Drivers of nitrogen transfer in stream food webs across continents.
Studies of trophic-level material and energy transfers are central to ecology. The use of isotopic tracers has now made it possible to measure trophic transfer efficiencies of important nutrients and to better understand how these materials move through food webs. We analyzed data from thirteen 15 N-ammonium tracer addition experiments to quantify N transfer from basal resources to animals in h...
متن کاملInvasibility of plankton food webs along a trophic state gradient
Biological invasions are becoming more common, yet the majority of introduced exotic species fail to establish viable populations in new environments. Current ecological research suggests that invasion success may be determined by properties of the native ecosystem, such as the supply rate of limiting nutrients (i.e. trophic state). We examined how trophic state influences invasion success by i...
متن کاملVirulence reaction norms across a food gradient.
Host-parasite interactions involve competition for nutritional resources between hosts and the parasites growing within them. Consuming part of a host's resources is one cause of a parasite's virulence, i.e. part of the fitness cost imposed on the host by the parasite. The influence of a host's nutritional conditions on the virulence of a parasite was experimentally tested using the mosquito Ae...
متن کاملStream communities across a rural–urban landscape gradient
Rapid urbanization throughout the world is expected to cause extensive loss of biodiversity in the upcoming decades. Disturbances associated with urbanization frequently operate over multiple spatial scales such that local species extirpations have been attributed both to localized habitat degradation and to regional changes in land use. Urbanization also may shape stream communities by restric...
متن کاملFood webs
Ecosystems, whether they are forests, lakes or coral reefs, consist of a diverse range of species that interact with each other in many ways. As ecologists we want to understand how these complex systems function as a whole and how they respond to human impacts such as harvesting and environmental change. A mechanistic understanding of the underlying biological processes will allow us to predic...
