  Unignorable photodegradation: Solar radiation is accelerating carbon cycle process of temperate forest ecosystems

  Litter decomposition is critical for carbon (C) cycling in terrestrial ecosystems. Sunlight, as the essential energy for the biogeochemical cycling, can directly break down natural organic matter and accelerate decomposition through photodegradation. However, the role of photodegradation in litter decomposition has been neglected especially in productive mesic ecosystems, where litter is exposed to a heterogeneous radiation environment. Obtaining a more-complete picture of the drivers of litter decay is key to predicting how terrestrial C and nutrient cycles respond to climate changes.

  Hydraulic Failure Is Involved in the Decline of Sand-fixing Salix Gordejevii Shrubs

  A research team led by Prof. Dr. Guangyou Hao from the Institute of Applied Ecology of the Chinese Academy of Sciences measured the xylem hydraulics, sap flow, water relations and non-structural carbohydrate reserves for S. gordejevii plants that respectively inhabited interdune, leeward and windward positions of active dunes with contrasting soil water regimes.

  Increasing Effects of Remnant Seed Sources on Post-volcanic-eruption Forest Landscape Recovery

  Volcano eruption is a catastrophic disturbance, which can destroy almost all forest vegetation, forcing forest succession to restart. Post-volcanic-eruption forest landscape recovery is largely driven by available seed sources and seed dispersal pattern.

  Researchers Firstly Uncover Viral Abundance and Diversity in Oil Reservoir

  Viruses are considered to be the most abundant and diverse organisms in the world. They are ubiquitous in soil, ocean, river, wetland and other ecosystems, and play important roles in regulating structure and function of ecosystems.

  Seasonal Quantitative Evaluation of the Balance between Ecosystem Services Supply and Demand Are of Significance for Targeted Decision Making

  The paradox of compact cities in terms of ecosystem services supply (ESs) and demand (ESd) is evidenced. Most researches established that ESs and ESd are spatially unbalanced, especially a major mismatch pattern showed in central urban area. But some researches showed unusually well balance in central city. Scientists notice that all those researches are based on averaged yearly data which would minimize the impact of extreme values.

  C-N-P Interactions Are of Significance for Understanding the Rhizosphere Priming

  Rhizosphere priming effect (RPE) is a key rhizosphere process in mediating soil organic matter (SOM) decomposition and nutrient cycling. The RPE can affect nutrient supply to plants, but the RPE itself may also be affected by soil nutrient availability.
