ABSTRACT:The genetic diversity of a set of 21 hexaploid wheat germplasm from the National Agronomic Institute of Tunisia were investigated by applying 26 agro morphological traits and 10 wheat microsatellites molecular markers (Simple Sequence Repeat). The morphological variability was analyzed using the Principal Component Analysis (PCA) and the cluster analysis based on ward's method and square Euclidean distance. Eighteen microsatellites primer pairs were tested for all genotypes, among them 10 primers generated polymorphic and reproducible profiles. They revealed a total of 414 reducible bands among which 373 were polymorphic. The polymorphic information content (PIC) values per locus varied from 0,33 to 0,94 with an average of 0,72. Genetic similarity values between genotypes, calculated by the molecular derived data, were used to produce a dendrogram. The genotypes were clustered in four clear groups according to their origin, pedigree and in some cases to phenotypic characters similarities.

“…Below the nest tree, part of a dead howler monkey Alouatta belzebul (Linnaeus) was found, which was evidence that this nest was in an active cycle. In 2013, the Harpy Eagle pair started a new reproductive cycle, during which our monitoring was conducted until July 2015, including collection of feathers for genetic studies (Banhos et al, 2008) and prey remains for diet identification (AguiarSilva et al, 2014a). Since 2014, five other Harpy Eagle nesting trees were mapped near the low-and mid-Xingu River and were also a focus of this study.…”

In the Tapajos-Xingu interfluve, one of the largest birds of prey, the Harpy Eagle, is under intense anthropogenic pressure due to historical and recent reductions in forest cover. We studied prey availability and use by Harpy Eagle on six breeding territories on the low-and mid-Xingu River, between 2013 and 2015. We evaluated food resource availability using the environmental-surveys database from two methods: terrestrial surveys (RAPELD method) and fauna rescue/flushing before vegetation suppression for the Belo Monte Hydroelectric Complex construction. Harpy Eagle diet was identified by prey remains sampled around six nest trees. Eighteen species of mammals, birds and reptiles comprised the prey items. Most prey species were sloths, primates and porcupines, which have arboreal habits and are found in forested areas, but two species, hoatzin and iguana, are usually associated with riverine habitats. The proportion of prey from each species predated on the nest best studied was different from estimated availability (χ 2 = 54.23; df = 16; p < 0.001), however there was a positive correlation (r s = 0.7; p < 0.01) between prey species consumed and abundance available, where the predation was more on species more abundant. Continuous monitoring of the Harpy Eagle diet at these nests could evidence changes in the assemblage of prey species available for Harpy Eagles, due to changes in the seasonal flood pulse of the Xingu River to be caused by the operation of the hydroelectric dam, and changes in habitat features by forest reduction around breeding territories. We believe that it is important to consider the protection of remnants of forested areas in the landscape matrix surrounding the breeding territories to maintain the food resource availability and allow all pairs to successfully reproduce.Keywords: Behavioral ecology, Harpia harpyja, predator, mammals, Xingu River. Disponibilidade e consumo de presas por harpia no entorno de territórios de nidificação no rio Xingu, Amazônia Oriental BrasileiraResumo O interflúvio Tapajós-Xingu, um dos centros de endemismo da Amazônia, onde habita uma das mais poderosas aves de rapina, a harpia, é também alvo de intensa pressão antrópica com reduções históricas da cobertura florestal. Analisamos a disponibilidade de vertebrados e o consumo de presas por harpia em seis territórios de reprodução no Rio Xingu, entre 2013 e 2015. A disponibilidade de recursos alimentares foi baseada nos dados de amostragens por dois métodos: levantamentos terrestres pelo método RAPELD e resgate/afugentamento da fauna antes da supressão da vegetação para construção de infra-estrutura para o Complexo Hidrelétrico Belo Monte. As espécies de presas consumidas pela harpia foram identificadas a partir de vestígios coletados em seis ninhos. Dezoito espécies de mamíferos, aves e répteis compuseram a dieta no baixo e médio Rio Xingu, com maior proporção de preguiças, macacos e porcos-espinhos, incluindo duas espécies (Opisthocomus hoazin e Iguana iguana) associadas aos hábitats criados por rios.

“…Numerous reports suggest the usefulness of microsatellite markers for measuring the genetic variability in a wide taxonomic range (Banhos et al, 2008;Chan et al, 2008). These microsatellite markers have been used to assess the genetic diversity and relationships of date palm varieties in Tunisia (Zehdi et al, 2004), Sudan (Elshibli and Korpelainen, 2007), and Oman (Al-Ruqaishi et al, 2008).…”

ABSTRACT. The genetic diversity in the date palm germplasm of 59 female accessions representing 12 cultivars from different locations in Qatar was investigated using 14 loci of simple-sequence repeat (SSR) primers. A total of 94 alleles, with a mean of 6.7 alleles per locus, were scored. The number of alleles per locus varied from 3 (primer mPdCIR090) to 11 (primers mPdCIR010 and mPdCIR015). The amplified SSR band sizes ranged from 104 to 330 bp. The mean gene diversity was 0.66 and ranged from 0.39 (locus mPdCIRO93) to 0.86 (locus mPdCIR015), indicating that the Qatari date palm collection has a high degree of genetic diversity. The heterozygosity ranged from 0 (marker mPdCIR090) to 98% (marker mPdCIR010). Forty-four percent of the variability is explained at the inter-population level, while 56% of the variability is maintained within individuals. However, the loci mPdCIR044, mPdCIR057, mPdCIR090, and mPdCIR093 revealed that the total gene diversity is explained at the inter-population level. The Qatari populations Khalas, Shishi, Barhi, Hillali, Khnaizi, Gar, and Jabri showed significant differentiation compared to all other populations. The average fixation index was 0.24814, showing that about 24.81% of 1625 Genetic diversity of Qatari date palm ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 14 (1): 1624-1635 (2015) the genetic variation was present among populations, which correlated with analysis of molecular variance.
