Six million years ago atmospheric shifts grassland mammals
2019/10/30
Six million years ago, grass-eating mammals became more diverse in South America. Shifts in tropical atmospheric circulation known as Hadley circulation led to changes in climate and vegetation, espec...
RESPONSE OF ALPINE GRASSLAND VEGETATION PHENOLOGY TO SNOW ACCUMULATION AND MELT IN NAMCO BASIN
Vegetation Greening Vegetation Growth Length Snow Cover Fraction Trend Analysis Relationship Namco Basin
2018/5/11
Snow/ice accumulation and melt, as a vital part of hydrological processes, is close related with vegetation activities. Taking Namco basin for example, based on multisource remote sensing data and the...
GRASSLAND NPP MONITORING BASED ON MULTI-SOURCE REMOTE SENSING DATA FUSION
Multi-source remote sensing Data fusion Net primary productivity Carnegie-Ames-Stanford Approach model
2018/5/11
Vegetation is an important part of the terrestrial ecosystem. It plays an important role in the energy and material exchange of the ground-atmosphere system and is a key part of the global carbon cycl...
EVALUATION OF RGB-BASED VEGETATION INDICES FROM UAV IMAGERY TO ESTIMATE FORAGE YIELD IN GRASSLAND
RGB vegetation indices unmanned aerial vehicle biomass yield grassland pasture
2018/5/15
Monitoring forage yield throughout the growing season is of key importance to support management decisions on grasslands/pastures. Especially on intensely managed grasslands, where nitrogen fertilizer...
Ancient bones point to shifting grassland species as climate changes
Ancient bones shifting grassland species climate changes
2016/4/13
More rainfall during the growing season may have led to one of the most significant changes in the Earth’s vegetation in the distant past, and similar climate changes could affect the distribution of ...
Activity time budget patterns of sheep and goats co-grazing on semi-natural species-rich dry grassland
animal behaviour activity pattern small ruminant mixed pasture semi-natural grassland
2015/6/24
Activity time budget patterns and grazing response to sward and environmental conditions were investigated for paddocks of sheep and goats co-grazing for conservation purposes on a semi-natural specie...
Do grazer hair and faeces reflect the carbon isotope composition of semi-arid C3/C4 grassland?
Community composition Grazing pressure Ecosystem reconstruction Pasture Trophic shift Digestibility Selectivity Discrimination Diet Inner Mongolia
2015/2/4
The carbon isotope composition ( d13C) of C3/C4 mixed grassland is reflected in the d13C of diet, hair or faeces of grazers, if 13C discrimination (13 D) between grassland vegetation and these tissues...
Ecosystem stability and compensatory effects in the Inner Mongolia grassland
Ecosystem stability compensatory effects Inner Mongolia grassland
2015/2/4
Numerous studies have suggested that biodiversity reduces variability in ecosystem productivity through compensatory effects1–6; that is, a species increases in its abundance in response to the reduct...
Short-term changes in soil Munsell colour value, organic matter content and soil water repellency after a spring grassland fire in Lithuania
Short-term changes soil Munsell colour value organic matter content soil water repellency spring grassland fire Lithuania
2015/1/6
Fire is a natural phenomenon with important implications on soil properties. The degree of this impact depends upon fire severity, the ecosystem affected, topography of the burned area and post-fire m...
Grassland fire effect on soil organic carbon reservoirs in a semiarid environment
effect on soil organic carbon emiarid environment
2015/1/5
The aim of this work was to investigate the effect of an experimental fire used for grassland management
on soil organic carbon (SOC) stocks. The study was carried
out on Hyparrhenia hirta (L....
Spatial models for monitoring the spatio-temporal evolution of ashes after fire – a case study of a burnt grassland in Lithuania
The thickness of the ash soil erosion unscheduled fire ash thickness measurement
2015/1/5
Ash thickness is a key variable in the protection of soil against erosion agents after planned and unplanned fires. Ash thickness measurements were conducted along two transects (flat and sloping area...
