SPHAERODACTYLUS GRANDISQUAMIS, A VALID SPECIES

Is Echinococcus intermedius a valid species?

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 ...

Tail Regeneration in the Geckonid Lizard, Sphaerodactylus

I N the Histoire de VAcademie Royale des Sciences for 1686 (vol. ii, p. 7, published 1733) under the heading of 'Diverses Observations Anatomiques' is an account of the researches of three savants, Thevenot, Du Verney, and Perrault, on regeneration of the tail in the European Green Lizard. Perrault found that in the new tail, instead of vertebrae, 'il n'y avoit qu'un cartilage de la grosseur d'...

Amphinemura palmeni is a valid Holarctic stonefly species (Plecoptera: Nemouridae)

The taxonomic status of Amphinemura palmeni, a rare stonefly from northern Fennoscandia, was re-evaluated in a morphological study combined with analyses of mitochondrial COI and nuclear 28S sequences. Taxon sampling included A. standfussi, with which A. palmeni has been confused, the Nearctic A. linda and seven other Amphinemura species. Amphinemura palmeni is confirmed as a valid species, and...
