Abstract:Clonal growth can be especially advantageous in spatially heterogeneous environments and some clonal plants are highly invasive or superdominant, especially in disturbed environments. However, their temporal dynamics in the absence of large disturbances are not well known. We assessed whether patches dominated by the native bracken fern Pteridium arachnoideum expanded or retracted in area over six years. We mapped the contour of eight patches occupied by P. arachnoideum in a savanna-forest transition every two… Show more
