1. Selection of Jatropha genotypes for bioenergy purpose: an approach with multitrait, multiharvest and effective population size
ABSTRACT Jatropha curcas L. is a perennial plant with great potential for biodiesel production. Thus, the aim of this study was to select J. curcas genotypes for bioenergy purpose considering multitrait, multiharvest and effective population size. To this end, a data set with 70 J. curcas families, obtained through controlled crosses, evaluated in a randomiz

2. The Effectiveness of Psycho-Educational and Cognitive-Behavioral Counseling on Female Sexual Dysfunction
Abstract Introduction Sexual function is a multidimensional phenomenon that is affected by many biological and psychological factors. Cognitive-behavioral sex therapies are among themost common nonpharmacological approaches to psychosexual problems. The purpose of the present study was to investigate the effectiveness of psychoeducational and cognitive-beh

4. Assessing genetic diversity and population structure in a Dipteryx alata germplasm collection utilizing microsatellite markers
Abstract Dipteryx alata Vogel (Leguminosae) is a native Neotropical tree with a wide distribution in the Brazilian Cerrado that is commonly known as the baru tree. The genetic diversity of 150 D. alata progeny from a germplasm collection was characterized using nine microsatellite markers. Genetic diversity analysis detected 50 alleles ranging from 2 to 14 a

5. Genetic diversity of long-established populations of Elaeis guineensis jacquin (Arecaceae)
Resumo Este trabalho objetivou estimar a diversidade genética de três populações de Elaeis guineensis no Estado do Rio Grande do Norte, bem como verificar a diminuição do tamanho efetivo da população. A população com maior polimorfismo foi a MAT (Mata), com 57 locos (72%), seguida pela RIA (Riacho), com 54 locos (68%), e HOR (Horta), com 34 locos

8. Genetic variability of tambaqui broodstocks in the Brazilian state of Pará
ABSTRACT The present study evaluated the genetic variability of the broodstocks of tambaqui hatcheries in the Brazilian state of Pará. Samples were obtained from the caudal fin of 110 broodstocks from one hatchery in each of four municipalities (Santarém, Peixe-Boi, Breu-Branco, and Ulianópolis), representing all the individuals of each hatchery stock.

10. Genetic Diversity and Structure of Calophyllum brasiliense Along the Santa Catarina Coast
ABSTRACT Population genetics studies can provide knowledge in support of conservation efforts for plant populations. We studied the genetic diversity and structure in nine populations of Calophyllum brasiliense from Santa Catarina state, Brazil, aiming to establish conservation strategies. Allozymic markers were used to genotype about 50 individuals from eac

11. Effective population size and genetic gain expected in a population of Coffea canephora
Abstract This work aimed to study the effective population size and genetic gain in a population of robusta coffee (Coffea canephora Pierre) and verify the possibility of using recurrent selection. The experiment comprised 25 treatments, consisting of 21 C. canephora progenies and four C. arabica (cultivars) grown in Brazil. The experimental design was a 5x5

12. Linkage disequilibrium and past effective population size in native Tunisian cattle
Abstract To carry out effective genome-wide association studies, information about linkage disequilibrium (LD) is essential. Here, we used medium-density SNP chips to provide estimates of LD in native Tunisian cattle. The two measures of LD that were used, mean r2 and D’, decreased from 0.26 to 0.05 and from 0.73 to 0.40, respectively, when the distance be
