Abstract

Data examining the effects of fertilizer addition on damselfish behavior from a before-after control impact (BACI) experiment conducted in Moorea, French Polynesia in order to understand the effects of nutrient pulse events on fish herbivory and agonism. The effects of treatments on behavior were assessed by video recording each territory with a GoPro Hero7 black for 20­–30 min immediately before applying treatments (“Day 0”) and 14 days post-treatment (“Day 14”). We assessed: 1) grazing by dams...

This dataset is part of a larger study of the coral reef ecosystem in Mo’orea, French Polynesia that examines mechanisms governing interactions between damselfish, corals, and turf algae. The different analyses from the broader study are listed here, with links to these associated data in the 'Related Datasets' section below.  

Analyses undertaken include:

  • Fertilizer impacts on damselfish behavior (this dataset of Damselfish behavior video)
  • Fertilizer impacts on biomass plus isotopic composition of algal turfs (Damselfish turf biomass dataset 950508)
  • Fertilizer impacts on coral predation and herbivory (Corallivory dataset 9xxxxxx, Herbivory dataset 9xxxxx)
  • Impacts of fertilizer and caging on coral and algal growth (Coral growth dataset 9xxxxx, Algal overgrowth dataset 9xxxxxx)
  • Coral-turf allelopathy (Turf extracts PAM dataset 949219, Coral-algal contact dataset 9xxxxxx)
  • Species composition of turf gardens (dataset 949552 + supplemental for Coral Reefs paper)
