Journal ArticleDOI
Wildlife Ecotoxicology of Pesticides: Can We Track Effects to the Population Level and Beyond?
H.-R. Köhler,Rita Triebskorn +1 more
TL;DR: In these times of regional and global species declines, the task of causally linking knowledge about the molecular actions of pesticides to their possible interference with biological processes is challenged in order to develop reliable predictions about the consequences of pesticide use, and misuse, in a rapidly changing world.
Journal ArticleDOI
Glyphosate and Its Degradation Product AMPA Occur Frequently and Widely in U.S. Soils, Surface Water, Groundwater, and Precipitation†
TL;DR: In this paper, a comprehensive assessment of the environmental occurrence of glyphosate and aminomethylphosphonic acid (AMPA) in the United States conducted to date, summarizing the results of 3,732 water and sediment and 1,018 quality assurance samples collected between 2001 and 2010 from 38 states.
Journal ArticleDOI
Terrestrial pesticide exposure of amphibians: An underestimated cause of global decline?
TL;DR: The demonstrated toxicity is alarming and a large-scale negative effect of terrestrial pesticide exposure on amphibian populations seems likely, calling for more attention in conservation efforts.
Book ChapterDOI
The Hidden and External Costs of Pesticide Use
Denis Bourguet,Thomas Guillemaud +1 more
TL;DR: In this paper, the authors provide a comprehensive review of these costs and their evaluation and define four categories of costs: regulatory costs, human health costs, environmental costs and defensive expenditures.
Journal ArticleDOI
Questions concerning the potential impact of glyphosate‐based herbicides on amphibians
TL;DR: The authors recommend better monitoring of both amphibian populations and contamination of habitats with glyphosate-based herbicides, not just glyphosate, and suggest including amphibians in standardized test batteries to study at least dermal administration.

Status and Trends of Amphibian Declines and Extinctions Worldwide
Simon N. Stuart,Janice Chanson,Neil A. Cox,Bruce E. Young,Ana S. L. Rodrigues,Debra L. Fischman,Robert W. Waller +6 more
TL;DR: The first global assessment of amphibians provides new context for the well-publicized phenomenon of amphibian declines and shows declines are nonrandom in terms of species' ecological preferences, geographic ranges, and taxonomic associations and are most prevalent among Neotropical montane, stream-associated species.
Journal ArticleDOI
Chytridiomycosis causes amphibian mortality associated with population declines in the rain forests of Australia and Central America.
Lee Berger,Richard Speare,Peter Daszak,D.E. Green,Andrew A. Cunningham,C. L. Goggin,R Slocombe,Mark A. Ragan,Alex D. Hyatt,Keith R. McDonald,Harry B. Hines,Karen R. Lips,Gerry Marantelli,H. Parkes +13 more
TL;DR: Experimental data support the conclusion that cutaneous chytridiomycosis is a fatal disease of anurans, and it is hypothesize that it is the proximate cause of these recent amphibian declines.

Ecological and toxicological effects of inorganic nitrogen pollution in aquatic ecosystems: A global assessment.
Julio A. Camargo,Álvaro Alonso +1 more
TL;DR: In this article, a global assessment of the effects of inorganic nitrogen pollution in aquatic ecosystems is presented, with detailed multi-scale data, and three major environmental problems: (1) increasing the concentration of hydrogen ions in freshwater ecosystems without much acid-neutralizing capacity, resulting in acidification of those systems; (2) stimulating or enhancing the development, maintenance and proliferation of primary producers, leading to eutrophication of aquatic ecosystems; (3) reaching toxic levels that impair the ability of aquatic animals to survive, grow and reproduce.

Hermaphroditic, demasculinized frogs after exposure to the herbicide atrazine at low ecologically relevant doses.
Tyrone B. Hayes,Atif Collins,Melissa Lee,Magdelena Mendoza,Nigel C. Noriega,A Ali Stuart,Aaron Vonk +6 more
TL;DR: It is hypothesize that atrazine induces aromatase and promotes the conversion of testosterone to estrogen and likely explains the demasculinization of the male larynx and the production of hermaphrodites.
