Genetic Diversity of Giardia duodenalis: Multilocus Genotyping Reveals Zoonotic Potential between Clinical and Environmental Sources in a Metropolitan Region of Brazil
The high degree of genetic diversity in the isolates obtained from both clinical and environmental samples suggests that multiple sources of infection are likely responsible for the detected contamination events and indicates that there is a notable risk of human infection caused by Giardia in this region.

Genetic structure of traditional varieties of bitter manioc in three soils in Central Amazonia
The first time that genetic divergence of bitter manioc varieties in cultivation in different Amazonian soils in a small geographic area is reported, suggesting important genetic structuring among varieties grown in the floodplain and upland soils (ADE and Oxisols). Expand
Population Genetic Structure of Two Columnar Cacti with a Patchy Distribution in Eastern Brazil
The genetic variability and population genetic structure of six populations of Praecereus euchlorus and PilosocereUS machrisii were investigated and favored historical fragmentation as the mechanism responsible for the patchy distribution of these two species. Expand
Permanent Genetic Resources added to Molecular Ecology Resources Database 1 October 2009–30 November 2009
The addition of 411 microsatellite marker loci and 15 pairs of Single Nucleotide Polymorphism (SNP) sequencing primers to the Molecular Ecology Resources Database are documents. Expand
The genetic structure and mating system of Acrocomia aculeata (Arecaceae)
There is every indication that A. aculeata bears a mixed reproductive system, with a predominance of outcrossing, and future conservation strategies and germplasm collecting should be focussed on sampling and preserving individuals from different clusters. Expand
Genetic Structure and Gene Flow Among Brazilian Populations of Heliothis virescens (Lepidoptera: Noctuidae)
Host plant association, crop growing season, and geographic origin were not responsible for the genetic structuring among Brazilian populations of H. virescens and other factors, such as demographic history and seasonal variability of intrapopulation genetic variation, were suggested to be molding the current pattern of genetic variability distribution. Expand
Genetic diversity in Atlantic Forest trees: fragmentation effects on Astronium graveolens (Anacardiaceae) and Metrodorea nigra (Rutaceae), species with distinct seed dispersal strategies
The results indicate that the depletion of forest land and the deteriorating condition of the remaining fragments of forest may reduce the level of endogamous breeding in wind-dispersed species. Expand
Species delimitation of Cattleya coccinea and C. mantiqueirae (Orchidaceae): insights from phylogenetic and population genetics analyses
The high-altitude Southeastern Brazilian Cattleya coccinea clade includes two taxonomically challenging species, Cattleya coccinea and Cattleya mantiqueirae, the latter considered restricted to theExpand
Genetic and morphological diagnosis and description of two cryptic species of flower head-infesting Tephritidae (Diptera)
The genetic identities and diversity of the dark and light morphs supported the hypothesis of cryptic species and a detailed morphological analysis revealed consistent differences in the male and female terminalia of the two morphs. Expand
Permanent Genetic Resources added to Molecular Ecology Resources Database 1 October 2011 – 30 November 2011
This article documents the addition of 139 microsatellite marker loci and 90 pairs of single‐nucleotide polymorphism sequencing primers to the Molecular Ecology Resources Database. Loci wereExpand
