Environmental DNA (eDNA) reveals potential for interoceanic fish invasions across the Panama Canal
Ecology and Evolution, Volume 13, Issue 1, January 2023., 2023 The Panama Canal is a key region for biotic exchange as it connects the Pacific and Atlantic Oceans in Central America. In this study, we used two complementary methods (environmental DNA (eDNA) metabarcoding and gillnetting) to survey fish communities in this unique waterway.

Characterizing trophic ecology of the checkered puffer (Sphoeroides testudineus) [PDF]
Latin American Journal of Aquatic Research, 2017 ABSTRACT Sphoeroides testudineus (Linnaeus, 1758), is a common, widely distributed fish in coastal ecosystems. To better understand the trophic niche of S. testudineus, we collected individuals from tidal creeks on Abaco Island, The Bahamas, and employed stomach content and stable isotope analysis.
