Common terns (Sterna hirundo) and roseate terns (Sterna dougallii) breed on Bird Island, Massachusetts, USA, near a Superfund site highly contaminated with polychlorinated biphenyls (PCBs). Observations of skewed sex ratios and female–female pairings among endangered roseate terns (Nisbet and Hatch (1999) Ibis141, 307) suggested the possibility of contaminant-related endocrine disruption in these birds and prompted investigation of common terns as a surrogate species. In 1993 and 1994, 60–90… Expand
Effects on the reproductive system in domestic dowl (Gallus domesticus) after embryonic exposure to estrogenic substances
TLDR
Embryonic exposure of domestic fowl to o,p´-DDT or EE2 resulted in persistent malformations of the reproductive organs of both sexes, with eggshell thinning and reduced semen production as a consequence, which provides a possible explanation for how egg shell thinning may be induced in wild birds. Expand
Pituitary-gonadal axis and secondary sex characters in the spontaneously masculinized pintail, Anas acuta (Anatidae, Aves), with special regard to the gonadotrophs.
TLDR
This paper describes some aspects of the pituitary gland, gonads, and secondary sex characters of unusual pintails, Anas acuta, found in the wild, found to be females with partially masculinized plumage, which showed various degrees of intersex. Expand
Integrating Monitoring and Genetic Methods To Infer Historical Risks of PCBs and DDE to Common and Roseate Terns Nesting Near the New Bedford Harbor Superfund Site (Massachusetts, USA).
TLDR
The approach demonstrates how comparative genetics at target loci can effectively increase the range of inference for chemical risk assessments from tested to untested and untestable species. Expand
Endocrine disruption and altered sexual development in aquatic organisms: an invertebrate perspective
  • W. Langston
  • Biology
  • Journal of the Marine Biological Association of the United Kingdom
  • 2020
TLDR
In view of the recent general declines in marine biodiversity, and the potential contribution of ED-like phenomena, safeguarding against deleterious effects through increased research which links pollutant exposure with reproductive dysfunction among invertebrates, is seen as a high priority. Expand
PCBs and DDE in tree swallow (Tachycineta bicolor) eggs and nestlings from an estuarine PCB superfund site, New Bedford Harbor, MA, U.S.A.
TLDR
Like some highly contaminated freshwater sites, NBH PCB bioaccumulation had little apparent effect on reproductive success, and PCB homologue patterns linked tree swallow contamination to NBH sediment. Expand
Roles of ERα and ERβ in Normal and Disrupted Sex Differentiation in Japanese Quail
TLDR
It is suggested that oestrogen-induced disruption of reproductive organ development in Japanese quail can be mediated via ER alpha, whereas the role of ER alpha in demasculinisation of copulatory behaviour remains to be clarified. Expand
Subtle sabotage: endocrine disruption in wild populations
TLDR
Although endocrine disruption will rarely be the sole cause of failing recruitment or decreased abundance, it may subtly sabotage sexual development, sex ratio, and metabolic compensation for environmental stress, which in combination with other stressors such as habitat loss, over-harvesting, and global climate change, may contribute to local extinctions. Expand
Interspecies Comparison of Chlorinated Contaminant Concentrations and Profiles in Wild Terrestrial Mammals from Northwest Poland
TLDR
The obtained results show that the levels of residues of most of the analyzed compounds were greater in omnivorous mammals than herbivory mammals, and differences in the pattern of accumulation of organochlorines were found. Expand
S0025315420000533jrv 495..515
Contaminants causing sex-altering, endocrine disrupting-like (ED) effects, or otherwise influencing reproduction, have been of growing concern to humans for more than 50 years. They have also been aExpand
Effects of Endocrine Modulators on Sex Differentiation in Birds
TLDR
Data reviewed in this paper are mostly from laboratory studies on endocrine modulators with oestrogenic activity, whereas evidence for adverse effects of pollutants on sexual differentiation in avian wildlife is scarce. Expand

Feminization in common terns (Sterna hirunda) : relationship to persistent organic contaminants
TLDR
Total PCBs and bioassay-derived dioxin equivalents were significantly higher in Bird Island tern embryo yolk sacs than those from Nauset, but were highly variable at both sites, and the relationship between environmental contaminants and ovotestes development was examined. Expand
Feminization of Male Common Tern Embryos Is Not Correlated with Exposure to Specific PCB Congeners
TLDR
An exploratory study of wild common terns in Buzzards Bay, Massachusetts sought to correlate gonadal pathology in embryos with tissue residues of selected chlorobiphenyls to elucidate critical exposures and cause-effect linkages. Expand
Hatching failure in common terns (Sterna hirundo) in relation to environmental chemicals.
TLDR
Eggs of Common Terns breeding at the Elbe estuary had concentrations of some contaminants reaching levels endangering breeding success, and seven out of 45 PCB-congeners were found in significantly higher amounts in the failed eggs. Expand
Effects of PCDDs, PCDFs and PCBs in common tern (sterna hirundo) breeding in estuarine and coastal colonies in the netherlands and belgium
TLDR
The residual yolk sacs of the hatchlings from the highly polluted colonies, located in the main sedimentation area of the Rhine and Meuse rivers, contained on average 16 ng TEQ per gram lipid, which was fivefold higher than the concentrations in the reference colony. Expand
Sensitivity of Common Tern (Sterna hirundo) Embryo Hepatocyte Cultures to CYP1A Induction and Porphyrin Accumulation by Halogenated Aromatic Hydrocarbons and Common Tern Egg Extracts
TLDR
It is suggested that common tern embryos may be more susceptible to the CYP1A inducing effects mediated by complex mixtures of environmental contaminants than indicated by their response to individual HAHs. Expand
Maternal steroids and contaminants in common tern eggs: a mechanism of endocrine disruption?
TLDR
The data provided no evidence for a maternal toxicological event that might alter the amount of maternal steroid hormone transferred to eggs, and concentrations of di- and tri-chlorinated biphenyls and steroids in eggs were not related. Expand
Organochlorine residues in common terns and associated estuarine organisms, Massachusetts, USA, 1971–81
TLDR
The geographical patterns in pesticide residue levels were associated both with urban uses and with specific agricultural uses, and concentrations of organochlorines were highest in urban areas (Boston Harbor and Buzzards Bay) and lowest in remote areas (outer Cape Cod). Expand

TLDR
Feminization of the left testis in males proved to be the most sensitive endpoint for estrogenic activity of xenobiotics in Japanese quail embryos, and the quail egg is proposed as a simple in vivo test system for estrogenIC compounds. Expand
Effects of polyhalogenated aromatic hydrocarbons and related contaminants on common tern reproduction: Integration of biological, biochemical, and chemical data
TLDR
In eight Dutch or Belgian common tern colonies, breeding biology and food choice were determined, and 15 second eggs were collected from three-egg clutches for artificial incubation, biochemical analysis and analysis of yolk-sac polyhalogenated hydrocarbon (PHAH) levels and hepatic EROD activity correlated with and later egg laying, prolonged incubation period and smaller eggs and chicks.
