Although the conservation of tropical biodiversity depends on protected areas, there is still a very large 'gap' of knowledge on the flora of Brazilian reserves, especially in the Northeast region of Brazil. Field and herbarium surveys of the phanerogamic flora of the Ubajara National Park, located on the Brazilian Northeast, were made and analyses on phenology and dispersal syndromes were performed. 418 taxa (213 trees and shrubs, 100 terrestrial herbs, 68 climbing plants, 33 sub-shrubs, two epiphytes, one hemiparasite and one aquatic herb) were recorded. The most representative families were: Fabaceae, Malvaceae, Asteraceae, Rubiaceae and Euphorbiaceae. The annual flowering / fruiting peak hypothesis was not fully confirmed, therefore, the forest may be an important food resource for the fauna all year long (especially in the moister region). Zoochory was the predominant dispersal syndrome in the moister area, whereas, autochory and anemochory together, predominated in the drier area.

Por meio deste estudo, buscou-se identificar as ferramentas tecnológicas utilizadas no processo de ensino e aprendizagem frente à pandemia da COVID-19 em uma universidade pública do estado do Ceará. Para a coleta dados, foi realizada pesquisa exploratória com amostragem não-probabilística por conveniência, utilizando questionários semiestruturados através do Google forms.  Foram entrevistadas 126 pessoas, dos quais, 32 são professores e 96 estudantes. De acordo com as respostas dadas pelos estudantes, 86 % possuem Wi-Fi em casa. O restante utiliza internet de dados móveis ou da casa de vizinhos. Em relação às ferramentas utilizadas, 95% dos alunos utilizam Smartphones, enquanto 53% indicaram o notebook, 6% o computador e apenas 1% utiliza a TV. O Google meet foi apontado como o aplicativo mais utilizado nas aulas. Entre os professores, a maioria relatou que possuem Wi-Fi em casa e as principais ferramentas utilizadas são smartphones, notebooks, computadores e uma minoria relatou o uso de tablets. De acordo com as respostas dos professores, 73% enviam material para os alunos como forma de interação. 67% gravam as aulas e as enviam, enquanto 64% fazem videoconferência. A maior parte dos entrevistados, incluindo professores e alunos, mencionou que as aulas presenciais são mais efetivas no processo de ensino e aprendizagem.  Dessa forma, nota-se que, apesar dos esforços do corpo acadêmico para dar continuidade às atividades de ensino durante a crise de saúde, ainda é necessário muito avanço na instituição de ensino no que se refere à inserção de tecnologias nos processos educacionais.

Pseudofrenelopsis and Brachyphyllum are two conifers that were part of the Lower Cretaceous (Aptian) taphoflora of the Crato Formation, Araripe Basin, northeastern Brazil. The former genus includes, so far, P. capillata and indeterminate species, whilst the latter is mainly represented by B. obesum, the most common plant megafossil recovered from that stratigraphic unit. Here, the stem and leaf anatomy of Pseudofrenelopsis sp. and B. obesum specimens is revisited, including the first report of some epidermal and vascular traits for both taxa from the Crato Formation. Along with its paleoecological significance, the new data suggest the presence of more than one Pseudofrenelopsis species in the Aptian taphoflora of the Araripe Basin and further support the taxonomic placement of B. obesum within Araucariaceae.

Through this study, the objective was to contribute to the knowledge regarding floristic composition, classification and conservation status of the studied plant species as well as the dispersion syndromes of flora found in a disjoint Cerrado area ​in the Chapada do Araripe, Crato-CE. For the research development Rapid Survey method, applied in three walking lines (Line 1, Line 2 and Line 3) was adopted. Floriferous branches, fruits and seeds from species in the study area were collected in order to identify them and to characterize their diaspores, in view of fitting them into the corresponding dispersion syndromes. A total of 103 species were identified, the richest species taxa were: Fabaceae, Apocynaceae, Euphorbiaceae, Malpighiaceae and Myrtaceae. The most abundant species in the studied area were: Cordiera myrciifolia (“bola”) Miconia albicans (“Candeiro-de-pelo”), Caryocar coriaceum (pequi) and Copaifera langsdorffii (“pau d'oleo”). Three new occurrences were also recorded for the state of Ceará: Eriope tumidicaulis, Myrciaria cf. tenella and Stachytapheta cf. crassifolia. The most frequent dispersion syndrome was zoochoria, followed by anemocoria. Considering that most of the species occurring in the study area have their dispersion diaspores transported by a fauna element, the importance of these species for the maintenance of the observed floristic richness is evident.
