AbstractOzone depletion by anthropogenic gases has increased the KEY WORDS atmospheric transmission of solar ultraviolet-B radiation (UV-B, 280–315 nm). Our understanding of the consequencences of enhanced UV-B levels on INTRODUCTION (/DOI/FULL/10.1146/ANNUREV.ECOLSYS.33.010802.150434#_I3) primary producers has grown dramatically over the past 20 years, but it has been hampered by how realistically experimental UV-B exposures mimic EXPERIMENTAL ozone-depletion scenarios. Overcoming these shortcomings will require PROTOCOLS sophisticated and creative approaches. Biological weighting functions and (/DOI/FULL/10.1146/ANNUREV.ECOLSYS.33.010802.150434#_I4) solar spectral irradiance estimates are critical in evaluating effects and require RESPONSES TO UV-B more attention. Whereas UV screening compounds in terrestrial and aquatic (/DOI/FULL/10.1146/ANNUREV.ECOLSYS.33.010802.150434#_I11) producers commonly increase with UV-B exposure, the implications, while CONCLUSIONS potentially far reaching, are unclear. Photosynthesis is more sensitive to UV-B (/DOI/FULL/10.1146/ANNUREV.ECOLSYS.33.010802.150434#_I17) in phytoplankton than in terrestrial plants, probably owing to less effective ACKNOWLEDGMENTS screening in phytoplankton. Productivity of terrestrial plants is usually (/DOI/FULL/10.1146/ANNUREV.ECOLSYS.33.010802.150434#_I18) unaffected by enhanced UV-B, although reduced growth has been observed LITERATURE CITED and may increase in magnitude over successive years. Aquatic productivity is (/DOI/FULL/10.1146/ANNUREV.ECOLSYS.33.010802.150434#_I19) often compromised by short-term exposures to enhanced UV-B, and long-term assessments are complicated by the dynamic nature of aquatic systems and by nonlinear responses. Recent work examining UV-B effects on multiple trophic levels suggests that outcomes will be diverse and difficult to predict. Such effects may lead to feedbacks on primary producers.
