Structure of the Malpelo Ridge (Colombia) from seismic and gravity modelling [PDF]
Marine Geophysical Researches, 2006 Wide-angle and multichannel seismic data collected on the Malpelo Ridge provide an image of the deep structure of the ridge and new insights on its emplacement and tectonic history. The crustal structure of the Malpelo Ridge shows a 14 km thick asymmetric crustal root with a smooth transition to the oceanic basin southeastward, whereas the transition ...

Genetic population dynamics of the critically endangered scalloped hammerhead shark (Sphyrna lewini) in the Eastern Tropical Pacific. [PDF]
Ecol Evol, 2022 The scalloped hammerhead shark is a Critically Endangered (IUCN Red List), circumglobally distributed species in warm temperate and tropical seas. This species exhibits both periods of restricted movements as well a strong migratory propensity and is known to form iconic, large seasonal aggregations at offshore oceanic islands.

The land snails of Malpelo island, Colombia [PDF]
Journal of Molluscan Studies, 2012 The fauna of the volcanic island Malpelo located west of Colombia’s Pacific coast includes only two species of land snails. One is a new endemic species of the subulinid genus Ischnocion, with which Rectobelus, Microbeliscus and Nannobeliscus are provisionally synonymized.

Trophic inference in two sympatric sharks, Sphyrna lewini and Carcharhinus falciformis (Elasmobranchii: Carcharhiniformes), based on stable isotope analysis at Malpelo Island, Colombia [PDF]
Acta Ichthyologica Et Piscatoria, 2017 Background. Elasmobranchs can play important roles in marine communities. But, relatively little is known about their diet, and movement. Sphyrna lewini (Griffith et Smith, 1834) consumes fishes, cephalopods, rays, and crustaceans.

Coral connectivity between equatorial eastern Pacific marine protected areas: A biophysical modeling approach. [PDF]
PLoS ONE, 2018 There are many marine protected areas (MPAs) containing coral reef aggregations in the eastern Pacific region. However, the connectivity of corals between MPAs is still poorly known, especially in the Marine Conservation Corridor of the Eastern Tropical ...
