Chapter 2 – Patterns of Associations

Marine organisms are distributed throughout their 3D environment. Some are benthic, living in close association to the sea floor, often on (epifaunal) or in (infaunal) the sediment, at all depths. Others live within the water column at all depths. These pelagic organisms either swim well (nekton) or are at the mercy of oceanic currents (plankton). Planktonic drifters are termed phytoplankton if...

Chapter 7 Taxonomy Design

This chapter discusses the design of taxonomies to be used in dynamic taxonomy systems. Although the only actual requirement of dynamic taxonomies is a multidimensional classification, i.e., objects are classified under more than one concept, an organization by facets is normally used. In the first section, we provide guidelines for the design of DT taxonomies, which include the automatic const...

Chapter 4 : The Taxonomy Project

There are two main tools for viewing the information in the Taxonomy database: the Taxonomy Browser, and Taxonomy Entrez. Both systems allow searching of the Taxonomy database for names, and both link to the relevant sequence data. However, the Taxonomy Browser provides a hierarchical view of the classification (the best display for most casual users interested in exploring our classification),...
