choose not to develop classifications in such cases.
With intensity but with good humor, Smith kept our faithful secretaries, Hazel Santos, San Lineaweaver, and Virginia Smith, busy and sometimes bewildered, as he organized and reorganized (no computers then) the contributions of collaborating systematists
2009), but the knowledge of such fossils by the modern systematists
and taxonomists is rather poor.
However, even though new bioinformatics standards can bring new tools to systematists
, taxonomic knowledge remains essential to biological research (Raven 2004).
Both biological systematists
and philosophers of biology have proposed concepts that help us model and understand biological species independent of mechanisms of speciation.
Columellar folds are readily visible on the inner lip of many shells, and systematists
have used the impressive diversity of fold shapes to distinguish species and higher taxa.
will need to note not only the molecular techniques but also the doubt shed on morphology.
However, for this study I focused on the structure of male cerci, both because cerci are easy to handle and to isolate from the rest of the specimen and because the usefulness of cercal characters has already been well established by Orchelimum systematists
(Rehn and Hebard 1915; Blatchley 1920; Thomas and Alexander 1962; Walker 1971).
have long been accustomed to divide traits into those which are highly conserved, and thus good systematic characters, and those which are more variable.
It is very difficult to find support for deep-sea systematists
, and this is one reason for a critical shortage of trained taxonomists.
This collection is used by taxonomists and systematists
from many research institutions and countries for describing new species or species distributions (Bousfield, 1973; Theroux, 1994).
But DOI agencies, whose research functions are subsumed within the NBS, have very few systematists
(probably no more than 20 out of a staff of approximately 1,400), and those specialize mostly in vertebrates--the best known part of the biota but not necessarily the highest priority for all resource-management questions.
