Ultraviolet radiation and consumer effects on a field-grown intertidal macroalgal assemblage in Antarctica / Katharina Zacher, and 4 others.

Title: Ultraviolet radiation and consumer effects on a field-grown intertidal macroalgal assemblage in Antarctica / Katharina Zacher, and 4 others.
Author(s): Zacher, Katharina.
Date: 2007.
Publisher: Oxford: Blackwell Publishing
Abstract: Examines effects of ultraviolet radiation (UVR) and consumers on early successional stages of hard bottom macroalgal community of King George Island, South Shetland Islands, between November 2004 and March 2005. Observations were made of dry mass, species richness, diversity and composition of macroalgal assemblages developing on ceramic tiles. Consumers significantly suppressed green algal recruits and total algal biomass, but increased macroalgal richness and diversity. Both UVA and UVB radiation negatively affected macroalgal succession. UVR decreased density of Monostroma hariotii germlings in first 10 weeks of experiment, whereas density of red algal recruits was significantly depressed by UVR at end of study. After 106 days macroalgal diversity was significantly higher in UV-depleted than in UV-exposed assemblages. Species richness was significantly lower in UV treatments, and species composition differed significantly between UV-depleted and UV-exposed treatment. Results suggest that increase in UVB radiation due to stratospheric ozone depletion may affect zonation, composition and diversity of Antarctic intertidal seaweeds, altering trophic interactions in this system.
