Mapping aboveground carbon density in tropical forests can support CO2 emission monitoring and provide benefits for national resource management. Although LiDAR technology has been shown to be useful for assessing carbon density patterns, the accuracy and generality of calibrations of LiDAR-based aboveground carbon density (ACD) predictions with those obtained from field inventory techniques sh...
We examined patterns of habitat function (plant species richness), productivity (plant aboveground biomass and total C), and nutrient stocks (N and P in aboveground plant biomass and soil) in tidal marshes of the Satilla, Altamaha, and Ogeechee Estuaries in Georgia, USA. We worked at two sites within each salinity zone (fresh, brackish, and saline) in each estuary, sampling a transect from the ...
Background & Aim: Deanaie thyme (Thymus daenensis Celak.), a member of the Lamiaceae family. Thymus in one of the most important medicinal and aromatic plants that was used in pharmaceutical, food, cosmetics hygienic industries in most of developed countries. Recent studies have showed that thyme have strong antibacterial, antifungal, spasmolytic and antioxidant acti...
introduction: nitrogen is an essential element forplants and in combination withelements such as carbon, oxygen, hydrogen and sulfur results ineven more valuable materials such as amino acids, nucleic acids, alkaloids. hibiscus tea (hibiscus sabdariffa ) from malvaceaefamily is known by different names in different parts of the world. in iran it is calledthe maki tea, tea meccaorred tea.as an i...
Forests can partially offset greenhouse gas emissions and contribute to climate change mitigation, mainly through increases in live biomass. We quantified carbon (C) density in 20 managed longleaf pine (Pinus palustris Mill.) forests ranging in age from 5 to 118 years located across the southeastern United States and estimated above- and belowground C trajectories. Ecosystem C stock (all pools ...
In order to investigate the effect of putrescine and auxin (IBA) on rooting of semi-hardwood cuttings of the GN15 hybrid rootstocks, an experiment was conducted at the Flower Biology Laboratory of Faculty of Agriculture, Tabriz University in 1994. Cuttings were obtained from Sahand Gardening Research Station. This experiment was conducted in a completely randomized design with four replications...
the models oryza2000, swap and wofost simulate the growth and development of rice under conditions of potential production and water limitation. the models were evaluated against a data set of field experiments. the study was laid out in rcbd with three replications for one traditional landrace, hashemi, carried out in 2005 at the rice research institute of iran in rasht. the irrigation managem...
A field experiment was conducted at wondo genet Agriculture research center under irrigated condition to determine the effect of intra and inter-row spacing on growth and yield of Artemisia (Artemisia annua L.) during the two successive seasons of 2013 and 2014. Factorial combinations of four intra-rows (40, 60, 80, 100 cm) and four inter-row plant spacing’s (60, 80, 100, 120 cm) were laid out ...

When 2 Mha of Amazonian forests are disturbed by selective logging each year, more than 90 Tg of carbon (C) is emitted to the atmosphere. Emissions are then counterbalanced by forest regrowth. With an original modelling approach, calibrated on a network of 133 permanent forest plots (175 ha total) across Amazonia, we link regional differences in climate, soil and initial biomass with survivors'...
