Carbon‐Fixing Bacterial Network Complexity Mediates Soil Multifunctionality in a Panax notoginseng‐ Pinus armandii Agroforestry System

Land Degradation &Development, Volume 37, Issue 15, Page 10835-10850, September 2026.
ABSTRACT Autotrophic carbon‐fixing bacteria (CFB) are central contributors to soil carbon sequestration and biogeochemical carbon cycling in agroforestry ecosystems and can act as reliable biological indicators for evaluating agroforestry ecosystem sustainability.

A review of preferential flow and transport through root channels

Vadose Zone Journal, Volume 25, Issue 5, September/October 2026.
Abstract Preferential flow can contribute up to 80%–90% of the flow and transport in the vadose zone. The root channels are the most prevalent form of preferential pathways. They create an evolving network of preferential pathways and are biogeochemical hotspots due to preferential transport of nutrients and other organics, colonization of bacteria ...

Biogeographic Disconnect and Biotic Homogenization in the Heart of the Amazon: Dominance of Exotic Species in Urban Trees

Biotropica, Volume 58, Issue 5, September 2026.
Exotic taxa dominate the urban woody flora, with potentially invasive species posing a direct risk to adjacent primary forest remnants. Historical management has favored a simplified, cosmopolitan species pool over regional biodiversity. There is failure to implement local native‐priority mandates, offering concrete ecological targets for urban ...

Contrasting Embryogenic Trajectories Reveal Spatial Control as a Key Determinant of Embryogenic Competence in Theobroma cacao L.

Physiologia Plantarum, Volume 178, Issue 5, September/October 2026.
ABSTRACT Somatic embryogenesis (SE) in Theobroma cacao is a micropropagation technique of great importance but remains constrained by genotype recalcitrance. The cellular and molecular mechanisms distinguishing regenerative from non‐regenerative responses remain poorly understood.

How Does Glucose Addition Affect Net Carbon Balance in Top and Deep Soils in Tropical Rubber‐Based Agroforestry Systems?

Land Degradation &Development, Volume 37, Issue 14, Page 10272-10283, 30 August 2026.
ABSTRACT The priming effect, which can accelerate or suppress the mineralization of soil organic carbon (SOC), plays an important role in soil carbon cycling. However, the impact of exogenous carbon addition on SOC priming in rubber‐based agroforestry systems remains unclear.

Prediction of Hevea progeny performance in the presence of genotype-environment interaction

Brazilian Archives of Biology and Technology, 2009
Twenty two open-pollinated Hevea progenies from different parental clones of the Asian origin were tested at five sites in the Northwestern São Paulo State Brazil to investigate the progeny girth growth, rubber yield, bark thickness and plant height ...

Biomimetic Microfractals Based Flexible Triboelectric Nanogenerators

Advanced Functional Materials, Volume 36, Issue 67, 20 August 2026.
A leaf‐skeleton‐based microfractal architecture is integrated with guided CuNW networks and biomimetic triboelectric polymer layers, enabling breathable, flexible, and material‐efficient triboelectric nanogenerators. The resulting system combines enhanced charge generation and charge transport, offering potential for next‐generation self‐powered ...
