1. An alternative energy generation from charcoal produced from Brazilian pine (Araucaria angustifolia (Bert.) O. Ktze) seed residues
The perspective is that the energy demand will grow in the coming decades worldwide. The search for renewable energy sources is urgent and necessary. Residual biomass may be a promising source of raw material for obtaining bioenergy. Thus, this research sought to evaluate the energetic and physicochemical properties of residues from the seeds of Brazilian pi

2. Energy balance and CO2 emission in mechanized biomass harvesting in pine stands under thinning
Abstract: Biomass is an important component of the Brazilian energy matrix, with a potential contribution of co-products from thinned forests. The aim of this work was to evaluate the energy balance and CO2 potential emission in mechanized biomass harvesting operations in Pinus taeda stands at 9 and 10 years-old and under thinning, searching to support the

3. Araucaria angustifolia chloroplast genome sequence and its relation to other Araucariaceae
Abstract Araucaria angustifolia is endemic to southern Brazil. Known as Brazilian pine, A. angustifolia is the only native conifer species with economic and social relevance in this country. Due to massive exploitation, it has suffered a significant population decline and currently is classified as critically endangered. This encouraged the scientific commun

4. Growth and quality of Brazilian pine tree seedlings as affected by container type and volume
Resumo Araucaria angustifolia (Bert.) O. Kuntze (Araucariaceae), popularmente conhecida como araucária e pinheiro brasileiro, pode ser cultivada em função de suas sementes comestíveis (pinhões), propriedades medicinais e atributos ornamentais. O objetivo foi avaliar o crescimento de parte aérea e radicular e a qualidade geral de mudas de A. angustifoli

6. Brazilian Pine (Araucaria angustifolia (Bertol.) Kuntze) Ethnoecology in the Mantiqueira Atlantic Forest
ABSTRACT Araucaria angustifolia is under the domain of the Atlantic Forest, classified as Mixed Ombrophilous Forest (FOM). It is a native species critically threatened due to the intense exploration, to the point of exhaustion, of its natural reserves. This study aims to present the ethnoecological knowledge regarding this species in a community located in t

7. Atrial fibrillation in acute Chagas disease acquired via oral transmission: a case report
Abstract Atrial fibrillation (AF), a type of supraventricular arrhythmia increases the risk of thromboembolism. Chagas disease has been reported in the Brazilian Amazon region over approximately 20 years. Cardiac abnormalities are recorded in at least 50% of patients and among these, 3.3% develop AF. We describe a case of a 41-year-old man from Muaná, Pará

8. Storage Potential of Local Brazilian Pine Seed Varieties
ABSTRACT Brazilian pine seeds (Araucaria angustifolia) are recalcitrant, and there are no studies evaluating the longevity of their different varieties. Our objective was to evaluate the capacity of different varieties of Brazilian pine seeds to maintain their physiological quality during storage. Seeds of the varieties: sancti josephi (I), angustifolia (II)

9. Soil Fertility and Electrical Conductivity Affected by Organic Waste Rates and Nutrient Inputs
ABSTRACT The composition of organic waste (OW) and its effect on soil processes may change soil fertility and electrical conductivity (EC). The side effects of waste use in crop fertilization are poorly understood for Brazilian soils. This study examined the effect of the addition of 15 different organic wastes to Oxisols and a Neosol on pH, base saturation,

10. Ultra-low temperature conservation of Brazilian Pine embryogenic cultures
Este estudo objetivou estabelecer um protocolo de criopreservação para culturas embriogênicas de A. angustifolia, possibilitando a conservação ex situ da espécie. Culturas embriogênicas foram estabelecidas a partir de sementes imaturas e tratadas com variações das soluções crioprotetoras SuDG, SoD e PVS2 antes da imersão em nitrogênio líquido.

11. First report and characterization of Fusarium circinatum, the causal agent of pitch canker in Brazil
Pitch canker is one of the most important diseases of pine trees worldwide, including South America. The causal agent of this disease is Fusarium circinatum, a member of the Gibberella fujikuroi complex (GFC). In South America, the species is reported from Colombia, Uruguay and Chile, but is considered a quarantine organism in Brazil. In this study we charac

12. Reproductive biology and early establishment of Pinus elliottii var. elliottii in Brazilian sandy coastal plain vegetation: implications for biological invasion
Pinus is the most invasive woody taxon, exceeded only by herbaceous plants. This study reports the reproductive biology and early establishment of Pinus elliottii Engelm. var. elliottii, describing its invasive properties in a protected natural area of the Brazilian coastal sandy plains. We evaluated the seed germination and rain, longevity of seed viability
