Article Synopsis
- Patchy data on litter decomposition in wetlands limits understanding of carbon storage, prompting a global study involving over 180 wetlands across multiple countries and climates.
- The study found that freshwater wetlands and tidal marshes had more organic matter remaining after decay, indicating better potential for carbon preservation in these areas.
- Elevated temperatures positively affect the decomposition of resistant organic matter, with projections suggesting an increase in decay rates by 2050; however, the impact varies by ecosystem type and highlights the need to recognize both local and global factors influencing carbon storage.
Article Synopsis
- Peatlands play a crucial role in global carbon and nitrogen cycles, holding 15 to 30% of the world's soil carbon stock, but their varying chemistry complicates global carbon inventories.
- A study analyzed 436 peat cores from 24 countries, finding significant differences in carbon, nitrogen, and organic matter content between different peatland categories, mainly influenced by pH levels.
- The results indicate predictable differences in carbon and organic matter concentrations across peatland types, which can help enhance future assessments of global peatland carbon and nitrogen stocks.
Soils have both direct and indirect impacts on available energy, but energy provision, in itself, has direct and indirect impacts on soils. Burning peats provides only approximately 0.02% of global energy supply yet emits approximately 0.

Despite the disparate timescales between functional mechanisms and molecular dynamics (MD) trajectories, functional differences are often inferred from differences in conformational ensembles between two proteins in structure-function studies that investigate the effect of mutations. A common measure to quantify differences in dynamics is the root mean square fluctuation (RMSF) about the average position of residues defined by C-atoms.

Such an automated process for univariate data is implemented to achieve this goal by merging the maximum entropy method with single order statistics and maximum likelihood. The only required properties of the random variables are that they are continuous and that they are, or can be approximated as, independent and identically distributed.

Systems approaches have great potential for application in predictive ecology. In this paper, we present a range of examples, where systems approaches are being developed and applied at a range of scales in the field of global change and biogeochemical cycling. Systems approaches range from Bayesian calibration techniques at plot scale, through data assimilation methods at regional to continental scales, to multi-disciplinary numerical model applications at country to global scales.
