Competition between Invasive and Indigenous Species: Impact of Spatial Pattern and Developmental Stage



Elodea canadensis (indigenous) and Elodea nuttallii (invasive) were grown in experimental tanks in monocultures and mixtures in two spatial patterns (aggregated or mixed) and two developmental stages (small or large plants of E. canadensis , and small plants of E. nuttallii ). Competitive interactions between the two species were assessed by monitoring the area colonised by each species, the number of rootings and biomass after 10 weeks. In monocultures the growth of E. canadensis was significantly lower than that of E. nuttallii . In mixtures the number of rootings and biomass of E. canadensis were always significantly less than those of E. nuttallii . The tank surface area colonised by E. canadensis was always significantly less than that occupied by E. nuttallii , but it was higher in the aggregated treatment, where the colonisation of E. nuttallii was lower. Therefore both spatial pattern and developmental stage of an indigenous species ( E. canadensis ) may influence the outcome of competition with potential invaders ( E. nuttallii ).
