Taxonomical position

Two dozen geographic races of the Western honey bee, Apis mellifera, have been recognized, adapted to a range of environments from the cold continental climate of Eastern Europe, through the moist temperate climate of the Atlantic seaboard, the warmth of the Mediterranean, and the heat of the tropics and semi-deserts. Only four of these races need be considered for apiculture in Europe, namely A. m. mellifera, A. m. ligustica, A. m. carnica, and A. m. caucasica which present different morphological and behavioral characteristics [2,3].

Perhaps the most noteworthy aspect of the flavonoid study, however, was the high level of variation exhibited across the range of collections. Simply put, there was no relationship between taxonomic position and flavonoid profile. Differences between individuals within the same population (even adjacent plants ) often exceeded differences between other pairs of taxa. The level of variation present within this group of taxa represents one of the most extreme cases of flavonoid variation in the present author s experience [see Bohm (1987) for a review of flavonoid variation].

S. divinorum leaves established the typical levels of this compound in a number of samples of the plant. Further screening of additional sage species for 1 may help elucidate the origins and taxonomic position of S. divinorum within the genus Salvia. Additionally, this analytical assay can be utilized in screening for salvinorin A in other S. divinorum plant parts.

It is true that there are a small number of organisms of whose relationships we are still ignorant, but if it be remembered that these are mostly microbes not yet studied under laboratory conditions, it may be expected that further work will result in an elucidation of their taxonomic positions. All the other bacteria can be readily subdivided into three large groups [the classes Eubacteriae, Myxobacteriae, and Spirochaetae]. [37]...

Table 4.1 presents a classification of fishes derived from Nelson (1994) in order to indicate the taxonomic position of the species studied. This classification puts the fishes in an order that reflects their postulated evolutionary relationship, ranging from the most ancient splits in vertebrate evolution, Chondrichthyes (sharks, rays), Sarcopterygii (Lung-fish, Coelacanths and Tetrapods) and Actinopterygii (ray-finned fishes), to the most recent teleost orders, Pleuronectiformes (flounders) and Tetraodontiformes (puffers). 

The system of classification used here is designed as an aid to determine the taxonomic position and relationships of the genera, active and inactive, that have been used for the transformations of steroids. 

The taxonomic position by class and order are given for each genus the first time is appears in the table. A complete list of related families and genera can be found in Table II ( Taxonomy to Species ). Where more than one genus is tabulated on a page, the genus, in capital letters is repeated in the species column and underlined.
