Terrestrial pesticide exposure of amphibians: An underestimated cause of global decline?
TLDR
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.
Impact of Pesticides on Amphibians: A Review
TLDR
Several pesticides show influence on meta morphological stages and prevent larval development, which reduces the rate of growth in amphibian and decline their population, which is needed to reduce the population decline of amphibian globally.
Environmental Toxicology and Chemistry
Amphibians are declining worldwide, in part because of large‐scale degradation of habitat from agriculture and pervasive pathogens. Yet a common North American amphibian, the wood frog (Lithobates
Assessing the links among environmental contaminants, endocrinology, and parasites to understand amphibian declines in montane regions of Costa Rica
TLDR
The results suggest that montane populations of this species are not at greater risk of exposure to contaminants or chronic stress, but implicate nematodes and compromised sex steroid levels as potential threats tomontane populations.
Amphibians at risk? Susceptibility of terrestrial amphibian life stages to pesticides
TLDR
It is demonstrated that cutaneous absorption of chemicals is significant and that chemical percutaneous passage, P (cm/h), is higher in amphibians than in mammals, and the reported data indicate the need for further research, especially in light of the global amphibian decline.
Investigating the effects of organic pollutants on amphibian populations in the UK
TLDR
Data reported in this study confirm the use of ATR-FTIR spectroscopy as a sensitive technique capable of detecting small changes in cellular groups, and as such represents a valuable starting point for its use in the monitoring of amphibian populations.
Amphibians, Pesticides, and the Amphibian Chytrid Fungus in Restored Wetlands in Agricultural Landscapes
TLDR
A negative relationship between Bd zoospore abundance in water and neonicotinoid concentrations in surface water is observed, which can be important contributors to a more complete understanding of the complex and potentially synergistic relationships between disease and pesticides.

Toxicity of herbicide formulations to frogs and the implications for product registration: A case study from Western Australia
TLDR
Research in Western Australia has highlighted the potential risk that agricultural chemicals may pose to fauna that inhabit low dilution environments, and indicates that the data currently required for pre-registration assessment of pesticides may be inadequate to effectively protect these environments.
Possible interrelations among environmental toxicants, amphibian development, and decline of amphibian populations.
TLDR
The potential roles of toxicants in affecting the susceptibility of young to disease, retarding growth and development of amphibian young, and directly causing mortality of young are examined.
Complexity in conservation: lessons from the global decline of amphibian populations
TLDR
It is argued that amphibian population declines are caused by different abiotic and biotic factors acting together in a context-dependent fashion, and different species and different populations of the same species may react in different ways to the same environmental insult.
Effects of Atrazine on Fish, Amphibians, and Aquatic Reptiles: A Critical Review
TLDR
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.
Ultraviolet radiation, toxic chemicals and amphibian population declines
TLDR
This paper reviews the contribution of increasing UV radiation and environmental contamination to the global decline of amphibian populations and suggests synergy interactions of UV radiation with contaminants can enhance the detrimental effects of the contaminant and UV radiation.
Species- and Age-Related Differences in Susceptibility to Pesticide Exposure for Two Amphibians, Rana pipiens, and Bufo americanus
TLDR
Pesticides may be used throughout the growing season on many crops, but generally a particular formulation is only applied during an abbreviated time window of pest abundance and so will likely only directly interact with one or two amphibian morphologies.
Pesticide Mixtures, Endocrine Disruption, and Amphibian Declines: Are We Underestimating the Impact?
TLDR
Estimating ecological risk and the impact of pesticides on amphibians using studies that examine only single pesticides at high concentrations may lead to gross underestimations of the role of pesticides in amphibian declines.
PESTICIDES AND AMPHIBIANS: THE IMPORTANCE OF COMMUNITY CONTEXT
TLDR
An outdoor mesocosm experiment on aquatic communities containing three tadpole species, zooplankton, and algae found that pesticides can have both direct and indirect effects in natural communities and that these effects critically depend upon the composition of the community.
Effects of agricultural pesticides on the immune system of Xenopus laevis and Rana pipiens.
Global Amphibian Declines: A Problem in Applied Ecology
TLDR
The results suggest that most amphibian populations should decrease more often than they increase, due to highly variable recruitment and less variable adult mortality.
