Analysis of carbon and nitrogen dynamics in riparian soils: Model development

David Andrew Barry, Alessandro Brovelli, Jordi Batlle-Aguilar

The quality of riparian soils and their ability to buffer contaminant releases to aquifers and streams are connected intimately to moisture content and nutrient dynamics, in particular of carbon (C) and nitrogen (N). A multi-compartment model – named the R ...

Modelling of biogeochemical transformations in riparian soils: lessons learned from the Thur river revitalization experiment and open questions

David Andrew Barry, Alessandro Brovelli

In recent years, the key environmental importance of natural, healthy riparian ecosystems and soils has been recognized and restoration of degraded lands towards their former natural state has become an area of active research worldwide. Land use changes a ...

Using Plants to Remove Foreign Compounds from Contaminated Water and Soil

Jean-Paul Schwitzguebel

Depending on the physico-chemical properties of the organic pollutant to be removed or detoxified, as well as on the specific plant physiology and biochemistry, different phytotreatments are available to decontaminate water and soils. For example, aquatic ...

Modelling soil carbon and nitrogen cycles during land use change

David Andrew Barry, Alessandro Brovelli, Jordi Batlle-Aguilar

Forested soils are being increasingly transformed to agricultural fields in response to growing demands for food crop. This modification of the land use is known to result in deterioration of soil properties, in particular its fertility. To reduce the impa ...

Rediscovery of Nebela ansata (Amoebozoa: Arcellinida) in eastern North America: biogeographical implications

Edward Mitchell, Thierry Jean Heger

Aim The question whether free-living protists are generally cosmopolitan is currently a matter of debate. In this study we investigate the geographical distribution of a distinctive testate amoeba species, Nebela ansata, and use our data to assess the pote ...

Carbon and nitrogen dynamics in a soil profile: Model insights and application to a restored Swiss riparian area

David Andrew Barry, Alessandro Brovelli, Jordi Batlle-Aguilar, Pascal Niklaus

2010

A long-standing debate in microbial ecology is the extent to which free-living microorganisms exhibit cosmopolitan distributions. We use a comparison of testate amoebae communities in cold "polar" locations (Arctic, Antarctic, and Tibet) to investigate how ...

In order to meet demands for crops, pasture and firewood, the rate of land use change from forested to agricultural uses steadily increased over several decades, resulting in an increased release of nutrients towards groundwater and surface water bodies. I ...

Anthropogenic nutrient enrichment of mountain grasslands has boosted grasses and fast-growing unpalatable plants at the expense of slow-growing species, resulting in a significant loss in biodiversity. A potential tool to reduce nutrient availability and a ...
