Faster than expected: Release of nitrogen and phosphorus from decomposing wood

Baptiste Joseph Wijas, William K Cornwell, Jeff R Powell, et al.

● Deadwood represents globally important carbon, nitrogen, and phosphorus pools. Current wood nutrient dynamics models are extensions of those developed for leaf litter decomposition. However, tissue structure and dominant decomposers differ between deadwood and litter, and recent evidence suggests that decomposer stoichiometry in combination with litter quality may affect nutrient [...]

A rapidly expanding house of cards: the silent loss of cell physiology hampers marine biosciences

Perspective: An ongoing loss of expertise on the biochemistry and physiology of marine organisms hampers our understanding of biological mechanisms upon rapidly growing “-omics” approaches reply -ultimately affecting our ability to predict organismal responses to climate change.

Computational Modeling and Evolutionary Implications of Biochemical Reactions in Bacterial Microcompartments

Bacterial microcompartments (BMCs) are protein-encapsulated compartments found across at least 23 bacterial phyla. BMCs contain a variety of metabolic processes that share the commonality of toxic or volatile intermediates, oxygen-sensitive enzymes and cofactors, or increased substrate concentration for magnified reaction rates. These compartmentalized reactions have been computationally modeled [...]

Ecosystem services of a functionally diverse riparian zone in the Amazon–Cerrado agricultural frontier

The ecological services provided by protected riparian zones in human-altered landscapes are widely acknowledged, yet little is known about them. In this study, we assess ecosystem properties that a protected riparian zone maintains in contrast to environmental changes in its surroundings caused by agro-industrial activities in the northwestern fringe of the Brazilian Cerrado on the [...]
