O presente estudo trata-se de um ensaio teorico que tem como objetivo apresentar um levantamento das diferentes atividades de herbarios de diferentes regioes do Brasil identificando suas acoes enquanto espacos formais e nao formais de educacao. A partir das analises realizadas, foi possivel identificar que herbarios podem apresentar-se de maneira fluida, podendo ser considerados espacos formais e nao formais de acordo com suas atividades executadas, permitindo acesso ao conhecimento cientifico tanto a um publico academico quanto leigo. Os herbarios podem contribuir para diminuir o abismo entre a Universidade enquanto espaco formal e a sociedade, passando a ressignificar espacos e atuar tambem como espacos nao formais de ensino, aliados na democratizacao do acesso aos conhecimentos sobre botânica para garantir a conservacao ...

Um evento chave no desenvolvimento de areas vegetais e a sindrome de dispersao de sementes, que consiste na ligacao entre a ultima fase reprodutiva da planta e a primeira fase do recrutamento de um novo individuo. Diante disso, o estudo objetivou classificar as sindromes de dispersao e destacar os aspectos ecologicos de diasporos para compreender a dinâmica que compoe a diversidade vegetal em dunas costeiras do litoral maranhense. O levantamento foi realizado ao longo das dunas na praia de Sao Marcos, municipio de Sao Luis, Maranhao. Mensalmente foram coletadas as plantas lenhosas em frutificacao, entre setembro de 2017 e janeiro de 2019. O material foi armazenado no Laboratorio de Estudos Botânicos (LEB). O processo de armazenamento ocorreu em duas etapas: os frutos secos em sacos plasticos com naftalina e os carnosos em potes com alcool ...

The identification of situations faced by academic community regarding generation of waste is essential to the elaboration of programs, projects, systems and policies for sustainable management of generated waste. This study aimed to understand how aware of this issue is academic community of the University City, Federal University of Maranhao (UFMA), through a profile of the production of solid waste and its impacts on the environment. The methodology was based on the application of 509 questionnaires during the year 2011 in four different campuses centers, including 33 undergraduate and graduate departments from various fields, and six administrative centers. The questionnaires consisted of questions about recycling policies and waste sorting. According to our results, 67.97 % of respondents know the 3Rs (reduce, reuse and recycle) and 92.32 % said they would partic...

In this work, we present the phenology of 19 woody species of coastal dunes located in the eastern end of the Amazon coast. We evaluate the phenological aspects of the community and their relationship with climatic factors (photoperiod, precipitation, and temperature). For this evaluation, 19 woody species with a diameter at soil height (DBH) > 3 cm and whole crown visible were selected. Information on leaf abscission, new leaves, flowering, and fruiting was collected fortnightly. The activity and intensity of each phenophase were estimated according to the Fournier index. Circular statistic was employed to determine the mean dates for the start and peak of the phenophases, and the percentage of activity and intensity for each phenophase. Multiple linear regression analysis was applied to investigate the relationships between phenophases and climatic variables. Additionally, leaf habits and pollination and dispersion syndromes were defined for each species. The results reveal that the species evaluated did not show seasonally defined behavior, nor were they related to the climatic factors evaluated. Most species showed evergreen leaf habit (83.4%), melittophilly as the primary pollination syndrome (78.9%), and zoochoric dispersal (84.22%). Although it does not present a seasonally defined behavior, nor is it related to the climatic factors evaluated, the dry season presented the highest percentages for all phenophases, which may indicate that other factors associated with the dry period may influence the trigger off the phenophases. The information collected expands the knowledge about the functioning of this ecosystem and reinforces the need for more ecological studies and reduced impact management measures, aiming at coastal vegetation conservation.
