The development of cyanobacteria blooms is increasing concern in many lakes worldwide, and as a result, modeling their predictors vital for understanding where why they occur. In this study, we developed analyzed 640-lake data set that spans Canada 12 ecozones to identify the drivers biomass several key toxin- bloom-forming genera (Microcystis, Aphanizomenon, Dolichospermum). database consisted...

Engineering applications can be used to mitigate the adverse effects of soil compaction and amend compacted soils. Previous literature has highlighted beneficial interventions such as litter mulching incorporation on skid trails. However, little is known about effectiveness these alternatives in restoring forest quality after logging. The objective this study was properly elucidate above mentio...

Natural treefall gaps have a substantial role in maintaining soil and plant diversity old-growth forests. However, the amount of information on effects recovery physical chemical properties compacted soils is scarce. We tested hypothesis that natural accelerate restoration by enhancing biological microbial activity topsoil after period five years. Five years ground-based skidding operation Hyrc...

Nitrogen (N) addition (10 and 15 g N m −2 year −1 as dissolved $${\mathbf{N}\mathbf{H}}_{4}{\mathbf{N}\mathbf{O}}_{3}$$ ) significantly increased the CO 2 efflux from forest soil fine root biomass in a maple (Acer velutinum Bioss.) plantation. Following seasonal pattern, showed an exponential relationship with temperature. The effect of atmospheric deposition on CO2 is still unclear Hyrcanian f...

Kooch Y, SM Hosseini, Hojjati SM, Fallah A. 2013. Variability of soil physical indicators imposed by beech and hornbeam individual trees in a local scale. Biodiversitas 14: 25-30. The objective of our study was to determine if soil physical indicators could be related to the influence of the individual trees in stands of mixed species growing on steep slopes in the Hyrcanian forests of Iran.
