Data Symbion Environmental Intelligence: da gênese a reestruturação

One of the goals of the decade for the United Nations (UN) encompasses the prevention and conservation of the oceans and seas. In this way, the Data Symbion project was initially proposed, aiming at organizing and storing data related to marine biomes. With that in mind, this article presents the restructuring of this project, considering the use of data mining techniques, thus proposing the Data Symbion Environmental Intelligence. The article shows the development at system levels, its usage policies, data and user profiles. Currently the zero level of Data Symbion EI is available to any internet user.Uno de los objetivos de la década para las Naciones Unidas (ONU) abarca la prevención y conservación de los océanos y mares.

Neotropical freshwater fisheries : A dataset of occurrence and abundance of freshwater fishes in the Neotropics

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.
