A review on effect of global climate change on seaweed and seagrass

Abstract

This study describes how global climate change influences the growth, production and reproduction of seaweed, seagrass and their associated ecosystems. All the data used in this study have been collected from numerous secondary sources. Seaweed survival, growth, and reproduction are varied with numerous environmental variables, including temperature, desiccation, wave heights, nutrient supply via upwelling and run-off, pH and carbon dioxide concentration itself. With the rising of sea levels, seagrass and seaweed habitats at any given location will experience reduced distribution and abundance. Either increases or decreases in salinity will impact seagrass and seaweed. The potential effects of increasing CO2 and the impacts of greater UV-B radiation will alter seagrass and seaweed photosynthesis and productivity. This review underscores the critical need of research on the direct effects of the various aspects of global climate change on seaweeds and seagrass.
