Degradation of mangrove tissues by arboreal termites (Nasutitermes acajutlae) and their role in the mangrove C cycle (Puerto Rico): Chemical characterization and organic matter provenance using bulk δ13C, C/N, alkaline CuO oxidation‐GC/MS, and solid‐state 13C NMR

  title={Degradation of mangrove tissues by arboreal termites (Nasutitermes acajutlae) and their role in the mangrove C cycle (Puerto Rico): Chemical characterization and organic matter provenance using bulk $\delta$13C, C/N, alkaline CuO oxidation‐GC/MS, and solid‐state 13C NMR},

Arboreal termites are wood decaying organisms that play an important role in the first stages of C cycling in mangrove systems. The chemical composition of Rhizophora mangle, Avicennia germinans, and Laguncularia racemosa leaf, stem, and pneumatophore tissues as well as associated sediments was compared to that of nests of the termite Nasutitermes acajutlae. Nests gave δ13C values of −26.1 to −27.2‰ (±0.1) and C/N of 43.3 (±2.0) to 98.6 (±16.2) which were similar to all stem and pneumatophores… 

The Potential of Mangrove-Derived Organic Matter in Sediments for Tracing Mangrove Development During the Holocene

The responses of mangroves to future climate change can be reconstructed from past mangrove dynamics using proxies preserved in sediments. The contributions of mangrove-derived organic matter (MOM)

Biodegraders of Large Woody Debris Across a Tidal Gradient in an Indonesian Mangrove Ecosystem

There has been limited research on the breakdown, recycling, and flux of carbon from large woody detritus (LWD) in mangrove forests. The breakdown of LWD is caused by guilds of terrestrial and marine

Vascular Plants Are Globally Significant Contributors to Marine Carbon Fluxes and Sinks.

It is shown that the fate of this detritus differs markedly from that of strictly marine origin, because the former contains lignocellulose-an energy-rich polymer complex of cellulose, hemicelluloses, and lignin that is resistant to enzymatic breakdown.

Nature of Volatile Organic Matter in Lake Sediments as a Reflection of Paleoclimate Changes Occurring at 4 ka in the Central Qaidam Basin

This study explores the paleoclimate changes around the 4 ka BP period in the central Qaidam Basin (QB), assessing the differences in spectral characteristics and organic composition of salt lake

Reliability of mangrove radiocarbon chronologies: A case study from Mahé, Seychelles

Mangrove sediments are valuable archives of paleoenvironmental and relative sea-level changes. The most widely applied method to obtaining chronologies of past changes in mangrove sediments is

Using isotope labeling to partition sources of CO2 efflux in newly established mangrove seedlings

There was a significant relationship between C isotope values of CO2 released at the sediment–air interface and both root respiration and sediment organic matter decomposition and these relative contributions of different components to overall and sediment CO2 efflux can be used in partitioning of the sources of overall resppiration and sediment C mineralization in establishing mangroves.



Biodegradation of oak (Quercus alba) wood during growth of the shiitake mushroom (Lentinula edodes): a molecular approach.

The chemical transformations that occur during growth of the shiitake mushroom (Lentinula edodes) on oak (Quercus alba) were investigated to improve mushroom cultivation and utilization of the spent

Isotopic and molecular distributions of biochemicals from fresh and buried Rhizophora mangle leaves†

The data support the theory that the fractionation of carbon and nitrogen occurs prior to or during uptake in dwarf and tall red mangrove trees, and could be powerful tools for predicting levels of nutrient limitation at Twin Cays.

Degradation of lignin in wheat straw during growth of the oyster mushroom (Pleurotus ostreatus) using off-line thermochemolysis with tetramethylammonium hydroxide and solid-state (13)C NMR.

There were increases in both guaiacyl and syringyl acid to aldehyde ratios with composting time, which showed that side-chain oxidation has been mediated by P. ostreatus.
