Determination and recognition of relative distribution of chemical forms of each element and their relationship with physical, chemical and soil clay minerals can help researchers to manage soil fertility better. This research attempted to recognize chemical fractions of zinc (Zn) and copper (Cu) in some surface and subsurface soil samples of Kohgiluyeh and Boyer-Ahmad province and their relati...

Water is a key output of southern forests and is critical to other processes, functions, and values of forest ecosystems. This chapter synthesizes published literature about the effects of forest management practices on water quantity and water quality across the Southern United States region. We evaluate the influences of forest management at different temporal and spatial scales, and we recog...

The resolution was increased to experimental 2.8...

We used dendrochronological methods and remnant fire-scarred red pines (Pinus resinosa Ait.) to reconstruct historical fire regime characteristics relate these findings past climate, human land use changes, vegetation for a landscape in northern Minnesota, USA. A total of 314 scars were dated, representing 56 unique events from 1565 1967. In the period prior exclusion (1535–1935), intervals ran...

to modeling of suitability iranian oak site to establish coppice regenerations, chahartagh forest reserve, ardal region, chaharmehal and bakhtiari province, southern zagros forest, and southwest iranian state was selected. to modeling suitability iranian oak used the physiographic element, soil depth, climatology and distance from village selected. to this study used the raster formats by pixel...
