first method, samples are collected and the concentration of DON or individual DON components are monitored over time. To measure DON flux rates using 15N tracer techniques. all of the DIN forms (N~ + , NO3 -.and NO2 -) must be removed, and the DON pool must be isolated with a high efficiency. At present. there are three basic approaches used to isolate DON-wet chemistry, ion retardation, and d...
متن کاملComparison of Coastal Fringe and Interior Forests as Reserves for Marbled Murrelets on Vancouver Island
Much of the protected habitat available to the threatened Marbled Murrelet Brachyramphus marmoratus and other old-growth associated species in the Pacific Northwest is in narrow strips along the coast (e.g., parks and scenic fringes). Using data over two years from three watersheds on southwest Vancouver Island, we show that such shoreline strip forests represent suboptimal habitat for murrelet...
متن کاملLong Island Clast Orientations
Long Island glacigenic surface deposits, where exposed, are ideal for geologic field studies of Pleistocene glacial settings. Numerous outcrop exposures, found scattered throughout the island, delineate many of the deposit types associated with a full spectrum of glacial facies currently observable at active continental ice sheet margins. By directly field sampling axial orientations of a numbe...

Let r, s, q,m, n ∈ N be such that s ≥ r ≤ q. Let Y be a fibered manifold with m-dimensional basis and n-dimensional fibers. All natural affinors on (J(Y,R)0) are classified. It is deduced that there is no natural generalized connection on (J(Y,R)0). Similar problems with (J(Y,R)0) instead of (J(Y,R)0) are solved.
