Residence times of consumers in subtidal areas on Isla Baltra, Gal?pagos during 2012 (GMR Trophic Cascades project)

Abstract:

Residence times of consumer species during a trophic cascade experiment conducted at 8- 10 m depth at Isla Baltra, Galápagos Islands from July 13 to July 19, 2012. Data represent counts of consumer species photographed with GoPro cameras at 1 second intervals during daylight hours in two adjacent areas of the bottom, named Baltra crest and Baltra gully. The consumers were photographed in the vicinity of treatments where sea urchins Lytechinus semituberculatus were enclosed in fences on substrates of consumable benthic algae. Data represent raw data of entrance and exit times from image analysis and the calculated difference.
