Determination of 2-isovaleryl-1,3-indandione with 2,4-dinitrophenylhydrazine. Rodenticide Analysis.
C. M. Menzie, V. A. Adomaitis, W. L. Reichel
1962, Analytical Chemistry (34) 516-518
At present, three 2-alkyl-1,3-indandiones (PMP, pival, and diphacinon) are widely used as rodenticides. Because analytical procedures now in use are empirical and do not furnish adequate or positive means for distinguishing among these closely related compounds, studies were undertaken to develop a sensitive and specific method for the determination...
Evaluating causes of population change in North American insectivorous songbirds
C.S. Robbins
1962, Audubon Field Notes (16) 142
Although the North American Breeding Bird Survey (BBS) is a principal source of information regarding populations of most North American bird species, many features of the survey complicate analysis of population change.

Portrayal of drainage and vegetation on topographic maps
W.J. Schneider, J. C. Goodlett
1962, Open-File Report 62-121
Accurate measurements of drainage networks are necessary for studies in many scientific disciplines, especially hydrology. To this end, topographic maps must show accurate classification as well as a consistent pattern of the stream network.A recent study in Georgia has developed two photo-interpretive keys which permit accurate drainage classification during the...
