Hierarchial mark-recapture models: a framework for inference about demographic processes Hierarchial mark-recapture models: a framework for inference about demographic processes
The development of sophisticated mark-recapture models over the last four decades has provided fundamental tools for the study of wildlife populations, allowing reliable inference about population sizes and demographic rates based on clearly formulated models for the sampling processes. Mark-recapture models are now routinely described by large numbers of parameters. These large models...

Contaminant exposure and reproductive success of Ospreys (Pandion haliaetus) nesting in Chesapeake Bay regions of concern Contaminant exposure and reproductive success of Ospreys (Pandion haliaetus) nesting in Chesapeake Bay regions of concern
The Chesapeake Bay osprey population has more than doubled in size since restrictions were placed on the production and use of DDT and other toxic organochlorine contaminants in the 1970s. Ospreys are now nesting in the most highly polluted portions of the Bay. In 2000 and 2001, contaminant exposure and reproduction were monitored in ospreys nesting in regions of concern, including...

Population dynamics of the California Spotted Owl (Strix occidentalis occidentalis): a meta-analysis Population dynamics of the California Spotted Owl (Strix occidentalis occidentalis): a meta-analysis
We conducted a meta-analysis to provide a current assessment of the population characteristics of California Spotted Owls (Strix occidentalis occidentalis) resident on four study areas in the Sierra Nevada and one study area in southern California. Our meta-analysis followed rigorous a priori analysis protocols, which we derived through extensive discussion during a week-long analysis...

Some consequences of using counts of birds banded as indices to populations Some consequences of using counts of birds banded as indices to populations
In mist-net studies, it is often difficult to use capture-recapture methods to estimate number of birds present. Many investigators use number of birds captured as an index of population size. We investigate the consequences of using indices of bird abundance as surrogates for population size in hypothesis tests. Unless all of the birds present are captured, indices are biased estimates...

Modeling survival and movement of resident giant Canada goose populations in the Atlantic flyway Modeling survival and movement of resident giant Canada goose populations in the Atlantic flyway
Distribution of resident giant Canada geese (Branta canadensis maxima) has changed markedly in the Atlantic Flyway in recent decades. This change may be related to habitat variation or to changes in hunting regulations. We attempt to assess impacts of hunting regulations on survival, movement, and harvest rate of Canada goose populations from Maine to South Carolina. During 15 June-31...

Seasonal methane emissions by diffusion and ebullition from oligohaline marsh environments in coastal Louisiana Seasonal methane emissions by diffusion and ebullition from oligohaline marsh environments in coastal Louisiana
Methane is an important atmospheric greenhouse gas that is emitted from many natural and anthropogenic sources. In order to evaluate the global methane budget, precise data are needed from the diverse sources including coastal wetlands. Over 100 time-series determinations of methane emissions from an oligohaline wetland (brackish marsh) in coastal Louisiana show large variability during...

Forty-fifth supplement to the American Ornithologists' Union Check-list of North American Birds Forty-fifth supplement to the American Ornithologists' Union Check-list of North American Birds
This is the fourth Supplement since publication of the 7th edition of the Check-list of North American Birds (American Ornithologists' Union [AOU] 1998). It summarizes decisions made by the AOU's Committee on Classification and Nomenclature between 1 January 2003 and 31 December 2003.

Mute swans: Natural (?) environmental indicators Mute swans: Natural (?) environmental indicators
The rapid expansion of the Chesapeake Bay's population of feral mute swans (Cygnus olar), coupled with a dramatic Bay-wide decline in submerged aquatic vegetation (SAV), has fueled much of the current debate surrounding the need for a management plan to protect the aquatic food resources that are critical to many species native to the Bay. Crucial to this decision process is a sound...
