... Pomacea canaliculata is expanding worldwide (Yang et al. 2022;Yin et al. 2022). One possible factor contributing to the recent expansion of the distribution range is climate warming (Lei et al. 2017;Hah et al. 2022), although other factors such as water quality and moisture may also be important in determining its distribution (Ito 2002;Qin et al. 2023). Pomacea canaliculata often fails to overwinter in temperate regions (Wada and Matsukura 2007;Yoshida et al. 2009). ...

Pomacea canaliculata , a freshwater snail native to South America, has become widely naturalised in many countries, causing serious damage to agricultural and native ecosystems. Although climate warming is likely to expand the distribution of this species, limited information exists regarding its impact on feeding activities. In this study, we examined the effects of temperature on the feeding activity of this species and estimated the impact of climate warming on its feeding potential. The feeding activity was determined by measuring the amount of standard food (Japanese mustard spinach, komatsuna) ingested at different temperatures. It tended to increase from 15 to 25 °C but became almost stable from 25 to 35 °C. The respiration rate determined by the O 2 consumption rate, showed a similar response to temperature. Based on these findings, we constructed a simple model to estimate the relative feeding activity using climatic data recorded at meteorological stations throughout the Japanese Archipelago. The model estimated that, with warming of + 2 °C, annual feeding potential (relative value) increased by 21.1% at the present northern distribution limit of this species. The effect of warming on percentage increase in feeding potential was estimated to be smaller at the southern distribution limit (9.9%), although the absolute feeding potential was larger than that at the northern sites. The model also suggested that if this species expanded its northern distribution range as a result of climate warming, it would have a high feeding potential comparable to that of the southern regions.
... Environmental variables Bio1 and Bio18 have the highest weight, influencing the water and heat requirements crucial for the northward expansion of P. canaliculata. These findings are consistent with the research of Lv (2011) [64], Yang (2022) [26], Yin (2023) [47], Seuffert (2021Seuffert ( , 2024 [28,29], and Qin (2023) [65], all highlighting the primary environmental variables-water and heat-as influencers of the suitable habitat for P. canaliculata. P. canaliculata predominantly thrives in warm and humid environments, while dry conditions and cold winters act as limiting factors for its range expansion. ...

Pomacea canaliculata is widely distributed in the Chinese provinces south of the Yangtze River, causing serious damage to aquatic ecosystems, rice cultivation, and human health. Predicting the potential geographic distributions (PGDs) of P. canaliculata under current and future climate conditions in China is crucial for developing effective early warning measures and facilitating long-term monitoring. In this study, we screened various species distribution models (SDMs), including CTA, GBM, GAM, RF, and XGBOOST, to construct an ensemble model (EM) and then predict suitable habitats for P. canaliculata under current and future climate scenarios (SSP1-26, SSP2-45, SSP3-70, SSP5-85). The EM (AUC = 0.99, TSS = 0.96) yielded predictions that were more precise than those from the individual models. The Annual Mean Temperature (Bio1) and Precipitation of the Warmest Quarter (Bio18) are the most significant environmental variables affecting the PGDs of P. canaliculata. Under current climate conditions, the highly suitable habitats for P. canaliculata are primarily located south of the Yangtze River, collectively accounting for 17.66% of the nation’s total area. Unsuitable habitats predominate in higher-latitude regions, collectively covering 66.79% of China’s total land area. In future climate scenarios, the total number of suitable habitats for P. canaliculata is projected to expand into higher latitude regions, especially under SSP3-70 and SSP5-85 climate conditions. The 4.1 °C contour of Bio1 and the 366 mm contour of Bio18 determine the northernmost geographical distribution of P. canaliculata. Climate change is likely to increase the risk of P. canaliculata expanding into higher latitudes.
... They also reported a niche expansion of 83% between native and invaded areas, a little higher than our values of 65% and 75% for "Asia" and "America," respectively, but this is probably also explained by the limited native range used. In other recent study analyzing niche shift of P. canaliculata between its native range and the invaded range in USA and China, Qin et al. (2023) also found shifts toward higher annual precipitation and lower minimum temperatures in China. In our results, the minimum temperature also showed a great expansion from the native to the invaded range in "Asia," but we found a shift to both lower and higher values of this variable. ...
... This could be related to the fact that we considered all the invaded regions in Asia, and not only China, which includes more diverse temperatures. Qin et al. (2023) also reported a broader range of precipitation conditions in the invasive niche of P. canaliculata in the USA. They found lower niche expansions relative to our results (24% in China and 39% in the USA), but this could also be explained by the fact that our invaded ranges are more complete and include regions with very different climatic conditions. ...

