Effects of Atrazine on Fish, Amphibians, and Aquatic Reptiles: A Critical Review
Keith R. Solomon,James A. Carr,Louis H. Du Preez,John P. Giesy,Ronald J. Kendall,Ernest E. Smith,Glen Van Der Kraak +6 more
TL;DR: The central theory that environmentally relevant concentrations of atrazine affect reproduction and/or reproductive development in fish, amphibians, and reptiles is not supported by the vast majority of observations.
Journal ArticleDOI
Response of larval Xenopus laevis to atrazine: Assessment of growth, metamorphosis, and gonadal and laryngeal morphology
James A. Carr,Angie Gentles,Ernest E. Smith,Wanda L. Goleman,Lina J. Urquidi,Kerry A. Thuett,Ronald J. Kendall,John P. Giesy,Tim S. Gross,Keith R. Solomon,Glen Van Der Kraak +10 more
TL;DR: It is concluded that environmentally relevant concentrations of atrazine do not influence metamorphosis or sex ratios and do not inhibit sexually dimorphic larynx growth in X. laevis.
Journal ArticleDOI
The hypothalamus-pituitary-thyroid axis in teleosts and amphibians: endocrine disruption and its consequences to natural populations.
James A. Carr,Reynaldo Patiño +1 more
TL;DR: There is no evidence to clearly link contaminant-induced HPT alterations to impairments in teleost or amphibian population health in the field, and future field studies should focus on establishing temporal associations between the presence of HPT-disrupting chemicals, the occurrence ofHPT alterations, and adverse effects on development and reproduction in natural populations.
Journal ArticleDOI
Environmentally relevant concentrations of ammonium perchlorate inhibit thyroid function and alter sex ratios in developing Xenopus laevis.
TL;DR: It is concluded that AP inhibits thyroid activity and alters gonadal differentiation in developing X. laevis, suggesting that this contaminant may pose a threat to normal development and growth in natural amphibian populations.
Journal ArticleDOI
I'll take the low road: The evolutionary underpinnings of visually triggered fear
TL;DR: Comparative studies shed light not only on how fear triggering visual pathways came to be, but how hormones released as a result of this activation modulate these pathways.
