Quantifying the time lag between organic matter production and export in the surface ocean: Implications for estimates of export efficiency
Sign Up to like & getrecommendations! Published in 2017 at "Geophysical Research Letters"
DOI: 10.1002/2016gl070875
Abstract: The ocean's potential to export carbon to depth partly depends on the fraction of primary production (PP) sinking out of the euphotic zone (i.e., the e-ratio). Measurements of PP and export flux are often performed… read more here.

DOI: 10.1002/2016gl072260
Abstract: Fjords have recently been recognized as “hotspots” of carbon burial. In this study, we investigated organic carbon (OC) and biomarker radiocarbon values in fjord sediments from New Zealand. Our results showed that OC was mostly… read more here.

DOI: 10.1002/2017jg004312
Abstract: Peatlands can accumulate organic matter into long‐term carbon (C) storage within the soil profile. This study used solid‐state 13C nuclear magnetic resonance (13C‐NMR) to investigate the transit of organic C through a peatland ecosystem to… read more here.

DOI: 10.1002/ece3.9433
Abstract: Abstract The breakdown of allochthonous organic matter, is a central step in nutrient cycling in stream ecosystems. There is concern that increased temperatures from climate change will alter the breakdown rate of organic matter, with… read more here.

DOI: 10.1002/ecy.3328
Abstract: Fungi and bacteria are the two principal microbial groups in soil, responsible for the breakdown of organic matter (OM). The relative contribution of fungi and bacteria to decomposition is thought to impact biogeochemical cycling at… read more here.

Riverine aquatic plants trap propagules and fine sediment: Implications for ecosystem engineering and management under contrasting land uses
Sign Up to like & getrecommendations! Published in 2024 at "Earth Surface Processes and Landforms"
DOI: 10.1002/esp.5844
Abstract: Plants in streams act as physical ecosystem engineers, both influencing and responding to hydrogeomorphic processes such as fine sediment retention. Instream vegetation may also influence propagule dispersal and retention, shaping plant community dynamics. These plant‐sediment… read more here.

DOI: 10.1002/etc.5577
Abstract: The decomposition of allochthonous organic matter, such as leaves, is a crucial ecosystem process in low-order streams. Microbial communities, including fungi and bacteria, colonise allochthonous organic material, break up large molecules and increase the nutritional… read more here.

DOI: 10.1002/lno.10453
Abstract: Effects of land use on hydrology, organic matter sources, and processing may be proportionately greater in tidal creeks than large estuaries, yet tidal creek systems have been undervalued in assessments of emerging effects of anthropogenic… read more here.
