چکیده مقاله:

Since Renaissance, the natural ecosystems have fallen into a complete state ofdisarray due to the rise in the amount of carbon dioxide. Soil, the unsparing stuff, is one of themajor sources of carbon storage, and plays a paramount role in the global equilibrium ofcarbon as well as carbon sequestration. Given that Iran is benefiting from vast steppes, therate of carbon sequestration in them deserves attention. In order to estimate the soil carbonsequestration, the Saveh Rudshur steppes were selected and placed into three treatments:long-term exclosure, medium-term exclosure and grazing rangelands. The soil sampling wasconducted at the depth of 0-30 cm under the plants and between the plants. As many as 60 soilsamples on each area and 180 soil samples in total were taken. The sampled soils were driedout in the open air and sifted through a sieve of 2mm meshes in the laboratory. The soilorganic carbon was measured using the Walkley-Black method. The findings indicated thatthere was a significant difference between the amount of the soil organic carbon under theplants and the carbon between the plants on each area separately (P

Phytomass and carbon storage in the Stipa tenacissima steppes of the Baza basin, Andalusia, Spain

Above-ground perennial phytomass of Andalusian alfa grass steppes (7755·6 ± 1482 kg of dry matter ha (95% C.I.)) is clearly higher than phytomass density measured today in most alfa grass communities of the Maghreb because of low or inexistant present-day human-induced alterations and relatively favourable annual precipitation (370 mm) existing in these Spanish steppes. Total carbon storage mea...

Bacterial Diversity in Biological Soil Crusts from Extrazonal Mountain Dry Steppes in Northern Mongolia

Biological Soil Crusts (BSCs), consisting of prokaryotes, microalgae, lichens, mosses and eventually small vascular plants, cover wide areas in arid and semi-arid environments. In the present study, the microbial diversity of these crusts was explored at extrazonal mountain steppe sites in the western Khentej (Northern Mongolia). At the study site the Siberian taiga borders on the Mongolian-Dau...

Estimation of biomass, carbon stocks and soil sequestration of Gowatr mangrove forests, Gulf of Oman

The mangrove forest ecosystem is known to possess a variety of ecosystem services, including high rates of carbon sequestration, storage and mitigating climate change through reduced deforestation. This study was carried out in the mangrove forests of Gowatr Bay, Gulf of Oman during 2017-18 to quantify biomass and carbon stocks of all components of this forest, including live and dead trees, so...

Indices based on surface indicators predict soil functioning in Mediterranean semi-arid steppes

Methodologies based on indicators occupy a prevalent place when assessing ecosystem functioning and monitoring desertification processes because they are affordable yet do not compromise accuracy. The landscape function analysis (LFA), developed in Australia by David Tongway (CSIRO), uses soil surface indicators to assess the condition of a given ecosystem by producing three numerical indices (...
