Investigating Environmental Factors and their effect on organismal DistributionHow to Cook a Penguin

Galapagos IslandsThe Galapagos Islands are a volcanic archipelago (island chain) located 500 miles off the coast of Ecuador on the equatorial boundaryThe Galapagos, made famous by Charles Darwin, compromises 18 main islands with Isabela and Fernandina being some of the largest and most western islands of the archipelagoThe unique positioning of the Galapagos falls between several important ocean current convergences that greatly affect the environment and habitat of the species that exist there

Galapagos PenguinsGalapagos penguins (Spheniscus mendiculus) are an endangered species of penguin living on the Galapagos islandsThey have adapted to the climate of the Galapagos due to unique environmental factors as well as slight behavior modifications that allow them to survive and reproduce in a relatively tropical climate90% of the population is restricted to the islands of Isabela and FernandinaPrimarily stay in the water during the day to feed and assume normal activity, while they inhabit the dry land at night seeking shelter in rocky crevices and outcrops along the coastlineEvolved adaptive behaviors of panting and shielding their feet with flippers to cool off and reduce heat loss on land when sun is still exposed

Humboldt and Cromwell CurrentsThe Humboldt or Peru current brings cold chilling waters from the south pole to the southern portion of the island chainThe Cromwell or Equatorial Undercurrent is an eastern traveling upwelling current that brings cold, nutrient-rich waters to the western islands of the Galapagos
