Eubacterial communities in different soil macroaggregate environments and cropping systems
Different positions within soil macroaggregates, and macroaggregates of different sizes, have different chemical and physical properties which could affect microbial growth and interactions among taxa. The hypothesis that these soil aggregate fractions contain different eubacterial communities was tested using terminal restriction fragment length polymorphism (T-RFLP) of the 16S ribosomal gene....
متن کاملSpatial dynamics of Phlebotomus sand-fly ecological condition in response to climate change
Background: Changing the climatic pattern can lead to major changes in the geographical distribution of infectious diseases. The aim of this study was to investigate the effect of climate change on the favorable bio-climatological zone for leishmaniasis sand-fly living which is a vector of Leishmania in Iran. Materials and Methods: Data of the climatic factors affecting the biology of sandflies...
متن کاملAnalysis the Spatial Dynamics of Aloe Vera Medicinal Plants in Climate Change condition. Case: Hormozgan Province
Methodology: In this regard, the effective agro-ecological data in different phonological stages of Aloe Vera plant, including minimum and maximum temperature and precipitation as unstable factors, and elevation, slope, aspect, soil and salt domes, as stable elements in the assessment of susceptible areas Aloe vera cultivar was used. Using the Fuzzy Gama and Fuzzy Multi-criteria Decision-making...
متن کاملReproductive limits of a late-flowering high-mountain Mediterranean plant along an elevational climate gradient.
Mountain plants are particularly sensitive to climate warming because snowmelt timing exerts a direct control on their reproduction. Current warming is leading to earlier snowmelt dates and longer snow-free periods. Our hypothesis is that high-mountain Mediterranean plants are not able to take advantage of a lengthened snow-free period because this leads to longer drought that truncates the gro...
متن کاملSpatial variation and temporal stability of soil water in a snow-dominated, mountain catchment
Soil is a critical intermediary of water flux between precipitation and stream flow. Characterization of soil water content ( , m3 m 3) may be especially difficult in mountainous, snow-dominated catchments due to highly variable water inputs, topography, soils and vegetation. However, individual sites exhibit similar seasonal dynamics, suggesting that it may be possible to describe spatial vari...
