“…Even the north central area could be identifi ed as susceptible, although with a low probability. Nonetheless, it is important to maintain vigilance of this area because it is comprised of Subtropical Cloudforest (Yungas), which shares some environmental conditions with the Paranaense Rainforest (located in northeastern Argentina, southern Brazil, and East of Paraguay), where the species is already present (Miranda andCuezzo 2010, Gutiérrez Gregoric et al 2011).…”

The best way to reduce problems related to invasive species is by preventing introductions into potentially susceptible areas. The purpose of this study was to create distribution models for the invasive gastropod Achatina fulica Bowdich, 1822 in South America in order to evaluate its potential geographic distribution and identify areas at potential risk. This mollusc, considered one of the 100 world's worst invasive alien species, is the focus of intense concern due to its impact on agriculture, human health, and native fauna. We tested two commonly used ecological niche modeling methods: Genetic Algorithm for Rule-Set Prediction (GARP) and Maximum Entropy (MaxEnt). Models were run with occurrence points obtained from several sources, including the scientifi c literature, international databases, governmental reports and newspapers, WorldClim bioclimatic variables, and altitude. Models were evaluated with the threshold-independent Receiver Operating Characteristic (ROC) and Area Under the Curve (AUC). Both models had consistent performances with similar areas predicted as susceptible, including areas already affected and new potentially susceptible areas in both tropical and temperate regions of South America.

“…Extensive fieldwork was conducted over the last 20 years in different ecoregions, with sampling efforts standardized over time. Collecting methodology and laboratory procedures followed Cuezzo (1997, 2006), Salas Oroño et al (2007), Miranda and Cuezzo (2010, 2014), and Gutiérrez Gregoric et al (2013). Thus, geographical coordinates were mainly compiled from this fieldwork.…”

Twenty-five sub-ecoregions make Argentina from southern South America a favored area to study the mutual correspondence between environments and biodiversity. Unfortunately, efforts devoted to study these environments are unbalanced, with the subtropical dry forests less studied than the tropical and subtropical humid ones. Since the limits of ecoregions are based on vegetation criteria, land gastropods represent an independent source of information to test the relevance of sub-ecoregions in different aspects of biodiversity. We ask if land gastropods mirror these traditional diversity patterns when their distributions are framed in the context of sub-ecoregions. Additionally, we want to test if short-range endemic species (SRE) are randomly scattered across the sub-ecoregions. We first built an updated taxonomic checklist and mapped all the valid records compiled to date. Taxonomic richness, taxonomic diversity, and beta-diversity between sub-ecoregions were calculated. We obtained a hierarchical grouping of sub-ecoregions and the respective list of species that significantly support each cluster. We also developed two new analytical resources: a radial plot for showing the species composition of clusters resolved at three taxonomic levels, and a mixed coefficient of distributional size useful to identify SRE from sparse point records. This dimensionless measure of spatial range combines information of both the convex hull area and the length of the minimum spanning tree connecting point localities of presence. The Southern Andean Yungas and Dry Chaco are the species-level richest ecoregions. Although the Paranaense Forest harbors half of the number of species found in the Chaco Serrano, it reaches the highest score of taxonomic diversity because of the eclectic nature of their genera. SRE species are not randomly distributed across the sub-ecoregions, but they broadly overlap with the orographic Peripampasic arc extended over Chaco Serrano and Yungas Forests. SREs are highly dependent on the physical nature of the landscape.

“…Con respecto a otras áreas de la Argentina, es poco lo que se conoce acerca de la diversidad de moluscos terrestres, a excepción de los estudios realizados en la provincia de Tucumán (Salas-Oroño et al, 2007, Miranda & Cuezzo, 2010. En esta última, y particularmente en el área de las Sierras de San Javier se registran 13 familias, 21 géneros y 32 especies de gasterópodos terrestres (Miranda & Cuezzo, 2010). Estos valores son similares a los registrados en la UM con mayor riqueza de Misiones (D1), con 16 familias, 27 géneros y 35 especies.…”

“…Es de destacar que la totalidad de las familias referidas para las Sierras de San Javier (a excepción de xanthonychidae) se encuentran en la provincia de Misiones. Sin embargo, el número de micromoluscos hallados en la provincia de Tucumán fue relativamente mayor al registrado en la provincia de Misiones (31 vs. 25;Salas-Oroño et al, 2007, Miranda & Cuezzo, 2010, debido probablemente a la realización de estudios más intensivos en este tipo de malacofauna en Tucumán.…”

“…Los estudios referidos a la riqueza y diversidad de moluscos terrestres en selvas tropicales y subtropicales son escasos, sin embargo, los pocos que se han realizado han demostrado que la malacofauna terrestre en dichos ambientes puede presentar alta riqueza específica, así como elevada diversidad (Salas-Oroño, Cuezzo & Romero, 2007). Entre los estudios previos realizados en Sudamérica se pueden mencionar los realizados por Gargominy & Ripken (1998) en Guyana Francesa, Miquel et al (2007a) en Brasil, Ramírez et al (2012) en Perú, y Salas--Oroño et al (2007) y Miranda & Cuezzo (2010) en la Argentina. Estos dos últimos trabajos realizados en la Selva Nublada (Yungas) de la provincia de Tucumán.…”

Terrestrial gastropods from Misiones Province, Argentina. The Atlantic Forest represents one of the global priority eco-regions for biodiversity conservation. In Argentina, this is represented by the Paranense Forest, which occupies much of the Misiones Province. In this paper, an updated list of land mollusks from Misiones Province is presented, and its species richness was evaluated comparing protected and unprotected areas. For this, we reviewed La Plata Museum Mollusk Collection, updated the literature review, and developed some field work between 2009 and 2010. For the areographic work, a grid (50x50km) was applied to a Misiones province map. In this region, large areas of native vegetation constituting the Paranaense Forest still persist, and include protected areas such as the Iguazú National Park and Puerto Península Provincial Park. These areas have been the most explored at the malacological level (both terrestrial and aquatic environments), a fact that is consistent with the greater number of records found, which may also be the explanation for the highest number of species recorded in the region. A database containing 497 records was compiled. The number of species occurring in this Province was increased from 28 to 56; 11 of which were exotic species. A total of 38 of the species occurred in protected areas and 53 in unprotected areas; and 25 species were micro-mollusks. Orthalicidae was the family with the highest species number (10) and the widest distribution, occupying 16/20 sampling units. Megalobulimus was the genus found in a greater number of sampling units (14/20). The highest values of specific richness of land gastropods were found in Northern Misiones (R=32). This richness was similar to that previously reported for the Tucumán Province, although species occurring in both provinces were mostly different. The richness in Misiones Province border areas, as the Republic of Paraguay and the state of Santa Catarina (Brazil), was about twice that found in the province. The present study showed the existence of poorly explored areas at malacological level, especially in Central and Eastern Misiones. Data presented here will allow focus future sampling efforts on such areas, so patterns of species distribution can be better defined.
