“…La introducción de A. fulica en el continente americano se ubica en Hawái hacia 1939, llegando a Norteamérica (California) al final de la segunda Guerra Mundial, se registró en la Florida a comienzos de la década de los años 70´s (GODAN,1983). Se plantea que la introducción de A. fulica en Suramérica se inició por Brasil hace unos 22 años, se le relaciona con procesos de helicicultura (SANTANA-TELES et al, 1997;AQUINO, 2010).…”

El presente trabajo muestra la colonización de Acathina fulica en Sincelejo, al tiempo que reporta la ocurrencia de esta especie exótica invasora en Sampués, Sucre, Colombia. Mediante entrevista a los pobladores de los distintos barrios de ambas ciudades se reconoció la presencia del caracol africano gigante, posteriores muestreos permitieron la captura de ejemplares que confirmaban su presencia. La densidad calculada estuvo entre 0,0031 y 0,0044 ind/m2, la cual es relativamente baja al compararla con registros preestablecidos para otros países. La talla de los ejemplares medida como la longitud en línea recta de la concha, no presentó diferencias significativas entre las áreas de muestreo y se registra inferior a lo establecido como talla máxima para la especie. Los datos obtenidos en este estudio muestran un incremento de la dispersión de A. fulica en el territorio del departamento de Sucre, que si bien es incipiente y aún no representa un peligro inminente, debe atenderse con el debido cuidado, dadas las posibles devastaciones que como plaga posee esta especie a nivel ambiental y agrícola.

“…Comparing to the data obtained by Caetano (2005) and Ohbayashi & Takeuchi (2007), the weight and height average shell were lower than those obtained by this, as compared to Albuquerque (2003) the average obtained were higher. The specimen large and strong presence, probably with sexual development complete reflects the process of invasion of the species in Salvador, with the occupation of urban ecosystems, not only causing serious ecological and economical problems, but also possible damages to human and domestic animals health (Teles et al 1997, Vasconcellos & Pile 2001, Raut & Barker 2002, Bender et al 2003, Thiengo et al 2006, Thiengo et al 2007, Thiengo et al 2008.…”

“…Known as giant African snail, the land pulmonate mollusc Achatina fulica Bowdich, 1822, reaches considerable dimensions, nearly 20 cm shell length and weigh up 200 g (Teles et al 1997, Vasconcellos & Pile 2001, but in Brazil the maximum average records vary in about 11 cm and little over 100 g (Vasconcellos & Pile 2001, Carvalho et al 2003, Simião & Fischer 2004, Fischer & Colley 2005, Fischer et al 2006). …”

Abstract:The risks following introduction of invasive species are enormous and incalculable. Achatina fulica is considered one of the 100 species of greatest invasive potential, stands out among the land pulmonate snails, mostly for its high reproductive potential that accelerates the process of dispersion, increasing the damages related to health (disease transmission), to economy (crops destruction) and to environment (biodiversity loss). In order to investigate the relationship of the African snail with the environment, trying to relate sexual activity with climatic variables (temperature, rainfall and humidity), a study was conducted on aspects of population dynamics and reproductive biology in Salvador city. The snails were collected by hand, monthly. Morphometric data were obtained in the field and dissections to analyze the reproductive system at laboratory. To test if there was a greater sexual activity in wet periods was performed first a Principal Component Analysis (PCA) with climatic variables, followed by a regression between precipitation (the most influential environmental variable) and the variable of interest (sexual activity). The results showed that there is an apparent annual cycle for A. fulica, with a recruitment period covering the end of rainy season and the dry season (August to December 2006 and February 2007). Increase of shell size (height) and of sexual activity were observed during the rainy season, although snails were found in full sexual activity during the whole period of study. The von Bertalanffy curve showed that the oldest specimen collected would have three years and eleven months. The regression between precipitation and sexual activity was significant (P = 0.002) showing that the higher rainfall increased sexual activity. In addition, it was observed that there is an increase in the thickness of peristome as the specimens reaches sexual maturity however this relationship isn't precise (it were found individuals with sexual structures not consistent with the reproductive stage given by the thickness of peristome) and should be set for each region studied. As the eradication becomes impossible because of high level of invasion found in Salvador, it is recommended to control the population of African snails by continuously removing specimens, especially in the rainy periods.

“…The Giant African Snail, Lissachatina fulica (Bowdich, 1822), is considered one of the world's most invasive species, with considerable known negative impacts. This species is native to East Africa [15], and it was introduced in South America in the 1980s as a substitute for the escargot Cornu aspersum (Müller, 1774) as a human food item [16]. Since then, the species has rapidly spread across the continent, possibly still currently invading some areas [17][18][19].…”

How Will the Distributions of Native and Invasive Species Be Affected by Climate Change? Insights from Giant South American Land Snails

et al. 2022

Climate change and invasive species are critical factors affecting native land snail diversity. In South America, the introduced Giant African Snail (Lissachatina fulica) has spread significantly in recent decades into the habitat of the threatened native giant snails of the genus Megalobulimus. We applied species distribution modeling (SDM), using the maximum entropy method (Maxent) and environmental niche analysis, to understand the ecological relationships between these species in a climate change scenario. We compiled a dataset of occurrences of L. fulica and 10 Megalobulimus species in South America and predicted the distribution of the species in current and future scenarios (2040–2060). We found that L. fulica has a broader environmental niche and potential distribution than the South American Megalobulimus species. The distribution of six Megalobulimus species will have their suitable areas decreased, whereas the distribution of the invasive species L. fulica will not change significantly in the near future. A correlation between the spread of L. fulica and the decline of native Megalobulimus species in South America was found due to habitat alteration from climate change, but this relationship does not seem to be related to a robust competitive interaction between the invasive and native species.
