On Testing the Competition‐Colonization Trade‐Off in a Multispecies Assemblage

Abstract: The competition-colonization trade-off has long been considered an important mechanism explaining species coexistence in spatially structured environments, yet data supporting it remain ambiguous. Most competition-colonization research examines plants and the dispersal-linked traits of their seeds. However, colonization is more than just dispersal because rapid population growth is also an important component of colonization. We tested for the presence of competition-colonization trade-offs with a commonly use… Show more

“…Species-poor communities are generally linked to recently formed water bodies (see , or to particular environmental conditions selecting for a reduced pool of ''stress-adapted'' species (Naselli-Flores et al, 2003). Species-rich communities show stronger and more complex biotic interactions that can impair the colonization success of new immigrants (Shurin, 2000;Cadotte et al, 2006). Moreover, immigrants can undergo Allee effects (Sarnelle & Knapp, 2004) which would further slow down their population growth rates.…”

“…Strong interference competitors can monopolize the highest quality resources, but may ignore lower quality resources, providing the opportunity for a subdominant competitor to coexist locally (Alatalo and Moreno, 1987). Moreover, interference ability often comes at the expense of investment in other traits such as dispersal, abiotic tolerances, reproductive investment or efficiency of resource use (Tilman, 1994;Hughes et al, 2003;Pfennig and Pfennig, 2005;Cadotte et al, 2006). Such trade-offs may allow species that are poor interference competitors to persist because the costs of strong interference ability may not be supported on low quality resources.…”

“…Despite a general acceptance of the theoretical framework, to our knowledge there is no direct experimental treatment of the general predictions of the CC theory; in fact, indirect tests that attempted to document the existence of the CC trade-off have produced contradictory results in experimental [10][11][12][13] and observational studies of natural species assemblages [14][15][16][17][18] . Moreover, because the existence of a CC trade-off in an assemblage does not necessarily indicate that CC dynamics are determinant, indirect approaches have limited power to evaluate the theory.…”
