The phrase "abundance index" is correct and usable in written English.
It can be used in contexts related to statistics, ecology, economics, or any field where measuring abundance is relevant.
Example: "The abundance index of the species in the region has shown a significant increase over the past decade."
Alternatives: "abundance measure" or "abundance metric".
Subsequently, a protein abundance index (emPAI) was calculated to detect the polypeptide sequences that were highly abundant among the captured glycoproteins (Tables S1, S2, S3, S4, S5).
Exponentially modified protein abundance index.
demPAI: the values of exponentially modified protein abundance index.
Poaceae Abundance Index (PAI) was derived by combining these four normalized difference indices.
For protein abundance in the multiplexed sample, exponentially modified protein abundance index (emPAI) was used.
The results showed that (1) species richness and abundance index increased firstly and then decreased with increasing stand layer.
The values for the exponentially modified protein abundance index (emPAI) (Ishihama et al. 2005) were used to estimate the abundance of cellulosomal and non-cellulosomal proteins.
This study temporally released chromatin-associated proteins by DNase I and MNase treatment and profiled them by exponentially modified protein abundance index (emPAI) based label-free quantitative proteomics.
Transects were seasonally surveyed for wild ungulate and cattle scats, and scat frequency was used as a relative abundance index of wild ungulates and cattle.
It is concluded that the surveys produce a fairly precise abundance index, and that given the relatively small effective sample size, reducing tow duration to 15 min would increase overall survey precision.
The magnitude of this underestimation may be important and, therefore, observation errors cannot be always considered as a priori negligible in assessing the precision of a count-based abundance index.
