white-tailed eagle (haliaeetus albicilla) and great cormorant (phalacrocorax carbo) nestlings as spatial sentinels of baltic acidic sulphate soil associated metal contamination.	sulphate soils, characterised by low ph conditions, are found worldwide, and are potentially large sources of metal contamination, often exceeding industrial emissions. metal leaching from sulphate soils has been shown to be harmful to aquatic organisms, but the cascading effect on exposure in apex avian predators has not been studied earlier. with the present study we aimed at evaluating the potential of white-tailed eagle (haliaeetus albicilla) and great cormorant (phalacrocorax carbo) nestlin ...	2020	32325615
current situation regarding lead exposure in birds in japan (2015-2018); lead exposure is still occurring.	birds of a number of species have died as a result of lead (pb) poisoning, including many steller's sea eagles (haliaeetus pelagicus) and white-tailed sea eagles (haliaeetus albicilla) in hokkaido, the northernmost island of japan. to address this issue, the use of any type of pb ammunition for hunting of large animals was prohibited in hokkaido in 2004. however, pb poisoning is still being reported in this area, and there are few regulations regarding the use of pb ammunition in other parts of ...	2020	32554936
a novel use of the leukocyte coping capacity assay to assess the immunomodulatory effects of organohalogenated contaminants in avian wildlife.	apex predators are characterized by high levels of biomagnifying organohalogenated contaminants (ohcs) which have been found to induce detrimental health effects in wildlife, such as immune system impairment. the leukocyte coping capacity (lcc) assay is a functional real-time measure of an innate immune response essential in pathogen resistance, known as the respiratory burst. the current study suggests the novel use of this tool to test whether ohcs impair the innate immune system of a sentinel ...	2020	32563774
high-resolution modeling of uplift landscapes can inform micrositing of wind turbines for soaring raptors.	collision risk of soaring birds is partly associated with updrafts to which they are attracted. to identify the risk-enhancing landscape features, a micrositing tool was developed to model orographic and thermal updraft velocities from high-resolution remote sensing data. the tool was applied to the island of hitra, and validated using gps-tracked white-tailed eagles (haliaeetus albicilla). resource selection functions predicted that eagles preferred ridges with high orographic uplift, especiall ...	2020	32577874
body mass, mercury exposure, biochemistry and untargeted metabolomics of incubating common eiders (somateria mollissima) in three baltic colonies.	the baltic/wadden sea flyway of common eiders has declined over the past three decades. multiple factors such as contaminant exposure, global warming, hunting, white-tailed eagle predation, decreased agricultural eutrophication and infectious diseases have been suggested to explain the decline. we collected information on body mass, mercury (hg) concentration, biochemistry and untargeted metabolomics of incubating birds in two colonies in the danish straits (hov røn, n = 100; agersø, n = 29) and ...	2020	32590281
bioaccumulation potential of bisphenols and benzophenone uv filters: a multiresidue approach in raptor tissues.	environmental exposure to bisphenols and benzophenone uv filters has received considerable attention due to the ubiquitous occurrence of these contaminants in the environment and their potential adverse health effects. the occurrence of bisphenols and benzophenone uv filters is well established in human populations, but data is scarce for wildlife, and especially for raptors (birds of prey, falcons and owls). in this study, concentrations of eight bisphenols and five benzophenone uv filters were ...	2020	32615426
mortality limits used in wind energy impact assessment underestimate impacts of wind farms on bird populations.	the consequences of bird mortality caused by collisions with wind turbines are increasingly receiving attention. so-called acceptable mortality limits of populations, that is, those that assume that 1%-5% of additional mortality and the potential biological removal (pbr), provide seemingly clear-cut methods for establishing the reduction in population viability.we examine how the application of these commonly used mortality limits could affect populations of the common starling, black-tailed god ...	2020	32724513
organohalogen compounds of emerging concern in baltic sea biota: levels, biomagnification potential and comparisons with legacy contaminants.	while new chemicals have replaced major toxic legacy contaminants such as polychlorinated biphenyls (pcbs) and dichlorodiphenyltrichloroethane (ddt), knowledge of their current levels and biomagnification potential in baltic sea biota is lacking. therefore, a suite of chemicals of emerging concern, including organophosphate esters (opes), short-chain, medium-chain and long-chain chlorinated paraffins (sccps, mccps, lccps), halogenated flame retardants (hfrs), and per- and polyfluoroalkyl substan ...	2020	32835922
paint it black: efficacy of increased wind turbine rotor blade visibility to reduce avian fatalities.	as wind energy deployment increases and larger wind-power plants are considered, bird fatalities through collision with moving turbine rotor blades are expected to increase. however, few (cost-) effective deterrent or mitigation measures have so far been developed to reduce the risk of collision. provision of "passive" visual cues may enhance the visibility of the rotor blades enabling birds to take evasive action in due time. laboratory experiments have indicated that painting one of three roto ...	2020	32884668
new extraction method prior to screening of organic micropollutants in various biota matrices using liquid chromatography coupled to high-resolution time-of-flight mass spectrometry.	a new extraction method with limited clean-up requirements prior to screening various matrices for organic micropollutants using liquid chromatography-high resolution mass spectrometry (lc-hrms) for analysis was developed. first, the performance of three extraction methods (quechers with spe clean-up, ultrasonication with spe clean-up, extraction without spe clean-up) was tested, optimized, and compared using >200 contaminants of emerging concern (cecs) together covering a wide range of physicoc ...	2020	32887036
