The complete chloroplast genome sequence of Podocarpus imbricatus (Podocarpaceae) and its phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2019
In this study, the complete chloroplast genome sequence of Podocarpus imbricatus (Podocarpaceae) was determined. Like other chloroplast genomes in conifers, the Podocarpus imbricatus genome did not have typical quadripartite structure. The genome was 133,

Biochemical and morphological changes during the growth kinetics of Araucaria angustifolia suspension cultures

open access: yesBrazilian Archives of Biology and Technology, 2010
Embryogenic cultures of Araucaria angustifolia were established in a BM liquid medium supplemented with 2 µM 2,4-dichlorophenoxyacetic acid, 1 µM 6-benzylaminopurine and 1 µM kinetin (BM2) and in a BM medium free of growth regulators (BM0).

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.

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: "

Growth modelling of living Pinaceae unlocks the stature of ancient relatives

open access: yesPalaeontology, Volume 69, Issue 5, September/October 2026.
Abstract Today, Pinaceae are the largest family of living conifers in the world, yet we know little about their tree heights in the late Mesozoic and Cenozoic. A statistically sound approach to estimate ancient tree height from fossil log diameter is to extrapolate size based on height–diameter relationships in living relatives.

Isolating and Measuring the Growth and Morphology of Pro-embryogenic Masses in Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae)

open access: yesBio-Protocol, 2016
Embryogenic suspension cultures of Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae) can be used as a model to test the effects of compounds added to the culture medium on the cellular growth and morphology of Pro-Embryogenic Masses (PEMs).

Host Range and Disease Potential of Colletotrichum aotearoa in Australian Native Plants

open access: yesPlant Pathology, Volume 75, Issue 4, July‐August 2026.
The broad host range of Colletotrichum aotearoa (including several Banksia species), together with its ability to cause asymptomatic infection, suggests that it may be an important pathogen of Australian native plants. ABSTRACT Colletotrichum aotearoa, originally described from various native species in New Zealand, has since been reported in Australia

The Evolution of Hutchinsonian Climatic Niche Hypervolumes in Gymnosperms

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 6, June 2026.
ABSTRACT Aim The niche is a fundamental concept in theoretical and experimental ecology and is used to describe a wide range of ecological processes from species' interactions with the environment to community assemblies. A common way to represent the niche is through a multidimensional geometry known as the Hutchinsonian niche hypervolume.

Drmno lignite field (Kostolac basin, Serbia): Origin and palaeoenvironmental implications from petrological and organic geochemical studies [PDF]

open access: yesJournal of the Serbian Chemical Society, 2012
The objective of the study was to determine the origin and to reconstruct the geological evolution of lignites from the Drmno field (Kostolac Basin, Serbia). For this purpose petrological and organic geochemical analyses were used. Coal from the Drmno
