1. The aquatic species Pontederia azurea and P. crassipes (Pontederiaceae) in the Pantanal, Brazil: evidence of how plant structure can simultaneously reflect phylogeny and ecology

ABSTRACT Hydric fluctuations in the Pantanal comprise annual dry and wet seasons that modify local diversity and plant morphology and anatomy. Widespread in this wetland are the sympatric Pontederia azurea and P. crassipes, which, although primarily aquatic, can also develop in non-flooded environments. This study undertook a comparative investigation of the

2. Toward a phylogenetic reclassification of the subfamily Ambavioideae (Annonaceae): establishment of a new subfamily and a new tribe

ABSTRACT A molecular phylogeny of the subfamily Ambavioideae (Annonaceae) was reconstructed using up to eight plastid DNA regions (matK, ndhF, and rbcL exons; trnL intron; atpB-rbcL, psbA-trnH, trnL-trnF, and trnS-trnG intergenic spacers). The results indicate that the subfamily is not monophyletic, with the monotypic genus Meiocarpidium resolved as the seco

3. ISOFLAVONOIDES DA TRIBO DALBERGIEAE: UMA CONTRIBUIÇÃO QUIMIOSSISTEMÁTICA PARA A SUBFAMÍLIA PAPILIONOIDEAE

Plants from Fabaceae family have several secondary metabolites and high biological potential. The subfamily Papilionoideae (Fabaceae) has 28 tribes, of which Dalbergieae comprises 49 genera and 1325 species. Isoflavonoids are chemotaxonomic markers of Papilionoideae and have important biological properties. This review describes the isoflavonoids and biologi

4. Application of Cervical Vestibular-Evoked Myogenic Potentials in Adults with Moderate to Profound Sensorineural Hearing Loss: A Preliminary Study

Abstract Introduction The cochlea and the vestibular receptors are closely related in terms of anatomy and phylogeny. Patients with moderate to profound sensorineural hearing loss (MPSHL) should have their vestibular organ functions tested. Objective To evaluate the incidence of vestibular abnormalities in patients with MPSHL and to study the correlation

5. Cultivable bacterial diversity associated with bromeliad roots from ironstone outcrops in central Brazil

Resumo Estudos sobre a diversidade bacteriana associada a plantas silvestres são raros, especialmente naqueles que crescem em associação com bromélias. No presente estudo, isolamos e identificamos bactérias epífitas e endofíticas das raízes das bromélias Dyckia excelsa, D. leptostachya e Deuterocohnia meziana ocorrentes nas “cangas” no Pantanal

RESUMO: O objetivo foi determinar a disseminação de perfis geneticamente semelhantes de Campylobacter em carcaças de frango e avaliar sua capacidade de produzir transcritos para os genes ciaB, dnaJ, p19 e sodB, antes e após o cultivo em células Caco-2. As cepas utilizadas foram isoladas de 420 amostras de carcaças de frango resfriadas e congeladas pron

7. [PROVISIONAL] Low cytomolecular diversification in the genus Stylosanthes Sw. (Papilionoideae, Leguminosae)

Abstract Stylosanthes (Papilionoideae, Leguminosae) is a predominantly neotropical genus with ~ 48 species that includes worldwide important forage species. This study presents the chromosome number and morphology of eight species of the genus Stylosanthes (S. acuminata, S. gracilis, S. grandifolia, S. guianensis, S. hippocampoides, S. pilosa, S. macrocephal

8. Detection of Diarrheagenic Escherichia coli in Bovine Meat in the Northern Region of Paraná State, Brazil

Abstract Ground bovine meat is commonly consumed by the population of Brazil. However, it constitutes an excellent medium for the multiplication of microorganisms due to available nutrients and handling practices prior to consumption. Here, we examined 100 samples of ground beef for the presence of diarrheagenic Escherichia coli (DEC) pathotypes by PCR, and

Abstract: Discoveries in Carnian-aged rocks are establishing a rich and diverse dinosaurian fauna at the so-called ‘dawn of the age of dinosaurs’ in the Late Triassic of Western Gondwana. Accordingly, Brazilian strata from the Candelária Sequence have contributed extensively to this trend. Here, we present a new dinosaurian specimen (CAPPA/UFSM 0200) fr

Abstract SPLs are plant-specific transcription factors that play important regulatory roles in plant growth and development. Systematic analysis of the SPL family has been performed in numerous plants, such as Arabidopsis, rice, and Populus. However, no comparative analysis has been performed across different species to examine evolutionary features. In this

ABSTRACT The Augochlora clade includes four genera: Augochlora Smith, Augochlorella Sandhouse, Ceratalictus Moure, and Pereirapis Moure. This is one of the richest and most widespread groups of Augochlorini bees. There are about 150 species, which occur from Argentina to Canada. The species of Augochlora clade are considered solitary to facultatively social,

Abstract The genus Spondias (family Anacardiaceae) comprises 19 taxa, ten of which occur in Neotropical regions. Spondias bahiensis has been suggested to be a hybrid, although initial evidence does not support this hypothesis. The aim of this study was to test the hypothesis of the hybrid origin of S. bahiensis using high-throughput sequencing with single nu
