Morphometry-Driven Divergence in Decadal Changes of Sediment Property in Floodplain Water Bodies

چکیده
Sediments are potentially the internal source that supply nutrients to water in lentic semi-lentic ecosystems. The understanding of factors cause temporal changes sediment properties is critical for management. This study investigated spatial variations and relation their controlling bodies Ishikari River, Northern Japan. Sediment data 29 were measured twice (around 2005 2019) properties, compared using Generalized Linear Mixed Models (GLMMs). including catchment morphometry examined by partial least square (PLS) regression. Our results showed change over decades was largely driven morphometry, while land use played a relatively minor role those changes. rate organic matter (OM) differed among depending on morphometry. small shallow provided suitable habitat macrophytes led OM deposits, resulting an increase total nitrogen (TN) ratio time. consequences these important management biodiversity conservation.

Pollution Studies of Some Water Bodies in Lagos, Nigeria
Over the years, there has been an obvious pollution problem in Lagos area, Nigeria with high population of over eleven million and the near absence of waste management infrastructures. Concentrations of some pollution parameters and trace elements (temperature, pH, salinity, SO42-, NO3-, PO43-, F-, DO, BOD, COD and coliform, Cr, Co, Ni, Ag, Cd and Pb) were determined from water bodies of Isolo ...

Decadal changes in Pacific carbon
[1] This paper uses the extended multiple linear regression (eMLR) technique to investigate changes over the last decade in dissolved inorganic carbon (DIC) inventories on a meridional line (P16 along 152 W) up the central Pacific and on a zonal line (P02 along 30 N) across the North Pacific. Maximum changes in the total DIC concentrations along P02 are 15–20 mmol kg 1 over 10 years, somewhat h...
