HEIGHT-DIAMETER RELATIONSHIPS FOR Araucaria angustifolia (BERTOL.) KUNTZE IN SOUTHERN BRAZIL [PDF]

open access: yesCERNE, 2016
ABSTRACT Height-diameter relationships are used in order to make forest inventories less expensive and to assess growth and yield. This study aimed to develop height-diameter models for individual trees of Araucaria angustifolia (Bertol.) Kuntze for different locations and growth conditions in Southern Brazil. Our data include locations of at least one

Spore density and root colonization by arbuscular mycorrhizal fungi in preserved or disturbed Araucaria angustifolia (Bert.) O. Ktze. ecosystems Densidade de esporos e colonização radicular por fungos microrrízicos arbusculares em ecossistemas de Araucaria angustifolia (Bert.) O. Ktze. preservados e impactados

open access: yesScientia Agricola, 2006
Araucaria angustifolia (Bert.) O. Ktze., a native forest tree from Brazil, is under extinction risk. This tree depends on arbuscular mycorrhizal fungi for growth and development, especially in tropical low-P soils but, despite being a conifer, Araucaria ...

Availability of a Keystone Plant Resource Reduces Niche Overlap and Drives Distinct Species‐Specific Changes in Niche Breadth Among Small Rodents

open access: yesIntegrative Zoology, EarlyView.
We investigated how three rodent species respond to the seasonal availability of Araucaria angustifolia seeds. While Oligoryzomys spp. increased seed consumption and abundance during seed production, the more insectivorous Akodon paranaensis maintained a broader diet.

Comparison of seedling growth among three co-occurring varieties of Araucaria angustifolia (Bertol.) Kuntze under greenhouse conditions

open access: yesActa Botânica Brasílica, 2010
Araucaria angustifolia (Bertol.) Kuntze is a tall, long-lived tree species, which grows as an emergent tree in the araucaria forests of southern Brazil. Four varieties have been described for this species, and three of them were selected for this study: "

Scientific novel: Araucaria angustifolia branch may be converted into orthotropic trunk by grafting

open access: yesRevista Ceres, 2020
Grafting technique has been presented as an alternative for Araucaria angustifolia propagation. However, vegetative rescuing mature trees and obtaining large numbers of propagules is difficult, because the use of branch grafts has not been indicated due ...

Fossil wood reveals climate stress and fungal decomposition in Late Triassic (Norian) forests in central Europe

open access: yesPapers in Palaeontology, Volume 12, Issue 5, September/October 2026.
Abstract Late Triassic forests in Central Europe developed under a seasonal sub‐tropical climate while the supercontinent Pangea was breaking up. Although permineralized fossil wood from this interval is abundant, its palaeoclimatic and palaeoecological significance has so far remained largely unexplored.

Advanced Sorbent Materials in Solid‐Phase Extraction: A Decade of Innovation and Future Perspectives

open access: yesChemistry–Methods, Volume 6, Issue 8, August 2026.
This review systematically summarizes five families of advanced sorbent materials for solid‐phase extraction (SPE): nanocarbons, porous frameworks (MOFs/COFs), smart polymers, biomass‐derived sorbents, and multifunctional composites. Key molecular interactions (π–π stacking, hydrogen bonding, electrostatic attraction, host–guest recognition) are ...

QUALIDADE FISIOLÓGICA DE SEMENTES DE Araucaria angustifolia (Bertol.) Kuntze SUBMETIDAS A DIFERENTES CONDIÇÕES DE ARMAZENAMENTO E A ESCARIFICAÇÃO [PDF]

open access: yesCiência Florestal, 2006
As sementes de Araucaria angustifolia (Bertol.) Kuntze (pinheiro-do-Paraná) são recalcitrantes e, portanto, perdem rapidamente a viabilidade após a colheita, o que dificulta a sua utilização na produção de mudas. Este trabalho teve como objetivos avaliar

Improved method for isolation of coupled mitochondria of Araucaria angustifolia (Bert.) O. Kuntze

open access: yesBrazilian Archives of Biology and Technology, 2004
A method for the isolation of coupled mitochondria from the callus of Araucaria angustifolia is described for the first time. Mitochondria were isolated from embryogenic callus of A. angustifolia. They were metabolically active, able to sustain oxidative
