1. Can plant hybridization and polyploidy lead to pollinator shift?
ABSTRACT Events of both hybridization and polyploidy are capable of completely restructuring the genome, modifying phenotypic traits and affecting ecological interactions. For plants, these changes may affect floral traits that are important for interactions with pollinators, which could lead to shifts in pollinator behavior and taxa between hybrids/polyploi

2. Optimized protocol to isolate high quality genomic DNA from different tissues of a palm species
RESUMO A aplicação de técnicas moleculares para lidar com questões ecológicas e evolutivas requer DNA genômico de boa qualidade e quantidade. A qualidade do DNA isolado, no entanto, pode ser influenciada pelo tipo de tecido e pela maneira como a amostra foi conservada e manipulada. Portanto, personalizar protocolos para melhorar o isolamento do DNA e a

3. ESCRITA COLABORATIVA E INDIVIDUAL EM SALA DE AULA: UMA ANÁLISE DE TEXTOS ESCRITOS POR ALUNOS DO ENSINO FUNDAMENTAL
RESUMO A escrita colaborativa por díades em sala de aula é uma situação didática que coloca alunos dialogando para construir um único texto, ao contrário da escrita individual, em que normalmente se escreve sozinho e em silêncio. Filiado à Genética Textual, a partir de uma abordagem enunciativa, este trabalho desenvolveu um estudo comparativo com o

4. The use of microsatellite markers in Neotropical studies of wild birds: a literature review
ABSTRACT Despite extensive habitat fragmentation, the Neotropical region possesses 30% of the world´s bird species. Microsatellites have remained one of the most popular genetic markers and have been used in ecological and conservation studies since the 1990’s. We conducted a literature review comparing the number of papers published from January 1990 to

5. Exon-primed intron-crossing (EPIC) markers as a tool for ant phylogeography
Exon-primed intron-crossing (EPIC) markers as a tool for ant phylogeography. Due to their local abundance, diversity of adaptations and worldwide distribution, ants are a classic example of adaptive radiation. Despite this evolutionary and ecological importance, phylogeographical studies on ants have relied largely on mitochondrial markers. In this study we

6. Mantel test in population genetics
The comparison of genetic divergence or genetic distances, estimated by pairwise F ST and related statistics, with geographical distances by Mantel test is one of the most popular approaches to evaluate spatial processes driving population structure. There have been, however, recent criticisms and discussions on the statistical performance of the Mantel test

7. Diversidade, diferenciação e biogeografia de pequenos mamíferos não-voadores na Mata Atlântica ao norte do rio São Francisco Centro de Endemismo Pernambuco / Diversity, differentiation and biogeography of non-volant small mammals of the Atlantic Forest north of São Francisco river - Pernambuco Endemism Center
The Brazilian tropical rainforests (Amazon and Atlantic Forest) present high species diversity and are currently separated by a belt of open and dry vegetation. Part of this belt is occupied by the Caatinga, where are found the Brejos de Altitude, evidence of the historical connections between the Atlantic Forest and the Amazon. The Pernambuco Endemism Cente

8. La consolidación del programa adaptacionista
What we call today the adaptationist program did not play a prominent role in the Evolutionary Biology developed in the xixth century, and during the first four decades of the xxth century. Until 1940, only studies on animal colorations, fundamentally of insects, were oriented by an adaptationist agenda. During the period 1940-1970, with the developments of

9. Estudos moleculares em Hypochaeris catharinensis Cabrera (Asteraceae) utilizando marcadores AFLP
Hypochaeris catharinensis (Asteraceae) is endemic to south Brazil. In this work we used AFLP molecular marks (Amplified Fragment Length polymorphism) aiming to determine the genetic structure of H. catharinensis and to define its phylogenetic position within the South American group of the genus Hypochaeris. To define the phylogenetic position of H. catharin

10. Análise molecular de amostras fecais de uma população de veado-mateiro (Mazama americana) para a obtenção de informações genéticas e ecológicas / Molecular analysis of faecal samples of a red brocket deer (Mazama americana) population for obtaining genetic and ecological information
Mazama genus is composed by five species in Brazil. All of them are difficult to observe due to their evasive behaviors, what makes the captures and behavioral studies almost impossible. Thus, the use of non invasive methodologies is necessary to study the ecology and genetics of these species. The fecal DNA analysis is one of the most promising techniques f

11. Variability and genetic structure of Alabama argillacea (Hüeb.) (Lepidoptera: Noctuidae) populations in Brazil: Basis for managing resistance to Cry1Ac toxin in genetically modified cotton / Variabilidade e estrutura genética de populações de Alabama argillacea (Hüeb.) (Lepidoptera: Noctuidae) no Brasil: subsídios para o manejo da resistência à toxina Cry1Ac em algodão geneticamente modificado
Algodão geneticamente modificado que expressa a toxina Cry1Ac de Bacillus thuringiensis Berliner tem sido plantado no Brasil desde 2006. Entre as pragas-alvo da tecnologia, Alabama argillacea (Hüeb.) é uma espécie monófoga e apresenta alto potencial de risco de evolução da resistência. Para a implantação de um programa de manejo da resistência de

12. Isolamento e caracterização de locos de microssatélite para Neothraupis fasciata, (Emberizidae, Passeriformes, Aves),
Microsatellite molecular markers are small repeated sequences in tanden compound of 1 to 6 nucleotides. Widely used as genetic markers, the microsatellites have a particular attribute that is the high rates of mutation. These molecular markers or are widely used in conservation genetics, population genetics, forensic research, diagnosis of diseases, ecologic
