1. Reproductive phenology of aquatic macrophytes in the Cerrado-Pantanal ecotone
ABSTRACT Studies of plant phenology have been performed predominantly with terrestrial species and rarely so with aquatic communities. Such plants are fundamental for the aquatic ecosystems, representing a valuable source of resources when they are scarce in terrestrial environments for the fauna. Studies of phenology help to understand the reproduction rhyt

2. Phenology and dispersal syndromes of woody species in deciduous forest fragments of the Pantanal in Mato Grosso do Sul State, Brazil
ABSTRACT We analyzed the phenological responses of shrub-tree species of lowland deciduous (LDF) and submontane deciduous (SFD) forests in the Pantanal, and assessed their relationships with climatic factors at the community level and with strategies for seed dispersal. Vegetative and reproductive phenophases of 50 tree-shrub species were monitored monthly (

3. What is on the menu for frugivorous birds in the Cerrado? Fruiting phenology and nutritional traits highlight the importance of habitat complementarity
ABSTRACT The relationship between plants and frugivorous animals is modulated by morphological and nutritional characteristics of fruits, as well as their seasonal availability across habitats. We evaluated fruiting phenology, fruit morphology and nutritional characteristics of 35 abundant plant species from 15 families associated with frugivorous birds from

4. PHENOLOGY OF Calotropis procera (Ait.) W.T. Aiton ACCESSIONS BASED ON MORPHOPHYSIOLOGICAL CHARACTERISTICS
RESUMO Objetivou-se com esta pesquisa avaliar a fenologia de acessos de C. procera com base em características morfofisiológicas. Foram coletadas sementes de 70 acessos de C. procera entre outubro de 2015 e janeiro de 2016, em áreas de ocorrência natural da espécie, na região Nordeste do Brasil. Atualmente esses acessos compõem a coleção de germopla

5. Physiological maturity of Physalis angulata L. seeds
RESUMO A determinação da maturidade fisiológica de sementes possibilita prever o momento mais adequado para a colheita, visando a obtenção de sementes com elevado potencial fisiológico. Physalis angulata (Solanaceae) possui potencial farmacológico e agroindustrial, todavia ainda há carência de informações quanto à sua fenologia reprodutiva. Nesse

9. Reproductive morphology and phenological aspects of one morphological variant of Hypnea pseudomusciformis (Gigartinales, Rhodophyta)
ABSTRACT Hypnea pseudomusciformis was recently described from South America, and has three morphological variants: “musciformis”, “nigrescens”, and “valentiae”. Information on the biology of these variants may help to explain this species’ wide morphological variation despite the absence of genetic divergence among variants. More morphological

10. Pollination biology of melittophilous legume tree species in the Atlantic Forest in Southeast Brazil
ABSTRACT This study describes the floral phenology and morphology, reproductive biology and pollinators for eight legume tree species, Schizolobium parahyba, Senna macranthera, and Senna multijuga (Caesalpinioideae), as well as Andira fraxinifolia, Lonchocarpus cultratus, Pterocarpus violaceus, Swartzia oblata, and S. simplex (Papilionoideae), in the Atlanti

11. Capitulum and floret phenology in Baccharis aliena (Asteraceae, Astereae)
Abstract Inflorescence and floral phenological studies are a source of valuable knowledge to interpret reproductive mechanisms and phylogenetic hypothesis in plants. We analyzed the morphology and functionality floret stages that are present in pistillate homogamous and functionally staminate heterogamous capitula of the dioecious species Baccharis aliena. P

12. Reproductive phenology differs between evergreen and deciduous species in a Northeast Brazilian savanna
ABSTRACT Evergreen (EG) and deciduous (DEC) species exhibit distinct strategies to overcome dry periods and achieve adequate water status for reproduction and growth. Such particularities may result in distinct reproductive strategies between these groups. Thus, we evaluated the phenology of EG and DEC groups, comparing and differentiating their reproductive
