A new program dedicated to cataloguing and digitizing the Ruggieri Ostracod Collection has been launched in collaboration with the ‘Istituto Centrale per il Catalogo e la Documentazione’ (ICCD), of the Italian Ministry of Culture.

Additional outreach efforts include showcasing ostracods through the museum’s social media channels and via the multimedia totem on the first floor, which illustrates the Messinian Mediterranean desiccation and the Lago Mare Fauna, both subjects extensively studied by Ruggieri itself. Together, these actions aim to improve public engagement with microfossil collections while supporting their use by visitors and specialists alike.</div><div>The aim of this work is to document the scientific relevance of the Ruggieri Ostracod Collection, to describe the procedures used for its digitization within the SIGECweb framework, and to present recent strategies implemented to enhance its visibility and accessibility to both specialists and the general public.

The present condition report of the collection was performed through a detailed inventory of 885 slides and highlighted the mounting techniques used by Deflandre (medium, sealant, dyes). First, the recipes were documented using the available literature. Then, an inventory was undertaken using a spreadsheet with pre-defined entries, designed to facilitate analysis of collected data. Well-documented labels and some chemical analyses were used to fill in the fields. More than 50 combinations of dyes, 19 mounting media and three sealants were used. Regarding the media condition, attention was focused on three major points affecting the observation of the specimens and the long-term conservation of the slides: the color, the mechanical degradation, and the presence of air. Most widespread media in Deflandre’s collection are Canada balsam, coumarone resin and kumadax, all exhibiting yellow or orange tints due to oxidation, but not impacting the condition of specimens. Glycerin jelly was the least stable mounting media with evidence of darkening and shrinking. In general, no relationship between yellowing and mechanical degradation was noticed, nor was a link between the macroscopic sealant degradation and the drying of the mounting medium. Cross-referencing information between the literature and the collection allowed a better understanding of the mounting practices. Additionally, observing these 50–100 year old slides was one of the best ways to assess the durability of mounting media through time.</div></div>","PeriodicalId":45442,"journal":{"name":"REVUE DE MICROPALEONTOLOGIE","volume":"90 ","pages":"Article 100881"},"PeriodicalIF":1.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145840488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses this gap by conducting a multi-proxy analysis and direct comparison of two tufa-depositing systems in Thuringia, Germany: the modern Pennickental stream and an early Holocene profile from Plinz. By integrating ostracod, mollusc, plant macrofossil, and sedimentological data within the established palynological and isotopic framework for the Plinz site, we reconstruct a three-stage hydrological succession. The record begins with a cool, stable, spring-fed stream during the post-glacial transition (Zone A), transitions to a shallow, standing-water pond during the climatic amelioration of the early Holocene (Zone B), and ends in a cool, groundwater-dominated mire following a late Preboreal/early Boreal cooling event. In contrast, multivariate analysis of the modern Pennickental system reveals a spatially heterogeneous community structured by contemporary hydrochemical and hydrodynamic gradients. This comparative framework allows for the decoupling of two fundamental modes of biodiversity organization: the high temporal beta diversity at Plinz, driven by long-term ecological succession and faunal turnover in response to major climatic forcing, versus the high spatial beta diversity at Pennickental, maintained by niche partitioning in a mature, stable ecosystem. Our findings indicate a “no-analogue problem” comparing the two data sets but provide a robust, multi-proxy framework for critically applying modern spatial data to the interpretation of temporally dynamic records of the past.</div></div>","PeriodicalId":45442,"journal":{"name":"REVUE DE MICROPALEONTOLOGIE","volume":"90 ","pages":"Article 100897"},"PeriodicalIF":1.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145884389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
