Capture-Recapture: Parameter Estimation for Open Animal Populations

This comprehensive book, rich with applications, offers a quantitative framework for the analysis of the various capture-recapture models for open animal populations, while also addressing associated computational methods. The state of our wildlife populations provides a litmus test for the state of our environment, especially in light of global warming and the increasing pollution of our land, seas, and air. In addition to monitoring our food resources such as fisheries, we need to protect endangered species from the effects of human activities (e.g. rhinos, whales, or encroachments on the habitat of orangutans). Pests must be be controlled, whether insects or viruses, and we need to cope with growing feral populations such as opossums, rabbits, and pigs. Accordingly, we need to obtain information about a given population’s dynamics, concerning e.g. mortality, birth, growth, breeding, sex, and migration, and determine whether the respective population is increasing , static, or declining. There are many methods for obtaining population information, but the most useful (and most work-intensive) is generically known as “capture-recapture,” where we mark or tag a representative sample of individuals from the population and follow that sample over time using recaptures, resightings, or dead recoveries. Marks can be natural, such as stripes, fin profiles, and even DNA; or artificial, such as spots on insects. Attached tags can, for example, be simple bands or streamers, or more sophisticated variants such as radio and sonic transmitters. To estimate population parameters, sophisticated and complex mathematical models have been devised on the basis of recapture information and computer packages. This book addresses the analysis of such models. It is primarily intended for ecologists and wildlife managers who wish to apply the methods to the types of problems discussed above, though it will also benefit researchers and graduate students in ecology. Familiarity with basic statistical concepts is essential.

The 30th North Carolina Infantry in the Civil War

At the outbreak of the Civil War, the men of the 30th North Carolina rushed to join the regiment, proclaiming, "we will whip the Yankees, or give them a right to a small part of our soil--say 2 feet by 6 feet." Once the Tar Heels experienced combat, their attitudes changed. One rifleman recorded: "We came to a Yankee field hospital ... we moved piles of arms, feet, hands." By 1865, the unit's survivors reflected on their experiences, wondering "when and if I return home--will I be able to fit in?" Drawing on letters, journals, memoirs and personnel records, this history follows the civilian-soldiers from their mustering-in to the war's final moments at Appomattox. The 30th North Carolina had the distinction of firing at Abraham Lincoln on July 12, 1864, as the president stood upon the ramparts of Ft. Stevens outside Washington, D.C., and firing the last regimental volley before the surrender of the Army of Northern Virginia.
