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. CONFIGURATIONS OF KNOWLEDGE-INTENSIVE ENTREPRENEURIAL ECOSYSTEMS
RESUMO O discurso dominante sobre os ecossistemas de empreendedorismo (EE) enfatiza o perfil de algumas localidades com histórico reconhecido de sucesso. Isso tem dificultado uma compreensão mais profunda dos mecanismos econômicos que moldam as tendências evolutivas na atividade empreendedora e como elas operam em lugares distintos. Nós propomos que ess

3. Fases psicológicas de gestantes com HIV: estudo qualitativo em hospital
Resumo Houve mudança de paradigma quanto ao prognóstico da infecção pelo vírus da imunodeficiência humana, passando da morte para problema crônico, mas ainda hoje a infecção implica revisão de vida da mulher que convive com a doença. O objetivo deste artigo foi apresentar as fases psicológicas pelas quais passam as gestantes após descobrirem a c

4. Run to the nest: A parody on the Iron Maiden song by Corotoca spp. (Coleoptera, Staphylinidae)
Abstract Rove beetles belonging to the genus Corotoca (Staphylinidae: Aleocharinae) are termitophiles exclusively found in nests of Constrictotermes (Isoptera: Termitidae). We observed the reproductive behavior of Corotoca melantho and C. fontesi during host (Constrictotermes cyphergaster) foraging events. The reproductive behaviors of both species are simil

5. Understanding Lies Based on Evolutionary Psychology: A Critical Review
Resumo O presente artigo tem por objetivo propor uma discussão teórica sobre o papel da mentira a partir da perspectiva da Psicologia Evolucionista, trazendo uma nova luz sobre os principais estudos realizados nessa área. Para tanto, este artigo aborda as filogenias e ontogenias da capacidade de mentir, ambas sugerindo que a ascensão da mentira como aç�

6. 2D magnetometric modeling of a basic-intermediate intrusion geometry: geophysical and geological approaches applied to the Limeira intrusion, Paraná Magmatic Province (SP, Brazil)
ABSTRACT: The Limeira Intrusion is an occurrence related to the Mesozoic continental flood basalts of Paraná Magmatic Province, cropping out at the eastern São Paulo state. It is made up of basic-intermediate rocks with a great diversity of structures, textures and modal compositions, related to specific evolutionary process in a magma chamber. Previous ge

7. Evolution of DNMT2 in drosophilids: Evidence for positive and purifying selection and insights into new protein (pathways) interactions
Abstract The DNA methyltransferase 2 (DNMT2) protein is the most conserved member of the DNA methyltransferase family. Nevertheless, its substrate specificity is still controversial and elusive. The genomic role and determinants of DNA methylation are poorly understood in invertebrates, and several mechanisms and associations are suggested. In Drosophila, th

8. Nuevo Constitucionalismo de la Biodiversidad vs. Neoconstitucionalismo del Riesgo
Abstract based on an "eco-systemic" democracy that seeks to preserve biodiversity through the recognition of the co-evolutionary link between nature and culture, the Andean Constitutionalism emerges as the expression of a counter-hegemonic constitutionalism committed to the construction of a new institutional framework through the inclusion of new participat

9. Unraveling the evolutionary scenario of the hobo element in populations of Drosophila melanogaster and D. simulans in South America using the TPE repeats as markers
Abstract Transposable elements (TEs) are nucleotide sequences found in most studied genomes. These elements are highly diversified and have a large variation in nucleotide structure and mechanisms of transposition. hobo is a member of class II, belonging to hAT superfamily, described inDrosophila melanogaster, and it presents in its Open Reading Frame, a rep

10. Challenging Mycobacterium tuberculosi s dormancy mechanisms and their immunodiagnostic potential
ABSTRACT Mycobacterium tuberculosis is the etiologic agent of tuberculosis, one of the world's greatest cause of morbidity and mortality due to infectious disease. Many evolutionary mechanisms have contributed to its high level of adaptation as a host pathogen. Prior to become dormant, a group of about 50 genes related to metabolic changes are transcribed by

11. X1X1X2X2/X1X2Y sex chromosome systems in the Neotropical Gymnotiformes electric fish of the genus Brachyhypopomus
Several types of sex chromosome systems have been recorded among Gymnotiformes, including male and female heterogamety, simple and multiple sex chromosomes, and different mechanisms of origin and evolution. The X1X1X2X2/X1X2Y systems identified in three species of this order are considered homoplasic for the group. In the genus Brachyhypopomus, only B. gaude

12. Update on cutaneous tuberculosis
Tuberculosis continues to draw special attention from health care professionals and society in general. Cutaneous tuberculosis is an infection caused by M. tuberculosis complex, M. bovis and bacillus Calmette-Guérin. Depending on individual immunity, environmental factors and the type of inoculum, it may present varied clinical and evolutionary aspects. Pat
