Nutrient enrichment and trace element accumulation in sediments caused by waterbird colonies at a Mediterranean semiarid floodplain

چکیده
Waterfowl are vectors of nutrients, metals, and other pollutants (i.e. PCBs microorganisms) on wetlands water bodies, especially when bird population density is high, e.g., in nesting, roosting or breeding periods. This work reports the effects caused by increase pairs herons cormorants between 2010 2014 sediments an eutrophic Mediterranean wetland belonging to La Mancha Húmeda Biosphere Reserve. Nutrients, metalloids, isotopic composition (δ15N δ13C) were analysed faeces at several points Tablas de Daimiel National Park (TDNP), as well nearby Navaseca wetland, which receives inputs from a wastewater treatment plant (WWTP). Sediments one site that affected heron colonies (Garcera) TDNP showed higher concentrations organic matter, total carbon, nitrogen, phosphorus, Al, Co, Cu, Cr, Fe, Ni Zn than rest sampling sites. Significant correlations these variables found, probably suggesting they have common source. The highest δ15N values registered Guadiana, where there no impact colonies; might therefore be due anthropogenic activities. Metal metalloid content was lower regional reference soils, except for Se TDNP, Cu Navaseca. High level sediment may seleniferous soils located upstream. Results low droppings compared sources nutrients annual input TDNP.

Biodiversity of Mineral Nutrient and Trace Element Accumulation in Arabidopsis thaliana
In order to grow on soils that vary widely in chemical composition, plants have evolved mechanisms for regulating the elemental composition of their tissues to balance the mineral nutrient and trace element bioavailability in the soil with the requirements of the plant for growth and development. The biodiversity that exists within a species can be utilized to investigate how regulatory mechani...
متن کاملTrace element and nutrient accumulation in sunflower plants two years after the Aznalcóllar mine spill.
The failure of a tailing pond dam at the Aznalcóllar pyrite mine (SW Spain) in April 1998 released a toxic spill affecting approximately 4300 ha along the Agrio and Guadiamar valleys. Two years later, we have studied yield and concentration of mineral nutrients and trace elements in sunflower plants grown in the spill-affected soil, and in an adjacent unaffected soil as comparison. The study ha...

OBJECTIVE Although the genetic etiology of familial Mediterranean fever (FMF) is known, limited information is available regarding the regulation of inflammation during attack-free periods. The aim of this study was to determine the alterations in serum copper (Cu), zinc (Zn) and selenium (Se) levels that may be associated with inflammation during attack-free periods in FMF patients.

متن کاملBiomass, Nutrient, and Trace Element Accumulation and Partitioning in Cattail (Typha latifolia L.) during Wetland Phytoremediation of Municipal Biosolids
Biomass and contaminant accumulation and partitioning in plants determine the harvest stage for optimum contaminant uptake during phytoremediation of municipal biosolids. This wetland microcosm bioassay characterized accumulation and partitioning of biomass, nutrients (N and P), and trace elements (Zn, Cu, Cr, and Cd) in cattail (Typha latifolia L.) in a growth room. Four cattail seedlings were...
