description How important is endocrine disruption as a threat to wildlife populations? This review applies causal criteria to existing studies of wild populations of fish, amphibians, reptiles, birds, and mammals to answer three questions: (1) Have endocrine-mediated effects of contaminant exposure been documented? (2) Have individual adverse effects that could lead to population effects been documented? (3) Have population level effects been documented? In fish, the possibility of population level effects is inferred from impaired individual fertility. Substantial evidence directly links fertility impairment to endocrine disruption. In amphibians, population declines are occurring worldwide and causes may vary among regions, with contaminant-induced sexual disruption being one of many insults that stymie population growth. In reptiles, local populations of alligators have been dramatically reduced by direct toxicity and recovery has probably been slowed by sexual disruption, particularly feminization induced by chronic contaminant exposure. In contrast, heavily contaminated snapping turtles display feminized secondary sex characteristics, evidence of disrupted sexual development, but populations are densest at the most heavily contaminated site. In birds, population decline and recovery have been directly linked to p,p’-DDE-mediated eggshell thinning and subsequent banning of the parent compound DDT in the US and Europe. Regional populations of predatory birds still suffer chick mortality related to PCB and DDT burdens, but no causal link with endocrine-mediated processes has been demonstrated. In mammals, contaminant- induced hormonal derangements in seals and polar bears have been documented, but no clear evidence links endocrine effects to population declines. 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. Endocrine disruption is unlikely to extirpate a species over its entire range, but in combination with other stressors such as habitat loss, over-harvesting, and global climate change, may contribute to local extinctions.

Epub 2006 Sept. 30.En anfibios, a nivel mundial esta ocurriendo una disminución de las poblaciones y sus causas varían entre regiones, con la disrupción endocrina inducida por contaminantes como una de las causas que frustra el crecimiento poblacional. En reptiles, las poblaciones locales de lagartos han sido reducidas drásticamente por exposición directa a sustancia toxicas y su recuperación ha sido demorada probablemente por disrupción sexual, particularmente por la feminización inducida por exposición crónica a contaminantes. En contraste, tortugas lagarto altamente contaminadas muestran características sexuales secundarias feminizadas, evidencia de desarrollo sexual alterado, pero las poblaciones son más numerosas en los sitios más contaminados. En aves, el decrecimiento de las poblaciones y su recuperación han sido directamente ligadas con la exposición a residuos de p, p-DDE a través del adelgazamiento de la cáscara del huevo y con la prohibición del uso del compuesto DDT en USA y Europa. Aves depredadoras regionales todavía sufren mortalidad de polluelos relacionada con cargas de PCB y DDT, pero no han sido demostrados vínculos causales con procesos mediados via endocrina. En mamíferos, han sido documentados desórdenes hormonales inducidos por contaminantes en focas y osos polares, pero no hay evidencia directa que ligue efectos endocrinos con la disminución de las poblaciones. No obstante que la disrupción endocrina raramente es la única causa de fallos en reclutamiento o disminución de las abundancias, puede ser un saboteador sutil del desarrollo sexual, tasa de sexos, y compensación metabólica ante el estrés ambiental. La disrupción endocrina es poco probable que llegue a extirpar una especie de su ámbito entero, pero en combinación con otros tensores como pérdida de habitat, extracción excesiva, y cambio climático global, podría contribuir a extinciones locales.Universidad de Costa Rica2006-09-01info:eu-repo/semantics/publishedVersionArticleartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdfhttps://revistas.ucr.ac.cr/index.php/rbt/article/view/2682410.15517/rbt.v54i1.26824Revista de Biología Tropical; Vol. 54 No. S1 (2006): Volume 54 – Supplement 1 – September 2006: Aquatic ecosystems of Costa Rica IV; 1–19Revista de Biología Tropical; Vol. 54 Núm.
