this thing is the a node that connects a determination to zero-to-one names and zero-to-one references. Anything that we can imagine to fulfill that role (taxon concepts, TNUs or whatever) can be included in the definition of that thing. Once we have established the "thing", we can ...
A total of 2,996 genes were found commonly present in all the three strains (core genome) and ~58% of the total genes were found only in one or two strains (vari- able genome) [30]. Another study using the gene content from 175 sequenced bacterial genomes showed that the ...
Theopederin D, nazumamide, and several onnamide and aurantoside congeners, as well as the keramamides, were only detected in the whole sponge extract (however, note that keramamides were detected in the 'Entotheonella' sample using a more sensitive mass spectrometry method; see Supplementary ...
Results: DeSignate is a tool for character-based taxon diagnoses that includes a novel ranking scheme. It detects and classifies individual and combined signature characters (diagnostic molecular characters) based on so-called character state vectors. An intuitive web application guides the user through...
15 and Table 5 that recent name changes in these three classes have slightly improved the classifications at genus, family and order levels as the predicted optimal thresholds were the same or slightly different except for the family levels of Eurotiomycetes and Dothideomycetes. Furthermore, the ...
The two categories “element” and “species” are similar in the sense that they are both abstract, mental constructs (classes of classes) which do not have “real” objects as their referents as do the element gold or the species C. familiaris. The species category and species taxa can ...
It is important to note that only one introduced species was recorded in these surveys, the east Australian scallop Scaeochlamys livida [50]. This species is now established in Western Australia and was recorded at both reefs (based on dead valves). While increased incidence and movement of ...
