pollen analysis in peat bogs and colluvial layersIn climatically sensitive regions such as the Northern Alps, changes in climate and land use have a strong impact on landscapes, vegetation, animals and humans. Multidisciplinary investigations in the high St Antönien Valley (Switzerland) at 1400—...
Reconstruction of the rates at which lands were cleared for agriculture, abandoned, harvested for wood, and burned from historical data for the period 1700-1990; Use of data in a terrestrial carbon model to calculate the annual changes in the amount of carbon stored in terrestrial ecosystems, ...
We analysed a terrestrial assemblage database of unprecedented geographic and taxonomic coverage to quantify local biodiversity responses to land use and related changes. Here we show that in the worst-affected habitats, these pressures reduce within-sample species richness by an average of 76.5%, ...
Concerning T2, there were important transitions registered as the extensive reduction of peatbogs and high-Andean wetlands increasing natural grasslands. Table 1 Estimated area (km2) of each type of changes and land-change dynamics occurred from 2000 to 2013 in the study area. Full size table ...
Conceptual figure of the 36 sample plots (colored circles) comprising each possible combination of hypothesized landscape drivers: soil texture (coarse, peat, or fine); canopy age (building or mature); hillslope position (low, medium, or high); and aspect (north or south). We installed weather...

Strange Things Turn Up In Peat Moss Bogs Photo: PBS, “Mummies 101”; 400BC-400AD Most mosses disperse their spores through wind. Spores are released through the peristome (often sensitive to humidity!) Weird Exceptions: Dung mosses produce nasty odors that attract flies. Their spores are stic...

“Biodiversity… is declining faster than at any time in human history”, with projected continuing declines3. However, there is continuing debate. For example, although major land-use changes do reduce the number of species per unit area1, analyses of time-series data (repeatedly sampled ...
(Table1), all of which show sensible heat fluxes of equal or greater magnitude than latent heat fluxes21,45. Boreal peat bogs are characterized by high moss coverage lacking stomatal control of water vapor exchange with the atmosphere46,47. Future changes in peatland cover depend on complex ...
