Simulating the Holocene climate evolution at northern high latitudes using a coupled atmosphere-sea ice-ocean-vegetation model
The response of the climate at high northern latitudes to slowly changing external forcings was studied in a 9,000-year long simulation with the coupled atmosphere-sea ice-ocean-vegetation model ECBilt-CLIO-VECODE. Only long-term changes in ...

Optimal estimation of atmospheric 14C production over the Holocene: paleoclimate implications
A tree-ring 14C record and a simple box model of the global 14C cycle are combined using a method of optimal estimation theory (Rauch-Tung-Striebel smoother). The combination is used to infer information about the time evolution of 14C production in ...

Eight nonnative plants in western Oregon forests: Associations with environment and management
Nonnative plants have tremendous ecological and economic impacts on plant communities globally, but comprehensive data on the distribution and ecological relationships of individual species is often scarce or nonexistent. The objective of this study ...

Comparison of data from two vegetation monitoring methods in semi-natural grasslands
Two vegetation-monitoring methods were compared: subplot frequency analysis (SF) and visual estimation of percentage cover (VE). Two independent observers collected data from two semi-natural, species-rich grasslands on three different occasions ...

Restoration of Some Parameters in the Development of Benthos After Reduction of Anthropogenous Loading in the Ecosystem of the Sevastopol Bay in the Black Sea
Research on benthic communities have been carried out in the Sevastopol Bay of the Black Sea for a hundred years. The anthropogenous influence began to have an effect already in the 20–30th. In this period, all oyster-banks were lost and the ...

Qualitative Stakeholder Analysis for the Development of Sustainable Monitoring Systems for Farm Animal Welfare
Continued concern for animal welfare may be alleviated when welfare would be monitored on farms. Monitoring can be characterized as an information system where various stakeholders periodically exchange relevant information. Stakeholders include ...

Changes in rhizosphere microbial activity mediated by native or allochthonous AM fungi in the reafforestation of a Mediterranean degraded environment
This study was carried out in a semiarid degraded area to assess the effectiveness of mycorrhizal inoculation with a mixture of native arbuscular mycorrhizal (AM) fungi or an allochthonous AM fungus (Glomus claroideum), on the establishment of Olea ...

Photocatalytic degradation of the herbicide cinosulfuron in aqueous TiO 2 suspension
Abstract The photocatalytic degradation of a sulfonylurea herbicide, cinosulfuron, has been studied in TiO 2 aqueous suspensions. A first order kinetic law was found. The influence of the initial concentration of cinosulfuron and of the initial ...

Copper distribution in chemical soil fractions and relationships with maize crop yield
Abstract Agricultural practices can lead to copper accumulation in soils and at high concentration it can become toxic for plants. One common toxic effect of copper on plants is a decrease of crop yield. Here, we studied 1) the crop yield of maize ...
