“…Jonnalagadda and Rao ( 1996 ) performed a test with Bellamya disimilis and recorded a 96-h LC 50 value of 1800 μg/L, whereas Oliveira-Filho et al ( 2005 ) found 96-h LC 50 values of 120 and 890 μg/L for Biomphalaria tenagophila juveniles and adults, respectively. Greater values were reported, however, for three freshwater snails by Ellis-Tabanor and Hyslop ( 2007 ), who obtained 96-h LC 50 values of 2300, 1740, and 1350 μg/L for Melanoides tuberculata , Thiara granifera , and Planorbella duryi , respectively, whereas Otludil et al ( 2004 ) reported an LC 50 value of 3230 μg/L for Planorbarius corneus .…”

The effect of the pesticide endosulfan on predator–prey interactions between catfish and Schistosoma host snails was assessed in static tank experiments. Hybrid catfish (Clarias gariepinus × C. ngamensis) and Bulinus globosus were subjected to various endosulfan concentrations including an untreated control. The 48- and 96-h LC50 values for catfish were 1.0 and <0.5 µg/L, respectively, whereas the 48- and 96-h LC50 values for snails were 1137 and 810 µg/L. To assess sublethal effects on the feeding of the catfish on B. globosus, endosulfan concentrations between 0.03 and 1.0 µg/L were used. Predation was significantly greater (p < 0.001) in control tanks than in all other treatments. There was progressively decreasing predation with increasing toxicant concentration. Biological control of Schistosoma host snails using fish may be affected in endosulfan-polluted aquatic systems of Southern Africa because it has been found present at concentrations that are indicated to cause lethal effects on the evaluated hybrid catfish and to inhibit the predation of snails by this hybrid catfish.Electronic supplementary materialThe online version of this article (doi:10.1007/s00244-016-0275-7) contains supplementary material, which is available to authorized users.

“…First, snails will often retreat into their shells or leave the water to escape perceived threats (e.g. predation, water quality) which can reduce exposure to stressors, especially chemical stressors (Ellis-Tanabor and Hyslop 2007). Second, snails that appear dead can recover if removed from the stress.…”

High tolerance to abiotic stressors and invasion success of the slow growing freshwater snail, Melanoides tuberculatus

Considerable research has been conducted to determine traits common to invasive species with the goal of predicting, preventing, or managing invasions. The importance of physiological tolerance to abiotic stressors in the ability of invasive species to establish and displace native species has been hypothesized to be important although there are few actual tests of the hypothesis in the literature. In freshwater molluscs it has been suggested that high fecundity is the most important trait for invasion success and that physiological tolerance to abiotic conditions is unlikely to play a significant role. We examined the tolerance to abiotic stressors using a known invasive snail species (Melanoides tuberculatus) that has a much slower growth rate and fecundity than a native species it has displaced (Biomphalaria glabrata). We tested the hypothesis that M. tuberculatus would have significantly greater tolerance to natural and anthropogenic abiotic stressors (cadmium, malathion, temperature extremes, and desiccation) which may provide a mechanism for displacement of B. glabrata. A time-to-event analysis was used to determine relative tolerance between species. M. tuberculatus was significantly more tolerant to the tested abiotic stressors than B. glabrata with the exception of low temperature (5°C). Stress tolerance may partly explain the ability of M. tuberculatus to displace B. glabrata despite having a much lower growth rate and fecundity. These results also suggest that M. tuberculatus is likely to have a strong advantage in disturbed or polluted habitats. Identifying those traits most important for the invasion success of particular species could be used to better inform removal strategies and may allow for improved predictions of invasion potential.
