Poaceae is a cosmopolitan family that includes species found in both forest and grassland formations. The objective of this study was to carry out the first floristic survey of Poaceae in the Parque Estadual do Guartelá (PEG), one of the last remnants of native grassland vegetation in the State of Paraná, Brazil, and provide resources to assist the identification of genera and species. The survey was conducted based on field collections and searches in the Species Link online database. In the PEG, Poaceae is represented by 29 genera and 54 species, being Paspalum L. (eight spp.), Andropogon L. (five spp.) and Eragrostis Wolf (four spp.) the richest genera. The number of species in the PEG was incremented by 29 new records. In addition, five species were classified as exotic, five as endemic to Brazil, and two were considered least concern in relation to their conservation. We also present information regarding the distribution, habitat and conservation status for each species.

Cyperaceae is the third largest family among the monocotyledons and is highly represented in grassland environments. The aim of the present study was to conduct a floristic inventory of Cyperaceae in the grasslands of Guartelá State Park (GSP) and to elaborate keys to identify the species, the first for this family in this vegetation type in Paraná state. The GSP is home to relictual vegetation in Paraná, where grassland phytophysiognomies predominate, especially in open areas and rocky outcrops. The inventory was based on field collections and database searches. The family Cyperaceae is represented in the GSP by 32 taxa belonging to seven genera, with Rhynchospora (11 spp.), Bulbostylis (8 spp.), and Cyperus (7 spp.) being the genera with the greatest richness. It should be noted that all the species are native and two are endemic to Brazil. Species occurrence was recorded both in drylands and wetlands environments, emphasizing the importance of microenvironmental conservation in the park. The main literature sources for each genus, as well as information regarding distribution and habitat, are here provided.

Prospecção do impacto das ferramentas de software criadas pela DSPGeo nas diversas etapas da cadeia de upstream para prospecção de Óleo e Gás Tainá Souza Resumo Nesse projeto foi realizada uma análise do impacto mercadológico das ferramentas de software desenvolvidas pela empresa DSPGeo, na cadeia de exploração e produção de petróleo e gás. Procurou-se identificar a possibilidade de inovações internas na DSPGeo, relacionadas a novos mercados, não considerados atualmente, como o uso dos softwares para dados prestack no setor de energia geotérmica. Consequentemente, efetuou-se um estudo de viabilidade técnico-econômica para uma melhor tomada de decisão relacionada às alterações das ferramentas existentes e suas novas aplicações, assim como do desenvolvimento de uma nova ferramenta de acordo com a necessidade do mercado.
