The measurement of the Star Formation Rate density of the Universe is ofprime importance in understanding the formation and evolution of galaxies. The[OII]3727 emission line flux, easy to measure up to z~1.4 within deep redshiftsurveys in the optical and up to z~5.4 in the near infrared, offers a reliablemeans of characterizing the star formation properties of high-z objects. Inorder to provide the high-z studies with a local reference, we have measuredtotal [OII]3727 fluxes for the well analyzed local sample of star-forminggalaxies from the Universidad Complutense de Madrid Survey. This data is usedto derive the [OII]3727 luminosity function for local star-forming galaxies.When compared with similar luminosity densities published for redshift up toz~1, the overall evolution already observed in the star formation activity ofthe Universe is confirmed.Comment: 8 pages, 2 postscript figures, published in ApJ
