Nucleotidic variability of the CAD gene in Eucalyptus urophylla population along altitudinal gradient in Timor Island [PDF]

open access: yes, 2007
Single nucleotide polymorphism (SNP) in candidate genes offers new perspectives to analyse the impact of natural selection on gene variation along environmental gradient and to understand the molecular basis of adaptation.

Do Eucalypt Species Display Similar Potential Niche Patterns to North American Trees?

open access: yesAustral Ecology, Volume 50, Issue 7, July 2025.
ABSTRACT A 2024 paper in Science described the realised and potential thermal niches of 188 North American tree species in terms of mean annual temperature (MAT). Using PlantSearch data from outside species‐native distributions, it was found that species potential niches displayed a ‘centrifugal organisation’ of thermal niches.

Genetic variability of growth and wood chemical properties in a clonal population of Eucalyptus urophylla x Eucalyptus grandis in the Congo

open access: yes, 2017
Thirty-four Eucalyptus urophylla x Eucalyptus grandis hybrids were evaluated with a view to selecting for improved growth and wood-quality traits for plantations in the Congo. Height, circumference at breast height and volume were measured at 12, 27, 37,

Land‐Use Change Enhances Organic Phosphorus Pools in Oxisols in Brazil's New Agricultural Frontier

open access: yesSoil Use and Management, Volume 41, Issue 3, July‐September 2025.
ABSTRACT Land‐use types and management systems can affect the availability of phosphorus (P) by modifying its compartments. The aim of this study was to evaluate the organic and inorganic fractions of P in an Oxisol in the Cerrado region of Brazil, considering various land‐use types and management systems and the period of application.

No Direct Observational Evidence for Basidiospore‐Derived Infection of Eucalypt and Rose Apple (Syzygium jambos) by the Myrtle Rust Pathogen, Austropuccinia psidii, From Brazil

open access: yesForest Pathology, Volume 55, Issue 3, June 2025.
ABSTRACT Myrtle rust caused by Austropuccinia psidii is one of the most important diseases affecting eucalypts (Eucalyptus spp. and Corymbia spp.) in Brazil. Asexual spores of the myrtle pathogen, urediniospores, give rise to infection of young tissues (e.g., leaf, stem, flower and fruit) of the myrtaceous hosts.
