  abstract = {{R}ecent work has shown that evaluating functional trait distinctiveness, the average trait distance of a species to other species in a community offers promising insights into biodiversity dynamics and ecosystem functioning. {H}owever, the ecological mechanisms underlying the emergence and persistence of functionally distinct species are poorly understood. {H}ere, we address the issue by considering a heterogeneous fitness landscape whereby functional dimensions encompass peaks representing trait combinations yielding positive population growth rates in a community. {W}e identify four ecological cases contributing to the emergence and persistence of functionally distinct species. {F}irst, environmental heterogeneity or alternative phenotypic designs can drive positive population growth of functionally distinct species. {S}econd, sink populations with negative population growth can deviate from local fitness peaks and be functionally distinct. {T}hird, species found at the margin of the fitness landscape can persist but be functionally distinct. {F}ourth, biotic interactions (positive or negative) can dynamically alter the fitness landscape. {W}e offer examples of these four cases and guidelines to distinguish between them. {I}n addition to these deterministic processes, we explore how stochastic dispersal limitation can yield functional distinctiveness. {O}ur framework offers a novel perspective on the relationship between fitness landscape heterogeneity and the functional composition of ecological assemblages.},
