AbstractWe present a preliminary analysis of clustering of galaxies luminous in the near- and mid-infrared as seen by seven various filters of the AKARI IRC instrument from 2 micrometers to 24 micrometers in the AKARI NEP-Deep field. We compare populations of galaxies detected in different filters and their clustering properties. We conclude that different AKARI filters allow to trace different populations composed mainly of star-forming galaxies located in different environments. In particular, the mid-infrared filters at redshift z approximately 0.8 and higher trace a population of strongly evolving galaxies located in massive haloes which might have ended as elliptical galaxies today.
