Because a genus-level angiosperm supertree does not exist, we were not able to map myrmecochory directly on one phylogenetic tree to identify independent origins.
Because Alpova appears as a genus with a reduced diversity in Europe (three species, Figure 3) the analysis was extended to extra-European species of Alpova, and phylogenetic reconstructions performed using ITS sequences.
Because the species within a genus are morphologically nearly identical, it is uncertain to what extent B. floridae and B. caribaeum, known from Jamaica to Brazil, overlap (Poss and Boschung 1996).
Because the geographic range of a genus during one interval is partially dependent upon its geographic range in the previous time interval, the geographic range estimates for a single genus are not independent [51].
The observation is interesting because Gammatricula was described as a genus showing character states that were overall derived among Pachydrobiini [ 8].
A disadvantage of both methods of geographic range calculation is that they do not explicitly consider discontinuities in the distributions of taxa, and range discontinuities are potentially important when carrying out analyses at the genus level because a single genus could have multiple species with non-overlapping geographic ranges.
Because the cotton rat, a genus found in the Americas, was susceptible to polio, Dr. Koprowski injected the virus into cotton rat brains.
Because Altocumulus is a genus-type of limited convection, it is divided into the same four species as cirrocumulus.
We used a genus-level phylogeny because there is little topological resolution for species and because most N-fixing genera contain only N-fixing species.
This is an important finding because the genus Paulinella provides a set of diverged lineages that can be used to study the process of post-endosymbiotic plastid evolution using genomic and proteomic methods.
This value is employed as a benchmark because the genus Acropora encompasses one-quarter to one-third of one-quarter of scleractinian coral diversity [35], dominates shallow coral cover in parts of the Indo-Pacific [34], and is typically bleaching sensitive [23], [24], [33].
