Temporal pattern of foraging and microhabitat use by Galápagos marine iguanas, Amblyrhynchus cristatus

  title={Temporal pattern of foraging and microhabitat use by Gal{\'a}pagos marine iguanas, Amblyrhynchus cristatus},
  author={William A Buttemer and William R. Dawson},
We observed a colony of marine iguanas (Amblyrhynchus cristatus) on Isla Fernandina, Galápagos, Ecuador, while measuring local micrometeorological and tidal conditions. We found size-related differences in foraging mode, with smaller iguanas feeding intertidally during daytime low tides and larger iguanas feeding subtidally. Despite having greater opportunity, subtidal foragers did not time their foraging bouts or exploit their environment in ways that optimized their period at high body… CONTINUE READING
