متن کاملContrasting Responses of Marine and Freshwater Photosynthetic Organisms to UVB Radiation: A Meta-Analysis
Ultraviolet-B (UVB) radiation is a global stressor that has profound impacts on freshwater and marine ecosystems. However, an analysis of the patterns of sensitivity to UVB radiation across aquatic photosynthetic organisms has not yet been published. Here, we performed a meta-analysis on results reported in 214 studies compiled from the published literature to quantify and compare the magnitude...

متن کاملAlgal Pigment and Fossil Diatoms
The overarching aim of this paper is to investigate the lake ecosystem response to different 13 drivers over a long term period by a paleolimnological study in Lake Narlay (46°64N, 5°91E) located 14 in the Jura Mountains of France. It is a small, hard-water lake with a maximum water depth of 40 m 15 and extended anoxic condition of the bottom water. Previous results on sediments analysis have 1...
متن کاملThe effect of different concentrations of pyrene on photosynthetic pigment content and antioxidant enzymes activity in sunflower (Helianthus annuus)
World industrialization and population growth are the main reasons for the increase in environmental contamination with aromatic hydrocarbons. The presence of these compounds in the environment leads to a variety of stresses in plants and finally reduces their growth. Pyrene is one of the major toxic contaminants belonging to polycyclic aromatic hydrocarbons. Hence, in this research, the effect...
