Description

This dataset comprises 175 records of the freshwater snail Pomacea scalaris (Caenogastropoda: Ampullariidae), gathered from bibliographic sources, human observations, museum specimens and field surveys conducted by the responsible research team.This species is native to Río de la Plata Basin (South America); however, it was accidentally introduced into Southeast Asia along with Pomacea canaliculata and Pomacea maculata. While the latter two species have spread widely and caused significant damage to aquatic crops and  to biodiversity, Pomacea scalaris has not exhibited invasive behavior. The primary purpose of this database is to document both historical and current occurrence records of the species, across its native and introduced range, in order to provide key information for the analysis of distribution partterns, ecological niche modeling, and risk assessment of potential range expansion.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 175 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Geographic Coverage

This resource includes records of Pomacea scalaris from both its native range in South America and its introduced range in Taiwan. In South America, data are concentrated in Argentina, Brazil, Paraguay, and Uruguay. In Taiwan, records are located in various regions of the southwestern and west-central parts of the country. The dataset covers diverse aquatic environments, including both natural and human-modified habitats.

Bounding Coordinates South West [-35.008, -60.753], North East [23.565, 120.602]

Taxonomic Coverage

The resource documents occurrences of the species Pomacea scalaris (d'Orbigny,1835), a freshwater gastropod mollusk of the family Ampullariidae, found in aquatic environments of South America and as an invasive species in Taiwan

Sampling Methods

The records included in this dataset were obtained using multiple strategies. First, collections from the La Plata Museum of Natural Sciences and the Argentine Museum of Natural Sciences were consulted. In addition, georeferenced records were extracted from iNaturalist, selecting observations with appropriate quality grades. For bibliographic data, academic sources were searched using the terms “Pomacea scalaris” and “Ampullaria scalaris,” identifying publications that reported occurrences of the species. Finally, data collected by the resource team during previous field campaigns were included. Records lacking geographic coordinates were georeferenced whenever the site description was sufficiently precise. A visual verification was then performed using QGIS

Study Extent The study area encompasses aquatic regions of South America and East Asia (Taiwan), where the presence of Pomacea scalaris has been recorded. The environments considered include both natural and artificial freshwater bodies such as rivers, lagoons, streams, and canals.
Quality Control Records without verifiable geographic coordinates were discarded. Additionally, works authored by the same individuals, in which specimens were collected from the same locality, were excluded to avoid duplication of the same specimen. iNaturalist records were manually reviewed and filtered based on validation level. Furthermore, iNaturalist records with photos in which the species could not be clearly identified were excluded, as well as records from locations where the species could be easily confused with others.

Method step description:

  1. 1. Request and data collection from museums and biological collections. 2. Review of historical records from previous samplings conducted by the team. 3. Search and download of relevant observations from iNaturalist, excluding those lacking photos that allowed clear species identification or originating from areas where the species could be confused with others. 4. Review and data extraction from scientific literature. 5. Georeferencing and visual verification using QGIS of records that did not originally include geographic coordinates. 6. Data standardization according to the Darwin Core schema. 7. Taxonomic and geographic validation. 8. Final integration and curation of the dataset.
