Fire influence on dynamics of above-ground phytomass in steppe plant communities in the Burtinskaya Steppe (Orenburg State Nature Reserve, Russia) [PDF]

Nature Conservation Research: Заповедная наука, 2019
People have significantly influenced on Orenburg region steppes by ploughing large parts of it, or by utilising other parts as mowed grasslands, pastures or abandoning crop production on the old abandoned fields. Frequent fires are another serious threat

Relation between the size of the above-ground and the underground phytomass of plant communities in the region of Gurwan-Turuu in Central Mongolia

Acta Societatis Botanicorum Poloniae, 2014
Results are presented of measurement of the above-ground and underground phytomass in six different plant communities on the area of the dry steppes of Central Mongolia. The relation was calculated between the above-ground and underground phytomass. This

Communities of Phragmites australis (Cav.) Trin.ex Steud. in the fluvial terrace of Lower Danube: their diversity and structure of the above-ground phytomass

Biologica Nyssana, 2017
Determination of stocks of aboveground phytomass of reed communities in Bulgaria is not well studied yet. This survey is the most detailed study on the stocks of the aboveground phytomass of the reed communities (Phragmites australis (Cav.) Trin.

Productivity, carbon sequestration and species diversity in virgin and secondary meadow steppes of the Bashkir Cis-Urals [PDF]

Scientific Reports
Steppes are of great importance for the global biogeochemical cycle and are characterized by high economic value. Carbon stocks in the soil of flat steppe landscapes are about one-fourth of the total carbon deposited in global soils.

Artificial Neural Network Modeling of High Arctic Phytomass Using Synthetic Aperture Radar and Multispectral Data

Remote Sensing, 2014
Vegetation in the Arctic is often sparse, spatially heterogeneous, and difficult to model. Synthetic Aperture Radar (SAR) has shown some promise in above-ground phytomass estimation at sub-arctic latitudes, but the utility of this type of data is not ...

Estimation of the above-ground phytomass dynamics in small-leaved linden plantations using multi-time Landsat images (forest case study from the Republic of Bashkortostan) [PDF]

E3S Web of Conferences
The study analyses the above-ground phytomass of smallleaved Linden plantations (Tilia cordata) using GIS and remote sensing data. As these data are crucial for forecasting the dynamics of stand development in the future, they are also essential for ...

The effects of nutrient additions on above-ground phytomass and its phosphorus and nitrogen contents of sand-plain lowland fynbos

South African Journal of Botany, 1989
The effects of the addition of 0,5g phosphorus m−2 [Ca3(PO4)2], 5g nitrogen m−2 (NH4NO3) and a mixture of all essential nutrients excluding N and P (M) on above-ground phytomass (biomass plus necromass) and nitrogen and phosphorus contents of the representative plant growth forms of sand-plain lowland fynbos vegetation at Pella, south-western Cape ...
