Geoprocessamento e sensoriamento remoto:
De acordo com o Código Florestal, pela Lei n° 12.651 de 25 de maio de 2012, é proibido o uso fogo, exceto em algumas condições estabelecidas. Desta maneira, o uso do fogo, mesmo sendo controlado, sem a autorização, é considerado ilegal. Os crimes ambientais relacionados ao uso indevido do fogo acabam não sendo monitorados e fiscalizados de forma ...

Environmental Controls on the Riverine Export of Dissolved Black Carbon
Abstract Each year, tropical rivers export a dissolved organic carbon (DOC) flux to the global oceans that is equivalent to ~4% of the global land sink for atmospheric CO2. Among the most refractory fractions of terrigenous DOC is dissolved black carbon (DBC), which constitutes ~10% of the total DOC flux and derives from the charcoal and soot (aerosol)

Correção Atmosférica em Sensoriamento Remoto: Uma Revisão
A correção atmosférica é um procedimento necessário em estudos de sensoriamento remoto com foco nas propriedades físicas, químicas e biológicas de alvos. Em abordagens multitemporais e/ou multisensor, a correção atmosférica é fundamental para a obtenção de medidas de reflectância de superfície representativas das características espectrais dos alvos ...

SpiderATLAS: A Database of Spider Traits and Distributions in the Brazilian Atlantic Forest
ABSTRACT Aim Biodiversity shortfalls related to limited knowledge about geographic distribution (Wallacean) and species traits (Raunkiæran) are extremely common in many animal groups and perhaps more evident in invertebrate groups such as spiders. This lack of knowledge could present challenges for researchers investigating the response and effects of ...
