increasing level of carbon dioxide co2 due to industrial activity is primarily cause of global warming. planting artoplex lentiformis can help to reduce atmospheric co2 buildup partly replacing use of fuels and by carbon storage. the objective of this study was to determine the effects of row spacing on carbon storage. a split- plot design with three replications included three row spacing (2×2...

the effects of different grazing intensities on the above and underground biomass of twospecies festucaovina l. and alopecurustextilisboiss. in the north sabalan rangelands (in shabil) were investigated. sampling on the light, medium and heavy grazing intensities in the flowering stage (the second half of june 2013) were performed. initially, from a 90-meter transects perpendicular to the slope...

In the Paranapanema River mouth, Jurumirim Reservoir (23 degrees 27'-23 degrees 29'S and 48 degrees 39'-48 degrees 36'W, SP, Brazil), the biomass of E. polystachya was monthly determined with eight quadrats of 0.25 m2 from August 1993 to July 1994. The seasonal variation in biomass was unimodal, with greater biomass from November 1993 to April 1994. The average biomass was 1,933.7 +/- 479.5 gDW...

The atmospheric boundary layer and lower free atmosphere, or aerosphere, is increasingly important for human transportation, communication, environmental monitoring, and energy production. The impacts of anthropogenic encroachment into aerial habitats are not well understood. Insectivorous birds and bats are inherently valuable components of biodiversity and play an integral role in aerial trop...

The aerial carbon balance of a 9-year-old hinoki cypress (Chamaecyparis obtusa (Sieb. et Zucc.) Endl.) stand with an aerial biomass of 24.6 Mg(DW) ha(-1) was studied over a 1-year period. Various components that constitute gross production were measured on the basis of the summation method. Respiration of the aerial parts of six sample trees was measured at monthly intervals by an enclosed stan...

The research was based on a pot experiment, in which the response of eight species of crops to soil contamination with fluorine was investigated. In parallel, some inactivating substances were tested in terms of their potential use for the neutralization of the harmful influence of fluorine on plants. The response of crops to soil contamination with fluorine was assessed according to the volume...

Climate change is one of the most important challenges in sustainable development which has negative effect on terrestrial and aquatic ecosystem. The lead factor of this phenomenon is Co2 accumulation in atmosphere. One of the suitable ways of facing the mentioned issue is carbon sequestration in plant biomass and soil as a simple as well as inexpensive refined way in rangelands. With respect t...
