Taxonomic sufficiency and the increasing insufficiency of taxonomic expertise

Marine Pollution Bulletin, 2003
Taxonomic sufficiency (TS) involves the identification of taxa only to a level of taxonomic resolution sufficient to permit the detection of changes in stressed assemblages. Recently, however, TS has been proposed also for conservation issues as a tool to estimate biodiversity over large areas and in poorly known environments.

Taxonomic minimalism

Trends in Ecology & Evolution, 1994
Biological surveys are in increasing demand while taxonomic resources continue to decline. How much formal taxonomy is required to get the job done? The answer depends on the kind of job but it is possible that taxonomic minimalism, especially (1) the use of higher taxonomic ranks, (2) the use of morphospecies rather than species (as identified by ...

Taxonomic Validation: An Overview

International Journal of Nursing Terminologies and Classifications, 1993
A valid taxonomy legitimizes the elements that make up the taxonomy and increases trust in its generalizability and predictability. There is a concern that the NANDA Taxonomy is not a valid taxanomic structure. Despite on‐going work to validate individual nursing diagnoses, there is little research that focuses on validation of groups of diagnoses ...

The Prometheus taxonomic database

Proceedings IEEE International Symposium on Bio-Informatics and Biomedical Engineering, 2002
M.R. Pullen et al. (2000) have designed a new model of plant taxonomy (called Prometheus); it supports multiple overlapping classifications, and distinguishes the process of naming from classifying. The concepts identified in this taxonomic model necessitated the design of a new database model - the Prometheus Object-Oriented Model (POOM) - to ...

Conserving taxonomic complexity

Trends in Ecology & Evolution, 2005
Traditional species-based conservation programmes are appropriate in situations where species are readily identifiable. However, in certain taxonomically complex groups of organisms, generally characterized by the presence of uniparental lineages and reticulate evolution, it is not possible to classify biodiversity into discrete and unambiguous species.

The Foundations of Taxonomic Encoding

Computational Intelligence, 1998
Taxonomies (partially ordered sets and lattices) are important in many areas of computing science, particularly object‐oriented languages, machine learning, and knowledge representation. Taxonomic encoding strives to enhance the efficiency of taxonomic representation and use, which becomes increasingly important as the size of taxonomies grows. In this

Taxonomic Abstraction in Psychobiology

The Journal of General Psychology, 1984
If a body of knowledge in a scientific discipline is to be extended beyond empirical observation and into the realm of laws and principles, one of the fundamental requirements is a taxonomy which supports the systematic integration of observations. Psychobiology benefits from taxonomies provided by biology and chemistry, which include not only object ...

A Taxonomic Analysis of Abstraction

Perspectives on Psychological Science, 2016
An important characteristic of knowledge is that it exists at multiple levels of abstraction. This article illustrates how different levels of abstraction influence perception, comprehension, categorization, memory, and thought. Theories exist for how abstraction influences each of these cognitive processes, but there are few unifying principles for ...

Taxonomic reasoning in LOGIDATA+

2005
Taxonomic reasoning is a typical inference task performed by many AI knowledge representation systems. We illustrate the effectiveness of taxonomic reasoning techniques as an active support to knowledge acquisition and schemas design in the advanced database environment LOGIDATA+, supporting complex objects and a rule-based language. The developed idea

Revisiting the Taxonomic Impediment

Science, 2005
We read with some frustration the recent Editorial and Letters concerning the “taxonomic impediment” (Q. D. Wheeler et al. , “Taxonomy: Impediment or expedient?”, Editorial, 16 Jan. 2004, p. [285][1]; “Taxonomists and the CBD,” R. Geeta et al. , Letters, 20 Aug. 2004, p. [1105][2]; “Museum collections and taxonomy,” D. Causey et al.
