“…The bioavailability and toxicity of POPs and pesticides in wildlife is likely to increase in response to rising temperatures and salinity (Boone and Bridges, 1999;Capkin et al, 2006;Gaunt and Barker, 2000;Heugens et al, 2001;Moore et al, 2003;Schiedek et al, 2007;Silbergeld, 1973;Song and Brown, 1998;Tachikawa and Sawamura, 1994;Wang et al, 2001;Waring and Moore, 2004). An underlying mechanism of this interactive toxicity is that temperature alters the toxicokinetics of chemical pollutants in exposed biota (Buchwalter et al, 2003;Lydy et al, 1999;Maruya et al, 2005).…”

“…The toxicity of contaminants may be enhanced with increasing temperatures (Boone and Bridges, 1999;Capkin et al, 2006;Gaunt and Barker, 2000;Silbergeld, 1973). While the exact mechanisms underlying this relationship are not fully understood and the majority of research focuses on aquatic species, studies indicate that temperature-induced shifts in metabolism are one controlling factor (Buckman et al, 2007;Lydy et al, 1999;Monserrat and Bianchini, 1995).…”

“…In the green frog (Rana clamitans), the toxicity of the insecticide carbaryl increased with temperature increases from 17°C to 22°C to 27°C (Boone and Bridges, 1999). Gaunt and Barker (2000) found that the toxicity of the herbicide atrazine to catfish (Ictalurus punctatus) increased with increasing temperature or decreasing dissolved oxygen.…”

Climate change induced by anthropogenic warming of the earth's atmosphere is a daunting problem. This review examines one of the consequences of climate change that has only recently attracted attention: namely, the effects of climate change on the environmental distribution and toxicity of chemical pollutants. A review was undertaken of the scientific literature (original research articles, reviews, government and intergovernmental reports) focusing on the interactions of toxicants with the environmental parameters, temperature, precipitation, and salinity, as altered by climate change. Three broad classes of chemical toxicants of global significance were the focus: air pollutants, persistent organic pollutants (POPs), including some organochlorine pesticides, and other classes of pesticides. Generally, increases in temperature will enhance the toxicity of contaminants and increase concentrations of tropospheric ozone regionally, but will also likely increase rates of chemical degradation. While further research is needed, climate change coupled with air pollutant exposures may have potentially serious adverse consequences for human health in urban and polluted regions. Climate change producing alterations in: food webs, lipid dynamics, ice and snow melt, and organic carbon cycling could result in increased POP levels in water, soil, and biota. There is also compelling evidence that increasing temperatures could be deleterious to pollutant-exposed wildlife. For example, elevated water temperatures may alter the biotransformation of contaminants to more bioactive metabolites and impair homeostasis. The complex interactions between climate change and pollutants may be particularly problematic for species living at the edge of their physiological tolerance range where acclimation capacity may be limited. In addition to temperature increases, regional precipitation patterns are projected to be altered with climate change. Regions subject to decreases in precipitation may experience enhanced volatilization of POPs and pesticides to the atmosphere. Reduced precipitation will also increase air pollution in urbanized regions resulting in negative health effects, which may be exacerbated by temperature increases. Regions subject to increased precipitation will have lower levels of air pollution, but will likely experience enhanced surface deposition of airborne POPs and increased run-off of pesticides. Moreover, increases in the intensity and frequency of storm events linked to climate change could lead to more severe episodes of chemical contamination of water bodies and surrounding watersheds. Changes in salinity may affect aquatic organisms as an independent stressor as well as by altering the bioavailability and in some instances increasing the toxicity of chemicals. A paramount issue will be to identify species and populations especially vulnerable to climate-pollutant interactions, in the context of the many other physical, chemical, and biological stressors that will be altered with climate change. Moreover, it w...

“…Abiotic factors such as pH, temperature, and light can synergistically affect mortality caused by pesticides (14)(15)(16)), but we know little about the potential synergistic effects of biotic factors. For example, the fear of predation is a common stressor that causes most animals, including amphibians, to become less active and grow more slowly (17)(18)(19)(20)(21)(22), but there appear to be no studies that have examined the interaction between predator-induced fear and pesticides as multiple stressors.…”

Global declines in amphibians likely have multiple causes, including widespread pesticide use. Our knowledge of pesticide effects on amphibians is largely limited to short-term (4-d) toxicity tests conducted under highly artificial conditions to determine lethal concentrations (LC50). We found that if we used slightly longer exposure times (10 -16 d), low concentrations of the pesticide carbaryl (3-4% of LC50 4-d) killed 10 -60% of gray treefrog (Hyla versicolor) tadpoles. If predatory cues also were present, the pesticide became 2-4 times more lethal, killing 60 -98% of tadpoles. Thus, under more realistic conditions of increased exposure times and predatory stress, current application rates for carbaryl can potentially devastate gray treefrog populations. Further, because predator-induced stress is ubiquitous in animals and carbaryl's mode of action is common to many pesticides, these negative impacts may be widespread in nature.

Changes in percentage of forest cover can influence nutrient levels in aquatic systems and change abiotic conditions that may influence species. The authors examined how increasing amounts of leaf litter influenced toxicity of the insecticide carbaryl using larval green frogs (Rana clamitans) in outdoor mesocosm ponds. Insecticides can have direct negative effects on individual physiology and behavior and indirect effects on the food web, which can result in trophic cascades. They predicted that direct effects of the insecticide would dominate when nutrients were low (resulting in negative impacts on amphibian development and survival), whereas indirect effects could offset direct effects when nutrients were more abundant through a trophic cascade that leads to more food for tadpoles (resulting in positive effects on amphibian development and survival). The authors found support for this hypothesis: first, total green frog survival was greatest with increased leaf litter input in the presence of carbaryl. Additionally, most green frogs that reached metamorphosis were from ponds with high leaf litter input and carbaryl. Second, the impact of carbaryl on developmental stage and tadpole mass varied depending on the amount of leaf litter present. With high amounts of leaf litter, carbaryl had a positive impact on development and growth; in contrast, with low amounts of leaf litter, carbaryl had negative or no effects on tadpole development and mass. The present study suggests that differences in nutrient levels between ponds exposed to pesticides could play a role in amphibian population dynamics.
