Spatial scale is rarely considered in population-level assessments of contaminant impacts on wild animals; as a result misinterpretation of the relationship between contaminant exposure and population status may occur. We assessed the strength of expression of polychlorinated biphenyl (PCB) exposure effects at local vs. regional spatial scales on population status in five species of waterbirds, “bioaccumulators” often promoted as indicators of contaminant effects in aquatic ecosystems. Our…

Factors influencing legacy pollutant accumulation in alpine osprey: biology, topography, or melting glaciers?
TLDR
Biotic and abiotic factors determining contaminant variability of wildlife in alpine ecosystems are examined, highlighting the importance of understanding how biological processes integrate physical when studying the environmental chemistry of wildlife.
Effects of Contaminants on Reproductive Success of Aquatic Birds Nesting at Edwards Air Force Base, California
TLDR
Estimates of avian reproduction, in conjunction with analyses of eggs and avian foods for contaminant residues, may indicate the potential for negative effects on avian populations.
The spatial extent of contaminants and the landscape scale: An analysis of the wildlife, conservation biology, and population modeling literature
TLDR
This work analyzed the wildlife and conservation biology literature to determine if information on habitat size requirements such as home-range or critical patch size could inform us about the potential for impact at the landscape level from release sites based on the size of the release alone, and determined that evaluating the impact of release size had to be conducted within a contextual basis.

Reproductive ecology of tree swallows (Tachycineta bicolor) with high levels of polychlorinated biphenyl contamination
TLDR
Given the levels of contamination in this population, the success of most Hudson River tree swallows reinforces the importance of understanding interspecific differences in the effects of contaminants.
Ranking terrestrial vertebrate species for utility in biomonitoring and vulnerability to environmental contaminants.

TLDR
A Utility Index that ranks terrestrial vertebrate species as potential sentinels of contaminants in a region and a Vulnerability Index that assesses the threat of specific groups of contaminants to these species, have been developed to assist decision makers in risk assessments of persistent organic pollutants, cholinesterase-inhibiting pesticides, petroleum crude oil, mercury, and lead shot.
Exposure and effects of chemical contaminants on tree swallows nesting along the Housatonic River, Berkshire County, Massachusetts, USA, 1998-2000.
TLDR
Hatching success of tree swallows was assessed for three years in relation to chemical contamination along the Housatonic River, Berkshire County (MA, USA), in 1998, 1999, and 2000, and a significant negative relationship was observed between concentrations of total PCBs in clutches and hatching success.

TLDR
Improved monitoring and modeling of large-scale boreal forest bird distribution dynamics will be necessary to resolve existing uncertainties, especially on less-common species.
Satellite telemetry and prey sampling reveal contaminant sources to Pacific Northwest Ospreys.
TLDR
Concentrations of p,p'-DDE, were predicted by breeding sites with highest levels in eggs of Ospreys breeding in the lower Columbia River, consistent with published reports of continued high concentrations of DDT and related compounds in that system.
