Genetic population structure of Tectura paleacea: implications for the mechanisms regulating population structure in patchy coastal habitats.
Published 2011-04-01“…The seagrass limpet Tectura paleacea (Gastropoda; Patellogastropoda) belongs to a seagrass obligate lineage that has shifted from the Caribbean in the late Miocene, across the Isthmus of Panama prior to the closing of the Panamanian seaway, and then northward to its modern Baja California - Oregon distribution. …”

COCONUT GENETIC RESOURCES
Published 1992-12-01“…The origin of coconut was placed by Martius (1850) on the West Coast of Central America near the Isthmus of Panama. On the basis of evidences for the cultivation of coconut in Sri Lanka by about 300 BC. as well as the discovery of a fossil (Pliocene) Cocos in Newzealand (Hill, 1929) and in the deserts of Rajasthan (Kaul, 1951) the theory of Central American origin has been contested. …”

Cenozoic Methane-Seep Faunas of the Caribbean Region.
Published 2015-01-01“…We speculate that the increasingly oligotrophic conditions in the Caribbean Sea after the closure of the Isthmus of Panama in the Pliocene may have been unfavorable for such large lucinids because they are only facultative chemosymbiotic and need to derive a significant proportion of their nutrition from suspended organic matter.…”

What complete mitochondrial genomes tell us about the evolutionary history of the black soldier fly, Hermetia illucens
Published 2022-06-01“…We estimate the separation events of the different haplotypes at more than 2 million years for the oldest branches characterizing the ancestral split between present North American lineages and the other highly diverse south-central American clades, possibly the following radiation beyond the isthmus of Panama northwards. Our data confirm that this North American lineage ultimately gave birth to almost all commercial BSF stocks that participated in the worldwide BSF dissemination through farm escapements. …”

Lower Miocene stratigraphy along the Panama Canal and its bearing on the Central American Peninsula.

Morphological and molecular (28S rRNA) data of monogeneans (Platyhelminthes) infecting the gill lamellae of marine fishes in the Campeche Bank, southwest Gulf of Mexico
Published 2018-09-01“…As previously suggested, there are at least, two possibilities to explain that parasite distribution: differentiation of morphological features in these monogeneans have resulted in only slight to insignificant morphological changes developing over the extended period of 3.2 mya (when the Isthmus of Panama was closing) and/or speciation is only evident at molecular level.…”

Contrasting patterns of population structure of Bulwer’s petrel (Bulweria bulwerii) between oceans revealed by statistical phylogeography
Published 2023-02-01“…Conversely, divergence between the Central Pacific and Atlantic populations occurred within the last 200,000 years. While the Isthmus of Panama is important in restricting gene flow between oceans in Bulwer’s petrels, the deepest phylogeographic break is within the Pacific Ocean, where oceanographic barriers are key in driving and maintaining the remarkable structure found in this highly mobile seabird. …”

Whole genome assembly and annotation of the King Angelfish (Holacanthus passer) gives insight into the evolution of marine fishes of the Tropical Eastern Pacific
Published 2024-03-01“…Our demographic analysis suggests that population expansions of H. passer occurred prior to the last glacial maximum (LGM) and were more likely shaped by events associated with the closure of the Isthmus of Panama. This result is surprising, given that most rapid population expansions in both freshwater and marine organisms have been reported to occur globally after the LGM. …”
