There are two extremes in taxonomic behavior - publishing quickly as new taxa become available, and waiting a lifetime in the hope of publishing results that cannot be faulted. Neither of these extremes meets the needs of contemporary biologists in furthering our understanding of the evolution and maintenance of biological diversity. Part of the reason for these extremes is our failure to define suitable objectives for taxonomy. Instead of emphasising the units of biological diversity, we should concentrate on investigating patterns, structural, biological, ecological, temporal, and geographical, because it is these patterns that will generate novel ideas about the evolutionary history of organisms, and that will be most likely to be of interest to the... |

The morphology of sessile invertebrates, such as scleractinian corals, can be controlled by environmental and genetic mechanisms and, consequently, it is highly variable. Morphological variation has puzzled taxonomists by posing challenges to species classification within cryptic species complexes. The 'Atlantic Siderastrea Complex' is a suitable example. Because of overlapping diagnostic traits, the morphological interspecific limits of this group remain controversial and often resulted in doubtful synonyms. In addition, the recent identification of the Caribbean S. radians in the Southwestern Atlantic has revealed that intraspecific variation has been equivocally assessed. Traditionally, hierarchical categories of variation have been the criteria used to... |
