitoring programs in Michigan and Wisconsin; 2) Health Assessment : to determine river otter and bald eagle health status by means of neurochemical biomarker studies on key receptors (muscarinic, glutamate) and enzymes (monoamine oxidase, cholinesterase) in physiologically important brain regions; 3) Risk Characterization : to determine if there is a statistical association between mercury and PBDE exposure (Aim #1) and alterations in neurochemical biomarkers (Aim #2); and 4) Education and Capacity Building : to build capacity among academic researchers and government/state managers and to disseminate results to scientific and regulatory communities.

Otters Having Lunch on the Washougal River
Jan. 4th, 2010 06:41 pmThis is the same piece of music as he used for the previous post, so if you hate the music, don't play it. Dick filmed this otter family fishing and eating their catch on the rocks behind his house. It's stuff like this that confirms for me that I want to live on the crick. Somewhere. Some gurgle or cascade, or even better, small clean river. But back to otters. I might get a chance to study otters this coming summer, and I was already interested. RIVER otters, not ocean, they are different. Know anything about them?

Dream: The Tiger
Sep. 27th, 2007 03:12 pmThere is a tiger in the basement. She is a young tiger. I'm staying at someone else's house, and I ask the residents whose tiger she is. They say that she is nobody's tiger, she was left behind. She's 90-100 pounds, I'd guess, agile and athletic. I don't want to tackle her, but she isn't interested in me. She is long and lean and beautiful.

The Cat Chronicles
May. 7th, 2007 02:37 pmShakti the ferocious feline is sprawled on one of my two desks, watching me sort through my papers. She is long haired with a white chest and belly, and black and gray mottling over her back and sides, with a huge coon tail. She is satisfied as long as she is in the middle of everything. I have had to knock her off the desk a couple of times when she went to play with the orange flowers in the vase. She usually manages to upend my flowers, but I am learning to use vases that won't tip over. The current floral arrangement is particularly gorgeous, lean, long and assymmetrical, arising from an amber vase with a round bulb of a base. Flowers bring me joy, as does the kitten, when she is not in the process of killing something.

Yesterday my friends Leland and Andria (and their wolf dog) passed through Flagstaff. We go back, in fact I knew both of them before they met each other. This time they are headed to the Left Coast to paddle for the summer. Their paddling tour begins at the Kern river, and then goes north as the summer progresses. I think they plan to head home from Canada in August. They should be kayaking tomorrow. It's all a business expense, all this travelling and kayaking. They write guidebooks about rivers, and make yoga videos for climbers/paddlers/hikers/bicyclists, and sell them at http://www.brushymountainpublishing.com.

This morning Shakti on Four Paws caught another grey bird, which went in the trash. Then I went on a hike and was gone for about 3 hours. When I got home she had a dead red-headed bird, and fresh grey bird, still fighting. She would pin it to the carpet, and then let go the same way she does a toy. Released, the bird would take flight for the window. The window was only open a crack, and because the feathered creature possessed only a birdbrain, it would fly into the glass every time. Shakti the huntress would jump up and nail it against the glass, and take it in her teeth back to the carpet. I witnessed two cycles of this vicious game before I figured out the solution. I opened the window all the way, and the next time the kitten let the bird go, it flew out the window and left her stunned.
Moments later I had recovered her collar with the bell from my side table drawer. I had to let the collar out a couple of inches from the last time that I had it on her. She hates it. Now she is trying to get it off. She will, too. I am sure that I will have to find a more secure collar for this kitten. She is born to hunt in silence.
I do not mind her huntress nature, but I do not enjoy the scene of carnage in my room. She must have tormented the red-headed bird for a long time, because its blood was smeared on my kitchen floor, and there were feathers EVERYWHERE. I have vacuumed twice today already. Shakti is pissed. She will get madder, and she will never accept wearing a bell. Is there a better solution?
