Leaf anatomy of Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae)

(Leaf anatomy of Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae)). Immature and mature leaves of juvenile and adult plants of Araucaria angustifolia (Araucariaceae) were observed with the objective of updating the morphoanatomical data of the leaves of this species, which were restricted to basic descriptions in previous studies. The observations, made in optical allowed to establish an...

Patterns of genetic diversity in southern and southeastern Araucaria angustifolia (Bert.) O. Kuntze relict populations

Habitat fragmentation and a decrease in population size may lead to a loss in population genetic diversity. For the first time, the reduction in genetic diversity in the northernmost limit of natural occurence (southeastern Brazil) of Araucaria angustifolia in comparison with populations in the main area of the species continuous natural distribution (southern Brazil), was tested. The 673 AFLPs...

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

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. Allele frequencies are altered by natural selection and b...
