Climatic and Environmental Reconstruction Based on Stable Isotopes of Parishan Lake (Iran)
The isotopic documents of lake deposition are suitable potential means for studyingthe intercontinental, environmental and climatic conditions. In order to study theenvironmental and climatic conditions of Parishan area in Fars province in Holocene, a Corewas taken with the length of 2m from the Parishan lake sediment. From this core, kernel timeseries was provided from documents of carbon and ...
متن کاملSeasonal changes in some physiological and biochemical responses of six groundcover plants
Landscape groundcover plants are a diverse group of trailing or spreading species that naturally form continuous soil coverage.Ground cover plants that were used in this study consisted of vegetative propagules of: Vinca minor L. ٬Variegatum’, Vinca minor L. ٬Green’, Oxalis brasiliensis G. Lodd, Trifolium repens L., Phyla nodiflora L. and Frankenia thymifolia Desf. The aim of this study was to ...
متن کاملResponse of conifers to UV-B and climate in mountain areas
The present study was focused to examine the combined effects of climate and ultraviolet-B radiation on conifer tree-ring density. Statistical methods were employed to extract tree responses in annual ring density and to identify functional relationship in trees when the level of ultraviolet-B radiation changes regardless of climate variations. In this study, the consideration was given to the ...
متن کاملMultiple physiological responses to multiple environmental challenges: an individual approach.
The injection of anthropogenically-produced CO2 into the atmosphere will lead to an increase in temperature and a decrease in pH at the surface of the oceans by 2100. Marine intertidal organisms possess the ability to cope in the short term with environmental fluctuations exceeding predicted values. However, how they will cope with chronic exposure to elevated temperature and pCO2 is virtually ...
متن کاملIntraspecific response of colonial ascidians to variable salinity stress in an era of global change
Extreme or seasonal climatic events can lead to abrupt changes in environmental conditions. These events can produce a range of organismal responses that may help to protect local-scale populations against changes in climate. Empirical studies examining intraspecific variation in reproductive and physiological responses to varying durations of environmental stress are rare. We performed laborat...
