Genetic differentiation in East African ethnicities and its relationship with endurance running success
(2022) [Artigo de periódico]Since the 1960s, East African athletes, mainly from Kenya and Ethiopia, have dominated long-distance running events in both the male and female categories. Further demographic studies have shown that two ethnic groups are ... -
Genetic diversity analysis of two Eucalyptus species using ISSR markers
(2020) [Artigo de periódico]Here, we deployed a genetic diversity analysis using ISSR markers in two Eucalyptus species, as a fundamental step toward breeding strategies. The selected species were Eucalyptus urophylla and Eucalyptus microcorys, both ... -
Genetic Diversity and Connectivity of Southern Right Whales (Eubalaena australis) Found in the Brazil and Chile–Peru Wintering Grounds and the South Georgia (Islas Georgias del Sur) Feeding Ground
(2020) [Artigo de periódico]As species recover from exploitation, continued assessments of connectivity and population structure are warranted to provide information for conservation and management. This is particularly true in species with high ... -
Genetic diversity and population structure of naturally rare Calibrachoa species with small distribution in southern Brazil
(2019) [Artigo de periódico]Calibrachoa is a South-American genus comprising 27 species, several considered endemic or rare; few were subjects in genetic studies. We attempted to generate new data about the phylogenetically related and rare species ... -
Genetic diversity and population structure of Vriesea reitzii (Bromeliaceae), a species from the Southern Brazilian Highlands
(2018) [Artigo de periódico]The Southern Brazilian Highlands are composed by a mosaic of Mixed Ombrophilous Forest (MOF) and grassland formations, an interesting landscape for the study of population structure. We analyzed the genetic diversity within ... -

(2014) [Artigo de periódico]This work aimed to evaluate the symbiotic compatibility and nodulation efficiency of rhizobia isolated from Desmodium incanum, Lotus corniculatus, L. subbiflorus, L. uliginosus and L. glaber plants by cross-inoculation. ... -
Genetic diversity in a Brazilian bovine herd based on four microsatellite loci
(2000) [Artigo de periódico]Microssatélites ou repetições curtas em tandem (STRs) são marcadores moleculares de relativa abundância no genoma e apresentam alto grau de polimorfismo, constituindo-se numa excelente ferramenta para a caracterização das ... -
Genetic diversity in Calibrachoa pygmaea (Solanaceae) a hawkmoth-pollinated nightshade from the Pampas
(2019) [Artigo de periódico]Calibrachoa pygmaea is a unique species of Calibrachoa, especially concerning its flower morphology and the environment where it occurs. The species is self-incompatible and is narrowly distributed in wet and flooded fields ... -
Genetic diversity of Echinococcus vogeli in the western Brazilian Amazon
(2019) [Artigo de periódico]Human polycystic echinococcosis is a parasitic infection caused by the larval stage of Echinococcus vogeli, which occurs in rural areas of Central and South America. Until now, little information on the genetic variability ... -
Genetic diversity of the Cryptococcus species complex suggests that Cryptococcus gattii deserves to have varieties
(2009) [Artigo de periódico]The Cryptococcus species complex contains two sibling taxa, Cryptococcus neoformans and Cryptococcus gattii. Both species are basidiomycetous yeasts and major pathogens of humans and other mammals. Genotyping methods have ... -
Genetic epidemiology of BRCA1- and BRCA2-associated cancer across Latin America
(2021) [Artigo de periódico]The prevalence and contribution of BRCA1/2 (BRCA) pathogenic variants (PVs) to the cancer burden in Latin America are not well understood. This study aims to address this disparity. BRCA analyses were performed on prospectively ... -
