Thus, while most of biodiversity remains to be described25, the same taxa are preferentially studied and recorded over and over again.
While rat and wallaby diets contained many of the same taxa, their diets were significantly different in terms of the fungal taxa that comprised each sample.
For the purpose of validating evolutionary models, biologists check whether or not a phylogenetic tree (resp. cluster) is contained in a phylogenetic network on the same taxa.
Specifically, we (1) compared the species-abundance distributions for all moths sampled from the forests, (2) used ordination and indicator species analysis to assess whether the same taxa were most dominant within each forest stand, and (3) tested whether dominant taxa were disproportionately niche generalists compared to all species sampled from the larger species pools within each watershed.
Intra-accessional diversity was also investigated by examining populations of the same taxa.
The computer simulation analyses they conducted not only supported the validity of the bootstrap test when each gene evolved at a constant rate, but also suggested that the model remained valid as long as the rate heterogeneity was occurring proportionally in the same taxa for both genes (Sang and Zhong, 2000).
Some researchers still think that 1470 and the new fossils could be members of the same taxa (or biological group), H. habilis, because so few fossils of H. habilis have been found that "we still don't understand H. habilis," says paleoanthropologist Timothy White of the University of California, Berkeley.
The same taxa were rare in STI negative individuals.
In general, more clade models were significant than ancestral branch models, even where these corresponded to the same taxa.
Seven phylogenies based on seven different datasets (Datasets 5-11) with same taxa were topologically incongruent, however, a "core" urostylid group is revealed in each tree (Fig. 4).
When stratigraphic fit metrics are calculated for competing tree topologies that share the same taxa (usually pruned phylogenetic trees), support is shown for one tree versus another if the differences between their stratigraphic fit metrics are statistically significant [122].
