Evolutionary diversification of new Caledonian Araucaria.

open access: yesPLoS ONE, 2014
New Caledonia is a global biodiversity hotspot. Hypotheses for its biotic richness suggest either that the island is a 'museum' for an old Gondwana biota or alternatively it has developed following relatively recent long distance dispersal and in situ ...

Phylogenetic biogeography of Araucaria (Araucariaceae)

open access: yesПроблемы ботаники южной сибири и монголии, 2020
The analysis of molecular data of all 19 recent species of the genus Araucaria Juss. (Araucariaceae) wascarried out and original cladogramm was build. Based on the cladogramm, the map of correlations of the phylogeneticrelationships and the distribution of all recent Araucaria species is proposed.

Arachidonic and eicosapentaenoic acids in Araucariaceae, a unique feature among seed plants

open access: yesOléagineux, Corps gras, Lipides, 2000
It is generally admitted that seed plants (spermaphytes) are unable to synthesize either arachidonic or eicosapentaenoic acids (AA and EPA), the classic essential fatty acids in animals.

Wildfires in the Campanian of James Ross Island: a new macro-charcoal record for the Antarctic Peninsula

open access: yesPolar Research, 2021
The Cretaceous “high-fire” period was a global event that reached almost all continental masses during that period in Earth’s history. The extensive wildfires directly affected plant communities.

New data on the stem and leaf anatomy of two conifers from the Lower Cretaceous of the Araripe Basin, northeastern Brazil, and their taxonomic and paleoecological implications. [PDF]

open access: yesPLoS ONE, 2017
Pseudofrenelopsis and Brachyphyllum are two conifers that were part of the Lower Cretaceous (Aptian) taphoflora of the Crato Formation, Araripe Basin, northeastern Brazil. The former genus includes, so far, P.

Growth inhibition of an Araucaria angustifolia (Coniferopsida) fungal seed pathogen, Neofusicoccum parvum, by soil streptomycetes [PDF]

open access: yes, 2013
Background: Araucariaceae are important forest trees of the southern hemisphere. Life expectancy of their seedlings can largely be reduced by fungal infections.

Comparison of species classification models of mass spectrometry data : kernel discriminant analysis vs. random forest : a case study of Afrormosia (Pericopsis elata (Harms) Meeuwen) [PDF]

open access: yes, 2017
Rationale: The genus Pericopsis includes four tree species of which only Pericopsis elata (Harms) Meeuwen is of commercial interest. Enforcement officers might have difficulties discerning this CITES-listed species from some other tropical African timber
