Abstract

This dataset contains results from predation assays (squidpops) to determine fish predation intensity across a spatial and temporal gradient of temperature. Assays were conducted between June and November 2021 at six locations of rocky reefs along the Western coast of San Cristobal, the eastern Island of the Galapagos Archipelago.

Cite Dataset

The squidpop assays consiste of the deployment of 25 stakes with small pieces of squid on top for one hour by burying the stakes in sand on the edge of the reefs. After one hour, the number of baits eaten is quantified to estimate predation intensity. Trials were done in six localities during the months of July and November. The study sites were rocky reefs along the Western coast of San Cristobal, the eastern Island of the Galapagos Archipelago.
