Forecasting temperate alpine glacier survival from accumulation zone observations
Forecasting temperate alpine glacier survival accumulation zone observations
2010/2/3
Temperate alpine glacier survival is dependent on the consistent presence of an accumulation zone. Frequent low accumulation area ratio values, below 30%, indicate the lack of a consistent accumulatio...
Spring molybdenum enrichment in scallop shells: a potential tracer of diatom productivity in temperate coastal environments (Brittany, NW France)
Spring molybdenum enrichment scallop shells diatom productivity temperate coastal environments
2010/1/21
Skeletal molybdenum/calcium ([Mo]/[Ca])shell ratios were examined in shells of the Great Scallop Pecten maximus collected in temperate coastal environments of Western Europe (42 to 49° N). These ratio...
Needle age-related and seasonal photosynthetic capacity variation is negligible for modelling yearly gas exchange of a sparse temperate Scots pine forest
Needle age-related and seasonal photosynthetic capacity variation a sparse temperate Scots pine forest
2010/1/21
In this study, we quantified the predictive accuracy loss involved with omitting photosynthetic capacity variation for a Scots pine (Pinus sylvestris L.) stand in Flanders, Belgium. Over the course of...
Sensitivity analysis of a wetland methane emission model based on temperate and arctic wetland sites
a wetland methane emission model temperate and arctic wetland sites
2010/1/21
Modelling of wetland CH4 fluxes using wetland soil emission models is used to determine the size of this natural source of CH4 emission on local to global scale. Most process models of CH4 formation a...
Response of temperate grasslands at different altitudes to simulated summer drought differed but scaled with annual precipitation
temperate grasslands simulated summer drought annual precipitation
2010/1/21
Water is an important resource for plant life. Since climate scenarios for Switzerland predict an average reduction of 20% in summer precipitation until 2070, understanding ecosystem responses to wate...
Environmental records from temperate glacier ice on Nevado Coropuna saddle, southern Peru
Environmental records temperate glacier ice Nevado Coropuna saddle
2010/1/28
We investigated past climate variability and the zonal short and long-range transport of air masses in tropical South America using chemical, isotopic and palynological signals from a 42 m-long ice co...
Effects of diurnal warming on soil respiration are not equal to the summed effects of day and night warming in a temperate steppe
diurnal warming soil respiration summed effects day and night warming temperate steppe
2010/1/20
The magnitude of daily minimum temperature increase is greater than that of daily maximum temperature increase under climate warming. This study was conducted to examine whether changes in soil respir...
Multiple quality tests for analysing CO2 fluxes in a beech temperate forest
Multiple quality tests CO2 fluxes beech temperate forest
2010/1/15
Eddy covariance (EC) measurements are widely used to estimate the amount of carbon sequestrated by terrestrial biomes. The decision to exclude an EC flux from a database (bad quality records, turbulen...
Leaf area controls on energy partitioning of a temperate mountain grassland
Leaf area controls energy partitioning temperate mountain grassland
2010/1/15
Using a six year data set of eddy covariance flux measurements of sensible and latent heat, soil heat flux, net radiation, above-ground phytomass and meteorological driving forces energy partitioning ...
Minor changes in soil organic carbon and charcoal concentrations detected in a temperate deciduous forest a year after an experimental slash-and-burn
Minor changes soil organic carbon charcoal concentrations temperate deciduous forest
2010/1/14
Anthropogenic fires affected the temperate deciduous forests of Central Europe over millennia. Biomass burning releases carbon to the atmosphere and produces charcoal, which potentially contributes to...
