The Evolution of Hutchinsonian Climatic Niche Hypervolumes in Gymnosperms

Global 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.

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

Brazilian 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).

Forest Disturbance Drives Changes in the Functional Traits of Soil Bacteria: A Metagenomic Study of Kauri (Agathis australis) Forest Ecosystems

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This study reveals how ecological disturbances reshape the structure and function of soil bacterial communities in kauri forests, which are critical for ecosystem resilience. By linking disturbance regimes to shifts in bacterial diversity and functional capacity, it highlights the wider effects of ecosystem disturbance on soil ecological function ...

Comparison of seedling growth among three co-occurring varieties of Araucaria angustifolia (Bertol.) Kuntze under greenhouse conditions

Acta 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: "

Arbuscular Mycorrhizal Fungi Colonise the Nodules of Phosphite‐Treated Agathis australis

New Zealand Journal of Botany, Volume 64, Issue 1, March 2026.
Agathis australis (kauri), the only member of the ancient conifer family Araucariaceae in New Zealand, is colonised by arbuscular mycorrhizal (AM) fungi. The survival of A. australis is threatened by an Oomycota, Phytophthora agathidicida, the causal agent of kauri dieback. Phosphite injections into the trunk are the primary treatment for kauri dieback

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

Bio-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).

Bright and Long: Day Length Modulates the Phenology of Two Myrtaceae Species in Upper Montane Mixed Ombrophilous Forest

Austral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT The Upper Montane Mixed Ombrophilous Forest is a humid montane ecosystem characterised by cold winters and a rich Myrtaceae flora. We investigated the vegetative and reproductive phenology of Myrceugenia euosma (O. Berg) D. Legrand and Siphoneugena reitzii D.

Differential seedling survival of early‐planted, late‐successional trees: Results from three forest restoration experiments

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
Successful forest restoration starts early: Across three restored sites, late‐successional trees (n = 1840) established well when planted at the same time as pioneers. A 2‐m spacing maximized survival, revealing facilitation–competition trade‐offs, with outcomes also shaped by species identity and microhabitat.

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

Journal 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
