RESCUE-ESE identifies candidate exonic splicing enhancers in vertebrate exons
An online ESE analysis tool is described that annotates RESCUE-ESE hexamers in vertebrate exons and can be used to predict splicing phenotypes by identifying sequence changes that disrupt or alter predicted ESEs.
Integrating DNA barcode data and taxonomic practice: Determination, discovery, and description
The role of DNA barcoding in generating hypotheses of new taxa in need of formal taxonomic treatment is discussed, and it is emphasized that the recursive process of character evaluation is both necessary and best served by understanding the empirical mechanics of the discovery process.
Conservation Genetics at the Species Boundary
No species concept should be viewed as an absolute criterion for protecting populations, but as part of a frame- work within which identification of protection and management goals can be achieved effectively and de- fensibly.
Calibrating phylogenetic species formation in a threatened insect using DNA from historical specimens
Widespread polymorphism was revealed throughout the historical range of this species, suggesting a relatively recent anthropogenic character fixation event associated with the extinction and fragmentation of populations.
Taxonomic and Behavioral Composition of an Island Fauna: A Survey of Bees (Hymenoptera: Apoidea: Anthophila) on Martha's Vineyard, Massachusetts
The results underscore the role of maritime habitats underlain by sandy soils in sustaining regional diversity of bees in addition to Lepidoptera and other well-documented insect groups and reinforces the need for multi-year studies of bee faunas.
Functional Ecosystems and Biodiversity Buzzwords
Following earlier examinations of eco- system management, it is emphasized that several of its apparent outgrowths may be too vague to inform specific recommendations, that the historical mechanics of "ecosystem processes" are essentially unknovwable, and that anecdotal definitions of ecosystems allow one to justify virtually any protocol as management.
The synaptonemal complexes of Caenorhabditis elegans: pachytene karyotype analysis of male and hermaphrodite wild-type and him mutants
The decrease in number of SCknobs in hermaphrodite to male represents a true sex difference and the presence or absence of the SC knobs may influence the X chromosome nondisjunction process and this effect is not localized to the region of theSC on which the SC knob is located.

PCs are restricted to meiotic and germ-line derived tissues and are most commonly present after SC formation, however, in a number of animals and plants, both extra- and intranuclear PCs are present during premeiotic and pre-pachytene stages.
The synaptonemal complexes of caenorhabditis elegans: comparison of wild-type and mutant strains and pachytene karyotype analysis of wild-type.
The increase in rate of nondisjunction in the him mutants is not related to aberrant SC morphology, and the wild-type hermaphrodite has six SCs, as determined from 3-D reconstruction analysis of serial section from electron microscopy.
How Many Things Are There? A Reply to Oliver and Beattie, Beattie and Oliver, Oliver and Beattie, and Oliver and Beattie
In a recent paper in this journal, Oliver and Beattie (1996:100) recapitulate and extend their earlier arguments that "the use of invertebrates in some monitoring and conservation research and
