Putting your finger upon the simplest data
Over the past decades, digitization endeavors across many institutions holding natural history collections (NHCs) have multiplied with three broad aims: first, to facilitate collection management by moving existing analog catalogues into digital form; second, to efficiently document and inventory specimens in collections, including imaging them as taxonomical surrogates; and third, to enable discovery of, and access to, the resulting collection data.
NHCs contain a unique wealth of potential knowledge in the form of primary biodiversity data records (PBR): at its most basic level, the ¿what, where and when¿ of occurrences of the specimens in the collections. But as T.S. Eliot famously said, ¿knowledge is invariably a matter of degree¿. For such data to be transformed into digitally accessible knowledge (DAK) that is conducive to an understanding about how the natural world works, release of digitized data (the ¿this we know¿) is necessary.
At least two billion specimens are estimated to exist in NHCs already, but only a small fraction can be considered properly DAK: most have either not been digitized yet, or not released through a discovery facility. Digitizing is relatively costly as it often entails manually processing each specimen unit (e.g. a herbarium sheet, a pinned insect, or a vial full of invertebrates). How long could it take us to transform all NHCs into DAK? Can we keep up with the natural growth in collections

Spatial priorities for freshwater fish conservation in relation to protected areas
Abstract1. Freshwater habitats are vital for both humans and nature owing to theirexceptional biodiversity and valuable ecosystem services, but they are currentlyfacing serious threats. The designation and management of protected areas havebeen proposed as the most feasible way to ensure conservation objectives for thefuture. However, traditional approaches have not protected freshwater faunaeffectively, especially freshwater fish.2. Previous studies have identified the most irreplaceable terrestrial places toachieve conservation goals. Here, the aim was to investigate how the presentnetwork of protected areas preserves irreplaceable rivers for freshwater fish.3. The irreplaceability of the world's river basins was calculated using InternationalUnion for the Conservation of Nature Red List distribution maps, considering therarity, richness, and conservation status of their freshwater fish fauna. Theoverlap between irreplaceable basins and the present network of protected areaswas also calculated.4. The results highlight the conservation significance of tropical rivers, particularlythose in the Neotropics. The subset of the basins covering 30% of the mostirreplaceable land surface (in line with the United Nations 30by30 target)encompasses 99% of freshwater fish species. However, protected areas do notseem to provide sufficient protection to these basins, as 89% of their surface arealies outside protected areas. Only 7% of freshwater ecoregions meet the UnitedNations 30by30 target.5. Given the context of climate change, allocating new protected areas becomescrucial in providing better survival opportunities for freshwater fish species.Despite the limitations inherent to the absence of total knowledge of freshwaterfish biogeography and the irreplaceability index itself, this study identifies prioritysites for their conservation that may help inform decision-making in the future toestablish more effective protected areas

From expert to data-driven biodiversity knowledge: assessing ecosystem irreplaceability with IUCN red list data for freshwater fish
Critical as they are for humans and nature, freshwater ecosystems are threatened-but the extent and depth of these threats are not well understood, especially if essential biodiversity data are lacking. Any policy aimed at protecting such ecosystems must first
assess the threat factors and the potential harm, well before proposing conservation measures such as the creation and development of Protected Areas (PAs). These assessments must be done using a deep and sound knowledge of the actual and potential biodiversity variables. Freshwater ecosystems have been largely neglected in traditional PA design and management (Abell et al. 2007), be it for scarcity of biodiversity data, or for more perception-related reasons such as visibility and accessibility driving the allocation of conservation resources to more data-rich environments
Game of tops: trends in GBIFs community of users
Building on the development of Biodiversity Informatics, the Global Biodiversity Information Facility (GBIF) undertook the task of enabling access to the world¿s wealth of biodiversity data via the Internet. To date, GBIF has become, in many respects, the most extensive biodiversity information exchange infrastructure in the world, opening up a full range of possibilities for science
BIDDSAT: visualizing the content of biodiversity data publishers in the Global Biodiversity Information Facility network
In any data quality workflow, data publishers must become aware of issues in their data so these can be corrected. User feedback mechanisms provide one avenue, while global assessments of datasets provide another. To date, there is no publicly available tool to allow both biodiversity data institutions sharing their data through the Global Biodiversity Information Facility network and its potential users to assess datasets as a whole. Contributing to bridge this gap both for publishers and users, we introduce BIoDiversity DataSets Assessment Tool, an online tool that enables selected diagnostic visualizations on the content of data publishers and/or their individual collections
