Press versus pulse nutrient supply and species interactions mediate growth of coral reef macroalgae

Globally, ecosystems are experiencing dramatic alterations in the supply of resources, including nutrients. How the temporal regime (press versus pulse), independent of total resource supply, affects growth and species interactions of primary producers remains unexplored. Coral reefs experience anthropogenic modifications to nutrient regimes, making it critical to understand impacts on primary producers, such as macroalgae. In mesocosms, we examined how three macroalgae respond to the temporal pattern in nutrient regime (ambient, press, pulse) and species interactions (alone, pairwise, or all together) in terms of their individual growth and assemblage productivity. We found nutrient regime and species interactions influenced individual growth and total assemblage productivity. Press regimes promoted the highest productivity of total assemblages. We observed species interactions ranging from competitive to facilitative varied between macroalgal species and nutrient regimes. Ours is the ..., Please see the README document (\"README_Dataset-PressvPulseMacroalgae_v0.1.0.txt\") and the accompanying published article: Sura, S. A., Gehris, C. G., Liang, M. Y., Lim, A.
