Oak decline in the Boston Mountains, Arkansas, USA: Spatial and temporal patterns under two fire regimes
A spatially explicit forest succession and disturbance model is used to delineate the extent and dispersion of oak decline under two fire regimes over a 150-year period. The objectives of this study are to delineate potential current and future oak decline areas using species composition and age structure data in combination with ecological land types, and to investigate how relatively frequent...
متن کاملStudy of spatial and temporal rain and drought patterns in the south of Iran using TRMM
Droughts are one of the most damaging climatic phenomena, and the most complex natural hazard which affects the economy, agriculture, public health and environment in large areas. The aim of this study is to compare drought indicators derived from tropical rainfall measuring mission (TRMM) data in the south of Iran. Also the TRMM rainfall was considered, so as to investigate changes in the rai...
متن کاملبررسی تاثیر چرای دام بر گروه های عملکردی گیاهان در منطقه بهارکیش قوچان (plant functional types)
چرای دامهای اهلی و خشکسالی در ایران، به عنوان مهمترین عوامل در تغییر و شکلگیری پوشش گیاهی مطرح هستند. عوامل زیستی و غیر زیستی باعث تغییرات قابل پیشبینی در صفات گیاهی در پیش- (plant functional types (pfts)) امتداد گرادیان محیطی میشوند. گروههای عملکردی گیاهی بینی تغییرات در فرایندهای اکوسیستم را مستقیماً از طریق تغییرات منعکس شده در ترکیب گونههای گیاهی در پاسخ به تغییرات محیطی امکانپذیر میکند....
15 صفحه اولSimulating the effects of different fire regimes on plant functional groups in Southern California
A spatially explicit landscape model of disturbance and vegetation succession, LANDIS, was used to examine the effect of fire regime on landscape patterns of functional group dominance in the shrublands and forests of the southern California foothills and mountains. Three model treatments, frequent (35 year), moderate (70 year), and infrequent (1050 year) fire cycles, were applied to the landsc...
متن کاملSpatial and temporal patterns of benthic macrofauna in Gorgan Bay, south Caspian Sea, Iran
We quantified the distribution, abundance and assemblage structure of macrofauna at 22 stations in Gorgan bay, seasonally in 2012-2013. Also, depth, temperature, salinity, DO, TOM and sediment particle size were measured in each station. The highest concentration of TOM was measured near the western littoral zone (10.22) while the mouth part and north-eastern area was characterized by the lowes...
