Forest Land Use Transitions Dominate Net Ecosystem Productivity in Northeast China

Ecosystem Health and Sustainability
Net ecosystem productivity (NEP) represents a critical indicator of terrestrial carbon cycle dynamics. Despite Northeast China’s importance as an important carbon sink region, 3 things about it remain poorly quantified: recent NEP trends, how multiple ...

Gradient‐Oxidized Bacterial Cellulose for Self‐Sustained Soil Moisture Sensing

Advanced Science, EarlyView.
An asymmetric encapsulated bacterial cellulose device integrates a gradient‐oxidized BC framework with a LiCl‐doped Ecoflex hygroscopic layer, enabling self‐powered soil moisture monitoring through directional ion transport. The device sustains stable hydrovoltaic output, supports deep‐learning humidity classification, and fully biodegrades in soil ...

Blocking Honeybee Preference for Neonicotinoids by Interfering With Dopamine Signaling

Advanced Science, EarlyView.
Honeybees (Apis mellifera) paradoxically prefer nectar containing the harmful neonicotinoid thiamethoxam. This preference is associated with transient brain dopamine elevation during proboscis extension reflex (PER) responses and active feeding, and is reduced by the dopamine receptor antagonist fluphenazine.

Analysis of the spatiotemporal dynamics of grassland carbon sinks in Xinjiang via the improved CASA model

Ecological Indicators
Accurate assessment of grassland carbon sinks provides scientific data for quantifying the global carbon balance. Currently, methods for precisely calculating NPP (net primary productivity) and NEP (net ecosystem productivity) in arid grasslands are ...

Deciphering Intricacies in Directional CO2 Conversion From Electrolysis to CO2 Batteries

Advanced Energy Materials, EarlyView.
This review will delve into the inherent connections and distinctions of CO2‐directed conversion in ECO2RR and CO2 batteries, in terms of product types, catalyst selection, catalytic mechanisms, and electrochemical performances, while proposing a benchmarking framework for the evaluation of CO2 batteries and innovative CO2 battery configurations for ...

Net ecosystem productivity of temperate and boreal forests after clearcutting - a Fluxnet-Canada measurement and modelling synthesis [PDF]

, 2010
: Clearcutting strongly affects subsequent forest net ecosystem productivity (NEP). Hypotheses for ecological controls on NEP in the ecosystem model ecosys were tested with CO(2) fluxes measured by eddy covariance (EC) in three post-clearcut conifer ...

Predicting Ecosystem Net Primary Productivity by Percolation Theory and Optimality Principle

Water Resources Research
The basic partitioning of precipitation P into evapotranspiration ET and run‐off Q is known as the “central problem of hydrology.” ET depends primarily on precipitation, P, and potential evapotranspiration, PET, which are connected by the biological ...

Contrasting and interacting changes in simulated spring and summer carbon cycle extremes in European ecosystems

Environmental Research Letters, 2017
Climate extremes have the potential to cause extreme responses of terrestrial ecosystem functioning. However, it is neither straightforward to quantify and predict extreme ecosystem responses, nor to attribute these responses to specific climate drivers.

A novel probabilistic risk analysis to determine the vulnerability of ecosystems to extreme climatic events

Environmental Research Letters, 2013
We present a simple method of probabilistic risk analysis for ecosystems. The only requirements are time series—modelled or measured—of environment and ecosystem variables. Risk is defined as the product of hazard probability and ecosystem vulnerability.
