Project Data
The collection of Ramazzotti has a scientific value per se, as a collection of slides of a poorly studied group of animals, the phylum Tardigrada, in addition to a historical value. The dataset of the Ramazzotti collection is composed of 3319 tardigrade records, prepared within the Project ITINERIS (Italian Integrated Environmental Research Infrastructures System) dedicated to build the Italian Hub of Research Infrastructures in the environmental scientific domain. The purpose of creating this dataset is to protect the information through the digitalization of the samples, and to facilitate sharing the information on the animals collected by Ramazzotti and stored at CNR-IRSA in Verbania. For this reason, each record in the database is associated with a photograph of the sample in question.

Sampling Methods
As reported on the slide the samples were collected by pumps in an aquatic environment, while for terrestrial ones the sampling methods are unknown. Habitat types for sampling were mosses and lichens in different substrates, soil, water. Different mounting media and colourants were used for the preparation of the slides: mainly Faure and Polyvinyl, but also Formalin, Lactophenol, Carmine Acetic, Chlorazol Black, Eosin methylene, Potassium hydroxide, Turtox CMC-S.
| Study Extent | A total of 4178 records of occurrences for the period 1938-1964 are present in the dataset: 859 refer to slides, 3319 to the actual samples of Tardigrada. Of these, 1751 have a species name, subsumed from the information on the slide, whereas for the others a taxonomic revision is necessary, because the same slide contains more species, and a specialist is needed to attribute each sample to the correct species. However, these individuals have been assigned to a higher taxonomic level such as genus, order or family. Nomenclature of the species was also updated to the currently used synonyms, using WORMS as a reference site (https://www.marinespecies.org). When possible, the coordinates were found by reporting the locations written on the label in Google Earth. Since the specific coordinates of the sampling points are not known, the Locality centroid was used. A total of 204 locations are present in the dataset, but it was possible to trace the coordinates for 88. Data are georeferenced according to WGS 84 datum. |
|---|---|
| Quality Control | Quality control for geographic data: Reliability of coordinates where available was checked in Google maps. Geographic coordinate format, coordinates within country/provincial boundaries, and the absence of anomalous in the dataset were also double checked. Quality control for taxonomic data: The revision of the species nomenclature was done using WORMS as a reference site. Taxon specialists: Giuseppe Ramazzotti, Walter Maucci. |
Method step description:
- The specimens were photographed using a microscope Zeiss Axioplan, with TiEsseLab TrueChrome HD IIS camera and Leica DM6 B, with Leica K3C camera. The size of each photo ranges from approximately 5 MB to 18 MB in BMP and Tiff format. The photos have been renamed to give a unique code for each image, using: CollectionCode, the Roman numeral of the box, the slide number and the number of the specimen. When there is only one animal in a slide, the last number has been omitted. e.g.: RamVB-III-31_4 = box III-slide 31_animal 4. The unique code for each photo is the same as that assigned to the record in the database for the same individual. Photos of slides have been renamed with the Roman numeral of the box, the number of the slide, and the letter S, to indicate that it is the image containing the slide.

| Introduction | The collection has a scientific value per se, being a collection of slides of a poorly studied group of animals, the phylum Tardigrada, in addition to a historical value. The collection was prepared by Giuseppe Ramazzotti (with the exception of 4 slides prepared and identified by Walter Maucci), an Italian amateur taxonomist who lived from 1898 to 1986. In 1962, he proposed the phylum Tardigrada, and in 1968, at the age of sixty, he became a professor at the University of Milan (Bertolani et al., 2011). The Ramazzotti collection is composed of ten boxes, numbered in progressive order with Roman numerals, containing a variable number of slides. There are a total of 855 slides divided as follows: box I contains 100 slides, II 98, III 98, IV 100, V 99, VI 93, VII 85, (VIII is missing), IX 83, X 82 and box XI contains 17 slides. |
| Getting Started | The dataset was developed at CNR-IRSA in Verbania, Italy, and organised in a systematic and coherent way according to Darwin Core Standards (Wieczorek et al., 2012). A total of 4185 records of occurrences for the period 1938-1964 are present in the dataset: 859 refer to slides, 3319 to the actual samples of Tardigrada. Of these, 1778 have a species name, subsumed from the information on the slide, whereas for the others a taxonomic revision is necessary, because the same slide contains more than one species, so a taxonomic expert is needed to attribute each sample to the correct species. However, these individuals have been assigned to a higher taxonomic level such as genus, order or family. Nomenclature of the species was also updated to currently used synonyms, referring to the World Register of Marine Species, WoRMS (https://www.marinespecies.org). We kept all available information for the Collection, thus the dataset with each row containing a record of a tardigrade individual with taxonomy information and images. Dataset includes 4 categories based on the type of information: (i) Basic information regarding the institution to which the collection belongs, with names, acronyms and type of collection. They also refer to the label, including the name of the species and the person who originally performed the determination, as well as the date of first identification, the type of preparation, link to images of the slide and of the animal; (ii) Taxonomy information of the species after taxonomic revision following WoRMS as reference site; (iii) Morphology category about the digitised specimen, with two columns: gender and lifeStage; (iv) Sampling information, such as location, date, who collected the sample and sampling method. |
| Purpose | In the framework of the project ITINERIS, the Ramazzotti collection of Tardigrada, preserved at the Water Research Institute, National Research Council of Italy (CNR- IRSA) in Verbania, Italy, has been the subject of digitization. It is a historical collection that includes samples taken over a period ranging from 1938 to 1964 from different areas of the world. Most of the samples were taken in Europe, in particular from Italy, but also from Germany, France, Finland, Norway, Poland, Austria, Switzerland, Sweden, the Netherlands and the United Kingdom. Other samples are from Africa (Uganda and Congo), North America (United States and Mexico) and South America (Chile). |
| Maintenance Description | Future changes to the dataset due to quality control activities might change its content, however the updates of the dataset are not planned. |
