25. Caracterizacion y analisis de la variabilidad genética de la granadilla (Passiflora ligularis juss.) en Colombia empleando marcadores microsatélites
Sweet passion fruit is the second economically important species of the genus Passiflora and Colombia is the largest producer in the world with 53,000 t/year. There are however, few studies on intraspecific diversity within the species that establish genetic relationships between individuals. The objective of this research was to explore the genetic variabil

26. Validation of a microsatellite panel for parentage testing of locally adapted and commercial goats in Brazil
Brazilian goats are generally kept in small herds and extensive rearing systems, mainly in the northeastern region of the country. Despite production improvement in recent years, the lack of pedigree control has affected genetic progress. This study aimed to validate a panel of 16 microsatellites for parentage testing in locally adapted and commercial goats

27. Genetic similarity among Tunisian cultivated olive estimated through SSR markers
Olive (Olea europaea L. subsp. europaea var. europaea) is one of the oldest fruit tree in the Mediterranean basin, and is cultivated for oil and canned fruit. Part of this interest is driven by the economic importance of olive oil which is increasing throughout the world due to its beneficial effect to human health. In Tunisia, olive has great socio-economic

28. Spatial and temporal population genetic variation and structure of Nothotsuga longibracteata (Pinaceae), a relic conifer species endemic to subtropical China
Nothotsuga longibracteata, a relic and endangered conifer species endemic to subtropical China, was studied for examining the spatial-temporal population genetic variation and structure to understand the historical biogeographical processes underlying the present geographical distribution. Ten populations were sampled over the entire natural range of the spe

29. Comparison of the effectiveness of microsatellites and SNP panels for genetic identification, traceability and assessment of parentage in an inbred Angus herd
During the last decade, microsatellites (short tandem repeats or STRs) have been successfully used for animal genetic identification, traceability and paternity, although in recent year single nucleotide polymorphisms (SNPs) have been increasingly used for this purpose. An efficient SNP identification system requires a marker set with enough power to identif

30. Molecular genetic diversity in populations of the stingless bee Plebeia remota: A case study
Genetic diversity is a major component of the biological diversity of an ecosystem. The survival of a population may be seriously threatened if its genetic diversity values are low. In this work, we measured the genetic diversity of the stingless bee Plebeia remota based on molecular data obtained by analyzing 15 microsatellite loci and sequencing two mitoch

31. Fine mapping and single nucleotide polymorphism effects estimation on pig chromosomes 1, 4, 7, 8, 17 and X
Fine mapping of quantitative trait loci (QTL) from previous linkage studies was performed on pig chromosomes 1, 4, 7, 8, 17, and X which were known to harbor QTL. Traits were divided into: growth performance, carcass, internal organs, cut yields, and meat quality. Fifty families were used of a F2 population produced by crossing local Brazilian Piau boars wit

32. Biologia reprodutiva de rainhas e machos de Tetragonisca angustula (Hymenoptera: Meliponini) / Reproductive biology of the queens and males of Tetragonisca angustula (Hymenoptera: Meliponini)
The stingless bees (Hymenoptera: Meliponini)present a haplodiploid sex determination system with complementary sex determination in a single locus. Such a system is a large genetic load for the group and thus the genetic diversity of male\ s aggregations near the nests is essential to minimize the chances of inbreeding. The interactions among the stingless b

33. Diversidade genética de Qualea grandiflora Mart estimada por microssatélites em quatro áreas de Cerrado do estado de São Paulo / Genetic diversity of Qualea grandiflora Mart estimated by microsatellites in four Cerrado areas of São Paulo
This study deals with the structure and genetic diversity of a species typical of the Brazilian Cerrado, Qualea grandiflora Mart (Vochysiaceae), present in different physiognomies of this biome. We developed eight microsatellite loci to analyze 420 samples of adult individuals from four populations distributed in the state of São Paulo, three of them in uni

34. Monitoramento genético da população Ex Situ da jacutinga (Aburria jacutinga, Aves, Cracidae) como subsídio para a conservação da espécie
Several critically endangered species and subspecies have been saved from extinction in recent years by Ex Situ conservation strategies. However, captive populations are generally small and exposed to the effects of genetic drift, inbreeding and founder effects. Thus, a major challenge for long-term reproduction of these animals is to reduce the loss of hete

35. Estudo de estrutura genética da espécie de Cactácea colunar Pilosocereus machrisii utilizando DNA microssatélite
Pilosocereus machrisii is a columnar cacti with natural fragmented distribution; restrict to campos rupestres vegetation patches or rocky outcrops on the Cerrado domain; in Central and eastern Brazil. These features makes P. machrisii an appropriate biological model for population genetic studies aiming to gather information on population structure; since sm

36. Análise populacional genética de Larus dominicanus através do uso de microssatélites / Population genetic analysis of Larus dominicanus using microsatellites
The changes in the coast that has been caused by human action has led to impacts on species associated with this environment. Larus dominicanus is a seabird species widely distributed throughout the Southern Hemisphere. The generalist feeding habits allow this species take advantage from human action, leading to population growth, which is also observed in o
