Abstract

These data set contain results from trials used to measured predation rates by fish across time and sites showing a temperature gradient in San Cristobal, Galapagos. We used the squidpop protocol, an assay based in setting 25 stakes with squid bait for one hour in the reefs. Afterward we count how many bait were eaten to have a measure of predation rate. We did this on 15 sites. In 6 of this sites we conducted the assay every two months for 15 months. Measuring the relationship between temper...

Samples were collected using the squidpop protocol (Duffy et al., 2015). In each trial we set 20-25 stakes with squid attached to one end and the other end buried into the sand. We left the stakes for one hour. Afterward, we count how many bait were eaten to have an estimation of predation rates.
