The phrase "a broad scale analysis" is correct and usable in written English.
It can be used when referring to an analysis that covers a wide range or scope of data or subjects.
Example: "The researchers conducted a broad scale analysis of the environmental impacts of urban development."
Alternatives: "a comprehensive analysis" or "a wide-ranging analysis".
Since different E. coli strains are effectively representing the same lineage in a broad-scale analysis, removing these 36 sequences did not affect the outcome.
For this reason, and because of a previously observed genetic divergence of populations on either side of the Andes (Milá et al. 2009), we carried out independent analyses on each sub-region, in addition to a broad-scale analysis of the entire region.
The identification of universal primer pairs amplifying fragments with high resolution capacity is a major task of DNA barcoding, and can help the broad scale analysis of life on earth.
We classified Landsat-5 TM images from 2001 and 2009, covering protected and unprotected areas and used for broad scale analysis, and IKONOS and GeoEye images from 2001 and 2009 for fine scale analysis.
They amply refer to the important paper of Covello and Gray of 1993 on the evolution of RNA editing while the thorough and much more recently published broad scale analysis by Tillich et al. (2006) is almost unmentioned.
Here, I overcome this difficulty by using a publicly accessible, fisheries-independent database to provide a broad scale, comprehensive analysis of human impacts on predatory reef fish communities across the greater Caribbean region.
We conducted a broad scale phylogeographic analysis of the least salmonfly Pteronarcella badia (Plecoptera) across western North America.
To identify genes acquired by chromalveolates through HGT at different time points in their evolutionary history, we performed a broad scale phylogenetic analysis of the EST data generated for a free living phototrophic dinoflagellate alga Karenia brevis that is renowned as an agent of toxic algal blooms that annually cause massive fish and marine mammal mortality in the Gulf of Mexico [ 28].
We note that any broad-scale analysis of this sort is complicated by the overlap in information (collinearity) between alternative predictors such different environmental variables or environmental and behavioral-ecological determinants, and the cause - effect assumptions inherent in statistical modeling approaches.
For a broad scale examination of variation, we performed a principle components analysis of all samples.
