“…In addition, tadpoles from Green Island exposed to intermediate salinity (3 ppt) were larger than those in freshwater and higher salinities (5, 7, and 9 ppt). Earlier studies have suggested that increased tadpole growth in situations of intermediate stress may result from an overcompensated response to stress, but the response will be limited when the stress is too high (Smith et al, 2004;Chinathamby et al, 2006). Salinity at 9 ppt also significantly decreased the percent of F. limnocharis tadpoles undergoing metamorphosis, and only a few tadpoles reached metamorphosis.…”

We studied salinity tolerance and the effects of salinity on growth, development, and metamorphosis in Fejervarya limnocharis tadpoles living in brackish water. Specifically, we examined whether tadpoles exhibit adaptive plasticity in development when exposed to different salinities. Tadpoles collected on Green and Orchid Islands off Southeastern Taiwan were assigned to salinities of 0, 3, 5, 7, 9, 11, and 13 parts per thousand (ppt). The daily survival, weekly growth, and development of tadpoles were recorded until metamorphosis. More than 50% of tadpoles survived in 9 ppt for over a month, and a few individuals survived in 11 ppt for 20 days, suggesting that F. limnocharis tadpoles tolerate salinity better than the tadpoles of most species studied to date. Tadpoles at 9 ppt had lower survivorship, and retarded growth and development (from Gosner stage 26 to 35) compared to the other treatments. Tadpoles metamorphosed early at a smaller size as salinity increased, suggesting the existence of adaptive developmental plasticity in F. limnocharis in response to osmotic stress. Phenotypic plasticity in the age and size at metamorphosis in response to salinity may provide a means for tadpoles to adapt to the unpredictable salinity variation in coastal rock pools.

“…These results suggest that nitrite could indirectly increase amphibian mortality from predators and the environment through sublethal effects on hatching, growth, and development. As the amount of nitrogen entering aquatic ecosystems continues to increase (Bumb and Baanante 1996;National Atmospheric Deposition Program 2005), more ephemeral pools may develop increased nitrite concentrations, potentially causing or increasing population declines in amphibians through both lethal (Huey and Beitinger 1980a;Smith et al 2004;Griffis-Kyle 2005) and sublethal pathways.…”

“…Nitrite can cause direct lethal effects in amphibians (Huey and Beitinger 1980a;Smith et al 2004;Griffis-Kyle 2005), but the sublethal effects, especially on amphibians that breed in ephemeral ponds in agricultural regions, need to be explored. Hatching variability and growth and development of embryos and larvae of the eastern tiger salamander (Ambystoma tigrinum tigrinum) and the wood frog (Rana sylvatica) collected from ephemeral ponds in an agricultural area in Minnesota were examined to accomplish this.…”

Ephemeral pools, which can have high animal biomass and low dissolved oxygen, may be prone to nitrite accumulation. As such, it is important to understand how exposure to nitrite might affect development and growth of amphibians that breed in these ephemeral pools. Wood frog (Rana sylvatica) and eastern tiger salamander (Ambystoma tigrinum tigrinum) embryos and tadpoles and young larvae were exposed to elevated concentrations of nitrite derived from sodium nitrite: 0, 0.3, 0.6, 1.2, 2.1, 4.6, and 6.1 mg l -1 NO 2 -N. Increasing nitrite exposure slowed embryonic and larval development in both the eastern tiger salamander and the wood frog, reduced growth in tiger salamander embryos and larvae, and delayed metamorphosis in the wood frog. At concentrations less than 2 mg l -1 NO 2 -N nitrite delayed hatching, and at concentrations above 2 mg l -1 time to hatching decreased causing more individuals to hatch at less developed stages. Nitrite also increased asynchrony in tiger salamander hatching. The sublethal effects of nitrite on amphibian development, growth and hatching could have serious repercussions on amphibian fitness in ephemeral environments. Potential increases in mortality on field populations caused by sublethal effects of nitrite are discussed.
