Genetic diversity and divergence applied to Enviromental services for Araucaria angustifolia(Brazil) [PDF]

open access: yesBMC Proceedings, 2011
Humans derive many utilitarian benefits from the environmental services of biotas and ecosystems.Yet ecosystem, species and genetic levels is increasingly lost from agricultural landscapes mainly due to maximisation of production [1,2]. The genetic variability is a result of several forces including mutation, recombination and gene flow.

Low abundance of phytophagous nematodes under invasive exotic Pinus elliottii - enemy release and plant-soil feedbacks. [PDF]

open access: yesNew Phytol
Summary According to the enemy release hypothesis (ERH), the fitness of exotic plants and their capacity to become invasive in their area of introduction may partly be attributable to the loss of their natural enemies. Invasive species may also benefit from modifying soil attributes and thereby creating a positive soil–plant feedback.

Structure and Tree Diversity in a Mixed Ombrophilous Forest Remnant, Southern Brazil

open access: yesFloresta e Ambiente, 2021
This study aimed to determine the tree structure, floristic composition and species diversity in the Araucaria State Park, southern Brazil. We allocated 100 plots of 100 m2 (1 ha) each one, and we recorded all trees with diameters at breast height ≥ 5 cm.

Occurrence of diazotrophic bacteria in Araucaria angustifolia [PDF]

open access: yesScientia Agricola, 2007
Araucaria angustifolia é uma espécie arbórea ameaçada de extinção e toda a comunidade viva das Florestas de Araucária deve ser estudada com a finalidade de sua preservação. Bactérias diazotróficas apresentam grande importância para a manutenção de ecossistemas, mas sua ocorrência nunca foi pesquisada em araucária.
