1992, Book chapter, Proceedings of the 1988 North American Crane Workshop
The U.S. Fish and Wildlife Service (Service) is responsible for recovery of endangered species in the wild and, when necessary, maintenance in captivity. These programs provide an immediate measure of insurance against extinction. A prerequisite inherent in all of these programs is the preservation of enough genetic diversity to maintain...
Karyotype and identification of sex in two endangered crane species

Don A. Wood, editor(s)
1992, Book chapter, Proceedings of the 1988 North American Crane Workshop
A laboratory procedure for sex identification of monomorphic birds was developed using modern cytological methods of detecting chromosome abnormalities in human amniotic fluid samples. A pin feather is taken from a pre-fledging bird for tissue culture and karyotype analysis. Through this method, the sex was identified and the karyotype described...

1992, Book chapter, Wildlife 2001: Populations
Information on change in population size over time is among the most basic inputs for population management. Unfortunately, population changes are generally difficult to identify, and once identified difficult to explain. Sources of variald (patterns) in population data include: changes in environment that affect carrying capaciyy and produce...

A comparison of the nesting success of mourning doves and American robins in conventionally managed and organic orchards
K.M. Fluetsch
1992, Book
A comparative study was undertaken to document more closely the effects of operational pesticide use on non-target avian species. Mourning Dove (Zenaida macroura) and American Robin (Turdus migratorius) nesting activity was monitored in three organic and three conventional orchards during two breeding seasons. Surveys were conducted to characterize...

A statistical overview of mass movement characteristics on the North American Atlantic outer continental margin
James S. Booth, Dennis W. O'Leary
1992, Marine Geotechnology (10) 1-18
An analysis of 179 mass movements on the North American Atlantic continental slope and upper rise shows that slope failures have occurred throughout the geographic extent of the outer margin. Although the slope failures show no striking affinity for a particular depth as an origination level, there is a broad,...

Increasing rates of atmospheric mercury deposition in midcontinental North America
Edward B. Swain, Daniel R. Engstrom, Mark E. Brigham, Thomas A. Henning, P.L. Brezonik
1992, Science (257) 784-787
Mercury contamination of remote lakes has been attributed to increasing deposition of atmospheric mercury, yet historic deposition rates and inputs from terrestrial sources are essentially unknown. Sediments of seven headwater lakes in Minnesota and Wisconsin were used to reconstruct regional modern and preindustrial deposition rates of mercury. Whole-basin mercury fluxes,...
