    Impacts of an aggressive riparian invader on community structure and ecosystem functioning in stream food webs

    , Journal of Applied Ecology, Vol: 48, Pages: 443-452, ISSN: 0021-8901

    <jats:title>Summary</jats:title><jats:p> <jats:bold>1.</jats:bold> Bioassessment in running waters has focused primarily on the impacts of organic pollution on community structure. Other stressors (e.g. invasive species) and impacts on ecosystem processes have been largely ignored in many riverine biomonitoring schemes, despite being required increasingly by environmental legislation.</jats:p><jats:p> <jats:bold>2.</jats:bold> Exotic riparian plants can exert potentially powerful stresses by altering both autochthonous and allochthonous trophic pathways. We examined the impact of <jats:italic>Rhododendron ponticum</jats:italic> on community structure and three key ecosystem processes (decomposition, primary production, and herbivory) in nine streams bordered by three characteristic vegetation types (deciduous woodland, pasture, or <jats:italic>Rhododendron</jats:italic>).</jats:p><jats:p> <jats:bold>3.</jats:bold> Community structure and ecosystem process rates differed among vegetation types, with autochthonous pathways being relatively more important in the pasture streams than in the woodland reference streams. Overall ecosystem functioning, however, was compromised in the invaded streams because both allochthonous and autochthonous inputs were impaired. <jats:italic>Rhododendron</jats:italic>’s poor quality litter and densely shaded canopy suppressed decomposition rates and algal production, and the availability of resources to consumer assemblages.</jats:p><jats:p> <jats:bold>4.</jats:bold> <jats:italic>Synthesis and applications</jats:italic>. Combining measures of invertebrate abundance, rates of litter decomposition and algal production in future bioassessments of stream ecosystem functioning can help to make better informed management decisions and to develop more focused priorities f

    Warming increases the proportion of primary production emitted as methane from freshwater mesocosms

    , Global Change Biology, Vol: 17, Pages: 1225-1234, ISSN: 1354-1013

    <jats:title>Abstract</jats:title><jats:p>Methane (CH<jats:sub>4</jats:sub>) and carbon dioxide (CO<jats:sub>2</jats:sub>) are the dominant gaseous end products of the remineralization of organic carbon and also the two largest contributors to the anthropogenic greenhouse effect. We investigated whether warming altered the balance of CH<jats:sub>4</jats:sub> efflux relative to gross primary production (GPP) and ecosystem respiration (ER) in a freshwater mesocosm experiment. Whole ecosystem CH<jats:sub>4</jats:sub> efflux was strongly related to temperature with an apparent activation energy of 0.85 eV. Furthermore, CH<jats:sub>4</jats:sub> efflux increased faster than ER or GPP with temperature, with all three processes having sequentially lower activation energies. Warming of 4 °C increased the fraction of GPP effluxing as CH<jats:sub>4</jats:sub> by 20% and the fraction of ER as CH<jats:sub>4</jats:sub> by 9%, in line with the offset in their respective activation energies. Because CH<jats:sub>4</jats:sub> is 21 times more potent as a greenhouse gas, relative to CO<jats:sub>2</jats:sub>, these results suggest freshwater ecosystems could drive a previously unknown positive feedback between warming and the carbon cycle.</jats:p>
