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 ...
Body size and genetic variation in the White-tipped Plantcutter (Phytotoma rutila: Cotingidae) suggest ecological divergence across the Chaco–Andes dry forest belt
(Springer, 2019-09)
Dry forests characterize many of the biomes of southern South America and the Andes, such as the Chaco and the inter-Andean valley forests, which form a continuous belt (Chaco–Andes dry forest belt). Some of the taxa that ...
Detection of natural hybridization and delimitation of two closely related operational taxonomic units of the Astyanax fasciatus (Teleostei: Characidae) complex through integrative approaches
(Oxford Univ Press, 2020-03-01)
Astyanax is a species-rich, non-monophyletic genus composed of several supraspecific taxa that are poorly delimited. The Astyanax fasciatus complex is one of these taxa and shows high taxonomic complexity. To elucidate the ...
Experimental infection of the rabbit tick, Haemaphysalis leporispalustris, with the bacterium Rickettsia rickettsii, and comparative biology of infected and uninfected tick lineages
(SPRINGER, 2009)
The present study consisted of two experiments that evaluated experimental infections of Haemaphysalis leporispalustris ticks by a Brazilian strain of Rickettsia rickettsii, and their effect on tick biology. In experiment ...
Direct molecular profiling of minicircle signatures and lineages of Trypanosoma cruzi bloodstream populations causing congenital Chagas disease
(Elsevier, 2007-10)
Congenital transmission of Trypanosoma cruzi may occur in some or all the gestations from a T. cruzi-infected mother. Variable rates of congenital transmission have been reported in different geographical areas where ...
How many species of Siphonaria pectinata (Gastropoda: Heterobranchia) are there?
(London, UK, 2015)
Siphonaria pectinata (Linnaeus, 1758) has been considered a widespread species with Amphiatlantic distribution
or a case of cryptic taxonomy where sibling species exist. We undertook molecular evaluation
of 66 specimens ...
