Topic: Taxonomic classification

Ads by Google      Families of Homeopathic Remedies I have expended a good deal of time and passion over the past year refining and developing a remedy families database, in order to meet the growing interest among homeopaths in investigating concordances between remedies bearing relationships to one another by way of taxonomic classification, chemical composition, source, or other forms of presumed resemblance. Beyond the issue of classification within taxonomic families, I feel that an accurate description/identification of the plant species we use, in contemporary nomenclature, is in order. In addition, I found that many of the plants among these barely-described remedies are difficult to clearly identify, with names not reconcilable with contemporary lists of named species, and insufficient information in our literature to guide identification. http://www.wholehealthnow.com/homeopathy_pro/wt15.html      Levels of Classification of Faith Groups Classification facilitates various forms of sociological and historical research and understanding. It may be understood that some denominations/religious bodies are more exclusive in nature than others. A Muslim may formally be associated with a particular mosque. http://www.adherents.com/classify.html      101 Taxonomy - www.101science.com A more pragmatic approach to classification was developed by Greek physician Dioscorides, who separated, for instance, medicinal herbs from those used in making perfumes. Determining an underlying order in the complex web of life is a difficult undertaking that encompasses advanced scientific methods as well as fundamental philosophical issues about how to view the living world. They advocated using other factors, such as behavior or anatomy, along with phylogeny to better classify organisms. http://www.101science.com/Taxonomy.htm      Taxonomic Classification and Phylogenetic Trees However, the biggest difference between the two approaches is that, when creating groupings, evolutionary taxonomists seek to maximize the way in which the groupings they create communicate information about the group of organisms in that taxon (in the way the word "mammal" or "reptile" does for even an untrained person). What makes these keys distinctive is that they are ordered in such a way that a series of choices is made that leads the user to the correct identity of the item they are looking at. Over the last few centuries systematists have developed a number of different approaches for trying to show the relationships of organisms. http://www.mhhe.com/biosci/pae/zoology/cladogram/      The Prometheus Taxonomic Model: a practical approach to representing multiple classifications However, the complexity of the living world, and the wide variety of techniques for surveying it (phenetics, cladistics, etc.), mean that one cannot simply assume a single, common reference classification categorising all organisms. 4.         The ‘taxonomic process’ usually manipulates and refines existing taxonomic concepts, both as a starting point for the delimitation of individual taxa, and as a means of delimiting the bounds of the study group. The usual approach to handling taxonomic data has been to use names as identifiers of taxon concepts, with statements regarding the taxonomic status of a taxon assigned to the name. http://www.dcs.napier.ac.uk/~prometheus/prometheus_1/publications/ntct.htm      Overview of Biodiversity Informatics After the tasks of collecting new specimens and assembling specimens from previous expeditions, the real work of taxonomy concerns studying, analyzing, and describing the attributes of organisms, or more importantly how those features vary among individuals, populations, species and higher taxa. These tools enabled researchers to analyze their observations and interpretations according to the emerging methodologies, and thereby to develop scientific hypotheses about the evolutionary histories of their study organisms. A taxonomic key is a decision tree; each fork in the tree represents a choice among two or more mutually exclusive character states. http://www.calacademy.org/research/informatics/sblum/pub/biodiv_informatics.html      Classification Lab Closely tied to cladistic analysis is parsimony, or the search for the simplest practical phylogeny for an organism. In cladistic analysis, each feature, or character, is viewed as a primitive character (common to an entire group) or a derived character (that arose in the evolution within the group). Keeping this primer in mind, you will be able to better understand the basis for the classification of our organisms. http://www.sidwell.edu/us/science/vlb5/Labs/Classification_Lab/classification_lab.html      An Objective Time Based Phylogenetic Classification that Places Chimpanzees, Bonobos, and Humans in the Genus Homo This is possible because in traditional primate classifications, despite the use of the grade concept to name