Traffic effects on bird counts on North American Breeding Bird Survey routes Traffic effects on bird counts on North American Breeding Bird Survey routes
The North American Breeding Bird Survey (BBS) is an annual roadside survey used to estimate population change in >420 species of birds that breed in North America. Roadside sampling has been criticized, in part because traffic noise can interfere with bird counts. Since 1997, data have been collected on the numbers of vehicles that pass during counts at each stop. We assessed the effect...

The 2003-2008 summary of the North American Breeding Bird Survey The 2003-2008 summary of the North American Breeding Bird Survey
Data from the North American Breeding Bird Survey were used to estimate continental and regional changes in bird populations for the 6-yr period 2003-2008 and the 2-yr period 2007-2008. These short-term changes were placed in the context of population trends estimated over the 1966-2008 interval. Across the entire survey area, a higher proportion of species exhibited positive growth...

Spatially explicit inference for open populations: Estimating demographic parameters from camera-trap studies Spatially explicit inference for open populations: Estimating demographic parameters from camera-trap studies
We develop a hierarchical capture–recapture model for demographically open populations when auxiliary spatial information about location of capture is obtained. Such spatial capture–recapture data arise from studies based on camera trapping, DNA sampling, and other situations in which a spatial array of devices records encounters of unique individuals. We integrate an individual‐based...

Reproduction in mallards exposed to dietary concentrations of methylmercury Reproduction in mallards exposed to dietary concentrations of methylmercury
The purpose of this experiment was to use mallards (Anas platyrhynchos) tested under controlled conditions to determine how much harm to reproduction resulted from various concentrations of mercury in eggs. Breeding pairs of mallards were fed a control diet or diets containing 1, 2, 4, or 8 μg/g mercury, as methylmercury chloride. Mean concentrations of mercury in eggs laid by parents...

The impact of conservation on the status of the world's vertebrates The impact of conservation on the status of the world's vertebrates
Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world's vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds, and amphibians move one category closer to extinction each year. However, this...

Polyphyly of Campylorhamphus, and description of a new genus for C. pucherani (Dendrocolaptinae) Polyphyly of Campylorhamphus, and description of a new genus for C. pucherani (Dendrocolaptinae)
We investigated the phylogenetic relationships of Campylorhamphus pucherani using DNA sequences from three mitochondrial genes and a nuclear intron, as well as 84 morphological characters from the skeleton, the integument, and the musculature. The molecular phylogeny indicated that C. pucherani is not part of Campylorhamphus; instead, it is the sister species to Drymornis bridgesii, in a...

Optimal control of native predators Optimal control of native predators
We apply decision theory in a structured decision-making framework to evaluate how control of raccoons (Procyon lotor), a native predator, can promote the conservation of a declining population of American Oystercatchers (Haematopus palliatus) on the Outer Banks of North Carolina. Our management objective was to maintain Oystercatcher productivity above a level deemed necessary for...

Landscape and vegetation effects on avian reproduction on bottomland forest restorations Landscape and vegetation effects on avian reproduction on bottomland forest restorations
Forest restoration has been undertaken on >200,000 ha of agricultural land in the Mississippi Alluvial Valley, USA, during the past few decades. Decisions on where and how to restore bottomland forests are complex and dependent upon landowner objectives, but for conservation of silvicolous (forest-dwelling) birds, ecologists have espoused restoration through planting a diverse mix of...

Change in avian abundance predicted from regional forest inventory data Change in avian abundance predicted from regional forest inventory data
An inability to predict population response to future habitat projections is a shortcoming in bird conservation planning. We sought to predict avian response to projections of future forest conditions that were developed from nationwide forest surveys within the Forest Inventory and Analysis (FIA) program. To accomplish this, we evaluated the historical relationship between silvicolous...

Genetic introgression and the survival of Florida panther kittens Genetic introgression and the survival of Florida panther kittens
Estimates of survival for the young of a species are critical for population models. These models can often be improved by determining the effects of management actions and population abundance on this demographic parameter. We used multiple sources of data collected during 1982–2008 and a live-recapture dead-recovery modeling framework to estimate and model survival of Florida panther...
