Abstract Terrestrial adult stages of freshwater insects may be exposed to pesticides by wind drift, over-spray, contact or feeding. However, studies addressing insecticide effects on freshwater invertebrates focus primarily on the impact of pesticides reaching the streams and potentially harming the aquatic juvenile stages. This is also reflected in the current risk assessment procedures, which do not include testing of adult freshwater insects. In order to assess the potential impact of insecti...

QUESTIONS: The change in the frequencies of invasive higher plant species in different habitat types was investigated using Danish monitoring data from 2004 to 2014. LOCATION: Denmark. METHODS: The occurrence data were collected in circles with a radius of 5 m at a number of plots within 923 sites. The sampling intensity was irregular with sampling intervals ranging from one to three years. The hierarchical occurrence data were fitted in a hierarchical model, where the site‐specific occurrence p...

1.Insecticides are important drivers of biodiversity loss and ecological impairment in freshwater ecosystems. Freshwater insects may be exposed to insecticides via water during larval/nymph stages and via air, habitats, and food during adult stages in the terrestrial environment. 2.The aquatic risk assessment (RA) of pesticides does not consider terrestrial life stages, and a literature review revealed that pesticide ecotoxicity data for adult freshwater insects are very scarce and outdated. Con...

In order to improve forecasting of aphid epidemics, it is important to know the spatial scale at which specific forecasts are reliable. To investigate the spatial scale of aphid epidemics, we have developed a spatio-temporal stochastic aphid population growth model, and fitted the model to empirical spatial time-series aphid population data using a Bayesian hierarchical fitting procedure. Furthermore, detailed spatial data of the initial phases of epidemic development was investigated in a semiv...

Abstract This paper aims at characterizing the response of hedgerow ground flora to conversion of the surrounding fields from conventional farming to an organic farming practice. The effect of time since conversion from conventional to organic farming on the neighbouring hedgerow vegetation was examined by measuring selection on plant species and plant traits in the ground flora of 57 hedgerows adjacent to agricultural fields subject to organic or conventional management. Species richness increa...
