Article
To understand the loss of species, a benchmark is needed, e.g. the status of biodiversity in 1992 when the Convention on Biological Diversity recognized biodiversity crisis to compare to its status in the successive year. Though we are far from knowning how many species there are on planet Earth, we keep track of their descriptions and number throu...

In the age of advanced information systems powering fast-paced knowledge economies that face global societal challenges, it is no longer adequate to express scholarly information - an essential resource for modern economies - primarily as article narratives in document form. Despite being a well-established tradition in scholarly communication, PDF...
Article
Hagedorn et al. claimed in previous work that when talking about biodiversity data, licenses with a non-commercial clause generally inhibit data reuse. We present here a formalization of that claim, stating that all things of class “license with non-commercial clause” that are in the context of a thing of class “biodiversity data” generally have a...

Article
Full-text available
A deep irony of COVID-19 likely originating from a bat-borne coronavirus (Boni et al. 2020) is that the global lockdown to quell the pandemic also locked up physical access to much basic knowledge regarding bat biology. Digital access to data on the ecology, geography, and taxonomy of potential viral reservoirs, from Southeast Asian horseshoe bats...
