Are Growth Bands in Macadamia integrifolia Annual?

Ecological Management &Restoration, Volume 27, Issue 3, September 2026.
ABSTRACT Although two of the four Australian endemic Macadamia species are well known as horticultural crops, little is understood about their use by First Nations peoples or their longevity. Robust age estimation of the age attainable by Macadamia integrifolia would help inform conservation planning and cultivation.

The Temporal Imperative: Palaeo‐Proxies and Nature‐Based Solutions for Resilient Natural Inland Wetland Conservation and Management in Southeast Asia—A Systematic Review

Ecological Management &Restoration, Volume 27, Issue 3, September 2026.
ABSTRACT Natural inland wetlands in Southeast Asia provide key biodiversity, hydrological, carbon‐storage and livelihood functions, but are increasingly affected by land‐use change, fire, hydrological modification and climate change and variability.

Old Soil Organic Matter Has a Low Carbon:Nitrogen Ratio—A Global Meta‐Analysis About 14C and Soil Stoichiometry

Global Change Biology, Volume 32, Issue 9, September 2026.
This study demonstrates that old SOM has a low C:N ratio compared to young SOM, indicating that N is preferentially retained in soils compared to organic C. Furthermore, the study shows that the C:N ratio and the Δ14C are higher in forest and shrubland soils than in grassland and cropland soils throughout the soil profile. ABSTRACT Soil organic matter (

Characterization of coesite‐bearing impact melt glass from the Hapcheon crater, Korea: Trimodal phase architecture, shock metamorphism, and implications for 40Ar/39Ar geochronology

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2233-2257, September 2026.
Abstract We present the first micrometer‐scale, phase‐resolved compositional characterization of impact melt glass from the Hapcheon crater (~1.4 km apparent diameter), the first confirmed impact structure on the Korean Peninsula, integrating EPMA‐WDS (5 μm spot), confocal Raman spectroscopy (<1 μm spot), XRD, and 40Ar/39Ar step‐heating geochronology ...

Sedimentary Ancient DNA Tracks Multi‐Kingdom Ecosystem Reorganizations Following Sequential Human Land Use at Crawford Lake

Molecular Ecology, Volume 35, Issue 17, September 2026.
ABSTRACT Crawford Lake has an exceptional stratigraphic record that began recording biannual (varved) sedimentation in the lake basin ~750 years ago, preserving evidence of shifting cultural zones and agricultural practices, from Late Woodland Period Indigenous agriculturalists to the impacts of industrialization during the late 19th century.
