Near-future levels of ocean acidification do not affect sperm motility and fertilization kinetics in the oyster Crassostrea gigas
Near-future levels ocean acidification sperm motility and fertilization kinetics the oyster Crassostrea gigas
2010/1/21
An increasing number of studies are now reporting the effects of ocean acidification on a broad range of marine species, processes and systems. Many of these are investigating the sensitive early life...
Effects of N and P fertilization on the greenhouse gas exchange in two northern peatlands with contrasting N deposition rates
N and P fertilization greenhouse gas exchange northern peatlands N deposition rates
2010/1/21
Peatlands are important ecosystems in the context of biospheric feedback to climate change, due to the large storage of organic C in peatland soils. Nitrogen deposition and increased nutrient availabi...
Impact of atmospheric and terrestrial CO2 feedbacks on fertilization-induced marine carbon uptake
atmospheric and terrestrial CO2 feedbacks fertilization-induced marine carbon uptake
2010/1/20
The sensitivity of oceanic CO2 uptake to alterations in the marine biological carbon pump, such as brought about by natural or purposeful ocean fertilization, has repeatedly been investigated by studi...
Mineral fertilization did not affect decay of old lignin and SOC in a 13C-labeled arable soil over 36 years
Mineral fertilization decay lignin SOC 13C-labeled arable soil
2010/1/20
Retardation of soil organic carbon (SOC) decay after nitrogen addition to litter or soil has been suggested in several recent studies and has been attributed to a retardation in lignin decay. With our...
Ammonia fluxes in relation to cutting and fertilization of an intensively managed grassland derived from an inter-comparison of gradient measurements
Ammonia fluxes cutting fertilization grassland inter-comparison gradient measurements
2010/1/20
Quantification of ammonia (NH3) land-atmosphere exchange is required for atmospheric modelling and assessment of nitrogen deposition, yet flux measurement methods remain highly uncertain. To address t...
The impact on atmospheric CO2 of iron fertilization induced changes in the ocean's biological pump
atmospheric CO2 iron fertilization ocean's biological pump
2010/1/15
Using numerical simulations, we quantify the impact of changes in the ocean's biological pump on the air-sea balance of CO2 by fertilizing a small surface patch in the high-nutrient, low-chlorophyll r...
Effects of free atmospheric CO2 enrichment (FACE),N fertilization and poplar genotype on the physical protection of carbon in the mineral soil of a polar plantation after five years
free atmospheric CO2 enrichment N fertilization poplar genotype physical protection
2010/1/13
Free air CO2 enrichment (FACE) experiments in aggrading forests and plantations have demonstrated significant increases in net primary production (NPP) and C storage in forest vegetation. The extra C ...
Thermal stability responses of soil organic matter to long-term fertilization practices
Thermal stability responses soil organic matter long-term fertilization practices
2010/1/13
We used differential scanning calorimetry (DSC) to infer thermal properties of soil organic matter (SOM) in the static fertilization experiment in Bad Lauchstädt, Germany, which has been establis...
