“…Among the most distinctive elements of malacofauna of South America are the species of the endemic genus Megalobulimus Miller, 1878. This genus includes the largest land snails of the continent, many of which are tied to the rich cultural heritage of South America (Eggers et al 2011;Jaramillo Roldán et al 2014). Megalobulimus are mostly nocturnal snails that have been littlestudied in the wild, including few data on their distributional ranges.…”

Impact of climate change on the distribution of a giant land snail from South America: predicting future trends for setting conservation priorities on native malacofauna

Many land snails are vulnerable to climate change as a consequence of small distribution ranges and poor dispersal. South America is a diverse region in terms of land snail fauna, but studies about the impacts of climate change on molluscan biodiversity are virtually nonexistent. Bioclimatic models provide an important tool to assess how habitat suitability may change in a warming planet. In this study, we examine potential impacts of climate change on a giant land snail (Megalobulimus sanctipauli) from the Atlantic Forest to predict future shifts in its potential distribution, and to identify protected areas that may contain suitable habitat for setting conservation priorities. Using a maximum entropy algorithm, we modeled the species' potential distribution across South America under current climatic conditions and projected the results onto two climate change scenarios for two time frames. A 2.17 % of South America on the Atlantic Forest was predicted to be currently suitable for the species, comprising the border area among Argentina, Brazil and Paraguay. Prognosis of future distribution showed a trend to a northern retraction, but a southern expansion of current potential range. More than 150 protected areas were identified to contain climatically suitable habitat for the species, but on the less optimistic outlook only~1545 km 2 of protected areas (0.009 % of South America) would remain suitable for the species by the end of the century. Our findings are expected to improve understanding of climate change impacts on native giant land snails and to contribute in conservation efforts on this malacofauna.

El caracol nativo Megalobulimus oblongus, también conocido como guácara, caracol criollo o caracol de boca rosada, es una especie de caracol terrestre suramericano, que se encuentra en Colombia, Bolivia, Brasil y Venezuela; alcanza cerca de 100 mm de alto y 60 mm de ancho, con una apertura de borde grueso y rosado; posee cuatro tentáculos en la cabeza y dos grandes barbelos alrededor de la región oral; es de hábitos nocturnos, detritívora y puede vivir hasta 14 años. Desde el punto de vista alimentario, tiene importantes características que lo posicionan como una fuente de gran calidad nutricional que podría ser un buen suplemento alimentario para las personas y los animales; contando adicionalmente con gran potencial para la industria cosmética y artesanal. Sin embargo, hoy en día su existencia está amenazada por la destrucción de su hábitat y la extracción de especímenes de las poblaciones naturales para el comercio ilegal debido a su similitud en tamaño con el caracol gigante africano. El objetivo del presente ensayo es hacer un llamado a la comunidad científica nacional para desarrollar estrategias de conservación y de aprovechamiento sostenible del caracol nativo a través del estudio profundo de su potencial nutricional, cosmético y artesanal.Palabras clave: caracol, conservación de los recursos naturales, especies en peligro de extinción, malacología. A Forgotten Giant: A Call to Protect the Native Snail Megalobulimus oblongus (Mollusca, Strophocheilidae) in ColombiaAbstract. The native snail Megalobulimus oblongus, also known as guácara, criollo snail or caracol de boca rosada (pink-mouth snail), is a South American species of land snail found in Colombia, Bolivia, Brazil and Venezuela. It is about 100 mm high and 60 mm wide with a thick, pink apertural lip, four tentacles on the head, and big flaps on both sides of the oral region. It has nocturnal, detritivorous habits and can live up to 14 years. From a dietary point of view, it has important features that position it as a high quality nutritional source that could be a good food supplement for humans and animals. Additionally, it has great potential for cosmetic and craft industry. However, its existence is currently threatened by habitat destruction and removal of specimens from their natural settlements for illegal trade due to its similarity in size to the giant African snail. The aim of this essay is to appeal to the national scientific community to develop strategies for the conservation and sustainable use of this native snail through a deep study of its nutritional, cosmetic and craft potential.
