Using the extensive multi-wavelength data in the GOODS-North field, weconstruct and draw comparisons between samples of optical and near-IR selectedstar-forming and passively evolving galaxies at redshifts 1.4<z<2.6. We findoverlap at the 70-80% level in samples of z~2 star-forming galaxies selected bytheir optical (UGR) and near-IR (BzK) colors when subjected to common K-bandlimits. Deep Chandra data indicate a 25% AGN fraction among near-IR selectedobjects, much of which occurs among near-IR bright objects (K<20; Vega).Stacking the X-ray emission for the star-forming galaxies, we find the SFRdistributions of UGR, BzK, and J-K>2.3 galaxies (Distant Red Galaxies; DRGs)are very similar as a function of K, with K<20 galaxies having <SFR>~120Msun/yr, a factor of two to three higher than those with K>20.5. The absence ofX-ray emission from the reddest DRGs and BzK galaxies with z-K>3 indicates theymust have declining star formation histories to explain their red colors andlow SFRs. While the M/L ratio of passively-evolving galaxies may be larger onaverage, the Spitzer/IRAC data indicate that their inferred stellar masses donot exceed the range spanned by optically selected galaxies, suggesting thatthe disparity in current SFR may not indicate a fundamental difference betweenoptical and near-IR selected massive galaxies (M* > 10^11 Msun). We considerthe contribution of UGR, BzK, DRG, and submillimeter galaxies (SMGs) to theSFRD at z~2, taking into account sample overlap. The total SFRD in the interval1.4<z<2.6 of UGR and BzK galaxies to K=22, and DRGs to K=21 is ~ 0.10+/-0.02Msun/yr/Mpc^3. Optically-selected galaxies to R=25.5 and K=22 account for ~70%of this total. Of the radio-selected SMGs to S(850 micron)~4 mJy with redshifts1.4<z<2.6, >80% could be selected by the UGR, BzK, and/or DRG criteria.Comment: 22 pages, 20 figures, accepted to ApJ; change to Table
