“…Concentrations up to 1,000 mg Cl − /L increase growth, reproduction, and abundance in a ubiquitous pond snail (Physa acuta; Hintz et al, 2017;Kefford & Nugegoda, 2005). Suski, Salice, and Patino (2012) showed that two ubiquitous snail species differed in their susceptibility to NaCl. Ram's horn snails (Helisoma trivolvis) did not reproduce when conductivity was ≥3,000 μS/cm (of NaCl) and they exhibited a 30% reduction in survival at 4,000 μS/cm.…”

Freshwater ecosystems worldwide are threatened by salinisation caused by human activities. Scientific attention on the ecological impacts of salinisation from road deicing salts is increasing exponentially. Spanning multiple trophic levels and ecosystem types, we review and synthesise the ecological impacts of road salt in freshwater ecosystems to understand species‐, community‐, and ecosystem‐level responses. In our review, we identify knowledge gaps that we hope will motivate future research directions. We found that road salts negatively affect species at all trophic levels, from biofilms to fish. The concentration at which road salt triggered an effect varied considerably. Species‐level impacts were generally sub‐lethal, leading to reductions in growth and reproduction, which can be magnified by natural stressors such as predation. Community‐level impacts including reductions of biodiversity were common, leading to communities of salt‐tolerant species, which may have implications for disease transmission from enhanced recruitment of salt‐tolerant host species such as mosquitoes. At the ecosystem level, road salts alter nutrient and energy flow. Contaminated wetlands could see greater export of greenhouse gases, streams will probably export more nitrogen and carbon, and lakes will encounter altered hydrology and oxygen dynamics, leading to greater phosphorus release from sediments. While it is necessary to keep roads safe for humans, the costs to freshwater ecosystems may be severe if actions are not taken to mitigate road salt salinisation. Cooperation among policy makers, environmental managers, transportation professionals, scientists, and the public will be crucial to prevent a loss of ecosystem services including water clarity, drinkable water, recreation venues, and fisheries.

“…Similarly, the observation that during continuous exposure to a pollutant over several generations, developmental anomalies and mortality tend to be aggravated at each additional generation (as in P. acuta exposed to prednisolone, Bal et al (2017)) suggests that poor parental condition is transmitted to the next generation through egg quality, resulting in cumulative toxicity over generations. Suski et al (2012) studied the effects of parental exposure to salinity on hatching success in two gastropod species (Helisoma trivolvis and P. pomila). They found that parental salinity exposure increased the hatching success of H. trivolvis but decreased it for P. pomilia.…”

An important characteristic of epigenetic changes is that they can be produced in response to environmental cues and passed on to later generations, potentially facilitating later genetic adaptation. While our understanding of epigenetic mechanisms in vertebrates is rapidly growing, our knowledge about invertebrates remains lower, or is restricted to model organisms. Mollusks in particular, are a large group of invertebrates, with several species important for ecosystem function, human economy and health. In this review, we attempt to summarize the literature on epigenetic and 4 intergenerational studies in mollusk species, with potential importance for adaptive evolution. Our review highlights that two molecular bearers of epigenetic information, DNA methylation and histone modifications, are key features for development in mollusk species, and both are sensitive to environmental conditions to which developing individuals are exposed. Further, although studies are still scarce, various environmental factors (e.g. predator cues, chemicals, parasites) can induce intergenerational effects on the phenotype (life-history traits, morphology, behaviour) of several mollusk taxa. More work is needed to better understand whether environmentally-induced changes in DNA methylation and histone modifications have phenotypic impacts, whether they can be inherited through generations and their role in intergenerational effects on phenotype. Such work may bring insight into the potential role of epigenetic in adaptation and evolution in mollusks.

“…There is little reliable information on the ecology of Physa pomilia, often confused with Physa acuta as they are morphologically very similar. Recent studies of Suski et al (2012) show that Physa pomilia tolerates increased salinity (4000 μS cm -1 ) but this increase bears (unlike for Physa acuta) no advantage regarding to growth and reproduction. According to Wethington et al (2009), Physa pomilia inhabits pools in backwaters of rivers draining the coastal plain, typically on vegetation.…”

In the Valley of Sobaco located in Coahuila, Mexico, were found the remains of an aquatic ecosystem with a Holocene malacofauna showing similarities to modern aquatic communities of the internationally famous site of Cuatrociénegas, located in the state of Coahuila and known as the "Mexican Galapagos", as it hosts a large number of endemic species. In addition of ostracods, algae, foraminifera, diatoms and remains of vascular plants, the Sobaco paleo-pools (pozas) also contain the gastropods Juturnia coahuilae, Pyrgulopsis manantiali, Coahuilix hubbsi, Coahuilix cf. landyei and Assiminea cienegensis, which are endemic species of Cuatrociénegas Valley. Additional discoveries include sub-recent lacustrine microbial tufas (microbialites, stromatolites), as well a pool that still contains water hosting bacterial communities similar to those from Cuatrociénegas. In this paper we present the taxonomic description of the mollusks from the Sobaco paleo-lake system and a first reconstruction of the paleoenvironment. A comparison of this paleoecosystem with modern aquatic communities of the Cuatrociénegas Valley is also included.
