in order to investigate the effects of management models on the diversity of wooden species, forests of third series of shiler, the first division mehrbanrud watershed and third and fourth series of eight division of behshahr – neka townships were studied with participatory and governmental management respectively. the diversity of the wooden species have been evaluated by diversity parametric...
Compacted soil has lower water infiltration and hydraulic conductivity, which contributes to increased runoff and erosion on slopes. The aim of the present study was to assess runoff and sediment on three skidding trail longitudinal gradients (15%, 25%, and 35%) and different levels of machine traffic (low, medium, and high), over a two-year period following the impact in the Hyrcanian forest, ...
Abstract Cave biodiversity and ecosystems are underexplored. To guide conservation needs for visitor management, we surveyed the 2,158 m long Danial in northern Iran vertebrate fauna. We identified four mammalian two amphibian species cave: greater horseshoe bat Rhinolophus ferrumequinum , Blasius's blasii lesser mouse-eared myotis Myotis blythii Hyrcanian field mouse Apodemus hyrcanicus wood f...
Trees with sufficient nutrition are known to allocate carbon preferentially to aboveground plant parts. Our global study of 49 forests revealed an even more fundamental carbon allocation response to nutrient availability: forests with high-nutrient availability use 58 ± 3% (mean ± SE; 17 forests) of their photosynthates for plant biomass production (BP), while forests with low-nutrient availabi...
