Species delimitation in sharpnose sharks (genus Rhizoprionodon) in the western Atlantic Ocean using mitochondrial DNA
(Springer, 2011-02-01)
Despite Springer's (1964) revision of the sharpnose sharks (genus Rhizoprionodon), the taxonomic definition and ranges of Rhizoprionodon in the western Atlantic Ocean remains problematic. In particular, the distinction ...

Evolutionary units delimitation and continental multilocus phylogeny of the hyperdiverse catfish genus Hypostomus
(2020-04-01)
With 149 currently recognized species, Hypostomus is one of the most species-rich catfish genera in the world, widely distributed over most of the Neotropical region. To clarify the evolutionary history of this genus, we ...
Delimiting species boundaries within the Bothriochloa saccharoides complex (Poaceae) through morphometric analysis
(Magnolia Press, 2013-03)
The Bothriochloa saccharoides complex is one of the most interesting groups within the genus Bothriochloa (Poaceae). The plants inhabit grasslands of tropical and subtropical regions from the Americas. Principal components ...
Extensive Cryptic Diversity Within the Physalaemus cuvieri-Physalaemus ephippifer Species Complex (Amphibia, Anura) Revealed by Cytogenetic, Mitochondrial, and Genomic Markers
(Frontiers Media Sa, 2019-08-14)
Previous cytogenetic and phylogenetic analyses showed a high variability in the frog taxa Physalaemus cuvieri and Physalaemus ephippifer and suggested the presence of undescribed diversity in this species complex. Here, ...
Phylogeography and species delimitation in convict cichlids (Cichlidae: Amatitlania): implications for taxonomy and Plio-Pleistocene evolutionary history in Central America
(Wiley-Blackwell, 2017-01-01)
We investigate phylogeographic patterns and delimit species boundaries within Amatitlania, a genus of Central American cichlid fishes. Phylogenetic analyses of mitochondrial DNA sequences from 318 individuals spanning the ...
Out of the deep: Cryptic speciation in a Neotropical gecko (Squamata, Phyllodactylidae) revealed by species delimitation methods
(Elsevier Inc.Maryland Heights, 2014-11)
Levels of biodiversity in the Neotropics are largely underestimated despite centuries of research interest in this region. This is particularly true for the Cerrado, the largest Neotropical savanna and a formally recognized ...
A test of color-based taxonomy in nudibranchs: Molecular phylogeny and species delimitation of the Felimida clenchi (Mollusca: Chromodorididae) species complex
(2016)
Traditionally, species identification in nudibranch gastropods relies heavily on body color pattern. The
Felimida clenchi species complex, a group of brightly colored Atlantic and Mediterranean species in the
family ...
