Cryptic and invasive freshwater Galba snails
(The Malacological Society of London, 2020-08-19)
Thanks to the Early Career Research Grant and other grants, we developed an integrative approach combining morphological observations with molecular markers (microsatellites and DNA sequences for four genes) to analyze ...
Cryptic species in Iphisa elegans Gray, 1851 (Squamata: Gymnophthalmidae) revealed by hemipenial morphology and molecular data
(WILEY-BLACKWELLHOBOKEN, 2012)
Iphisa elegans Gray, 1851 is a ground-dwelling lizard widespread over Amazonia that displays a broadly conserved external morphology over its range. This wide geographical distribution and conservation of body form contrasts ...
The Phyllotis xanthopygus complex (Rodentia, Cricetidae) in central Andes, systematics and description of a new species
(Wiley Blackwell Publishing, Inc, 2021-11)
Phyllotis Waterhouse 1837 is one of the most studied genera of South American cricetid rodents. As currently understood, it includes 20 small to medium-sized species of predominantly rocky habitats. Among them, populations ...
DNA barcode discovers two cryptic species and two geographical radiations in the invasive drosophilid Zaprionus indianus
(Blackwell Publishing, 2008-05-01)
Comparing introduced to ancestral populations within a phylogeographical context is crucial in any study aiming to understand the ecological genetics of an invasive species. Zaprionus indianus is a cosmopolitan drosophilid ...
Comparative analysis of germ cells and DNA of the genus Amblyomma: adding new data on Amblyomma maculatum and Amblyomma ovale species (Acari: Ixodidae)
(2017-11-01)
Among tick species, members of the subfamily Amblyomminae have received special attention, since they serve as vectors for pathogens such as Rickettsia spp. and display cryptic species complexes that make their taxonomical ...
Designation of a neotype for mazama americana (Artiodactyla, cervidae) reveals a cryptic new complex of brocket deer species
(2020-01-01)
Mazama americana (red brocket deer) is the genus-type species (first species described for this genus) and the basis for the identity of other Mazama species. Mazama americana is one of the most abundant and widely distributed ...
Isoenzimatic analysis of four Anopheles (Kerteszia) cruzii (Diptera: Culicidae) populations of Brazil
(Fundação Oswaldo Cruz. Instituto Oswaldo Cruz., 2020)
Ecological divergence and synchronous Pleistocene diversification in the widespread South American butter frog complex
(2022-04-01)
Phylogeographic studies primarily focus on the major role of landscape topography in driving lineage diversification. However, populational phylogeographic breaks may also occur as a result of either niche conservatism or ...
Molecular and cytogenetic analyses of cryptic species within the Synbranchus marmoratus Bloch, 1795 (Synbranchiformes: Synbranchidae) grouping: Species delimitations, Karyotypic evolution and intraspecific diversification
(2014-01-01)
The fish species Synbranchus marmoratus has been reported to exist as a species complex due to high intraspecific karyotypic variability in spite of the difficulty or impossibility to distinguish them using morphological ...
Reproductive compatibility among Mexican populations of Anastrepha obliqua : theoretical and management implications
(Wiley Blackwell Publishing, Inc, 2018-03)
The fraterculus species group, composed of 34 species in the genus Anastrepha(Diptera: Tephritidae), includes the fraterculus cryptic species complex formed by eight reproductively isolated morphotypes. A previous study ...
