Modeling the response of tropical highland herbaceous grassland species to climate change: The case of the Arsi mountains of Ethiopia por Mekasha, A., Nigatu, L., Tesfaye, K., Duncan, Alan J.

“…Global warming is forcing plant and animal species to respond either through pole-ward or upslope migration to adjust to temperature increases, and grassland communities are not an exception to this phenomenon. …”

Biomass, carbon and nutrient storage for dominant grasses of cold temperate steppe grasslands in southern Patagonia, Argentina por Peri, Pablo Luis, Lasagno, Romina Gisele

“…The aim was to quantify the amount of biomass, carbon and nutrients in both above- and belowground components for four dominant grasses in grasslands steppe. We analyzed biomass, carbon and nutrients (N, P, K, Ca, Mg and S) of each dominant grass species corresponding to different sizes and separated in components (green and senesced leaves, pseudostem, and fine and coarse roots). …”

Make fallow great again : a study of the substitution between wheat production and fallow and temporary grassland por Wästljung, David

“…This study aims to research the economic conditions on which it is possible to produce wheat on fallow or temporary grasslands. By using this land, agricultural markets are not threatened by any food deficits and there will be no cause for additional production. …”

Impact of management intensity on the plant diversity and soil carbon of grasslands in different agro-climatic regions of Sweden por Blomberg, Hugo
