Intraspecific leaf trait variability along a boreal-to-tropical community diversity gradient
Disentangling the mechanisms that shape community assembly across diversity gradients is a central matter in ecology. While many studies have explored community assembly through species average trait values, there is a growing understanding that intraspecific trait variation (ITV) can also play a critical role in species coexistence. Classic biodiversity theory hypothesizes that higher diversit...
متن کاملThe Contribution of Intraspecific Trait Variability to Plant Community Assembly Patterns on the Niche-neutral Continuum
Many trait-based plant investigations have neglected the intraspecific trait variations. A lot of ecologists consider that this is unreasonable, because intraspecific variation significantly affects various ecological dynamics. However, it is not feasible to record the traits of each plant individually at every community site. Therefore, the aim of this study was to determine in which circumsta...
متن کاملBark flammability as a fire-response trait for subalpine trees
Relationships between the flammability properties of a given plant and its chances of survival after a fire still remain unknown. We hypothesize that the bark flammability of a tree reduces the potential for tree survival following surface fires, and that if tree resistance to fire is provided by a thick insulating bark, the latter must be few flammable. We test, on subalpine tree species, the ...
متن کاملIntraspecific growth and functional leaf trait responses to natural soil resource gradients for conifer species with contrasting leaf habit.
Interspecific relationships among species mean leaf traits, performance and species resource/climate distributions help provide the foundation for a predictive, functionally based plant ecology. Intraspecific responses of leaf traits and performance to resource gradients and how these vary among species may be equally important but have received less attention. Here, we examine relationships be...
متن کاملWhen does intraspecific trait variation contribute to functional betadiversity?
1. Intraspecific trait variation (ITV) is hypothesized to play an important role in community assembly and the maintenance of biodiversity. However, fundamental gaps remain in our understanding of how ITV contributes to mechanisms that create spatial variation in the functional-trait composition of communities (functional b-diversity). Importantly, ITV may influence the perceived importance of ...
