Land and freshwater molluscs of Northern Spain
“Land and freshwater molluscs of Northern Spain” is an occurrence dataset containing 222 observations of 73 different taxa of land and freshwater molluscs encountered in Northern Spain (Vízcaya, Cantabria and Asturias). Various sites were inspected in a period between 2004 to 2019. The aim is to contribute to the knowledge on the ecology and distribution of these species such that it may aid conservation and research of these organisms in the future. The dataset is published as a standardized Darwin Core Archive and includes for each observation a stable occurrenceID, scientific name, date, and location of the observation, as well as info on lifeStage and organismQuantity, and supplementary remarks on the determination and the observation itself. We have released this dataset to the public domain under a CC0 1.0 Universal (CC0 1.0) Public Domain Dedication (https://creativecommons.org/publicdomain/zero/1.0/).
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 222 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.

Land and freshwater molluscs do not comprise a monophyletic taxonomic group, but are all mollusc species that live in respectively land and freshwater habitats. On land, only gastropods occur (class Gastropoda, snails and slugs) and in freshwater, both gastropods as bivalves (class Bivalvia) occur.
|Start Date / End Date||2004-08-18 / 2019-09-16|
Sampling was done ad random along random routes. Collection of specimens was mainly done by hand on sight. In some cases, a soil sample was taken that was later examined at home.
|Study Extent||Locations were not predefined, but some regions were specifically visited because of known species richness or endemics occurrence. At site, observations were incidental, but microhabitats or elements that were thought to be favourable for snails or were given more attention (e.g. dead wood, north facing slopes etc.).|
|Quality Control||Multiple different sources were consulted for determination of the species. The dataset was reviewed by Han Raven (an expert on land and freshwater molluscs of Northern Spain) before publishing. His remarks and tips were used for improvement of the dataset.|
Method step description:
- Determination was mainly done with Cadevall & Orozco (2016) and Welter-Schultes (2012) and for species with a wider, European, distribution also the following works were consulted: Cameron (2008), Glöer (2015), Horsák (2013), Jansen (2015). Finally, the following articles were consulted as well: Arconada et al. (2007) and Rolán et al. (2009) for Alzoniella, Gittenberger & Bank (1996) for Pyramidula, Gittenberger (1973) for Chondrina, Raven (1990) for Obscurella, Suárez & Quiñonero Salgado (2017) for Plentuisa vendia, Prieto et al. (2020) for Oestophora, Suárez et al. (2019), Elejalde et al. (2009) and Caro et al. (2019) for Pyrenaearia (see also Langeraert, 2017), and De Winter (1986) for Arion urbiae.
