Species named (reply)

How many named species are valid?

Estimates of biodiversity in both living and fossil groups depend on raw counts of currently recognized named species, but many of these names eventually will prove to be synonyms or otherwise invalid. This difficult bias can be resolved with a simple "flux ratio" equation that compares historical rates of invalidation and revalidation. Flux ratio analysis of a taxonomic data set of unrivalled ...

Automated Dielectrophoretic Characterization of <named-content content-type="genus-species" type="simple">Mycobacterium smegmatis</named-content>

We report the positive dielectrophoretic (pDEP) characterization of wild-type and ethambutol-treated Mycobacterium smegmatis populations via automated pDEP cell trapping experiments. The automated technique was validated by measurements of carboxylate-modified polystyrene microspheres and Escherichia coli. The characterization ofM. smegmatis identifies a key frequency regime where the membrane-...

Learning the Species of Biomedical Named Entities from Annotated Corpora

In biomedical articles, terms with the same surface forms are often used to refer to different entities across a number of model organisms, in which case determining the species becomes crucial to term identification systems that ground terms to specific database identifiers. This paper describes a rule-based system that extracts ‘species indicating words’, such as human or murine, which can be...
