Studies comparing various streams are scarce in tropical insular systems and inexistent in Colombia. In order to understand the spatial patterns of macroinvertebrates in tropical insular streams, and the environmental drivers of such patterns, we tested for patterns among streams but using a nested sampling design from streams to microhabitats in ...

Radiometric ages of the Gorgona Island (Colombia) komatiitic ophiolite

open access: yes, 1982
A preliminary attempt to date the Gorgona Island komatiitic ophiolite with K-Ar has been made. Three gabbros give ages ranging from 86.2 ± 8.5 to 66.7 ± 8.0 m.y. which places the ophiolite in the Senonian (Upper Cretaceous).
