Molecular identification of brachygenys and haemulon species (Perciformes: Haemulidae) from the brazilian coast
(2021-01-01)
The fishes of the Haemulidae family are currently allocated to 19 genera with a worldwide distribution in the tropical and subtropical waters of the world’s oceans. Brachygenys and Haemulon are important genera of reef ...
Species limits and morphometric and environmental variation within the South Andean and Patagonian Mulinum spinosum species-group (Apiaceae-Azorelloideae)
(Taylor & Francis, 2017-09)
Delimiting species is an important, but frequently difficult aspect of systematics that should be addressed using data from multiple sources. Here we combine morphometric analyses and environmental characteristics to delimit ...
Species delimitation of Planosiphon gracilis morphospecies (Scytosiphonaceae, Phaeophyceae) from Japan and the description of Pl. nakamurae sp. nov.
(International Phycological Society, 2020-03)
Molecular phylogenetic analyses based on mitochondrial cox1 and cox3 and chloroplast rbcL gene sequences revealed that the morphospecies of the brown alga Planosiphon gracilis (Scytosiphonaceae, Ectocarpales) from Japan ...
Molecular and morphological diversity in species of Kronichthys (Teleostei, Loricariidae) from Atlantic coastal rivers of Brazil
(Wiley-Blackwell, 2020-12-15)
The Neotropical catfish genus Kronichthys contains three species distributed along coastal rivers of southern and southeastern Brazil. Although phylogenetic hypotheses are available, the molecular and morphological diversity ...
One step beyond a broad molecular phylogenetic analysis: Species delimitation of Adenomera marmorata Steindachner, 1867 (Anura: Leptodactylidae)
(Public Library Science, 2020-02-21)
Taxonomists always have had intense discussions about how species should be delimited and recently many studies have used integrative approaches by combining molecular, morphological, and bioacoustic data. Although these ...
Biogeographic history and cryptic diversity of saxicolous Tropiduridae lizards endemic to the semiarid Caatinga
(BioMed Central, 2015-05-23)
Abstract
Background
Phylogeographic research has advanced in South America, with increasing efforts on taxa from the dry diagonal biomes. However, the diversification of ...
