“…At the fourth week, all nine P. canaliculata initially added to the paddy systems were recovered from the PNEC treatments (i.e., 100% survival rate), but none were recovered from the two HC 50 treatments (i.e., 0% survival rate), regardless of the type of acid ( Table 1 ). The pH tolerance of snail species belonging to the same class (Gastropoda) as P. canaliculata , has been reported to be between 5.5 and 9.5 [ 20 ]. The extreme acidity (e.g., pH < 3.8 during the first to fourth week; Figure 1 a) developed in the HC 50 treatments seems detrimental to P. canaliculata , leading to high fatality.…”

Paddy mesocosms comprising of rice (Oryza sativa), snail (Pomacea canaliculata), and worm (Tubifex tubifex) were used to assess the damage caused by two acids (HNO3 and H2SO4) at predicted no-effect concentration (PNEC) and hazardous concentration for 50% of species (HC50) levels. In the fourth week, the fresh weight and shoot height of O. sativa at H2SO4-HC50 were reduced by 83.2% and 30.3%, respectively. Wilted leaves (%) at HC50 were approximately twice that at PNEC. No P. canaliculata and T. tubifex were recovered at HC50. At H2SO4-PNEC, the length and weight of P. canaliculata were reduced by 7.4% and 25.9%, respectively, whereas fewer adult (46.5%) and juvenile (84%) T. tubifex were recovered. In the 20th week, rice growth and productivity were correlated with initial pH (pHi) and nitrogen levels. Poor correlation with chlorophyll at the active tillering stage suggests the disturbance of nutrient uptake by roots. Partial least squares path modeling (PLS-PM) results further supported that the pHi directly affects grain yield and quality, as well as plant growth. The indirect effect via intervening fourth-week-variables was also substantial. Therefore, it is important to measure initial pH upon acid spill to estimate the risk to the paddy ecosystem. Information on the change in soil properties associated with acidity will also aid in predicting the yield and quality of grain to be harvested.

“…1) possible genetic exchange, genetic bottlenecks and genetic drift (Matsukura et al 2013;Shirk et al 2014), which could be the result of the initial founder event that led to speciation in P. canaliculata and P. maculata (Freeland et al 2011); 2) the introduction of alien species to a non-native location may not be directly from the native range, but from a successful invasive population elsewhere, which could be the result of the bridge-head effect (Eric et al 2010); 3) sample numbers of Pomacea for each country were significantly different for this study, so further genetic analysis is needed to clarify this (Hayes et al 2008); 4) growth and reproduction of P. canaliculata and P. maculata are closely related to water temperature: many studies showed that the snail was not adapted to low temperatures (Andree and López 2013;Byers et al 2013;Hayes et al 2015;Bernatis et al 2016). In addition, climate change (Byers et al 2013) and environment factors such as pH (Byers et al 2013), calcium carbonate (White et al 2007;Perlman 2016), dissolved oxygen (Seuffert and Martín 2009), salinity (Verbrugge et al 2012;Martin and Valentine 2014) may affect their life history.…”

Phylogeographic patterns and demographic history of Pomacea canaliculata and Pomacea maculata from different countries (Ampullariidae, Gastropoda, Mollusca)

Invasive species of Pomacea snails are of growing concern when it comes to the conservation of global biodiversity. Pomacea canaliculata has been listed among the world’s 100 worst invasive species. In this work, phylogeographic patterns and the demographic history of P. canaliculata and P. maculata from different countries were analyzed using mtDNA cytochrome c oxidase subunit-I (COI) sequences. The results showed that P. canaliculata and P. maculata had high genetic diversity, significant genetic differentiation, limited gene flow and stable population dynamics among different countries. Genetic diversity of P. canaliculata was higher than P. maculata. Our study will also provide important information for the effective prevention and control of the spread of Pomacea snails.

“…Under unfavourable conditions and in some deep‐water rice, salinity increases in the dry season due to saltwater intrusion in river channels and from saline water rising by capillary action (Catling,). Few studies have examined the effects of salinity on apple snails; however, adult P. canaliculata and P. maculata are capable of tolerating salinities ranging from 3‰–8‰ (Ramakrishnan, ; Bernatis et al ., ). Apple snails will not survive in estuarine and salt‐water conditions, although the eggs of P. maculata can survive short term exposure to salinities above 10‰ (Martin & Valentine, ).…”

“…This will also allow any surviving snails to grow and reproduce, and to recolonise newly flooded rice fields. The pH of water at which adult and juvenile P. canaliculata and P. maculata can survive without appreciable mortality (above 40%) is between 5.5 and 9.5 (Bernatis et al ., ). As with salinity, paddy water is normally within this range (DeDatta, ).…”

The ecophysiology of apple snails in rice: implications for crop management and policy

This review relates the ecology and physiology of apple snails (Ampullariidae) to their impact on rice-production systems. Two species in particular, Pomacea canaliculata and Pomacea maculata, have been introduced to several rice-growing regions. Flooded rice systems represent a high-quality habitat for these apple snails because of similarities in the environmental conditions (water temperature, salinity, pH, water flow velocity) necessary for both rice production and for snail survival and development. Furthermore, amphibious respiration, a capacity to aestivate during dry periods, as well as cold acclimation and tolerance (particularly in P. canaliculata), increases the resilience of apple snails to rice farming practices, including agrochemical applications, intermittent drainage and crop rotations -under a wide range of climatic conditions. Risks to regional rice production depend on four principal factors: these are (a) regional climate, (b) regional rice-production systems, (c) prevailing production practices, and (4) the presence/absence of invasive, non-native apple snails. Based on these criteria, lowland irrigated rice in tropical and subtropical regions that is wet-direct seeded is most vulnerable to damage from both native and non-native apple snails (albeit with greater losses from non-native snails because of normally higher densities). Adequate quarantine regulations, particularly in vulnerable tropical regions that are adjacent to centres of recent outbreaks (e.g. India and Bangladesh adjacent to Myanmar, Peru and Colombia adjacent to Ecuador) and attention to the preparedness of farming systems could reduce potential impacts as these highly invasive snails continue to spread. The urgent development of labour-saving crop-establishment methods that reduce dependencies on chemical molluscicides is necessary to achieve sustainable rice production in regions at risk from non-native apple snails.
