Adı : Using Tree-Ring Signals And Numerical Model To Identify The Snow Avalanche Tracks In Kastamonu, Turkey
Açıklama : Many parts of our planet are exposed to natural disasters such as snow avalanches, floods and earthquakes. Detailed knowledge on these natural disasters is crucial for human safety. On December 25?26, 1992, two avalanches occurred at Kayaarkası-Kastamonu in northern Turkey. The first avalanche took place at night of 25?26 December and caused no damage. The second avalanche took place at morning of 26 December, killed four people and did damage to properties. The purpose of the present study is to determine the effects of the snow avalanches on tree rings and to investigate the boundaries and velocities of the avalanches using a numerical simulation model and the tree-ring data. Increment cores from 71 trees in the avalanche-impacted area and the control site were sampled to obtain individual standard chronologies. In the analyses, trees were grouped as (1) heavily damaged by the avalanche, showing a decrease in tree-ring widths since the event, (2) trees heavily damaged by the avalanche, showing an increase in tree-ring widths a couple of years later the event and (3) trees that were not damaged by the avalanche. In this study, one of the most important results is the precise determination of the temporal and spatial patterns of the undocumented avalanche (the first avalanche) event. Avalanches were numerically simulated using dynamical avalanche simulation software ELBA+. Comparison of the simulation model with tree-ring analysis revealed valuable results about the boundaries of the zone of influence of the avalanches.

Adı : Net Nitrogen Mineralization And Nitrification Rates In Different Land Uses: An In Situ Incubation
Açıklama : This study aimed to compare in situ net nitrogen mineralization and nitrification amounts in different land use types in northern Turkey (Karacakoy-Çatalca-Istanbul). The soils in the study area are loamy textured with generally slightly acidic (pHH2O between 4.29 -6.02) soil reaction. The vegetation types studied were pasture in abandoned agricultural lands, Cystus and Rubus sp. dominated shrubs at shrub land, and mixture of Quercus petrea, Q. cerris, Q. frainetto and Q. robur in the oak forest which was clear-cut. Thirteen sample plots were used to measure net mineralization and nitrification amounts during a month consisting from 3 recently abandoned agricultural lands (RAAL) (no application for 5 years), 3 old abandoned agricultural lands (OAAL) (no application for 20 years), 3 shrub lands (SL) and 4 oak forest lands (OFL). Sampling took place on April 24th and May 22nd in 2009. The 29 d net nitrogen mineralization amounts showed no differences among RAAL, OAAL and SL (0.223, 2.398 and 3.951 mg NH4+-N kg-1 for RAAL, OAAL and SL respectively), while OFL site produced more amount of net-nitrogen mineralization (10.976 mg NH4+-N kg-1) than the others (Tukey, p<0.05). The nitrification amounts also showed similar results with mineralization such as 0.604, 0.434, 0.499 and 2.602 mg NO3--N kg-1 for RAAL, OAAL, SL and OFL respectively (Tukey, p<0.05). The initial ammonium-N and nitrate-N concentration in the soils showed that for all land use types nitrate was mobile whereas ammonium was more stable mineral nitrogen form. In this study, the initial ammonium and nitrate amounts had a minor effect on the mineralization and nitrification. Amounts of organic carbon amounts were more important than total carbon and mineral nitrogen concentrations in affecting rates of N transformations. In conclusion, microclimatic conditions and differences in organic carbon are likely related to the differences in nitrogen transformation rates we measured.
