The effects of chronic cadmium exposure on American toad (Bufo americanus) tadpoles.
نویسندگان
چکیده
American toad (Bufo americanus) tadpoles were exposed to cadmium from shortly after hatching through metamorphosis. Cadmium at 540 microg/L decreased percentage survival and metamorphosis; 5 and 54 microg/L increased growth relative to controls. Amphibians exposed to cadmium as tadpoles may be less tolerant of natural stressors in the terrestrial environment.

Metamorphosis of two amphibian species after chronic cadmium exposure in outdoor aquatic mesocosms.
Amphibian larvae at contaminated sites may experience an alteration of metamorphic traits and survival compared to amphibians in uncontaminated conditions. Effects of chronic cadmium (Cd) exposure on the metamorphosis of American toads (Bufo americanus) and southern leopard frogs (Rana sphenocephala) were determined. The two species were reared separately from shortly after hatching through met...
متن کاملThe tactile-stimulated startle response of tadpoles: acceleration performance and its relationship to the anatomy of wood frog (Rana sylvatica), bullfrog (Rana catesbeiana), and American toad (Bufo americanus) tadpoles.
I described the tactile-stimulated startle response (TSR) of wood frog (Rana sylvatica), bullfrog (Rana catesbeiana), and American toad (Bufo americanus) tadpoles. One purpose was to rank species in terms of maximum acceleration performance. Also, I tested whether anatomical indicators of performance potential were predictive of realized performance. TSRs were elicited in a laboratory setting, ...
متن کاملDiet comparison in three tadpole species, Rana sylvatica, Bufo americanus, and Pseudacris crucifer, in a northern temperate climate
The natural diet of northern temperate tadpoles is a largely neglected area of study. We investigated the natural diets in three anuran larvae, the wood frog (Rana sylvatica), the American toad (Bufo americanus), and the spring peeper (Pseudacris crucifer), from several ephemeral ponds in northern Minnesota. Previous laboratory studies suggest that these species, as well as others with similar ...
متن کاملDevelopmental variation in resistance and tolerance in a multihostparasite system
1. Organisms can protect themselves against parasitism by reducing either parasite burden (resistance) or damage caused by parasites at a given burden (tolerance), but little is known about resistance and tolerance to multiple parasites among wild animal populations and species. The fitness effects of parasitism can be broken down into two components: (i) cost of parasite exposure, the differen...
متن کاملAcute toxicity of maneb in the tadpoles of common and green toad.
Pesticides used in agriculture can have hazardous effects on aquatic organisms, and amphibians are even more threatened than other aquatic vertebrates. Maneb is widely used to control fungal diseases on crops, fruits, and vegetables. The aim of this study was to investigate the acute toxic effects of maneb on the common (Bufo bufo) and green toad (Pseudepidalea viridis) tadpoles. Tadpoles at th...
