missing taxa and

USAGE SUMMARY

The phrase "missing taxa and" is correct and usable in written English.
It can be used in contexts related to biology, ecology, or paleontology when discussing organisms that are not represented in a particular dataset or study. Example: "The research highlighted the importance of addressing the issue of missing taxa and their potential impact on biodiversity assessments."

Missing data also come in the form of missing taxa, and certain groups are less well-sampled than others.

BMC Evolutionary Biology

In addition, most of our datasets have a relatively low number of missing taxa and in all cases, the proportion of sampled species is more than the 80% level recently proposed as a threshold [ 54, 56].

BMC Evolutionary Biology

However, note that due to missing taxa and multifurcating trees, it is not straightforward to measure supporting and conflicting relationships between a supertree and the gene trees (an alternative definition is presented in [ 36]).

Algorithms for Molecular Biology

If two out of three of the conditions (g, m, or b) are favourable (i.e. many input trees, few missing taxa, and the probability that the input trees are congruent with the principal trees is high) then both methods work well.

BMC Evolutionary Biology

Figure 5 is similar to Figure 4 except that rather than averaging over all values of b and m we focus on the difficult case with the highest number of missing taxa and the most incongruence generated by incomplete lineage-sorting (m = 3, b = 0.5).

The results are averaged over 100 repetitions and the 12 combinations of number of missing taxa m and coalescent branch lengths b.

BMC Evolutionary Biology

Throughout the present analysis, we evaluated the effect of missing characters and missing taxa on tree topology and branch support.

Figure 4 illustrates HGT and missing taxa cases.

Algorithms for Molecular Biology

For each interior edge, a column is added to the MR, where '0' and '1' indicate the taxa on either side of the edge and missing taxa are coded as '?'.

Algorithms for Molecular Biology

It is easy to see that MR supertrees also generalize MR consensus in this case: For bifurcating input trees on the same taxon set, MR cannot place missing taxa or resolve multifurcations and thus MR directly minimizes the RF distance to the input trees.

BMC Evolutionary Biology

Phylogenies were simulated to the hypothetical full clade size (known missing taxa + 10% unknown missing taxa) under a constant rate pure birth diversification process and taxa were randomly pruned from the tree to mimic incomplete sampling.

Expert writing Tips

Best practice

When discussing phylogenetic analyses, explicitly state how "missing taxa" are handled to ensure transparency and reproducibility in your research.

Common error

Avoid assuming that "missing taxa" have no impact on your analysis. Always assess the potential bias introduced by their absence, as it can significantly affect phylogenetic inferences and evolutionary conclusions.

Linguistic Context

The phrase "missing taxa and" functions primarily as a noun phrase conjunction, connecting the concept of "missing taxa" with additional considerations or factors in scientific discourse. Ludwig AI indicates the phrase is grammatically correct and usable.

Ludwig's WRAP-UP

In summary, the phrase "missing taxa and" is a grammatically sound and scientifically relevant term predominantly used in formal and scientific registers. As Ludwig AI confirms, it effectively communicates the presence of data gaps in biological studies, particularly in phylogenetic analyses. Recognizing and addressing the impact of "missing taxa and" is crucial for robust scientific conclusions. Related terms such as "absent taxa and" or "lacking taxa and" can provide alternative ways to express the same concept. Remember to evaluate and communicate potential biases stemming from missing information when using the phrase in your writing.

More alternative expressions

Phrases that express similar concepts, ordered by semantic similarity:

absent taxa and

Replaces "missing" with "absent", maintaining the same core meaning but with a slightly different tone.

lacking taxa and

Substitutes "missing" with "lacking", indicating a deficiency of taxa.

unrepresented taxa and

Replaces "missing" to emphasize that the taxa are not represented in a dataset or analysis.

incomplete taxa and

Focuses on the incompleteness of the taxa data.

deficient taxa and

Highlights a deficiency in the taxa being considered.

taxa gaps and

Uses a more concise expression to refer to gaps in taxa representation.

data gaps in taxa and

Emphasizes that the missing taxa create gaps in the data.

underrepresented taxa and

sparse taxa and

Indicates a scarcity of taxa in the analysis.

omitted taxa and

Focuses on the deliberate exclusion or accidental omission of taxa.

FAQs

How does the presence of "missing taxa" affect phylogenetic analysis?

The presence of "missing taxa" can significantly impact the accuracy and resolution of phylogenetic trees. It can lead to incorrect inferences about evolutionary relationships and branch lengths. Addressing this issue often requires careful consideration of the sampling strategy and the use of appropriate statistical methods.

What statistical methods can account for "missing taxa" in phylogenetic studies?

Several statistical methods can account for "missing taxa" in phylogenetic studies, including imputation techniques, Bayesian methods with explicit models of taxon sampling, and approaches that incorporate clade-specific sampling fractions. These methods aim to mitigate the bias introduced by incomplete taxon sampling.

Why is it important to address "missing taxa" in biodiversity assessments?

Addressing "missing taxa" in biodiversity assessments is crucial because their absence can lead to an underestimation of species richness and an inaccurate understanding of ecosystem structure and function. This can have significant implications for conservation planning and resource management.

What are some alternatives to using the phrase "missing taxa and"?

You can use alternatives like "absent taxa and", "lacking taxa and", or "unrepresented taxa and" depending on the specific context and emphasis you want to convey.
