1984, Journal of Applied Ecology (21) 83-95
(1) Breeding red-winged blackbirds were used as a model to study the effects of a single application of an organophosphate insecticide, fenthion, on reproduction of altricial songbirds.(2) The insecticide had no significant effect on frequency of nest abandonment, clutch size, hatching success, or fledgling success.(3) Growth rates of young nestlings...
The use of a robust capture-recapture design in small mammal population studies: A field example with Microtus pennsylvanicus
James D. Nichols, Kenneth H. Pollock, James E. Hines
1984, Acta Theriologica (29) 357-365
The robust design of Pollock (1982) was used to estimate parameters of a Maryland M. pennsylvanicus population. Closed model tests provided strong evidence of heterogeneity of capture probability, and model M eta (Otis et al., 1978) was selected as the most appropriate model for estimating population size. The Jolly-Seber model...

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...

C. W. Poag
1984, Palaeogeography, Palaeoclimatology, Palaeoecology (48) 25-37
Bathyal and abyssal foraminifera in the Gulf of Mexico are distributed among thirteen generic predominance facies. Five predominance facies nearly encircle the Gulf basin along the slope and rise; a sixth predominance facies blankets the Sigsbee Plain, and a seventh is restricted to the Mississippi Fan. The remaining eight predominance...
Unzipping of the volcano arc, Japan
R. J. Stern, N. C. Smoot, M. Rubin
1984, Tectonophysics (102) 153-174
A working hypothesis for the recent evolution of the southern Volcano Arc, Japan, is presented which calls upon a northward-progressing sundering of the arc in response to a northward-propagating back-arc basin extensional regime. This model appears to explain several localized and recent changes in the tectonic and magrnatic evolution...
