2. Advances in the knowledge of the natural history of aquatic plants in the Neotropics
ABSTRACT Until the mid-XX century, little awareness on the ecological services or socio-environmental problems and benefits related to aquatic plants culminated in bottlenecks on their natural history, especially for the Neotropics. In this context, Acta Botanica Brasilica (ABB) organized this special issue to promote the advancement of knowledge on this eco

4. Mapping Biochemical Pathways in Maytenus ilicifolia (Celastraceae) through Integrated Proteomics and Histochemistry
Maytenus ilicifolia (Celastraceae) is a medicinal plant that is native to southern Brazil and is popularly known as “espinheira-santa”. From a biosynthesis perspective, this species accumulates quinonemethide triterpenes and sesquiterpene pyridine alkaloids as major secondary metabolites that exhibit interesting biological properties, with antitumoral an

5. FLORISTIC COMPOSITION AND DIVERSITY IN TERRA FIRME FOREST UNDER WATER STRESS IN THE AMAZON
ABSTRACT The studies on floristic composition are an aid in the understanding of the structure and dynamics of the plant communities, fundamental parameters for its management and conservation. Thus, the objective of this work was to evaluate the floristic composition, species richness, Shannon’s diversity and models of species abundance over a 10-year per

7. De la «sujétion», ou Crise de la sémiotique
Abstract Can semiotics theorise subjectivity? Since all communicated signs are framed by enunciation, inter-subjectivity is presupposed in semiosis, because it structures its deictic relations; but can subjectivity as such — which is a matter of cognitive psychology and phenomenology, both existential and formal — still be considered as an entity pertain

11. Concentration of Metals in Plant Litter Produced in Regions of Caatinga in Southwest Bahia, Brazil
Plant litter has several functions in a forest ecosystem. Studies about plant litter are of great importance to better understand and conserve ecological environments. The objective of this study was to investigate the concentration of metals (Fe, Co, Ca, Cu, Ni, Mg, Mn and Zn) in Caatinga plant litter in the southwest region of Bahia. Plant litter was colle

12. 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
