Tissue lead distribution and hematologic effects in American kestrels (Falco sparverius) fed biologically incorporated lead
T. W. Custer, J. C. Franson, O. H. Pattee
1984, Journal of Wildlife Diseases (20) 39-43
American kestrels were fed a diet containing 0.5, 120, 212, and 448 ppm (dry wt) biologically incorporated lead (Pb) for 60 days. The diet consisted of homogenized 4-wk-old cockerels raised on feed mixed with and without lead. No kestrels died and weights did not differ among treatment groups. The control...

1984, Colonial Waterbirds (7) 74-79
Feeding flights of Snowy Egrets (Egretta thula), Tricolored Herons (E. tricolor), Little Blue Herons (E. caerulea), and Cattle Egrets (Bubulcus ibis) were monitored at a small nesting colony near Chincoteague, Virginia during late May and June 1979. All four species varied their flight directions over a series of days....
DDE in birds' eggs: Comparisons of two methods for estimating critical levels
L. J. Blus
1984, The Wilson Bulletin (96) 268-276
The sample egg technique and eggshell thickness-residue regression analysis were comparatively evaluated as tools in estimating critical levels of DDE in birds? eggs that seriously affect reproductive successa nd population starts....In comparing critical values of DDE that were derived from the two methods, the estimates were lower using the sample...
Testing for variation in taxonomic extinction probabilities: A suggested methodology and some results
M.J. Conroy, J.D. Nichols
1984, Paleobiology (10) 328-337
Several important questions in evolutionary biology and paleobiology involve sources of variation in extinction rates. In all cases of which we are aware, extinction rates have been estimated from data in which the probability that an observation (e.g., a fossil taxon) will occur is related both to extinction rates and...
A general methodology for maximum likelihood inference from band-recovery data
M.J. Conroy, B. Kenneth Williams
1984, Biometrics (40) 739-748
A numerical procedure is described for obtaining maximum likelihood estimates and associated maximum likelihood inference from band- recovery data. The method is used to illustrate previously developed one-age-class band-recovery models, and is extended to new models, including the analysis with a covariate for survival rates and variable-time-period recovery models....
Organochlorine pesticide residues in moths from the Baltimore, MD-Washington, D.C. area
W. N. Beyer, T. E. Kaiser
1984, Environmental Monitoring and Assessment (4) 129-137
Moths were collected with a light trap from 15 sites in the Baltimore, Maryland-Washington, D.C. area and analyzed for organochlorine pesticide residues. On the average, the species sampled contained 0.33 ppm heptachlor-chlordane compounds, 0.25 ppm DDE, and 0.11 ppm dieldrin. There were large differences in the concentrations detected in different...
Simulation analyses of space use: Home range estimates, variability, and sample size
Marc Bekoff, L. David Mech
1984, Behavior Research Methods, Instruments, and Computers (16) 32-37
Simulations of space use by animals were run to determine the relationship among home range area estimates, variability, and sample size (number of locations). As sample size increased, home range size increased asymptotically, whereas variability decreased among mean home range area estimates generated by multiple simulations for the same sample...
Acute responses of American kestrels to methyl parathion and fenvalerate
Barnett A. Rattner, J. C. Franson
1984, Federation Proceedings (43)
Physiological and toxicological effects of p.o, methyl parathion (0.375-3.0 mg/kg) or fenvalerate (1000-4000 mg/kg) were examined over a 10 h period in American kestrels (Falco sparverius) maintained in thermoneutral (22?.C) and cold (-5?.C) environments. Methyl parathion was highly toxic (LD50=3.08 mg/kg, 95% confidence limits=2.29-4.l4 mg/kg, producing overt intoxication (abnormal posture,...

1984, Book chapter, Proceedings of the Workshop on Management of Nongame Species and Ecological Communities
Historically, management of forests for wildlife has emphasized creation of openings and provision for a maximum of edge habitats. Wildlife managers have believed, quite logically, that increased sunlight enhances productivity among plants and insects, resulting in greater use by game animals and other wildlife. Recent studies comparing breeding...
Ecological considerations for the use of dispersants in oil spill response

1984, Book chapter, Oil Spill Chemical Dispersants: Research, Experience, and Recommendations
A multidisciplinary task force with membership from government agencies, academia, and industry is developing ecologically based guidelines for dispersant use in marine and estuarine environments. The guidelines are organized by habitat type (e.g., coral reefs, rocky shores, bird habitats) and consider dispersant use to protect the habitats from impact, to...

Evaluation of the efficiency of streamflow data collection strategies for alluvial rivers
P.K. Kitanidis, O. G. Lara, R.W. Lane
1984, Journal of Hydrology (72) 85-103
Streamflow discharge is usually determined indirectly from measurements of the river stage at gaging stations and through the use of stage-discharge relationships (rating curves). However, in alluvial streams, stage-discharge relationships change continually and, sometimes, quite markedly. Such changes may be caused by major floods, seasonal variations, or long-term secular trends...

L. Marincovich Jr.
1984, Palaeogeography, Palaeoclimatology, Palaeoecology (46) 11-24
Neogene marine sediments of the West Coast of North America were deposited in a series of widely spaced basins that extended geographically from the western and northern Gulf of Alaska (60°N) to southern California (33°N). Rich molluscan faunas occur extensively throughout these deposits and form the basis for biostratigraphic schemes...
