“…Although interest has been expressed in controlling the spread of non-native apple snails in Florida, we have to recognize that the scale of the invasion, now throughout Florida in wetlands, lakes, canals, ponds, and rivers [29], will likely preclude eradication. Hand removal of snails and eggs may be effective at a small scale [75], but likely not plausible, and too costly, to be effective in systems the size of LTOHO and WCA3A. Other snail removal methods, such as introducing predators or application of molluscides, would target native as well as non-native snails, and potentially harm other species [75,76].…”

Contrasting Patterns of Pomacea maculata Establishment and Dispersal in an Everglades Wetland Unit and a Central Florida Lake

The spread of non-native species raises concerns about native species displacement, while other negative effects on native species (e.g., habitat degradation) should also be considered. The highly invasive non-native apple snail Pomacea maculata has raised such concerns as it has become established in a wide range of aquatic systems worldwide. While monitoring native Florida P. paludosa populations in Lake Tohopekaliga (LTOHO) from 2001 to 2009 and in Water Conservation Area 3A (WCA3A, Everglades) from 2006 to 2015, we opportunistically documented the establishment and distribution of P. maculata. We estimated snail densities and recorded egg cluster presence in three study sites (12 total plots, LTOHO) and 137 sites (WCA3). On LTOHO, native snails were absent or at very low densities prior to finding P. maculata. Few snails of either species were found in high-stem-density vegetation of the littoral zone. Pomacea maculata immigration into the littoral zone occurred following managed vegetation removal, and Hydrilla verticillata proliferation in LTOHO likely contributed to the spread of P. maculata. We found both native and non-native apple snail species in many WCA3A sites following P. maculata invasion. We initially found the non-native snail in two sites in southern WCA3A; they were mostly restricted to within three kilometers of initial sites over the next four years. Overall plant community compositions in LTOHO and WCA3A appeared less impacted than expected based on previous reports of P. maculata invasions.

Complete removal is not necessary as a small population in the long term is likely to be extirpated as long as they are not "rescued" genetically by migration.…”

Aquatic Invasive Species (AIS) are a significant threat to global freshwater biodiversity. This study focuses on the banded mystery snail, Callinina georgiana, an invasive species in the Adirondack region of northern New York, an important section of the New York Great Lakes Basin. This project aims to explore the genetic connectivity of C. georgiana within its invasive range using a combination of mitochondrial and nuclear markers. Sampling was conducted in the Raquette River and adjacent waterways, with a total of 229 snails collected from 16 distinct populations distributed across eight different waterbodies. Also included were two populations from the species native range in the southern United States. DNA was extracted, and a 710 bp fragment of the mtDNA marker COI and a 351 bp fragment of nuclear marker Histone3 (H3) were amplified. Population genetic analyses including haplotype patterning, AMOVA and genetic diversity estimates, neutrality tests and tests for isolation by distance (IBD) were performed to assess connectivity patterns. Results showed moderate to high levels of genetic admixture within the invasive range as indicated by the lack of geographic patterning of haplotypes and low to moderate levels of genetic differentiation across multiple sites. Demographic analyses combined with high numbers of private haplotypes indicate population expansion. Interestingly, a case of mitonuclear discordance was detected for native and invasive populations as evident by incongruent haplotype patterns for the COI and H3 markers. Callinina georgiana exhibits a high level of genetic connectivity in its invasive range. The presence of dams does not significantly affect gene flow, indicating that anthropogenic activities, such as boat traffic might be key in dispersing the snails across this fragmented freshwater system. This study offers new insights into the dispersal and genetic structure of an invasive freshwater snail. It highlights the importance of considering anthropogenic factors when confronting complex patterns of genetic diversity. The findings are significant for biodiversity conservation and provide a basis for developing strategies to manage and contain the spread of AIS like C. georgiana, especially in regions with high human activity.

“…Because of their conspicuous and generally accessible egg masses, hand-picking eggs (and matured adults when they are active in the morning and evening) can also prove effective as an early intervention method (Bernatis and Warren, 2014). Furthermore, by placing bamboo stakes around the fields to provide places for snails to lay eggs, this can facilitate collection/destruction of eggs (Jahn et al, 1997).…”
