Selected Properties ofAraucaria AngustifoliaandAraucaria AraucanaSeed Protein

International Journal of Food Properties, 2011
Araucaria angustifolia and Araucaria araucana are coniferous trees with large and nutritious seeds. The structure and nutritional properties of the proteins of these seeds were studied. About 70% of the proteins of the gametophyte were soluble in distilled water, although their solubility decreased drastically in raw seed flour.

Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

Ecological Entomology, Volume 51, Issue 3, Page 558-569, June 2026.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

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

Scientia 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 ...