some of the taxa, most taxa do represent monophyletic groups. This makes it possible to discover the phylogenetic relationships that exist among living species at all levels of the taxonomic hierarchy from the most recently to the most anciently separated. Instead, the molecular view emphasizes how much we hold in common with other species, especially with our sister-group the common and bonobo chimpanzees. http://www.uchicago.edu/aff/mwc-amacad/biocomplexity/MGPAPER.html      Integration of Modern Taxonomic Methods For Penicillium and Aspergillus Classification (1st) by R. A. Samson , J. I. ... Many species of Penicillium and Aspergillus are important in biotechnology, food, medicine, biodeterioration and other applied fields, so a practical and stable taxonomy is of vitalimportance. Many species of Penicillium and Aspergillus are important in biotechnology, food, medicine, biodeterioration and other applied fields, so a practical and stable taxonomy is of vital importance. Recent developments inscience and technology mean that taxonomic classification is no longer confined to classical morphological concepts, and the integration of molecular, physiological and biochemical methods now plays an important role in understanding theclassification of these fungi. http://www.campusi.com/isbn_9058231593.htm      Georgia Wildlife Web Site; Classification of animals No single classification is final, because additional studies may show new relationships among animals that were not clear using previous evidence. The field of study called systematics focuses specifically on the evolutionary relationships between living organisms. Although some groups of animals are more subject to changes than others, new discoveries can lead to changes even among the best-known groups of animals. http://museum.nhm.uga.edu/gawildlife/gawwclassification.html      Taxonomic Resources A taxonomic treatment and a quite extensive library of Protist images (including representativies of many algal groups) from the Protist Information Server in Japan A taxonomic treatment and a quite extensive library of Protist images (including representativies of many algal groups also) from the Protist Information Server in Japan The ITIS Integrated Taxonomic Information System database (USA) http://www.marine.csiro.au/datacentre/taxonomy/tax_details.htm      Vegetation Species in Olympic National Park - Image-Based Vegetation Classification and Mapping - National Park Service ... The results of the cluster analysis was a final set of supervised training sites that represents all the vegetation types to be mapped in the study areas as well as representing the range of spectral variation in the satellite imagery within the study area. This newly colored spectral variation map was used to identify areas that may represent acceptable training sites for subsequent image supervised classification based on their spectral homogeneity. Numerous other species-specific models were developed and executed that not only incorporated information from elevation and aspect data, but also utilized image training site classification data to refine and enhance the species classification. http://www.nps.gov/gis/metadata/olym/onp_species.html      Application of the Soil Taxonomy Key to the Organic Soils of the Everglades Agricultural Area. A Typic subgroup soil lacks any significant properties that would suggest it is in a transition phase between related great groups or some other soil taxonomic level. Extragrade subgroup soils reflect specific properties that are otherwise anomalous to the main concept of the great group. The soil taxonomy system helps us to understand the types of soils we have, how they were formed, and how they may be changing. http://edis.ifas.ufl.edu/BODY_AG151      Taxonomy Within each level of the hierarchy, there may exist sub-divisions, with each successive level more specific to the organism being described. (Classification information retrieved Sept 18, 2002, from the Integrated Taxonomic Information System on-line database, http://www.itis.usda.gov.) Taxonomic classifications are based on the following 7-level hierarchical scheme, with each successive level describing the organism in more detail: http://www.florida.sierraclub.org/turtlecoast/home/Taxonomy.htm      Taxonomy - Wikipedia, the free encyclopedia Scientific classification of organisms, the root is the Organism (as this applies to all living things, it is implied rather than stated explicitly). Taxonomy may refer to either a hierarchical classification of things, or the principles underlying the classification. Almost anything—animate objects, inanimate objects, places, and events—may be classified according to some taxonomic scheme. http://en.wikipedia.org/wiki/Taxonomy      A Taxonomic Information Model for Botanical Databases The IOPI checklist is in fact based on that assumption. A specific classification system may prescribe a defined sequence of taxa.

