Surface Sediment Diatom Assemblages Response to Water Environment in Dongping Lake, North China
نویسندگان
چکیده
The relationship between the diatom taxa preserved in surface lake sediments and environmental variables Dongping Lake was explored using multivariate statistical methods. analysis showed that eutrophicated all seasons. Transparency, chlorophyll a (Chla) total phosphorus (TP) were dominant factors spring summer, NH4+-N chemical oxygen demand (COD) autumn winter. Sixteen genera 43 species of found sediments, Aulacoseira, Ulnaria, Cyclotella, Navicula Fragilaria. A redundancy (RDA) Monte Carlo permutation 20 test revealed COD, pH, TP, conductivity transparency significant influencing assemblage change, meaning distribution assemblages mostly influenced by nutrient composition, light intensity ion concentrations.

Quantifying Recent Ecological Changes in Remote Lakes of North America and Greenland Using Sediment Diatom Assemblages
BACKGROUND Although arctic lakes have responded sensitively to 20(th)-century climate change, it remains uncertain how these ecological transformations compare with alpine and montane-boreal counterparts over the same interval. Furthermore, it is unclear to what degree other forcings, including atmospheric deposition of anthropogenic reactive nitrogen (Nr), have participated in recent regime sh...
متن کاملDiatom-based interpretation of sediment banding in an urbanized lake
Sediment stratigraphy and diatom succession were studied in an 80.5-cm core taken from the deepest part of Third Sister Lake, a small kettle hole in a recently urbanized landscape of southeastern Michigan. Alternating light clay and dark organic bands documented sporadic inputs of clay from outside the basin during rain events, rather than annual laminations. Urban construction activity also di...
متن کاملAdsorption Behaviors of 17α-Ethinylestradiol in Sediment-Water System in Northern Taihu Lake, China
Adsorption behavior of 17α-ethinylestradiol (EE2) in northern Taihu Lake sediment was analyzed by using batch equilibrium experiment. Freundlich isotherm could describe the adsorption thermodynamic behavior of EE2 in sediment. Sediment organic matter (SOM) contents had important impacts on the adsorption capacity for EE2. The pH values also influenced the adsorption capacity for EE2. Increase o...
متن کاملSurface Water Quality Monitoring Site Optimization for Poyang Lake, the Largest Freshwater Lake in China
In this paper, we propose a coupled method to optimize the surface water quality monitoring sites for a huge freshwater lake based on field investigations, mathematical analysis, and numerical simulation tests. Poyang Lake, the largest freshwater lake in China, was selected as the research area. Based on the field investigated water quality data in the 5 years from 2008 to 2012, the water quali...
متن کاملPotentially Toxic Elements Contamination in Sediment, Surface and Pore water of Maharlu Saline Lake, South - West Iran
Maharlu Lake, located in the SW of Iran, has acted as a sink for various wastewater discharges in the last few decades. This study aimed at assessing potentially toxic elements (PTEs) distribution in sediment, surface and pore water samples of Maharlu Lake. To achieve that, the samples were collected from each compartment and the total concentration of PTEs (Al, Fe, Sc, Cr, Co, Ni, Zn, As, Sb, ...
