Above-ground biomass and productivity in a rain forest of eastern South America [PDF]

open access: yes, 2008
: The dynamics of tropical forest woody plants was studied at the Nouragues Field Station, central French Guiana. Stem density, basal area, above-ground biomass and above-ground net primary productivity, including the contribution of litterfall, were ...

Single‐Cell Transcriptome Reveals Aquaporin‐Mediated Carbon Nanosol‐Induced Growth Promotion of Plants

open access: yesAdvanced Science, EarlyView.
Carbon nanosol (CNS) exhibits rapid root penetration capacity, enhancing plant growth through boosting stomatal density and antioxidative enzyme activity. Single‐cell transcriptomic profiling uncovers cell type‐specific gene expression patterns and developmental trajectories during CNS‐mediated growth promotion.

Resolving the measurement uncertainty paradox in ecological management [PDF]

open access: yesarXiv, 2018
Ecological management and decision-making typically focus on uncertainty about the future, but surprisingly little is known about how to account for uncertainty of the present: that is, the realities of having only partial or imperfect measurements.

Solar‐Powered Hierarchical Microenvironments with Authigenic Multi‐Field Synergies for Simultaneous Extraction of Freshwater and Cesium

open access: yesAdvanced Science, EarlyView.
A biomass‐based solar‐powered hierarchical self‐extraction micro‐network (BSSM) is first proposed to achieve freshwater production and Cs+ extraction. This study establishes a transformative paradigm for resource recovery, providing a scalable and eco‐friendly panacea to address pressing global issues, including water scarcity, nuclear pollution, and ...

Novel approach for identifying VOC emission characteristics based on mobile monitoring platform data and deep learning: Application of source apportionment in a chemical industrial park

open access: yesHeliyon
Refined volatile organic compound (VOC) emission characteristics are crucial for accurate source apportionment in chemical industrial parks. The data from mobile monitoring platforms in chemical industrial parks contain pollution information that is not ...

Seed mass diversity along resource gradients: the role of allometric growth rate and size-asymmetric competition

open access: yes, 2018
The large variation in seed mass among species inspired a vast array of theoretical and empirical research attempting to explain this variation. So far, seed mass variation was investigated by two classes of studies: one class focuses on species varying ...

Living Close to Your Neighbors: The Importance of Both Competition and Facilitation in Plant Communities [PDF]

open access: yes, 2014
Recent work has demonstrated that competition and facilitation likely operate jointly in plant communities, but teasing out the relative role of each has proven difficult.

REVIEW: The detection of aquatic animal species using environmental DNA – a review of eDNA as a survey tool in ecology

open access: yes, 2014
Summary 1. Knowledge of species distribution is critical to ecological management and conservation biology. Effective management requires the detection of populations, which can sometimes be at low densities and is usually based on visual detection and ...
