ABSTRACT Investigating the differences among plant functional types (PFTs) and their responses to N deposition is crucial for predicting carbon nutrient cycles improving forest management strategies. Our research aimed examine decomposition rates loss of leaf litter fine roots from ancient recently evolved species response deposition. We hypothesized that (1) leaves tree decomposes slower than those due higher C:N ratios structural compound content; (2) effect addition on differs across different stages influenced by associated PFT; (3) morphology substrate quality are key predictors both species. Field experiments were conducted with under control N‐addition treatment (10 g·m −2 ·a −1 ), focusing three The rate constants ( k values) lower species, values 1.01 1.68 conditions, 1.07 1.08 addition. For roots, had only (1.05 1.40), whereas no significant observed between conditions. Furthermore, residual in was compared controls, while such distinct patterns this study provide valuable insights into complexity deposition, highlighting importance considering PFTs organ ecosystem responses.

Manganese (Mn) is a possibly critical yet poorly understood element controlling soil carbon (C) stocks. In temperate forests, Mn availability correlates strongly with organic C decay, but we know little about its role in matter decomposition most terrestrial environments. this study, evaluate grassland dynamics along rainfall gradient Hawaii. We measured Mn, matter, and microbial enzyme activities the to relationships among oxidation state, chemical/biological reactivity, turnover. Neither abundance nor state are strong predictors of instability gradient. also used an incubation experiment investigate how dissolved CO2 release from respond increased bioavailability. found that did not correlate instability; additions corresponded lower fluxes soils than deionized water. may predict stability as well previously thought.
