Urbanisation is one of the greatest threats to freshwater biodiversity, with the area of land covered by towns and cities predicted to increase significantly in the future. Ponds are common features in the urban landscape and have been created for a variety of reasons ranging from ornamental/amenity purposes through to the detention of urban runoff and(More)
– Tree-grass systems occupy nearly a quarter of the terrestrial surface (27 million km 2). They face an uncertain future given pressures from land use change and climate change. Serious systems analysis, modeling, scenario development and ecosystems futures assessment for savannas is needed to avoid past mistakes in land management. Integration of(More)

Description: River Science is a rapidly developing interdisciplinary field at the interface of the natural sciences, engineering and socio–political sciences. It recognises that the sustainable management of contemporary rivers will increasingly require new ways of characterising them to enable engagement with the diverse range of stakeholders.

Agricultural drainage ditches are ubiquitous features in lowland agricultural landscapes, built primarily to facilitate land drainage, irrigate agricultural crops and alleviate flood risk. Most drainage ditches are considered artificial waterbodies and are not typically included in routine monitoring programmes, and as a result the faunal and floral(More)
Michael Hili opened the session and gave an introduction by presenting a comparison between the 1985 and the 1991 European Cancer Prevention Organization (ECP) meetings on nutrition and cancer. In 1985, specific recommendations regarding the intakes offat, fibres, energy, fruit & vegetables, alcohol and salt were given (see Michael Hill's article in this(More)
Ponds are sites of high biodiversity and conservation value, yet there is little or no statutory monitoring of them across most of Europe. There are clear and standardised protocols for sampling aquatic macroinvertebrate communities in ponds, but the most suitable time(s) to undertake the survey(s) remains poorly specified. This paper examined the aquatic(More)
The distribution of lotic fauna is widely acknowledged to be patchy reflecting the interaction between biotic and abiotic factors. In an in situ field study, the distribution of benthic and hyporheic invertebrates in the heads (downwelling) and tails (upwelling) of riffles were examined during stable baseflow conditions. Riffle heads were found to contain a(More)
