Satellite telemetry options for avian research
D. H. Ellis, M.R. Fuller
1993, Journal of Raptor Research (27) 87 (abs)
Four manufacturers now produce transmitters in the size range suitable for raptors (3-5% of body mass). Dummies of these transmitters will be displayed and harnessing techniques will be demonstrated. Estimates will be given for: cost, reliability, longevity, mass, availability, programmability, power output and other information essential in deciding on manufacturer...

Use of satellite telemetry for study of a gyrfalcon in Greenland
S.S. Klugman, M.R. Fuller, P.W. Howey, M.A. Yates, J.J. Oar, J.M. Seegar, W.S. Seegar, G.M. Mattox, T.L. Maechtle
1993, Journal of Raptor Research (27) 75-76(abs)
Long-term research in Greenland has yielded 1 8 years of incidental sightings and 2 years of surveys and observations of gyrfalcons(Falco rusticolus) around Sondrestromfjord, Greenland. Gyrfalcons nest on cliffs along fjords and near rivers and lakes throughout our 2590 sq. km study area. Nestlings are present mid-June to...
Type specimens and basic principles of avian taxonomy
Richard C. Banks, Steven M. Goodman, Scott M. Lanyon, Thomas S. Schulenberg
1993, The Auk (110) 413-414
"Ornithology" may be defined as the scientific study of birds. No aspect of avian biology, including management and conservation, can be carried out without reference by name to birds at some taxonomic level. Thus, the names of species of birds, and of groups of species, can fairly be considered...
Nests and eggs of colonial birds nesting in Malheur Lake, Oregon, with notes on DDE
J.E. Cornely, S.P. Thompson, Charles J. Henny, C.D. Littlefield
1993, Northwestern Naturalist (74) 41-48
We describe the nests and eggs of 7 species of colonial birds that nested on Malheur Lake in Malheur National Wildlife Refuge, Oregon, in 1980 and 1981. All nests were constructed over water in stands of hardstem bulrush (Scirpus acutus). We compared nest measurements among species and found...
Capture-recapture studies for multiple strata including non-markovian transitions
C. Brownie, J.E. Hines, J.D. Nichols, K. H. Pollock, J.B. Hestbeck
1993, Biometrics (49) 1173-1187
We consider capture-recapture studies where release and recapture data are available from each of a number of strata on every capture occasion. Strata may, for example, be geographic locations or physiological states. Movement of animals among strata occurs with unknown probabilities, and estimation of these unknown transition probabilities...

Effects of acidification on metal accumulation by aquatic plants and invertebrates. 2. Wetlands, ponds and small lakes
P.H. Albers, M.B. Camardese
1993, Environmental Toxicology and Chemistry (12) 969-976
Compared were concentrations of Al, Cd, Ca, Cu, Fe, Pb, Mg, Mn, Hg, Ni, P, and Zn in water, plants, and aquatic invertebrates of wetlands, ponds, and small lakes in Maryland and Maine. The accumulation of metals by aquatic plants and insects and the concentration of metals in water were...

Down-regulation of muscarinic receptors and the m3 subtype in white-footed mice by dietary exposure to parathion
David A. Jett, E. F. Hill, J.C. Fernando, M.E. Eldefrawi, A.T. Eldefrawi
1993, Journal of Toxicology and Environmental Health (39) 395-415
The effect of ad libitum dietary exposure (as occurs in the field) to parathion for 14 d was investigated on the muscarinic acetylcholine receptor (mAChR) in brains and submaxillary glands of adults of a field species, the white-footed mouse Peromyscus leucopus. Immunoprecipitation using subtype selective antibodies revealed that the relative...
Turbidite systems: State of the art and future directions
W. R. Normark, H. Posamentier, E. Mutti
1993, Reviews of Geophysics (31) 91-116
The study of turbidite systems covering a wide range of physical scales has led to confus ion regarding the use of certain key terms and hence a breakdown in communication between workers involved in turbidite research. There are three fundamentally different scales and types of observations derived from the study...
Two major Cenozoic episodes of phosphogenesis recorded in equatorial Pacific seamount deposits
J.R. Hein, Yeh Hsueh-Wen, S.H. Gunn, W.V. Sliter, L.M. Benninger, Wang Chung-Ho
1993, Paleoceanography and Paleoclimatology (8) 293-311
Seamount phosphorites have been recognized since the 1950s, but this is the first study to provide an in depth exploration of the origin and history of these widespread deposits. Representative samples from equatorial Pacific Cretaceous seamounts were analyzed for chemical, mineralogical, and stable isotope compositions. The phosphorites occur in a...
Spring climate and salinity in the San Francisco Bay Estuary
Daniel R. Cayan, David H. Peterson
1993, Water Resources Research (29) 293-303
Salinity in the San Francisco Bay Estuary almost always experiences its yearly maximum during late summer, but climate variability produces marked interannual variations. The atmospheric circulation pattern impacts the estuary primarily through variations of runoff from rainfall and snowmelt from the Sierra Nevada and, secondarily, through variations in the near-surface...

1993, Research Paper SO-274
The purpose of the research was to evaluate the efficacy of point count surveys in bottomland hardwood forests. The specific objectives were to determine: (1) whether the recommended distance measures for point count circular plots are useful in bottomland hardwood forests, (2) the optimum duration for each point count, (3)...

1993, Biological Report No. 18
Data from several sources were collated and analyzed by correlation, regression, and principal components analysis to define surrrogate variables for use in the brook trout (Salvelinus fontinalis) habitat suitability index (HSI) model, and to evaluate the applicability of the model for assessing habitat in high elevation streams of the southern...

Acidic Depositions: Effects on Wildlife and Habitats
1993, Wildlife Society Technical Review 93-1.
The phenomenon of 'acid rain' is not new; it was recognized in the mid-1800s in industrialized Europe. In the 1960s a synthesis of information about acidification began in Europe, along with predictions of ecological effects. In the U.S. studies of acidification began in the 1920s. By the late 1970s research...
