1. The taxonomic value of leaf anatomy for species Byrsonima: a difficult genus of Malpighiaceae Juss.
ABSTRACT We studied the leaf anatomy of 15 species of Byrsonima and a single species of Diacidia as an outgroup to test the relevance of leaf anatomical characters to the complicated taxonomy of this genus. We present complete anatomical descriptions for petioles and leaf blades, together with an anatomical matrix, dendrogram and an identification key for th

2. Karyotype characterization and evolution of chromosome number in Cactaceae with special emphasis on subfamily Cactoideae
ABSTRACT Cactaceae species are karyotypically well-known with x = 11 and chromosome number variation due mainly to polyploidization. However, both assumptions are based on descriptive observations without taking an evolutionary framework of Cactaceae into account. Aiming to confirm these hypotheses in an evolutionary context, we obtained chromosome numbers f

3. Megacities, migration and an evolutionary approach to bipolar disorder: a study of Sardinian immigrants in Latin America
Objective: To determine whether people with a Sardinian genetic background who live in the megacities of South America have a higher frequency of hypomania than residents of Sardinia. Methods: A community survey of Sardinian immigrants was carried out in four Brazilian metropoles (n=218) and Buenos Aires (n=306). The results were compared with those of a s

4. Hiding in plain sight: an evolutionary approach to the South American Zika outbreak and its future consequences
ABSTRACT Emerging Infectious Diseases (EID) pose a world-wide health and socio-economic threat. Accelerating climate change and globalization are exposing unforeseen ways that pathogens cope with their surroundings. The 2015 Zika virus (ZIKV) outbreak was an example of expansion into previously inaccessible fitness spaces, causing a sudden epidemic. Recent s

7. A ICONOGRAFIA LINEAR DA EVOLUÇÃO NA PERSPECTIVA DE DOCENTES QUE ATUAM NA EDUCAÇÃO BÁSICA
RESUMO: A marcha dos hominídeos tem influenciado fortemente a percepção das pessoas sobre a teoria evolutiva. Nesse artigo, analisamos se tal representação da evolução afeta a percepção dos educadores sobre Biologia e Ensino de Ciências. Através de uma pesquisa qualitativa, com a participação de professores de uma escola da periferia de São Pau

10. Mass and buckling criterion optimization of stiffened carbon/epoxy composite cylinder under external hydrostatic pressure
Abstract In this manuscript, stiffened carbon / epoxy composite cylinders under external hydrostatic pressure will be examined to minimize mass and maximize buckling pressure. The new approach proposed in this paper is single objective optimization of stiffened composite cylindrical shell under external pressure by genetic algorithm (GA) in order to obtain

11. Assessing population-level morphometric variation of the Mountain Mullet Agonostomus monticola (Teleostei: Mugilidae) across its Middle American distribution
ABSTRACT Population-level morphometric variation of the Mountain Mullet (Agonostomus monticola) was assessed in 419 adult specimens from 25 sample sites (river basins) across its Middle American distribution (Pacific and Atlantic-Caribbean drainages). This analysis was based on 36 standardized linear measurements and 19 landmarks on geometric morphometrics a

12. On the distinctive call of a threatened phenotype of Allobates femoralis (Anura: Aromobatidae) and its recognition by allopatric conspecific males
ABSTRACT The brilliant-thighed frog [Allobates femoralis (Boulenger, 1884)]; is distributed across the Amazon basin and aggregates several allopatric evolutionary lineages, some of which present variation in their advertisement calls. In 2009, an unregistered call phenotype was discovered in the region of Altamira and Vitória do Xingu, State of Pará, Brazi
