Magnetic Resonance in Chemistry, EarlyView.We establish a two‐dimensional solid‐state NMR 13C chemical shift mapping framework that resolves diagnostic features and explicitly visualizes spectral overlap among guaiacyl and syringyl lignin substructures in intact plant cell walls. Application across Arabidopsis genotypes and developmental stages, hardwoods, and softwood reveals distinct lignin ...

Estimates of genetic parameters of wood traits for sawn timber production in Eucalyptus grandis
Genetics and Molecular Biology, 2004 In this study, the breeding perspectives of 41 open-pollinated progenies of Eucalyptus grandis were evaluated based on their wood traits. The progenies were distributed in two experiments in a randomized complete block design, with three replicates and ...

Eucalypt oils for the control of Parthenium (Parthenium hysterophorus L.)
, 1998 Eucalypt oils from Eucalyptus globulus and E. citriodora exert deleterious effects on Parthenium hysterophorus - a noxious weed. The germination of the weed was inhibited and the chlorophyll content and cellular respiration of the mature plants exposed ...

Interplanetary frontiers: terraforming from an invasion science perspective
Oikos, EarlyView.The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Coexisting ant species differ in ability to meet their intrinsic nutritional needs
Oikos, EarlyView.Coexisting species are often assumed to reduce competition by foraging for foods that differ in nutrient composition, but few studies test whether field nutritional differences correspond to intrinsic differences in macronutrient selectivity. We compared field estimates of worker trophic position (tissue isotopes: δ15N) and worker tissue stoichiometry (

Designing for biodiversity data in place: Species, encounters, and interfaces
People and Nature, EarlyView.Abstract Species occurrence data, which records the presence of an organism at a point in space and time, is central to environmental science and its opening up to new forms of participation such as citizen science. Such data are increasingly aggregated and mobilised, reaching diverse audiences.

Emergent media narratives on land conflicts in a global biocultural diversity hotspot
People and Nature, EarlyView.Abstract Land conflicts (LCs) represent major challenges in regions where limited resources are contested by diverse actors. The triple frontier of the bioculturally diverse Alto Paraná Atlantic Forests (APAF) ecoregion concentrates some of the most intense LCs in South America.
