Sentence examples for morphological characters useful from inspiring English sources

They were unable to discover morphological characters useful for a generic distinction, simply because the taxa are largely congruent (e.g., number of more or less loosely coiled chloroplasts, reproduction by conjugation and anisogamy of gametangial cells).

The combination between molecular data and morphological characters proved useful for differentiating Plocamionida species and for establishing their phylogenetic relationships.

Too few morphological characters are useful for conducting conclusive phylogenetic analyses at the highest taxonomic level.

Prior to the use of molecular data to build evolutionary trees, it was a great challenge to determine which morphological characters could be useful for classification, given their intraspecific variability [ 32, 88] and phenotypic plasticity [ 89- 94].

Despite the great contribution of the study by Ørgaard (1991), identification of Cabomba species is still problematic due to vegetative similarity among the taxa, the presence of few morphological characters that are useful in delimiting species, and the necessity of both flower and seed to differentiate some species.

Data from these species are used to address whether the morphological characters noted above are useful and consistent predictors of phylogeny, and what global or regional events may be temporally associated with the radiation of species along the North and Central American coasts.

Among the higher fungi, reproductively isolated cryptic species exist that are morphologically difficult to distinguish owing to a lack of taxonomically useful morphological characters.

We have identified a suite of morphological characters which may prove useful in further comparative studies.

In this group, taxonomically useful morphological characters are few.

The morphology-based species delimitation may also severely underestimate the overall diversity in taxonomic groups with morphological uniformity or with a paucity of taxonomically useful morphological characters.

Although more molecular, as well as morphological, characters may well prove useful, there is little doubt that broader taxonomic sampling is now the key roadblock.
