    Anthropogenic Eutrophication Drives Major Food Web Changes in Mwanza Gulf, Lake Victoria

    Discerning ecosystem change and food web dynamics underlying anthropogenic eutrophication and the introduction of non-native species is necessary for ensuring the long-term sustainability of fisheries and lake...

    Shifts in isotopic signatures of animals with complex life-cycles can complicate conclusions on cross-boundary trophic links

    Stable isotopes (13C and 15N) are widely applied in studies of trophic links. We used this method to investigate the contribution of aquatic and terrestrial prey to the diet of riparian predatory arthropods in tw...

    Bacterial, Archaeal and Fungal Succession in the Forefield of a Receding Glacier

    Glacier forefield chronosequences, initially composed of barren substrate after glacier retreat, are ideal locations to study primary microbial colonization and succession in a natural environment. We characte...

    Tracking the fate of digesta 13C and 15N compositions along the ruminant gastrointestinal tract: Does digestion influence the relationship between diet and faeces?

    Faecal stable isotope compositions reflect wildlife diets, if digestive processes along the gastrointestinal tract (GIT) do not alter diet–faeces isotopic relationships in an unpredictable way. We investigated 13

    Nitrogen recoveries from organic amendments in crop and soil assessed by isotope techniques under tropical field conditions

    The integration of multipurpose legumes into low-input tropical agricultural systems is needed because they are a nitrogen (N) input through symbiotic fixation. The drought-tolerant cover legume canavalia (Canava...

    Functional measures and food webs of high elevation springs in the Swiss alps

    We examined the ecosystem functioning and food webs of high elevation springs in or near the Swiss National Park. Springs originated from silicate or carbonate geologies and were near or above treeline. One ir...

    Use of isotopic and molecular techniques to link toluene degradation in denitrifying aquifer microcosms to specific microbial populations

    Microcosms were inoculated with sediments from both a petroleum-hydrocarbon (PHC)-contaminated aquifer and from a nearby pristine aquifer and incubated under anoxic denitrifying conditions with [methyl-13C]tolue...
