eaglepedia revisited


October 27, 2007

Taking a look at the food chain - Part II Into The Wild - Biologists are just learning how far reaching the nutrients from the adult salmon can be. The inland ecosystem, far away from the river will be touched thru the Black and Grizzly Bears who capture the dying salmon, drag their bodies ashore away from the stream, feed on only part of the carcass, leaving the rest to be eaten by others including birds, mammals and insects. The urine and feces of the bears then carries the salmon biomass further into the woods, far away from the area where the salmon spawned and died. Birds and bats will also feed upon the insects that enjoyed their share of the salmon remains, which in turn further spread this bounty.

From Sea to Stream - A naturally occurring isotope of nitrogen, found in marine algae, help scientists evaluate the distribution of the salmon nutrients as it passes thru the food chain. This isotope occurs in marine algae and is further concentrated in the animals that feed upon it. Some of these plankton eating organisms then become a meal for the salmon while they are at sea and upon returning to the freshwater to spawn, they are carrying this stable isotope with them in their body tissue. Biologists have learned to read the "signature" of this compound and have been finding this nutrient of oceanic origin in places far from the sea.

As young salmon work their way downstream, they seek out cool, shaded pools. Alders, maples, and spruce trees growing along the stream banks spread their branches over the water, providing this shade. Studies have detected, within the tissues of the trees' leaves and needles, molecules of nitrogen bearing the telltale signature of the open ocean, delivered upriver by salmon and now helping to provide cool shelter for the next generation.

Hello, everybody.

Topa, safe journey, hope you get to see K-10 and/or K-26. Will be looking forward to seeing your photos. Have fun on your adventure.

Polar bear cam down, bummer. :unsure:

Deb, those are super eagle photos in your eaglepedia post. :)^

Flooring guy is here and is taking off the baseboards. Let the chaos begin...... my stomach is in knots but I think he will be careful. He's always been given positive comments from previous customers. House looks weird, all the appliances are in the front hall. Brynn is freaked out.

Topa - Have a splendid day and hope you get to see our special eagle couple.

Cheryl - Great article on the Monarch migration, they are so beautiful. Earlier this morning I was watching the whoopers all integrated into one group in front of the pen. It took 4 OM people to monitor them. One of the adults tried to peck at a juvie but was quickly given the
no-no by the OM helper. It's really interesting to see them all together.
