J. A. F. Diniz-Filho, Diniz, J. V. B. P. L., Telles, M. P. C., Diniz-Filho, J. A. F., Diniz, J. V. B. P. L., Telles, M. P. C., Diniz-Filho, J. A. F., Diniz, J. V. B. P. L., and Telles, M. P. C., Exhaustive search for conservation networks of populations representing genetic diversity, vol. 15, p. -, 2016.

Conservation strategies routinely use optimization methods to identify the smallest number of units required to represent a set of features that need to be conserved, including biomes, species, and populations. In this study, we provide R scripts to facilitate exhaustive search for solutions that represent all of the alleles in networks with the smallest possible number of populations.

Intraspecific differentiation of Hancornia speciosa revealed by simple sequence repeat and random amplified polymorphic DNA markers

C. A. Nogueira, Stafuzza, N. B., Ribeiro, T. P., Prado, A. D. L., Menezes, I. P. P., Peixoto, N., Gonçalves, P. J., and Almeida, L. M., Intraspecific differentiation of Hancornia speciosa revealed by simple sequence repeat and random amplified polymorphic DNA markers, vol. 14, pp. 15996-16005, 2015.

Hancornia speciosa, popularly known as mangabeira, is a fruit tree native to the Brazilian Cerrado that shows great economic potential, due to its multiple uses. Intraspecific classification of this species is difficult because it shows high morphological diversity. An early study of the species reported that there are six botanic varieties that differ morphologically mainly in the shapes of their leaves and flowers.

Development of microsatellite markers for Hancornia speciosa Gomes (Apocynaceae)

A. J. L. Rodrigues, Yamaguishi, A. T., Chaves, L. J., Coelho, A. S. G., Lima, J. S., and Telles, M. P. C., Development of microsatellite markers for Hancornia speciosa Gomes (Apocynaceae), vol. 14, pp. 7274-7278, 2015.

Herein, we describe 34 microsatellite loci developed using an enrichment genomic library for the tree species Hancornia speciosa Gomes (Apocynaceae). Thirty-five individuals were genotyped using 34 primers to analyze the polymorphisms at each locus. The number of alleles per locus ranged from 4 to 20. The average number of alleles was 8.11, and the expected heterozygosity ranged from 0.62 to 0.94. These microsatellite primers will be useful in population genetics studies for this species.

Population genetic structure of Attalea vitrivir Zona (Arecaceae) in fragmented areas of southeast Brazil

R. R. M. Santos, Cavallari, M. M., Pimenta, M. A. S., Abreu, A. G., Costa, M. R., and Guedes, M. L., Population genetic structure of Attalea vitrivir Zona (Arecaceae) in fragmented areas of southeast Brazil, vol. 14, pp. 6472-6481, 2015.

Attalea vitrivir Zona (synonym Orbignya oleifera) is one of the six species of Arecaceae known as “babassu”. This species is used to make cosmetics, food, and detergents due to the high concentration of oil in the seeds. It is found only in fragmented areas of southern Bahia State and northern Minas Gerais State, southeast Brazil, and this fragmentation has affected both its ecological and genetic characteristics. We evaluated the genetic diversity and population genetic structure of A.

Isolation of high quality and polysaccharide-free DNA from leaves of Dimorphandra mollis (Leguminosae), a tree from the Brazilian Cerrado

H. A. V. Souza, Muller, L. A. C., Brandão, R. L., and Lovato, M. B., Isolation of high quality and polysaccharide-free DNA from leaves of Dimorphandra mollis (Leguminosae), a tree from the Brazilian Cerrado, vol. 11, pp. 756-764, 2012.

Dimorphandra mollis (Leguminosae), known as faveiro and fava d’anta, is a tree that is widely distributed throughout the Brazilian Cerrado (a savanna-like biome). This species is economically valuable and has been extensively exploited because its fruits contain the flavonoid rutin, which is used to produce medications for human circulatory diseases. Knowledge about its genetic diversity is needed to guide decisions about the conservation and rational use of this species in order to maintain its diversity.