Biological invasions represent one of the major threats to biodiversity. The apple snail Pomacea canaliculata is a South American freshwater snail that was introduced in many regions around the world, becoming a successful invader. In this work, we provide an updated and accurate database of P. canaliculata records worldwide, test the realized niche shift between native and invaded regions, and perform current and future ecological niche models. Records were retrieved from sampling data, scientific literature, biodiversity databases, and communication with researchers with expertise in apple snails. The niche of P. canaliculata substantially changed between its native range and its invaded ranges in Asia and the rest of Amer-ica. Current and future suitability were modeled, considering both native and invaded records, to reflect all environmental conditions where snails' populations can establish. Many temperate, subtropical, and tropical regions around the world are currently suitable, many are already inhabited, and others not colonized yet. Niche models predict that in the next 80 years, suitable areas would retract more than they expand on a global scale, with the worst scenario of climate change promoting the greatest changes. Most of the predicted changes would be the retraction in South America, Africa, and Australia and the expansion toward higher latitudes, especially to northern Patagonia, northern USA, and central Europe. Niche shifts can be the result of limitations in dispersal, changes in biotic interactions, or adaptation to new climatic environments. Standardized evaluations across native and invaded ranges are needed to understand the role of contemporary evolution in the niche expansion and life history changes of P. canaliculata and its invasion success.

In recent years, Pomacea canaliculata has aggressively invaded rice fields in Asia, resulting in significant agricultural losses. Biological control can effectively reduce the damage caused by P.canaliculata. This research evaluates E. sinensis as a biocontrol for P. canaliculata, focusing on its feeding preferences and optimal control density on snails of three sizes, as well as the effects on the nutritional quality of juvenile crabs post consumption. Our findings reveal that juvenile E. sinensis exhibit a strong preference for feeding on small snails, effectively managing populations at densities of 600 snails per tank. Crab feeding significantly reduces the survival and activity of snails. Furthermore, consumption of P. canaliculata meat alters the crabs’ physiology. Female crabs show elevated levels of molting hormones, total energy yield (TEY), and condition factor (CF), while males demonstrate increased lipid, moisture, and TEY levels. The amino acid profiles shift, with higher isoleucine and leucine levels in female hepatopancreas and reduced histidine in the muscles. Notably, the total Σn-3 PUFA content in female muscles fed on snail meat exceeds that of those given commodity grain. This study underscores the dual benefits of employing juvenile E. sinensis for managing P. canaliculata while enhancing crab farming practices.

The invasive golden apple snail Pomacea canaliculata is one of the devastating threats to aquatic ecosystems and wetland agriculture worldwide. Macrolides from microbes display various advantages over other compounds in controlling snails. However, emergence of antibiotic-resistant phenotypes against certain macrolides in the field appeals for exploring more effectively molluscicidal macrolides. Here, two borrelidins, borrelidin BN1 and BN2, from the extract of a Streptomyces strain fermentation were evaluated for molluscicidal potential against P. canaliculata using both immersion and contact bioassay methods. Borrelidin BN1 (borrelidin A) presented a significant molluscicidal activity comparable to the chemical pesticide metaldehyde, and had a much lower median lethal concentration value (LC50, 522.984 μg·ml-1) than avermectin B1 at 72 h of contact-killing treatment. Snail growth was inhibited by borrelidin BN1 more than by metaldehyde at sublethal concentrations, consistent with responses of key biochemical parameters. Exposure to borrelidin BN1 decreased the activity of acetylcholinesterase (AChE), glutathione S-transferase (GST), aspartate aminotransferase (AST), alanine aminotransferase (ALT) as well as the levels of energy reserves and sex steroids in snail tissues, while increased the activity of superoxide dismutase (SOD), catalase (CAT), lactate dehydrogenase (LDH) and the level of lipid peroxidation (LPO). Further application assay confirmed that borrelidin BN1 protected crop plant Zizania latifolia from P. canaliculata damage via suppressing snail population density. These findings suggest great potential of borrelidin BN1 as a molluscicide. Additionally, its higher activity than the stereoisomeric borrelidin BN2 (borrelidin F) implied better molluscicidal borrelidins could be acquired through structural optimization.
