Diversos repositórios de componentes têm sido propostos com o objetivo de potencializar o reuso de software. No entanto, as propostas atuais ainda adotam abordagens locais e centralizadas, que inibem o reuso em larga escala. Neste contexto, este artigo apresenta um serviço de repositório compartilhado e distribuído, que integra facilidades de controle de acesso, controle de versão e gerência de métricas de reuso. Como inovação, o repositório proposto pode ser explorado em abordagens de desenvolvimento distribuído, nas quais equipes remotas compartilham artefatos de software.
The forest ecosystems of the Amazonia biome are indispensable for climate regulation and service provision. Among them, the fluvial plains (ESFpf) stand out, due to their role in erosion control and water quality. However, the limited information available on this ecosystem is evident when compared to interfluvial plateaus (ESFpi). Thus, this study aimed to evaluate and compare the litter stock and water storage capacity in successional ecosystems in the Eastern Amazonia. The study ecosystems (ESFpf and ESFpi) are located in the municipality of Belém, Pará, in the region of the lower Guamá River. In each ecosystem, 12 permanent plots (100 m²) were installed, where in the periods of higher and lower rainfall, three subunits of litter samples were randomly collected. Water storage in the rainy season did not differ between ecosystems, while in the less rainy season ESFpf (245.91 ± 73.19%) was higher than ESFpi (182.31 ± 77.25%). For the litter stock, there was no influence of seasonality and in both periods the ESFpi averages were higher. Infer that due to the favorable conditions for the action of the edaphic fauna in the ESFpf, there was a reduction in the contact area of the litter, increasing the water storage capacity. The smaller stock found in the ESFpf allow to infer that there was an efficient cycling of nutrients, since these ecosystems are characterized by high litter deposition. Therefore, the results contribute to the understanding of the functional processes of the Amazon river plains ecosystems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