As it stands, it seems quite arbitrary, and as I mentioned, different criteria often having nothing to do with the taxa themselves (such as time of divergence) can produce different classifications. As taxonomic rankings are often arbitrary, is drawing conclusions - or even making inferences - based on taxonomic rankings a logical scientific pursuit? http://www.evcforum.net/ubb/Forum5/HTML/000208.html      Taxonomic Classification Although the specific name "spinosum" has been used in a taxonomic sense it is applied in this instance as a descriptor of the spiny protuberances typical of the commercial species. The specific name "alvarezii" as applied to Kappaphycus alvarezii Doty commemorates the late Vicente (Vic) Alvarez, a pioneer in the methods of cottonii agronomy. The trade name "spinosum" generally refers to Eucheuma denticulatum but may be applied to any species of Eucheuma that yields iota carrageenan during extraction. http://www.surialink.com/abc_eucheuma/1/43.htm      Sharkey Taxonomic Arkansas NRCS Water perches on plow pans in cultivated areas, both are episaturation, but neither satisfies the saturation requirement for aquic conditions in Vertisols.

As a result, classification of plant groups was more satisfactory and their arrangement was showing natural relationships with each other. Later on, in the natural systems of classification (e.g. http://www.pinkmonkey.com/studyguides/subjects/biology-edited/chap13/b1313501.asp      Taxonomic Classification Taxonomy is the science of systematically naming and organizing organisms into similar groups. Plant taxonomic classification changes with continuing research, so inconsistencies in nomenclature will be found among different textbooks. For example, fire blight is a disease of the Rose family, therefore it is helpful to recognize members of the Rose family to diagnosis this disease. http://www.ext.colostate.edu/pubs/garden/07701.html      COAST - Taxonomic Classification Biologists use this system to study individual organisms, or populations of organisms. Classification methods help us comprehend the extraordinary variety of life around us. Although all systems of classification are recognized as artificial, a manageable, consistent way of ordering living things is needed in order to further knowledge of our world. http://coast-nopp.org/visualization_modules/biota_biotic/classification_systems/taxonomic/taxonomy.html      Taxonomic Classifications This practical approach, which takes all factors into consideration, has long been the basis of palaeontological classification, and is still seen as the best method by many. A major problem with classification is that it has, and is, changing. This is largely because of advanced techniques of molecular sequencing, which give far more details than could ever be seen from a complete organisms. http://www.bbm.me.uk/portsdown/PH_720_Tax.htm      Scientific Classification The Linnaean taxonomic system is quite useful as a classification system. These classifications allow people to better understand how marine mammals are related to other animals. Our current day classification system was created by Swedish botanist Carl Linnaeaus in 1757; this is what we refer to as Taxonomy. http://nmml.afsc.noaa.gov/education/taxonomy.htm      Patuxant Bird Classifications and Sample Species [ "SpeciesClass.htm" ] By contrast, the "species" represents a taxonomic division that generally refers to a group of animals which are similar in structure and descent and are able to breed among themselves. Taxonomy is the division of biology that is concerned with the classification and naming of organisms based on shared characteristics and natural relationships. Classification differences occur in their order, family, genus, and species. http://www.nevadaaudubon.org/BirdSites/SpeciesClass.htm      Classification and Taxonomy Tools - SearchTools.com Listing It allows people to tag a set of topics and associated URLs so that other applications supporting this format can recognize the relationships.

The taxa Superkingdom and Infraspecies are generally not used, leaving a maximum of 26 possible taxonomic categories, although all are rarely required for any given species (or subspecies). The purpose of taxonomy is to provide a convenient scheme for identifying and categorizing species, not to document their complete evolutionary genealogy. http://town.morrison.co.us/dinosaur/taxinfo.html      Natural Selection: subject gateway to the natural world Instructions to help beginners in identifying and describing various taxonomic groups of polychaetes are also included.

Why taxonomists are sometimes categorized as "splitters" or "lumpers" and how might this affect their classification? Note that in order to best introduce your audience to the controversy, you may need to explain how a systematic hierarchy is constructed and what constitutes a "class" versus an "order" (for example, differences between insects and chilopods compared to the difference between a grasshopper and a dragonfly).
