Single-locus DNA barcoding and species delimitation of the sandfly subgenus Evandromyia (Aldamyia)
(Wiley Online Library, 2020)
Species delimitation reveals an underestimated diversity of Andean catfishes of the family Astroblepidae (Teleostei: Siluriformes)
(Soc Brasileira Ictiologia, 2020-01-01)
Catfishes of the family Astroblepidae form a group composed by 82 valid species of the genus Astroblepus inhabiting high-gradient streams and rivers throughout tropical portions of the Andean Cordillera. Little has been ...
New species in Gymnocalycium: a call for common sense
(David Hunt, 2014-03)
The proper delimitation of plant species is far away from being an issue restricted to debateamong professional botanists. Topics like teaching and communication about biodiversity,ecological and biogeographical research, ...
Sympatric and independently evolving lineages in the Thoropa miliaris – T. taophora species complex (Anura: Cycloramphidae)
(2022-01-01)
Species delimitation can be challenging and affected by subjectivity. Sibling lineages that occur in sympatry constitute good candidates for species delimitation regardless of the adopted species concept. The Thoropa ...
A multivariate morphometric delimitation of species boundaries in the South American genus Nicoraepoa (Poaceae: Pooideae: Poeae)
(Springer Wien, 2018-05)
A multivariate morphometric study of the genus Nicoraepoa was carried out to examine patterns of morphological variation among the species and to identify additional characters to allow a clearer delimitation among species. ...
Using integrative taxonomy and multispecies coalescent models for phylogeny reconstruction and species delimitation within the “Nastanthus–Gamocarpha” clade (Calyceraceae)
(Academic Press Inc Elsevier Science, 2019-01)
The Calyceraceae (47 spp.) is a small family of plants that is sister to the Asteraceae (∼ 25,000 spp.), one of the largest families of angiosperms. Most members of Calyceraceae are endemic to the Andes and Patagonia, ...
Molecular and morphological systematics of Dolabrifera Gray, 1847 (Mollusca: Gastropoda: Heterobranchia: Aplysiomorpha)
(Oxford University Press, 2018)
Molecular and morphological data from newly collected specimens and a review of the literature and type material indicate that the widespread tropical sea hare Dolabrifera dolabrifera is a species complex of five genetically ...
Speciation across mountains: Phylogenomics, species delimitation and taxonomy of the Liolaemus leopardinus clade (Squamata, Liolaemidae)
(Academic Press Inc., 2019)
Organisms rapidly diversifying across unstable environments such as mountain tops provide substantial challenges for resolving evolutionary histories and delimiting species. The Liolaemus leopardinus clade is a group of ...
Cathorops festae (boulenger 1898) (siluriformes; Ariidae), a valid species from Ecuador and Peru
(2016-09-22)
Over the past decade, the Sea Catfish (Ariidae) genus Cathorops has been the focus of a major taxonomic review, which has resulted in the revalidation of five synonymized nominal species, and the recognition of seven new ...
