wild almond (amygdalus scoparia) is one of the most important species that provides a variety of ecological functions in the zagros forest ecosystem. in this study, we investigated the effects of some seed treatments on the survival and growth of amygdalus scoparia after seed planting at different aspects and elevations under natural conditions. the seed pretreatments consisted in soaking them ...

Land shortage for burials is one of many issues that emerge out of accelerated urban growth in most developing Asian cities, including Kuala Lumpur. Despite actions taken by the federal government and local authorities in addressing this issue, there is no strategic solution being formulated. Apart from making provisions for land to be developed as new cemeteries, the future plan is merely to a...

The burial of organic carbon in marine sediments removes carbon dioxide from the ocean-atmosphere pool, provides energy to the deep biosphere, and on geological timescales drives the oxygenation of the atmosphere. Here we quantify natural variations in the burial of organic carbon in deep-sea sediments over the last glacial cycle. Using a new data compilation of hundreds of sediment cores, we s...

immersion in cold water causes bradycardia.4 These effects may occur during burial in an avalanche of snow. Hypothermia often.occurs in burial in an avalanche. The face is often the only area unprotected by clothing and in direct contact with the snow, which may be important as it is the face that triggers the diving reflex. This is unlike immersion in cold water, when cooling is more uniform. ...

The degradation of sedimentary particulate organic carbon (POC) is a key carbon cycle process that fuels the deep subseafloor biosphere. The reactivity of POC is expected to decrease with increasing sediment age, severely restricting the energy available to microorganisms. Conversely, increasing temperatures during burial have been proposed to stimulate POC degradation, possibly supplying signi...

The sulfur cycle influences the respiration of sedimentary organic matter, the oxidation state of the atmosphere and oceans, and the composition of seawater. However, the factors governing the major sulfur fluxes between seawater and sedimentary reservoirs remain incompletely understood. Using macrostratigraphic data, we quantified sulfate evaporite burial fluxes through Phanerozoic time. Appro...
