Limits on the adaptability of coastal marshes to rising sea level Limits on the adaptability of coastal marshes to rising sea level
Assumptions of a static landscape inspire predictions that about half of the world's coastal wetlands will submerge during this century in response to sea-level acceleration. In contrast, we use simulations from five numerical models to quantify the conditions under which ecogeomorphic feedbacks allow coastal wetlands to adapt to projected changes in sea level. In contrast to previous...

Standards for documenting and monitoring bird reintroduction projects Standards for documenting and monitoring bird reintroduction projects
It would be much easier to assess the effectiveness of different reintroduction methods, and so improve the success of reintroductions, if there was greater standardization in documentation of the methods and outcomes. We suggest a series of standards for documenting and monitoring the methods and outcomes associated with reintroduction projects for birds. Key suggestions are...

Evaluating propagation method performance over time with Bayesian updating: An application to incubator testing Evaluating propagation method performance over time with Bayesian updating: An application to incubator testing
In captive-rearing programs, small sample sizes can limit the quality of information on performance of propagation methods. Bayesian updating can be used to increase information on method performance over time. We demonstrate an application to incubator testing at USGS Patuxent Wildlife Research Center. A new type of incubator was purchased for use in the whooping crane (Grus americana)

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 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...

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...

Predictors of occurrence of the aquatic macrophyte Podostemum ceratophyllum in a southern Appalachian River Predictors of occurrence of the aquatic macrophyte Podostemum ceratophyllum in a southern Appalachian River
The aquatic macrophyte Podostemum ceratophyllum (Hornleaf Riverweed) commonly provides habitat for invertebrates and fishes in flowing-water portions of Piedmont and Appalachian streams in the eastern US. We quantified variation in percent cover by P. ceratophyllum in a 39-km reach of the Conasauga River, TN and GA, to test the hypothesis that cover decreased with increasing non-forest...

Intraperitoneal injections as a possible means of generating varied levels of methylmercury in the eggs of birds in field studies Intraperitoneal injections as a possible means of generating varied levels of methylmercury in the eggs of birds in field studies
The ideal study of the effects of methylmercury on the reproductive success of a species of bird would be one in which eggs contained mercury concentrations ranging from controls to very heavily contaminated, all at the same site. Such a study cannot be realized at a mercury contaminated area or under laboratory conditions, but could be achieved by introducing methylmercury into breeding...

Certhiasomus, a new genus of woodcreeper (Aves: Passeriformes: Dendrocolaptidae) Certhiasomus, a new genus of woodcreeper (Aves: Passeriformes: Dendrocolaptidae)
Phylogenetic analysis of the family Dendrocolaptidae (Aves: Passeriformes) indicates that the two species traditionally placed in the genus Deconychura are not sister taxa. Certhiasomus, a new genus of woodcreeper, is described for one of these species, C. stictolaemus.
