  • Angling baits and invasive crayfish as important trophic subsidies for a large cyprinid fish 
    Basic, Tea; Britton, J. Robert; Jackson, Michelle C.; Reading, Peter; Grey, Jonathan (Springer, 2015-01)
    Invasive species and anthropogenic sources of allochthonous trophic subsidies can have substantial eco-logical consequences for freshwater ecosystems, including modifying the diet of consumers and altering food web ...
  • Between-lake variation in the trophic ecology of an invasive crayfish 
    Jackson, Michelle C.; Evangelista, Charlotte; Zhao, Tian; Lecerf, Antoine; Britton, J. Robert; Cucherousset, Julien (Wiley, 2017-09)
    1. The trophic ecology of invasive species has important implications for their impacts on recipient ecosystems, with omnivorous invaders potentially affecting native species and processes over multiple trophic levels. The ...
  • Dietary niche constriction when invaders meet natives : evidence from freshwater decapods 
    Jackson, Michelle C.; Donohue, Ian; Miller, Katie; Britton, J. Robert; Grey, Jonathan (Wiley, 2016-07)
    1. Invasive species are a key driver of global environm ental change, with frequently strongnegative consequences for native biodiversity and ecosystem processes. Understanding com-petitive interactions between invaders ...
  • Do non-native pumpkinseed Lepomis gibbosus affect the growth, diet and trophic niche breadth of native brown trout Salmo trutta? 
    Jackson, Michelle C.; Britton, J. Robert; Cucherousset, J.; Guo, Z.; Stakėnas, S.; Gozlan, R.E.; Godard, M.G.; Roussel, J-M.; Copp, G.H. (Springer, 2016-06)
    Brown trout Salmo trutta Linnaeus, 1758, is a priority species for conservation and management efforts in many European countries. In its native range, interactions with non-native fishes often adversely affect somatic ...
  • Food web properties vary with climate and land use in South African streams 
    Jackson, Michelle C.; Fourie, Hermina E.; Dalu, Tatenda; Woodford, Darragh J.; Wasserman, Ryan J.; Zengeya, Tsungai Alfred; Ellender, Bruce R.; Kimberg, Peter K.; Jordaan, Martine S.; Chimimba, Christian Timothy; Weyl, Olaf L.F. (Wiley, 2020-08)
    Land use intensification and climate change are two prominent drivers of variation in biological communities. However, we know very little about how these two potential environmental stressors interact. Here we use a stable ...
  • Interactions among multiple invasive animals 
    Jackson, Michelle C. (Ecological Society of America, 2015)
    With accelerating rates of invasion being documented in many ecosystems, communities of interacting invasive species are becoming increasingly common. Opposing theories predict that invaders can either hinder or promote ...
  • Net effects of multiple stressors in freshwater ecosystems : a meta-analysis 
    Jackson, Michelle C.; Loewen, Charlie J.G.; Vinebrooke, Rolf D.; Chimimba, Christian Timothy (Wiley, 2016-01)
    The accelerating rate of global change has focused attention on the cumulative impacts of novel and extreme environmental changes (i.e. stressors), especially in marine ecosystems. As integrators of local catchment and ...
  • Niche differentiation among invasive crayfish and their impacts on ecosystem structure and functioning 
    Jackson, Michelle C.; Jones, Tabitha; Milligan, Maaike; Sheath, Danny; Taylor, Jeff; Ellis, Adam; England, Judy; Grey, Jonathan (Wiley, 2014-06)
    1. Many aquatic ecosystems sustain multiple invasive species and interactions among them have important implications for ecosystem structure and functioning. Here, we examine interactions among two pairs of invasive ...
  • Patterns of trophic niche divergence between invasive and native fishes in wild communities are predictable from mesocosm studies 
    Tran, Thi Nhat Quyen; Jackson, Michelle C.; Sheath, Danny; Verreycken, Hugo; Britton, J. Robert (Wiley Open Access, 2015-07)
    1. Ecological theory attempts to predict how impacts for native species arise from biological invasions. A fundamental question centres on the feeding interactions of invasive and native species: whether invasion will ...
  • Population density modifies the ecological impacts of invasive species 
    Jackson, Michelle C.; Ruiz-Navarro, Ana; Britton, J. Robert (Wiley, 2015-07)
    In assessments of ecological impact in invasion ecology, most studies compare un-invaded sites with highly invaded sites, representing the ‘ worst-case scenario ’ , and so there is little information on how impact is ...
  • Recommendations for the next generation of global freshwater biological monitoring tools 
    Jackson, Michelle C.; Weyl, O.L.F.; Altermatt, F.; Durance, I.; Friberg, Nikolai; Dumbrell, A.J.; Piggott, J.J.; Tiegs, S.D.; Tockner, K.; Krug, C.B.; Leadley, P.W.; Woodward, G. (Elsevier, 2016)
    Biological monitoring has a long history in freshwaters, where much of the pioneering work in this field was developed over a 100 years ago—but few of the traditional monitoring tools provide the global perspective on ...
  • Reproductive ecology and diet of a persistent Ameiurus melas (Rafinesque, 1820) population in the UK 
    Ruiz-Navarro, Ana; Britton, J. Robert; Jackson, Michelle C.; Davies, G.D.; Sheath, Danny (Wiley, 2015-01)
    The black bullhead Ameiurus melas was introduced to Europe from North America in the early 20th Century and invasive populations are now present in many European countries (Novomesk a et al., 2013). Their invasion is ...
  • Temperature effects on fish production across a natural thermal gradient 
    O'Gorman, Eoin J.; Olafsson, Olafur P.; Demars, Benoit O.L.; Friberg, Nikolai; Gudbergsson, Gudni; Hannesdottir, Elisabet R.; Jackson, Michelle C.; Johansson, Liselotte S.; Mclaughlin, Orla B.; Olafsson, Jon S.; Woodward, Guy; Gislason, Gisli M. (Wiley, 2016)
    Global warming is widely predicted to reduce the biomass production of top predators, or even result in species loss. Several exceptions to this expectation have been identified, however, and it is vital that we understand ...
  • Trophic overlap between fish and riparian spiders : potential impacts of an invasive fish on terrestrial consumers 
    Jackson, Michelle C.; Woodford, Darragh J.; Bellingan, Terence A.; Weyl, Olaf L.F.; Potgieter, Michael J.; Rivers-Moore, Nick A.; Ellender, Bruce R.; Fourie, Hermina E.; Chimimba, Christian Timothy (Wiley Open Access, 2016)
    Studies on resource sharing and partitioning generally consider species that occur in the same habitat. However, subsidies between linked habitats, such as streams and riparian zones, create potential for competition ...
