Its nature remains a mystery, but assuming that it is composed of weakly interacting subatomic par...
متن کاملFoundational issues concerning taxa and taxon names.
In a series of articles, Rieppel (2005, Biol. Philos. 20:465-487; 2006a, Cladistics 22:186-197; 2006b, Systematist 26:5-9), Keller et al. (2003, Bot.

They argue that species and higher taxa are not individuals, and they reject the view that taxon names are rigid desig...
متن کاملCloudshine: New Light on Dark Clouds
We present new deep near-infrared images of dark clouds in the Perseus molecular complex. These images show beautiful extended emission which we model as scattered ambient starlight and name “cloudshine”. The brightness and color variation of cloudshine complicates the production of extinction maps, the best tracer of column density in clouds. However, since the profile of reflected light is es...
متن کاملCircumscriptional names of higher taxa in Hexapoda
Testing non-typified names by applying rules of circumscriptional nomenclature shows that in most cases the traditional usage can be supported. However, the original circumscription of several widely used non-typified names does not fit the taxa they are applied to. Here I discuss names historically applied to the taxa whose correct circumscriptional names should be Hexapoda, Amyocerata, Triplu...
