The role of timing in intraspecific trait ecology

Trait variation within species is important for shaping ecological interactions and communities. Traits vary greatly through individual ontogenetic and phenological development, and individuals within populations vary in their developmental timing. Timing therefore must be important for understanding intraspecific trait variation and its effects on ecology. However, this is rarely considered in the field. A temporally explicit approach to the study of intraspecific trait variation in ecology is needed to fully understand population and community dynamics. Intraspecific trait variation has tremendous importance for species interactions and community composition. A major source of intraspecific trait variation is an organism’s developmental stage; however, timing is rarely considered in studies of the ecological effects of intraspecific variation. Here, we examine the role of time in the ecology of intraspecific trait variation, focusing on plants and their interactions with other organisms. Trait variation due to differences in developmental timing has unique features and dynamics, distinguishing it from variation due to genes or the environment. When time is considered in studies of intraspecific trait ecology, the degree of variability in timing within a population becomes a key factor structuring trait-mediated ecological interactions and community processes.
