Distribution of agricultural pesticides in the freshwater environment of the Guayas river basin (Ecuador)
Seasonal changes in the biochemical fate of carbon fixed by benthic diatoms in intertidal sediments
Benthic diatoms are important primary producers in intertidal marine sediments and form the basis of the food web in these ecosystems. In order to investigate the carbon flow within diatom mats, we performed in situ 13C pulse-chase labeling experiments and followed in detail the biochemical fate of carbon fixed by the diatoms for five consecutive d...
Implications of movement for species distribution models : rethinking environmental data tools
Radiological dose rates to marine fish from the Fukushima Daiichi accident
The dose rates for six marine organisms, pelagic fish, benthic fish, mollusks, crustaceans, macroalgae, and polychaete worms, representative in marine ecosystems, have been predicted by the equilibrium model with the measured seawater activity concentrations at three locations around the Fukushima Daiich nuclear power plant after the accident on Ma...
Identifying heavy metal levels in historical flood water deposits using sediment cores
When designing mitigation and restoration strategies for aquatic systems affected by heavy metal contamination, we must first understand the sources of these pollutants. In this study, we introduce a methodology that identifies the heavy metal levels in floodplain lake sediments deposited by one source; fluvial floods. This is done by comparing sed...
Marine water from mid-holocene sea level highstand trapped in a coastal aquifer: Evidence from groundwater isotopes, and...
A multi-layered coastal aquifer in southeast Australia was assessed using environmental isotopes, to identify the origins of salinity and its links to palaeo-environmental setting. Spatial distribution of groundwater salinity (electrical conductivity values ranging from 0.395 to 56.1 mS/cm) was examined along the coastline along with geological, is...
Impoundment constraint of fish niche diversity in a temperate Australian river.
Dams constitute a major threat to aquatic ecosystems world-wide by modifying habitat and impairing opportunities for many freshwater fish. Subsequently, there can be a loss in fish diversity and change in the species distributions and population structure that ultimately contribute to changes in trophic structure and ecosystem function. In this stu...
Biochemical and toxicological effects of organic (herbicide Primextra® Gold TZ) and inorganic (copper) compounds on zoop...

Assessment of Hg pollution released from a WWII submarine wreck (U-864) by Hg isotopic analysis of sediments and Cancer ...
Hg pollution released from the U-864 submarine sunk during WWII and potential introduction of that Hg into the marine food,chain have been studied by a combination of quantitative Hg and MeHg determination and Hg isotopic analysis via cold vapor generation multicollector inductively coupled plasma-mass spectrometry (CVG-MC-ICP-MS) in sediment and C...
