Plant litter decomposition in a semi-arid ecosystem controlled by photodegradation

  author={Amy T. Austin and Luc{\'i}a Vivanco},
The carbon balance in terrestrial ecosystems is determined by the difference between inputs from primary production and the return of carbon to the atmosphere through decomposition of organic matter. Our understanding of the factors that control carbon turnover in water-limited ecosystems is limited, however, as studies of litter decomposition have shown contradictory results and only a modest correlation with precipitation. Here we evaluate the influence of solar radiation, soil biotic… 

The Role of Photodegradation in Surface Litter Decomposition Across a Grassland Ecosystem Precipitation Gradient

Differences in litter decomposition patterns among mesic, semiarid, and arid grassland ecosystems cannot be accurately explained by variation in temperature, moisture, and litter chemistry alone. We

Understanding litter decomposition in semiarid ecosystems: linking leaf traits, UV exposure and rainfall variability

Both the carry-over effects of photodegradation and litter quality, modulated by inter-annual variability in rainfall, can explain the marked differences in decomposition rates and the frequent decoupling between rainfall and litter decomposition observed in semiarid ecosystems.

Litter Decomposition in a Semiarid Dune Grassland: Neutral Effect of Water Supply and Inhibitory Effect of Nitrogen Addition

It is suggested that increasing precipitation hardly facilitates ecosystem carbon turnover but atmospheric N deposition can enhance carbon sequestration and nitrogen retention in desertified dune grasslands of northern China.

Nutrient dynamics during photodegradation of plant litter in the Sonoran Desert

The contribution of photodegradation to litter decomposition in a temperate forest gap and understorey

It is concluded that photodegradation, modulated by litter quality, is an important driver of decomposition, not just in arid areas, but also in mesic ecosystems such as temperate deciduous forests following gap opening.

Biotic degradation at night, abiotic degradation at day: positive feedbacks on litter decomposition in drylands

It is shown that in the absence of precipitation, absorption of dew and water vapor by litter in the field enables microbial degradation at night, which enhances the understanding of carbon turnover in drylands, which should improve the predictions of the long-term trend of global carbon sequestration.

Sunlight Doubles Aboveground Carbon Loss in a Seasonally Dry Woodland in Patagonia

It is demonstrated that direct photodegradation and its legacy, associated with increased microbial access to labile carbohydrates, are responsible for the acceleration of aboveground C turnover in this Mediterranean-type climate.



Differential Controls of Water Input on Litter Decomposition and Nitrogen Dynamics in the Patagonian Steppe

Studies of the effects of precipitation on litter decomposition and nitrogen mineralization in arid and semiarid environments have demonstrated contradictory results. We conducted a manipulative

Limited carbon storage in soil and litter of experimental forest plots under increased atmospheric CO2

A significant accumulation of carbon is reported in the litter layer of experimental forest plots after three years of growth at increased CO2 concentrations, suggesting that significant, long-term net carbon sequestration in forest soils is unlikely.

Effects of increasing ultraviolet B radiation on decomposition and soil organic matter dynamics: a synthesis and modelling study

The net effect of increasing ultraviolet B radiation levels on ecosystems is unknown. Most of the relevant ecological research has focused on the responses of living plants and algae to ultraviolet B

Abiotic and Biotic Factors in Litter Decomposition in a Sermiarid Grassland

Decomposition of grass leaf litter was studied on a shortgrass prairie using chemicals (HgC12 and CuSO4) to prevent microbial activity (abiotic treatment), 53-/im nylon mesh to exclude mesofauna

Arctic microorganisms respond more to elevated UV-B radiation than CO2

It is shown that 5 years of exposure of a subarctic heath to enhanced UV-B radiation both alone and in combination with elevated CO2 resulted in significant changes in the C:N ratio and in the bacterial community structure of the soil microbial biomass.


Solar radiation causes considerable photochemical effects on dissolved or- ganic matter (DOM) from both fresh and marine waters. Photooxidation of DOM to dis- solved inorganic carbon (DIC) has been

Ecosystem carbon loss with woody plant invasion of grasslands

A clear negative relationship between precipitation and changes in soil organic carbon and nitrogen content when grasslands were invaded by woody vegetation is found, with drier sites gaining, and wetter sites losing, soilorganic carbon.

Solar UV‐B decreases decomposition in herbaceous plant litter in Tierra del Fuego, Argentina: potential role of an altered decomposer community

The results demonstrate that, in this ecosystem, the effects of UV-B radiation on decomposition apparently occurred mostly through changes in the fungal community, while changes in photochemical breakdown appeared to be less important.

Long‐term dynamics of pine and hardwood litter in contrasting environments: toward a global model of decomposition

We analysed data on mass loss after five years of decomposition in the field from both fine root and leaf litters from two highly contrasting trees, Drypetes glauca, a tropical hardwood tree from