Geographic shifts in climatically suitable areas and loss of genetic variability in Dipteryx alata (“Baru” Tree; Fabaceae)

J. A. F. Diniz-Filho, Collevatti, R. G., Chaves, L. J., Soares, T. N., Nabout, J. C., Rangel, T. F., Melo, D. B., Lima, J. S., and Telles, M. P. C., Geographic shifts in climatically suitable areas and loss of genetic variability in Dipteryx alata (“Baru” Tree; Fabaceae), vol. 11, pp. 1618-1626, 2012.

Many species are expected to suffer strong shifts in their geographic ranges due to climate changes in the next 50 years, with severe consequences for biodiversity patterns and population structure. We used here an ensemble forecast approach for obtaining species’ range in which multiple species distribution models and climatic models were combined to model loss of genetic variability in Baru, Dipteryx alata (Fabaceae), an economically important Neotropical tree native to the Cerrado of Brazil.

Isolation and characterization of 10 microsatellite loci for Pallas’ long-tongued bat Glossophaga soricina (Phyllostomidae)

M. Oprea, Peixoto, F. P., Resende, L. V., Collevatti, R. G., and Telles, M. P. C., Isolation and characterization of 10 microsatellite loci for Pallas’ long-tongued bat Glossophaga soricina (Phyllostomidae), vol. 11. pp. 3518-3521, 2012.

Glossophaga soricina is a widespread Neotropical nectarivorous bat. We characterized 10 microsatellite loci isolated from a shotgun genomic library. We analyzed tissues from wing membrane of 67 individuals collected from two populations of Central Brazil (Brasília and Alto Paraíso). The number of alleles per locus ranged from 2 to 20, and the observed and expected heterozygosities ranged from 0.015 to 0.666 and from 0.016 to 0.915, respectively.

Genetic diversity of gabiroba based on random amplified polymorphic DNA markers and morphological characteristics

E. S. de Assis, Reis, E. Fdos, Pinto, J. F. N., Contim, L. A. S., and Dias, L. A. S., Genetic diversity of gabiroba based on random amplified polymorphic DNA markers and morphological characteristics, vol. 12, pp. 3500-3509, 2013.

The fragmentation of the original vegetation of the Cerrado biome, caused by the expansion of agricultural areas, mainly in central-west Brazil, calls for an assessment of the native population of this vegetation, especially of the species of interest for domestication and sustainable use. The purpose of this study was to characterize the genetic diversity of 140 gabiroba mother plants (Campomanesia spp) and their progenies from 17 locations in Goiás.

Development and characterization of new microsatellites for Eugenia dysenterica DC (Myrtaceae)

M. P. C. Telles, Silva, J. B., Resende, L. V., Vianello, R. P., Chaves, L. J., Soares, T. N., and Collevatti, R. G., Development and characterization of new microsatellites for Eugenia dysenterica DC (Myrtaceae), vol. 12, pp. 3124-3127, 2013.

Microsatellite markers were developed for population genetic analyses of the Neotropical tree Eugenia dysenterica DC (Myrtaceae), after construction of a shotgun genomic library for microsatellite discovery. Nine primers were designed, of which 5 yielded amplified product. These primers were polymorphic for 97 individuals collected in 3 distinct localities. The number of alleles per locus (primer) ranged from 3 to 11 and expected heterozygosities varied from 0.309 to 0.884.

Kin structure and parallel dispersal in the black-and-gold howler monkey Alouatta caraya (Platyrrhini, Atelidae)

R. G. Collevatti, Souza-Neto, A. C., Silva-Jr., N. J., and Telles, M. P. C., Kin structure and parallel dispersal in the black-and-gold howler monkey Alouatta caraya (Platyrrhini, Atelidae), vol. 12, pp. 6018-6031, 2013.

We here investigated the kin structure and pattern of dispersal in the black-and-gold howler monkey (Alouatta caraya, Platyrrhini, Atelidae) based on genotype differences at nine microsatellite loci of 48 individuals from eight social groups along the riparian forest of the Tocantins River, Brazil. The genetic diversity (HE = 0.647) was similar to or higher than previously reported values in other Alouatta species.
