Time-Lag Effect of Climate Conditions on Vegetation Productivity in a Temperate Forest–Grassland Ecotone
time-lag effect vegetation type soil texture spatial and temporal heterogeneity
2023/12/1
Climate conditions can significantly alter the vegetation net primary productivity (NPP) in many of Earth’s ecosystems, although specifics of NPP–climate condition interactions, especially time-lag re...
Comparison of Natural Regeneration in Natural Grassland and Pine Plantations across an Elevational Gradient in the Páramo Ecosystem of Southern Ecuador
Andes species richness vegetation assemblage plant cover natural grassland soil properties
2024/2/29
During the 1980s, reforestation programs using exotic species (Pinus spp.) were established in the páramo ecosystem of Ecuador. The aims of this study were: (1) to compare the natural regeneration bet...

Impact of Arable Land to Grassland Conversion on the Vegetation-period Water Balance of a Small Agricultural Catchment (Němčicky Stream)
hydrological extremes hydrological modelling land use change water balance
2015/3/2
This paper presents results of decadal (10-day) water balance simulations for the vegetation periods (April to October) of 2001 (normal year), 2002 (wet year) and 2003 (dry year) in the Němčicky ...
C4 abundance in an Inner Mongolia grassland system is driven by temperature–moisture interaction, not grazing pressure
C4 abundance Inner Mongolia grassland system temperature–moisture interaction not grazing pressure
2015/2/4
Global warming and CO2 rise is expected to change the balance of C3 and C4 plants in grassland vegetation, but disturbance,including grazing, could also affect C3/C4 community structure. We used a six...
Seasonally dependent impacts of grazing on soil nitrogen mineralization and linkages to ecosystem functioning in Inner Mongolia grassland
Typical steppe Grazing intensity Season Soil inorganic N pools Net N mineralization Soil temperature and moisture BiomassN content Nitrogen use efficiency
2015/2/4
Previous studies have suggested grazing may alter nitrogen (N) cycling of grasslands by accelerating or decelerating soil net N mineralization. The important mechanisms controlling these fluxes remain...
