Project: The Role of Temperature in Regulating Herbivory and Algal Biomass in Upwelling Systems (Temperature and Herbivory)


Abstract

Increased standing macroalgal biomass in upwelling zones is generally assumed to be the result of higher nutrient flux due to upwelled waters. However, other factors can strongly impact macroalgal communities. For example, herbivory and temperature, via their effects on primary producers and the metabolic demands of consumers, can also influence macroalgal biomass and productivity, respectively. Although there are a fair number of studies looking at the interactive effects of herbivores and nut...

A data logger was attached by cable ties to the seafloor to continuously record environmental temperature in the Cerro Mundo study site, a shallow (10 meters deep) rocky reef off the west side of San Cristobal Island, Galapagos (0.87044°S, 89.58189°W). The logger was replaced every 9 months, before running out of battery, to keep a continuous record of temperature.
